Rhea-AI Filing Summary

A Form 144 notice reports a proposed sale of up to 127,141 shares of Class A Common stock listed on NASDAQ, with an aggregate market value of $32,743,893.14. The planned sales are to be effected through Morgan Stanley Smith Barney LLC and relate to shares from the exercise of stock options, including 42,443 shares to be exercised on July 13, 2026 and 84,698 shares previously exercised on December 4, 2023. The filing also lists multiple recent sales under a Rule 10b5-1 sales plan for Olivier Pomel in May and June 2026.

Filing Explained

The July 13 Form 144 identifies a proposed disposition of 127,141 Class A shares; it records a planned sale, not a completed one.

The July 13, 2026 Form 144 identifies 127,141 Class A common shares as securities to be sold.

That is a proposed disposition: this filing does not establish that those shares were sold.

The listed securities consist of 42,443 shares from an exercise of stock options on July 13, 2026 and 84,698 shares from stock options previously exercised on December 4, 2023; both entries show cash consideration.

The past-three-month table labels the listed sales as made under a 10b5-1 Sales Plan, except for the 26,012-share sale dated June 2, 2026, which displays no such plan label.

Under the supplied definition, a Rule 10b5-1 plan is adopted in advance and executes trades on a schedule or formula; its disclosure states the adoption date rather than reasons for individual trades.

The relevant unresolved step is whether the proposed July 13, 2026 sale is completed; the filing supplies no completion record.

Form 144 regulatory

"Filer Information | | | 144: Filer Information"

Form 144 is a document that investors must file with the government when they plan to sell a large number of shares of a company's stock. It helps ensure transparency so everyone knows how many shares are being sold and when, which can impact the stock's price.

10b5-1 Sales Plan regulatory

"10b5-1 Sales Plan for OLIVIER POMEL 620 8th Avenue"

A 10b5-1 sales plan is a written, prearranged schedule that company insiders use to buy or sell their employer’s stock under a U.S. securities rule, so trades occur automatically at set times or prices regardless of later private information. It matters to investors because it reduces the risk of insider-trading accusations and signals that certain insider trades were planned ahead—like putting transactions on autopilot—while still affecting share supply and market confidence.
