First Quarter 2024 Financial Highlights

Revenue for the three months ended March 31, 2024, was $752 million, compared to $448 million in the same period of 2023, driven primarily by growth in BRUKINSA product sales in the U.S. and Europe of 153% and 243% respectively.

Product Revenue for the three months ended March 31, 2024, was $747 million, compared to $410 million in the same period of 2023, representing an increase of 82%. The increase in product revenue was attributable to increased sales of our internally developed products, BRUKINSA and tislelizumab. For the three months ended March 31, 2024, the U.S. was the Company's largest market, with product revenue of $351 million, compared to $139 million in the prior year period.

Gross Margin as a percentage of global product revenue for the first quarter of 2024 was 83%, compared to 80% in the prior-year period. The gross margin percentage increased primarily due to proportionally higher sales mix of global BRUKINSA compared to other products in the portfolio.

Research and Development (R D) Expenses increased for the first quarter of 2024 compared to the prior-year period on both a GAAP and adjusted basis primarily due to advancing preclinical programs into the clinic and early clinical programs into late stage. Upfront fees and milestone payments related to in-process R D for in-licensed assets totaled $35 million in the first quarter of 2024, compared to nil in the prior-year period.

Selling, General and Administrative (SG A) Expenses increased for the first quarter of 2024 compared to the prior-year period on both a GAAP and adjusted basis due to continued investment in the global commercial launch of BRUKINSA, primarily in the U.S. and Europe. SG A expenses as a percentage of product sales were 57% for the first quarter of 2024 compared to 80% in the prior year period.

Loss from Operations in the first quarter of 2024 decreased 30% on a GAAP basis and 47% on an adjusted basis compared to the prior-year period. The decrease is driven by significantly improved operating leverage associated with substantial revenue growth and expense discipline as we make significant progress on the path to sustainable profitability.

GAAP Net Loss improved for the quarter ended March 31, 2024, compared to the prior-year period, as our product revenue growth and management of expenses is driving increased operating leverage.

For the quarter ended March 31, 2024, net loss per share were $(0.19) and $(2.41) per American Depositary Share (ADS), compared to $(0.26) per share and $(3.34) per ADS in the prior year period.

Cash Used in Operations for the quarter ended March 31, 2024, totaled $309 million compared to $564 million in the prior-year period, driven by improved operating leverage.

Note Regarding Use of Non-GAAP Financial Measures

BeiGene provides certain non-GAAP financial measures, including Adjusted Operating Expenses and Adjusted Operating Loss and certain other non-GAAP income statement line items, each of which include adjustments to GAAP figures. These non-GAAP financial measures are intended to provide additional information on BeiGene's operating performance. Adjustments to BeiGene's GAAP figures exclude, as applicable, non-cash items such as share-based compensation, depreciation and amortization. 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. BeiGene maintains an established non-GAAP policy that guides the determination of what costs will be excluded in non-GAAP financial measures and the related protocols, controls and approval with respect to the use of such measures. BeiGene believes that these non-GAAP financial measures, when considered together with the GAAP figures, can enhance an overall understanding of BeiGene's 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 BeiGene'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.
