PROSPECTUS SUMMARY

	•	Rising and Volatile Energy Prices. Over the past decade, energy-linked commodity prices, including oil, gas, coal and electricity, have all increased and exhibited significant volatility. From 1999 to 2009, average U.S. retail electricity prices have increased by more than 50%.
	•	Potential of Energy Efficiency Measures to Significantly Reduce Energy Consumption. The implementation of energy efficiency measures can significantly reduce the rate at which energy consumption is expected to increase. According to a July 2009 report by McKinsey & Company, economically viable and commercially available energy efficiency measures, if fully implemented, have the potential to save more than one trillion kWh of electricity, or 23% of overall U.S. demand, by 2020.
	•	Aging and Inefficient Facility Infrastructure. Many organizations continue to operate with an energy infrastructure that is significantly less efficient and cost-effective than now available through more advanced technologies applied to lighting, heating, cooling and other building systems. As these organizations explore alternatives for renewing their aging facilities, they often identify multiple areas within their facilities that could benefit from the implementation of energy efficiency measures, including the possible use of renewable sources of energy.
	•	Increased Focus on Cost Reduction. The current economic environment has led many organizations to search for opportunities to reduce their operating costs. There has been a growing awareness that reduced energy consumption presents an opportunity for significant long-term savings in operating costs and that the installation of energy efficiency measures can be a cost-effective way to achieve such reductions.
	•	Movement Toward Industry Consolidation. As energy efficiency solutions continue to increase in technological complexity and customers look for service providers that can offer broad geographic and product coverage, we believe smaller niche energy efficiency companies will continue to look for opportunities to combine with larger companies that can better serve their customers’ needs. Increased market presence and size of energy efficiency companies should, in turn, create greater customer awareness of the benefits of energy efficiency measures.
	•	Increasing Legislative Support and Initiatives. In the United States and Canada, federal, state, provincial, and local governments have enacted and are considering legislation and regulations aimed at increasing energy efficiency, reducing greenhouse gas emissions and encouraging the expansion of renewable energy generation.
	•	Increased Use of Third-Party Financing. Many organizations desire to use their existing sources of capital for core investments or do not have the internal capacity to finance improvements to their energy infrastructure. These organizations often require innovative structures to facilitate the financing of energy efficiency and renewable energy projects. Customers seeking to upgrade or renew their energy systems are increasingly seeking to enter into ESPCs or other creative arrangements that facilitate third-party financing for their projects.

	•	One-Stop, Comprehensive Service Provider. We offer our customers expertise in addressing almost all aspects of purchasing and using energy within a facility. Our experienced project development and engineering staff provide us with the capability and flexibility to determine the combination of energy efficiency measures that is best suited to achieve the customer’s energy efficiency and environmental goals.
	•	Independence. We are an independent company with no affiliation to any equipment manufacturer, utility or fuel company. Unlike affiliated service companies, we have the freedom and flexibility to be objective in selecting particular products and technologies available from different manufacturers in order to optimize our solutions for customers’ particular needs.
	•	Strong Customer Relationships. We have served over 2,000 customers since our inception, including over 1,000 customers in 2009. Our design, engineering and support activities, which typically span multiple years, foster a close relationship with our customers, which positions us to identify their future needs and provide additional services to them.
	•	Creative Solutions. Our engineering staff has expertise in a broad range of technologies and energy savings strategies encompassing different types of electrical, heating, cooling, lighting, water, renewable energy and other facility infrastructure systems. We apply this expertise to design and engineer innovative solutions customized to meet the specific needs of each customer.
	•	Strong National and Local Presence. We have a nationwide presence in both the United States and Canada and serve certain of our customers in European locations. We maintain a centralized staff of engineering, financial and legal personnel at our headquarters in Massachusetts, who provide support to our seven regional offices and 46 other field offices located throughout the United States and Canada. We believe that our organizational structure enables us to be fast, flexible and cost-effective in responding to our customers’ needs.
	•	Experienced Management and Operations Team. Our executive officers have an aggregate of over 150 years of experience in the energy efficiency field. As of March 31, 2010, we employed over 200 engineers, whose experience with respect to fuels, rates, technologies and geography-specific regulation and economic benefits enables us to propose and design energy efficiency solutions that take into account the economic, technological, environmental and regulatory considerations that we believe underlie the cost efficiencies and operational success of a project.
	•	Federal and State Qualifications. The federal governmental program under which federal agencies and departments can enter into ESPCs requires that energy service providers have a track record in the industry and meet other specified qualifications. Over 20 states require similar qualifications. In 2008, we renewed our qualification to enter into an indefinite delivery, indefinite quantity, or IDIQ, contract under the U.S. Department of Energy program for ESPCs. This IDIQ contract has an aggregate maximum potential ordering amount of $5 billion and expires in 2019. We are currently qualified to enter into ESPCs in most states that require qualification. The scope of our qualifications provides us with the opportunity to continue to grow our business with federal, state and other governmental customers and differentiates us from energy efficiency companies that have not been similarly qualified.
	•	Integration of Strategic Acquisitions. We have a track record of completing over ten acquisitions that have enabled us to broaden our offerings, expand our geographical reach and accelerate our growth. We believe that our ability to offer a comprehensive set of energy efficiency services across North America has been, and will continue to be, enhanced by our expertise in identifying and completing acquisitions that expand our service offerings, as well as by our ability to integrate and leverage the skilled engineering, sales and operational personnel that come to us through these acquisitions.

	•	Pursue Organic Growth. We plan to open additional local offices in the regions we currently serve, as well as hire additional sales personnel. We also plan to expand geographically by opening new local offices in regions we do not currently serve in the United States and Canada, as well as in Europe.
	•	Continue to Maintain Customer Focus. We will continue to maintain an entrepreneurial approach toward our customers and remain flexible in designing projects tailored specifically to meet their needs.
	•	Expand Scope of Product and Service Offerings. We plan to continue to expand our offerings by including new types of energy efficiency services, products and improvements to existing products based on technological advances in energy savings strategies, equipment and materials.
	•	Meet Market Demand for Cost-Effective, Environmentally-Friendly Solutions.  Through our energy efficiency measures and small-scale renewable energy plants and products, we enable customers to conserve energy and reduce emissions of carbon dioxide and other pollutants. We plan to continue to focus on providing sustainable energy solutions that will address the growing demand for products and services that create environmental benefits for customers.
	•	Increase Recurring Revenue. For many of our energy efficiency projects, we enter into multi-year O&M contracts, and we plan to continue to grow both the number and scope of such contracts. We also obtain recurring revenue from sales of electricity, thermal energy and gas generated by the small-scale renewable energy and central plants that we construct and own, and we plan to continue to seek opportunities to construct such plants.
	•	Grow Through Select Strategic Acquisitions. We plan to continue to pursue complementary acquisitions that will enable us to both expand geographically in North America and abroad, and broaden our product and service offerings.

(2)		We define adjusted EBITDA as operating income before depreciation and impairment expense, share-based compensation expense and a non-recurring non-cash recovery of a contingency in 2008. Adjusted EBITDA is a non-GAAP financial measure and should not be considered as an alternative to operating income or any other measure of financial performance calculated and presented in accordance with GAAP.

	•	adjusted EBITDA and similar non-GAAP measures are widely used by investors to measure a company’s operating performance without regard to items that can vary substantially from company to company depending upon financing and accounting methods, book values of assets, capital structures and the methods by which assets were acquired;
	•	securities analysts often use adjusted EBITDA and similar non-GAAP measures as supplemental measures to evaluate the overall operating performance of companies; and

	•	by comparing our adjusted EBITDA in different historical periods, our investors can evaluate our operating results without the additional variations of depreciation and amortization expense, share-based compensation expense and the non-recurring non-cash recovery of a contingency in 2008.

	•	as a measure of operating performance, because it does not include the impact of items that we do not consider indicative of our core operating performance;
	•	for planning purposes, including the preparation of our annual operating budget;
	•	to allocate resources to enhance the financial performance of our business;
	•	to evaluate the effectiveness of our business strategies; and
	•	in communications with our board of directors and investors concerning our financial performance.

	•	adjusted EBITDA does not reflect our cash expenditures or future requirements for capital expenditures or other contractual commitments;
	•	adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;
	•	adjusted EBITDA does not reflect stock-based compensation expense;
	•	adjusted EBITDA does not reflect cash requirements for income taxes;
	•	adjusted EBITDA does not reflect net interest income (expense);
	•	although depreciation, amortization and impairment are non-cash charges, the assets being depreciated, amortized or impaired will often have to be replaced in the future, and adjusted EBITDA does not reflect any cash requirements for these replacements; and
	•	other companies in our industry may calculate adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure.

An investment in our Class A common stock involves a high degree of risk. In deciding whether to invest, you should carefully consider the following risk factors. Any of the following risks could have a material adverse effect on our business, financial condition and operating results and cause the value of our Class A common stock to decline, which could cause you to lose all or part of your investment. When determining whether to invest in our Class A common stock, you should also refer to the other information in this prospectus, including the consolidated financial statements and related notes.

 

If demand for our energy efficiency and renewable energy solutions does not develop as we expect, our revenue will suffer and our business will be harmed.

 

Our revenue has increased significantly since January 1, 2005. We believe, and our growth expectations assume, that the market for energy efficiency and renewable energy solutions will continue to grow, that we will increase our penetration of this market and that our revenue from selling into this market will continue to increase. If our expectations as to the size of this market and our ability to sell our products and services in this market are not correct, our revenue will suffer and our business will be harmed.

 

The projects we undertake for our customers generally require significant capital, which our customers or we may finance through third parties, and such financing may not be available to our customers or to us on favorable terms, if at all.

 

Our projects are typically financed by third parties. The cost of these projects to our customers can reach up to $200 million. For our energy efficiency projects, we often assist our customers in arranging third-party financing. For small-scale renewable energy plants that we own, we typically rely on a combination of our working capital and debt to finance construction costs. The significant disruptions in the credit and capital markets in the last several years have made it more difficult for our customers and us to obtain financing on acceptable terms or, in some cases, at all. If we or our customers are unable to raise funds on acceptable terms when needed, we may be unable to secure customer contracts, the size of contracts we do obtain may be smaller or we could be required to delay the development and construction of projects, reduce the scope of those projects or otherwise restrict our operations.

 

In 2008, we entered into a $50 million revolving senior secured credit facility that matures in June 2011. Availability under the facility is based on two times our EBITDA for the preceding four quarters, and we are required to maintain a minimum EBITDA of $20 million on a rolling four-quarter basis and a minimum level of tangible net worth. This facility may not be sufficient to meet our needs as our business grows, and we may be unable to extend or replace it on acceptable terms, or at all.

 

Any inability by us or our customers to raise the funds necessary to finance our projects, or any inability by us to extend or replace our revolving credit facility, could materially harm our business, financial condition and operating results.

 

Our operating results may fluctuate significantly from quarter to quarter and may fall below expectations in any particular fiscal quarter.

 

Our operating results are difficult to predict and have historically fluctuated from quarter to quarter due to a variety of factors, many of which are outside of our control. As a result, comparing our operating results on a period-to-period basis may not be meaningful, and you should not rely on our past results as an indication of our future performance. If our revenue or operating results fall below the expectations of investors or any securities analysts that follow our company in any period, the trading price of our Class A common stock would likely decline.

 

Factors that may cause our operating results to fluctuate include:

 

 

Our operating expenses do not always vary directly with revenue and may be difficult to adjust in the short term. As a result, if revenue for a particular quarter is below our expectations, we may not be able to proportionately reduce operating expenses for that quarter, and therefore such a revenue shortfall could have a disproportionate effect on our operating results for that quarter.

 

We may not be able to maintain or increase our profitability.

 

We have been profitable on an annual basis since the year ended December 31, 2002. However, we have incurred net losses in certain quarters since that time. We may not succeed in maintaining our profitability and could incur quarterly or annual losses in future periods. We intend to increase our expenses as we grow our business and expand into new geographic locations, and we expect to incur additional accounting, legal and other expenses associated with being a public company. If our revenue does not increase sufficiently to offset these increases in costs, our operating results will be harmed. Our historical operating results should not be considered as necessarily indicative of future operating results and we can provide no assurance that we will be able to maintain or increase our profitability in the future.

 

We may not recognize all revenue from our backlog or receive all payments anticipated under awarded projects and customer contracts.

 

As of March 31, 2010, we had backlog of approximately $635 million in future revenue under signed customer contracts for the installation or construction of projects, which we expect to be recognized over the period from 2010 to 2013, and we had been awarded, but not yet signed customer contracts for, projects with estimated total future revenue of an additional $618 million over the same period. As of March 31, 2009, we had backlog of approximately $260 million in future revenue under signed customer contracts for the installation or construction of projects, which we expected to be recognized over the period from 2009 to 2012, and we had been awarded, but not yet signed customer contracts for, projects with estimated total future revenue of an additional $926 million over the period from 2009 to 2013. We also expect to realize recurring revenue both under long-term O&M contracts and under long-term energy supply contracts for renewable energy plants that we own.

 

Our customers have the right under some circumstances to terminate contracts or defer the timing of our services and their payments to us. In addition, our government contracts are subject to the risks described below under “Provisions in government contracts may harm our business, financial condition and operating results.” The payment estimates for projects that have been awarded to us but for which we have not yet signed contracts have been prepared by management and are based upon a number of assumptions, including that the size and scope of the awarded projects will not change prior to the signing of customer contracts, that we or our customers will be able to obtain any necessary third-party financing for the awarded projects, and that we and our customers will reach agreement on and execute contracts for the awarded projects. We are not always able to enter into a contract for an awarded project on the terms proposed. As a result, we may not receive all of the revenue that we include in our backlog or that we estimate we will receive under awarded projects. If we do not receive all of the revenue we currently expect to receive, our future operating results will be adversely affected. In addition, a delay in the receipt of revenue, even if such revenue is eventually received, may cause our operating results for a particular quarter to fall below our expectations.

 

Our business is affected by seasonal trends and construction cycles, and these trends and cycles could have an adverse effect on our operating results.

 

We are subject to seasonal fluctuations and construction cycles, particularly in climates that experience colder weather during the winter months, such as the northern United States and Canada, or at educational institutions, where large projects are typically carried out during summer months when their facilities are unoccupied. In addition, government customers, many of which have fiscal years that do not coincide with ours, typically follow annual procurement cycles and appropriate funds on a fiscal-year basis even though contract performance may take more than one year. Further, government contracting cycles can be affected by the timing of, and delays in, the legislative process related to government programs and incentives that help drive demand for energy efficiency and renewable energy projects. As a result, our revenue and operating income in the third quarter are typically higher, and our revenue and operating income in the first quarter are typically lower, than in other quarters of the year. As a result of such fluctuations, we may occasionally experience declines in revenue or earnings as compared to the immediately preceding quarter, and comparisons of our operating results on a period-to-period basis may not be meaningful.

 

Our business depends in part on federal, state, provincial and local government support for energy efficiency and renewable energy, and a decline in such support could harm our business.

 

We depend in part on government legislation and policies that support energy efficiency and renewable energy projects and that enhance the economic feasibility of our energy efficiency services and small-scale renewable energy projects. The U.S. and Canadian federal governments and several of the states and provinces in which we operate support our existing and potential customers’ investments in energy efficiency and renewable energy through legislation and regulations that authorize and regulate the manner in which certain governmental entities do business with us, encourage or subsidize governmental procurement of our services, provide regulatory, tax and other incentives to others to procure our services and provide us with tax and other incentives that reduce our costs or increase our revenue.

 

For example, U.S. legislation authorizing federal agencies to enter into ESPCs, such as those we enter into with our customers, was enacted in 1992. In 2007, three years after the expiration of the original legislation, new ESPC legislation was enacted without an expiration provision, and in the same year, the President of the United States issued an executive order requiring federal agencies to set goals to reduce energy use and increase renewable energy sources and use. In addition, the American Recovery and Reinvestment Act of 2009 allocated $67 billion to promote clean energy, energy efficiency and advanced vehicles. Additionally, the Emergency Economic Stabilization Act of 2008 instituted the 1603 cash grant program, which may provide cash in lieu of an investment tax credit for eligible renewable energy generation sources for which construction commences prior to the end of 2010 where the project is placed in service by various dates set out in the act. The Internal Revenue Code, or the Code, currently provides production tax credits for the generation of electricity from wind projects and from LFG-fueled power projects, and an investment tax credit or grant in lieu of such tax credits for investments in LFG, wind, biomass and solar power generation projects. Various state and local governments have also implemented similar programs and incentives, including legislation authorizing the procurement of ESPCs.

 

We, our customers and prospective customers frequently depend on these programs to help justify the costs associated with, and to finance, energy efficiency and renewable energy projects. If any of these incentives are adversely amended, eliminated or not extended beyond their current expiration dates, or if funding for these incentives is reduced, it could adversely affect our ability to complete projects for existing customers and obtain project commitments from new customers. A delay or failure by government agencies to administer, or make procurements under, these programs in a timely and efficient manner could have a material adverse effect on our existing and potential customers’ willingness to enter into project commitments with us.

 

In addition, some of our customers purchase electricity, thermal energy or processed LFG from our renewable energy plants, or purchase other energy services from us, because tax, energy and environmental laws encourage or in some cases require these customers to procure power from renewable or low-emission sources, or to reduce their electricity use. Changes to these tax, energy and environmental laws could reduce our customers’ incentives and mandates to purchase the kinds of services that we supply, and could thereby adversely affect our business, financial condition and operating results.

 

Changes in the laws and regulations governing the public procurement of ESPCs could have a material impact on our business.

 

We derive a significant amount of our revenue from ESPCs with our government customers. While federal, state and local government rules governing such contracts vary, such rules may, for example, permit the funding of such projects through long-term financing arrangements; permit long-term payback periods from the savings realized through such contracts; allow units of government to exclude debt related to such projects from the calculation of their statutory debt limitation; allow for award of contracts on a “best value” instead of “lowest cost” basis; and allow for the use of sole source providers. To the extent these rules become more restrictive in the future, our business could be harmed.

 

A significant decline in the fiscal health of federal, state, provincial and local governments could reduce demand for our energy efficiency and renewable energy projects.

