Horizon Therapeutics plc (NASDAQ:HZNP) today announced first-quarter 2023 financial results.

"We generated strong first-quarter performance, with double-digit growth for KRYSTEXXA and UPLIZNA, and saw positive trends in TEPEZZA's leading indicators as we exited the first quarter," said Tim Walbert, chairman, president and chief executive officer, Horizon. "Importantly, we announced positive topline results from our TEPEZZA clinical trial in low CAS and long-duration TED patients, as well as received FDA approval for an update to the TEPEZZA indication that reinforces the potential benefit of TEPEZZA, regardless of disease activity or duration. These important events will help us to ease the access burden so all eligible patients can benefit from TEPEZZA. I am extremely proud of what we have accomplished in a few short months and believe we are well positioned as we prepare to become part of Amgen."

Key Growth Drivers

TEPEZZA: TEPEZZA net sales in the first quarter were $405 million, representing an 18 percent sequential decline compared to the fourth quarter of 2022. Net sales were impacted by seasonality, which the Company typically sees with its infused medicines in the first quarter each year. In addition, the TEPEZZA field-force expansion initiated late in 2022 has not yet substantially impacted net sales. More recently, the Company has seen the expansion drive positive momentum in the business, including increases in new prescribers, patient enrollment forms and patient starts. As new prescribers and patients work through the reimbursement process, the Company expects a more meaningful impact to net sales later in the year.

In April 2023, the Company announced positive topline results from its TEPEZZA Phase 4 clinical trial in patients with low CAS and long-duration TED and received FDA approval for an update to the indication for TEPEZZA that supports its potential benefit in TED, regardless of disease activity or duration. This reinforces the importance of unrestricted access for eligible patients across the full spectrum of TED and creates an opportunity to ease the access burden for patients and physicians and to decrease time to therapy for patients who may benefit from TEPEZZA. The Company plans to present data from the Phase 4 trial at a future medical congress and publish the data in a peer-reviewed medical journal to help educate key stakeholders, including physicians, patients and payors.

KRYSTEXXA: KRYSTEXXA first-quarter net sales were $187 million, representing a year-over-year increase of 33%. Sequentially, net sales declined by 13 percent compared to fourth-quarter 2022 due to seasonality. Strong performance in the first quarter was driven by the continued momentum in both the rheumatology and nephrology market segments, including the adoption of KRYSTEXXA with immunomodulation as the new standard of care following FDA approval in July 2022 for an expanded label to include KRYSTEXXA with methotrexate. The Company's efforts to educate physicians and key stakeholders continues to lead to strong patient growth from both new and existing prescribers across both market segments.

UPLIZNA: UPLIZNA first-quarter 2023 net sales were $53.8 million, representing a year-over-year increase of 77%, driven by continued strong execution. Net sales in the U.S. were $47.2 million, an increase of 87%, and were driven by strong and consistent growth in new prescribers and new patient starts. The Company continues to advance its global expansion strategy with multiple planned international launches in 2023.

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, costs associated with our pending transaction with Amgen Inc., including responding to a second request review of the transaction by the United States Federal Trade Commission, manufacturing facility 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 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.
