#### Exhibit 99.1

#### Borr Drilling Limited - Completes Offering of Convertible Senior Notes due 2033

**Hamilton, Bermuda, April 17, 2026** – Borr Drilling Limited (NYSE and Euronext Growth Oslo: BORR) ("Borr Drilling" or the "Company") today announced that is has completed its previously announced offering of convertible senior notes due 2033 (the "Notes"). The Company sold $300 million aggregate principal amount of the Notes, including $40 million aggregate principal amount of the Notes sold pursuant to the initial purchasers' exercise in full of their option to purchase additional Notes to cover over-allotments in connection with the offering.

The Notes are senior, unsecured obligations of the Company and mature on May 1, 2033. They bear interest at a rate of 3.50% per annum, which is payable semi-annually, beginning on November 1, 2026. The Notes are convertible into the Company's common shares, cash, or a combination of shares and cash, at the Company's election. The conversion rate for the Notes will initially equal 125.0000 common shares per $1,000 principal amount of the Notes, which is equivalent to an initial conversion price of approximately $8.00 per common share. Such initial conversion price represents a conversion premium of over 40% with reference to the closing price of the Company's common shares of $5.70 on the New York Stock Exchange on April 14, 2026. The conversion rate is subject to adjustment upon the occurrence of certain events.

The Company intends to use the proceeds from the sale of the Notes to repurchase its existing convertible bonds due 2028 (the "2028 Convertible Bonds") and for general corporate purposes.

In connection with the offering, the Company has agreed with certain holders of the 2028 Convertible Bonds to repurchase $195.2 million aggregate principal amount of the 2028 Convertible Bonds.