 

In 2009, approximately 85% of our revenue was derived from sales to federal, state, provincial or local governmental entities. A significant decline in the fiscal health of these existing and potential customers may make it difficult for them to enter into contracts for our services or to obtain financing necessary to fund such contracts, or may cause them to seek to renegotiate or terminate existing agreements with us.

 

Failure of third parties to manufacture quality products or provide reliable services in a timely manner could cause delays in the delivery of our services and completion of our projects, which could damage our reputation, have a negative impact on our relationships with our customers and adversely affect our growth.

 

Our success depends on our ability to provide services and complete projects in a timely manner, which in part depends on the ability of third parties to provide us with timely and reliable services and

products, such as boilers, chillers, cogeneration systems, PV panels, lighting and other complex components. In providing our services and completing our projects, we rely on products that meet our design specifications and components manufactured and supplied by third parties, as well as on services performed by subcontractors.

 

We rely on subcontractors to perform substantially all of the construction and installation work related to our projects. We provide all design and engineering work related to, and act as the general contractor for, our projects. We have established relationships with subcontractors that we believe to be reliable and capable of producing satisfactory results, but we often need to engage subcontractors with whom we have no experience for our projects. If any of our subcontractors are unable to provide services that meet or exceed our customers’ expectations or satisfy our contractual commitments, our reputation, business and operating results could be harmed.

 

The warranties provided by our third-party suppliers and subcontractors typically limit any direct harm we might experience as a result of our relying on their products and services. However, there can be no assurance that a supplier or subcontractor will be willing or able to fulfill its contractual obligations and make necessary repairs or replace equipment. In addition, these warranties generally expire within one to five years or may be of limited scope or provide limited remedies. If we are unable to avail ourselves of warranty protection, we may incur liability to our customers or additional costs related to the affected products and components, including replacement and installation costs, which could have a material adverse effect on our business, financial condition and operating results.

 

Moreover, any delays, malfunctions, inefficiencies or interruptions in these products or services — even if covered by warranties — could adversely affect the quality and performance of our solutions. This could cause us to experience difficulty retaining current customers and attracting new customers, and could harm our brand, reputation and growth. In addition, any significant interruption or delay by our suppliers in the manufacture or delivery of products or services on which we depend could require us to expend considerable time, effort and expense to establish alternate sources for such products and services.

 

We may have liability to our customers under our ESPCs if our projects fail to deliver the energy use reductions to which we are committed under the contract.

 

For our energy efficiency projects, we typically enter into ESPCs under which we commit that the projects will satisfy agreed-upon performance standards appropriate to the project. These commitments are typically structured as guarantees of increased energy efficiency that are based on the design, capacity, efficiency or operation of the specific equipment and systems we install. Our commitments generally fall into three categories: pre-agreed, equipment-level and whole building-level. Under a pre-agreed efficiency commitment, our customer reviews the project design in advance and agrees that, upon or shortly after completion of installation of the specified equipment comprising the project, the pre-agreed increase in energy efficiency will have been met. Under an equipment-level commitment, we commit to a level of increased energy efficiency based on the difference in use measured first with the existing equipment and then with the replacement equipment upon completion of installation. A whole building-level commitment requires measurement and verification of increased energy efficiency for a whole building, often based on readings of the utility meter where usage is measured. Depending on the project, the measurement and verification may be required only once, upon installation, based on an analysis of one or more sample installations, or may be required to be repeated at agreed upon intervals generally over periods of up to 20 years.

 

Under our contracts, we typically do not take responsibility for a wide variety of factors outside our control and exclude or adjust for such factors in commitment calculations. These factors include variations in energy prices and utility rates, weather, facility occupancy schedules, the amount of energy-using equipment in a facility, and failure of the customer to operate or maintain the project properly. We rely in part on warranties from our equipment suppliers and subcontractors to back-stop the warranties we provide to our customers and, where appropriate, pass on the warranties to our customers. However, the warranties we provide to our customers are sometimes broader in scope or longer in duration than the corresponding warranties we receive

from our suppliers and subcontractors, and we bear the risk for any differences, as well as the risk of warranty default by our suppliers and subcontractors.

 

Typically, our performance commitments apply to the aggregate overall performance of a project rather than to individual energy efficiency measures. Therefore, to the extent an individual measure underperforms, it may be offset by other measures that overperform. In the event that an energy efficiency project does not perform according to the agreed-upon specifications, our agreements typically allow us to satisfy our obligation by adjusting or modifying the installed equipment, installing additional measures to provide substitute energy savings, or paying the customer for lost energy savings based on the assumed conditions specified in the agreement. From our inception to March 31, 2010, our total payments to customers and incurred equipment replacement and maintenance costs under our energy efficiency commitments, after customer acceptance of a project, have been less than $100,000 in the aggregate. However, we may incur additional or increased liabilities or expenses under our ESPCs in the future. Such liabilities or expenses could be substantial, and they could materially harm our business, financial condition or operating results. In addition, any disputes with a customer over the extent to which we bear responsibility to improve performance or make payments to the customer may diminish our prospects for future business from that customer or damage our reputation in the marketplace.

 

We may assume responsibility under customer contracts for factors outside our control, including, in connection with some customer projects, the risk that fuel prices will increase.

 

We typically do not take responsibility under our contracts for a wide variety of factors outside our control. We have, however, in a limited number of contracts assumed some level of risk and responsibility for certain factors — sometimes only to the extent that variations exceed specified thresholds — and may also do so under certain contracts in the future, particularly in our contracts for renewable energy projects.

 

For example, under a contract for the construction and operation of a cogeneration facility at the U.S. Department of Energy Savannah River Site in South Carolina, a subsidiary of ours is exposed to the risk that the price of the biomass that will be used to fuel the cogeneration facility may rise during the 19-year performance period of the contract. Several provisions in that contract mitigate the price risk, including a specified annual increase in the price our subsidiary charges the customer for biomass fuel, incentives for the customer to make on-site biomass available to the cogeneration facility, an escrow fund from which our subsidiary can withdraw funds should the price of biomass in a given year exceed that charged to the customer, the right to reduce the amount of steam generated by the use of biomass to a stipulated minimum level and the ability to use other fuels, such as used tires, to produce up to 30% of the facility’s total production. In addition, although we typically structure our contracts so that our obligation to supply a customer with LFG, electricity or steam, for example, does not exceed the quantity produced by the production facility, in some circumstances we may commit to supply a customer with specified minimum quantities based on our projections of the facility’s production capacity. In such circumstances, if we are unable to meet such commitments, we may be required to incur additional costs or face penalties.

 

Despite the steps we have taken to mitigate risks under these and other contracts, such steps may not be sufficient to avoid the need to incur increased costs to satisfy our commitments, and such costs could be material. Increased costs that we are unable to pass through to our customers could have a material adverse effect on our operating results.

 

Our business depends on experienced and skilled personnel and substantial specialty subcontractor resources, and if we lose key personnel or if we are unable to attract and integrate additional skilled personnel, it will be more difficult for us to manage our business and complete projects.

 

The success of our business depends in large part on the skill of our personnel. Accordingly, it is critical that we maintain, and continue to build, a highly experienced management team and specialized workforce, including engineers, project and construction management, and business development and sales professionals. In addition, our construction projects require a significant amount of trade labor resources, such

as electricians, mechanics, carpenters, masons and other skilled workers, as well as certain specialty subcontractor skills.

 

Competition for personnel, particularly those with expertise in the energy services and renewable energy industries, is high, and identifying candidates with the appropriate qualifications can be costly and difficult. We may not be able to hire the necessary personnel to implement our business strategy given our anticipated hiring needs, or we may need to provide higher compensation or more training to our personnel than we currently anticipate.

 

In the event we are unable to attract, hire and retain the requisite personnel and subcontractors, we may experience delays in completing projects in accordance with project schedules and budgets, which may have an adverse effect on our financial results, harm our reputation and cause us to curtail our pursuit of new projects. Further, any increase in demand for personnel and specialty subcontractors may result in higher costs, causing us to exceed the budget on a project, which in turn may have an adverse effect on our business, financial condition and operating results and harm our relationships with our customers.

 

Our future success is particularly dependent on the vision, skills, experience and effort of our senior management team, including our executive officers and our founder, principal stockholder, president and chief executive officer, George P. Sakellaris. If we were to lose the services of any of our executive officers or key employees, our ability to effectively manage our operations and implement our strategy could be harmed and our business may suffer.

 

If we cannot obtain surety bonds and letters of credit, our ability to operate may be restricted.

 

Federal and state laws require us to secure the performance of certain long-term obligations through surety bonds and letters of credit. In addition, we are occasionally required to provide bid bonds or performance bonds to secure our performance under energy efficiency contracts. Our sureties have historically required that George P. Sakellaris, who is our founder, principal stockholder, president and chief executive officer, personally indemnify them for up to an aggregate of $50 million of losses associated with the bonds they have provided on our behalf. We expect this indemnity will terminate following the closing of this offering. In addition, in the event that Mr. Sakellaris no longer controls our company, our sureties may reevaluate our eligibility for surety bonds. Although we expect the net proceeds of this offering to increase our bonding capacity, our ability to obtain required bonds or letters of credit depends in large part upon our capitalization, working capital, past performance, management expertise and reputation, and external factors beyond our control, including the overall capacity of the surety market. Our ability to obtain letters of credit under our existing credit arrangements is limited. We are not permitted to have more than $10 million in letters of credit outstanding at any time (including letters of credit that have been drawn upon but not repaid on our behalf) under the terms of our revolving senior secured credit facility. Moreover, our use of letters of credit limits our borrowing capability under our revolving senior secured credit facility as the aggregate amount of letters of credit we have outstanding at any time reduces our borrowing capacity under the facility by an equal amount. As of March 31, 2010, we had no letters of credit outstanding.

 

In the future, we may have difficulty procuring or maintaining surety bonds or letters of credit, and obtaining them may become more expensive, require us to post cash collateral or otherwise involve unfavorable terms. Because we are sometimes required to have performance bonds or letters of credit in place before projects can commence or continue, our failure to obtain or maintain those bonds and letters of credit would adversely affect our ability to begin and complete projects, and thus could have a material adverse effect on our business, financial condition and operating results.

 

We operate in a highly competitive industry, and our current or future competitors may be able to compete more effectively than we do, which could have a material adverse effect on our business, revenue, growth rates and market share.

 

Our industry is highly competitive, with many companies of varying size and business models, many of which have their own proprietary technologies, competing for the same business as we do. Many of our competitors have longer operating histories and greater resources than us, and could focus their substantial

financial resources to develop a competing business model, develop products or services that are more attractive to potential customers than what we offer or convince our potential customers that they should require financing arrangements that would be impractical for smaller companies to offer. Our competitors may also offer energy solutions at prices below cost, devote significant sales forces to competing with us or attempt to recruit our key personnel by increasing compensation, any of which could improve their competitive positions. Any of these competitive factors could make it more difficult for us to attract and retain customers, cause us to lower our prices in order to compete, and reduce our market share and revenue, any of which could have a material adverse effect on our financial condition and operating results. We can provide no assurance that we will continue to effectively compete against our current competitors or additional companies that may enter our markets.

 

In addition, we may also face competition based on technological developments that reduce demand for electricity, increase power supplies through existing infrastructure or that otherwise compete with our products and services. We also encounter competition in the form of potential customers electing to develop solutions or perform services internally rather than engaging an outside provider such as us.

 

We may be unable to complete or operate our projects on a profitable basis or as we have committed to our customers.

 

Development, installation and construction of our energy efficiency and renewable energy projects, and operation of our renewable energy projects, entails many risks, including:

 

 

Any of these factors could give rise to construction delays and construction and other costs in excess of our expectations. This could prevent us from completing construction of our projects, cause defaults under our financing agreements or under contracts that require completion of project construction by a certain time, cause projects to be unprofitable for us, or otherwise impair our business, financial condition and operating results.

 

Our small-scale renewable energy plants may not generate expected levels of output.

 

The small-scale renewable energy plants that we construct and own are subject to various operating risks that may cause them to generate less than expected amounts of processed LFG, electricity or thermal energy. These risks include a failure or degradation of our, our customers’ or utilities’ equipment; an inability to find suitable replacement equipment or parts; less than expected supply of the plant’s source of renewable

energy, such as LFG or biomass; or a faster than expected diminishment of such supply. Any extended interruption in the plant’s operation, or failure of the plant for any reason to generate the expected amount of output, could have a material adverse effect on our business and operating results. In addition, we have in the past, and could in the future, incur material asset impairment charges if any of our renewable energy plants incurs operational issues that indicate that our expected future cash flows from the plant are less than its carrying value. Any such impairment charge could have a material adverse effect on our operating results in the period in which the charge is recorded.

 

We may be unable to manage our growth effectively.

 

Our business and operations have expanded rapidly in the last several years, and we anticipate that further expansion of our organization and operations will be required to achieve our expectations for future growth. In addition, in order to manage our expanding operations, we will also need to continue to improve our management, operational and financial controls and our reporting systems and procedures. All of these measures will require significant expenditures and will demand the attention of management. If we do not continue to enhance our management personnel and our operational and financial systems and controls in response to growth in our business, we could experience operating inefficiencies that could impair our competitive position and could increase our costs more than we had planned. If we are unable to manage growth effectively, our business, financial condition and operating results could be adversely affected.

 

We expect that some of our growth will be accomplished through the opening of new offices and the hiring of additional personnel to staff those offices. Even if an office is ultimately successful in generating additional revenue and profit for us, there is generally a lag of several years before we are able to recoup the expenses associated with opening that office.

 

In order to secure contracts for new projects, we typically face a long and variable selling cycle that requires significant resource commitments and requires a long lead time before we realize revenue.

 

The sales, design and construction process for energy efficiency and renewable energy projects typically takes from 12 to 36 months, with sales to federal government and housing authority customers tending to require the longest sales processes. Our existing and potential customers generally have extended budgeting and procurement processes, and sometimes must engage in regulatory approval processes, related to our services. Most of our potential customers issue a request for proposal, or RFP, as part of their consideration of alternatives for their proposed project. In preparation for responding to an RFP, we typically conduct a preliminary audit of the customer’s needs and the opportunity to reduce its energy costs. For projects involving a renewable energy plant that is not located on a customer’s site or that uses sources of energy not within the customer’s control, the sales process also involves the identification of sites with attractive sources of renewable energy, such as a landfill or a site with high winds, and it may involve obtaining necessary rights and governmental permits to develop a project on that site. If we are awarded a project, we then perform a more detailed audit of the customer’s facilities, which serves as the basis for the final specifications of the project. We then must negotiate and execute a contract with the customer. In addition, we or the customer typically need to obtain financing for the project.

 

This extended sales process requires the dedication of significant time by our sales and management personnel and our use of significant financial resources, with no certainty of success or recovery of our related expenses. A potential customer may go through the entire sales process and not accept our proposal. All of these factors can contribute to fluctuations in our quarterly financial performance and increase the likelihood that our operating results in a particular quarter will fall below investor expectations. These factors could also adversely affect our business, financial condition and operating results due to increased spending by us that is not offset by increased revenue.

 

Provisions in our government contracts may harm our business, financial condition and operating results.

 

A significant majority of our contract backlog and projects that have been awarded to us but have not yet been committed to signed contracts is attributable to customers that are government entities. Our contracts with the federal government and its agencies, and with state, provincial and local governments, customarily

contain provisions that give the government substantial rights and remedies, many of which are not typically found in commercial contracts, including provisions that allow the government to:

 

 

Generally, government contracts contain provisions permitting unilateral termination or modification, in whole or in part, at the government’s convenience. Under general principles of government contracting law, if the government terminates a contract for convenience, the terminated company may recover only its incurred or committed costs, settlement expenses and profit on work completed prior to the termination. If the government terminates a contract for default, the defaulting company is entitled to recover costs incurred and associated profits on accepted items only and may be liable for excess costs incurred by the government in procuring undelivered items from another source. In most of our contracts with the federal government, the government has agreed to make a payment to us in the event that it terminates the agreement early. The termination payment is designed to compensate us for the cost of construction plus financing costs and profit on the work completed.

 

In ESPCs for governmental entities, the methodologies for computing energy savings may be less favorable than for non-governmental customers and may be modified during the contract period. We may be liable for price reductions if the projected savings cannot be substantiated.

 

In addition to the right of the federal government to terminate its contracts with us, federal government contracts are conditioned upon the continuing approval by Congress of the necessary spending to honor such contracts. Congress often appropriates funds for a program on a September 30 fiscal-year basis even though contract performance may take more than one year. Consequently, at the beginning of many major governmental programs, contracts often may not be fully funded, and additional monies are then committed to the contract only if, as and when appropriations are made by Congress for future fiscal years. Similar practices are likely to also affect the availability of funding for our contracts with Canadian, as well as state, provincial and local, government entities. If one or more of our government contracts were terminated or reduced, or if appropriations for the funding of one or more of our contracts is delayed or terminated, our business, financial condition and operating results could be adversely affected.

 

Government contracts normally contain additional terms and conditions that may increase our costs of doing business, reduce our profits and expose us to liability for failure to comply with these terms and conditions. These include, for example:

 

 

Our contracts with Canadian governmental entities frequently involve similar risks. Any failure by us to comply with these governmental requirements could adversely affect our business.

 

Our renewable energy projects, particularly our LFG projects, depend on locating and acquiring suitable operating sites, of which there are a limited number.

 

Our small-scale renewable energy projects must be situated at sites that have access to renewable sources of energy. Specifically, LFG projects must originate on or near landfill sites, of which approximately 500 are currently available in the United States for economically viable LFG projects. Sites for our renewable energy plants must be suitable for construction and efficient operation, which, among other things, requires appropriate road access. Further, many plants must be interconnected to electricity transmission or distribution networks. Once we have identified a suitable operating site, obtaining the requisite LFG and/or land rights (including access rights, setbacks and other easements) requires us to negotiate with landowners and local government officials. These negotiations can take place over a long time, are not always successful and sometimes require economic concessions not in our original plans. The property rights necessary to construct and interconnect our plants must also be insurable and otherwise satisfactory to our financing counterparties. In addition, our ability to obtain adequate LFG and/or property rights is subject to competition. If a competitor or other party obtains LFG and/or land rights critical to our project development efforts and we are unable to reach agreement for their use, we could incur losses as a result of development costs for sites we do not develop, which we would have to write off. If we are unable to obtain adequate LFG and/or property or other rights for a renewable energy plant, including its interconnection, that plant may be smaller in size or potentially unfeasible. Failure to obtain insurable property rights for a project satisfactory to our financing sources would preclude our ability to obtain third-party financing and could prevent ongoing development and construction of that project.

