Borr Drilling Limited - Completes Acquisition of Five Rigs Through New Joint Venture

Hamilton, Bermuda, July 29, 2026 - Borr Drilling Limited (NYSE and OSE: BORR)
("Borr Drilling" or the "Company") today announced that BC Ventures Limited ("BC
Ventures"), a 50/50 joint venture between the Company and its long-term well
construction partner in Mexico, has completed the previously announced
acquisition of five premium jack-up rigs from Fontis Finance Ltd. for a total
purchase price of $287 million.

Under the transaction, BC Ventures has acquired the rig-owning entities of two
Friede & Goldman JU-2000E design rigs (Oberon and Titania FE) and three
LeTourneau Super 116-C design rigs (Courageous, Defender, and Intrepid). These
five rigs are currently located in Mexico.

BC Ventures has financed the acquisition through (i) a $237 million non-recourse
seller's credit and (ii) a $25 million cash contribution from each of the
Company and its local partner. The seller's credit matures in January 2029 and
is secured by, among other things, a first priority lien on the five jack-up
rigs.

This strategic transaction increases the Company's owned and jointly-owned fleet
to 34 rigs and expands its presence in Mexico, a well-established shallow-water
market, while enhancing the Company's ability to capitalize on growing demand
for secure, reliable and diversified sources of energy, both in the region and
internationally.
