• Option exercise (Code M): 232,537 options with a $3.405 exercise price were converted into an equal number of Class A shares.

Post-transaction ownership:

• Indirect: 378,824 (Freedom Revocable Trust), 332,316 (Freedom Revocable Trust to be transferred), 47,383 (Baszucki Family Foundation), 875 (Baszucki Family Foundation post-sale) and 97,201 (2020 Jan Baszucki Gift Trust).
• Derivatives: 835,015 fully-vested stock options (Expiration 01/23/2030) and 12,406,486 Class B shares convertible 1:1 to Class A shares.

All transactions were executed under a Rule 10b5-1 Plan adopted on 11/04/2024. The filing was signed on 06/18/2025 by attorney-in-fact Mark Reinstra.

Positive

• Rule 10b5-1 plan execution reduces appearance of opportunistic trading and aligns with governance best practices.
• No new share issuance; option exercise and sales are non-dilutive to existing shareholders.
• Substantial remaining holdings (12.4 million Class B shares and 835 k options) maintain management’s long-term alignment.

Negative

• Large insider sale of approximately 321,324 shares (~$32 million) may create negative investor sentiment.
• Reduction in direct ownership to 211,559 shares lowers immediate CEO equity stake.

Insights

Portfolio Manager

TL;DR: CEO sold ~321k shares (~$32 m); large residual holdings remain; selling may pressure sentiment.

The filing confirms sizable insider sales by founder-CEO David Baszucki. Despite exercising low-priced options, he immediately disposed of the acquired shares and additional indirectly-held stock, signaling $32 million in liquidity generation at ~$100.50. While the sales were pre-planned under a 10b5-1 arrangement, such volume can weigh on short-term stock perception. Importantly, Baszucki retains substantial economic exposure—over 12.4 million Class B shares plus 835 k options—so his long-term alignment remains intact. Gifts to charitable entities have no direct market impact but reduce his voting stake marginally. From a portfolio perspective, the action is modestly negative for sentiment yet non-dilutive and not thesis-changing.

Corporate Governance Analyst

TL;DR: Planned sale follows governance best-practice; minimal governance risk.

All trades were executed under a pre-established Rule 10b5-1 plan, mitigating concerns of opportunistic timing. Option exercises used existing grants, so no new share issuance occurred. The CEO’s remaining control—via high-vote Class B stock—remains substantial, preserving existing governance structure. Charitable transfers improve transparency of ownership changes. Overall governance implications are neutral.
