In our opinion, such information includes all adjustments, consisting of only normal recurring adjustments, which are necessary to make our financial position at June 30, 2004 and the results of our operations for the six month periods ended June 30, 2004 and 2003 not misleading. As permitted by the rules and regulations of the Securities and Exchange Commission (SEC) the accompanying financial statements do not include all disclosures normally required by accounting principles generally accepted in United States of America. These financial statements should be read in conjunction with the financial statements included in our Annual Report on Form 10-KSB for the year ended December 31, 2003 on file with the SEC. In our opinion, the consolidated financial statements are a fair presentation of the financial position, results of operations and cash flows for the periods presented. The results of operations for the six months ended June 30, 2004 are not necessarily indicative of the results of operations to be expected for the full fiscal year ending December 31, 2004. (2) Stock-based Compensation Statement of Financial Accounting Standards No. 123, ("SFAS 123") "Accounting for Stock-Based Compensation," encourages, but does not require, the adoption of a fair value-based method of accounting for employee stock-based compensation transactions. We have elected to apply the provisions of Accounting Principles Board Opinion No. 25 ("Opinion 25"), "Accounting for Stock Issued to Employees," and related interpretations, in accounting for our employee stock-based compensation plans. Under Opinion 25, compensation cost is measured as the excess, if any, of the quoted market price of our stock at the date of the grant above the amount an employee must pay to acquire the stock. Had compensation costs for options granted to our employees been determined based on the fair value at the grant dates consistent with the method proscribed by SFAS No. 123, our net income and earnings per share would have been reduced to the pro forma amounts listed below: Three Months Ended Six Months Ended June 30 June 30 2004 2003 2004 2003 ----------- ----------- ----------- ----------- Pro forma impact of fair value method Income applicable to common shares, as reported $ 340,401 $ 284,142 $ 2,206,218 $ 371,015 Pro-forma stock-based compensation costs under the fair value method, net of related tax (10,000) (7,683) (20,000) (15,365) ----------- ----------- ----------- ----------- Pro-forma income applicable to common shares under the fair-value method $ 330,401 $ 276,459 $ 2,186,218 $ 355,650 Earnings per common share Basic earnings per share reported $0.06 $0.06 $0.42 $0.08 Diluted earnings per share reported $0.06 $0.06 $0.39 $0.07 Pro-forma basic earnings per share under the fair value method $0.06 $0.06 $0.42 $0.07 Pro-forma diluted earnings per share under the fair value method $0.06 $0.05 $0.39 $0.07 4 Weighted average Black-Scholes fair value assumptions: Risk free rate 4.0%-5.2% Expected life 5-10 yrs Expected volatility 50.0% Expected dividend yield 0.0% (3) Merger On January 1, 2004, we merged our subsidiaries, Rotary Gas Systems Inc, NGE Leasing Inc, and Great Lakes Compression Inc. with the parent Company, Natural Gas Services Group Inc. This had no effect on our consolidated financial position or results of operations, with the exception of a small impact on our state tax expenses. (4) Preferred Stock Conversion In accordance with the provisions of the Convertible Series A Preferred Stock of Natural Gas Services Group, Inc., on March 26, 2004 each share of Preferred Stock automatically converted to one share of Common Stock. The conversion occurred after the closing market price of the stock was equal to or higher than $6.50 for 20 consecutive trading days. 315,154 Preferred shares were converted at that time. Dividends payable at the conversion date were approximately $25,355. (5) Common Stock Private Placement On July 20, 2004, Natural Gas Services Group, Inc. and CBarney Investments, Ltd. entered into a Securities Purchase Agreement. Under this agreement, Natural Gas Services Group issued and sold 649,574 shares of its common stock to CBarney at $7.69736 per share. The per share price was determined by multiplying (x) $8.747, the average closing market price of the common stock on the American Stock Exchange for the twenty consecutive trading days ended July 15, 2004, times (y) eighty-eight percent. Natural Gas Services Group received aggregate gross proceeds of $5,000,000. We plan to use the net proceeds from the sale of the stock to advance the growth of our rental fleet of natural gas compressors, working capital and general corporate purposes, including possible acquisition of strategically located compressor companies. (6) Earnings per common share The following table reconciles the numerators and denominators of the basic and diluted earnings per share computation. Three Months Ended Six Months Ended June 30, June 30, 2004 2003 2004 2003 ----------- ----------- ----------- ----------- Basic earnings per share Numerator: Net income $ 365,756 $ 315,152 $ 2,259,4925 $ 433,035 Less: dividends on preferred shares (25,355) (31,010) (53,277) (62,020) Net income available to common shareholders $ 340,401 $ 284,142 $ 2,206,218 $ 371,015 5 Denominator - Weighted average common shares outstanding 5,396,527 4,875,324 5,230,927 4,866,527 Basic earnings per share $ 0.06 $ 0.06 $ 0.42 $ 0.08 Diluted earnings per share Numerator: Net income $ 365,756 $ 315,152 $ 2,259,495 $ 433,035 Less: dividends on preferred shares (1) (25,355) (31,010) (53,277) (62,020) Net income available to common shareholders $ 340,401 $ 284,142 $ 2,206,218 $ 371,015 Denominator : Weighted average common shares outstanding 5,396,527 4,875,324 5,230,927 4,866,527 Dilutive effect of common stock options and warrants 214,588 149,450 367,820 249,805 5,611,115 5,024,774 5,598,747 5,116,332 Diluted earnings per share $ 0.06 $ 0.06 $ 0.39 $ 0.07 -------------------------------------------------------------------------------- (1) Preferred shares were anti-dilutive for the three and six months ended June 30, 2004 and 2003 (7) Other Income On March 15, 2004 the President and C.E.O. of our company, Mr. Wayne L. Vinson, passed away after a battle with cancer. The Company held 2 life insurance policies on him, 1 for $1,000,000 and 1 for $500,000, with the Company as the beneficiary. The proceeds of $1,500,000 were recorded as other income. 