Insights

Executive Compensation Analyst

TL;DR: CEO amended filing corrects option vesting to a standard four-year schedule for 85,000 options at $3.32.

The amendment clarifies an administrative error in the original Form 4 and confirms the award structure: a single grant of 85,000 employee stock options with a $3.32 exercise price and a typical four-year vesting pattern (25% after one year, then quarterly over three years). This is a routine executive equity grant amendment to align disclosure with the actual award terms. The filing is informational and does not report cash proceeds or sales; it updates beneficial ownership disclosure to show 85,000 underlying shares owned directly after the reported transaction.

Corporate Governance Expert

TL;DR: Amendment corrects disclosure; no new material transaction beyond the original grant details.

The Form 4/A addresses a clerical error in vesting schedule disclosure and restates the option terms. From a governance perspective, correcting public filings is standard practice to maintain transparency. The corrected vesting timeline is explicit and aligns with common executive incentive designs. The amendment does not introduce additional transactions or changes to ownership beyond clarifying vesting mechanics.
