Insights

Securities Analyst

TL;DR: Amendment corrects a modest overstatement in reported shares; no new transactions disclosed.

The filing is a technical amendment that adjusts the reported beneficial ownership downward by 961.9957 shares to a total of 9,377.366 shares held directly. There are no derivative holdings reported and no new acquisitions or dispositions disclosed in this amendment. For investors, this represents a housekeeping correction to disclosure records rather than a change in ownership or corporate control. The timing shows the original Form 3 was filed on 01/05/2024 and the amendment was executed on 08/14/2025 by an attorney-in-fact.

Corporate Governance Expert

TL;DR: Correcting disclosure improves accuracy; the amendment raises minor governance record-keeping questions.

The amendment indicates the reporting person is an Executive Vice President and corrects an earlier overstatement in filings (Forms 3, 4, 5). While the corrected amount (961.9957 shares) is specific, the filing does not state the cause of the overstatement. The correction itself is a positive step for compliance, but the delay between the original filing date and the amendment could prompt internal review of reporting processes. No material transactions or changes in ownership percentage are disclosed.
