GENERAL INSTRUCTIONS To be eligible to receive a share of the Net Settlement Fund in connection with the Settlement of this Action, you must complete and sign this Proof of Claim and Release Form (“Claim Form”) and mail it by First-Class Mail to the address below, or submit it online by clicking Next below and following all the instructions, with supporting documentation, postmarked (if mailed) or submitted online no later than October 19, 2026. Mail to: Seagate Securities Litigationc/o Strategic Claims Services P.O. Box 230 600 N. Jackson St., Ste. 205 Media, PA 19063 Failure to submit your Claim Form by the date specified will subject your claim to rejection and may preclude you from being eligible to receive any money in connection with the Settlement. Do not mail or deliver your Claim Form to the Court, the Parties to the Action, or their counsel. Submit your Claim Form only to the Claims Administrator at the address set forth above or online by clicking Next below. It is important that you completely read and understand the Notice of (I) Pendency of Class Action and Proposed Settlement; (II) Settlement Fairness Hearing; and (III) Motion for Attorneys’ Fees and Litigation Expenses (“Notice”), including the proposed Plan of Allocation set forth in the Notice (“Plan of Allocation”). The Notice describes the proposed Settlement, how Settlement Class Members are affected by the Settlement, and the manner in which the Net Settlement Fund will be distributed if the Settlement and Plan of Allocation are approved by the Court. The Notice also contains the definitions of many of the defined terms (which are indicated by initial capital letters) used in this Claim Form. By signing and submitting this Claim Form, you will be certifying that you have read and that you understand the Notice, including the terms of the Releases described therein and provided for herein. This Claim Form is directed to all persons and entities who purchased or otherwise acquired common stock ofSeagate Technology Holdings plc (“Seagate”) from September 14, 2020 through April 19, 2023, inclusive (“Class Period”), and were allegedly damaged thereby (“Settlement Class”). Certain persons and entities are excluded from the Settlement Class by definition as set forth on page 8 of the Notice. By submitting this Claim Form, you are making a request to share in the proceeds of the Settlement described in the Notice. If you are not a Settlement Class Member (see the definition of the Settlement Class on page 8 of the Notice), or if you, or someone acting on your behalf, submitted a request for exclusion from the Settlement Class, do not submit a Claim Form. You may not, directly or indirectly, participate in the Settlement if you are not a Settlement Class Member. Thus, if you are excluded from the Settlement Class, any Claim Form that you submit, or that may be submitted on your behalf, will not be accepted. Submission of this Claim Form does not guarantee that you will share in the proceeds of the Settlement. The distribution of the Net Settlement Fund will be governed by the Plan of Allocation set forth in the Notice, if it is approved by the Court, or by such other plan of allocation as the Court approves. Use the Schedule of Transactions of this Claim Form to supply all required details of your transaction(s) (including free transfers and deliveries) in and holdings of Seagate common stock. In this Schedule, please provide all of the requested information with respect to your holdings, purchases, acquisitions, and sales of Seagate common stock, whether such transactions resulted in a profit or a loss. Failure to report all transaction and holding information during the requested time periods may result in the rejection of your claim. Please note: Only Seagate common stock purchased or acquired during the Class Period (i.e., the period from September 14, 2020 through April 19, 2023, inclusive) is eligible under the Settlement. However, because the PSLRA provides for a “90-day look-back period” (described in the Plan of Allocation set forth in the Notice), you must provide documentation related to your purchases, acquisitions, and sales of Seagate common stock during the period from April 20, 2023 through July 18, 2023 (i.e., the 90-day look-back period) in order for the Claims Administrator to calculate your Recognized Loss Amount under the Plan of Allocation and process your claim. Failure to report all transaction and holding information during the requested time periods may result in the rejection of your claim. You are required to submit genuine and sufficient documentation for all of your transactions in and holdings of the Seagate common stock set forth in the Schedule of Transactions of this Claim Form. Documentation may consist of copies of trade confirmations or account statements, or an authorized statement from your broker or other financial institution containing the transactional and holding information found in a trade confirmation or account statement. The Parties and the Claims Administrator do not independently have information about your investments in Seagate common stock. IF SUCH DOCUMENTS ARE NOT IN YOUR POSSESSION, PLEASE OBTAIN COPIES OF THE DOCUMENTS OR EQUIVALENT DOCUMENTS FROM YOUR BROKER. FAILURE TO SUPPLY THIS DOCUMENTATION MAY RESULT IN THE REJECTION OF YOUR CLAIM. DO NOT SEND ORIGINAL DOCUMENTS. Please keep a copy of all documents that you send to the Claims Administrator. One Claim Form should be submitted for each separate legal entity or separately managed account.Separate Claim Forms should be submitted for each separate legal entity (e.g., an individual should not combine his or her IRA transactions with transactions made solely in the individual’s name). Generally, a single Claim Form should be submitted on behalf of one legal entity including all holdings and transactions made by that entity on one Claim Form. However, if a single person or legal entity had multiple accounts that were separately managed, separate Claims may be submitted for each such account. The Claims Administrator reserves the right to request information on all the holdings and transactions in Seagate common stock made on behalf of a single beneficial owner. All joint beneficial owners must sign this Claim Form and their names must appear as “Claimants” in this Claim Form. The complete name(s) of the beneficial owner(s) must be entered. If you purchased or acquired Seagate common stock during the Class Period and held the shares in your name, you are the beneficial owner as well as the record owner. If you purchased or acquired Seagate common stock during the Class Period and the shares were registered in the name of a third party, such as a nominee or brokerage firm, you are the beneficial owner of these shares, but the third party is the record owner. The beneficial owner, not the record owner, must sign this Claim Form. Agents, executors, administrators, guardians, and trustees must complete and sign the Claim Form on behalf of persons represented by them, and they must: (a) expressly state the capacity in which they are acting; (b) identify the name, account number, last four digits of the Social Security Number (or Taxpayer Identification Number), address, and telephone number of the beneficial owner of (or other person or entity on whose behalf they are acting with respect to) the Seagate common stock; and (c) furnish herewith evidence of their authority to bind to the Claim Form the person or entity on whose behalf they are acting. (Authority to complete and sign a Claim Form cannot be established by stockbrokers demonstrating only that they have discretionary authority to trade securities in another person’s accounts.) By submitting a signed Claim Form, you will be swearing to the truth of the statements contained therein and the genuineness of the documents attached thereto, subject to penalties of perjury under the laws of the United States of America. The making of false statements, or the submission of forged or fraudulent documentation, will result in the rejection of your claim and may subject you to civil liability or criminal prosecution. If the Court approves the Settlement, payments to eligible Authorized Claimants pursuant to the Plan of Allocation (or such other plan of allocation as the Court approves) will be made after any appeals are resolved, and after the completion of all claims processing. The claims process will take substantial time to complete fully and fairly. Please be patient. PLEASE NOTE: As set forth in the Plan of Allocation, each Authorized Claimant shall receive their pro rata share of the Net Settlement Fund. If the prorated payment to any Authorized Claimant calculates to less than $10.00, it will not be included in the calculation and no distribution will be made to that Authorized Claimant.
