Weave Communications (WEAV) COO receives 300,000-share RSU compensation grant

Rhea-AI Filing Summary

Weave Communications, Inc. reported that Chief Operating Officer Marcus Bertilson received a grant of 300,000 shares of Common Stock in the form of time-based restricted stock units. The award is at no cash cost to him and represents compensation rather than an open‑market purchase.

The RSUs will vest as to 33% of the shares on March 1, 2027, with the remaining shares vesting in equal quarterly installments over the following two years, subject to his continued employment on each vesting date. After this grant, he directly holds 756,343 shares of Common Stock.

His reported holdings include 2,500 shares acquired under the company’s employee stock purchase plan on February 25, 2026, and reflect a small correction to a previously reported number of shares withheld to satisfy tax obligations on earlier RSU settlements.