 

We plan to expand our business in part through future acquisitions, but we may not be able to identify or complete suitable acquisitions.

 

Historically, acquisitions have been a significant part of our growth strategy. We plan to continue to use acquisitions of companies or assets to expand our project skill-sets and capabilities, expand our geographic markets, add experienced management and increase our product and service offerings. However, we may be unable to implement this growth strategy if we cannot identify suitable acquisition candidates, reach agreement with acquisition targets on acceptable terms or arrange required financing for acquisitions on acceptable terms. In addition, the time and effort involved in attempting to identify acquisition candidates and consummate acquisitions may divert members of our management from the operations of our company.

 

Any future acquisitions that we may make could disrupt our business, cause dilution to our stockholders and harm our business, financial condition or operating results.

 

If we are successful in consummating acquisitions, those acquisitions could subject us to a number of risks, including:

 

 

 

These factors could have a material adverse effect on our business, financial condition and operating results.

 

We need governmental approvals and permits, and we typically must meet specified qualifications, in order to undertake our energy efficiency projects and construct, own and operate our small-scale renewable energy projects, and any failure to do so would harm our business.

 

The design, construction and operation of our energy efficiency and small-scale renewable energy projects require various governmental approvals and permits, and may be subject to the imposition of related conditions that vary by jurisdiction. In some cases, these approvals and permits require periodic renewal. We cannot predict whether all permits required for a given project will be granted or whether the conditions associated with the permits will be achievable. The denial of a permit essential to a project or the imposition of impractical conditions would impair our ability to develop the project. In addition, we cannot predict whether the permits will attract significant opposition or whether the permitting process will be lengthened due to complexities and appeals. Delay in the review and permitting process for a project can impair or delay our ability to develop that project or increase the cost so substantially that the project is no longer attractive to us. We have experienced delays in developing our projects due to delays in obtaining permits and may experience delays in the future. If we were to commence construction in anticipation of obtaining the final, non-appealable permits needed for that project, we would be subject to the risk of being unable to complete the project if all the permits were not obtained. If this were to occur, we would likely lose a significant portion of our investment in the project and could incur a loss as a result. Further, the continued operations of our projects require continuous compliance with permit conditions. This compliance may require capital improvements or result in reduced operations. Any failure to procure, maintain and comply with necessary permits would adversely affect ongoing development, construction and continuing operation of our projects.

 

In addition, the projects we perform for governmental agencies are governed by particular qualification and contracting regimes. Certain states require qualification with an appropriate state agency as a precondition to performing work or appearing as a qualified energy service provider for state, county and local agencies within the state. For example, the Commonwealth of Massachusetts and the states of Colorado and Washington pre-qualify energy service providers and provide contract documents that serve as the starting point for negotiations with potential governmental clients. Most of the work that we perform for the federal government is performed under IDIQ agreements between a government agency and us or a subsidiary. These IDIQ agreements allow us to contract with the relevant agencies to implement energy projects, but no work may be performed unless we and the agency agree on a task order or delivery order governing the provision of a specific project. The government agencies enter into contracts for specific projects on a competitive basis. We and our subsidiaries and affiliates are currently party to an IDIQ agreement with the U.S. Department of Energy that expires in 2019. If we are unable to maintain or renew our IDIQ qualification under the U.S. Department of Energy program for ESPCs, or similar federal or state qualification regimes, our business could be materially harmed.

 

Many of our small-scale renewable energy projects are, and other future projects may be, subject to or affected by U.S. federal energy regulation or other regulations that govern the operation, ownership and sale of the facility, or the sale of electricity from the facility.

 

The Public Utility Holding Company Act of 2005, or PUHCA, and the Federal Power Act, or FPA, regulate public utility holding companies and their subsidiaries and place constraints on the conduct of their business. The FPA regulates wholesale sales of electricity and the transmission of electricity in interstate commerce by public utilities. Under the Public Utility Regulatory Policies Act of 1978, or PURPA, all of our current small-scale renewable energy projects are small power “qualifying facilities” (facilities meeting statutory size, fuel and ownership requirements) that are exempt from regulations under PUHCA, most provisions of the FPA and state rate regulation. None of our renewable energy projects are currently subject to rate regulation for wholesale power sales by the Federal Energy Regulatory Commission, or FERC, under the FPA, but certain of our projects that are under construction or development could become subject to such regulation in the future. Also, we may acquire interests in or develop generating projects that are not qualifying facilities. Non-qualifying facility projects would be fully subject to FERC corporate and rate regulation, and would be required to obtain FERC acceptance of their rate schedules for wholesale sales of energy, capacity and ancillary services, which requires substantial disclosures to and discretionary approvals from FERC. FERC may revoke or revise an entity’s authorization to make wholesale sales at negotiated, or market-based, rates if FERC determines that we can exercise market power in transmission or generation, create barriers to entry or engage in abusive affiliate transactions or market manipulation. In addition, many public utilities (including any non-qualifying facility generator in which we may invest) are subject to FERC reporting requirements that impose administrative burdens and that, if violated, can expose the company to civil penalties or other risks.

 

All of our wholesale electric power sales are subject to certain market behavior rules. These rules change from time to time, by virtue of FERC rulemaking proceedings and FERC-ordered amendments to utilities’ FERC tariffs. If we are deemed to have violated these rules, we will be subject to potential disgorgement of profits associated with the violation and/or suspension or revocation of our market-based rate authority, as well as potential criminal and civil penalties. If we were to lose market-based rate authority for any non-qualifying facility project we may acquire or develop in the future, we would be required to obtain FERC’s acceptance of a cost-based rate schedule and could become subject to, among other things, the burdensome accounting, record keeping and reporting requirements that are imposed on public utilities with cost-based rate schedules. This could have an adverse effect on the rates we charge for power from our projects and our cost of regulatory compliance.

 

Wholesale electric power sales are subject to increasing regulation. The terms and conditions for power sales, and the right to enter and remain in the wholesale electric sector, are subject to FERC oversight. Due to major regulatory restructuring initiatives at the federal and state levels, the U.S. electric industry has undergone substantial changes over the past decade. We cannot predict the future design of wholesale power markets or the ultimate effect ongoing regulatory changes will have on our business. Other proposals to further regulate the sector may be made and legislative or other attention to the electric power market restructuring process may delay or reverse the movement towards competitive markets.

 

If we become subject to additional regulation under PUHCA, FPA or other regulatory frameworks, if existing regulatory requirements become more onerous, or if other material changes to the regulation of the electric power markets take place, our business, financial condition and operating results could be adversely affected.

 

Compliance with environmental laws could adversely affect our operating results.

 

Costs of compliance with federal, state, provincial, local and other foreign existing and future environmental regulations could adversely affect our cash flow and profitability. We are required to comply with numerous environmental laws and regulations and to obtain numerous governmental permits in connection with energy efficiency and renewable energy projects, and we may incur significant additional costs to comply with these requirements. If we fail to comply with these requirements, we could be subject to

civil or criminal liability, damages and fines. Existing environmental regulations could be revised or reinterpreted and new laws and regulations could be adopted or become applicable to us or our projects, and future changes in environmental laws and regulations could occur. These factors may materially increase the amount we must invest to bring our projects into compliance and impose additional expense on our operations.

 

In addition, private lawsuits or enforcement actions by federal, state, provincial and/or foreign regulatory agencies may materially increase our costs. Certain environmental laws make us potentially liable on a joint and several basis for the remediation of contamination at or emanating from properties or facilities we currently or formerly owned or operated or properties to which we arranged for the disposal of hazardous substances. Such liability is not limited to the cleanup of contamination we actually caused. Although we seek to obtain indemnities against liabilities relating to historical contamination at the facilities we own or operate, we cannot provide any assurance that we will not incur liability relating to the remediation of contamination, including contamination we did not cause. For example, in 2009, a customer for which we were performing an energy efficiency project initiated a legal proceeding against us as a result of project delays that we believe were attributable to the discovery of hazardous materials and need for remediation by the customer. An adverse outcome in this proceeding could have an adverse effect on our operating results in the period in which the outcome is determined.

 

We may not be able to obtain or maintain, from time to time, all required environmental regulatory approvals. A delay in obtaining any required environmental regulatory approvals or failure to obtain and comply with them could adversely affect our business and operating results.

 

International expansion is one of our growth strategies, and international operations will expose us to additional risks that we do not face in the United States, which could have an adverse effect on our operating results.

 

We generate a significant portion of our revenue from operations in Canada, and although we are engaged in overseas projects for the U.S. Department of Defense, we currently derive a small amount of revenue from outside of North America. However, international expansion is one of our growth strategies, and we expect our revenue and operations outside of North America will expand in the future. These operations will be subject to a variety of risks that we do not face in the United States, and that we may face only to a limited degree in Canada, including:

 

 

Our overall success in international markets will depend, in part, on our ability to succeed in differing legal, regulatory, economic, social and political conditions. We may not be successful in developing and implementing policies and strategies that will be effective in managing these risks in each country where we

do business. Our failure to manage these risks successfully could harm our international operations, reduce our international sales and increase our costs, thus adversely affecting our business, financial condition and operating results.

 

Our insurance and contractual protections may not always cover lost revenue, increased expenses or liquidated damages payments.

 

Although we maintain insurance, obtain warranties from suppliers, obligate subcontractors to meet certain performance levels and attempt, where feasible, to pass risks we cannot control to our customers, the proceeds of such insurance, warranties, performance guarantees or risk sharing arrangements may not be adequate to cover lost revenue, increased expenses or liquidated damages payments that may be required in the future.

 

If the cost of energy generated by traditional sources does not increase, or if it decreases, demand for our services may decline.

 

Decreases in the costs associated with traditional sources of energy, such as prices for commodities like coal, oil and natural gas, may reduce demand for energy efficiency and renewable energy solutions. Technological progress in traditional forms of electricity generation or the discovery of large new deposits of traditional fuels could reduce the cost of electricity generated from those sources and as a consequence reduce the demand for our solutions. Any of these developments could have a material adverse effect on our business, financial condition and operating results.

 

We have a material weakness in our internal control over financial reporting. If we fail to establish and maintain proper and effective internal controls, our ability to produce accurate financial statements could be impaired, which could adversely affect our operating results, our ability to operate our business and investors’ and customers’ views of us.

 

As a public company, we will become subject to a set of laws and regulations requiring that we establish and maintain internal control over financial reporting. Internal control over financial reporting is defined under Securities and Exchange Commission, or SEC, rules as a process designed by, or under the supervision of, our principal executive and principal financial officers and effected by our board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. We have not yet begun the process of documenting, reviewing and, as appropriate, improving our internal controls and procedures in anticipation of being a public company and eventually becoming subject to the SEC rules concerning internal control over financial reporting, which take effect beginning with the filing of our second Annual Report on Form 10-K (which will be due in March 2012). Establishing and maintaining adequate internal financial and accounting controls and procedures so that we can produce accurate financial statements on a timely basis is a costly and time-consuming effort that needs to be re-evaluated frequently, and may distract our officers and employees from the operation of our business.

 

We do not currently have personnel with an appropriate level of knowledge, experience or training in the selection, application and implementation of GAAP as it relates to certain complex accounting issues, income taxes and SEC financial reporting requirements. This constitutes a material weakness in our internal control over financial reporting that could result in material misstatements in our financial statements not being prevented or detected. Although we plan to remediate this material weakness by hiring additional personnel with the requisite expertise, we may experience difficulties or delays in doing so, and new employees will require time and training to learn our business and operating processes and procedures.

 

If we fail to enhance and then maintain our internal control over financial reporting, we may be unable to report our financial results timely and accurately, and we may be less likely to prevent fraud. In addition, such failure could increase our operating costs, materially impair our ability to operate our business, result in SEC investigations and penalties and lead to the delisting of our common stock from the New York Stock Exchange, or NYSE. The resulting damage to our reputation in the marketplace and our financial

credibility could significantly impair our sales and marketing efforts with customers. Further, investors’ perceptions that our internal controls are inadequate or that we are unable to produce accurate financial statements could adversely affect the market price of our Class A common stock.

 

Changes in utility regulation and tariffs could adversely affect our business.

 

Our business is affected by regulations and tariffs that govern the activities of utilities. For example, utility companies are commonly allowed by regulatory authorities to charge fees to larger industrial customers for disconnecting from the electric grid or for having the capacity to use power from the electric grid for back-up purposes. These fees could increase the cost to our customers of taking advantage of our services and make them less desirable, thereby harming our business, financial condition and operating results. Our current generating projects are all operated as qualifying facilities. FERC regulations under the FPA confer upon these facilities key rights to interconnection with local utilities, and can entitle qualifying facilities to enter into power purchase agreements with local utilities, from which the qualifying facilities benefit. Changes to these federal laws and regulations could increase our regulatory burdens and costs, and could reduce our revenue. In addition, modifications to the pricing policies of utilities could require renewable energy systems to achieve lower prices in order to compete with the price of electricity from the electric grid and may reduce the economic attractiveness of certain energy efficiency measures.

 

Some of the demand-reduction services we provide for utilities and institutional clients are subject to regulatory tariffs imposed under federal and state utility laws. In addition, the operation of, and electrical interconnection for, our renewable energy projects are subject to federal, state or provincial interconnection and federal reliability standards that are also set forth in utility tariffs. These tariffs specify rules, business practices and economic terms to which we are subject. The tariffs are drafted by the utilities and approved by the utilities’ state and federal regulatory commissions. These tariffs change frequently and it is possible that future changes will increase our administrative burden or adversely affect the terms and conditions under which we render service to our customers.

 

Our activities and operations are subject to numerous health and safety laws and regulations, and if we violate such regulations, we could face penalties and fines.

 

We are subject to numerous health and safety laws and regulations in each of the jurisdictions in which we operate. These laws and regulations require us to obtain and maintain permits and approvals and implement health and safety programs and procedures to control risks associated with our projects. Compliance with those laws and regulations can require us to incur substantial costs. Moreover, if our compliance programs are not successful, we could be subject to penalties or to revocation of our permits, which may require us to curtail or cease operations of the affected projects. Violations of laws, regulations and permit requirements may also result in criminal sanctions or injunctions.

 

Health and safety laws, regulations and permit requirements may change or become more stringent. Any such changes could require us to incur materially higher costs than we currently have. Our costs of complying with current and future health and safety laws, regulations and permit requirements, and any liabilities, fines or other sanctions resulting from violations of them, could adversely affect our business, financial condition and operating results.

 

Our credit facilities and debt instruments contain financial and operating restrictions that may limit our business activities and our access to credit.

 

Provisions in our credit facilities and debt instruments impose restrictions on our and certain of our subsidiaries’ ability to, among other things:

 

 

 

These agreements also contain other customary covenants, including covenants that require us to meet specified financial ratios and financial tests. We may not be able to comply with these covenants in the future. Our failure to comply with these covenants may result in the declaration of an event of default and cause us to be unable to borrow under our credit facilities and debt instruments. In addition to preventing additional borrowings under these agreements, an event of default, if not cured or waived, may result in the acceleration of the maturity of indebtedness outstanding under these agreements, which would require us to pay all amounts outstanding. If an event of default occurs, we may not be able to cure it within any applicable cure period, if at all. If the maturity of our indebtedness is accelerated, we may not have sufficient funds available for repayment or we may not have the ability to borrow or obtain sufficient funds to replace the accelerated indebtedness on terms acceptable to us or at all.

 

If our subsidiaries default on their obligations under their debt instruments, we may need to make payments to lenders to prevent foreclosure on the collateral securing the debt.

 

We typically set up subsidiaries to own and finance our renewable energy projects. These subsidiaries incur various types of debt which can be used to finance one or more projects. This debt is typically structured as non-recourse debt, which means it is repayable solely from the revenue from the projects financed by the debt and is secured by such projects’ physical assets, major contracts and cash accounts and a pledge of our equity interests in the subsidiaries involved in the projects. Although our subsidiary debt is typically non-recourse to Ameresco, if a subsidiary of ours defaults on such obligations, or if one project out of several financed by a particular subsidiary’s indebtedness encounters difficulties or is terminated, then we may from time to time determine to provide financial support to the subsidiary in order to maintain rights to the project or otherwise avoid the adverse consequences of a default. In the event a subsidiary defaults on its indebtedness, its creditors may foreclose on the collateral securing the indebtedness, which may result in our losing our ownership interest in some or all of the subsidiary’s assets. The loss of our ownership interest in a subsidiary or some or all of a subsidiary’s assets could have a material adverse effect on our business, financial condition and operating results.

 

We are exposed to the credit risk of some of our customers.

 

Most of our revenue is derived under multi-year or long-term contracts with our customers, and our revenue is therefore dependent to a large extent on the creditworthiness of our customers. During periods of economic downturn in the global economy, our exposure to credit risks from our customers increases, and our efforts to monitor and mitigate the associated risks may not be effective in reducing our credit risks. In the event of non-payment by one or more of our customers, our business, financial condition and operating results could be adversely affected.

 

The use and enjoyment of real property rights for our small-scale renewable energy projects may be adversely affected by the rights of lienholders and leaseholders that are superior to those of the grantors of those real property rights to us.

 

Our small-scale renewable energy projects generally are, and are likely to continue to be, located on land we or our customers occupy pursuant to long-term easements and leases. The ownership interests in the land subject to these easements and leases may be subject to mortgages securing loans or other liens (such as tax liens) and other easement and lease rights of third parties (such as leases of oil or mineral rights) that were created prior to our or our customers’ easements and leases. As a result, the rights under these easements or leases may be subject, and subordinate, to the rights of those third parties. We typically perform title searches and obtain title insurance to protect ourselves or our customers against these risks. Such measures may, however, be inadequate to protect against all risk of loss of rights to use the land on which these projects are located, which could have a material adverse effect on our business, financial condition and operating results.

