The Form 4 reports the conversion/settlement (transaction code M). No cash price or total dollar value is provided in the filing.

Key Details

Transaction date: May 19, 2026; Form 4 filed May 21, 2026 (appears to be timely within the usual two-business-day window).
Transaction code: M (exercise or conversion of a derivative). The filing shows the derivative instrument was converted and the underlying preferred shares were received.
Shares involved: 485 RSUs settled into 485 Series A Preferred shares. Per the filing, one RSU = right to one share of Series A Preferred (footnote F1).
Shares owned after transaction: Not specified in the filing.
Notable footnotes: F2 confirms settlement of RSUs on their scheduled vesting date; F3 explains these RSUs were originally granted by Star Operating Companies, Inc. and exchanged for 485 RSUs in the May 21, 2025 merger agreement, with 100% vesting on May 19, 2026.
No 10b5-1 plan, open-market sale, or tax-withholding sale was reported.

Context

This was a standard award settlement on vesting (conversion of RSUs into preferred shares), not an open-market purchase or sale. Such award settlements are routine compensation events and do not by themselves indicate a buy/sell signal from the insider.
The filing does not disclose a per-share or total dollar amount for the preferred shares, so investors cannot infer the cash value of this settlement from this Form 4.
