Buy Plan / Sale Plan: These are also open market purchases/sales of shares, but in this case the transaction is part of a trading plan. Rule 10b5-1 allows insiders to setup a trading plan to buy/sell stocks over a certain period of time. Since the purchases/sales are predetermined, this protects the insiders from violating insider trading law.

Transaction was made pursuant to a contract, instruction or written plan for the purchase or sale of equity securities of the issuer that is intended to satisfy the affirmative defense conditions of Rule 10b5-1(c).

Explanation of Responses:

Id Content
F1 This Form 4/A is being filed to correct the original Form 4 filed on May 15, 2025 ("Original Form 4"). The Original Form 4 inadvertently omitted the reporting of an option exercise that occurred on May 15, 2025, immediately prior to the sale of shares reported in that filing. The number of shares sold as reported in the Original Form 4 was correct; however, the ending total was incorrect due to the omission of the option exercise. This amendment adds the previously unreported option exercise transaction and restates the sell of shares reported in the Original Form 4 in a single combined row, consistent with other filings for the Reporting Owner. No other changes have been made to the Original Form 4.
F2 These transactions occurred automatically pursuant to a plan adopted by the Reporting Person on November 20, 2024 that is intended to satisfy the affirmative defense conditions of Rule 10b5-1(c).
F3 Includes unvested RSUs.
F4 The price reported in Column 4 is a weighted average price. These shares of common stock, par value $0.01 per share ("Common Stock") of Waystar Holding Corp. (the "Issuer") were sold in multiple transactions ranging from $38.89 to $40.06, inclusive. The Reporting Person undertakes to provide to the Issuer, any security holder of the Issuer, or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares of Common Stock sold at each separate price in the range set forth in this footnote.
F5 Options granted August 17, 2020 of which 50% of the option vests in five substantially equal annual installments commencing on August 17, 2021 and the remaining 50% of the option vests upon achievement of certain specified performance-based vesting criteria.
