Exhibit 99.1

PRESS RELEASE

NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION IN ANY JURISDICTION WHERE ITS PUBLICATION WOULD BE UNLAWFUL

REOPENING OF THE MANDATORY PUBLIC TAKEOVER BID ON CMB.TECH

Communication in accordance with article 8, §1 of the Royal Decree of 27 April 2007 on public takeover bids.

Antwerp, October 9, 2024, 7h30 a.m. – CMB NV (“CMB”) announced that, pursuant to an order of the Belgian Financial Services and Markets Authority (the “FSMA”) of October 7, 2024, it will (i) make a subsequent additional payment of USD 0.52 (or EUR 0.47) per share to all shareholders who have transferred their shares to CMB in its mandatory public takeover bid for the shares in CMB.TECH NV¹ (“CMB.TECH” and the “Bid”) that expired on March 15, 2024 and (ii) reopen the Bid at an adjusted price of USD 12.66 per share.

FSMA order

On October 7, 2024, the FSMA ordered CMB, in light of the Market Court ruling of September 6, 2024, to increase the bid price by USD 0.52 per share and, more specifically, to:

Subsequent Payment

In accordance with the order of the FSMA, the Subsequent Payment per share will take place on October 31, 2024 and will be made to all (former) shareholders who have validly tendered their shares in the Bid and the concurrent U.S. tender offer during the acceptance period that expired on March 15, 2024. No additional actions are required from such (former) shareholders.

(Former) shareholders that tendered their shares in the U.S. tender offer will receive an additional payment of USD 0.52 per share. (Former) shareholders that tendered their shares in the Belgian offer will receive EUR 0.47 per share, i.e. the equivalent amount of the price increase in euros calculated using the WM/Reuters spot exchange rate for euros per U.S. dollar at 5:00 p.m. CET on the date of the order of the FSMA.

The Subsequent Payment will be made without any conditions or restrictions. If and to the extent that the Subsequent Payment cannot be executed (for reasons beyond the control of CMB), CMB will take necessary actions to ensure that funds are consigned to the Deposit and Consignment Fund (“Deposito- en Consignatiekas”) as per the order of the FSMA.

Reopening of the Bid and concurrent U.S. tender offer

In accordance with the order of the FSMA, CMB will reopen its Bid, which was made on the basis of a prospectus dated 13 February 2024 (the “Prospectus”) and in accordance with the Belgian Law of 1 April 2007 on public takeover bids and the Belgian Royal Decree of 27 April 2007 on public takeover bids.

The price of the Reopening will be USD 12.66 per share, reduced on a dollar-for-dollar basis by the gross amount per share of any future distributions by CMB.TECH to its shareholders with a payment date prior to the settlement date of the Reopening. This bid price takes into account the initial reference price of the Bid of USD 18.43, which is increased by USD 0.52 in accordance with the order by the FSMA and decreased by USD 6.29, the aggregate amount of distributions made by CMB.TECH since the initial announcement of the Bid on October 9, 2023.²

The closing price of CMB.TECH on the New York Stock Exchange on October 8, 2024 is USD 17.34.

The bid price will be paid in cash. Shareholders tendering Belgian shares in the Reopening will receive an equivalent amount in euros, calculated using the WM/Reuters spot exchange rate for euros per U.S. dollar at 5:00 p.m. CET on the date of the announcement of the results of the acceptance period of the Reopening.

Given CMB.TECH’s listing on Euronext Brussels and the New York Stock Exchange, the Reopening will be comprised of two concurrent offers (i.e., a dual offer), structured as (i) a new U.S. tender offer for CMB.TECH shares held by U.S. holders (within the meaning of Rule 14d-1(d) under the Securities Exchange Act of 1934, as amended), conducted in accordance with applicable U.S. federal securities laws, and (ii) a reopening of the Belgian offer for CMB.TECH shares held by holders wherever located, conducted in accordance with applicable Belgian law.

The reopening of the Belgian offer will take place on the basis of a supplement to the Prospectus that has to be approved by the FSMA and shall be made public. In accordance with the order of the FSMA, the acceptance period of the Reopening is expected to open at the latest on 4 December 2024. The U.S. tender offer will be made upon the terms and subject to the conditions set forth in an offer to purchase, letter of transmittal and related documents that CMB will file as part of a tender offer statement on Schedule TO with the U.S. Securities and Exchange Commission.
