Rhea-AI Filing Summary

Zymeworks Inc. reported preliminary, unaudited cash resources of about $270.6 million as of December 31, 2025, and said that, based on current plans, it believes it can fund operations beyond 2028 assuming full execution of a $125.0 million share repurchase plan and receipt of $440.0 million in anticipated regulatory milestone payments tied to potential Ziihera approvals in GEA across the United States, Europe, Japan and China. The company also announced multiple leadership changes, including appointing Brian Cherry as a new Class II director, terminating Executive Vice President, Chief Business Officer and Chief Financial Officer Leone Patterson without cause, and naming Chair, President and CEO Kenneth Galbraith as interim Chief Financial Officer. Zymeworks promoted Mark Hollywood to Executive Vice President and Chief Operating Officer with increased salary and new equity awards, and outlined a planned transition in the Chief Medical Officer role from Jeffrey Smith, who is retiring, to Sabeen Mekan.

Insights

Biotech equity & governance analyst

Preliminary cash looks solid but cash runway depends on buybacks and milestones, while Zymeworks reshapes several key leadership roles.

Zymeworks cites preliminary, unaudited cash resources of about $270.6 million as of December 31, 2025. It believes this, together with assumptions about a $125.0 million share repurchase plan and $440.0 million in anticipated regulatory milestone payments tied to possible Ziihera approvals in GEA, could fund operations beyond 2028. These figures are described as estimates, subject to internal review and external audit, so they may change once full year results are finalized.

Leadership updates are extensive. The board added Brian Cherry as a Class II director and aligned his equity with the standard non‑employee director plan. Leone Patterson was terminated without cause from her executive roles, and Chair, President and CEO Kenneth Galbraith again assumes interim Chief Financial Officer duties. This combines multiple top positions in one individual until a new CFO is hired, which concentrates responsibilities but maintains continuity.

The company also promoted Mark Hollywood to Executive Vice President and Chief Operating Officer with a higher base salary, larger bonus opportunity and new option, RSU and performance stock unit grants. In medical leadership, long‑time Chief Medical Officer Jeffrey Smith is retiring at the end of January 2026, with Sabeen Mekan becoming Senior Vice President and Chief Medical Officer effective February 1, 2026. Future filings and press releases associated with the attached corporate update and year‑end results will provide more detail on how these financial estimates and leadership shifts translate into execution on the company’s strategic priorities.

Non-Employee Director Compensation Policy

The Board maintains a compensation policy for its non-employee directors providing for cash and equity compensation, the terms of which policy are periodically evaluated and revised based upon advice from the independent compensation consultant to the Board’s compensation committee (the “Compensation Committee”). On January 9, 2026, upon advice from the independent compensation consultant and recommendation from the Compensation Committee, the Board approved an amended and restated non-employee director compensation policy (as amended, the “Amended and Restated Director Compensation Policy”), providing for revised cash and equity compensation to non-employee directors, effective as of January 1, 2026, which changes adjust the Board’s compensation program based in part upon the non-employee director compensation practices of the Company’s peer group. The key revisions effected by the Amended and Restated Director Compensation Policy include the following:

• Beginning January 1, 2026, the annual cash retainer fee for service on the Board increased from $40,000 to $45,000 and the additional annual cash retainer fee for service as Lead Independent Director increased from $25,000 to $30,000.

• The initial equity award for any new non-employee directors, to be granted on or about the time of the director joining the Board, was changed from an option to purchase 62,000 shares of Company common stock to equity awards consisting of an option to purchase 23,000 shares of common stock and 15,400 RSUs. 1/36th of the shares subject to the option will vest on each monthly anniversary of the grant date, subject to the non-employee director’s continued service, and the RSUs will vest as to 1/3 of the underlying shares on each annual anniversary of the grant date, subject to the non-employee director’s continued service.

4

• The annual equity grant to continuing non-employee directors, was changed from an option to purchase 31,000 shares of Company common stock to equity awards consisting of an option to purchase 11,500 shares of common stock and 7,700 RSUs. The options and RSUs each vest as to 100% of the shares subject to the option or the RSUs, as applicable, on the one-year anniversary of the grant date, subject to the non-employee director’s continued service through such date.

As a result of the foregoing amendments, the Amended and Restated Director Compensation Policy provides for the following cash and equity compensation to the Company’s non-employee directors:
