Rhea-AI Filing Summary

Cloudastructure, Inc. (CSAI) – Form 4 filing: Founder, director and 10% owner Sheldon Richard Bentley reported two open-market sales of Class A common stock.

• 21 Jul 2025: 16,782 shares sold at a weighted-average $1.87 (price range $1.855-$1.88). Shares directly owned after the trade: 61,399.
• 22 Jul 2025: 16,962 shares sold at a weighted-average $1.83 (price range $1.81-$1.85). Shares directly owned after the trade: 44,437.

Total shares disposed: 33,744, reducing Bentley’s direct holdings by ~43 % from 78,181 to 44,437. Estimated gross proceeds are about $62.9 k. No derivative securities were involved.

Implication: A sizeable sale by a founder-level insider can be interpreted as a cautious signal and may weigh on short-term sentiment, although Bentley remains a >10 % shareholder.

Positive

• None.

Negative

• Founder/10 % owner sold 33,744 shares (~43 % of his stake), potentially signalling lower insider confidence and applying downward pressure on the stock.

Insights

Securities Analyst

TL;DR Large founder sale (~43 %) is a mildly bearish signal for near-term CSAI sentiment.

The disposition trims the insider’s stake from 78 k to 44 k shares, suggesting reduced risk appetite or liquidity needs. While proceeds are modest, the trade size is material relative to the float of a micro-cap. Such selling often precedes muted price performance, especially absent offsetting positive catalysts. Investors should monitor further insider activity and forthcoming corporate updates.

Corporate Governance Expert

TL;DR Founder remains a 10 % holder but divestiture raises governance & alignment questions.

Founders typically signal commitment through sustained ownership. A near-half reduction may weaken perceived alignment with minority shareholders. However, Bentley continues to hold a significant block, limiting immediate control shifts. No red flags on reporting timeliness; Form 4 filed within the two-day window. Investors should watch for pattern selling that could erode governance confidence.

Item 4. Description of Securities.

Not applicable.

Item 5. Interests of Named Experts and Counsel.

Not applicable.

Item 6. Indemnification of Directors and Officers.

The Florida Business Corporation Act, as amended (the “FBCA”) permits, under certain circumstances, the indemnification of officers, directors, employees and agents of a corporation with respect to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, to which such person was or is a party or is threatened to be made a party, by reason of his or her being an officer, director, employee or agent of the corporation, or is or was serving at the request of, such corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against liability incurred in connection with such proceeding, including appeals thereof; provided, however, that the officer, director, employee or agent acted in good faith and in a manner that he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, or that he or she reasonably believed was not unlawful. In the case of proceedings by or in the right of the corporation, the FBCA provides for indemnification of any person by reason of the fact that such person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of, such corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against liability incurred in connection with such proceeding, including appeals thereof; provided, however, that the officer, director, employee or agent acted in good faith and in a manner that he or she reasonably believed to be in, or not opposed to, the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The termination of any such third-party action by judgment, order, settlement, or conviction or upon a plea of nolo contendere or its equivalent does not, of itself, create a presumption that the person (i) did not act in good faith and in a manner which he or she reasonably believed to be in, or not opposed to, the best interests of the corporation or (ii) with respect to any criminal action or proceeding, had reasonable cause to believe that his or her conduct was unlawful.

In the case of proceedings by or in the right of the corporation, the FBCA permits for indemnification of any person by reason of the fact that such person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of, such corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against liability incurred in connection with such proceeding, including appeals thereof; provided, however, that the officer, director, employee or agent acted in good faith and in a manner that he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, except that no indemnification is made where such person is adjudged liable, unless a court of competent jurisdiction determines that, despite the adjudication of liability but in view of all circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper.

To the extent that such person is successful on the merits or otherwise in defending against any such proceeding, Florida law provides that he or she shall be indemnified against expenses actually and reasonably incurred by him or her in connection therewith.

Our bylaws contain indemnification provisions similar to the FBCA, and further provide that we may purchase and maintain insurance on behalf of directors, officers, employees and agents in their capacities as such, or serving at the request of the corporation, against any liabilities asserted against such persons whether or not we would have the power to indemnify such persons against such liability under our bylaws.

Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, may be permitted to our directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that, in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Item 9. Undertakings.

(a) The Company hereby undertakes:

(1)           To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i)            To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii)           To reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement; and

(iii)          To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement;

Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) above do not apply if the registration statement is on Form S-8, and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Company pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this Registration Statement.

(2)            That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)            To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b)            The undersigned Company hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Company’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c)            Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Company pursuant to the foregoing provisions, or otherwise, the Company has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Company of expenses incurred or paid by a director, officer or controlling person of the Company in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Company will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
