Amendments to Existing Restricted Stock Units and Performance Stock Units

On May 7, 2025, the Board of Directors of the Company (the “Board”) approved amendments to outstanding restricted stock unit (“RSU”) agreements (the “RSU Amendments”) and performance-based restricted stock unit (“PSU”) agreements (“PSU Amendments”) under the Ziff Davis, Inc. 2024 Equity Incentive Plan (the “2024 Plan”) and the 2015 Ziff Davis, Inc. Stock Option Plan (“2015 Plan”). The RSU Amendments and PSU Amendments provide that for every dividend paid with respect to the shares of the Company’s common stock (“Shares”) underlying a holder’s existing RSUs or PSUs, as applicable, such RSUs or PSUs will accrue dividend equivalents (“Dividend Equivalent Rights”), subject to the vesting, settlement, clawback, and other conditions applicable to the Shares underlying the RSUs or PSUs, as applicable. Dividend Equivalent Rights represent the right to receive a cash amount equal to the value of all cash dividends declared and paid in respect of one Share underlying one RSU or PSU, as applicable, commencing on the grant date of the applicable RSU or PSU and ending on the date that such RSU or PSU is settled pursuant to the RSU or PSU agreement.

The Company does not have any current plan or intention to declare dividends in the foreseeable future.

The Company is communicating the RSU Amendments and PSU Amendments to existing RSU and PSU holders through the form of notice (the “Notice”). The foregoing description of the Notice does not purport to be complete and is qualified in its entirety by reference to the Notice, which is filed herewith as Exhibit 10.1 to this Form 10-Q and incorporated herein by reference.
