[Form 4] Ambac Financial Group, Inc. Insider Trading Activity

Rhea-AI Filing Summary

National Vision Holdings (EYE) Form 4 filing: On 07/08/2025, Mark Banner, President of the America’s Best segment, converted 11,728 restricted stock units (RSUs) into common stock (transaction code M). To satisfy withholding taxes, 3,462 shares were surrendered at $24.73 (code F), resulting in a net increase of 8,266 directly owned shares. Banner now directly holds 8,266 common shares and still has 64,575 unvested RSUs scheduled to vest in equal installments over the next two years. The gross value of the withheld shares is roughly $204 k, making this a routine equity-settled award rather than an open-market transaction.

Positive

• Officer increased direct ownership by 8,266 shares, suggesting continued alignment with shareholders.
• 64,575 RSUs remain unvested, providing further long-term incentive for performance.

Negative

• None.

Insights

Securities Analyst

TL;DR – Routine RSU conversion; small net share increase, limited market impact.

The Form 4 shows Banner exercising 11.7 k RSUs granted in 2024 and retaining the resulting stock after paying taxes in kind. Because the shares were not sold into the market, the filing does not signal bearish sentiment. The dollar value (~$204 k net) is modest relative to EYE’s float and market capitalization, so dilution is immaterial. Banner’s remaining 64.6 k RSUs indicate continued alignment with shareholders, but the transaction itself does not change the company’s fundamentals or outlook. Overall, I classify the disclosure as neutral for investors.
