Hamilton, Bermuda, June 9, 2026 - Borr Drilling Limited (NYSE and OSE: BORR) ("Borr Drilling" or the "Company") today announced the pricing terms of its previously announced offer by Borr IHC Limited, its wholly-owned subsidiary (the "Issuer"), to purchase for cash (the "Tender Offer") (i) any and all of its outstanding 10.000% Senior Secured Notes due 2028 (the "2028 Notes") and (ii) any and all of its outstanding 10.375% Senior Secured Notes Due 2030 (together with the 2028 Notes, the "Notes"), and the related solicitation of consents (the "Consent Solicitation"), in each case pursuant to the terms and subject to the conditions set forth in the offer to purchase and consent solicitation statement dated May 26, 2026 (as amended or supplemented from time to time, the "Statement"). Capitalized terms used in this release but not otherwise defined have the meaning given in the Statement. 

The table below indicates, among other things, the Total Consideration for each $1,000 original principal amount of the 2028 Notes validly tendered at or prior to 5:00 p.m., New York City time, on June 8, 2026, as calculated at 10:00 a.m. (New York City time) today, June 9, 2026 (the "Price Determination Date") in accordance with the terms of the Statement:

1. As of May 22, 2026. This reflects an aggregate original principal amount of 2028 Notes adjusted to reflect amortization in respect thereof.
2. The factor is a number that represents a fraction (expressed as a decimal rounded to 8 decimal digits) the numerator of which represents the unpaid principal amount of such series of securities and the denominator which represents the initial principal amount outstanding of such series of securities (the "Factor"). The Total Consideration will be the amount set forth in the table above multiplied by the applicable Factor, which reflects the partial amortization of the 2028 Notes.
3. For each $1,000 original principal amount of 2028 Notes validly tendered and accepted for purchase and with respect to which the applicable Holder has provided its Consent. The Early Tender Payment includes a Consent Payment of $2.50 for each $1,000 original principal amount of 2028 Notes. Holders that validly tender their 2028 Notes and thereby deliver their Consents at or prior to the Early Tender/Consent Deadline (and do not validly withdraw such 2028 Notes and therefore do not validly revoke the related Consents) will be eligible to receive the Consent Payment of $2.50 per $1,000 original principal amount of 2028 Notes in respect of such 2028 Notes.
4. Excludes Accrued Interest, which will be paid in addition to the Total Consideration.
5. The Total Consideration for the 2028 Notes validly tendered has been determined in the manner described in the Statement by reference to the fixed spread (the "Fixed Spread") specified above plus the yield (the "Reference Yield") based on the bid-side price of the U.S. Treasury Reference Security specified above (the "Reference Security") as quoted on the Bloomberg Bond Trader FIT3 series of pages (the "Reference Page") as of the Price Determination Date, which includes the Early Tender Payment (including the Consent Payment).

Holders may continue to tender their Notes (and thereby deliver Consents) until 5:00 p.m., New York City time, on June 24, 2026, in respect of the Tender Offer and Consent Solicitation, unless extended or earlier terminated by the Issuer in its sole discretion, subject to applicable law (the "Expiration Time").

The Issuer reserves the right in its sole discretion, subject to applicable law, to (i) waive prior to the Expiration Time any and all conditions to the Tender Offer; (ii) extend the Expiration Time; (iii) amend the terms of the Tender Offer and Consent Solicitation in any respect; or (iv) terminate, withdraw or otherwise decide not to proceed with the Tender Offer and Consent Solicitation at any time prior to or at the Expiration Time and not accept for purchase or payment any Notes not theretofore accepted for purchase or payment.
