**EXTRAORDINARY GENERAL MEETING OF SHAREHOLDERS

TO BE HELD ON JUNE 20, 2025

To our Shareholders:

Notice is hereby given that the Extraordinary General Meeting of Shareholders (the “Extraordinary General Meeting”) of Black Hawk Acquisition Corporation, a Cayman Islands exempted company (the “Company,” “Black Hawk”, “our,” “we” or “us”), will be held as a “virtual meeting” via audio teleconference only on June 20, 2025, at 12 p.m. Eastern Time for the following purposes, as more fully described in the accompanying proxy statement (the “Proxy Statement”):

(1)Extension Amendment Proposal—A proposal, by special resolution to amend the Company’s Second Amended and Restated Memorandum and Articles of Association (the “Existing Charter”) by adopting an amendment to the Existing Charter in the form set forth in Annex A to the Proxy Statement (the “Extension Amendment”) which reflects the extension of the date by which the Company must consummate a business combination (the “Combination Period”) up to eighteen (18) times from June 22, 2025 (the “Termination Date”) to December 22, 2026, each by an additional one (1) month (each an “Extension”) for a total of eighteen (18) months after the Termination Date (i.e., for a total of up to thirty-three (33) months after the consummation of its initial public offering (the “IPO”)), assuming a Business Combination has not occurred. The end date of each Extension shall be referred to herein as the “Extended Date.” We refer to this proposal as the “Extension Amendment Proposal”.
(2)Trust Agreement Amendment Proposal—A proposal to further amend The Company’s investment management trust agreement, dated as of March 20, 2024, (the “Trust Agreement”), by and between the Company and Continental Stock Transfer & Trust Company (the “Trustee”), to allow the Company to extend the Termination Date up to eighteen (18) times for an additional one (1) month each time from the Termination Date to December 22, 2026 (the “Trust Agreement Amendment”) by depositing into the trust account (the “Trust Account”) an amount equal to $0.033 multiplied by the number of ordinary shares sold to the public in the Company’s initial public offering and that remain outstanding after giving effect to the shares that are redeemed in connection with the vote on the Extension Amendment Proposal for each one-month extended, up to $55,000 per one-month extension (the “Trust Agreement Amendment Proposal”).
(3)Adjournment Proposal—A proposal, by ordinary resolution to adjourn the Extraordinary General Meeting to a later date or dates, if necessary, to permit further solicitation and vote of proxies if, based upon the tabulated vote at the time of the Extraordinary General Meeting, there are not sufficient votes to approve the Extension Amendment Proposal, the Trust Agreement Amendment Proposal or to provide additional time to effectuate the Extension Amendment and Extension (the “Adjournment Proposal”).

The Extension Amendment Proposal, Trust Agreement Amendment Proposal and the Adjournment Proposal are more fully described in the accompanying proxy statement. Please take the time to read carefully each of the proposals in the accompanying proxy statement before you vote.

The purpose of the Extension Amendment Proposal, the Trust Agreement Amendment Proposal and, if necessary, the Adjournment Proposal, is to allow us more time, if necessary, to complete our business combination. The Current Termination Date is June 22, 2025. As previously disclosed and as discussed in more detail in the accompanying proxy statement, the Company has entered into a definitive agreement for its initial business combination with Vesicor Therapeutics, Inc., a California corporation (“Vesicor”), and is in the process of seeking to consummate such business combination. However, it is possible that we will not be able to complete such a business combination by such date. Without the Extension, if we are unable to complete a business combination on or before June 22, 2025, we would be precluded from completing an initial business combination and, among other things, would be required to cease all operations and ultimately liquidate and dissolve the Company. Accordingly, our Board believes that it is advisable and in the best interest of the Company and our shareholders to obtain the Extension in case it becomes necessary to consummate our initial business combination. Notwithstanding the foregoing, we may decide to abandon the Extension Amendment Proposal at any time and for any reason prior to effectuating the Extension.

In connection with the Extension Proposal, holders of the Company’s ordinary shares, par value $0.0001 per share (“Ordinary Shares”) who purchased their ordinary shares as part of units sold in the Company’s initial public offering (the “IPO”, such units the “Public Units” and such Ordinary Shares, the “Public Shares”, the holders thereof the “Public Shareholders”) may elect to redeem their Public Shares for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the account established in connection with the IPO and into which certain amount of the net proceeds of the IPO, together with certain of the proceeds of a private placement of units (the “Private Placement”, such units the “Private Placement Units”, the Private Placement Units collectively with the Public Units the “units”) simultaneously with the closing date of the IPO, was deposited (the “Trust Account”), without giving effect to interest that may be withdrawn to pay tax obligations, divided by the number of the then outstanding Public Shares, and which election we refer to as an “Election.” An Election can be made regardless of whether such Public Shareholders vote “FOR” or “AGAINST” the Extension Proposal or do not vote at all, or do not instruct their broker or bank how to vote, at the Extraordinary General Meeting. The Public Shareholders may make an Election regardless of whether such Public Shareholders were holders as of the record date for the Extraordinary General Meeting. Public shareholders who do not make the Election would be entitled to have their shares automatically redeemed for cash if we do not complete our initial business combination by the Extended Date.

WE ARE NOT ASKING YOU TO VOTE ON OUR BUSINESS COMBINATION AT THIS TIME. IF THE EXTENSION AMENDMENT AND THE TRUST AMENDMENT ARE IMPLEMENTED AND YOU DO NOT ELECT TO REDEEM YOUR PUBLIC SHARES NOW, YOU WILL RETAIN THE RIGHT TO VOTE ON THE BUSINESS COMBINATION WHEN IT IS SUBMITTED TO SHAREHOLDERS AND THE RIGHT TO REDEEM YOUR PUBLIC SHARES INTO A PRO RATA PORTION OF THE TRUST ACCOUNT IN THE EVENT A BUSINESS COMBINATION IS APPROVED AND COMPLETED (AS LONG AS YOUR ELECTION IS MADE AT LEAST TWO (2) BUSINESS DAYS PRIOR TO THE MEETING AT WHICH THE SHAREHOLDERS’ VOTE IS SOUGHT) OR THE COMPANY HAS NOT CONSUMMATED THE BUSINESS COMBINATION BY THE EXTENDED DATE.

