disclosures set forth under Item 2.03 are incorporated by reference.
Item
2.03. Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.
Pursuant
to the amended and restated memorandum and articles of association (the “Charter”) of the Columbus Acquisition Corp,
a Cayman Islands exempted company (the “Company”), the Company had until July 22, 2026 to complete its initial business
combination, however the Company may extend the period of time to consummate a business combination up to January 22, 2027, each by a
one-month extension, subject to the deposit of $50,000 (the “Monthly Extension Fee”) into the trust account of the
Company (the “Trust Account”).
On
July 21, 2026, an aggregate of $50,000 of the Monthly Extension Fee was deposited into the Trust Account for the public shareholders,
which enabled the Company to extend the period of time it has to consummate its initial business combination by one month from July 22,
2026 to August 22, 2026. Among the Monthly Extension Fee, $25,000 was paid by Hercules Capital Management VII Corp, a British Virgin
Islands company and the Sponsor of the Company (the “Sponsor”), and the remaining $25,000 was paid by WISeSat.Space
Corp., a British Virgin Islands business company (the “Target”) pursuant to that certain business combination agreement
dated as of November 9, 2025 (as it may be amended, supplemented, or otherwise modified from time to time, the “Business Combination
Agreement”) by and among the Company, WISeSat.Space Holdings Corp., a British Virgin Islands business company (“Pubco”),
WISeSat Merger Sub Corp., a Cayman Islands exempted company and a wholly owned subsidiary of Pubco (“Merger Sub”),
the Target, and WISeKey International Holding Ltd., a Swiss company (together with its successors, including after its anticipated domestication
to the British Virgin Islands prior to the Closing, the “Seller”).
On
July 30, 2026, the Company issued an unsecured promissory note in the principal amount of $25,000 to the Target in connection with the
Target’s payment of 50% of the Monthly Extension Fee (the “Target Extension Note”). On July 30, 2026, the Company
issued an unsecured promissory note in the principal amount of $25,000 to the Sponsor in connection with the Sponsor’s payment
of 50% of the Monthly Extension Fee (the “Sponsor Extension Note” and, together with the Target Extension Note, the
“Extension Notes”).
The
Target Extension Note bears no interest and is payable in full upon the earliest to occur of (i) the termination date of the Business
Combination Agreement in accordance with its terms other than by the Company pursuant to Section 10.1(e) thereof, (ii) the date on which
the Company consummates its initial business combination, including the proposed business combination with the Target (a “Business
Combination”), and (iii) the date that the winding up of the Company is effective. The Sponsor Extension Note bears no interest
and is payable in full upon the earlier of (i) the date on which the Company consummates its Business Combination, and (ii) the date
that the winding up of the Company is effective.
The
payee of each of the Extension Notes, or its registered assigns or successors in interest (the “Payee”), has the right,
but not the obligation, to convert the outstanding unpaid obligations payable to the Payee under the Extension Notes, as applicable,
in whole or in part, respectively, into private units (the “Conversion Units”) of the Company at a price of $10.00
per unit, each consisting of one ordinary share, par value $0.0001 per share (the “Ordinary Share”) and one right
to receive one-seventh (1/7) of one Ordinary Share upon the consummation of a Business Combination, as described in the prospectus of
the Company (File No: 333-283278).
Notwithstanding
the foregoing, with respect to the Target Extension Note, in the event of a valid termination of the Business Combination Agreement by
the Company pursuant to Section 10.1(e) thereof, upon the completion of a Business Combination of the Company with other targets, other
than the Target or its affiliate, the Payee, at its sole election, may choose (i) either repayment of the outstanding amount under the
Target Extension Note, or (ii) to convert the outstanding amount into common or ordinary shares of the post-closing public company in
such Business Combination (“Conversion Shares”) at a price per share equal to $5.00 (with such price to be equitably
adjusted if the Ordinary Shares, par value are subject to any share splits, share dividends, combinations, recapitalizations and the
like after the date of such Target Extension Note or are not converted into common or ordinary shares of the post-closing public company
in such Business Combination on a one-for-one basis).
The
issuance of the Extension Notes was made pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act
of 1933, as amended.
A
copy of the Target Extension Note is attached as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.
The foregoing description of the Target Extension Note does not purport to be complete and is subject to, and is qualified in its entirety
by, the full text of the Target Extension Note.
A
copy of the Sponsor Extension Note is attached as Exhibit 10.2 to this Current Report on Form 8-K and is incorporated herein by reference.
The foregoing description of the Sponsor Extension Note does not purport to be complete and is subject to, and is qualified in its entirety
by, the full text of the Sponsor Extension Note.
Item
3.02 Unregistered Sales of Equity Securities
The
information disclosed under Item 2.03 of this Current Report on Form 8-K is incorporated by reference into this Item 3.02 to the extent
required herein. The Conversion Units (and the underlying securities) issuable upon conversion of the Sponsor Extension Note, as applicable,
if any, (1) may not, subject to certain limited exceptions, be transferable or salable by the Sponsor until the completion of a Business
Combination and (2) are entitled to registration rights. The Conversion Units (and the underlying securities) and/or the Conversion Shares,
issuable upon conversion of the Target Extension Note, as applicable, if any, (1) may not, subject to certain limited exceptions, be
transferable or salable by the Target until the expiration of the Lock-up Period (as defined in the Lock-Up Agreement as defined in the
Business Combination Agreement) and (2) are entitled to registration rights.
Forward-Looking
Statements
This
