Exhibit 99.4

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

Defined terms included below and not otherwise defined in this Exhibit 99.4 have the same meaning as terms defined and included elsewhere in the Current Report on Form 8-K (the “Form 8-K”) filed with the Securities and Exchange Commission (the “SEC”) on December 29, 2023.

The unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X and presents the combination of the historical financial information of Old Nukk and Brilliant, adjusted to give effect to the Business Combination and the other events contemplated by the Merger Agreement. Unless otherwise indicated or the context otherwise requires, references to “the Company” refer to Nukkleus and its consolidated subsidiaries after giving effect to the Business Combination.

The unaudited pro forma condensed combined balance sheet as of June 30, 2023 combines the historical balance sheet of Old Nukk as of June 30, 2023 and Brilliant as of June 30, 2023, on a pro forma basis as if the Business Combination and the other events contemplated by the Merger Agreement had been consummated on June 30, 2023. The unaudited pro forma condensed combined statement of operations for the year ended September 30, 2022 combines the historical statement of operations of Old Nukk for the year ended September 30, 2022 and the historical statement of operations of Brilliant for the year ended December 31, 2022 on a pro forma basis as if the Business Combination and the other events contemplated by the Merger Agreement had been consummated on October 1, 2021, the beginning of the earliest period presented. The unaudited pro forma condensed combined statement of operations for the nine months ended June 30, 2023 combines the historical statement of operations of Old Nukk for the nine months ended June 30, 2023, and the historical statement of operations of Brilliant for the nine months ended June 30, 2023 on a pro forma basis as if the Business Combination and the other events contemplated by the Merger Agreement had been consummated on October 1, 2021, the beginning of the earliest period presented.

The unaudited pro forma condensed combined financial information has been presented for illustrative purposes only and is not necessarily indicative of the financial position and operating results that would have been achieved had the Business Combination and the other events contemplated by the Merger Agreement occurred on the dates indicated. The unaudited pro forma condensed combined financial information does not purport to project the future financial position or operating results of the Company following the completion of the Business Combination and the other events contemplated by the Merger Agreement and may not be useful in predicting the future financial condition and results of operations of the Company following the Closing. The actual financial position and results of operations may differ significantly from the pro forma amounts reflected in this Exhibit 99.4 on Form 8-K due to a variety of factors. Assumptions and estimates underlying the unaudited pro forma adjustments included in the unaudited pro forma condensed combined financial statements are described in the accompanying notes. The unaudited pro forma adjustments represent management’s estimates based on information available as of the date on which these unaudited pro forma condensed combined financial statements are prepared and are subject to change as additional information becomes available and analyses are performed. Management considers this basis of presentation to be reasonable under the circumstances.

The unaudited pro forma condensed combined financial information was derived from and should be read together with the accompanying notes to the unaudited pro forma condensed combined financial statements, audited and unaudited financial statements of Old Nukk and Brilliant, the sections of the Joint Proxy Statement/Prospectus titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations of Nukkleus” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations of Brilliant,” and other information relating to Old Nukk and Brilliant included or incorporated by reference in this Form 8-K.

Accounting for the Business Combination

The Business Combination was accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, Brilliant was treated as the acquired company and Old Nukk was treated as the acquirer for financial reporting purposes. Accordingly, for accounting purposes, the financial statements of the Company represent a continuation of the financial statements of Old Nukk, with the Business Combination treated as the equivalent of Old Nukk issuing stock for the net assets of Brilliant, accompanied by a recapitalization. The net assets of Brilliant are stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Business Combination are those of Old Nukk. Old Nukk has been determined to be the accounting acquirer based on an evaluation of the following facts and circumstances:

● Old Nukk’s existing stockholders have a majority of the voting power;

● the Company’s Board consists of six directors, of which six were designated by Old Nukk and one was designated by Brilliant;

● Old Nukk’s existing senior management team will comprise the senior management of the Company; and

● Old Nukk’s operations prior to the Business Combination comprise the ongoing operations.

Pro Forma Capitalization Following the Business Combination

Upon the closing of the Business Combination, public shareholders were offered the opportunity to redeem all or a portion of such shareholder’s public shares for cash equal to their pro rata share of the aggregate amount on deposit (as of two business days prior to the Closing) in the Brilliant trust account. The unaudited condensed combined pro forma financial information reflects actual redemptions of 330,345 shares of Brilliant’s Class A Ordinary Shares at approximately $11.57 per share, or $3.8 million in the aggregate.

The following summarizes the pro forma capitalization of the Company immediately after the Business Combination and the other events contemplated by the Merger Agreement:

The Business Combination was accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, Brilliant was treated as the “acquired” company for financial reporting purposes.

The net assets of Brilliant are stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Business Combination are those of Old Nukk.

3. Loss per Share

Represents the net loss per share calculated using the historical weighted average shares of Old Nukk common stock outstanding, and the issuance of additional shares in connection with the Business Combination and the other events contemplated by the Merger Agreement, assuming the shares were outstanding since October 1, 2021. As the Business Combination and the other events contemplated by the Merger Agreement are being reflected as if they had occurred at the beginning of the period presented, the calculation of weighted average shares outstanding for basic and diluted net loss per share assumes that the shares issuable in connection with the Business Combination and the other events contemplated by the Merger Agreement have been outstanding for the entire period presented. No unexercised stock options and warrants were included in the earnings per share calculation as they would be anti-dilutive.
