Seagate Commences Exchange Offers and Consent Solicitations for Eight Series of Senior Notes

Seagate Technology Holdings plc ("Seagate") (NASDAQ:STX) today announced the commencement of offers to certain Eligible Holders (as defined below) to exchange (collectively, the "Exchange Offers" and each, an "Exchange Offer") any and all outstanding notes of the following eight series issued by Seagate HDD Cayman ("Seagate HDD") (the "Old Notes") for new notes to be issued by Seagate Data Storage Technology Ptd. Ltd ("SDST") (the "New Notes") as described in the table below, and related consent solicitations upon the terms and conditions set forth in the confidential Offering Memorandum and Consent Solicitation Statement dated May 28, 2025 (the "Offering Memorandum and Consent Solicitation Statement").

The following table below summarizes the principal economic terms of the Exchange Offers:

Upon the terms and subject to the conditions set forth in the Offering Memorandum and Consent Solicitation Statement, in exchange for each $1,000 principal amount of Old Notes validly tendered, and not validly withdrawn, prior to 5:00 p.m., New York City time, on June 10, 2025, unless extended (such date and time, as it may be extended, the "Early Participation Deadline"), Eligible Holders whose Old Notes are accepted for exchange will receive the total consideration set forth in the table above (the "Total Consideration"), which consists of $1,000 principal amount of New Notes and a cash amount of $1.25. The Total Consideration includes an early participation premium set forth in the table above (the "Early Participation Premium"), which consists of $50 principal amount of New Notes and $1.25 in cash. Eligible Holders whose Old Notes are validly tendered after the Early Participation Deadline and prior to the Expiration Time will only be eligible to receive the exchange consideration set forth in the table above (the "Exchange Consideration"), which is equal to $950 principal amount of New Notes.

The Exchange Offers commenced on May 28, 2025. The Exchange Offers will expire at 5:00 p.m., New York City time, on June 26, 2025, unless extended (such date and time, as it may be extended, the "Expiration Time"). Tenders of Old Notes may not be withdrawn after 5:00 p.m., New York City time, on June 10, 2025, unless extended (such date and time, as it may be extended, the "Withdrawal Deadline"), except in certain limited circumstances as set forth in the Offering Memorandum and Consent Solicitation Statement.

The Exchange Offers are subject to certain conditions described in the Offering Memorandum and Consent Solicitation Statement.

The principal difference between the Old Notes and the New Notes is the entities that will act as an issuer versus as a guarantor, as shown below:

Other than the identity of SDST as the issuer and as an obligor, the terms of the New Notes are identical to the Old Notes with respect to their interest rate, interest payment dates, optional redemption prices and maturity. The New Notes will be issued by SDST and guaranteed by the same guarantors as the Old Notes and SDST's recently issued its 5.875% Senior Notes due 2030 (the "2030 Notes") in addition to Seagate HDD (which is the issuer of the Old Notes). The New Notes will have substantially the same covenants as the Old Notes and the 2030 Notes and are subject to the same business and financial risks.

No accrued but unpaid interest will be paid on the Old Notes in connection with the Exchange Offers. However, interest on the applicable New Note will accrue from and including the most recent interest payment date of the tendered Old Note.

In conjunction with the Exchange Offer, SDST is soliciting consents (the "Consent Solicitations") to eliminate substantially all restrictive covenants and certain of the default provisions (the "Proposed Amendments") in the indenture governing the Old Notes. Holders who tender their Old Notes in the Exchange Offer will be deemed to have submitted consents pursuant to the Consent Solicitation. Each Consent Solicitation with respect to a series of Old Notes is to amend the indenture governing such series of Old Notes. The consummation of the Exchange Offer is not subject to, or conditioned upon, the receipt of the requisite consents or to any minimum amount of Old Notes being tendered for exchange. Eligible Holders may not deliver consents without tendering such series of Old Notes in the Exchange Offer.

Available Documents and Other Details

Documents relating to the Exchange Offers and the Consent Solicitations will only be distributed to holders of Old Notes who complete and return an eligibility form confirming that they are either a "qualified institutional buyer" as defined in Rule 144A or not a "U.S. person" as defined in Rule 902 in compliance with Regulation S under the Securities Act and, if in Singapore, a separate eligibility form confirming that they are an "accredited investor" as defined in Section 4A of the Securities and Futures Act 2001 of Singapore, as modified or amended from time to time (the "SFA"), or an "institutional investor" as defined in Section 4A of the SFA, in each case pursuant to and in accordance with the requirements of the SFA.
