Nathaniel Fick was elected by the holders of the Company’s Series B preferred shares to serve as a preferred-stock director effective July 8, 2026 (he concurrently resigned his Class III seat to accept that appointment). On July 9, 2026 the Board appointed Haiyan Song, age 60, as a Class III director to hold office until the 2029 annual meeting.

Key Details

• Dates: Nixon resignation and Fick preferred-stock appointment effective July 8, 2026; Song appointment effective July 9, 2026.

• Committees & compensation: Fick will continue to serve on the Nominating and Corporate Governance Committee and will not be paid for Board service in accordance with his employer’s policies. Song will be compensated per the Company’s Non-Employee Director Compensation Policy: $50,000 annual cash retainer (quarterly) and a $150,000 annual equity retainer in restricted stock units (vesting subject to service; accelerated on change in control).

Why It Matters Board composition and which shareholder groups hold director appointment rights can affect governance oversight and strategic direction. Investors should note the Series B preferred holders exercised their appointment right by placing Nathaniel Fick on the Board, and that Haiyan Song joins as a compensated independent director through 2029. These are governance updates (Item 5.02) rather than financial results, but they could be relevant to investor assessments of board independence and stakeholder influence.
