Cadeler details 1:1 UK redomiciliation offer

Cadeler is being redomiciled to the UK via a 1-for-1 share exchange into Cadeler plc, backed by a EUR 220 million bridge facility to fund a post-offer squeeze-out.

Rhea-AI Filing Summary

Cadeler A/S (CDLR) is the subject of an exchange offer through Cadeler plc (“NewCo”) to effect a redomiciliation from Denmark to the United Kingdom. For each outstanding Cadeler share (including shares underlying ADSs) validly tendered and not withdrawn, holders are offered one NewCo ordinary share.

As of September 18, 2026, Cadeler had 386,053,341 ordinary shares issued, including 169,267 treasury shares. NewCo has arranged a EUR 220 million bridge facility with DNB Bank ASA to finance a post-offer cash squeeze-out of remaining Cadeler shares, secured by a first-priority pledge over NewCo’s Cadeler shares and restricting dividends while outstanding.

Executive management and key employees received 1,574,042 RSUs related to 2026 performance, potentially equal to about 0.41% of NewCo’s share capital, and an earlier 193,011 RSU grant related to 2024 performance was accelerated to vest on September 21, 2026. Cadeler reported USD 8.14 million in significant 2024 transactions with BW Group entities.

Key Terms

5 terms

Redomiciliation regulatory

"The purpose of the Offer is to effect the redomiciliation of Cadeler"

Redomiciliation is when a company legally changes its country of incorporation while keeping the same business and assets, like moving a house to a new neighborhood but keeping the same furniture. Investors care because the company then follows a different set of laws and tax rules, which can change shareholder rights, reporting standards, dividend treatment and the ease of trading the stock, potentially affecting risk and return.

Squeeze-out regulatory

"completion of a compulsory acquisition ... for cash (which is referred to as the “Squeeze-out”)"

A squeeze-out is a legal process where an owner or group that controls a company forces remaining minority shareholders to sell their shares, typically after gaining a large enough stake. It matters to investors because it ends minority ownership and determines the price and timing of exit—potentially providing a quick cash payout or locking in a lower-than-expected sale price—so shareholders should evaluate whether the offered terms fairly reflect the company's value.

bridge facility agreement financial

"entered into a bridge facility agreement for a loan of up to EUR 220 million"

A bridge facility agreement is a short-term loan contract that provides immediate cash to a company while it arranges longer-term financing or completes a sale. It matters to investors because it affects a company’s near-term liquidity, debt load and the timing or terms of permanent funding; like a temporary bridge that keeps traffic moving while a permanent span is built, it fills funding gaps and can change a company’s financial picture.

restricted stock units financial

"executive management and certain key employees were granted a total of 1,574,042 restricted stock units"

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

change of control restriction regulatory

"includes customary covenants, including a change of control restriction substantially identical"

(b)

On August 26, 2026, the Group’s executive management and certain key employees were granted a total of 1,574,042 restricted stock units (“RSUs”) related to the financial year ended December 31, 2026. Each RSU allows the participant to receive one share upon vesting. The RSUs will vest on August 26, 2030 and expire on December 26, 2030. Vesting of the RSUs is conditional on continued employment within the Group, save where the participant’s employment terminates in circumstances entitling him to good leaver treatment under his RSU program. The total number of potential shares that could be delivered pursuant to the RSUs issued under this programme is 1,574,042, corresponding to approximately 0.41% of NewCo’s share capital assuming all Cadeler Shareholders participate in and are accepted in the Offer. In connection with the grant of RSUs in 2026, the Cadeler Board decided to use the authorization set out in Cadeler’s remuneration policy to deviate from the threshold set out therein and exceed the annual value of share-based incentive grants for the purposes of retention and incentivization.

​

In May 2024, the Group’s executive management were granted a total of 193,011 RSUs, without consideration related to the financial year ended December 31, 2024. These RSUs were originally due to vest in May 2027, however, in connection with the Offer, the Cadeler Board approved the accelerated vesting of such RSUs, such that the RSUs vested on September 21, 2026. Each RSU allows the participant to receive one share upon vesting. The total number of Cadeler Shares that will be delivered pursuant to such RSUs is 193,011, corresponding to approximately 0.05% of the NewCo’s share capital assuming all Cadeler Shareholders participate in and are accepted in the Offer. The RSUs are expected to settle on or around September 22, 2026 on an 85% shares / 15% cash basis, whereby Mikkel Gleerup, Chief Executive Officer, will receive 104,401 shares while Peter Brogaard Hansen, Chief Financial Officer, will receive 59,658 shares from Cadeler’s treasury shares and with the remainder of the RSUs to be settled in cash. No RSUs will be outstanding under this program after settlement.

Except as set forth above, no transactions in Cadeler Shares have been effected during the past 60 days by Cadeler, or, to Cadeler’s knowledge, after making reasonable inquiry, by any of Cadeler’s directors, executive officers or affiliates.

Item 9.   Persons/Assets Retained, Employed, Compensated or Used.

(a) Except as set forth in this Schedule TO or as incorporated herein by reference, and except that such solicitations or recommendations may be made by NewCo’s directors, officers or employees, for which services no additional compensation will be paid, neither NewCo nor any person acting on its behalf has employed, retained or compensated any person to make solicitations or recommendations to Cadeler Shareholders on NewCo’s behalf concerning the Offer or the Redomiciliation. The information set forth in the sections of the Prospectus/Offer to Exchange entitled “The Offer and the Redomiciliation —  Procedures for Tendering Cadeler Shares and Cadeler ADSs,” “The Offer and the Redomiciliation —  Independent Expert Statement,” “The Offer and the Redomiciliation — Fees and Commissions,” and “The Offer and the Redomiciliation — Fees and Expenses” is incorporated into this Schedule TO by reference.