 

Fluctuations in foreign currency exchange rates can impact our results.

 

A significant portion of our total revenue is generated by our Canadian subsidiary, Ameresco Canada. Changes in exchange rates between the Canadian dollar and the U.S. dollar may adversely affect our operating results.

 

The trading price of our Class A common stock is likely to be volatile, and you may not be able to sell your shares at or above the initial public offering price.

 

Our Class A common stock has no prior trading history. The initial public offering price for our Class A common stock was determined through negotiations between us and the representatives of the underwriters. This price does not necessarily reflect the price at which investors in the market will be willing to buy and sell shares of our Class A common stock following this offering. In addition, the trading price of our Class A common stock is likely to be highly volatile and could be subject to wide fluctuations in response to various factors. In addition to the risks described in this section, factors that may cause the market price of our Class A common stock to fluctuate include:

 

 

In addition, if the stock market in general experiences a significant decline, the trading price of our Class A common stock could decline for reasons unrelated to our business, financial condition or operating results.

 

Some companies that have had volatile market prices for their securities have had securities class actions filed against them. If a suit were filed against us, regardless of its merits or outcome, it would likely result in substantial costs and divert management’s attention and resources. This could have a material adverse effect on our business, operating results and financial condition.

 

Our securities have no prior market and an active public trading market for our Class A common stock may not develop.

 

Prior to this offering, there has been no public market for shares of our Class A common stock. Although our Class A common stock has been approved for listing on the NYSE, an active public trading market for our Class A common stock may not develop or, if it develops, may not be maintained after this offering. For example, applicable NYSE rules impose certain securities trading requirements, including minimum trading price, minimum number of stockholders and minimum market capitalization. If an active

public trading market for our Class A common stock does not develop or is not sustained, it may be difficult for you to sell your shares of our Class A common stock at an attractive price or at all.

 

Holders of our Class A common stock, which is the stock we are selling in this offering, are entitled to one vote per share, and holders of our Class B common stock are entitled to five votes per share. The lower voting power of our Class A common stock may negatively affect the attractiveness of our Class A common stock to investors and, as a result, its market value.

 

We have two classes of common stock: Class A common stock, which is the stock we are selling in this offering and which is entitled to one vote per share, and Class B common stock, which is entitled to five votes per share. The difference in the voting power of our Class A and Class B common stock could diminish the market value of our Class A common stock because of the superior voting rights of our Class B common stock and the power those rights confer.

 

For the foreseeable future, Mr. Sakellaris or his affiliates will be able to control the selection of all members of our board of directors, as well as virtually every other matter that requires stockholder approval, which will severely limit the ability of other stockholders to influence corporate matters.

 

Except in certain limited circumstances required by applicable law, holders of Class A and Class B common stock vote together as a single class on all matters to be voted on by our stockholders. Immediately following the closing of this offering, Mr. Sakellaris, our founder, principal stockholder, president and chief executive officer will own all of our Class B common stock, which, together with his Class A common stock, will represent 82.9% of the combined voting power of our outstanding Class A and Class B common stock. Under our restated certificate of incorporation, holders of shares of Class B common stock may generally transfer those shares to family members, including spouses and descendents or the spouses of such descendents, as well as to affiliated entities, without having the shares automatically convert into shares of Class A common stock. Therefore, Mr. Sakellaris, his affiliates, and his family members and descendents will, for the foreseeable future, be able to control the outcome of the voting on virtually all matters requiring stockholder approval, including the election of directors and significant corporate transactions such as an acquisition of our company, even if they come to own, in the aggregate, as little as 20% of the economic interest of the outstanding shares of our Class A and Class B common stock. Moreover, these persons may take actions in their own interests that you or our other stockholders do not view as beneficial. See “Principal and Selling Stockholders” and “Description of Capital Stock.”

 

Future sales of shares by existing stockholders could cause our stock price to decline.

 

Once a trading market develops for our Class A common stock, many of our stockholders for the first time will have an opportunity to sell their shares, subject to the contractual lock-up agreements and other restrictions on resale discussed in this prospectus. Sales by our existing stockholders of a substantial number of shares in the public market, or the threat that substantial sales might occur, could cause the market price of the Class A common stock to decrease significantly. These factors could also make it difficult for us to raise additional capital by selling our Class A common stock. See “Shares Eligible for Future Sale” for further details regarding the number of shares eligible for sale in the public market after this offering.

 

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline.

 

The trading market for our Class A common stock will depend in part on any research reports that securities or industry analysts publish about us or our business. After this offering, if no securities or industry analysts initiate coverage of our company, the trading price for our Class A common stock may be negatively impacted. In the event securities or industry analysts cover our company and one or more of these analysts downgrade our stock or publish unfavorable reports about our business, our stock price would likely decline. In addition, if any securities or industry analysts cease coverage of our company or fail to publish reports on us regularly, demand for our Class A common stock could decrease, which could cause our stock price and trading volume to decline.

 

You will experience substantial dilution as a result of this offering and future equity issuances.

 

The initial public offering price per share of our Class A common stock is substantially higher than the pro forma net tangible book value per share of our Class A common stock. As a result, investors purchasing Class A common stock in this offering will experience immediate dilution of $6.47 per share. In addition, we have granted options to acquire Class A common stock at prices significantly below the initial public offering price. To the extent outstanding options are exercised, there will be further dilution to investors in this offering. See “Dilution.”

 

Our management will have broad discretion over the use of the proceeds we receive in this offering and might not apply the proceeds in ways that increase the value of your investment.

 

We expect to use a portion of the net proceeds to us from this offering to repay the balance outstanding under our $50 million revolving senior secured credit facility, under which $24.9 million in principal was outstanding at of March 31, 2010 and $31.4 million in principal was outstanding as of June 30, 2010, and the entire principal balance of and all accrued and unpaid interest on the $3.0 million subordinated note held by Mr. Sakellaris, our founder, principal stockholder, president and chief executive officer. We intend to use the balance of the net proceeds for working capital and other general corporate purposes, which may include opening additional offices in the United States and abroad, expanding sales and marketing activities, funding the development and construction of our small-scale renewable energy projects and other capital expenditures. Our management will have broad discretion over the use of the net proceeds from this offering, and you will be relying on the judgment of our management regarding the application of those net proceeds. Although it is the intention of our management to use the net proceeds from the offering in the best interests of the company, our management might not apply the net proceeds from this offering in ways that increase the value of your investment or in ways with which you agree. See “Use of Proceeds.”

 

We do not anticipate paying any cash dividends on our capital stock in the foreseeable future.

 

We have never declared or paid any cash dividends on our capital stock and do not currently expect to pay any cash dividends for the foreseeable future. Our revolving senior secured credit facility with Bank of America limits our ability to declare and pay cash dividends during the term of that agreement. See “Dividend Policy.” We intend to use our future earnings, if any, in the operation and expansion of our business. Accordingly, you are not likely to receive any dividends on your Class A common stock for the foreseeable future, and your ability to achieve a return on your investment will therefore depend on appreciation in the market price of our Class A common stock.

 

Anti-takeover provisions in our charter documents and Delaware law could discourage, delay or prevent a change in control of our company and may affect the trading price of our Class A common stock.

 

We are a Delaware corporation and the anti-takeover provisions of the Delaware General Corporation Law may discourage, delay or prevent an acquisition of our company by prohibiting us from engaging in a business combination with an interested stockholder for a period of three years after the person becomes an interested stockholder, even if a change in control would be supported by our existing stockholders. In addition, our restated certificate of incorporation and by-laws may discourage, delay or prevent an acquisition or a change in our management that stockholders may consider favorable. Our restated certificate of incorporation and by-laws:

This prospectus contains forward-looking statements. All statements other than statements of historical facts contained in this prospectus, including statements regarding our strategy, future operations, future financial position, future revenue, projected costs, prospects, plans, objectives of management and expected market growth are forward-looking statements. These statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

 

The words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “plan,” “predict,” “project,” “will,” “would” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. These forward-looking statements include, among other things, statements about:

 

 

These forward looking statements are only predictions and we may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements, so you should not place undue reliance on our forward-looking statements. Actual results or events could differ materially from the plans, intentions and expectations disclosed in the forward-looking statements we make. We have based these forward-looking statements largely on our current expectations and projections about future events and trends that we believe may affect our business, financial condition and operating results. We have included important factors in the cautionary statements included in this prospectus, particularly in the “Risk Factors” section, that could cause actual future results or events to differ materially from the forward-looking statements that we make. Our forward-looking statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint ventures or investments we may make.

 

The forward-looking statements in this prospectus represent our views as of the date of this prospectus. We anticipate that subsequent events and developments will cause our views to change. However, while we may elect to update these forward-looking statements at some point in the future, we have no current intention of doing so except to the extent required by applicable law. You should, therefore, not rely on these forward-looking statements as representing our views as of any date subsequent to the date of this prospectus.

 

This prospectus also contains estimates and other statistical data made by independent parties and by us relating to market size and growth and other data about our industry. We obtained the industry and market data in this prospectus from our own research as well as from industry and general publications, surveys and studies conducted by third parties, some of which may not be publicly available. For example, Frost & Sullivan’s 2008 report entitled North American Energy Management Services — Investment Analysis, which we refer to in this prospectus, is available to the public for a fee. Such data involves a number of assumptions and limitations and contains projections and estimates of the future performance of the industries in which we operate that are subject to a high degree of uncertainty. We caution you not to give undue weight to such projections, assumptions and estimates. While we believe that these publications, studies and surveys are reliable, we have not independently verified the data contained in them.

 

We estimate that we will receive net proceeds from this offering of approximately $53.6 million, after deducting the underwriting discount and estimated offering expenses payable by us. The selling stockholders will receive $25.1 million from their sale of our Class A common stock in this offering, after deducting the underwriting discount. We will not receive any proceeds from the sale of shares by the selling stockholders; however, we will receive an aggregate of $1.8 million from the exercise of stock options being exercised by selling stockholders in connection with this offering.

 

We intend to use the net proceeds we receive from this offering as follows:

 

 

We may use a portion of the net proceeds that we receive from this offering to expand our current business through acquisitions of complementary companies, assets or technologies. Although we are engaged in discussions with respect to a potential acquisition for consideration of less than $10 million, we currently have no understandings, commitments or agreements to make any acquisitions.

 

Pending specific utilization of the net proceeds as described above, we intend to invest the net proceeds of the offering in short-term investment grade and U.S. government securities.

 

Bank of America, N.A., an affiliate of Merrill, Lynch, Pierce, Fenner & Smith Incorporated, an underwriter of this offering, is acting as the agent and a lender under our revolving senior secured credit facility. See “Underwriting — Conflicts of Interest.”

 

We have never declared or paid any cash dividends on our capital stock. We currently intend to retain earnings, if any, to finance the growth and development of our business and do not expect to pay any cash dividends for the foreseeable future. Our revolving senior secured credit facility with Bank of America contains provisions that limit our ability to declare and pay cash dividends during the term of that agreement. Payment of future dividends, if any, will be at the discretion of our board of directors and will depend on our financial condition, results of operations, capital requirements, restrictions contained in current or future financing instruments, provisions of applicable law and other factors our board of directors deems relevant.

 

The following table sets forth our cash and cash equivalents and capitalization as of March 31, 2010:

 

 

You should read this table together with our consolidated financial statements and the related notes appearing at the end of this prospectus and the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section of this prospectus.

 

 

The table above excludes:

 

 

If you invest in our Class A common stock in this offering, your interest in our company will be diluted immediately to the extent of the difference between the initial public offering price per share of our Class A common stock and the pro forma as adjusted net tangible book value per share of our Class A and Class B common stock after this offering. Our pro forma net tangible book value as of March 31, 2010 was $87.1 million, or $2.57 per share of our Class A and Class B common stock. Our pro forma net tangible book value per share set forth below represents our total tangible assets less total liabilities and convertible preferred stock, divided by the number of shares of our Class A and Class B common stock outstanding on March 31, 2010, after giving effect to (i) our issuance of 405,286 shares of Class A common stock upon the June 2010 exercise of a warrant at an exercise price of $0.005 per share; (ii) a two-for-one split of our common stock, (iii) the reclassification of all outstanding shares of our common stock as Class A common stock, (iv) the conversion of all shares of our convertible preferred stock, other than those held by Mr. Sakellaris, into shares of our Class A common stock, (v) the conversion of all other outstanding shares of our convertible preferred stock into shares of our Class B common stock and (vi) the issuance of 932,500 shares of our Class A common stock upon the exercise of vested stock options by the selling stockholders in connection with this offering at a weighted-average exercise price of $1.94.

 

After giving effect to our issuance and sale of 6,000,000 shares of Class A common stock in this offering, and after deducting the underwriting discount and estimated offering expenses payable by us, and the application of the net proceeds to us as described under “Use of Proceeds,” the pro forma as adjusted net tangible book value as of March 31, 2010 would have been $140.7 million, or $3.53 per share of Class A and Class B common stock. This represents an immediate increase in net tangible book value to existing stockholders of $0.96 per share of Class A and Class B common stock. New investors who purchase shares of Class A common stock in this offering will suffer an immediate dilution of their investment of $6.47 per share. Dilution per share to new investors is determined by subtracting the pro forma as adjusted net tangible book value per share of our Class A and Class B common stock after this offering from the initial public offering price per share of our Class A common stock paid by a new investor. The following table illustrates this per share dilution to new investors purchasing shares of Class A common stock in this offering:

 

 

If the underwriters exercise their over-allotment option in full, the pro forma as adjusted net tangible book value will increase to $3.68 per share of Class A and Class B common stock, representing an immediate increase in net tangible book value to existing stockholders of $1.11 per share of Class A and Class B common stock and an immediate dilution of $6.32 per share of Class A common stock to new investors. If any shares of our Class A common stock are issued upon exercise of outstanding options, new investors will experience further dilution (see below in this section for additional information).

 

The following table summarizes, on a pro forma basis as of March 31, 2010 (giving effect to (i) our issuance of 405,286 shares of Class A common stock upon the June 2010 exercise of a warrant at an exercise price of $0.005 per share; (ii) a two-for-one split of our common stock, (iii) the reclassification of all outstanding shares of our common stock as Class A common stock, (iv) the conversion of all shares of our convertible preferred stock, other than those held by Mr. Sakellaris, into shares of our Class A common stock, (v) the conversion of all other outstanding shares of our convertible preferred stock into shares of our Class B common stock and (vi) the issuance of 932,500 shares of our Class A common stock upon the exercise of vested stock options by the selling stockholders in connection with this offering at a weighted-average exercise price of $1.94) the differences between the number of shares of common stock purchased from us, the total consideration paid to us, and the average price per share paid by existing stockholders and by new investors purchasing shares of our Class A common stock from us in this offering. The calculation below is based on the initial public offering price of $10.00, before the deduction of the underwriting discount and estimated offering expenses payable by us.

 

 

The number of shares of common stock purchased from us prior to this offering by existing stockholders is based on 15,880,070 shares of our Class A common stock and 18,000,000 shares of our Class B common stock outstanding as of March 31, 2010 after giving effect to (i) our issuance of 405,286 shares of Class A common stock upon the June 2010 exercise of a warrant at an exercise price of $0.005 per share, (ii) a two-for-one split of our common stock, (iii) the reclassification of all outstanding shares of our common stock as Class A common stock, (iv) the conversion of all shares of our convertible preferred stock, other than those held by Mr. Sakellaris, into shares of our Class A common stock, (v) the conversion of all other outstanding shares of our convertible preferred stock into shares of Class B common stock and (vi) the issuance of 932,500 shares of our Class A common stock upon the exercise of vested stock options by the selling stockholders in connection with this offering at a weighted-average exercise price of $1.94, and excludes:

 

 

To the extent that any of the outstanding options are exercised, there will be further dilution to new investors. To the extent that all of such outstanding options had been exercised as of March 31, 2010, the pro forma net tangible book value of our Class A and Class B common stock would be $2.64 per share, the pro forma as adjusted net tangible book value of our Class A and Class B common stock after this offering would be $3.42 per share, and total dilution to new investors in shares of Class A common stock would be $6.58 per share. If all options outstanding as of March 31, 2010 had been exercised in full, new investors would have contributed 68% of the total consideration paid for our Class A and Class B common stock outstanding but would own only 12% of our Class A and Class B common stock outstanding after the offering.

 

The sale of 2,696,820 shares of Class A common stock by the selling stockholders in this offering will reduce the number of shares held by existing stockholders to 31,183,250, or 78% of the total shares of our Class A and Class B common stock outstanding, and will increase the number of shares held by new investors to 8,696,820, or 22% of the total shares of our Class A and Class B common stock outstanding. If the

underwriters exercise their over-allotment option in full, the number of shares held by existing stockholders will further decrease to 30,923,250, or 76% of the total shares of our Class A and Class B common stock outstanding, and the number of shares held by new investors will further increase to 10,001,343, or 24% of the total shares of our Class A and Class B common stock outstanding.

 

The following tables summarize our consolidated financial data for the periods presented.

Our management uses adjusted EBITDA:

 

 

We understand that, although measures similar to adjusted EBITDA are frequently used by investors and securities analysts in their evaluation of companies, adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for GAAP operating income or an analysis of our results of operations as reported under GAAP. Some of these limitations are:

Overview

 

Ameresco is a leading provider of energy efficiency solutions for facilities throughout North America. We provide solutions that enable customers to reduce their energy consumption, lower their operating and maintenance costs and realize environmental benefits. Our comprehensive set of services includes upgrades to a facility’s energy infrastructure and the construction and operation of small-scale renewable energy plants.

 

We report results under ASC 280 for four segments: U.S. federal, central U.S. region, other U.S. regions and Canada. Each segment provides customers with energy efficiency and renewable energy solutions. These segments do not include results of other activities, such as O&M and sales of renewable energy and certain other renewable energy products, that are managed centrally at our corporate headquarters, or corporate operating expenses not specifically allocated to the segments. See Note 19 to our consolidated financial statements appearing at the end of this prospectus.

 

Our revenue has increased from $20.9 million in 2001, our first full year of operations, to $428.5 million in 2009. We achieved profitability in 2002, and we have been profitable every year since then.

