ACOSTA JACK L 4

What Happened
Jack L. Acosta, a director of Rimini Street, had 55,727 restricted stock units (RSUs) vest and be converted/exercised on June 2, 2026 (reported as exercise/conversion, code M). The Form 4 shows both an acquisition and a corresponding disposition of those 55,727 RSU-derived interests on 6/2/2026 (exercise price reported as $0.00). On June 3, 2026 he was granted/awarded 44,117 new RSUs (reported as an award, code A) at $0.00 that will vest subject to continued board service.

Key Details

• Transaction dates and codes: 6/2/2026 — exercise/conversion of 55,727 RSUs (M, acquired and disposed); 6/3/2026 — grant of 44,117 RSUs (A, acquired).
• Price: Exercise/award price shown as $0.00 in the filing (RSUs convert to shares without a purchase price).
• Footnotes: F1 = each RSU converts to one share on vesting. F2 = the 55,727 RSUs were awarded 6/4/2025 and 100% vested on 6/2/2026. F3 = the 44,117 RSUs will vest on the earlier of 6/3/2027 or the day before the 2027 annual meeting, contingent on continued board service.
• Shares owned after transaction: the filing does not list total shares owned following these transactions.
• Filing timeliness: Form 4 was filed on 6/4/2026 for transactions occurring 6/2–6/3/2026 — this appears to be a timely filing (not marked late).

Context
RSUs are compensation awards that convert into common shares when they vest; the 6/2 entries reflect vesting/conversion of prior RSUs rather than an open-market cash purchase. The disposition entry on 6/2 indicates the vested derivative interest was recorded as disposed per the Form 4, but the filing does not explicitly state whether shares were sold, withheld for taxes, or otherwise transferred. The 44,117 RSU award granted 6/3/2026 represents future compensation contingent on continued board service and does not by itself indicate a buy/sell signal.
