Insights

Insider Transactions Specialist

Multiple, largely pre-arranged sales by a single reporting person are disclosed.

The filing documents specific dispositions: 03/11/2026 (716 shares), 03/09/2026 (3,360 shares), and three earlier dispositions labeled as 10b5-1 Sales. Each row ties a share count to a dollar amount in the excerpt.

These entries are transactional disclosures under Form 144; the presence of 10b5-1 language indicates some sales were executed under a pre-arranged plan. Subsequent filings or Form 4s would show post-transaction holdings and complete context.

Corporate Governance Advisor

Routine insider dispositions are disclosed; no regulatory outcome or allegation is present.

The excerpt also records 2,000 Restricted Stock Units dated 02/06/2024 listed as issuer securities. The disclosure aligns with standard reporting obligations for officer/director dispositions.

Timing and cash-flow treatment beyond the per-transaction dollar lines are not expanded in the excerpt; further filings may clarify remaining holdings and any tax-withholding mechanics.