 

In addition to organic growth, strategic acquisitions of complementary businesses and assets have been an important part of our development. Since inception, we have completed more than ten acquisitions, which have enabled us to broaden our service offerings and expand our geographical reach. Our acquisition of the energy services business of Duke Energy in 2002 expanded our geographical reach into Canada and the southeastern United States and enabled us to penetrate the federal government market for energy efficiency projects. The acquisition of the energy services business of Exelon in 2004 expanded our geographical reach into the Midwest. Our acquisition of the energy services business of Northeast Utilities in 2006 substantially grew our capability to provide services for the federal market and in Europe. Our acquisition of Southwestern Photovoltaics, Inc. in 2007 significantly expanded our offering of solar energy products and services.

 

Energy Savings Performance and Energy Supply Contracts

 

For our energy efficiency projects, we typically enter into ESPCs under which we agree to develop, design, engineer and construct a project and also commit that the project will satisfy agreed-upon performance standards that vary from project to project. These performance commitments are typically based on the design, capacity, efficiency or operation of the specific equipment and systems we install. Our commitments generally fall into three categories: pre-agreed, equipment-level and whole building-level. Under a pre-agreed energy reduction commitment, our customer reviews the project design in advance and agrees that, upon or shortly after completion of installation of the specified equipment comprising the project, the commitment will have been met. Under an equipment-level commitment, we commit to a level of energy use reduction based on the difference in use measured first with the existing equipment and then with the replacement equipment. A whole building-level commitment requires demonstration of energy usage reduction for a whole building, often based on readings of the utility meter where usage is measured. Depending on the project, the measurement and demonstration may be required only once, upon installation, based on an analysis of one or more sample installations, or may be required to be repeated at agreed upon intervals generally over up to 20 years.

 

Under our contracts, we typically do not take responsibility for a wide variety of factors outside our control and exclude or adjust for such factors in commitment calculations. These factors include variations in energy prices and utility rates, weather, facility occupancy schedules, the amount of energy-using equipment in a facility, and failure of the customer to operate or maintain the project properly. Typically, our performance commitments apply to the aggregate overall performance of a project rather than to individual energy efficiency measures. Therefore, to the extent an individual measure underperforms, it may be offset by other measures that overperform. In the event that an energy efficiency project does not perform according to the agreed-upon specifications, our agreements typically allow us to satisfy our obligation by adjusting or modifying the installed equipment, installing additional measures to provide substitute energy savings, or paying the customer for lost energy savings based on the assumed conditions specified in the agreement. Many of our equipment supply, local design, and installation subcontracts contain provisions that enable us to seek recourse against our vendors or subcontractors if there is a deficiency in our energy reduction commitment. From our inception to March 31, 2010, our total payments to customers and incurred equipment replacement and maintenance costs under our energy reduction commitments, after customer acceptance of a project, have been less than $100,000 in the aggregate. See “Risk Factors — We may have liability to our customers under our ESPCs if our projects fail to deliver the energy use reductions to which we are committed under the contract.”

 

Payments by the federal government for energy efficiency measures are based on the services provided and the products installed, but are limited to the savings derived from such measures, calculated in accordance with federal regulatory guidelines and the specific contract’s terms. The savings are typically determined by comparing energy use and other costs before and after the installation of the energy efficiency measures, adjusted for changes that affect energy use and other costs but are not caused by the energy efficiency measures.

 

For projects involving the construction of a small-scale renewable energy plant that we own and operate, we enter into long-term contracts to supply the electricity, processed LFG, heat or cooling generated by the plant to the customer, which is typically a utility, municipality, industrial facility or other large purchaser of energy. The rights to use the site for the plant and purchase of renewable fuel for the plant are also obtained by us under long-term agreements with terms at least as long as the associated output supply agreement. Our supply agreements typically provide for fixed prices or prices that escalate at a fixed rate or vary based on a market benchmark. See “Risk Factors — We may assume responsibility under customer contracts for factors outside our control, including, in connection with some customer projects, the risk that fuel prices will increase.”

 

Project Financing

 

To finance projects with federal governmental agencies, we typically sell to the lenders our right to receive a portion of the long-term payments from the customer arising out of the project for a purchase price reflecting a discount to the aggregate amount due from the customer. The purchase price is generally advanced to us over the implementation period based on completed work or a schedule predetermined to coincide with the construction of the project. Under the terms of these financing arrangements, we are required to complete the construction or installation of the project in accordance with the contract with our customer, and the debt remains on our consolidated balance sheet until the completed project is accepted by the customer. Once the completed project is accepted by the customer, the financing is treated as a true sale and the related receivable and financing liability are removed from our consolidated balance sheet.

 

Institutional customers, such as state, provincial and local governments, schools and public housing authorities, typically finance their energy efficiency and renewable energy projects through either tax-exempt leases or issuances of municipal bonds. We assist in the structuring of such third-party financing.

 

In some instances, customers prefer that we retain ownership of the renewable energy plants and related project assets that we construct for them. In these projects, we typically enter into a long-term supply agreement to furnish electricity, gas, heat or cooling to the customer’s facility. To finance the significant upfront capital costs required to develop and construct the plant, we rely either on our internal cash flow or, in some cases, third-party debt. For project financing by third-party lenders, we typically establish a separate

subsidiary, usually a limited liability company, to own the project assets and related contracts. The subsidiary contracts with us for construction and operation of the project and enters into a financing agreement directly with the lenders. Additionally, we will provide assurance to the lender that the project will achieve commercial operation. Although the financing is secured by the assets of the subsidiary and a pledge of our equity interests in the subsidiary, and is non-recourse to Ameresco, we may from time to time determine to provide financial support to the subsidiary in order to maintain rights to the project or otherwise avoid the adverse consequences of a default. The amount of such financing is included on our consolidated balance sheet.

 

In addition to project-related debt, we currently maintain a $50 million revolving senior secured credit facility with a commercial bank to finance our working capital needs.

 

Effects of Seasonality

 

We are subject to seasonal fluctuations and construction cycles, particularly in climates that experience colder weather during the winter months, such as the northern United States and Canada, or at educational institutions, where large projects are typically carried out during summer months when their facilities are unoccupied. In addition, government customers, many of which have fiscal years that do not coincide with ours, typically follow annual procurement cycles and appropriate funds on a fiscal-year basis even though contract performance may take more than one year. Further, government contracting cycles can be affected by the timing of, and delays in, the legislative process related to government programs and incentives that help drive demand for energy efficiency and renewable energy projects. As a result, our revenue and operating income in the third quarter are typically higher, and our revenue and operating income in the first quarter are typically lower, than in other quarters of the year. As a result of such fluctuations, we may occasionally experience declines in revenue or earnings as compared to the immediately preceding quarter, and comparisons of our operating results on a period-to-period basis may not be meaningful.

 

Our annual and quarterly financial results are also subject to significant fluctuations as a result of other factors, many of which are outside our control. See “Risk Factors — Our operating results may fluctuate significantly from quarter to quarter and may fall below expectations in any particular fiscal quarter.”

 

Backlog and Awarded Projects

 

As of March 31, 2010, we had backlog of approximately $635 million in future revenue under signed customer contracts for the installation or construction of projects, which we expect to be recognized over the period from 2010 to 2013, and we had been awarded, but not yet signed customer contracts for, projects with estimated total future revenue of an additional $618 million over the same period. As of March 31, 2009, we had backlog of approximately $260 million in future revenue under signed customer contracts for the installation or construction of projects, which we expected to be recognized over the period from 2009 to 2012, and we had been awarded, but not yet signed customer contracts for, projects with estimated total future revenue of an additional $926 million over the period from 2009 to 2013. As of December 31, 2009, we had backlog of approximately $590 million in future revenue under signed customer contracts for the installation or construction of projects, which we expect to be recognized over the period from 2010 to 2013, and we had been awarded, but not yet signed customer contracts for, projects with estimated total future revenue of an additional $700 million over the same period. As of December 31, 2008, we had backlog of approximately $263 million in future revenue under signed customer contracts for the installation or construction of projects, which we expected to be recognized over the period from 2009 to 2011, and we had been awarded, but not yet signed customer contracts for, projects with estimated total future revenue of an additional $939 million over the period from 2009 to 2013. We also expect to realize recurring revenue both under long-term O&M contracts and under energy supply contracts for renewable energy plants that we own. See “Risk Factors — We may not recognize all revenue from our backlog or receive all payments anticipated under awarded projects and customer contracts.”

 

Financial Operations Overview

 

Revenue

 

We derive revenue from energy efficiency and renewable energy products and services. Our energy efficiency products and services include the design, engineering and installation of equipment and other measures to improve the efficiency and control the operation of a facility’s energy infrastructure. Our renewable energy products and services include the construction of small-scale plants that produce electricity, gas, heat or cooling from renewable sources of energy, the sale of such electricity, processed LFG, heat or cooling from plants that we own, and the sale and installation of solar energy products and systems.

 

While in any particular quarter a single customer may account for more than ten percent of revenue, in 2007, 2008 and 2009, no customer accounted for more than ten percent of our revenue. During the quarter ended March 31, 2010, one customer, the U.S. Department of Energy, Savannah River Site, accounted for 14.1% of our total revenue for the quarter.

 

Direct Expenses and Gross Margin

 

Direct expenses include the cost of labor, materials, equipment, subcontracting and outside engineering that are required for the development and installation of our projects, as well as preconstruction costs, sales incentives, associated travel, inventory obsolescence charges, and, if applicable, costs of procuring financing. A majority of our contracts have fixed price terms; however, in some cases we negotiate protections, such as a cost-plus structure, to mitigate the risk of rising prices for materials, services and equipment.

 

Direct expenses also include O&M costs for the small-scale renewable energy plants that we own, including the cost of fuel (if any) and depreciation charges.

 

Gross margin, which is gross profit as a percent of revenue, is affected by a number of factors, including the type of services performed and the geographic region in which the sale is made. Renewable energy projects that we own and operate typically have higher margins than energy efficiency projects, and sales in the United States typically have higher margins than in Canada due to the typical mix of products and services that we sell there.

 

Operating Expenses

 

Operating expenses consist of salaries and benefits, project development costs, and general, administrative and other expenses.

 

Salaries and benefits. Salaries and benefits consist primarily of expenses for personnel not directly engaged in specific project or revenue generating activity. These expenses include the time of executive management, legal, finance, accounting, human resources, information technology and other staff not utilized in a particular project. We employ a comprehensive time card system which creates a contemporaneous record of the actual time by employees on project activity. We expect salaries and benefits to increase as we incur additional costs related to operating as a publicly-traded company, including accounting, compliance and legal.

 

Project development costs. Project development costs consist primarily of sales, engineering, legal, finance and third-party expenses directly related to the development of a specific customer opportunity. This also includes associated travel and marketing expenses. We intend to hire additional sales personnel and initiate additional marketing programs as we expand into new regions or complement existing development resources. Accordingly, we expect that our project development costs will continue to increase, but will moderate as a percentage of revenue over time.

 

General, administrative and other expenses. These expenses consist primarily of rents and occupancy, professional services, insurance, unallocated travel expenses, telecommunications and office expenses. Professional services consist principally of recruiting costs, external legal, audit, tax and other consulting services. We expect general and administrative expenses to increase as we incur additional costs related to operating as a publicly-traded company, including increased audit and legal fees, costs of compliance with

securities, corporate governance and other regulations, investor relations expenses and higher insurance premiums, particularly those related to director and officer insurance.

 

Other Income (Expense), net

 

Other income (expense), net consists primarily of interest income on cash balances, interest expense on borrowings and amortization of deferred financing costs, unrealized gains and losses on derivatives not accounted for as hedges, and realized gains on derivatives not accounted for as hedges. Interest expense will vary periodically depending on the amounts drawn on our revolving senior secured credit facility and the prevailing short-term interest rates.

 

Provision for Income Taxes.

 

The provision for income taxes is based on various rates set by federal and local authorities and is affected by permanent and temporary differences between financial accounting and tax reporting requirements.

 

Critical Accounting Policies and Estimates

 

This discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expense and related disclosures. The most significant estimates with regard to these consolidated financial statements relate to estimates of final contract profit in accordance with long-term contracts, project development costs, project assets, impairment of goodwill, impairment of long-lived assets, fair value of derivative financial instruments, income taxes and stock-based compensation expense. Such estimates and assumptions are based on historical experience and on various other factors that management believes to be reasonable under the circumstances. Estimates and assumptions are made on an ongoing basis, and accordingly, the actual results may differ from these estimates under different assumptions or conditions.

 

The following critical accounting policies, among others, affect our more significant judgments and estimates used in the preparation of our consolidated financial statements.

 

Revenue Recognition

 

For each arrangement we have with a customer, we typically provide a combination of one or more of the following services or products:

 

 

Often, we will sell a combination of these services and products in a bundled arrangement. We divide bundled arrangements into separate deliverables and revenue is allocated to each deliverable based on the relative fair market value of all the elements. The fair market value is determined based on the price of the deliverable sold on a stand-alone basis.

 

We recognize revenue from the installation or construction of a project on a percentage-of-completion basis. The percentage-of-completion for each project is determined on an actual cost-to-estimated final cost basis. In accordance with industry practice, we include in current assets and liabilities the amounts of receivables related to construction projects that are payable over a period in excess of one year. We recognize

revenue associated with contract change orders only when the authorization for the change order has been properly executed and the work has been performed and accepted by the customer.

 

When the estimate on a contract indicates a loss, or claims against costs incurred reduce the likelihood of recoverability of such costs, our policy is to record the entire expected loss immediately, regardless of the percentage of completion.

 

Deferred revenue represents circumstances where (i) there has been a receipt of cash from the customer for work or services that have yet to be performed, (ii) receipt of cash where the product or service may not have been accepted by the customer or (iii) when all other revenue recognition criteria have been met, but an estimate of the final total cost cannot be determined. Deferred revenue will vary depending on the timing and amount of cash receipts from customers and can vary significantly depending on specific contractual terms. As a result, deferred revenue is likely to fluctuate from period to period. Unbilled receivables represent amounts earned and billable that were not invoiced at the end of the fiscal period.

 

We recognize revenue from the sale and delivery of products, including the output of our renewable energy plants, when produced and delivered to the customer, in accordance with the specific contract terms, provided that persuasive evidence of an arrangement exists, our price to the customer is fixed or determinable and collectibility is reasonably assured.

 

We recognize revenue from O&M contracts and consulting services as the related services are performed.

 

For a limited number of contracts under which we receive additional revenue based on a share of energy savings, we recognize such additional revenue as energy savings are generated.

 

Project Development Costs

 

We capitalize as project development costs only those costs incurred in connection with the development of energy efficiency and renewable energy projects, primarily direct labor, interest costs, outside contractor services, consulting fees, legal fees and associated travel, if incurred after a point in time when the realization of related revenue becomes probable. Project development costs incurred prior to the probable realization of revenue are expensed as incurred.

 

Project Assets

 

We capitalize interest costs relating to construction financing during the period of construction. The interest capitalized is included in the total cost of the project at completion. The amount of interest capitalized for the years ended December 31, 2007, 2008 and 2009 were $0, $0.2 million and $1.4 million, respectively, and for the first quarters of 2009 and 2010 were $0.3 million and $0.3 million respectively.

 

Routine maintenance costs are expensed in the current year’s consolidated statements of income and comprehensive income to the extent that they do not extend the life of the asset. Major maintenance, upgrades and overhauls are required for certain components of our assets. In these instances, the costs associated with these upgrades are capitalized and are depreciated over the shorter of the life of the asset or until the next required major maintenance or overhaul period. Gains or losses on disposal of property and equipment are reflected in general and administrative expenses in the consolidated statements of income and comprehensive income.

 

We evaluate our long-lived assets for impairment as events or changes in circumstances indicate the carrying value of these assets may not be fully recoverable. We evaluate recoverability of long-lived assets to be held and used by estimating the undiscounted future cash flows before interest associated with the expected uses and eventual disposition of those assets. When these comparisons indicate that the carrying value of those assets is greater than the undiscounted cash flows, we recognize an impairment loss for the amount that the carrying value exceeds the fair value.

 

During 2008, we determined that impairment had occurred on two of our LFG energy facilities. One facility’s landfill owner was experiencing permanent operational issues with its existing well field equipment.

The volume of LFG supplied to our facility was impaired by this factor, resulting in a write-down of the asset value. The second facility’s industrial customer filed for bankruptcy in 2008. We assessed the likelihood of the industrial customer emerging from bankruptcy and the resulting impact on future cash flows to the project in determining the amount of the impairment. A total of $3.5 million was written down for these two facilities, and is included in direct expenses in the accompanying consolidated statement of income and comprehensive income for 2008.

 

During 2007, we decommissioned one of our LFG facilities as the supply agreement with the local utility company expired in December 2006. During 2007, the plant was temporarily shut down. The plant equipment had been in service for 20 years and the cost of maintaining the aged equipment was economically unfeasible. The remaining book value of $2.0 million was written off, and is included in direct expenses in the accompanying consolidated statement of income and comprehensive income for 2007.

 

Impairment of Goodwill

 

We apply ASC Topic 350 in accounting for the valuation of goodwill and identifiable intangible assets. During our annual goodwill impairment tests at December 31, 2009, 2008 and 2007, we determined that the fair value of equity exceeded the carrying value of equity, and therefore that goodwill was not impaired.

 

Goodwill represents the excess of cost over the fair value of net tangible and identifiable intangible assets of businesses acquired. We assess the impairment of goodwill and intangible assets with indefinite lives on an annual basis and whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. We would record an impairment charge if such an assessment were to indicate that, more likely than not, the fair value of such assets was less than their carrying values. Judgment is required in determining whether an event has occurred that may impair the value of goodwill or identifiable intangible assets. Factors that could indicate that an impairment may exist include significant underperformance relative to plan or long-term projections, significant changes in business strategy, significant negative industry or economic trends or a significant decline in the base stock price of our public competitors for a sustained period of time.