6 Item 2. Management's Discussion and Analysis, or Plan of Operation Overview Our company provides products and services to the oil and gas industry and is engaged in (1) the manufacture, service, sale, and rental of natural gas compressors to enhance the productivity of oil and gas wells, and (2) the manufacture, sale and rental of flares and flare ignition systems for plant and production facilities. Critical Accounting Policies and New Accounting Pronouncements See our December 31, 2003 Form 10-KSB on file with the SEC for a discussion of our critical accounting policies and new accounting pronouncements. There have been no substantive changes since that time. Liquidity and Capital Resources We have funded our operations through public and private offerings of our common and preferred stock, subordinated debt and bank debt. Proceeds were primarily used to pay debt and to fund the manufacture and fabrication of additional units for our rental fleet of natural gas compressors. At June 30, 2004, we had cash and cash equivalents of approximately $227,300, working capital of $56,200 and non-subordinated debt of $11,415,000 of which approximately $2,742,000 was classified as current. We had positive net cash flow from operating activities of approximately $3,136,600 during the first six months of 2004. This was primarily from net income of $2,259,000 plus depreciation and amortization of $1,109,000 an increase in deferred taxes of $481,000, an increase in accounts payable and accrued liabilities of $952,000, offset by an increase in accounts receivable-trade of $494,000, a decrease in deferred income of $194,000, and an increase in inventory of $950,000. On November 24, 2003 we completed a new $10 million senior credit facility with a $7 million initial borrowing base. The credit facility is a Multiple Advance Term Promissory Note arranged by Western National Bank, Midland, Texas. The interest rate is one percent over Wall Street prime rate. Funds have been drawn under this line as of June 30, 2004 totaling $3,615,000. Our line of credit for $750,000 with interest at 1% over prime for one year expired March 15, 2004 but was renewed on May 28, 2004. Funds have been drawn under the line of credit as of June 30, 2004 totaling $361,000. In accordance with the provisions of the Convertible Series A Preferred Stock of Natural Gas Services Group, Inc., on March 26, 2004 each share of Preferred Stock automatically converted to one share of Common Stock. The conversion occurred after the closing market price of the stock was equal to or higher than $6.50 for 20 consecutive trading days. 315,154 Preferred shares were converted at that time. As a result the conversion we will have a reduction in expected dividend payments of approximately $68,000 for the remainder of the year 2004. On July 20, 2004, Natural Gas Services Group, Inc. and CBarney Investments, Ltd. entered into a Securities Purchase Agreement. Under this agreement, Natural Gas Services Group agreed to issue and sell 649,574 shares of its common stock to CBarney at $7.69736 per share. The per share price was determined by multiplying (x) $8.747, the average closing market price of the common stock on the American Stock Exchange for the twenty consecutive trading days ended July 15, 2004, times (y) eighty-eight percent. Natural Gas Services Group will receive aggregate gross proceeds of $5,000,000. We plan to use the net proceeds from the sale of the stock to advance the growth of our rental fleet of natural gas compressors, working capital and general corporate purposes, including possible acquisition of strategically located compressor companies. 7 Results of Operations Six Months Ended June 30, 2004, Compared to the Six Months Ended June 30, 2003. Sales revenue from outside sources increased from $1,505,000 to $1,742,000, or 16% for the six months ended June 30, 2004 compared to the same period ended June 30, 2003. This increase was mainly the result of an improvement in the sale of compressors and flare units compared to the same period in 2003. Because our products are custom-built, fluctuations in revenue from outside sources is not unusual. Service and maintenance revenue increased from $894,000 to $934,000, or 4% for the six months ended June 30, 2004 compared to the same period ended June 30, 2003. Leasing revenue increased from $3,166,000 to $4,674,000, or 48% for the six months ended June 30, 2004 compared to the same period ended June 30, 2003. This increase was the result of additional units added to our rental fleet and leased to third parties. The company ended the period with 488 compressor packages in its rental fleet, up from 399 units at December 31, 2003 and 354 units at June 30, 2003. 