Full Year 2026 Guidance
BeOne’s financial guidance is summarized below:

| FY 2026 1
Total revenue | $6.2 - $6.4 billion
GAAP gross margin % | High-80% range
GAAP operating expenses 2 (combined R&D and SG&A) | $4.7 - $4.9 billion
GAAP operating income 2 | $700 - $800 million
Non-GAAP operating income 2,3 | $1.4 - $1.5 billion

1 Assumes January 1, 2026 foreign exchange rates.
2 Does not assume any potential new, material business development activity or unusual/non-recurring items.
3 Non-GAAP operating income is a financial measure that excludes from the corresponding GAAP measure costs related to share-based compensation, depreciation and amortization expense. Guidance assumes that Non-GAAP expenses track overall expense growth.
BeOne’s total revenue guidance for full year 2026 of $6.2 billion to $6.4 billion includes expectations for strong revenue growth driven by BRUKINSA’s U.S. leadership position and continued global expansion in both Europe and other important rest of world markets. Gross margin percentage is expected to be in the high-80% range and includes the impact of product mix and a full year of 2026 productivity improvements. Guidance for combined operating expenses on a GAAP basis includes expectations of investment to support growth in both commercial and research at a pace that continues to deliver meaningful operating leverage.
The Company is providing the following additional guidance on items impacting net income and earnings per ADS:
•Other income (expense): estimated range of $25 million to $50 million in expense, includes interest amortization from Royalty Pharma arrangement.
•Income tax outlook: earnings may provide sufficient positive evidence to reverse certain valuation allowances in 2026, resulting in a material tax benefit when recognized; the timing and magnitude of a potential reversal is uncertain; prior to reversal, income tax expense should trend with earnings per historical relationship.
•Diluted ADS outstanding: the Company expects diluted ADSs outstanding of approximately 118 million.

Note Regarding Use of Non-GAAP Financial Measures
BeOne provides certain non-GAAP financial measures, including Adjusted Operating Expenses, Adjusted Operating Loss, Adjusted Net Income, Adjusted Earnings Per Share, Free Cash Flow 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 BeOne’s operating performance. Adjustments to BeOne’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. Non-GAAP adjustments are tax effected to the extent there is U.S. GAAP current tax expense. The Company currently records a valuation allowance on its net deferred tax assets, so there is no net impact recorded for deferred tax effects. BeOne 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. BeOne believes that these non-GAAP financial measures, when considered together with the GAAP figures, can enhance an overall understanding of BeOne’s operating performance. The non-GAAP financial measures are included with the intent of providing investors with a more complete understanding of BeOne’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 BeOne’s management uses for planning and forecasting purposes and measuring BeOne’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 BeOne may be calculated differently from, and therefore may not be comparable to, non-GAAP financial measures used by other companies.

1.Tax effect of Non-GAAP adjustments is based on the statutory tax rate in the relevant tax jurisdiction. Please note that the Company currently records a valuation allowance on its net deferred tax assets, so there is no net impact recorded for deferred tax effects.
2.For the fourth quarter of 2024, GAAP diluted loss per ADS includes $0.04 loss per ADS attributable to the dilutive ADS outstanding for purposes of this reconciliation. As the Company was in a GAAP net loss position no diluted weighted average shares outstanding were calculated for US GAAP purposes.
