Houston American SEC Filings

Grid Dynamics Holdings, Inc. (NASDAQ: GDYN) filed a Form 144 indicating that insider Yury Gryzlov intends to sell 2,000 common shares through Morgan Stanley Smith Barney LLC. The shares are valued at $24,660 and are expected to be sold on 07/08/2025. Gryzlov acquired the shares as restricted stock on 03/13/2021. The company has 84,547,653 shares outstanding, so the planned sale represents only about 0.002 % of the float.

Houston American Energy Corp. (HUSA) – Form 4 filing dated 07/03/2025

The filing discloses that Bower Family Holdings, LLC, already a 10% beneficial owner of HUSA, acquired an additional 3,066,580 shares of common stock on 07/01/2025. The acquisition, coded “P” on the form, was executed through the exchange of the reporting person’s units of Abundia Global Impact Group, LLC pursuant to a Share Exchange Agreement signed on 02/20/2025. Following the transaction, the reporting person now directly owns 5,246,760 HUSA shares, reinforcing its status as a significant insider.

No derivative securities were reported, and no sale or disposition occurred. The filing is signed by Kevin Bower as Managing Member of Bower Family Holdings.

• Form type: SEC Form 4 (Statement of Changes in Beneficial Ownership)
• Reporting person’s relationship to issuer: 10% Owner
• Nature of transaction: Share-for-share exchange (reflected as a purchase)
• Resulting ownership: 5.25 million shares, held directly

For investors, an increase in holdings by a >10% insider can be viewed as a vote of confidence and is a material ownership update that may influence sentiment and float dynamics.

Houston American Energy Corp (HUSA) – SEC Form 3 filing: Bower Family Holdings, LLC has filed an initial statement of beneficial ownership, disclosing direct ownership of 2,180,180 common shares. The filer is classified as a 10% owner, giving it significant influence under Section 16(a) rules. The report covers an event dated 11/11/2024 and is signed by Managing Member Kevin Bower on 07/03/2025. No derivative securities or additional ownership structures are reported.

This routine regulatory filing increases transparency regarding insider holdings but does not, by itself, indicate any change in Houston American’s operations, strategy, or financial performance. Investors may view the large stake as a potential vote of confidence, yet the document provides no purchase price, transaction details, or intent, limiting immediate valuation impact.

On 30 June 2025, GCM Grosvenor Inc. (ticker GCMG) director Samuel C. Scott III filed a Form 4 reporting the receipt of 6,380 fully-vested Restricted Stock Units (RSUs) under the company’s Amended & Restated 2020 Incentive Award Plan. The RSUs were taken in lieu of quarterly cash board compensation, aligning the director’s remuneration with shareholder interests. Each RSU converts 1-for-1 into Class A common stock and will be delivered upon the earliest of the director’s separation from service, a change-in-control event, or death/disability. The reference price listed is $11.56, valuing the grant at roughly $74 thousand. After this transaction, Mr. Scott beneficially owns 97,704 derivative securities (RSUs). The filing is coded “A,” indicating an acquisition with no open-market purchase. While the grant marginally increases insider ownership, its size is immaterial to the company’s overall capitalization and does not alter the investment thesis.

Houston American Energy Corp. (HUSA) – Form 4 insider filing

CEO, President and Director Peter F. Longo reported a board-approved award of 40,000 shares of common stock dated 30 June 2025. The transaction is coded as an acquisition ("A") at a stated price of $0.00 per share. A footnote clarifies that the shares have not yet been issued and will only be distributed once shareholders approve a future equity-incentive plan; Mr. Longo therefore disclaims current beneficial ownership of the grant. Should issuance occur, his direct holdings would rise to 51,917.48 shares.

No derivative securities were reported, and the form was filed solely by the reporting person on 1 July 2025. The filing signals prospective equity compensation rather than an open-market transaction, so there is no immediate impact on share count, cash flow or ownership percentages.

• Reporting person: Peter F. Longo
• Role: CEO, President, Director
• Shares granted: 40,000 common shares (contingent)
• Price: $0.00 per share
• Condition: Subject to shareholder approval of a future equity-incentive plan

Codexis, Inc. (CDXS) received a Form 4 filing from Opaleye Management Inc., a 10% beneficial owner, detailing an open-market purchase completed on 27 June 2025.

• Transaction: 100,000 shares of Codexis common stock were purchased (Code P) at an average price of $2.39 per share.
• Post-transaction holdings: Opaleye now reports 12,350,000 shares held indirectly through Opaleye, L.P. and an additional 250,000 shares in a separately managed account, bringing total reported beneficial ownership to 12.6 million shares.
• Ownership form: All shares are reported as indirect (Form I); the investment manager disclaims beneficial ownership beyond its pecuniary interest.
• Reporting party status: Opaleye is classified as a 10% owner; no board or executive role is indicated.

The filing signals incremental insider accumulation by a large shareholder. While the 100 k-share purchase is modest relative to the 12.35 million-share position, fresh buying can be interpreted by investors as a vote of confidence in Codexis at current price levels. No derivative transactions, sales or options were disclosed in this filing.