8 The gross margin percentage increased from 54% for the six months ended June 30, 2003, to 56% for the same period ended June 30, 2004. This improvement resulted mainly from the relative increase in leasing revenue as a percentage of the total revenue. Our rental fleet carries a gross margin averaging 70%, and increases in rented units improves our gross margin. Selling, general and administrative expense increased from $1,116,000 to $1,346,000 or 21% for the six months ended June 30, 2004, as compared to the same period ended June 30, 2003. This was mainly the result of the increase in commissions from additional leasing contracts on gas compressors to third parties and legal expenses related to an internal investigation concerning an employee matter that was settled in April 2004. Depreciation and amortization expense increased 42% from $780,000 to $1,109,000 for the six months ended June 30, 2004, compared to the same period ended June 30, 2003. This increase was the result of 134 new gas compressor rental units being added to rental equipment from June 30, 2003 to June 30, 2004. Other income and expense increased approximately $1,493,000 for the six months ended June 30, 2004 compared to the same period ended June 30, 2003. This increase was due mainly from the receipt of $1,500,000 in life insurance payable on Mr. Wayne L. Vinson, our former President and C.E.O. His death on March 15, 2004 left the company as the beneficiary of two life insurance policies, one for $1,000,000, and one for $500,000. Interest expense increased 14% for the six months ended June 30, 2004 compared to the same period ended June 30, 2003, mainly due to the increased loan balances on vehicles and rental equipment. Provision for income tax increased $164,000 or 51%, primarily due to the increase in net taxable income. The income from the life insurance proceeds described above is not subject to federal income tax. 9 Three Months Ended June 30, 2004, Compared to the Three Months Ended June 30, 2003. Sales revenue from outside sources decreased from $940,000 to $852,000, or 9% for the three months ended June 30, 2004 compared to the same period ended June 30, 2003. This decrease was mainly the result of a reduction in the sales of compressor units and parts. Because our products are custom-built, fluctuations in compressor unit revenue from outside sources is not unusual. The reduction in parts sales is the result of a change in our discount status with a major supplier in Northern Michigan. We expect this to be a temporary situation. Service and maintenance revenue decreased from $517,000 to $510,000, or 1% for the three months ended June 30, 2004 compared to the same period ended June 30, 2003. This revenue source is subject to seasonable change and we expect this to increase in the third quarter of 2004. Leasing revenue increased from $1,764,000 to $2,420,000, or 37% for the three months ended June 30, 2004 compared to the same period ended June 30, 2003. This increase was the result of additional units added to our rental unit fleet and leased to third parties. The company added 44 gas compressors to its rental fleet in the quarter ended June 30, 2004. The gross margin percentage remained stable at 55% for the three months ended June 30, 2003 and also for the same period ended June 30, 2004. Although we expect our margins to increase as our rental revenue increases because our rental fleet carries a gross margin averaging 70%, changes in the product mix during the quarter help to average out the gross margin company wide. 10 Selling, general and administrative expense increased from $596,000 to $680,000 or 14% for the three months ended June 30, 2004, as compared to the same period ended June 30, 2003. This was mainly the result of the increase in commissions from additional leasing contracts on gas compressors to third parties and an increase in sales and administration salary expense. Depreciation and amortization expense increased 39% from $418,000 to $582,000 for the three months ended June 30, 2004, compared to the same period ended June 30, 2003. This increase was the result of 44 new gas compressor rental units being added to rental equipment during the three months ended June 30, 2004. There was a slight increase in interest expense for the three months ended June 30, 2004 compared to the same period ended June 30, 2003, was mainly due to the increase in loan balances for rental equipment. Provision for income tax decreased $4,000, or 2%, primarily due from a change in our effective tax rate. The effective tax rate changed because of a reduction in our state taxes as a result the merger of our subsidiaries effective January 1, 2004. Item 3. Controls and Procedures (a) Evaluation of disclosure controls and procedures. Under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-14(c) under the Securities Exchange Act of 1934) as of the end of the period covered by this report. Based upon that evaluation, our chief executive officer and chief financial officer concluded that, as of the end of the period covered by this report, our disclosure controls and procedures are effective in timely alerting them to the material information relating to us that are required to be included in our periodic filings with the SEC. 11 (b) Changes in internal controls. There were no changes made in our internal controls during the period covered by this report that have materially affected or are reasonably likely to materially affect our internal controls over financial reporting. In addition, to our knowledge there were no changes, in other factors that could significantly affect these controls subsequent to the date of their evaluation.
