Insights

Corporate Governance Expert

TL;DR: Routine insider sales by CEO/Chairman; filings are timely and include ESPP purchases.

The Form 4 reports that Mac Armstrong, serving as both CEO and Chairman, disposed of 5,000 shares in two transactions on 09/22/2025 and retains significant indirect holdings via the Armstrong Family Trust. The filing includes a footnote disclosing 2,652 shares acquired under the 2019 ESPP and provides weighted-average sale prices and a commitment to supply per-price breakdowns on request. This is a standard Section 16 disclosure; the dual role and large remaining beneficial stake are governance-relevant but the filing itself shows no procedural irregularities.
