SAN DIEGO, May 3, 2023 - Neurocrine Biosciences, Inc. (Nasdaq: NBIX) today announced its financial results for the first quarter ended March 31, 2023 and provided an update on its 2023 financial guidance.

“INGREZZA’s first quarter results highlight the steady progress we are making to help improve the lives of patients living with tardive dyskinesia, yet we still have a tremendous opportunity to help even more patients for many years to come,” said Kevin Gorman, Ph.D., Chief Executive Officer of Neurocrine Biosciences. “We are executing well across our clinical portfolio and anticipate several important milestones in the months ahead including the August 20th PDUFA date for valbenazine for the treatment of chorea associated with Huntington disease. In addition, we remain on-track for top-line data in the second half of this year for several investigational programs, including crinecerfont for the treatment of pediatric and adult congenital adrenal hyperplasia.”

First QuarterINGREZZA Net Product Sales Highlights:

•INGREZZA first quarter 2023 net product sales were $410 million and grew 36% compared vs. the first quarter 2022

•Record number of new patients received therapy during the first quarter of 2023

First Quarter Financial Highlights:

•First quarter 2023 GAAP net loss and loss per share of $77 million and $0.79, respectively, compared with first quarter 2022 GAAP net income and earnings per share of $14 million and $0.14, respectively

•First quarter 2023 non-GAAP net loss and loss per share of $50 million and $0.51, respectively, compared with first quarter 2022 non-GAAP net income and earnings per share of $30 million and $0.30, respectively

•Differences in first quarter 2023 GAAP and non-GAAP operating expenses compared with first quarter 2022 driven by:

◦Acquired In-Process R&D (IPR&D) expense of $144 million in first quarter 2023 associated with expansion of strategic partnership with Voyager Therapeutics, Inc. (Voyager)

◦Increased R&D expense in support of an expanded and advancing clinical portfolio

◦Increased SG&A expense primarily due to ongoing commercial initiatives, including the deployment of the expanded salesforce in April 2022

•At March 31, 2023, the Company had cash, cash equivalents and marketable securities of approximately $1.1 billion

A reconciliation of GAAP to non-GAAP financial results can be found in Table 3 and Table 4 at the end of this earnings release.

Recent Events:

•On January 8, 2023, we entered into a new strategic collaboration with Voyager, which became effective on February 21, 2023, to acquire the worldwide rights to Voyager’s GBA1 gene therapy program for Parkinson’s disease and other GBA1-mediated diseases and three gene therapy programs directed to rare central nervous system targets for up-front consideration of $175 million.

•In the first quarter of 2023, we provided BIAL with written notice of termination of the license agreement to commercialize and market ONGENTYS® (opicapone), an approved adjunctive therapy for patients with Parkinson's disease, in the United States and Canada. We determined that continued commercialization of ONGENTYS is unsustainable. The termination is anticipated to be effective in December 2023. ONGENTYS is an important, safe and effective adjunctive treatment option for Parkinson’s disease patients. We intend to work with BIAL to ensure an orderly transition of the commercialization of ONGENTYS and to ensure patients have continued access to ONGENTYS.

Non-GAAP Financial Measures

In addition to the financial results and financial guidance that are provided in accordance with accounting principles generally accepted in the United States (GAAP), this press release also contains the following non-GAAP financial measures: non-GAAP R&D expense, non-GAAP SG&A expense, and non-GAAP net income and net income per share. When preparing the non-GAAP financial results and guidance, the Company excludes certain GAAP items that management does not consider to be normal, including recurring cash operating expenses that might not meet the definition of unusual or non-recurring items. In particular, these non-GAAP financial measures exclude: non-cash stock-based compensation expense, loss on extinguishment of convertible senior notes, non-cash interest expense related to convertible debt, non-cash amortization expense related to acquired intangible assets, acquisition-related transaction costs, changes in fair value of equity security investments, changes in foreign currency exchange rates and certain adjustments to income tax expense. These non-GAAP financial measures are provided as a complement to results provided in accordance with GAAP as management believes these non-GAAP financial measures help indicate underlying trends in the Company's business, are important in comparing current results with prior period results and provide additional information regarding the Company's financial position. Management also uses these non-GAAP financial measures to establish budgets and operational goals that are communicated internally and externally and to manage the Company's business and evaluate its performance. The Company provides guidance regarding combined R&D and SG&A expenses on both a GAAP and a non-GAAP basis. A reconciliation of these GAAP financial results to non-GAAP financial results is included in the attached financial information.
