[8-K] Unity Biotechnology, Inc. Reports Material Event

Rhea-AI Filing Summary

Codexis, Inc. (CDXS) Form 4: 10% owner Opaleye Management Inc. reported an open-market purchase of 100,000 common shares on 07/18/2025 at $2.82 per share (≈ $282k). After the transaction, Opaleye now indirectly controls 12,450,000 shares through Opaleye L.P. and 250,000 shares through a separately managed account, totaling ≈ 12.7 million shares. No derivative positions were disclosed. Opaleye disclaims beneficial ownership beyond its pecuniary interest. As a Schedule 13D filer and 10% holder, continued accumulation can signal confidence and tighten the public float, although the added position represents <1 % of its existing stake.

Positive

• Insider accumulation: A 10% owner added 100,000 shares in the open market, often viewed as a vote of confidence.
• Stake increase: Total indirect holdings rise to ≈ 12.7 million shares, tightening float and aligning insider with shareholder value.

Negative

• Scale of purchase is small: The 100k-share buy raises the position by less than 1 %, so informational impact may be limited.

Insights

Securities Analyst

TL;DR: 10% owner bought 100k CDXS shares at $2.82, nudging stake to 12.7 M; small addition but positive insider signal.

Opaleye’s purchase increases its indirect ownership by roughly 0.8 %, bringing its total to about 12.7 million shares. While the dollar value is modest relative to its holding, insider buying—especially by a large shareholder—tends to be interpreted favorably because the investor is committing fresh capital at prevailing market prices. No dispositions or derivative exercises were reported, indicating a straightforward cash purchase. The filing is impactful mainly as a sentiment indicator; it does not alter Codexis’s fundamentals or capital structure but may support near-term share demand and investor confidence.

Item 1.01 Entry into a Material Definitive Agreement.

On July 22, 2025, Unity Biotechnology, Inc. (the “Company”) entered into a Purchase Agreement (the “Purchase Agreement”) with Craig R. Jalbert, the Company’s President and Secretary and sole director (in such capacity, the “Holder”), pursuant to which the Company agreed to issue and sell to the Holder one share of the Company’s newly designated Series A Preferred Stock, par value $0.0001 per share (the “Series A Preferred Share”), for a purchase price of $1.00. The Purchase Agreement contains customary representations, warranties and covenants between the parties. The closing of the sale and purchase of the Series A Preferred Share was completed on July 22, 2025.

The terms of the Series A Preferred Share are set forth in a Certificate of Designation of Series A Preferred Stock (the “Certificate of Designation”) filed with the Secretary of State of Delaware and effective on July 21, 2025. Additional information regarding the rights, preferences, privileges and restrictions applicable to the Series A Preferred Share is set forth under Item 5.03 of this report.

Pursuant to the Purchase Agreement, the Holder has agreed to cast the votes represented by the Series A Preferred Share on any Dissolution Proposal (defined below) in the same proportion as shares of common stock of the Company, par value $0.0001 per share (“Common Stock”), are cast for and against the Dissolution Proposal (provided that for the purposes of calculating such proportions (i) any broker non-votes and any abstentions will be treated as votes “against” the Dissolution Proposal, and (ii) any shares of Common Stock that are not voted on the Dissolution Proposal shall be excluded from such calculation). “Dissolution Proposal” means any proposal approved by the Company’s Board of Directors (the “Board”) and submitted to the vote of stockholders of the Company at a meeting of stockholders to approve the dissolution of the Company pursuant to Section 275 of the General Corporation Law of the State of Delaware (“DGCL”).

As previously disclosed, on June 27, 2025, the Board: (i) determined that it is in the best interests of the Company and its stockholders that the Company be dissolved in accordance with the DGCL pursuant to a Plan of Dissolution (the “Dissolution”); (ii) approved the Dissolution; and (iii) approved seeking stockholder approval of the Dissolution Proposal at a special meeting of stockholders (the “Special Meeting of Stockholders”) to be held as soon as reasonably practicable. If the Dissolution Proposal is approved, the Company intends to file a Certificate of Dissolution with the Secretary of State of the State of Delaware in accordance with Delaware law to initiate the dissolution process. The exact timing of such filing will be subject to the discretion of the Board.

