Key Details

• Transaction date: December 9, 2025; Amendment filed: February 6, 2026.
• Grant: 24,741 RSUs; reported acquisition price: $0.00 (compensation grant).
• Shares owned after transaction: not disclosed in the amended filing.
• Footnote: RSUs vest 1/12th quarterly on each June 30, Sept 30, Dec 30 and March 30 following Dec 9, 2025, subject to continued service (per filing).
• Remarks: The Feb 6, 2026 filing amends the original Form 4 (filed Dec 9, 2025) to correct a misstated share count due to administrative error.

Context This was a compensatory award to a director, not an open-market purchase or sale. RSU grants are common for executive/director compensation and vest over time based on continued service; they do not by themselves indicate immediate buying or selling pressure. The amendment corrects reporting accuracy but does not change the nature of the grant.
