What Happened

Harbour Austin, Chief Financial Officer of ProFrac Holding Corp. (ACDC), was granted 270,000 performance‑based restricted stock units (RSUs) on April 7, 2026. The grant price is $0.00 (no cash paid). These RSUs represent the contingent right to receive one share of Class A common stock per RSU if specified performance and employment conditions are later met.

Key Details

Transaction date: 2026-04-07; filing date: 2026-04-09 (timely).
Transaction type/code: Award/Grant (A); shares acquired: 270,000; acquisition price: $0.00.
Shares owned after transaction: Not disclosed in this Form 4.
Vesting conditions (from filing footnote): RSUs vest only after April 7, 2027 and only if VWAP thresholds are met: 10% at $7.00, 25% at $10.00, 25% at $14.00, 40% at $18.00 (VWAP = 30‑trading‑day average). The reporting person must also remain continuously employed and in good standing on each vesting date.

Context

These are performance‑based RSUs, not an immediate stock purchase or sale. They confer a contingent right to receive shares in the future if both stock‑price (VWAP) targets and continued employment requirements are satisfied. Because vesting is tied to future conditions, there is no immediate transfer of shares or cash proceeds to the insider.
