CARNEY LLOYD 4/A

What Happened
Lloyd Carney, a director of Grid Dynamics Holdings, Inc. (GDYN), was awarded 2,309 restricted stock units (RSUs) on December 23, 2025. The RSUs were reported as acquired at $0.00 (no cash exchanged). Each RSU represents a contingent right to one share of common stock; the RSUs are scheduled to vest on March 23, 2026, provided Carney remains a service provider in his board (and applicable committee) roles through that date. This Form 4 is an amendment correcting the originally reported RSU count.

Key Details

• Transaction date and type: 2025-12-23 — Grant/Award (code A) of 2,309 RSUs at $0.00 per unit.
• Vesting: RSUs vest on 2026-03-23, contingent on continued board/committee service (Footnote F2).
• Filing status: This is an amended Form 4; the initial Form 4 was filed on 2025-12-29 to report the transaction and is now corrected (Footnote F1).
• Shares owned after transaction: The filing does not state a total beneficial ownership amount after this grant.
• Holdings notes: Existing shares are held in related trusts and a charitable foundation controlled by Carney (Footnotes F3–F6).
• Transaction code: A = Award/Grant (not a purchase or sale).

Context
RSUs are deferred compensation that convert to actual shares upon vesting; a grant at $0 is standard (no cash outlay). Director RSU awards are routine corporate compensation and do not, by themselves, indicate a buy/sell signal. The amendment corrects an administrative error in the originally reported RSU quantity.
