Insights

Securities Compliance Counsel

Form 144 reports a proposed sale of vested restricted shares and a recent sale by an insider.

The filing lists 10,949 Class A shares "To Be Sold" that vested on 02/17/2026, with Fidelity Brokerage Services named as broker. It also records a prior disposition of 54,786 shares by Tosha Perkins on 03/05/2026 for $353,972.34.

Compliance depends on Rule 144 conditions (holding period, public information, volume limits); the form documents broker and transaction dates, but does not restate Rule 144 eligibility details. Subsequent filings may disclose sale completion and proceeds allocation.

Equity Compensation Analyst

Compensation-related vesting generated a sale notice for 10,949 Class A shares.

The 10,949 shares are described as "Restricted Stock Vesting" with an issuer source of compensation on 02/17/2026. This establishes the grant/vesting origin of the shares being reported for sale.

Prior activity shows a 54,786-share disposition earlier in March; together these items indicate post-vesting sales activity, but the filing does not quantify total post-transaction holdings or exercise balances.