If the Extension Proposal is not approved, we may not be able to consummate our business combination. We urge you to vote at the Extraordinary General Meeting regarding the Extension Proposal.

Based upon the amount in the Trust Account as of June 2, 2025, the Record Date, which was approximately $73,379,601.56, we anticipate that the per-share price at which Public Shares will be redeemed from cash held in the Trust Account will be approximately $10.63 at the time of the Extraordinary General Meeting. The closing price of the Company’s Ordinary Shares on June 2, 2025 was $10.60. Accordingly, if the market price were to remain the same until the date of the meeting, exercising redemption rights would result in a public shareholder receiving approximately $0.03 less than if the shareholder sold such shares in the open market. However, the actual market price on the redemption date may be higher or lower than the per share pro rata portion of the Trust Account on such date. Additionally, the Company cannot assure shareholders that they will be able to sell their Ordinary Shares in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in its securities when such stockholders wish to sell their shares.

TO DEMAND REDEMPTION, PRIOR TO 5:00 P.M. EASTERN TIME ON JUNE 18, 2025, TWO BUSINESS DAYS BEFORE THE EXTRAORDINARY GENERAL MEETING, YOU SHOULD ELECT EITHER TO PHYSICALLY TENDER YOUR SHARE CERTIFICATES TO CONTINENTAL STOCK TRANSFER & TRUST COMPANY OR TO DELIVER YOUR SHARES TO THE TRANSFER AGENT ELECTRONICALLY USING DTC’S DWAC (DEPOSIT/WITHDRAWAL AT CUSTODIAN), AS DESCRIBED HEREIN. YOU SHOULD ENSURE THAT YOUR BANK OR BROKER COMPLIES WITH THE REQUIREMENTS IDENTIFIED ELSEWHERE HEREIN.

If the Extension Proposal is not approved and we do not consummate a business combination by June 22, 2025, as contemplated by our IPO prospectus and in accordance with the Existing Charter, we will (i) cease all operations except for the purpose of winding up, (ii) 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 us to pay our taxes (less up to $100,000 of interest to pay dissolution expenses and net of taxes payable), divided by the number of the then outstanding Public Shares, which redemption will completely extinguish the rights of the Public Shareholders as shareholders (including the right to receive further liquidation distributions, if any); and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and our Board, liquidate and dissolve, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and to the other requirements of applicable law.

There will be no redemption rights or liquidating distributions with respect to our rights, each of which will automatically convert into one ordinary share upon consummation of a business combination (“rights”), which rights will expire worthless in the event of our winding up. In the event of a liquidation, Black Hawk Management LLC (the “Sponsors”), officers, directors and our other initial shareholders have agreed that they will not receive any monies held in the Trust Account as a result of their ownership of shares issued to them prior to the IPO (the “Founder Shares” and, together with the Public Shares, the “ordinary shares” or “shares”) or the Ordinary Shares included in the Private Units (the “Private Shares”).

The Adjournment Proposal, if adopted, will allow our Board to adjourn the Extraordinary General Meeting to a later date or dates if we determine such additional time is necessary to effectuate the Extension. The Adjournment Proposal will only be presented to our shareholders in the event that we determine additional time is necessary to effectuate the Extension Amendment Proposal.

The approval of the Extension Amendment Proposal requires a special resolution under the Existing Charter, being a resolution passed by at least two-thirds of the votes cast by the shareholders who, being present in person (including virtually) or by proxy, and entitled to vote at the Extraordinary General Meeting, vote at the Extraordinary General Meeting.

The approval of the Adjournment Proposal requires an ordinary resolution under the Existing Charter, being a resolution passed by a simple majority of the votes cast by the shareholders who, being present in person (including virtually) or by proxy and entitled to vote at the Extraordinary General Meeting, vote at the Extraordinary General Meeting.

Based on the amount in trust as of June 2, 2025, the current per share redemption price is approximately $10.63, without giving effect to interest that may be withdrawn to pay tax obligations.

The Board has fixed the close of business on June 2, 2025 as the record date (the “Record Date”) for determination of Shareholders entitled to notice and to vote at the Extraordinary General Meeting and any adjournment thereof. Holders of our Class A ordinary shares are entitled to vote at the Extraordinary General Meeting.

Pursuant to rules adopted by the Securities and Exchange Commission (the “SEC”), we have elected to provide access to our proxy materials via the Internet. Accordingly, we will send our Shareholders a Notice of Internet Availability of Proxy Materials (the “Notice”) containing instructions on how to access our 2025 Proxy Statement and our annual report on Form 10-K for the fiscal year ended November 30, 2024 online. Shareholders who have received the Notice will not be sent a printed copy of our proxy materials in the mail unless they request to receive a printed copy.

You will be able to attend the Extraordinary General Meeting via audio teleconference only using the following dial-in information below on June 20, 2025, at 12 p.m. Eastern Time.

Your vote is important. Whether or not you plan to attend the Extraordinary General Meeting, please vote your shares by promptly completing, signing and returning the enclosed proxy card. You may also vote your shares over telephone or the Internet in accordance with the instructions on the proxy card. Any Shareholder attending the Extraordinary General Meeting may vote in person at the virtual meeting, even if you have already returned a proxy card or voting instruction card.