Current Report on Form 8-K contains certain statements that are not historical facts and are forward-looking statements within the meaning
of the federal securities laws with respect to the proposed Business Combination, including without limitation statements regarding the
anticipated benefits of the proposed Business Combination, the anticipated timing of the proposed Business Combination, the implied enterprise
value, future financial condition and performance of the combined company after the Closing and expected financial impacts of the proposed
Business Combination, the satisfaction of closing conditions to the proposed Business Combination, the level of redemptions of the Company’s
public shareholders and the products and markets and expected future performance and market opportunities of the combined company. These
forward-looking statements generally are identified by the words “believe,” “project,” “expect,”
“anticipate,” “estimate,” “intend,” “think,” “strategy,” “future,”
“opportunity,” “potential,” “plan,” “seeks,” “may,” “should,”
“will,” “would,” “will be,” “will continue,” “will likely result,” and similar
expressions, but the absence of these words does not mean that a statement is not forward-looking. Forward-looking statements are predictions,
projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject
to risks and uncertainties.
These
forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on as,
a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult
or impossible to predict and will differ from assumptions. Many factors could cause actual future events to differ materially from the
forward-looking statements in this communication, including but not limited to: (i) the risk that the proposed Business Combination may
not be completed in a timely manner or at all, which may adversely affect the price of the Company’s securities; (ii) the risk
that the proposed Business Combination may not be completed by the Company’s business combination deadline; (iii) the failure to
satisfy the conditions to the consummation of the proposed Business Combination, including the approval of the Business Combination Agreement
by the shareholders of the Company, the satisfaction of the closing requirements and the receipt of certain governmental, regulatory
and third party approvals; (iv) the occurrence of any event, change or other circumstance that could give rise to the termination of
the Business Combination Agreement; (v) redemptions exceeding anticipated levels; (vi) the failure to meet Nasdaq initial listing standards
in connection with the consummation of the proposed Business Combination; (vii) the effect of the announcement or pendency of the proposed
Business Combination on the Target’s business relationships, operating results, and business generally; (viii) risks that the proposed
Business Combination disrupts current plans and operations of the Target and the Seller; (ix) the outcome of any legal proceedings that
may be instituted against the Company, Pubco, the Target or the Seller related to the Business Combination Agreement or the proposed
Business Combination; (x) changes in the markets in which the Target competes, including with respect to its competitive landscape, technology
evolution, or regulatory changes; (xi) changes in domestic and global general economic conditions; (xii) the risk that Pubco and the
Target may not be able to execute its growth strategies; (xiii) risks related to supply chain disruptions; (xiv) the risk that Pubco
may not be able to develop and maintain effective internal controls; (xv) costs related to the proposed Business Combination and the
failure to realize anticipated benefits of the proposed Business Combination or to realize estimated pro forma results and underlying
assumptions, including with respect to estimated shareholders redemptions; (xvi) the ability to recognize the anticipated benefits of
the proposed Business Combination and to achieve commercialization and development plans, and identify and realize additional opportunities,
which may be affected by, among other things, competition, the ability of the Target to grow and manage growth economically and hire
and retain key employees; (xvii) inability to achieve successful results or to obtain licensing of third-party intellectual property
rights for future discovery and development of the Target’s projects; (xviii) failure to commercialize products and achieve market
acceptance of such products; (xix) the risk that the Target will need to raise additional capital to execute its business plan, which
may not be available on acceptable terms or at all; (xx) the risk that Pubco, post-combination, experiences difficulties in managing
its growth and expanding operations; (xxi) the risk of product liability or regulatory lawsuits or proceedings relating to the Target’s
business; (xxii) risks associated with intellectual property protection; (xxiii) the risk that the Target is unable to secure or protect
its intellectual property; and (xxiv) those factors discussed in the Company’s and Pubco’s filings with the SEC and that
will be contained in the Registration Statement relating to the proposed Business Combination.
The
foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties
that will be described in the “Risk Factors” section of the Registration Statement on Form F-4 (the “Registration Statement”)
and the amendments thereto, and other documents to be filed by the Company and Pubco from time to time with the SEC. These filings identify
and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained
in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put
undue reliance on forward-looking statements, and while the Pubco and the Company may elect to update these forward-looking statements
at some point in the future, they assume no obligation to update or revise these forward-looking statements, whether as a result of new
information, future events or otherwise, except as required by applicable law. None of Pubco, the Seller, the Target or the Company gives
any assurance that Pubco, the Seller, the Target or the Company will achieve expectations. These forward-looking statements should not
be relied upon as representing Pubco’s, the Company’s, the Seller’s or the Target’s assessments as of any date
subsequent to the date of this Current Report. Accordingly, undue reliance should not be placed upon the forward-looking statements.
Additional
Information About the Proposed Business Combination and Where to Find It

