GENERAL INSTRUCTIONS & INFORMATION

1. Capitalized terms not defined in this Claim Form have the meanings ascribed to them in the Stipulation and Agreement of Settlement dated April 4, 2025 (“Stipulation”), and in the Notice that accompanies this Claim Form.

2. It is important that you completely read and understand the accompanying Notice. The Notice describes the proposed Settlement of the Action, 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. By signing and submitting this Claim Form, you will be certifying that you have read and understand the Notice, including the Releases described therein and provided for herein.

3. This Claim Form is directed to all members of the “Settlement Class” defined below. The Settlement Class consists of the following, regardless of which state or country the person or entity may reside or be domiciled in:

all persons and entities who purchased or otherwise acquired publicly traded Capstone Green Energy Corporation (“Capstone”) securities between November 11, 2020 and October 4, 2023, inclusive (the “Settlement Class Period”) and were allegedly damaged thereby.

4. “Capstone Securities” means publicly traded Capsone Securities. All persons and entities that are members of the Settlement Class are “Settlement Class Members.”

5. Excluded from the Settlement Class are Defendants, the officers and directors of Capstone, at all relevant times, members of their immediate families and their legal representatives, heirs, successors, or assigns, and any entity in which Defendants have or had a controlling interest. Also excluded are any persons or entities who properly exclude themselves by filing a valid and timely request for exclusion in accordance with the requirements set by the Court.

6. To be potentially eligible to recover from the Net Settlement Fund, you must complete and sign this Claim Form, and submit your Claim Form to the Claims Administrator as instructed below. If you fail to submit a properly completed and addressed Claim Form by the date specified below, your Claim may be rejected, and you may be precluded from receiving any recovery from the Net Settlement Fund created in connection with the Settlement of the Action.

7. Submission of this Claim Form, however, does not ensure that you will share in the Net Settlement Fund. 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.

8. YOU MUST MAIL OR SUBMIT YOUR COMPLETED AND SIGNED CLAIM FORM SO THAT IT IS POSTMARKED NO LATER THAN OCTOBER 23, 2025,TO THE FOLLOWING ADDRESS:

ALTERNATIVELY, YOU MAY OBTAIN, COMPLETE, AND SUBMIT AN ELECTRONIC CLAIM BY 11:59 P.M. ET ON OCTOBER 23, 2025 AT WWW.STRATEGICCLAIMS.NET/CAPSTONE.

9. To be considered timely, your Claim Form must be mailed by first-class mail and postmarked, or submitted electronically, by the deadline above. Unless your Claim Form is submitted with a postmark by first-class mail, it will be deemed to have been submitted when actually received by the Claims Administrator.

10. Use the Schedule of Transactions in Part II of this Claim Form to supply all required details of your transaction(s) (including free transfers and deliveries) in and holdings of Capstone Securities. On this schedule, please provide all of the requested information with respect to your holdings, purchases, acquisitions, and sales of Capstone Securities, regardless of whether such transactions resulted in a profit or a loss. Failure to report all transaction and holding information during the requested time period may result in the rejection of your Claim.

11. You must submit supporting documentation for the transactions reported in this Claim Form, such as broker confirmation slips, broker account statements, an authorized statement from your broker reporting information about your transactions, or other similar documents. The Parties and the Claims Administrator do not independently have information about your investments in Capstone Securities. If such documents are not in your possession, please obtain copies 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. Also, please do not highlight any portion of the Claim Form or any supporting documents.

12. Separate Claim Forms should be submitted for each separate legal entity (e.g., a Claim Form from joint owners should not include the transactions of just one of the joint owners, and an individual should not combine his or her IRA transactions with transactions made solely in the individual’s name). Conversely, a single Claim Form should be submitted on behalf of one legal entity that includes all transactions made by that entity, no matter how many separate accounts that entity has (e.g., a corporation with multiple brokerage accounts should include all transactions made in all accounts on one Claim Form).

13. All joint beneficial owners must each sign this Claim Form, and their names must appear in Part I of this Claim Form. If you purchased or otherwise acquired Capstone Securities during the Settlement Class Period and held the Capstone Securities in your name, you are the beneficial owner as well as the record owner and you must sign this Claim Form to participate in the Settlement. If you purchased or otherwise acquired Capstone Securities during the Settlement Class Period for your own benefit, but the Capstone Securities were registered in the name of a third party, such as a nominee or brokerage firm, you are still 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 to be eligible to participate in the Settlement.

14. Agents, executors, administrators, guardians, and trustees must complete and sign the Claim Form on behalf of persons and entities represented by them, and they must:

a. expressly state the capacity in which they are acting;

b. identify the name, account number, 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 Capstone Securities; and

c. furnish 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 brokers demonstrating only that they have discretionary authority to trade securities in another person/entity’s accounts.)

15. By submitting this Claim Form, you will be making a request to share in the proceeds of the Settlement described in the Notice. If you are NOT a Settlement Class Member, or are excluded from the definition of the Settlement Class, or if you, or someone acting on your behalf, submitted a request for exclusion from the Settlement Class in accordance with the instructions set forth in the Notice, 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.

16. If you are a Settlement Class Member and you do not request exclusion from the Settlement Class pursuant to the instructions set forth in the Notice, you will be bound by the terms of the Settlement and any orders or judgments entered in this Action, WHETHER OR NOT YOU SUBMIT A CLAIM FORM OR RECEIVE A PAYMENT.

17. NOTICE REGARDING INSTITUTIONAL FILERS: Representatives with authority to file on behalf of (a) accounts of multiple Settlement Class Members and/or (b) institutional accounts with large numbers of transactions (“Representative Filers”) must submit information regarding their transactions in an electronic spreadsheet format. If you are a Representative Filer, you must contact the Claims Administrator at efile@strategicclaims.net or visit their website at www.strategicclaims.net/capstone to obtain the required file layout. Claims which are not submitted in electronic spreadsheet format and in accordance with the Claims Administrator’s instructions may be subject to rejection. All Representative Filers MUST also submit a manually signed Claim Form, as well as proof of authority to file (see Item 14 of the General Instructions), along with the electronic spreadsheet format. No claims submitted in electronic spreadsheet format will be considered to have been properly submitted unless the Claims Administrator issues to the Claimant a written acknowledgment of receipt and acceptance of electronically submitted data.

18. NOTICE REGARDING ONLINE FILING: Claimants who are not Representative Filers may submit their claims online using the electronic version of the Claim Form hosted at www.strategicclaims.net/capstone. If you are not acting as a Representative Filer, you do not need to contact the Claims Administrator prior to filing; you will receive an automated e-mail confirming receipt once your Claim Form has been submitted. If you are unsure if you should submit your claim as a Representative Filer, please contact the Claims Administrator at info@strategicclaims.net or (866) 274-4004. If you are not a Representative Filer, but your claim contains a large number of transactions, the Claims Administrator may request that you also submit an electronic spreadsheet showing your transactions to accompany your Claim Form.

19. PLEASE NOTE: YOUR CLAIM IS NOT DEEMED SUBMITTED UNTIL YOU RECEIVE AN ACKNOWLEDGEMENT POSTCARD OR CONFIRMATION EMAIL. THE CLAIMS ADMINISTRATOR WILL ACKNOWLEDGE RECEIPT OF YOUR CLAIM FORM BY MAIL OR EMAIL WITHIN 60 DAYS. IF YOU DO NOT RECEIVE AN ACKNOWLEDGEMENT POSTCARD OR CONFIRMATION EMAIL WITHIN 60 DAYS, PLEASE CONTACT THE CLAIMS ADMINISTRATOR.
