[Form 4/A] Mannatech Inc. Amended Insider Trading Activity

Rhea-AI Filing Summary

Erin Barta Kemmler, General Counsel of Mannatech Inc. (MTEX), reported a correction to a previously filed Form 4 and disclosed recent equity activity. The reporting person disposed of 3,000 shares of common stock and was granted 10,000 stock options with an exercise price of $10.60 that convert into 10,000 common shares. After these transactions the reporting person directly beneficially owned 19,000 shares in total.

The amendment clarifies the options' vesting schedule: one-third vests on each anniversary of the grant over three years, with immediate vesting upon a change in control. The Form identifies the transaction date as 06/03/2025 and notes the original filing contained an incorrect vesting schedule.

Insights

Corporate Governance Expert

TL;DR: Amendment fixes vesting disclosure; standard multi-year vesting with change-in-control acceleration reduces ambiguity for shareholders.

The corrected vesting schedule (one-third annual vesting over three years) is a common structure for executive equity awards and clarifies the timing of potential dilution. The explicit acceleration upon a change in control is material to governance because it affects incentive alignment and potential payout timing in an M&A scenario. The disclosure correction improves transparency but does not, by itself, indicate a change in corporate strategy or financial condition.

Securities Analyst

TL;DR: Transaction is routine insider activity: modest share sale and option grant; limited direct impact on valuation.

The disposal of 3,000 shares is modest relative to typical public-company float and the 10,000-option grant at a $10.60 strike represents potential future dilution if exercised. Because the options vest over three years, near-term dilution is limited. The amendment corrects a disclosure error, which is positive for regulatory compliance, but the underlying transactions are not materially transformative for investors based on the data provided.

Explanation of Responses:

1. The Form 4 that was filed on 6/5/2025 was filed with the incorrect vesting schedule. The correct vesting schedule is one-third of the stock options vest on the first anniversary of the date of grant, another one-third of the stock options vest on the second anniversary of the date of grant and the remaining one-third of the stock options vest on the third anniversary of the date of grant.

Remarks:

Options will vest immediately in the event of a change in control.
