Zymeworks Provides Corporate Update and Reports Second Quarter 2026 Financial Results Zymeworks Provides Corporate Update and Reports Second Quarter 2026 Financial Results GlobeNewswire August 06, 2026

VANCOUVER, British Columbia, Aug. 06, 2026 (GLOBE NEWSWIRE) -- Zymeworks Inc. (Nasdaq: ZYME), a biotechnology company managing a portfolio of licensed healthcare assets, while developing a diverse pipeline of novel, multifunctional biotherapeutics, today reported financial results for the second quarter ended June 30, 2026 and provided a summary of recent business highlights. In light of the previously announced proposed acquisition of Theravance Biopharma, the Company has elected not to host a second quarter earnings conference call after release of its financial results.

“The first half of 2026 has been a transformative period for Zymeworks, demonstrating the continued evolution of our business into a diversified, revenue-generating biotechnology business. While scientific innovation remains our foundation, we believe long-term value is created not only through discovering new medicines, but also through disciplined capital allocation, creative business development and thoughtful partnership structures that maximize the impact of that innovation for patients and shareholders,” said Kenneth Galbraith, Chair and Chief Executive Officer of Zymeworks.

“The second half of 2026 has the potential to continue creating meaningful value for both patients and shareholders. Subject to regulatory approval and customary closing conditions, the August U.S. PDUFA target action date for zanidatamab and the planned closing of the Theravance Biopharma acquisition, respectively, would immediately strengthen our revenue base and cash flow outlook. This includes a $250 million approval milestone for zanidatamab in the U.S. with up to $190 million in additional potential global regulatory milestones. These diverse royalty and milestone cash flows improve our ability to sustain long-term investment in our wholly-owned R&D pipeline, pursue additional strategic acquisitions and partnerships, and continue returning capital to shareholders through our share repurchase program. We believe this disciplined approach to compounding capital and innovation is what will differentiate Zymeworks over the long term.”

Zanidatamab

Our royalty revenue from Jazz Pharmaceuticals (Jazz) and BeOne Medicines was $1.8 million in the three months ended June 30, 2026, driven primarily by net product sales of Ziihera by Jazz in the United States.

Maintaining Financial Flexibility

Cash Resources: Zymeworks reported $322.5 million in cash, cash equivalents and marketable securities as of June 30, 2026

Share Repurchase Program: In May 2026, the Board of Directors authorized a 2026 share repurchase program under which the Company may repurchase up to $125.0 million of its outstanding common stock, par value $0.00001 per share. As of August 4, 2026, the Company has utilized approximately $49.4 million of this current approved repurchase program to acquire 1,971,454 shares at an average price of $25.04 per share (exclusive of commission expense and estimated excise tax).

Since initiating its share repurchase program in August 2024, the Company has cumulatively utilized $213.6 million to reacquire 10,571,316 shares at an average price of $20.21 per share (exclusive of commission expense and estimated excise tax). As of August 4, 2026, the Company had approximately 71.0 million common shares outstanding.

Operating Expense Discipline: The Company expects significant near-term milestones, including the anticipated closing of the Theravance Biopharma acquisition and the upcoming August 25, 2026 PDUFA date for zanidatamab in GEA, each of which has the potential to immediately expand the Company's revenue and cash flow profile, subject to customary closing conditions and regulatory approval, respectively. The Company continues to expect disciplined investment across research and development and general and administrative activities through the anticipated closing of the Theravance Biopharma acquisition. The Company's previously communicated operating expense framework was established prior to entering into the definitive acquisition agreement, and therefore does not reflect the expected operating profile of the combined organization. Subject to the successful completion of the transaction, the Company expects to provide an updated financial outlook following closing that reflects the combined business.

Financial Results for the Quarter Ended June 30, 2026

The key financial highlights for our 2026 second quarter results are as follows:

Revenue – Total revenue was $4.6 million in 2Q-2026, compared to $48.7 million for the same period in 2025. The decrease was driven mainly by absence of significant non-recurring collaboration revenue recognized in 2026, as well as continued declines in development support and drug supply revenue from Jazz. Revenue in the current‑year period reflects ongoing collaboration activity and increased royalty revenue, which is expected to grow over time as commercial sales of Ziihera® increase.

