THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 5:00 P.M. NEW YORK CITY TIME,
ON OCTOBER 15, 2025 UNLESS THE OFFER IS EXTENDED OR EARLIER TERMINATED (THE “EXPIRATION DATE”).

The Company will file a Solicitation/Recommendation Statement on Schedule 14D-9 (“Schedule 14D-9”) with the United States Securities and Exchange Commission (the “SEC”) and disseminate the Schedule 14D-9 to the Company’s securityholders. The Schedule 14D-9 will include important information, and should be read carefully and in its entirety before any decision is made with respect to the Offer.

Conditions to the Offer” in the Offer to Purchase; (iii) that none of the conditions described under “The Offer—Section 11.

Conditions to the Offer”.

Upon the terms and subject to the conditions of the Offer (including, if the Offer is extended or amended, the terms and conditions of such extension or amendment), Purchaser will accept for payment and pay for all Securities that are validly tendered and not properly withdrawn in accordance with “The Offer—Section 4. Withdrawal Rights” of the Offer to Purchase before 5:00 p.m., New York City time, on the Expiration Date.

In the event that Purchaser does not acquire all of the outstanding Securities, Purchaser may, at its election, in accordance with the applicable provisions of Rule 14d-11 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), provide for a subsequent offering period in which it would offer to purchase, at the same price of the Offer, any Securities that remain outstanding following the Expiration Date of the Offer.

You may withdraw Securities at any time prior to the Expiration Date and, if we have not accepted your Securities for payment by November 17, 2025 (which is the 60^th day after the date of the commencement of the Offer), you may withdraw them at any time after that date until we accept Securities for payment. If Purchaser provides for a subsequent offering period in accordance with Rule 14d-11 promulgated under the Exchange Act, you will have limited withdrawal rights with respect to any Securities you have tendered during such subsequent offering period. Securities tendered pursuant to the Offer during a subsequent offering period may be withdrawn at any time prior to 5:00 p.m. New York City time, on the date of the tender of such Securities. To withdraw Securities, you must deliver an executed written notice of withdrawal, or a facsimile of one, with the required information to the Tender Agent while you still have the right to withdraw the Securities. See “The Offer—Section 4. Withdrawal Rights” in the Offer to Purchase.

The Offer to Purchase, the related Letter of Transmittal and other related materials will be mailed to record holders of the Securities, and the Offer to Purchase and other related materials will also be furnished to brokers, dealers, commercial banks, trust companies and other securities intermediaries whose names appear on the Company’s shareholder list or, if applicable, who are listed as participants in a clearing agency’s security position listing for subsequent transmittal to beneficial owners of the Securities. Brokers, dealers, banks and trust companies will be reimbursed by Purchaser for customary mailing and handling expenses incurred by them in forwarding the Offer materials to their customers. We will also mail Offer to Purchase, the related Letter of Transmittal and/or other related materials to any record or beneficial holder of Securities that requests a copy thereof.

All questions as to the validity, form, eligibility (including time of receipt) and acceptance for payment of any tender of Securities, including questions as to the proper completion of any Letter of Transmittal, or other required documents, will be determined by Purchaser in its sole and absolute discretion (which may be delegated to the Tender Agent), which determination will be final and binding on all parties.

Generally, if you are a U.S. Holder (as defined in the Offer to Purchase), the sale of your Securities pursuant to the Offer will be a taxable transaction for United States federal income tax purposes. See “The Offer—Section 5. Material U.S. Federal Income Tax Consequences” in the Offer to Purchase. Purchaser urges holders of Securities to consult their own tax advisors about the tax consequences of the Offer in light of their particular circumstances.
