Waystar (WAY) Director Vivian Riefberg Receives RSU Award

What Happened
Vivian E. Riefberg, a director of Waystar Holding Corp. (WAY), was granted 10,446 restricted stock units (RSUs) on June 3, 2026. The grant is reported as an award (transaction code A) at $0.00 per unit because RSUs are a contingent right to receive shares upon settlement rather than an open-market purchase. This Form 4 was amended to correct the number of RSUs granted (originally reported as 9,303).

Key Details

• Transaction date: 2026-06-03 (reported on amended Form 4 filed 2026-09-25). Transaction code: A (award/grant).
• Grant: 10,446 RSUs @ $0.00 (each RSU represents the contingent right to one share upon settlement).
• Vesting: RSUs vest on the earlier of (i) June 1, 2027 or (ii) the first regularly scheduled annual meeting of stockholders following the grant date (per footnote).
• Amendment: Filing corrected the grant size from 9,303 to 10,446 RSUs.
• Shares owned after transaction: not specified in the Form 4; filing notes that reported totals include unvested RSUs (footnote F2).
• Timeliness: The amended Form 4 was filed on 2026-09-25 for a 2026-06-03 transaction, indicating a late amendment to correct the record.

Context
RSU grants are common director/compensation awards and do not reflect an immediate buy or sell decision in the market. They convert to actual shares only upon vesting/settlement, so they provide a future potential stake rather than an immediate change in market exposure. The amendment simply corrects the reported grant amount.
