• Shareholder Meeting Scheduled

  The Annual Meeting of Stockholders is scheduled for June 10, 2026, where shareholders will vote on director elections, auditor ratification, executive compensation, and an amendment to the stock incentive plan.

• Significant Insider Capital Injection Finalized

  Robert W. Duggan (Co-CEO & Chairman) and other related parties purchased approximately $278.5 million in common stock through a private placement in October 2025, finalizing the details of a previously disclosed capital raise. Mr. Duggan's individual purchase was approximately $262 million.

• Executive Compensation Disclosures Highlight Large Figures

  The filing details 'Compensation Actually Paid' for Co-CEOs, including $233.1 million for Dr. Mahkam Zanganeh and $238.0 million for Mr. Manmeet Soni in 2025. These figures are largely driven by non-cash accounting re-measurements of performance-based stock options modified in April 2025, and the company also discloses substantial change-in-control equity acceleration and tax gross-up payments.

• Proposal to Expand Stock Incentive Plan

  Shareholders will vote on a proposal to increase the number of shares authorized for issuance under the 2020 Stock Incentive Plan by 8,000,000 shares. This represents approximately 1.03% potential dilution based on current outstanding shares.

This definitive proxy statement finalizes the agenda for the upcoming annual meeting, detailing several critical proposals and significant financial disclosures. The most impactful elements include a substantial capital injection from key insiders, particularly the Chairman and Co-CEO, which signals strong confidence in the company's future, especially as it navigates a pre-revenue stage with significant losses and a pending BLA decision. However, the filing also reveals extremely high 'Compensation Actually Paid' figures for Co-CEOs, largely due to non-cash accounting re-measurements of equity awards, and outlines substantial change-in-control benefits, which could draw shareholder scrutiny. Furthermore, a material derivative lawsuit alleging fiduciary duty breaches related to $520 million in notes adds a significant layer of legal risk. Investors should weigh the strong insider commitment against the governance concerns and legal challenges.
