Centurion Acquisition Converts Class B Shares to Class A Following Governance Updates

The filings referenced include explicit Form 4/5 procedural language stating they are "Filed pursuant to Section 16(a) of the Securities Exchange Act of 1934 or Section 30(h) of the Investment Company Act of 1940," along with a reminder checkbox for when the reporting person is "no longer subject to Section 16."
The Form 4 instructions also require that companies "Report on a separate line for each class of securities beneficially owned directly or indirectly," underscoring that multi-class structures (like Class A vs. Class B) must be treated distinctly in beneficial ownership disclosures.
The form language includes a specific box for disclosures tied to trading-plan safe harbors, stating: "Check this box to indicate that a transaction was made pursuant to a contract, instruction or written plan... intended to satisfy the affirmative defense conditions of Rule 10b5-1(c)."
For the governance-document changes involving Centurion’s ordinary shares, the accompanying explanatory text highlights that amended charter documents can affect more than voting/control—specifically "purpose, share structure, voting rights and how decisions are made," and it notes investor attention to potential changes in "dividend policy and takeover protections."
Centurion Acquisition Corp. director Mickie Rosen converted 30,000 Class B "founder shares" into Class A ordinary shares on June 8, 2026, according to Stock Titan. The one-for-one swap was part of a coordinated move by four board members — Rosen, Vu, Foresman, and Jesselson — ahead of a critical shareholder vote on extending the SPAC's life by another year.
The conversion comes as Centurion races to avoid liquidation. The company holds more than $250 million in a trust account and needs shareholder approval to push its business combination deadline from June 12, 2026, to June 12, 2027, according to Stock Titan.
Rosen and three fellow directors each converted exactly 30,000 Class B shares into Class A shares on June 8, 2026. Separately, Centurion Sponsor LP converted its full 7,067,500 Class B shares into Class A on the same date. The moves effectively collapse the company's dual-class share structure before the June 12 Extraordinary General Meeting.
Class B "founder shares" are typically held by a SPAC's sponsor and early insiders. They normally convert to Class A only after a merger closes. By converting early, the directors now hold the same share class as ordinary public investors — a signal analysts read as a show of commitment to the extension vote.
Centurion postponed its shareholder meeting from June 9 to June 12 to allow more time for investor outreach, according to GlobeNewswire. On June 11, the company locked in non-redemption agreements with holders of 4,675,000 Class A shares — meaning those investors agreed not to cash out their shares before the vote.
If shareholders approve the extension, Centurion gets until June 2027 to close a merger. If they do not, the trust account is liquidated and investors get their money back. The $250 million pool gives the company significant leverage to attract a merger target over the next 12 months.
Governance analysts at Boardroom Alpha view the conversions as a strategy to show that insiders are "in the same boat" as public shareholders. Because Class A shares are publicly traded and Class B are not, converting is a step toward liquidity — even if no shares were sold on June 8.
Critics see it differently. Class B shares typically carry lock-up restrictions. Converting them to Class A is the first step toward a potential open-market sale. The SEC Form 4 filings confirm no Rule 10b5-1 trading plan was in place, suggesting the conversions were a deliberate structural election rather than a pre-scheduled sale, according to Stock Titan.
The Centurion filings landed alongside a wave of equity disclosures from other companies. Red Rock Resorts reported that President Scott Kreeger received 45,130 restricted shares on June 11, 2026, vesting 25% per year over four years starting June 11, 2026. Archer Aviation disclosed that five executives received a combined 464,000 shares through RSU vesting in March, with tax-withholding filings continuing into June.
All filings were submitted under SEC Section 16(a), which requires corporate insiders to publicly report any changes in ownership within two business days. The rules also require companies to list each share class separately — which is why Centurion's Class A and Class B conversions appear as distinct line items in the public record.
