Horizon Therapeutics plc (Nasdaq: HZNP) today announced second-quarter 2022 financial results and revised its full-year 2022 net sales and adjusted EBITDA guidance.

“Double-digit net sales growth in our orphan segment drove our second-quarter performance, with very strong growth of KRYSTEXXA and an increasing contribution from UPLIZNA,” said Tim Walbert, chairman, president and chief executive officer, Horizon. “We were also pleased to receive FDA approval of our expanded KRYSTEXXA label in July, to include co-administration of KRYSTEXXA with methotrexate, which will enable many more patients to benefit from this important medicine.”

“We are revising our full-year guidance to reflect our expectation for TEPEZZA full-year net sales percentage growth in the high-teens and reflect recent generic competition in our inflammation segment. Importantly, our long-term outlook for TEPEZZA has not changed and we continue to estimate that our three key growth drivers TEPEZZA, KRYSTEXXA and UPLIZNA can generate aggregate global peak annual net sales of greater than $5.5 billion. We understand the dynamics impacting the pace of growth of TEPEZZA, and we are executing on our strategy to address them, including a more significant expansion of our TEPEZZA field force and implementing initiatives to drive further penetration. We are excited about the future prospects for Horizon, with our growth drivers, our expanding pipeline and our global expansion initiatives.”

Second Quarter and Recent Company Highlights

• Revised Full-Year 2022 TEPEZZA Net Sales Expectations; Confirming Global Peak Annual Net Sales Expectations: Today, the Company announced that it expects TEPEZZA full-year 2022 net sales percentage growth in the high-teens compared to its previous guidance of mid-30s percentage growth. In its prior guidance, the Company expected TEPEZZA trends to continue to show positive progress in the post-Omicron recovery. Following further analysis, the Company determined it needed to increase its efforts to activate and support core thyroid eye disease (TED) treating physicians and to drive an urgency among ophthalmologists and endocrinologists to diagnose and refer TED patients. The Company is executing on several opportunities to accelerate growth, including evolving its commercial focus and increasing the size of its TEPEZZA field force to a greater extent than originally planned. The Company continues to invest significantly in direct-to-consumer advertising. A recent internal market analysis also confirmed the size of the market at more than 100,000 addressable TED patients in the U.S., supporting the Company’s expectation to generate global peak annual net sales of more than $3.5 billion.
  
  
  
  
• FDA Approved Expanded Label for KRYSTEXXA to Include Co-Administration with Methotrexate: In July, the U.S. Food and Drug Administration (FDA) approved the supplemental Biologics License Application (sBLA) expanding the KRYSTEXXA label to include co-administration with methotrexate. The approval was based on 6-month and 12-month results from the MIRROR randomized controlled trial (RCT), which demonstrated significant improvement in response rate and sustained patient response of KRYSTEXXA with methotrexate compared to KRYSTEXXA with placebo (monotherapy). It also demonstrated significant reductions in infusion reactions in the KRYSTEXXA with methotrexate arm compared to monotherapy and no new safety signals were observed.
  
  
  
  
• Advancing the Company’s Global Expansion for UPLIZNA in Europe and Brazil: In April, the European Commission approved UPLIZNA for the treatment of adult patients with neuromyelitis optica spectrum disorder (NMOSD) who are Anti-Aquaporin-4 Immunoglobulin G Seropositive (AQP4-IgG+). The commercial launch of UPLIZNA in Germany is underway. In June, the Company submitted a regulatory filing to the Brazil National Health Surveillance Agency (ANVISA) for inebilizumab.
  
  
  
  
• Presented New KRYSTEXXA Data at EULAR 2022: In June, new data from the MIRROR RCT were presented at The EULAR 2022 European Congress of Rheumatology conference, showing KRYSTEXXA with methotrexate resulted in significant efficacy and safety improvements compared to KRYSTEXXA with placebo during Month 6. The MIRROR RCT demonstrated that 71% of patients receiving KRYSTEXXA with methotrexate achieved a complete response, a more than 30 percentage-point improvement compared to patients who were randomized to receive KRYSTEXXA with placebo (p<0.0001). Additionally, infusion reactions were seen in 4% of patients receiving KRYSTEXXA with methotrexate compared to 31% in patients randomized to receive KRYSTEXXA with placebo.
  
  
  
  
• Presented New TEPEZZA Data at ENDO 2022: In June, an analysis of pooled data from TEPEZZA clinical trials was presented at the annual conference of the Endocrine Society, ENDO 2022, reinforcing the safety profile in people with TED. Hyperglycemic events were reported in 10% of patients who received TEPEZZA, compared to 1.2% of patients who received placebo. All hyperglycemic events reported in TEPEZZA patients were controlled with medicine, did not cause treatment disruption and were most often seen in patients with pre-existing diabetes.
  
  
  
  
• Announced Positive Topline Proof-of-Concept Results from Dazodalibep Rheumatoid Arthritis Clinical Trial: In May, the Company announced positive topline results from the Phase 2 randomized placebo-controlled trial of dazodalibep in patients with rheumatoid arthritis (RA). The primary endpoint of the trial was met across all doses, a statistically significant change from baseline in DAS28-CRP, a standardized measure of disease activity in RA trials, at Day 113. In addition, dazodalibep was well tolerated across all doses. The impact observed after various doses will inform the dosing regimen for other studies with dazodalibep. Data from the trial will be presented at an upcoming medical meeting.
  
  
  
  
• Presented New UPLIZNA Data at Key Medical Meetings: In June, data from the Phase 3 trial were presented at the Consortium of Multiple Sclerosis Centers (CMSC) Annual Meeting that showed no significant differences in disease attacks or disability outcomes in patients with a specific genetic variation, often linked to poor treatment response, compared to those without. Additionally in June, a new analysis of data from the Phase 3 trial was presented at the 8^th Congress of the European Academy of Neurology (EAN) meeting, showing that European Union (EU) study participants receiving UPLIZNA had similar outcomes to non-EU patients. In April, multiple new data from the Phase 3 trial were presented at the American Academy of Neurology (AAN) 2022 Annual Meeting, including data showing no significant differences in attacks between NMOSD patients treated with UPLIZNA who previously experienced one pre-study attack and those who had experienced two or more pre-study attacks. At the same meeting, a separate analysis showed long-term treatment with UPLIZNA improved pain and quality of life outcomes for at least three years.
  
  
  
  
• Initiated Enrollment in Alopecia Areata Clinical Trial: In May, the first patient was enrolled in a Phase 2 clinical trial to evaluate daxdilimab in patients with alopecia areata, an autoimmune disorder characterized by nonscarring hair loss.
  
  
  
  
• Received Multiple Best Workplace Awards and Other ESG Recognitions: The Company has recently been recognized by Fortune in several best workplace awards – in April, the Company was named one of Fortune’s “100 Best Companies to Work For^®” for the second consecutive year, retaining the highest ranked position in the biotechnology/pharmaceutical category. In June, the Company was named one of Fortune’s “Best Workplaces in Chicago 2022™” for the sixth consecutive year, ranking third overall on the list, and in July as one of Fortune's "Best Workplaces for Millennials" for the third consecutive year. The Company also was recognized by Seramount as a “Top 75 Company for Executive Women” and more recently, as a "Best Company for Multicultural Women." In other environmental, social and governance (ESG) achievements, in May, the Company was recognized in the U.S. PatientView survey of patient groups, ranking second in overall corporate reputation among patients familiar with the Company. Also in May, the Company received an International Corporate Social Responsibility Excellence Award for its #RAREis Adoption Fund.

Second-Quarter Segment Results

Management uses net sales and segment operating income to evaluate the performance of the Company’s two segments, the orphan segment and the inflammation segment. While segment operating income contains certain adjustments to the directly comparable GAAP figures in the Company’s consolidated financial results, such as the exclusion of upfront and milestone payments related to license and collaboration agreements, it is considered to be prepared in accordance with GAAP for purposes of presenting the Company’s segment operating results.

• Second-quarter 2022 net sales of the orphan segment, the Company’s strategic growth segment, were $841.3 million, driven by the growth of TEPEZZA, KRYSTEXXA, UPLIZNA, RAVICTI and ACTIMMUNE. Second-quarter 2022 orphan segment operating income was $315.1 million.

• KRYSTEXXA second-quarter 2022 net sales increased 29% year-over-year driven by higher adoption of KRYSTEXXA with immunomodulation, which now exceeds 50% of new patient starts. In addition, the Company continues to see strong uptake of KRYSTEXXA from both rheumatologists and nephrologists.

   

Inflammation Segment

• Second-quarter 2022 net sales of the inflammation segment were $35.1 million and segment operating loss was $6.6 million. Net sales were impacted by an at-risk launch of generic PENNSAID 2%^® (diclofenac sodium) initiated on May 6, 2022, by Apotex Inc. in the United States.

Cash Flow Statement and Balance Sheet Highlights

• Second-quarter 2022 operating cash flow on a GAAP and non-GAAP basis was $249.2 million and $251.4 million, respectively.
• As of June 30, 2022, the Company had cash and cash equivalents of $1.89 billion.
• As of June 30, 2022, the total principal amount of debt outstanding was $2.60 billion.

Revised 2022 Guidance

The Company now expects full-year 2022 net sales to range between $3.53 billion and $3.60 billion, updated from the previous guidance range of $3.9 billion to $4.0 billion. The Company now expects TEPEZZA full-year 2022 net sales percentage growth in the high-teens, compared to the previous guidance of mid-30s percentage growth. The Company continues to expect KRYSTEXXA full-year 2022 net sales growth of more than 20%. The Company expects inflammation segment second-half 2022 net sales of less than $30 million due to an at-risk launch of a generic PENNSAID 2% initiated on May 6, 2022. Full-year 2022 adjusted EBITDA is now expected to range between $1.30 billion and $1.35 billion, updated from the previous guidance range of $1.63 billion to $1.70 billion.

Note Regarding Use of Non-GAAP Financial Measures

Horizon provides certain non-GAAP financial measures, including EBITDA, or earnings before interest, taxes, depreciation and amortization, adjusted EBITDA, 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 (expense) and tax rate, non-GAAP operating cash flow and certain other non-GAAP income statement line items, 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 exclude, as applicable, acquisition and/or divestiture-related costs, manufacturing plant start-up costs, restructuring and realignment costs, as well as non-cash items such as share-based compensation, inventory step-up expense, depreciation and amortization, non-cash interest expense, goodwill and long-lived assets impairment charges, gain (loss) on equity security investments and sales of assets, 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 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. 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 2022 adjusted EBITDA guidance to expected GAAP net income (loss) guidance because certain items such as acquisition/divestiture-related expenses and share-based compensation that are components of net income (loss) cannot be reasonably projected due to the significant impact of changes in Horizon’s share price, the variability associated with the size and/or timing of acquisitions/divestitures, and other factors. These components of net income (loss) could significantly impact Horizon’s GAAP net income (loss).
