Krylov Sergei 4

What Happened
Sergei Krylov, a director of ProFrac Holding Corp. (ACDC), received a grant of 22,421 restricted stock units (RSUs) on May 27, 2026. The RSUs were granted at $0.00 per share (award), with a total grant-date fair value of $150,000 as approved by the Compensation Committee. The RSUs vest in full on May 27, 2027, subject to Krylov’s continued service on the board through the vesting date. This is a compensation award rather than an open-market purchase or sale.

Context
RSU grants to directors are a common form of compensation and do not represent an immediate purchase or sale of stock. The award becomes equity only if and when the RSUs vest and are settled, so this grant does not itself change Krylov’s current share count until vesting (or earlier settlement, if applicable).
