Insights

Insider Transactions Analyst

Notice shows an executive-associated sale of 4,000 shares on record.

The filing documents a proposed sale of 4,000 common shares tied to options granted on 03/14/2019. The recorded past sale on 12/23/2025 lists proceeds of $1,032,440.40, indicating a sizable per-share value in that transaction.

Timing and cash‑flow treatment are specific to the listed entries; subsequent filings may show actual settlement details. The broker is Fidelity Brokerage Services LLC.

Corporate Governance Analyst

Routine Section 144 notice consistent with an option-related disposition.

The record links the shares to options and lists the sale method as cash. The presence of an option grant date (03/14/2019) is factual context on the origin of the shares rather than a change in corporate policy.

Because this is a notice of proposed sale, actual impact depends on settlement details in follow-up disclosures. Governance implications hinge on whether transactions follow pre-existing plans or ad-hoc dispositions.
