Schremser Christopher L. 4

What Happened
Christopher L. Schremser, Chief Technology Officer of Waystar Holding Corp., was granted 87,413 restricted stock units (RSUs) on 2026-03-09. The filing shows the acquisition price as $0.00 (standard for RSU grants), so there was no cash exchanged at grant. These RSUs are a grant/award rather than an open-market purchase or sale.

Key Details

• Transaction date: 2026-03-09; Form 4 filed 2026-03-11 (appears timely under the SEC’s two-business-day rule).
• Grant: 87,413 RSUs @ $0.00 (acquisition code A). Total immediate cash value reported: $0.
• Vesting: The RSUs vest in four equal annual installments from the initial grant date through March 1, 2030 (footnote F1). Each RSU represents a contingent right to one share upon settlement.
• Unvested: The award includes unvested RSUs (footnote F2).
• Shares owned after transaction: Not specified in the provided filing.

Context
RSU grants are commonly used for retention and long-term incentive compensation; they do not provide shares or liquidity until vested and settled. Because this is an award (not a purchase or sale), it does not directly signal buying or selling sentiment by the insider.
