On April 8, 2026, the Company announced that the board of directors of the Company appointed Joshua Warren as its CFO. Mr. Warren will commence employment with the Company on April 13, 2026 (the “Start Date”).

Mr. Warren, age 46, has served as the Chief Financial Officer of Envestnet, Inc. from 2023 to 2025. Previously, he served as the Managing Director and Global Head of Business Strategy for iShares and Index Investments for BlackRock, Inc. (“BlackRock”) from 2021 to 2023, and prior to that, he was the Managing Director in BlackRock’s Corporate Strategy and Development team. Prior to joining BlackRock in 2015, Mr. Warren’s experience included roles at Barclays Capital Inc.; Foros Group; the United States Department of the Treasury; and Skadden, Arps, Slate, Meagher & Flom LLP. Mr. Warren holds a Juris Doctor from the New York University School of Law and a Bachelor of Arts in Philosophy and History from Dartmouth College.

In connection with his appointment, Mr. Warren and the Company entered into an employment agreement, dated April 2, 2026 (the “Employment Agreement”). Pursuant to the Employment Agreement, Mr. Warren will be paid an annual base salary of $500,000, and he will be eligible to receive an annual target cash bonus equal to 110% of his base salary, with any annual cash bonus for fiscal year 2026 pro-rated from the Start Date. Beginning with fiscal year 2027, Mr. Warren will be eligible to receive an annual equity award with a target grant date value of $2,250,000. As soon as administratively practicable after the Start Date, Mr. Warren will receive a one-time, new-hire equity grant with a grant date value of $1,500,000 (the “New Hire Award”), of which (i) $750,000 will be granted as non-qualified stock options, (ii) $500,000 will be granted as restricted stock units (“RSUs”), and (iii) $250,000 in cash. The portion of the New Hire Award that consists of stock options and RSUs will vest 50% on each of the third and fourth anniversaries of the grant date, subject to continued service. The portion of the New Hire Award that consists of cash will be paid within 30 days of the Start Date, and will be repayable in full by Mr. Warren on a gross basis if he resigns or if his employment is terminated by the Company for Cause (as defined in the Executive Severance Plan), in each case, prior to the first anniversary of the Start Date.

The Employment Agreement provides that Mr. Warren will be entitled to participate in the Company’s Executive Severance Plan and, promptly after the Start Date, will receive and become a party to an equity letter agreement substantially in the form attached as Exhibit 10.8 to the Company’s Annual Report on Form 10-K for the year ending August 31, 2025.

The foregoing summary of the Employment Agreement does not purport to be complete and is subject to, and qualified in its entirety by reference to the full text of the Employment Agreement, a copy of which will be filed with the Company’s Quarterly Report on Form 10-Q for the quarter ending May 31, 2026, and the terms of which are incorporated herein by reference.
