Insights

Insider Transactions Analyst

Significant insider dispositions recorded over several weeks; a new option exercise sale is planned.

The filing shows a proposed sale of $4,434,403.42 for 21,365 shares via Fidelity Brokerage Services, acquired via an option granted on 04/09/2018 and paid in cash on 10/09/2025. Multiple prior sales by James A. Burke from 09/10/2025 to 10/08/2025 are itemized with gross proceeds for each trade.

The pattern is factual disclosure of insider liquidity rather than a statement about company performance; monitor subsequent Form 4 or Form 5 filings for continuing dispositions or indications of a structured trading plan within the next few weeks.

Corporate Governance Specialist

Disclosure aligns with Rule 144 procedures; no trading-plan date is indicated on this form.

The filer represents compliance with Rule 144 by filing this notice and affirms no known undisclosed material adverse information. The record lists the acquisition source as the issuer and an option grant date, which documents the insider's basis for the sale.

Governance stakeholders should note the absence of a declared Rule 10b5-1 adoption date on the form; if a written trading plan exists, a separate filing or notation would clarify whether sales are pre‑planned within the coming months.
