Founder Shares

On July 24, 2025, the Company issued an aggregate of 7,666,667 Class B ordinary shares, $0.0001 par value (the “Founder Shares”), in exchange for a $25,000 payment (approximately $0.00326 per share) from the Sponsor to cover certain expenses on behalf of the Company. As used herein, unless the context otherwise requires, Founder Shares shall be deemed to include the Public Shares issuable upon conversion thereof. The Founder Shares are identical to the Public Shares included in the Units being sold in the Initial Public Offering except that the Founder Shares automatically convert into Public Shares at the time of the Initial Business Combination (with such conversion taking place immediately prior to, simultaneously with, or immediately following the time of the Initial Business Combination, as may be determined by the directors of the Company) or earlier at the option of the holder and are subject to certain transfer restrictions, as described in more detail below. The Sponsor had agreed to forfeit up to an aggregate of 1,000,000 Founder Shares to the extent that the over-allotment option was not exercised in full by the underwriters so that the Founder Shares will represent 25% of the Company’s issued and outstanding shares after the Initial Public Offering. The Sponsor, officers, and directors will not be entitled to redemption rights with respect to any Founder Shares and any Public Shares held by them in connection with the completion of the Initial Business Combination. If the Initial Business Combination is not completed within 24 months from the closing of the Initial Public Offering, the Sponsor, officers, and directors will not be entitled to rights to liquidating distributions from the Trust Account

with respect to any Founder Shares and Private Placement Units (and any securities underlying the Private Placement Units) held by them. On November 3, 2025, the underwriters exercised their over-allotment option in full as part of the closing of the Initial Public Offering. As such, the 1,000,000 Founder Shares are no longer subject to forfeiture.

Certain of the Strategic Partners and Senior Advisors invested in KingsRock Viking Acquisition, LLC, and through it, indirectly in the Sponsor, thereby sharing in the appreciation of Founder Shares and Private Placement Units held by the Sponsor, provided that the Company successfully complete a Business Combination. However, such parties will have no right to control KingsRock Viking Acquisition, LLC or the Sponsor or participate in any decision regarding the disposal of any security held by the Sponsor prior to the consummation of a Business Combination. In addition, each of the Company’s four independent directors have purchased membership interests in KingsRock Viking Acquisition, LLC for $187 which will provide them with an indirect interest in 50,000 Founder Shares. In addition, one of the independent directors has purchased two other membership interests in KingsRock Viking Acquisition, LLC — one that he purchased for $250 which will provide him with an indirect interest in 66,666 Founder Shares, and the other that he purchased for $50,000 which will provide him with an indirect interest in 5,000 Private Placement Units. None of the independent directors will have a right to control either KingsRock Viking Acquisition, LLC or the Sponsor or participate in any decision regarding the disposal of any security held by the Sponsor, or otherwise, prior to the consummation of a Business Combination. The sale of the Founder Shares to the Company’s independent directors, are in the scope of FASB ASC Topic 718, “Compensation-Stock Compensation” (“ASC 718”). Under ASC 718, stock-based compensation associated with equity-classified awards is measured at fair value upon the grant date.

The third-party valuation firm valued the Founder Shares as of September 15, 2025. The probability of de-SPAC and instrument specific market adjustment was assumed to be 45.0%; the implied Class A ordinary share price was $9.82; volatility of 6.0%; and a discount for lack of marketability of 13.0%. The valuation has identified the fair value of the Founder Shares to be $3.84 per share as of grant date. The total fair value of the 200,000 Founder Shares purchased by the four independent directors and the additional 66,666 Founder Shares purchased by one of the directors is $1,023,997 or $3.84 per share. Because the agreements did not specify any vesting terms or performance conditions, the Founder Shares were considered fully vested upon execution of the agreements. Accordingly, the Company recognized the full share-based compensation expense of $1,023,997 on the grant date.

The Sponsor, officers, and directors agreed not to transfer, assign or sell any of their Founder Shares until the earlier to occur of (A) six months after the completion of the Initial Business Combination or (B) subsequent to the Initial Business Combination, the date on which the Company consummates a transaction which results in the shareholders having the right to exchange their shares for cash, securities, or other property subject to certain limited exceptions.

Registration Rights

The holders of Founder Shares, Private Placement Units (and their underlying securities) and Units that may be issued upon conversion of working capital loans (and their underlying securities), if any, and any Class A ordinary shares issuable upon conversion of the Founder Shares and any Class A ordinary shares held by the Sponsor, officers, and directors at the completion of the Initial Public Offering or acquired prior to or in connection with the Initial Business Combination, will be entitled to registration rights pursuant to a registration rights agreement to be signed with the initial shareholders and the representative of the underwriters prior to or on the effective date of the registration statement for the Initial Public Offering. These holders will be entitled to make up to three demands and have “piggyback” registration rights. The representative of the underwriters may not exercise its demand and “piggyback” registration rights after five and seven years, respectively, after the effective date of the registration statement of which the prospectus for the Initial Public Offering forms a part and may not exercise its demand rights on more than one occasion. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Administrative Support Agreement

Commencing on October 31, 2025, the date that the Company’s securities are first listed in New York Stock Exchange, the Company agreed to reimburse an affiliate of the managers of the Sponsor, KingsRock, in an amount equal to up to $30,000 per month for office space, utilities and secretarial and administrative support. Upon completion of the Initial Business Combination or the Company’s liquidation, the Company will cease paying these monthly fees. For the three months ended March 31, 2026, the Company incurred and paid $90,000 related to these services. During the year ended December 31, 2025, the Company incurred $60,000 under the administrative services agreement. As of March 31, 2026 and December 31, 2025, amounts outstanding under the administrative services agreement were $0 and $60,000, respectively, with the balances included in accrued expenses in the accompanying balance sheets.

Promissory Note

On July 24, 2025, the Company and the Sponsor entered into a loan agreement, whereby the Sponsor agreed to loan the Company an aggregate of up to $100,000 to cover expenses related to the Initial Public Offering pursuant to a promissory note (the “Note”). This loan was non-interest bearing and payable on the earlier of December 31, 2025, or the date on which the Company consummated the Initial Public Offering. As of November 3, 2025, the Company had borrowed $98,194, which was paid in full by the Company at the closing of the Initial Public Offering and the borrowings under the Note are no longer available.

Working Capital Loans

In addition, in order to finance transaction costs in connection with its Initial Business Combination, the Sponsor or an affiliate of the Sponsor, or the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes its Initial Business Combination, the Company would repay the Working Capital Loans. In the event that the Initial Business Combination does not close, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. If the Sponsor makes any Working Capital Loans, up to $1,500,000 of such loans may be convertible into units of the post business combination entity at a price of $10.00 per unit at the option of the lender. The units and their underlying securities would be identical to the Private Placement Units. As of March 31, 2026 and December 31, 2025, the Company had no borrowings under the Working Capital Loans.
