Exhibit 99.1

BeOne Medicines Announces First Quarter 2026 Financial Results and Business Updates

•Total global revenues of $1.5 billion for the first quarter, an increase of 35% from the prior year

•Foundational BRUKINSA (zanubrutinib) global revenues of $1.1 billion for the first quarter, an increase of 38% from the prior year

•Diluted GAAP Earnings per American Depository Share (ADS) of $1.96 for the first quarter; non-GAAP diluted Earnings per ADS of $3.24 for the first quarter

SAN CARLOS, Calif. – May 6, 2026 – BeOne Medicines Ltd. (NASDAQ: ONC; HKEX: 06160; SSE: 688235), a global oncology company, today announced financial results and corporate updates from the first quarter of 2026.

John V. Oyler, Co-Founder, Chairman, and CEO, BeOne, said:

“These strong first-quarter results reinforce BeOne’s continued growth as a global oncology leader, driven by disciplined commercial execution, and underpinned by our established hematology leadership, and an impressive, rapidly emerging solid tumor pipeline. The sustained competitive advantages of our global superhighway for clinical development and manufacturing are now clear. BRUKINSA has firmly established itself as the foundational, best-in-class BTK inhibitor with unmatched long-term efficacy and safety data for the treatment of CLL and as the only BTKi with proven efficacy superiority over ibrutinib which has resulted in clear global revenue leadership. The fixed-duration combination of sonrotoclax, a foundational, next-generation BCL2 inhibitor, and BRUKINSA represents a potential new standard-of-care in first-line CLL, with BTK CDAC BGB-16673 emerging as a potential first-in-class therapy in the relapsed or refractory setting. With more than 20 abstracts across our hematology and solid tumor pipeline accepted for presentation at ASCO, BeOne has solidified its position as a leading oncology company.”

Exhibit 99.1

First Quarter 2026 Financial Results

Product Revenue totaled $1.5 billion for the first quarter of 2026, representing growth of 34% compared to the prior-year period.

•BRUKINSA: Global sales totaled $1.1 billion for the first quarter of 2026, representing growth of 38% compared to the prior-year period; U.S. sales of BRUKINSA totaled $761 million in the first quarter of 2026, representing growth of 35% compared to the prior-year period.

•TEVIMBRA (tislelizumab): Global sales totaled $206 million in the first quarter of 2026, representing growth of 20% compared to the prior-year period.

•Amgen in-licensed products: Global sales totaled $142 million in the first quarter of 2026, representing growth of 25% compared to the prior-year period.

Gross Margin as a percentage of global product sales for the first quarter of 2026 was 89%, compared to 85% in the prior-year period on a GAAP basis. The gross margin percentage increased due to a proportionally higher sales mix of global BRUKINSA compared to other products in our portfolio. Gross margin also benefited from productivity improvements resulting in lower costs for both BRUKINSA and TEVIMBRA.

Operating Expenses

The following table summarizes operating expenses for the first quarter of 2026:

GAAP Non-GAAP

(unaudited, in thousands, except percentages) Q1 2026 Q1 2025 % Change Q1 2026 Q1 2025 % Change

Research and development $ 541,224  $ 481,887  12  % $ 465,904  $ 421,195  11  %

Selling, general and administrative $ 555,097  $ 459,288  21  % $ 471,993  $ 395,511  19  %

Total operating expenses $ 1,096,321  $ 941,175  16  % $ 937,897  $ 816,706  15  %

Research and Development (R&D) Expenses increased for the first quarter of 2026 compared to the prior-year period on both a GAAP and adjusted basis due to advancing preclinical programs into the clinic and early clinical programs into late stage.

Selling, General and Administrative (SG&A) Expenses increased for the first quarter of 2026 compared to the prior-year period on both a GAAP and adjusted basis due to continued investment to support commercial growth. SG&A expenses as a percentage of product sales were 37% for the first quarter of 2026, compared to 41% in the prior-year period.

Net Income and Basic/Diluted Earnings Per Share

GAAP net income for the first quarter of 2026 was $227 million, an increase of $226 million over the prior-year period, primarily attributable to revenue growth and improved operating leverage.

For the first quarter of 2026, basic and diluted earnings per share were $0.16 and $0.15 per share and $2.05 and $1.96 per American Depositary Share (ADS), compared to basic and diluted earnings per share of $0.00 per share and $0.01 per ADS in the prior-year period.

Free Cash Flow for the first quarter of 2026 was $161 million, representing an increase of $173 million over the prior-year period.

Updated Full Year 2026 Guidance

BeOne’s financial guidance is summarized below:

Prior FY 2026 Guidance

Current FY 2026 Guidance1

Total revenue $6.2 - $6.4 billion $6.3 - $6.5 billion

GAAP gross margin % High-80% range High-80% range

GAAP operating expenses2

(combined R&D and SG&A)

$4.7 - $4.9 billion $4.7 - $4.9 billion

GAAP operating income2

$700 - $800 million $750 - $850 million

Non-GAAP operating income2,3

$1.4 - $1.5 billion $1.45 - $1.55 billion

1 Assumes May 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 $6.3 billion to $6.5 billion includes expectations for strong revenue growth driven by BRUKINSA’s leadership position in the U.S. 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. See Form 10-Q for additional updates on income tax uncertainties.

•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.