The foregoing summary of the Purchase Agreement does not purport to be complete and is qualified in its entirety by the full text of the Purchase Agreement, a copy of which is filed as Exhibit 10.1 to this report.

Item 3.02. Unregistered Sales of Equity Securities.

The disclosure included in Item 1.01 and Item 5.03 of this report is incorporated under this Item by reference. The Purchaser is an “accredited investor” and the offer and sale of the Series A Preferred Share was exempt from registration under Section 4(a)(2) of the Securities Act of 1933, as amended. The Company was able to rely upon this exemption because this issuance does not constitute a public offering of its shares.

Item 3.03 Material Modification to Rights of Security Holders.

The disclosure included in Item 5.03 of this report is incorporated under this Item by reference. Prior to the issuance of the Series A Preferred Share, stockholder approval of any Dissolution Proposal required the affirmative approval of a majority of the outstanding shares of Common Stock. Following the issuance of the Series A Preferred Share, stockholder approval of any Dissolution Proposal requires affirmative approval from a majority of the voting power of the shares of Common Stock and the Series A Preferred Share, voting together as a single class. Holder will cast the votes represented by the Series A Preferred Share on the Dissolution Proposal in the same proportion as votes of shares of Common Stock are cast for or against the Dissolution Proposal. Prior to the issuance of the Series A Preferred Share, abstentions and any other non-votes would have had the same effect as a vote against the Dissolution Proposal. Following the issuance of the Series A Preferred Share, abstentions and any other non-votes on the Dissolution will still technically have the same effect as a vote against such proposal, but because the Series A Preferred Share has a high number of votes and will vote in a manner that mirrors votes actually cast by the holders of Common Stock (which does not include abstentions or any other non-votes), abstentions and any other non-votes are expected to have minimal effect on the outcome of the vote on the Dissolution Proposal.

Item 5.03. Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On July 21, 2025, the Company filed the Certificate of Designation of Series A Preferred Stock with the Secretary of State of the State of Delaware, which sets forth the rights, preferences and privileges of the Series A Preferred Share. The Certificate of Designation designates one share of the Company’s preferred stock as Series A Preferred, and establishes and designates the preferences, rights and limitations thereof. Pursuant to the Certificate of Designation:

Convertibility. The Series A Preferred Share is not convertible into, or exchangeable for, shares of any other class or series of stock or other securities of the Company.

Dividends. Upon the declaration of any dividend payable to holders of shares of capital stock of the Company, the Holder shall be entitled to receive an amount per share equal to $0.01 (payable out of funds legally available therefor), which amount shall be paid prior and in preference to any payment made to the holders of outstanding shares of the Common Stock.

Voting. The Series A Preferred Share will have 600,000,000 votes, but has the right to vote only on the Dissolution Proposal, and pursuant to the Share Purchase Agreement, the votes represented by the Series A Preferred Share must be voted in the same proportion as the votes of shares of Common Stock cast for or against such proposal. The Series A Preferred Share will vote together with the Common Stock as a single class on the Dissolution Proposal. The Series A Preferred Share has no other voting rights, except as may be required by the General Corporation Law of the State of Delaware.

Liquidation. Upon a liquidation, bankruptcy, reorganization, merger, acquisition, sale, dissolution or winding up of the Company pursuant to which assets of the Company or consideration received by the Company are to be distributed to the stockholders, the holder of the Series A Preferred Share will not be entitled to receive any such distributions.

Transfer Restrictions. The Series A Preferred Share may not be transferred at any time prior to stockholder approval the Dissolution Proposal without the prior written consent of the Company’s Board of Directors.

Automatic Transfer. The Series A Preferred Stock shall be transferred to the Company for no consideration automatically and with no further action required by the Company or the Holder immediately following the final adjournment of any meeting of stockholders at which the Company’s stockholders have approved the Dissolution Proposal. Following such automatic transfer, the Series A Preferred Share shall cease to be outstanding and the Holder shall cease to have any rights in respect thereof and the Series A Preferred Share shall be automatically retired and restored to the status of an authorized but unissued share of preferred stock of the Company.

The foregoing is only a summary of the terms of the Certificate of Designation and does not purport to be complete and is qualified in its entirety by reference to the text of the Certificate of Designation, a copy of which is filed as Exhibit 3.1 to this report and is incorporated herein by reference.