Research and Development (R&D) Expenses – R&D expenses were $27.4 million in 2Q-2026, compared to $34.4 million for the same period in 2025, primarily reflecting reduced spending on later‑stage and discontinued programs, as well as an overall decrease in spending for earlier‑stage programs and research platforms. R&D expenses in 2Q-2026 were 20% lower than in 2Q-2025, consistent with our planned reduction in R&D expenses in 2026.

General and Administrative (G&A) Expenses – G&A expenses were $19.3 million in 2Q-2026, compared to $15.0 million for the same period in 2025. The increase was primarily driven by higher non-cash stock-based compensation expense. This increase was partially offset by decrease in software amortization and software subscription expenses.

Other Income, net – Net other expense was $3.1 million in 2Q-2026, compared to net other income of $2.8 million for the same period in 2025. The change was driven primarily by $6.6 million of interest expense related to the royalty-backed note financing arrangement with Royalty Pharma executed in March 2026.

Net Loss – Net loss was $45.0 million in 2Q-2026, compared to a net income of $2.3 million for the same period in 2025. The change in 2026 was primarily due to a decrease in revenue, driven by the non-recurring clinical milestones earned in 2Q-2025 and interest expense related to the royalty-backed note financing arrangement with Royalty Pharma. This was partially offset by decrease in total operating expenses.

Liquidity – As of June 30, 2026, we had $322.5 million of cash resources consisting of cash, cash equivalents and marketable securities, comprised of $179.4 million in cash and cash equivalents and $143.1 million in marketable securities. In light of the Company's expected transition to a revenue-generating business supported by multiple anticipated recurring cash flow streams, the Company no longer intends to provide cash runway guidance. Going forward, the Company expects to focus its financial outlook on metrics that more appropriately reflect the operating performance and growth of the business.

Explanation of Non-GAAP Financial Information

In addition to reporting financial information in accordance with U.S. generally accepted accounting principles (GAAP) in this press release, we have elected to present selected non-GAAP, or adjusted, financial measures on a forward-looking basis. Zymeworks believes that estimated adjusted gross operating expense, adjusted research and development expense, and adjusted general and administrative expense, which are non-GAAP financial measures, may be helpful to investors because they provide consistency and comparability with financial performance across periods. These non-GAAP financial measures are not defined by GAAP and should not be considered as alternatives to operating expenses, research and development expenses, and general and administrative expenses or any other indicators of Zymeworks’ performance required to be reported under GAAP. In addition, other companies, including companies in Zymeworks’ industry, may calculate similarly titled non-GAAP or adjusted measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of adjusted gross operating expense, adjusted research and development expense, and adjusted general and administrative expense as financial measures. Investors and others are encouraged to review Zymeworks’ financial information in its entirety and not rely on a single financial measure. As defined by Zymeworks, adjusted gross operating expense represents the aggregate of adjusted research and development expense and adjusted general and administrative expense, each of which excludes stock-based compensation expense for equity- and liability-classified equity instruments. Zymeworks excludes stock-based compensation expense, which is a non-cash expense, because Zymeworks believes that excluding this item provides meaningful supplemental information regarding operational performance.

A reconciliation of historical adjusted gross operating expense, adjusted research and development expense, and adjusted general and administrative expense to the most directly comparable GAAP measures is set forth below. A reconciliation of anticipated adjusted gross operating expense, adjusted research and development expense, and adjusted general and administrative expense to the most directly comparable GAAP measures is not available without unreasonable effort due to the uncertainty of expenses that may be incurred in the future, and we are also unable to predict the probable significance of such adjusted measures. Accordingly, in reliance on the exception provided by Item 10(e)(1)(i)(B) of Regulation S-K, we have not provided a reconciliation for the adjusted gross operating expense, adjusted research and development expense, and adjusted general and administrative expense guidance provided in this press release.
