Key Business Updates

BRUKINSA (zanubrutinib) is an orally available, small molecule inhibitor of BTK designed to deliver complete and sustained inhibition of the BTK protein by optimizing bioavailability, half-life, and selectivity. With differentiated pharmacokinetics compared with other approved BTK inhibitors, BRUKINSA has been demonstrated to inhibit the proliferation of malignant B cells within a number of disease-relevant tissues. BRUKINSA has the broadest label globally of any BTK inhibitor and is the only BTK inhibitor to provide the flexibility of once or twice daily dosing. The global BRUKINSA clinical development program includes about 6,000 patients enrolled in 30 countries and regions across more than 35 trials. BRUKINSA is approved in more than 70 markets, and more than 100,000 patients have been treated globally.

U.S. sales of BRUKINSA totaled $504 million in the third quarter of 2024, representing growth of 87% over the prior-year period, with more than 60% of the quarter over quarter demand growth coming from expanded use in CLL as BRUKINSA continued to gain share in CLL new patient starts BRUKINSA sales in Europe totaled $97 million in the third quarter of 2024, representing growth of 217%, driven by increased market share across all major markets, including Germany, Italy, Spain, France and the UK

Five-year follow-up results from cohort 1 of the Phase 3 SEQUOIA study showed sustained progression-free survival (PFS) benefit (54-month PFS rate of 80%) with BRUKINSA in patients with treatment-na ve (TN) CLL or small lymphocytic lymphoma (SLL), with no new safety signals observed detailed data will be presented at the annual American Society of Hematology (ASH) 2024 conference and

Third Quarter 2024 Financial Highlights

Revenue for the three months ended September 30, 2024, was $1,002 million, compared to $781 million in the same period of 2023, driven primarily by growth in BRUKINSA product sales in the U.S. and Europe of 87% and 217% respectively. The reacquisition of the full global commercial rights to ociperlimab and TEVIMBRA in the third quarter of 2023 resulted in the recognition of the remaining deferred revenues from the former Novartis collaborations which contributed $183 million of the total revenue in the prior year period.

Product Revenue for the three months ended September 30, 2024, was $993 million, compared to $595 million in the same period of 2023, representing an increase of 67%. The increase in product revenue was primarily attributable to increased sales of BRUKINSA. For the three months ended September 30, 2024, the U.S. was the Company's largest market, with product revenue of $504 million, compared to $270 million in the prior year period. In addition to BRUKINSA revenue growth, product revenues were positively impacted by growth from in-licensed products from Amgen and tislelizumab.

Gross Margin as a percentage of global product revenue for the third quarter of 2024 was 83%, compared to 84% in the prior-year period on a GAAP basis and 85% compared to 84% in the prior-year period on an adjusted basis. The GAAP gross margin percentage decrease compared to the prior-year period was the result of accelerated depreciation expense of $17 million resulting from the move to more efficient, larger scale production lines for tislelizumab, and with a similar amount to be incurred in the fourth quarter related to this move. The adjusted gross margin percentage, which does not include the accelerated depreciation, increased primarily due to proportionally higher sales mix of global BRUKINSA compared to other products in the portfolio.

The following table summarizes operating expenses for the third quarter 2024 and 2023, respectively

The following table summarizes operating expenses for the year-to-date period ended September 30, 2024 and 2023, respectively

Research and Development (R D) Expenses increased for the third 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 $5 million in the third quarter of 2024, compared to $15 million in the prior-year period. Included within GAAP research and development expense for the third quarter of 2024 is $24.9 million of accelerated depreciation expense related to the move of clinical production to larger, more efficient production lines with approximately $2.0 million remaining to be incurred in the fourth quarter.

Selling, General and Administrative (SG A) Expenses increased for the third quarter of 2024 compared to the prior-year period on both a GAAP and adjusted basis due to continued investment to support the global commercial launch of BRUKINSA, primarily in the U.S. and Europe. SG A expenses as a percentage of product sales were 46% for the third quarter of 2024 compared to 61% in the prior year period.

GAAP Income (Loss) from Operations in the third quarter of 2024 operating loss decreased 10% compared to the prior-year period primarily due to increased operating leverage. On an adjusted basis, we generated operating income of $66 million, an increase of $82 million from the prior-year period. GAAP and adjusted loss from operations in the prior-year period benefited from the recognition of the remaining deferred revenues from the Novartis collaboration agreements.

GAAP Net Loss for the quarter ended September 30, 2024 was $121 million, compared to net income of $215 million in the prior-year period. Net income in the prior year period benefited from the non-operating gain of $363 million (pre and after-tax) related to the BMS arbitration settlement and the recognition of the remaining deferred revenues from the Novartis collaboration agreements. Net loss in the period continued to improve sequentially, as our product revenue growth and management of expenses is driving increased operating leverage.

For the quarter ended September 30, 2024, net loss per basic ordinary share was $(0.09) and net loss per basic American Depositary Share (ADS) was $(1.15), compared to net income per basic ordinary share of $0.16 and net income per basic ADS of $2.06 in the prior-year period.

Cash Provided by Operations for the quarter ended September 30, 2024, was $188 million, an increase of $267 million over the prior-year period. The improvement in operating cash flows in the period was primarily driven by improved non-GAAP operating income and favorability in the period from working capital seasonality.
