THIS NOTICE WAS AUTHORIZED BY THE COURT. IT IS NOT A LAWYER SOLICITATION. PLEASE READ THIS NOTICE CAREFULLY AND IN ITS ENTIRETY.

YOU ARE HEREBY NOTIFIED that a hearing will be held on September 19, 2024, at 2:00 p.m., before the Honorable William G. Young at the United States District Court, District of Massachusetts, John Joseph Moakley U.S. Courthouse, 1 Courthouse Way, Boston, MA 02210, to determine whether: (1) the proposed settlement (the “Settlement”) of the above-captioned Litigation as set forth in the Stipulation of Settlement (“Stipulation”) for $35 million in cash should be approved by the Court as fair, reasonable, and adequate; (2) the Judgment as provided under the Stipulation should be entered dismissing the Litigation with prejudice; (3) to award Lead Plaintiffs’ Counsel attorneys’ fees and expenses out of the Settlement Fund (as defined in the Notice of Pendency and Proposed Settlement of Class Action (“Notice”), which is discussed below) and, if so, in what amounts; (4) to pay Lead Plaintiffs for their costs and expenses in representing the Settlement Class out of the Settlement Fund and, if so, in what amount; and (5) the Plan of Allocation should be approved by the Court as fair, reasonable, and adequate.

There exists the possibility that the Court may decide to change the date and/or time of the Settlement Hearing, conduct the Settlement Hearing by video or telephonic conference, or otherwise allow Settlement Class Members to appear at the hearing by phone or videoconference, without further written notice to the Settlement Class. In order to determine whether the date and time of the Settlement Hearing have changed, or whether Settlement Class Members must or may participate by phone or video, it is important that you monitor the Court’s docket and the Settlement website, www.PegasystemsSecuritiesSettlement.com, before making any plans to attend the Settlement Hearing. Any updates regarding the Settlement Hearing, including any changes to the date or time of the hearing or updates regarding in-person or telephonic appearances at the hearing, will also be posted to that website. Also, if the Court requires or allows Settlement Class Members to participate in the Settlement Hearing by telephone or videoconference, the access information will be posted to the Settlement website, www.PegasystemsSecuritiesSettlement.com.

IF YOU PURCHASED OR OTHERWISE ACQUIRED PEGA COMMON STOCK BETWEEN JUNE 16, 2020 AND MAY 9, 2022, INCLUSIVE, AND EXPERIENCED LOSS, YOUR RIGHTS MAY BE AFFECTED BY THE SETTLEMENT OF THIS LITIGATION.

To share in the distribution of the Net Settlement Fund, you must establish your rights by submitting a Proof of Claim and Release form (“Proof of Claim”) by mail (postmarked no later than October 7, 2024) or electronically (no later than October 7, 2024). Your failure to submit your Proof of Claim by October 7, 2024 will subject your claim to rejection and preclude you from receiving any of the recovery in connection with the Settlement of this Litigation. If you purchased or otherwise acquired Pega common stock during the period between June 16, 2020 and May 9, 2022, inclusive, and do not request exclusion from the Settlement Class, you will be bound by the Settlement and any judgment and release entered in the Litigation, including, but not limited to, the Judgment, whether or not you submit a Proof of Claim.
