Annex A to Form 12b-25

PART III - NARRATIVE

Cloudastructure, Inc., a Delaware corporation (the "Company"), was unable, without unreasonable effort or expense, to file its Quarterly Report on Form 10-Q ("Form 10-Q") for the quarter period ended March 31, 2026 ("Q1 2026"), on or prior to its original due date, May 15, 2026, for the reason set forth below.

The Company requires additional time to review and confirm the accounting treatment for its outstanding shares of Series 2 Convertible Preferred Stock. The Company expects and intends that this process will be completed in time for the Company to file the Form 10-Q no later than the fifth calendar day following the prescribed due date. It is possible the finalization of this analysis could result in a change to the method in which the Company is accounting for its outstanding shares of Series 2 Convertible Preferred Stock.

Cautionary Statement Regarding Forward-Looking Statements

Certain statements in this Form 12b-25, including those that express a belief, expectation or intention, as well as those that are not statements of historical fact, are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. This specifically includes the Company's expectation regarding the accounting treatment for its outstanding shares of Series 2 Convertible Preferred Stock.

These forward-looking statements are based on the Company's current expectations and are subject to risks and uncertainties, which could cause actual results to differ from those stated or implied by such forward-looking statements. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary from those indicated or anticipated by such forward-looking statements. The inclusion of forward-looking statements should not be regarded as a representation that such plans, estimates or expectations will be achieved. Important factors that could cause actual results to differ from such forward-looking statements include, among others, the completion of the Company's analysis regarding such accounting treatment, the possibility that the Company will not be able to file its Form 10-Q within the five-day extension permitted by the rules of SEC, the occurrence of subsequent events, and other risk factors detailed from time to time in the Company's reports filed with the SEC. The foregoing list of important factors is not exclusive.

Any forward-looking statements speak only as of the date of this Form 12b-25. The Company expressly disclaims any obligation to update any forward-looking statements, whether as a result of new information or developments, future events or otherwise, except as required by law. Readers are cautioned not to place undue reliance on any of these forward-looking statements.
