• Clear timeline: resignation effective Sept 19, 2025 and appointment effective Sept 22, 2025 reduces transition uncertainty

Negative

• Departure of incumbent CFO Timothy A. Gray creates a leadership change risk effective Sept 19, 2025

Insights

Corporate Governance Specialist

Internal promotion preserves continuity during the CFO transition.

The appointment of Elena Marquez from Vice President of Finance to CFO effective September 22, 2025 signals an internal succession path that can reduce disruption to financial reporting and operations because she already served as Controller since September 2021.

This matters for investors because an internal successor often shortens the learning curve on accounting policies and ongoing projects, and the Board has formally designated her as principal financial and accounting officer under SEC rules.

Compensation & Finance Analyst

Compensation changes are modest and structured for retention.

Ms. Marquez will receive restricted stock units with an aggregate grant date fair value of $250,000, vesting in three equal annual installments, and will be eligible for the Executive Severance Plan.

These elements aim to align incentives and retain the officer; the grant size is disclosed and quantifies near-term dilution pressure tied to equity compensation.