 

The first step, or Step 1, of the goodwill impairment test, used to identify potential impairment, compares the fair value of the equity with its carrying amount, including goodwill. If the fair value of the equity exceeds its carrying amount, goodwill of the reporting unit is considered not impaired, thus the second step of the impairment test is unnecessary. If the carrying amount of a reporting unit exceeds its fair value, the second step of the goodwill impairment test shall be performed to measure the amount of impairment loss, if any. We performed a Step 1 test at our December 31, 2009, 2008 and 2007 annual testing dates and determined that the fair value of equity exceeded the carrying value of equity, and therefore that goodwill was not impaired.

 

We completed the Step 1 test using both an income approach and a market approach. The discounted cash flow method was used to measure the fair value of our equity under the income approach. A terminal value utilizing a constant growth rate of cash flows was used to calculate a terminal value after the explicit projection period. Determining the fair value using a discounted cash flow method requires that we make significant estimates and assumptions, including long-term projections of cash flows, market conditions and appropriate discount rates. Our judgments are based upon historical experience, current market trends, pipeline for future sales and other information. While we believe that the estimates and assumptions underlying the valuation methodology are reasonable, different estimates and assumptions could result in a different outcome. In estimating future cash flows, we rely on internally-generated projections for a defined time period for sales and operating profits, including capital expenditures, changes in net working capital and adjustments for non-cash items to arrive at the free cash flow available to invested capital.

 

Under the market approach, we estimate the fair value based on market multiples of revenue and earnings of comparable publicly-traded companies and comparable transactions of similar companies. The estimates and assumptions used in our calculations include revenue growth rates, expense growth rates, expected capital expenditures to determine projected cash flows, expected tax rates and an estimated discount

rate to determine present value of expected cash flows. These estimates are based on historical experiences, our projections of future operating activity and our weighted-average cost of capital.

 

In addition, we periodically review the estimated useful lives of our identifiable intangible assets, taking into consideration any events or circumstances that might result in either a diminished fair value or revised useful life. If the Step 1 test concludes an impairment is indicated, we will employ a second step to measure the impairment. If we determine that an impairment has occurred, we will record a write-down of the carrying value and charge the impairment as an operating expense in the period the determination is made. Although we believe goodwill and intangible assets are appropriately stated in our consolidated financial statements, changes in strategy or market conditions could significantly impact these judgments and require an adjustment to the recorded balance.

 

Impairment of Long-Lived Assets

 

We periodically evaluate long-lived assets for events and circumstances that indicate a potential impairment. A review of long-lived assets for impairment is performed whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate. Each impairment test is based on a comparison of the estimated undiscounted cash flows of the asset as compared to the recorded value of the asset. If these estimates or their related assumptions change in the future, an impairment charge may be required against these assets in the reporting period in which the impairment is determined.

 

Derivative Financial Instruments

 

We account for our interest rate swaps as derivative financial instruments in accordance with the related guidance. Under this guidance, derivatives are carried on our consolidated balance sheet at fair value. The fair value of our interest rate swaps is determined based on observable market data in combination with expected cash flows for each instrument.

 

Effective January 1, 2009, we adopted new guidance which expands the disclosure requirements for derivative instruments and hedging activities.

 

In the normal course of business, we utilize derivative contracts as part of our risk management strategy to manage exposure to market fluctuations in interest rates. These instruments are subject to various credit and market risks. Controls and monitoring procedures for these instruments have been established and are routinely reevaluated. Credit risk represents the potential loss that may occur because a party to a transaction fails to perform according to the terms of the contract. The measure of credit exposure is the replacement cost of contracts with a positive fair value. We seek to manage credit risk by entering into financial instrument transactions only through counterparties that we believe to be creditworthy. Market risk represents the potential loss due to the decrease in the value of a financial instrument caused primarily by changes in interest rates. We seek to manage market risk by establishing and monitoring limits on the types and degree of risk that may be undertaken. As a matter of policy, we do not use derivatives for speculative purposes.

 

We are exposed to interest rate risk through our borrowing activities. A portion of our project financing includes three projects that utilize a variable rate swap instrument. Prior to December 31, 2009, we entered into two 15-year interest rate swap contracts under which we agreed to pay an amount equal to a specified fixed rate of interest times a notional principal amount, and to, in turn, receive an amount equal to a specified variable rate of interest times the same notional principal amount. During the three months ended March 31, 2010, we entered into a 14-year interest rate swap contract under which we agreed to pay an amount equal to a specified fixed rate of interest times a notional principal amount, and to in turn receive an amount equal to a specified variable rate of interest times the same notional principal amount. We entered into the interest rate swap contracts as an economic hedge.

 

We recognize all derivatives in our consolidated financial statements at fair value.

The interest rate swaps that we entered into prior to December 31, 2009, qualify, but have not been designated, as fair value hedges. As such, any changes in fair value are reported in other income (expense) in our consolidated statements of income and comprehensive income. Cash flows from these derivative instruments are reported as operating activities on the consolidated statements of cash flows.

 

The interest rate swap that we have entered into during 2010 does qualify, and has been designated, as a fair value hedge. We recognize the fair value of this derivative instrument in our consolidated balance sheets and any changes in the fair value are recorded as adjustments to other comprehensive income (loss).

 

With respect to our interest rate swaps, we recorded the unrealized gain (loss) in earnings in 2007, 2008, 2009 and the first quarter of 2010 of approximately $(1.4 million), $(2.8 million), $2.3 million and $(0.1 million), respectively, as other (expense) income in our consolidated statements of income and comprehensive income.

 

Income Taxes

 

We provide for income taxes based on the liability method. We provide for deferred income taxes based on the expected future tax consequences of differences between the financial statement basis and the tax basis of assets and liabilities calculated using the enacted tax rates in effect for the year in which the differences are expected to be reflected in the tax return.

 

We account for uncertain tax positions using a “more-likely-than-not” threshold for recognizing and resolving uncertain tax positions. The evaluation of uncertain tax positions is based on factors that include, but are not limited to, changes in tax law, the measurement of tax positions taken or expected to be taken in tax returns, the effective settlement of matters subject to audit, new audit activity and changes in facts or circumstances related to a tax position. We evaluate uncertain tax positions on a quarterly basis and adjust the level of the liability to reflect any subsequent changes in the relevant facts surrounding the uncertain positions. Our liabilities for an uncertain tax position can be relieved only if the contingency becomes legally extinguished through either payment to the taxing authority or the expiration of the statute of limitations, the recognition of the benefits associated with the position meet the “more-likely-than-not” threshold or the liability becomes effectively settled through the examination process. We consider matters to be effectively settled once: the taxing authority has completed all of its required or expected examination procedures, including all appeals and administrative reviews; we have no plans to appeal or litigate any aspect of the tax position; and we believe that it is highly unlikely that the taxing authority would examine or re-examine the related tax position. We also accrue for potential interest and penalties, related to unrecognized tax benefits in income tax expense.

 

Business Segments

 

We report four segments: U.S. federal, central U.S. region, other U.S. regions and Canada. Each segment provides customers with energy efficiency and renewable energy solutions. The other U.S. regions segment is an aggregation of three regions: northeast U.S., southeast U.S. and southwest U.S. These regions have similar economic characteristics — in particular, expected and actual gross profit margins. In addition, they sell products and services of a similar nature, serve similar types of customers and use similar methods to distribute their products and services. Accordingly, these three regions meet the aggregation criteria set forth in ASC 280. The “all other” category includes activities, such as O&M and sales of renewable energy and certain other renewable energy products, that are managed centrally at our corporate headquarters. It also includes all corporate operating expenses not specifically allocated to the segments. We do not allocate any indirect expenses to the segments.

 

Stock-Based Compensation Expense

 

Our stock-based compensation expense results from the issuances of shares of restricted common stock and grants of stock options and warrants to employees, directors, outside consultants and others. We recognize the costs associated with option and warrant grants using the fair value recognition provisions of ASC 718, Compensation — Stock Compensation (formerly SFAS No. 123(R), Share-Based Payment).

Generally, ASC 718 requires the value of all stock-based payments to be recognized in the statement of operations based on their estimated fair value at date of grant amortized over the grants’ vesting period.

 

Grants of Restricted Shares

 

On October 25, 2006, we issued 2,000,000 shares of restricted stock to George P. Sakellaris, our founder, principal shareholder, president and chief executive officer under the 2000 stock plan in consideration for his personal indemnity of surety arrangements required for certain projects. The shares vested in full upon the date three years from the date of grant. At the time the shares were issued, the fair value was determined to be $3.41 per share. We recorded an expense of $2.3 million, $2.3 million and $1.9 million in 2007, 2008 and 2009, respectively, related to this award. This expense is included in salaries and benefits in our consolidated statements of income and comprehensive income.

 

Issuance of Warrants

 

As part of a financing agreement, we issued warrants to acquire 2,000,000 and 1,600,000 shares of common stock in 2001 and 2002, respectively. The warrants initially had a per share exercise price of $0.005 and $0.30, respectively; however, the $0.30 per share exercise price was subsequently reduced to $0.005. During 2008, we repurchased 3,194,714 of these warrants at an average price of $2.505 per share, for a total price of $8.0 million. We recorded this transaction in additional paid-in capital and it is reflected in our consolidated balance sheets for 2008 and 2009. In June 2010, we issued 405,286 shares of Class A common stock upon the exercise of a warrant at an exercise price of $0.005 per share, and no warrants to purchase shares of our common stock remain outstanding.

 

Stock Option Grants

 

We have granted stock options to certain employees and directors under the 2000 stock plan. At March 31, 2010, 8,897,850 shares were available for grant under the 2000 stock plan.

 

Under the terms of the 2000 stock plan, all options expire if not exercised within ten years after the grant date. The options vest over five years, with 20% vesting at the end of the first year and five percent vesting every three months beginning one year after the grant date. If the employee ceases to be employed for any reason before vested options have been exercised, the employee generally has three months to exercise vested options or they are forfeited.

 

Effective January 1, 2006, we adopted the fair value recognition provisions of ASC 718 requiring that all stock-based payments to employees, including grants of employee stock options and modifications to existing stock options, be recognized in the consolidated statements of income and comprehensive income based on their fair values, using the prospective-transition method.

 

Effective with the adoption of ASC 718, we elected to use the Black-Scholes option pricing model to determine the weighted-average fair value of options granted.

 

The determination of the fair value of stock-based payment awards utilizing the Black-Scholes model is affected by the stock price and a number of assumptions, including expected volatility, expected life, risk-free interest rate and expected dividends. The following table sets forth the significant assumptions used in the model during 2007, 2008 and 2009:

 

 

We will continue to use our judgment in evaluating the expected term, volatility and forfeiture rate related to our own stock-based compensation on a prospective basis, and incorporating these factors into the

Black-Scholes pricing model. Higher volatility and longer expected lives result in an increase to stock-based compensation expense determined at the date of grant. In addition, any changes in the estimated forfeiture rate can have a significant effect on reported stock-based compensation expense, as the cumulative effect of adjusting the rate for all expense amortization is recognized in the period that the forfeiture estimate is changed. If a revised forfeiture rate is higher than the previously estimated forfeiture rate, an adjustment is made that will result in a decrease to the stock-based compensation expense recognized in our consolidated financial statements. If a revised forfeiture rate is lower than the previously estimated rate, an adjustment is made that will result in an increase to the stock-based compensation expense recognized in our consolidated financial statements. These expenses will affect our direct expenses, project development and marketing expenses, and salaries and benefits expense.

 

As of March 31, 2010 we had $6.3 million of total unrecognized stock-based compensation cost related to employee stock options. We expect to recognize this cost over a weighted-average period of 3.8 years after March 31, 2010. The allocation of this expense between direct expenses, project development and marketing expenses, and salaries and benefits expense will depend on the salaries and work assignments of the personnel holding these options.

 

Determination of Fair Value

 

We believe we have used reasonable methodologies and assumptions in determining the fair value of our common stock for financial reporting purposes. Our board of directors has historically estimated the fair value of our common stock. Because there has been no public market for our shares, our board of directors historically determined the fair value of our common stock based primarily on the market approach, together with a number of objective and subjective factors, including:

 

 

The market approach estimates the fair value of a company by applying market multiples of publicly-traded, or recently-acquired, firms in the same or similar lines of business to the results and projected results of the company being valued. In establishing exercise prices for our options, we followed a methodology designed to result in exercise prices that were not lower than, but could be higher than, the then fair value of our common stock. When choosing companies for use in the market approach, we focused on companies that provide energy efficiency services and have high rates of growth. To determine our enterprise value, we reviewed the multiple of market valuations of the comparable companies to their adjusted EBITDA for the prior fiscal year (based on publicly-available data), as well as the multiples of adjusted EBITDA for the prior fiscal year paid by us for our acquisitions. Based on this review, we established a market multiple which was generally higher than that of our comparable companies, and which we then applied to our own adjusted EBITDA for the prior fiscal year. To determine equity value, we added cash on hand at the end of the period and the cash from the pro forma exercise of stock options, and then subtracted senior corporate debt. The resulting value was divided by the number of common shares outstanding on a fully diluted basis to obtain the fair value per share of common stock. Typically, we performed a new valuation annually after completing our audited consolidated financial statements.

 

We used adjusted EBITDA in determining our enterprise value under the market approach because we believe that metric provides greater comparability than other metrics for the companies included in the analysis. We considered using net income, book value and cash flow; however, we found those metrics less meaningful than adjusted EBITDA due to varying levels of non-cash and non-operating income and expenses, and the effects of leverage, in the other companies’ financial statements. We believe adjusted EBITDA was the most meaningful financial metric for purposes of estimating the fair value of our common stock for financial statement reporting purposes because it is an unlevered measure of operating earnings potential before financing and certain other accounting decisions are considered. In addition to the use of the market approach to determine the enterprise value, we considered the discounted cash flow methodology to estimate the equity

value in the goodwill impairment analysis discussed on page F-11. The resulting equity values obtained from the discounted cash flow methodology corroborated the results of the market approach used in our contemporaneous common stock valuations.

 

Since the beginning of 2007, we granted stock options with exercise prices as follows:

 

 

The analyses undertaken in determining the exercise prices for all option grants between January 24, 2007 and December 31, 2009 are summarized below.

 

Grants on January 24, 2007. On October 25, 2006, our board of directors established the exercise price per share of common stock at $3.41 per share. The market approach resulted in an enterprise value of $144.6 million, determined by applying the market multiple to our adjusted EBITDA for the year ended December 31, 2005. That value was increased by cash on hand totaling $11.8 million and reduced by debt of $10.5 million, for an equity value of $145.9 million. The equity value was divided by 42.8 million fully diluted shares outstanding to arrive at the estimated fair value per share.

 

Grants from July 25, 2007 to January 30, 2008. On July 25, 2007, our board of directors established the exercise price per share of common stock at $4.22 per share. The market approach resulted in an enterprise value of $157.9 million, determined by applying the market multiple to our adjusted EBITDA for the year ended December 31, 2006. That value was increased by cash on hand totaling $45.5 million and reduced by debt of $8.0 million, for an equity value of $195.3 million. The equity value was divided by 46.2 million fully diluted shares outstanding to arrive at the estimated fair value per share.

 

Grants from April 30, 2008 to January 28, 2009. On April 30, 2008, our board of directors established the exercise price per share of common stock at $6.055 per share. The market approach resulted in an enterprise value of $223.6 million, determined by applying the market multiple to our adjusted EBITDA for the year ended December 31, 2007. That value was increased by cash on hand totaling $45.5 million and reduced by debt of $8.0 million. In view of the increase in the number of options outstanding, we added the pro forma exercise cash value of the options, at a weighted-average exercise price of $1.995 per share, totaling $21.7 million. This resulted in an equity value of $280.7 million, which was divided by 46.4 million fully diluted shares outstanding to arrive at the estimated fair value per share.

 

Grants from July 22, 2009 to September 30, 2009. On July 22, 2009, our board of directors established the exercise price per share of common stock at $6.055 per share. Based on the methodology described above, our board would have decreased the value of a share of our common stock (from $6.055 to $5.66). However, the decrease was due primarily to higher corporate debt levels and a lower cash balance, which in our board’s view were the result primarily of the unprecedented economic conditions prevailing at that time. Our board, therefore, determined not to reduce its estimate of the fair value of the common stock and to maintain the value at $6.055 per share.

 

In March 2010, in connection with the preparation of our consolidated financial statements for the year ended December 31, 2009 and in preparing for our initial public offering, our board of directors decided to undertake a reassessment of the fair value of our common stock in 2007, 2008 and 2009. As a part of that reassessment, our board of directors took into account not only the factors it originally considered in determining fair value, but it also considered as of such dates:

 

 

 

In performing this retrospective analysis, we reexamined and reapplied the market approach and also applied the current value method to allocate the equity to the various share classes as outlined in the American Institute of Certified Public Accountants Technical Practice Aid, Valuation of Privately-Held Company Equity Securities Issued as Compensation, which we refer to as the practice aid. We believe that the valuation methodologies used in the retrospective analysis are reasonable and consistent with the practice aid.

 

In applying the current value method, we considered the rights of our Series A convertible preferred stock, which we refer to as our Series A preferred stock, and which will be converted into shares of Class B common stock upon the closing of this offering. The calculated enterprise value as of each of the valuation dates was significantly higher than the cumulative liquidation preference of our Series A preferred stock of $3.2 million. We also determined that in each valuation date, the Series A preferred stock would receive a substantially higher per share value on an “as if” converted to common stock basis than by retaining its liquidation preference. Thus for the purposes of these valuations the total equity value was divided by the fully diluted shares outstanding in order to calculate the per share value of our common stock.

 

In connection with this retrospective analysis, in determining our enterprise value, our analysis also considered the calculated multiple of market valuations of the comparable companies to their next 12 months adjusted EBITDA, and applied this multiple to our own next 12 months projected adjusted EBITDA, in addition to considering the enterprise value to trailing 12 months adjusted EBITDA, with more weight placed on our projected EBITDA analysis than the historical adjusted EBITDA analysis. To determine equity value, we added cash on hand at the end of the period and the cash from the assumed pro forma exercise of in-the-money stock options, and then subtracted senior corporate debt. To allocate the equity, we considered the option pricing method from the practice aid. In connection with applying the option pricing method to value our common stock for these valuation dates, we determined that allocating the equity based on applying the option pricing method instead of the current value method in the contemporaneous valuations resulted in immaterial differences from the per share value calculated using the current value method.

