  • Maintained sole voting and dispositive power over the reported shares

Insights

TL;DR: Beneficial ownership fell below 5%, now 4.96% (641,801 shares); sales are documented on Schedule A.

The filing is a straightforward disclosure that the Reporting Person’s stake in MRKR dropped under the 5% reporting threshold. The key numeric facts are clear: 641,801 shares held and 12,938,910 shares outstanding used for the percentage calculation. The disclosure of sole voting and dispositive power means the trustee retains full control of this stake despite the reduction. No new purchases, control contests, or compensatory arrangements are disclosed here; the change is driven by sales detailed separately on Exhibit A.

TL;DR: Trustee reduced position below 5% and previously resigned from the board; no contractual arrangements disclosed in this amendment.

The filing confirms John R. Wilson’s role as trustee and his prior board resignation on January 24, 2025. The amendment does not identify any ongoing agreements, concerted actor groups, or special arrangements affecting governance rights. Sole voting power is maintained for the reported shares, and no litigation or legal encumbrances are disclosed. The governance implication is limited: ownership fell below the 5% public ownership threshold, triggering this amendment to update prior disclosures.
