share exchange, asset acquisition, share purchase, reorganization or similar initial business combination from June 12, 2026 to June

12, 2027 (the “Extended Date”), or an earlier date than the Extended Date as determined by the Company’s board of directors

Registrar of Companies

Grand Cayman

Centurion Acquisition Corp. (ROC

#406352) (the “Company”)

TAKE NOTICE that by minutes of an extraordinary general

meeting of the Company dated 12 June 2026, the following special resolution was passed:

4 The Extension Proposal

Resolved, as a special resolution

THAT, effective immediately, the Amended and Restated Memorandum and Articles of Association of the Company be amended by amending Article

51.7 as follows:

“In the event that the Company

does not consummate a Business Combination on or before June 12, 2027 (the “Deadline Date”), or by such earlier date as the

Directors may determine (in their sole discretion), or such later time as the Members may approve by Special Resolution in accordance

with the Articles, the Company shall as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public

Shares, at a per-Share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest

earned on the funds held in the Trust Account and not previously released to the Company (less taxes payable and up to US$100,000 of

interest to pay dissolution expenses), divided by the number of then Public Shares in issue, which redemption will completely extinguish

public Members’ rights as Members (including the right to receive further liquidation distributions, if any), subject to its obligations

under Cayman Islands law to provide for claims of creditors and other requirements of Applicable Law.”

5 The Adjournment Proposal

“RESOLVED, as an ordinary resolution, to approve

the adjournment of the Extraordinary General Meeting to a later date or dates, if necessary or convenient, to permit further solicitation

and vote of proxies in the event that there are insufficient votes for, or otherwise in connection with, the approval of the Extension

Proposal, or if we otherwise determine that additional time is necessary to effectuate the Extension.”
