Luxembourg - 14 March 2023 - Subsea 7 S.A. ("Subsea7") (Oslo Børs: SUBC, ADR:

SUBCY) today announced that it has completed the acquisition of 187,889,551

shares in Seaway 7 ASA ("Seaway7"), corresponding to 21.52% of Seaway7's issued

and outstanding share capital, from Songa Capital AS, Lotus Marine AS and West

Coast Invest AS. Following completion of the acquisition Subsea7 holds 93.94% of

the issued and outstanding share capital of Seaway7.

As consideration, Songa Capital AS, Lotus Marine AS and West Coast Invest AS

have received 1 new Subsea7 share for every 22 Seaway7 shares, in total

8,540,433 new shares (the "Consideration Shares") corresponding to approximately

2.90% of the current issued share capital of Subsea7.

The Consideration Shares have the same rights as the existing Subsea7 shares but

are not eligible for the proposed NOK 4.00 per share dividend tabled for

approval at the forthcoming annual general meeting of Subsea7 on 18 April 2023

(the "Annual Dividend"). The Consideration Shares have thus been issued on a

separate ISIN and will not be listed and tradable on the Oslo Stock Exchange

until the Consideration Shares have been transferred to the ordinary ISIN of the

Subsea7 shares following the record date for the Annual Dividend, scheduled for

21 April 2023.

Following the issuance of the Consideration Shares, Subsea7 has an issued share

capital of USD 605,716,932 represented by 302,858,466 shares, each with a

nominal value of USD 2.00.

As announced on 13 March 2023 Subsea7 has launched a voluntary offer (the

"Offer") for the remaining outstanding shares in Seaway7. For further details of

the Offer, see the stock exchange release published on Seaway7's ticker (SEAW7)

on 13 March 2023.
