Key takeaways

Full analysis

The separation of CEO Timothy Go finalizes leadership uncertainty that began with his voluntary leave on February 17, 2026, when the Board appointed Franklin Myers as interim CEO and President. The Separation and Release Agreement, detailed in Exhibit 10.1, includes mutual releases of claims and Mr. Go's commitment to ongoing confidentiality, non-competition, and non-solicitation obligations. Severance compensation totals $4.735 million in cash plus health benefits continuation, providing a structured payout over 12 months contingent on compliance. Equity treatment accelerates vesting for specific portions of his outstanding awards under the 2020 LTIP: full vesting for portions of 2024, 2025, and 2026 RSUs totaling 29,616 units, and pro-rata outstanding PSUs totaling 163,609 units that remain performance-contingent. Remaining awards are forfeited. Investors should note the ongoing situation with CFO Atanas Atanasov, on leave since February 24, 2026, with no separation agreement finalized, potentially signaling further executive changes.
