Horizon Therapeutics plc (Nasdaq: HZNP) today announced record third-quarter 2021 financial results and increased both its full-year 2021 net sales and adjusted EBITDA guidance.

“We generated record results in the third quarter and made significant progress executing our R&D strategy, further expanding our pipeline with five new programs,” said Tim Walbert, chairman, president and chief executive officer, Horizon. “In addition to our strong commercial execution with TEPEZZA and KRYSTEXXA, our expanded pipeline positions us to drive future growth and diversification, as well as address the unmet medical needs of many people living with rare, autoimmune and severe inflammatory diseases around the world.”

Third Quarter and Recent Company Highlights

• Announced Five New R&D Programs and Highlighted Expanded Pipeline at Inaugural R&D Day: In September, the Company announced four new programs for its development-stage candidate daxdilimab (HZN-7734) in alopecia areata, discoid lupus erythematosus, dermatomyositis and lupus nephritis and one new program for its development-stage candidate dazodalibep (HZN-4920) in focal segmental glomerulosclerosis. The Company expects to initiate Phase 2 trials in each of these indications in 2022. The new programs, in addition to the Company’s R&D strategy and other key programs, were highlighted at the Company’s inaugural R&D Day in September.
  
  
  
  
• Announced Positive Topline Data from KRYSTEXXA MIRROR Trial: In October, the Company announced positive topline results from the MIRROR Phase 4 randomized, placebo-controlled trial evaluating the use of KRYSTEXXA plus methotrexate. The MIRROR trial results demonstrated that 71 percent of patients who were randomized to receive KRYSTEXXA plus methotrexate achieved a complete response rate at Month 6 (p<0.001), a significant improvement from the 40 percent response rate in patients who were randomized to receive KRYSTEXXA plus placebo. In the Phase 3 clinical program, which evaluated KRYSTEXXA alone compared to placebo, 42 percent of patients receiving KRYSTEXXA achieved a complete response. The Company plans to submit a sBLA to the U.S. FDA in the first quarter of 2022. Full data from the trial is expected to be presented at future medical meetings. KRYSTEXXA plus immunomodulation is a core element of the Company’s strategy to maximize the value of KRYSTEXXA and enable more patients with uncontrolled gout to benefit from the medicine.
  
  
  
  
• Initiated Enrollment in TEPEZZA Chronic TED Trial: In September, the first patient was enrolled in a Phase 4 randomized, placebo-controlled clinical trial to evaluate the safety and efficacy of TEPEZZA for the treatment of chronic TED. TED is a serious, progressive and potentially vision-threatening rare autoimmune disease. It begins with an acute phase where inflammatory signs and symptoms, such as eye pain, swelling, proptosis (eye bulging) and diplopia (double vision), progress over time. The acute stage is followed by a chronic phase in which inflammation is no longer present or has markedly diminished; however, significant signs and symptoms may remain and continue to impact the quality of life. The objective of the trial is to generate clinical data to better inform physicians and payers about the safety and efficacy of TEPEZZA in patients with chronic TED. Results are expected in the second half of 2022.
  
  
  
  
• Presented New UPLIZNA^® (inebilizumab-cdon) Data at Key Medical Meetings: New UPLIZNA data were presented at the 15th World Congress on Controversies in Neurology (CONy Virtual), including end-of-study data from the open-label extension period of the Phase 3 trial in patients with neuromyelitis optica spectrum disorder (NMOSD). The data indicated that UPLIZNA may provide durable efficacy and a favorable safety profile for African Americans with NMOSD. Multiple new data were also presented at the virtual 37^th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) in October. Additionally, a new analysis of data from the Phase 3 trial was published in the Multiple Sclerosis Journal that highlighted a sustained effect on attack risk in people with NMOSD who were treated with UPLIZNA for four or more years.
  
  
  
  
• Acquired Biologics Manufacturing Facility in Waterford, Ireland: In July, the Company completed the acquisition of a biologics drug product manufacturing facility in Waterford, Ireland. The Company intends to use the manufacturing facility to support the growth of the Company’s on-market medicines, including TEPEZZA, KRYSTEXXA and UPLIZNA, as well as development-stage biologics.
  
  
  
  
• Continued to Demonstrate Gender and Ethnicity Pay Equity: A second study conducted by Aon, a leading compensation consulting firm, showed that Horizon continues to demonstrate both gender and ethnicity pay equity. This study was a follow-on study to the gender and pay ethnicity study Aon conducted in 2019. The Company maintained its gender and ethnicity pay equity despite having grown significantly in the two years since the first study, as well as having completed the acquisition of Viela Bio, which included the addition of a significant number of employees.
  
  
  
  
• Multiple Additional Recognitions as a Best Workplace: In September, the Company was named one of the “2021 Best Workplaces for Women™” by Fortune and Great Place to Work^® for the first time. In addition, the Company was also recognized as one of PEOPLE's “100 Companies That Care^®” for the third year. In July, Fortune and Great Place to Work named the Company to the “Best Workplaces for Millennials™” list for the second consecutive year and the Company was the highest ranked biotechnology company on the list. In addition, in October the Company was named one of the Top 100 Adoption-Friendly Workplaces by the Dave Thomas Foundation for Adoption for the third consecutive year. Most recently, Horizon was named to Newsweek’s inaugural “Most Loved Workplaces” list, ranking among the top 100 companies recognized for employee happiness and satisfaction at work and was the highest-ranked company in the biotechnology and pharmaceutical category. To date in 2021, the Company has received 11 workplace-related recognitions, reflecting the high level of engagement of its employees.

While segment operating income contains certain adjustments to the directly comparable GAAP figures in the Company’s consolidated financial results, it is considered to be prepared in accordance with GAAP for purposes of presenting the Company’s segment operating results.

• Third-quarter 2021 net sales of the orphan segment, the Company’s strategic growth segment, were $951.0 million, an increase of 78 percent over the prior year’s quarter, driven by the strong performance of TEPEZZA, KRYSTEXXA, RAVICTI, PROCYSBI and ACTIMMUNE. The orphan segment represented 92 percent of total company third-quarter net sales.
  
  
  
  
• KRYSTEXXA third-quarter 2021 net sales increased 46 percent year-over-year driven by increased adoption of KRYSTEXXA plus immunomodulation, which now exceeds 45 percent. In addition, the Company continues to see strong uptake of KRYSTEXXA from both rheumatologists and nephrologists.
  
  
  
  
• Third-quarter 2021 orphan segment operating income was $476.2 million, which includes additional investment associated with TEPEZZA, UPLIZNA and the Company’s pipeline programs.

• Third-quarter 2021 net sales of the inflammation segment were $86.0 million, and segment operating income was $34.1 million.

Note Regarding Use of Non-GAAP Financial Measures

EBITDA, or earnings before interest, taxes, depreciation and amortization, and adjusted EBITDA are used and provided by Horizon as non-GAAP financial measures. Horizon provides certain other financial measures such as non-GAAP net income, non-GAAP diluted earnings per share, non-GAAP gross profit and gross profit ratio, non-GAAP operating expenses, non-GAAP operating income, non-GAAP tax (benefit) and tax rate and non-GAAP operating cash flow, each of which include adjustments to GAAP figures. These non-GAAP measures are intended to provide additional information on Horizon’s performance, operations, expenses, profitability and cash flows. Adjustments to Horizon’s GAAP figures as well as EBITDA exclude acquisition and/or divestiture-related expenses, gain or loss from divestiture, gain or loss from sale of assets, upfront, progress and milestone payments related to license and collaboration agreements, litigation settlements, loss on debt extinguishment, costs of debt refinancing, drug manufacturing harmonization costs, restructuring and realignment costs, the income tax effect on pre-tax non-GAAP adjustments and other non-GAAP income tax adjustments, as well as non-cash items such as share-based compensation, depreciation and amortization, non-cash interest expense, long-lived asset impairment charges and other non-cash adjustments. Certain other special items or substantive events may also be included in the non-GAAP adjustments periodically when their magnitude is significant within the periods incurred. Horizon maintains an established non-GAAP cost policy that guides the determination of what costs will be excluded in non-GAAP measures. Horizon believes that these non-GAAP financial measures, when considered together with the GAAP figures, can enhance an overall understanding of Horizon’s financial and operating performance. The non-GAAP financial measures are included with the intent of providing investors with a more complete understanding of the Company’s historical and expected 2021 financial results and trends and to facilitate comparisons between periods and with respect to projected information. In addition, these non-GAAP financial measures are among the indicators Horizon’s management uses for planning and forecasting purposes and measuring the Company's performance. For example, adjusted EBITDA is used by Horizon as one measure of management performance under certain incentive compensation arrangements. These non-GAAP financial measures should be considered in addition to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. The non-GAAP financial measures used by the Company may be calculated differently from, and therefore may not be comparable to, non-GAAP financial measures used by other companies. Horizon has not provided a reconciliation of its full-year 2021 adjusted EBITDA outlook to an expected net income (loss) outlook because certain items such as acquisition/divestiture-related expenses and share-based compensation that are a component of net income (loss) cannot be reasonably projected due to the significant impact of changes in Horizon’s stock price, the variability associated with the size or timing of acquisitions/divestitures and other factors. These components of net income (loss) could significantly impact Horizon’s actual net income (loss).
