Item 1 Comment:
This Amendment No. 5 (this "Amendment No. 5") amends and supplements the statement on Schedule 13D originally filed by the Reporting Persons on September 7, 2021 (the "Schedule 13D"), as amended by Amendment No. 1 to the Schedule 13D filed by the Reporting Persons on September 18, 2023 (the "Amendment No. 1"), Amendment No. 2 to the Schedule 13D filed by the Reporting Persons on December 5, 2024 (the "Amendment No. 2"), Amendment No. 3 to the Schedule 13D filed by the Reporting Persons on January 10, 2025 (the "Amendment No. 3"), and Amendment No. 4 to the Schedule 13D filed by the Reporting Persons on June 17, 2025 (the "Amendment No. 4" and, together with the Schedule 13D, Amendment No. 1, Amendment No. 2, Amendment No. 3, Amendment No. 4 and this Amendment No. 5, this "Statement"). Unless otherwise indicated, each capitalized term used but not defined in this Amendment No. 5 shall have the meaning assigned to such term in the Schedule 13D, Amendment No. 1, Amendment No. 2, Amendment No. 3 and Amendment No. 4. Except as otherwise specifically amended in this Amendment No. 5, items in the Schedule 13D, Amendment No. 1, Amendment No. 2, Amendment No. 3 and Amendment No. 4 remain unchanged. | ||
| Item 4. | Purpose of Transaction | |
Item 4 of the Statement is hereby amended and supplemented by adding the following: On March 27, 2026, the Trust entered into a 10b5-1 plan (the "Plan") in accordance with Rule 10b5-1 promulgated under the Exchange Act pursuant to which Goldman Sachs & Co. LLC (the "Broker") has been appointed to sell up to 5,000,000 shares of Common Stock of the Company, subject to certain temporal, price and volume based parameters. The shares are not permitted to be sold under the Plan until the expiration of the required cooling off period set forth in Rule 10b5-1(c)(1)(ii)(B)(1) under the Securities Exchange Act of 1934, as amended, and the Plan will expire under its terms on July 8, 2026. The sales under the Plan, which represent just over 10% of Mr. Beck's direct and indirect beneficial ownership, are being made for continued diversification, estate planning purposes and to further support philanthropic pursuits. On March 30, 2026, Mr. Beck and the Company entered into a restricted stock unit ("RSU") cancellation agreement pursuant to which Mr. Beck voluntarily forfeited and cancelled all unvested RSUs held by Mr. Beck representing an aggregate of 392,155 shares of the Company's common stock. Mr. Beck's focus is the long-term appreciation of shareholder value rather than short-term cash or equity incentives. At Mr. Beck's request, the capital previously allocated for this compensation will be redirected toward Company priorities and strategic R&D initiatives, reinforcing a shared commitment to disciplined fiscal management and growth | ||
