As previously stated in my Initial Mailing Declaration of February 10, 2026, Angeion had received 2 requests for copies of the Longform Notice and Claim Form by phone. 23. From February 11, 2026 through March 11, 2026, Angeion has received 3 additional requests for copies of the Longform Notice and Claim Form by phone. In total, Angeion received 5 requests for copies of the Longform Notice and Claim Form by phone. 24. Angeion mailed or emailed copies of the Longform Notice or Claim Form in response to each of these requests, and will continue to respond to such requests throughout the administration of the Settlement UPDATE ON REPORT OF REQUESTS FOR EXCLUSION AND OBJECTIONS 25. The Postcard Notice and Longform Notice informed potential Class Members that requests for exclusion from the Class were to be mailed and addressed to Applied Therapeutics Securities Settlement, c/o Claims Administrator, 1650 Arch Street, Suite 2210, Philadelphia, PA 19103, such that they are received no later than February 26, 2026. That deadline has passed. 26. Angeion has been monitoring all mail received for the Settlement. As of March 11, 2026, Angeion has received one (1) Request for Exclusion. On February 18, 2026, this request was sent by email to info@APLTSecuritiesSettlement.com, an email account Angeion created to communicate with Class Members concerning the administration of the Settlement. The Claims Administrator responded to this email with instructions from the Longform Notice on how to request exclusion, including the requirement that requests for exclusion be sent by mail. On February 20, 2026, the request was received by USPS Express Mail. A redacted copy of the request is attached hereto as Exhibit 1. 5 Case 1:24-cv-09715-DLC Document 137-1 Filed 03/12/26 Page 7 of 22 27. Class Members seeking to object to the proposed Settlement, the proposed Plan of Allocation and/or Lead Counsel’s Fee and Expense Application were required to submit their objection in writing by mail or delivered such that it was received by the Court and Lead Counsel no later than February 26, 2026. Despite these instructions, Class Members sometimes send objections to the Claims Administrator instead. As of March 11, 2026, Angeion has not received any objections, and is not aware of any objections being filed with the Court. UPDATE ON CLAIMS PROCESS 28. Pursuant to the Preliminary Approval Order, Claims are to be submitted no later than April 8, 2026. ECF No. 127, ¶ 14. As of March 11, 2026, Angeion has received 259 Claims from potential Class Members. 29. Based on our experience administering class action settlements in similar cases of this nature, we anticipate the vast majority of Claims to be submitted on or around the claim filing deadline. During the claims administration process, Angeion will review and process all Claims received, will provide Claimants with an opportunity to cure any deficiency or request judicial review of the denial of their Claims, if applicable, and, with Court approval, will ultimately mail or wire Authorized Claimants their pro rata share of the Net Settlement Fund, as calculated under the Plan of Allocation. ESTIMATE OF ADMINISTRATION FEES 30. As of March 11, 2026, the cost to provide notice and administration services has totaled $29,858.24. Angeion estimates that if the number of Claims filed in this case is similar to the number of Claims filed on other securities class actions, then it will be able to complete notice and administration services for the Settlement through two distributions of the Net Settlement Fund 6 Case 1:24-cv-09715-DLC Document 137-1 Filed 03/12/26 Page 8 of 22 to Authorized Claimants within the $200,000 in Notice and Administration Costs that were authorized by the Court’s Preliminary Approval Order. ECF No. 127 ¶ 27. 31. Angeion respectfully requests that, if the Court includes a cap on Notice and Administration Expenses in its Final Judgment or other Order, that the Court also include a provision to allow Angeion and Lead Counsel to request the payment of additional Notice and Administration Expenses in the event that Notice and Administration Expenses exceed the cap included by the Court. I declare under penalty of perjury that the foregoing is true and correct. Executed this 12th day of March 2026. Dawn M.