SEC, including the Registration Statement, which will include a proxy statement of the Company and a prospectus for the registration
of Pubco securities in connection with the Business Combination.
THE
PARTIES URGE THEIR INVESTORS, SHAREHOLDERS, AND OTHER INTERESTED PERSONS TO READ, WHEN AVAILABLE, THE PRELIMINARY PROXY STATEMENT/PROSPECTUS
AND DEFINITIVE PROXY STATEMENT/PROSPECTUS, IN EACH CASE WHEN FILED WITH THE SEC AND DOCUMENTS INCORPORATED BY REFERENCE THEREIN BECAUSE

the registration statement is declared effective by the SEC, the definitive proxy statement/prospectus and other relevant documents will
be mailed to the shareholders of the Company as of the record date in the future to be established for voting on the Business Combination
and will contain important information about the Business Combination and related matters. Shareholders of the Company and other interested
persons are advised to read, when available, these materials (including any amendments or supplements thereto) and any other relevant
documents in connection with the Company’s solicitation of proxies for the meeting of shareholders to be held to approve, among
other things, the Business Combination, because they will contain important information about the Company, Pubco, the Seller and the
Business Combination. Shareholders and other interested persons will also be able to obtain copies of the preliminary proxy statement/prospectus,
the definitive proxy statement/prospectus, and other relevant materials in connection with the Business Combination, without charge,
once available, at the SEC’s website at www.sec.gov or by directing a request to: Columbus Acquisition Corp, 14 Prudential Tower,

8-K.

Company, Pubco, the Seller, and their respective directors, executive officers, other members of management, and employees, under SEC
rules, may be deemed participants in the solicitation of proxies of the Company’s shareholders in connection with the Business
Combination. Investors and security holders may obtain more detailed information regarding the names and interests in the Business Combination

officers is also available in the Company’s filings with the SEC.
