[Form 4] Annexon, Inc. Insider Trading Activity

Rhea-AI Filing Summary

On 07/30/2024, Grindr Inc. (GRND) filed a Form 4 detailing an insider equity award to director and 10% owner George Raymond Zage III. He received 6,669 restricted stock units (RSUs) at no cost. The RSUs vest 25% on 10/30/2025 and the remainder in equal quarterly installments, conditioned on continued service under the 2022 Equity Incentive Plan.

Following the grant, Zage’s direct ownership rises to 6,733,283 common shares. He also maintains indirect control of 85,926,333 shares through Tiga Eighty-Eight Pte Ltd and 1,060,507 shares via Big Timber Holdings LLC. No shares were sold and no derivative positions were reported.

The incremental grant is immaterial relative to Zage’s existing >10% stake and does not alter float or signal operational developments. The filing is principally a routine disclosure of executive compensation and ownership structure.

Insights

SEC Compliance Analyst

TL;DR: Routine RSU award to large shareholder; no market-moving details.

This Form 4 records a small equity incentive—6,669 RSUs—granted to George Zage. It modestly increases his direct holding but leaves his aggregate beneficial ownership effectively unchanged at roughly 93.7 million shares. The zero-cost grant aligns compensation with shareholder value but is far too small to influence governance or control dynamics. Because no dispositions occurred and vesting is long-dated, I view the filing as procedural, not price-sensitive.

Portfolio Manager

TL;DR: De minimis addition; neutral for GRND valuation.

The grant equals <0.01% of GRND’s float and does not change insider ownership concentration. Absence of sales is mildly reassuring, yet the scale is immaterial for earnings, dilution, or float tightening. I do not expect trading impact or need to adjust position sizing based on this disclosure.