 

Following this retrospective analysis, our board of directors determined that the fair value of our common stock remained as previously determined in 2007, 2008 and on January 28, 2009, and that the fair value was $9.00 per share on July 22, 2009 and $11.00 per share on September 25, 2009, as described below.

 

January 28, 2009 Fair Value Calculation. The fair value of our common stock as of January 28, 2009 was retrospectively determined to be $6.055 per share. In applying the market approach, our next 12 months projected adjusted EBITDA was primarily affected by the following factors:

 

 

July 22, 2009 Fair Value Calculation. The fair value of our common stock as of July 22, 2009 was retrospectively determined to be $9.00 per share. The primary reason for the significant increase in the valuation of our common stock between January 28, 2009 and July 22, 2009 was the 11% increase in our next

12 months projected adjusted EBITDA between those two dates. Our projected adjusted EBITDA in July 2009 had increased significantly for the following reasons:

 

 

The valuation of our common stock in July 2009 was also significantly affected by an increase, between January 2009 and July 2009, in the multiple of market valuations of comparable companies that we applied to our next 12 months projected adjusted EBITDA. The multiple we applied in this analysis in January 2009, derived from publicly available data on the comparable companies we used in the market approach, was eight. We increased the multiple we applied to ten in July 2009, due primarily to the improvement in the public equity markets during this period.

 

In addition, this determination took into account our expectation that we would undertake an initial public offering within one year.

 

September 25, 2009 Fair Value Calculation. The fair value of our common stock as of September 25, 2009 was retrospectively determined to be $11.00 per share. The primary reason for the increase in the valuation of our common stock between July 22, 2009 and September 25, 2009 was the 17% increase in our next 12 months projected adjusted EBITDA between those two dates. Our next 12 months projected adjusted EBITDA in September 2009 had increased from our next 12 months projected adjusted EBITDA in July 2009, for the following reasons:

 

 

The valuation of our common stock in September 2009 was also affected by an increase, between July 2009 and September 2009, in the multiple of market valuations of comparable companies that we applied to our next 12 months projected adjusted EBITDA. The multiple we applied in this analysis in July 2009, derived from publicly available data on the comparable companies we used in the market approach, was 10. We increased the multiple we applied to 11 in September 2009, due primarily to the improvement in the public equity markets during this period.

 

Our determination of fair market value in September 2009 also took into account our expectation that we would undertake an initial public offering within nine months.

 

We have incorporated the fair values calculated in the retrospective valuations into the Black-Scholes option pricing model when calculating the stock-based compensation expense to be recognized for the stock options granted during the period from July through September 2009. The retrospective valuations generated per share fair values of common stock of $9.00 and $11.00, respectively, at July 22, 2009 and September 25, 2009. This resulted in intrinsic values of $2.945 and $4.945 per share, respectively, at each grant date.

 

April 26, 2010 Fair Value Calculation.  The fair value of our common stock as of April 26, 2010 and May 28, 2010 was determined contemporaneously to be $13.045 per share. In determining this value, we employed the same methods and approaches used in the retrospective analyses described above. The primary

reasons for the increase in the valuation of our common stock from September 25, 2009 to April 26, 2010 and May 28, 2010 were:

 

 

Valuation models require the input of highly subjective assumptions. There are significant judgments and estimates inherent in the determination of these valuations. These judgments and estimates include assumptions regarding our future performance, the time to undertaking and completing an initial public offering or other liquidity event, as well as determinations of the appropriate valuation methods. If we had made different assumptions, our stock-based compensation expense, net income and net income per share could have been significantly different. Additionally, because our capital stock prior to this offering had characteristics significantly different from that which will apply upon the closing of this offering, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing models do not necessarily provide a reliable, single measure of fair value. The foregoing valuation methodologies are not the only valuation methodologies available and will not be used to value our Class A or Class B common stock once this offering is complete. We cannot make assurances regarding any particular valuation of our shares.

 

Internal Control Over Financial Reporting

 

We had a material weakness in our internal control over financial reporting in each of 2007, 2008 and 2009. A material weakness is defined as a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis by the company’s internal controls. We do not currently have personnel with an appropriate level of knowledge, experience and training in the selection, application and implementation of GAAP as it relates to certain complex accounting issues, income taxes and SEC financial reporting requirements. This constitutes a material weakness, which we plan to remediate by hiring additional personnel with the requisite expertise. See “Risk Factors — We have a material weakness in our internal control over financial reporting. If we fail to establish and maintain proper and effective internal controls, our ability to produce accurate financial statements could be impaired, which could adversely affect our operating results, our ability to operate our business and investors’ and customers’ views of us.”

 

Results of Operations

 

Three Months Ended March 31, 2010 and 2009

 

Revenue

 

Total revenue. Total revenue increased by $32.2 million, or 43.9%, in the first quarter of 2010 compared to the first quarter of 2009 due to higher revenue from both energy efficiency and renewable energy.

 

Energy efficiency revenue. Energy efficiency revenue increased by $17.6 million, or 30.9%, in the first quarter of 2010 compared to the first quarter of 2009 due to an increase in the number of projects being installed for our municipal and other institutional customers.

 

Renewable energy revenue. Renewable energy revenue increased by $14.6 million, or 90.2%, in the first quarter of 2010 compared to the first quarter of 2009. The increase was primarily due to the greater number of renewable energy facilities being built by us for our customers. Construction volume of such plants increased by $12.5 million in the first quarter of 2010. Additionally, during the first quarter of 2010, we placed in service nine new facilities owned by us that sell to our customers electricity generated from LFG or

solar energy or provide for delivery of LFG. Partially offsetting this increase in revenue was a decline in sales of PV systems and components as declining market prices and shifting demand continue to impact the market for these products.

 

Revenue from customers outside the United States, principally Canada, was $18.7 million in the first quarter of 2010 compared to $13.9 million in the first quarter of 2009.

 

Business segment revenue. Total revenue for the U.S. federal segment increased $12.9 million, or 107.2%, to $24.9 million in the first quarter of 2010, compared to the first quarter of 2009, primarily due to increased installation of renewable energy facilities and other projects. Revenue recognized on the installation of a renewable energy project for the U.S. Department of Energy accounted for a significant portion of our revenue for this segment in the first quarter of 2010. Total revenue for the central U.S. region segment increased $7.5 million, or 67.5%, to $18.6 million in the first quarter of 2010, compared to the first quarter of 2009, primarily due to the increased installation of energy efficiency projects. Total revenue for the Canada segment increased $5.4 million, or 41.5%, in the first quarter of 2010, to $18.4 million, compared to the first quarter of 2009, primarily due to a larger volume of construction activity related to the installation of energy efficiency measures, particularly two large projects for housing authorities. Total revenue from the other U.S. regions segment increased $4.3 million, or 24.5%, to $21.7 million in the first quarter of 2010, compared to the first quarter of 2009, primarily due to an increase in the size and, to a lesser extent, the number of projects under construction. Total revenue not allocated to segments and presented as all other increased $2.2 million, or 11.1%, to $22.1 million in the first quarter of 2010, compared to the first quarter of 2009, primarily due to increased renewable energy sales, partially offset by slower sales of renewable energy products.

 

Direct Expenses and Gross Profit

 

Total direct expenses. Direct expenses increased by $27.5 million, or 46.1%, in the first quarter of 2010 compared to the first quarter of 2009. Lower gross profit margins in the first quarter of 2010 caused direct expenses to increase at a greater rate than revenue.

 

Energy efficiency. Energy efficiency gross margin decreased to 16.5% in the first quarter of 2010 from 18.3% in the same period in 2009. The decrease was primarily due to our recognition of additional profit in the first quarter of 2009 on certain of our construction projects that we were able to complete at total costs below their construction budget.

 

Renewable energy. Renewable energy gross margin declined to 19.6% in the first quarter of 2010 from 20.0% in the first quarter of 2009 due to additional costs required to bring certain facilities for federal customers into operation.

 

Operating Expenses

 

Salaries and benefits. Salaries and benefits increased by $2.1 million, or 34.5%, in the first quarter of 2010 as compared with the first quarter of 2009. This was primarily due to the increased headcount necessary to manage our expectation of an increase in our business activity in fiscal 2010 and beyond.

 

Project development. Project development expenses increased by $0.4 million, or 14.3%, in the first quarter of 2010 compared to the first quarter of 2009. The higher expenses reflected our efforts to increase proposal activity and to finalize the contracts related to awarded projects.

 

General, administrative and other. General, administrative and other expenses increased by $0.3 million, or 7.8%, in first quarter of 2010 compared to the first quarter of 2009, as we incurred higher costs for office-related expenses, corporate franchise fees, and expenses related to the hiring of temporary employees.

Other Income (Expense)

 

Other income (expense) decreased by $0.8 million to a net expense of $0.9 million in the first quarter of 2010 from a net expense of $24,000 in the first quarter of 2009. The decrease was due primarily to changes in the unrealized loss on derivatives. The following table presents the changes in other income (expense) from the first quarter of 2009 to the first quarter of 2010:

 

 

Income Before Taxes

 

Income before taxes for the first quarter of 2010 increased to $1.7 million from $0.6 million for the first quarter of 2009. The increase was primarily due to higher gross profit, which was partially offset by increases in operating expenses and other net expenses.

 

Business Segment Income Before Taxes.  Income before taxes for the U.S. federal segment increased $0.5 million, or 37.4%, in the first quarter of 2010 compared to the first quarter of 2009, primarily due to increased revenue, partially offset by our recognition of additional profit in the first quarter of 2009 on certain of our construction projects that we were able to complete at total costs below their respective construction budgets. Income before taxes for the central U.S. region segment increased $0.8 million to $1.0 million in the first quarter of 2010 compared to the first quarter of 2009, primarily due to a combination of higher revenue and improved margins arising from better utilization of resources. Income before taxes for the Canada segment increased $0.3 million to $0.4 million in the first quarter of 2010 compared to the first quarter of 2009, primarily due to higher revenue and improved margins earned on projects. Income before taxes for the other U.S. regions segment increased by $0.9 million, or 77.2%, to $2.2 million in the first quarter of 2010 compared to the first quarter of 2009. The increase in this segment was primarily due to increased revenue and an increase in the profit margin during the first quarter of 2010 from the same period in 2009, as the segment avoided certain cost overruns that impacted results in 2009. The loss before taxes not allocated to segments and presented as all other, increased by $1.6 million, or 68.8%, to $3.9 million in the first quarter of 2010, compared to the first quarter of 2009, primarily due to the lower margins on renewable energy sales, and an increase in both operating expenses and other expenses. The amounts of unallocated corporate expenses for the first quarters of 2009 and 2010 were $6.5 million, and $7.3 million, respectively. The changes in the expenses allocated to all other from the first quarter of 2009 to the first quarter of 2010 were consistent with the overall change in consolidated expenses discussed above. Income before taxes and unallocated corporate expenses for all other was $3.4 million in the first quarter of 2010, a $0.7 million, or 17.1%, decrease compared to the first quarter of 2009.

 

Provision for Income Taxes

 

The provision for income taxes increased by $0.2 million to $0.4 million in the first quarter of 2010 from $0.2 million for the first quarter of 2009. The effective tax rate decreased to 25.2% for the first quarter of 2010 from 35.0% in the first quarter of 2009. The rate variance between the periods is due mainly to a change in permanent items from 2009 to 2010. The principal difference between the statutory rate and the effective rate was due to deductions permitted under Section 179(d) of the Code, which relate to the installation of certain energy efficiency equipment in federal, state, provincial and local government-owned buildings, as well as production tax credits to which we are entitled from the electricity generated by certain plants that we own.

Net Income

 

Net income increased by $0.9 million, or 206%, in the first quarter of 2010 to $1.3 million, compared to $0.4 million in the first quarter of 2009, due to higher pre-tax income, which was partially offset by an increase in the tax provision. Earnings per share in the first quarter of 2010 were $0.10 per basic share and $0.03 per diluted share, representing an increase of $0.06 and $0.02, respectively, from the first quarter of 2009. The weighted-average number of basic and diluted shares outstanding increased by 38.1% and 11.0%, respectively, as a result of the vesting of restricted shares, exercise of stock options, and the grant of new stock options.

 

Years Ended December 31, 2009, 2008 and 2007

 

Revenue

 

Total revenue. Total revenue increased by $32.6 million, or 8.3%, from 2008 to 2009, due primarily to an increase in energy efficiency revenue and, to a lesser extent, an increase in renewable energy revenue. Total revenue increased by $17.4 million, or 4.6%, from 2007 to 2008 due to an increase in renewable energy revenue, offset in part by a decrease in energy efficiency revenue.

 

Energy efficiency revenue. Energy efficiency revenue increased by $15.6 million, or 4.8%, from 2008 to 2009, due to an increase in the number of new projects for municipal and other institutional customers that commenced in late 2008 and continued through 2009. Revenue decreased by $20.9 million, or 6.0%, from 2007 to 2008, primarily because the size of our energy efficiency projects in the Canadian market decreased significantly from an unusually high level in 2007.

 

Renewable energy revenue. Renewable energy revenue increased by $17.1 million, or 24.1%, from 2008 to 2009, due mainly to an increase in the number of LFG and biomass facilities being built by us for federal agencies. Construction volume of such plants increased by $15.7 million from 2008 to 2009. Additionally, in 2009, we placed in service eight new plants owned by us that sell and deliver LFG, or electricity generated by LFG, to customers. Partially offsetting this increase in revenue was a decline in the sales of PV systems and components, primarily due to a decline in market prices of solar panels. In 2008, renewable energy revenue increased by $38.3 million, or 117.6% from 2007. The increase in 2008 was due primarily to increased sales of solar energy products and services, reflecting the first full year of sales from Southwestern Photovoltaic, Inc., or SWPV, which we acquired in May 2007. Also contributing to the increase in 2008, to a lesser extent, was an increase in revenue from the construction of biomass and LFG plants for federal agencies.

 

Revenue from customers outside the United States, principally Canada, was $86.9 million in 2009, compared with $87.3 million in 2008 and $100.4 million in 2007.

 

Business segment revenue. Total revenue for the U.S. federal segment increased from 2008 to 2009 by $18.3 million, or 26.3%, to $87.6 million, primarily due to an increase in the number of projects being installed primarily for the U.S. federal government. During 2009, work commenced, and revenue was recognized, on the installation of a large renewable energy project for the U.S. Department of Energy. Total revenue for the U.S. federal segment increased from 2007 to 2008 by $7.1 million, or 11.4%, to $69.3 million, primarily as a result of increased construction of energy efficiency measures. Total revenue for the central U.S. region segment increased from 2008 to 2009 by $13.1 million, or 17.4%, to $88.1 million, primarily due to an increase in the number of energy efficiency projects in construction. Total revenue for the central U.S. region segment increased from 2007 to 2008 by $9.2 million, or 14.1%, to $75.0 million, also primarily due to an increase in the number of energy efficiency projects in construction. Total revenue in 2009 for the Canada segment was virtually flat, decreasing by $0.4 million, or 0.4%, compared to 2008, to $83.6 million. Total revenue for the Canada segment decreased from 2007 to 2008 by $16.2 million, or 16.2%, to $84.0 million, primarily due to a slowdown in the installation of energy efficiency measures. Total revenue for the other U.S. regions segment decreased from 2008 to 2009 by $0.8 million, or 1.1% to $77.8 million. Total revenue for the other U.S. regions segment decreased from 2007 to 2008 by $2.3 million, or 2.9%, to $78.7 million. The decreases in both years were primarily due to a generally flat level of business throughout

the period in the other U.S. regions segment. Total revenue not allocated to segments and presented as all other, increased from 2008 to 2009 by $2.6 million, or 2.9%, to $91.4 million, due to increases in O&M revenues and the sales of renewable energy products. Total revenue not allocated to segments and presented as all other increased from 2007 to 2008 by $19.5 million, or 28.2%, to $88.8 million, primarily due to an increase in sales of renewable energy products.

 

Direct Expenses and Gross Profit

 

Total direct expenses. Direct expenses increased by $30.2 million, or 9.5%, from 2008 to 2009, due to higher revenue. Lower profit margins caused direct expenses to increase at a greater rate than revenue. Direct expenses increased by $6.5 million, or 2.1%, from 2007 to 2008, due to the increase in revenue, but at a slower rate as profit margins improved during the year. Direct expenses generally increase or decrease as related revenue increases or decreases.

 

Energy efficiency. Energy efficiency gross margin decreased from 20.3% in 2008 to 17.2% in 2009, due primarily to cost overruns on several projects, as well as lower budgeted margins on certain Canadian projects. Energy efficiency gross margin increased from 17.4% in 2007 to 20.3% in 2008 due primarily to the recovery of a cost contingency for a project that was completed without requiring the use of such contingency and the recovery of a cost contingency relating to an O&M contract that was terminated as part of a settlement with a customer.

 

Renewable energy. Renewable energy gross margin increased from 15.9% in 2008 to 24.4% in 2009 as a result of the completion of seven new renewable energy plants, which typically have higher margins than PV products. Renewable energy gross margins decreased from 19.9% in 2007 to 15.9% in 2008 due primarily to a higher proportion of sales in 2008 represented by PV products.

 

Operating Expenses

 

Salaries and benefits. Salaries and benefits declined $2.0 million, or 6.7%, from 2008 to 2009, as a higher proportion of salaries and benefits was allocated to direct expense due to the increased utilization rates of our staff resulting from the higher volume of development and construction activity in 2009. Lower employee incentive payments also contributed to the decrease. Salaries and benefits increased from 2007 to 2008 by $4.4 million, or 17.0%, due primarily to the addition of personnel from the acquisition of SWPV and other staff additions.

 

Project development. Project development expenses declined $3.5 million, or 26.8%, from 2008 to 2009, and increased $5.0 million, or 62.6%, from 2007 to 2008. Our project development expenses were unusually high in 2008 as a result of a major marketing and rebranding initiative that we undertook and delays in projects due to the limited availability of financing for our customers. Expenses that we incurred during such delays are recorded as project development expenses rather than direct expenses.

