| Item 3. | Source and Amount of Funds or Other Consideration | |
All of the Shares beneficially owned by the Reporting Persons were acquired as part of the redomiciliation of Cadeler A/S (the "Predecessor Issuer") from Denmark to the United Kingdom (the "Redomiciliation"), which was effected by way of a registered exchange offer (the "Exchange Offer") whereby Scorpio Holdings and SSH received 41,385,792 Shares and 7,971,033 Shares, respectively, in a one-for-one exchange for the same number of ordinary shares, nominal value DKK 1.00 per share, of the Predecessor Issuer (the "Predecessor Shares") held by them prior to the Redomiciliation. No other consideration was paid by the Reporting Persons in connection with the foregoing. | ||
| Item 4. | Purpose of Transaction | |
The Reporting Persons acquired all of the Shares to which this Schedule 13D relates in the Exchange Offer, which was completed in connection with the Redomiciliation.
The Issuer launched the Exchange Offer on September 21, 2026. Scorpio Holdings and SSH tendered all of their 41,385,792 and 7,971,033 Predecessor Shares, respectively, in the Exchange Offer. The Exchange Offer expired on October 28, 2026, and the Issuer announced the final results of the Exchange Offer on November 2, 2026. Upon that announcement, the tender of Predecessor Shares by Scorpio Holdings and SSH, and their corresponding commitment to acquire the Shares, became irrevocable. As a result, as of November 4, 2026, the Reporting Persons ceased to beneficially own any Predecessor Shares and acquired 49,356,825 Shares in exchange, representing approximately 13.89% of the outstanding Shares.
The Reporting Persons first became holders of Predecessor Shares in connection with the Predecessor Issuer's business combination with Eneti Inc., which was completed in December 2023, and thereafter increased their position through private placements by the Predecessor Issuer completed in February 2024 and March 2026. The funds used to acquire the Predecessor Shares that were exchanged in the Exchange Offer came from the working capital of Scorpio Holdings and SSH. | ||

| (a) | Scorpio Holdings and Ms. Lolli-Ghetti may be deemed to beneficially own 49,356,825 Shares, representing approximately 13.89% of the outstanding Shares, consisting of 41,385,792 Shares held directly by Scorpio Holdings and 7,971,033 Shares held by SSH. SSH may be deemed to beneficially own 7,971,033 Shares, representing approximately 2.24% of the outstanding Shares. The foregoing beneficial ownership percentages are based on a total of 355,404,838 Shares outstanding, according to information provided by the Issuer. | |
| (b) | Scorpio Holdings and Ms. Lolli-Ghetti have the shared power to vote or direct the vote, and to dispose or direct the disposition, of 49,356,825 Shares.