 

General, administrative and other. General, administrative and other expenses increased $7.3 million, or 79.5%, from 2008 to 2009, and declined by $3.9 million, or 29.6%, from 2007 to 2008. In 2008, we recorded as a reduction to general, administrative and other expenses the sum of $5.8 million reflecting the recovery of a contingency that we had established in connection with our acquisition of Select Energy in 2006. Also in 2008, we incurred an additional $2.0 million of general, administrative and other expenses due to the first full year of operations of SWPV. In 2009, general, administrative and other expense included $2.2 million paid by us to settle a dispute with a competitor related to our PV business.

 

Other Income (Expense)

 

Other income (expense) increased from 2008 to 2009 by $6.7 million, from a net expense of $5.2 million to a net income of $1.6 million, due primarily to realized and unrealized gains from derivatives. In 2008, net expense increased by $2.0 million, or 65.3%, due to an increase in unrealized losses on derivatives and an increase in net interest expense. The following table shows the changes in other income (expense) from 2007 to 2008 and from 2008 to 2009:

 

 

Income Before Taxes

 

Income before taxes increased from 2008 to 2009 by $7.4 million, or 37.8%, due to realized and unrealized gains on derivatives. In 2008, we recorded a $5.8 million contingency recovery. Adjusting for the effect of the 2009 gains on derivatives and the 2008 contingency recovery, income before taxes in 2009 would have increased by $8.5 million, or 62.5%, compared to 2008. Higher revenue and improving margins were the principal reasons for the improvement in the adjusted results.

 

Income before taxes increased from 2007 to 2008 by $3.2 million, or 19.9%, due to the contingency recovery described above, partially offset by unrealized losses on derivatives and higher depreciation charges.

 

Business Segment Income Before Taxes.  Income before taxes for the U.S. federal segment increased from 2008 to 2009 by $6.3 million, or 124.8%, to $11.3 million. The increase was primarily due to increased revenue and higher margins recognized on project installations. In 2009, we recognized additional operating profit on certain of our construction projects that we were able to complete at a total cost below the respective construction budgets. In 2008, income before taxes for the U.S. federal segment increased from 2007 to 2008 by $0.8 million, or 18.6%, to $5.0 million. Higher revenue, along with better operating margins, were the primary contributors to this increase.

 

Income before taxes for the central U.S. region segment increased from 2008 to 2009 by $2.0 million, or 24.1%, to $10.1 million. The increase was primarily due to higher revenue and improved margins arising from more effective utilization of resources. Income before taxes for the central U.S. region segment decreased from 2007 to 2008 by $0.6 million, or 7.1%, to $8.2 million. The decrease was primarily due to lower realized margins on installed projects and a significant increase in the development of new projects resulting in increased costs that are incurred prior to the commencement of construction and the associated recognition of revenue.

 

Income before taxes for the Canada segment was unchanged at $4.2 million in both 2009 and 2008, which was consistent with the slight change in revenue for this segment. Income before taxes for the Canada segment decreased from 2007 to 2008 by $1.9 million, or 31.5%, to $4.2 million. This decrease was primarily due to the decrease in total revenue and a decrease in margins related to lower utilization rate for staff and other resources.

 

Income before taxes for the other U.S. regions segment decreased from 2008 to 2009 by $7.8 million, or 60.4%, to $5.1 million, primarily due to a decrease in gross profit margins. The lower gross profit margins were the result of a higher number of low margin projects accepted during a period of slower business activity in order to maintain utilization levels. Income before taxes for the other U.S. regions segment increased from 2007 to 2008 by $5.2 million, or 67.8%, primarily due to an improvement in gross profit margins, due largely to a reduction in construction cost overruns.

 

The loss before taxes not allocated to segments and presented as all other, decreased from 2008 to 2009 by $6.9 million, or 64.7%, to $3.8 million, primarily due to an increase in other income. The loss before taxes not allocated to segments and presented as all other increased from 2007 to 2008 by $0.2 million, or 2.0%, to $10.7 million, primarily due to increases in operating expenses and other expenses, partially offset by the recovery of a contingency that we had established in connection with our acquisition of Select Energy in 2006. The amounts of unallocated corporate expenses for 2007, 2008 and 2009 were $28.8 million, $31.9 million and $25.1 million, respectively. The changes in the expenses allocated to all other from 2008 to

2009 and 2007 to 2008 were consistent with the overall change in consolidated expenses discussed above. Income before taxes and unallocated corporate expenses for all other was $21.3 million in 2009, a $0.1 million, or 0.2%, increase compared to 2008. Income before taxes and unallocated corporate expenses for all other was $21.3 million in 2008, a $3.0 million, or 16.2%, increase compared to 2007.

 

Provision for Income Taxes

 

The provision for income taxes is based on various rates set by federal, state, provincial and local authorities and are affected by permanent and temporary differences between financial accounting and tax reporting requirements. Our statutory rate, which is a combined federal and state rate, has ranged between 38.1% and 39.7%. During 2009, we recognized income taxes of $6.9 million, or 25.8% of pretax income. The principal difference between the statutory rate and the effective rate was due to deductions permitted under Section 179(d) of the Code, which relate to the installation of certain energy efficiency equipment in federal, state, provincial and local government-owned buildings, as well as production tax credits to which we are entitled from the electricity generated by certain plants that we own. These energy efficiency tax benefits accounted for a $3.0 million reduction in the 2009 provision, or a reduction of 11.1 percentage points in the effective rate.

 

In 2008, the tax provision was $1.2 million, or 6.2% of pre-tax income, as we recognized benefits of the Section 179(d) deduction. These cumulative benefits, plus production tax credits for electricity generation, resulted in an $8.0 million reduction in the tax provision, and decreased our effective rate by 40.9 percentage points.

 

In 2007, the tax provision was $5.7 million, or 35.1% of pre-tax income. The difference between the statutory rate and our effective rate was due primarily to the energy efficiency preferences from the Section 179(d) deduction and production tax credits for electricity generation, resulting in an $1.2 million reduction in the tax provision, and a decrease in the effective rate by 7.5 percentage points.

 

Net Income

 

Net income increased in 2009 by $1.6 million, or 8.9%, due to higher pre-tax income, partially offset by an increase in the tax provision. Earnings per share in 2009 were $1.99 per basic share, and $0.61 per diluted share, representing an increase of $0.28, or 16.4%, and $0.07, or 13.2%, respectively. The weighted-average number of basic and diluted shares decreased by 6.4% and 3.8%, respectively, as a result of share repurchases.

 

Net income in 2008 was $18.3 million, compared with $10.5 million in 2007, an increase of $7.7 million, or 73.3%. The increase was a result of higher income before taxes, and a significantly lower tax provision. Earnings per share were $1.71 per basic share and $0.54 per diluted share in 2008, representing an increase of 80.0% and 91.4%, respectively, from 2007. The weighted-average number of basic and diluted shares outstanding decreased in 2008 by 4.0% and 9.5%, respectively, as a result of share, option and warrant repurchases.

 

Liquidity and Capital Resources

 

Sources of liquidity. Since inception, we have funded operations primarily through cash flow from operations and various forms of debt. We believe that available cash and cash equivalents and availability under our revolving senior secured credit facility, combined with our access to credit markets and the net proceeds from this offering, will be sufficient to fund our operations through 2011 and thereafter.

 

Capital expenditures. Our total capital expenditures were $22.8 million in 2007, $43.0 million in 2008, and $21.6 million in 2009, which is net of $12.9 million in Section 1603 rebates. Section 1603 of the American Recovery and Reinvestment Tax Act of 2009 authorized the U.S. Department of the Treasury to make payments to eligible persons who place in service specified energy property. This property would have been eligible for production tax credits under the Code, but we elected to forego such tax in exchange for the payment made under Section 1603. Additionally, we invested $10.8 million for an acquisition in 2007 and

$0.7 million for an acquisition in 2009. We currently plan to make capital expenditures of approximately $29.4 million in 2010, principally for new renewable energy plants.

 

Cash flows from operating activities. Operating activities used $17.9 million of net cash during the three months ended March 31, 2010. During that period, we had net income of $1.3 million, which is net of non-cash compensation, depreciation, amortization, deferred income taxes, unrealized losses and other non-cash items totaling $4.1 million. Net decreases in accounts receivable and other assets provided another $4.3 million in cash. However, reductions in accounts payable and billings in excess of costs and estimated earnings used $27.6 million of cash. Changes in other liabilities provided the balance of net cash during the period.

 

Operating activities used $19.7 million of net cash during the three months ended March 31, 2009. During that period, we had net income of $0.4 million, which is net of non-cash compensation, depreciation, amortization, deferred income taxes, unrealized losses and other non-cash items totaling $5.1 million. Net decreases in accounts receivable and other assets provided another $2.4 million in cash. However, net reductions in accounts payable, billings in excess of costs and estimated earnings, and other liabilities used $27.6 million of cash.

 

Operating activities provided $45.3 million of net cash during 2009. In 2009, we had net income of $19.9 million, which is net of non-cash compensation, depreciation and amortization totaling $10.1 million, partially offset by a $2.3 million unrealized gain on derivatives. Increases in accounts payable and other liabilities contributed $36.7 million, and investment in federal projects used $52.9 million, in 2009. We also drew a total of $33.0 million in cash from restricted cash accounts maintained in connection with our federal ESPC and our renewable energy projects. We reflect restricted cash as an operating asset on our consolidated balance sheet and withdrawals from existing restricted cash accounts as cash flow from operations on our consolidated statements of cash flows. The creation of new restricted cash accounts is reflected as a decrease to cash flows from financing activities on our consolidated statements of cash flows. Certain of the cash generated from our federal ESPC receivable financing is held in restricted cash accounts to be used to pay for the cost of construction under our federal ESPCs. We withdrew $31.5 million in cash from these accounts during 2009. In addition, under the terms of our term loan agreements used to finance certain of our renewable energy projects, we are required to maintain restricted cash accounts to provide for operation and maintenance expenses incurred. We withdrew $1.5 million in cash from these accounts during 2009. Other changes in net assets and liabilities provided the balance of net cash during the year.

 

Operating activities provided $1.3 million of net cash during 2008. We had net income of $18.3 million which included non-cash compensation, depreciation and amortization totaling $6.7 million, impairments and write-downs totaling $4.8 million and a $2.8 million unrealized loss on derivatives. Net income also included a non-cash gain related to an acquisition of $5.9 million. Payments pursuant to contracts decreased by $7.6 million due primarily to late customer remittances. Inventory and project development costs used $3.8 million and $3.6 million, respectively. We also drew a total of $25.5 million in cash from restricted cash accounts maintained in connection with our federal ESPC and our renewable energy projects. We reflect restricted cash as an operating asset on our consolidated balance sheet and withdrawals from existing restricted cash accounts as cash flow from operations on our consolidated statements of cash flows. The creation of new restricted cash accounts is reflected as a decrease to cash flows from financing activities on our consolidated statements of cash flows. Certain of the cash generated from our federal ESPC receivable financing is held in restricted cash accounts to be used to pay for the cost of construction under our federal ESPCs. We withdrew $23.5 million in cash from these accounts during 2008. In addition, under the terms of our term loan agreements used to finance certain of our renewable energy projects, we are required to maintain restricted cash accounts to provide for operation and maintenance expenses incurred. We withdrew $2.0 million in cash from these accounts during 2008. Other changes in net assets and liabilities provided the balance of net cash during the year.

 

Operating activities provided $30.3 million of net cash during 2007. We had net income of $10.5 million which included non-cash compensation, depreciation and amortization totaling $6.6 million, a $2.0 million asset write-down and a $1.4 million unrealized loss from a derivative. Net income also included a

non-cash gain related to a securitization of $2.3 million. Activity related to federal projects contributed $11.4 million of cash and changes in net assets and liabilities used $3.9 million of net cash during the year.

 

Cash flows from investing activities. Cash used for investing activities during the three months ended March 31, 2010 totaled $6.3 million and consisted of capital investments of $5.9 million related to the development of renewable energy plants. Other investments related to leasehold improvements and office equipment.

 

Cash used for investing activities during the three months ended March 31, 2009 totaled $9.9 million and consisted of capital investments of $9.5 million related to the development of renewable energy plants. Other investments were related to leasehold improvements and office equipment.

 

Cash flows from investing activities primarily relate to capital expenditures to support our growth.

 

Cash used in investing activities totaled $22.3 million during 2009 and consisted of capital expenditures of $21.6 million, primarily related to the development of renewable energy plants. This amount was net of $12.9 million of Section 1603 rebates. Also, $0.7 million of cash was used for an acquisition.

 

Cash used in investing activities totaled $43.0 million during 2008 and consisted solely of capital expenditures primarily for development of renewable energy plants.

 

Cash used in investing activities totaled $33.6 million during 2007 and consisted of capital expenditures of $22.8 million, primarily related to the development of renewable energy plants. Also, $10.8 million of cash was used for an acquisition.

 

Cash flows from financing activities. Net cash used in financing activities during the three months ended March 31, 2010 totaled $0.01 million. We increased certain restricted cash accounts by $4.3 million to meet terms of our loan agreements, and repaid $1.3 million of long-term project debt. Additionally, we paid $0.2 million in financing related fees. Partially offsetting those payments were net draws on our revolving credit facility totaling $5.0 million and proceeds from long-term debt financing arrangements of $0.8 million.

 

Cash flows provided by financing activities during the three months ended March 31, 2009 totaled $18.6 million. Proceeds from a long-term debt financing arrangement and net draws on our credit facility were $15.1 million and $5.9 million, respectively. Partially offsetting those proceeds were $1.2 million used to pay down long-term debt, $0.9 million to repurchase outstanding shares from an employee, $0.2 million to meet a restricted cash requirement, and $0.1 million for financing-related fees.

 

Cash flows provided by financing activities totaled $4.1 million during 2009 and included proceeds, net of financing costs, of $25.4 million from a construction and term loan facility provided by a bank. These proceeds were offset by repayments of $14.6 million on our revolving senior secured credit facility, repayments of $3.6 million on other long-term debt and payments of $3.1 million into restricted cash accounts which we are required to maintain under the terms of our term loan agreements used to finance certain of our renewable energy projects to provide for operation and maintenance expenses incurred in connection with such projects.

 

Cash flows provided by financing activities totaled $22.2 million during 2008 and included proceeds of $34.5 million from our revolving senior secured credit facility and proceeds from project finance debt of $9.3 million. These proceeds were partially offset by repayments of $2.5 million on long-term debt, $2.9 million of project debt, $0.9 million in financing fees, $12.9 million for the repurchase of stock and warrants and payments of $2.4 million into restricted cash accounts which we are required to maintain under the terms of our term loan agreements used to finance certain of our renewable energy projects to provide for operation and maintenance expenses incurred in connection with such projects.

 

Cash flows used in financing activities totaled $3.2 million during 2007, primarily related to the repayment of long-term debt of $4.4 million, repayment of senior debt of $2.5 million and the repurchase of employee stock and options of $2.5 million, partially offset by $6.2 million of proceeds from project financing.

 

Subordinated Note

 

In connection with the organization of Ameresco, on May 17, 2000, we issued a subordinated note to our principal stockholder in the amount of $3.0 million. The subordinated note bears interest at the rate of 10.00% per annum, payable monthly in arrears, and is subordinate to our revolving senior secured credit facility. The subordinated note is payable upon demand. We incurred $0.3 million of interest related to the subordinated note during each of 2007, 2008 and 2009. We will repay in full the outstanding principal balance of, and all accrued but unpaid interest on, the note out of the proceeds of this offering.

 

Revolving Senior Secured Credit Facility

 

On June 10, 2008, we entered into a credit and security agreement with Bank of America, consisting of a $50 million revolving facility. The agreement requires us to pay monthly interest at various rates in arrears, based on the amount outstanding. This facility has a maturity date of June 30, 2011. The facility is secured by a lien on all of our assets other than renewable energy projects that we own that were financed by others, and limits our ability to enter into other financing arrangements. Availability under the facility is based on two times our EBITDA for the preceding four quarters, and we are required to maintain a minimum EBITDA of $20 million on a rolling four-quarter basis and a minimum level of tangible net worth. The full line of credit, less outstanding amounts, was available to us as of March 31, 2010. As of March 31, 2010, there was $24.9 million in principal outstanding under the facility. There was $34.5 million and $19.9 million in principal outstanding under the facility as of December 31, 2008 and 2009, respectively.

 

Project Financing

 

Construction and Term Loans. We have entered into a number of construction and term loan agreements for the purpose of constructing and owning certain renewable energy plants. The physical assets and the operating agreements related to the renewable energy plants are owned by wholly-owned, single member special purpose subsidiaries. These construction and term loans are structured as project financings made directly to a subsidiary, and upon acceptance of a project, the related construction loan converts into a term loan. While we are required under GAAP to reflect these loans as liabilities on our consolidated balance sheet, they are nonrecourse and not direct obligations of Ameresco, Inc. As of March 31, 2010, we had outstanding $58.0 million in aggregate principal amount under these loans, bearing interest at rates ranging from 6.9% to 8.7% and maturing at various dates from 2014 to 2025. As of December 31, 2009, we had outstanding $58.4 million in aggregate principal amount under these loans, bearing interest at rates ranging from 6.9% to 8.7% and maturing at various dates from 2014 to 2021. As of March 31, 2010 and December 31, 2009, a term loan in the amount of $5.0 million and $5.4 million, respectively, was in default as a result of the bankruptcy of the customer for the energy output of the plant financed by the loan. The bankruptcy filing by the customer constitutes an event of default under the credit agreement, which could subject us to an assessment of default interest charges. To date, no such interest charges have been assessed. This customer has emerged from bankruptcy, confirmed its obligations to our subsidiary and made all back payments together with interest. We are currently seeking to refinance this loan to cure the default.

 

Federal ESPC Receivable Financing. We have arrangements with certain lenders to provide advances to us during the construction or installation of projects for certain customers, typically federal governmental entities, in exchange for our assignment to the lenders of our rights to the long-term receivables arising from the ESPCs related to such projects. These financings totaled $57.3 million and $32.6 million in principal amount at March 31, 2010 and December 31, 2009, respectively. Under the terms of these financing arrangements, we are required to complete the construction or installation of the project in accordance with the contract with our customer, and the debt remains on our consolidated balance sheet until the completed project is accepted by the customer.
