On October 27, 2023, Catalyst entered into a Securities Purchase Agreement (the “Securities Purchase Agreement”) for a private placement with GNI USA (the “Private Placement”). Pursuant to the Securities Purchase Agreement, GNI USA agreed to purchase an aggregate of 8,110,000 units (the “Units”) representing (i) 811 shares of Gyre’s Series X Convertible Preferred Stock, par value $0.001 per share (the “Convertible Preferred Stock”) and (ii) warrants to purchase up to 811 shares of the Convertible Preferred Stock (the “Warrants”). The purchase price for each Unit was $0.6165, for an aggregate purchase price of approximately $5.0 million. The Private Placement closed on October 30, 2023.

The Warrants are immediately exercisable at an exercise price of $4,915.00 per share of Convertible Preferred Stock, subject to adjustments as provided under the terms of the Warrants, and expire October 30, 2033.

The Securities Purchase Agreement provides that Gyre will register the resale of the shares of common stock, par value $0.001 per share, of Gyre (the “Common Stock”) issuable upon conversion of the Convertible Preferred Stock into Common Stock. Gyre is required to prepare and file a registration statement with the SEC as promptly as reasonably practicable following the closing of the Private Placement, and to use its reasonable best efforts to have the registration statement declared effective as soon as practicable.

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

Amendment to the Certificate of Incorporation

At the Special Meeting, Catalyst’s stockholders approved (i) the adoption of an amendment to the certificate of incorporation of Catalyst in connection with the Authorized Share Increase and (ii) the adoption of an amendment to the certificate of incorporation of Catalyst to effect a reverse stock split of the Common Stock with a ratio of not less than 1-for-10 and not more than 1-for-60. Following the Special Meeting, the board of directors of Catalyst approved the Reverse Stock Split with a ratio of 1-for-15.

On October 27, 2023, prior to the Closing, Catalyst filed a certificate of amendment to Catalyst’s Fourth Amended and Restated Certificate of Incorporation (the “Certificate of Amendment”) with the Secretary of State of the State of Delaware to effect the Authorized Share Increase, the Reverse Stock Split and the Name Change, each with an effective time of 12:01 a.m. Eastern Time on October 30, 2023 (the “Effective Time”).

As of the Effective Time, each 15 shares of Common Stock outstanding immediately prior to the Effective Time was combined and reclassified, automatically and without any action on the part of Gyre or its stockholders, into one new share of Common Stock. No fractional shares of Common Stock was issued as a result of the Reverse Stock Split. In lieu of any fractional shares to which a stockholder of record would otherwise be entitled, Gyre paid cash (without interest and subject to withholding taxes, as applicable) equal to such fraction multiplied by the average of the high and low trading prices of the Common Stock on The Nasdaq Capital Market during regular trading hours for the five trading days immediately preceding the Effective Time (as adjusted in good faith by Gyre to account for the Reverse Stock Split ratio).

The Common Stock will commence trading on a split-adjusted basis, under the ticker symbol “GYRE,” at the open of trading on October 31, 2023, at which time the Common Stock will be represented by a new CUSIP number, 403783 103. The par value per share of the Common Stock will remain unchanged.

In addition, effective as of the Effective Time and as a result of the Reverse Stock Split, proportionate adjustments were made in accordance with the terms of the 2023 Omnibus Incentive Plan to the number of shares subject to outstanding equity awards, the per-share exercise or purchase price (if any) with respect to those awards, and the number of shares of Common Stock reserved for future issuance under the 2023 Omnibus Incentive Plan.

The foregoing description of the Certificate of Amendment is not complete and is subject to and qualified in its entirety by reference to the Certificate of Amendment, a copy of which is attached hereto as Exhibit 3.1 and is incorporated herein by reference.

Amendment to Certificate of Designation

On October 30, 2023, prior to the Closing, Gyre filed an amendment to Certificate of Designation of Preferences, Rights and Limitations of Series X Convertible Preferred Stock (the “Certificate of Designation” and such amendment, the “Amendment to Certificate of Designation”) with the Secretary of State of the State of Delaware in connection with the Private Placement, effective on October 30, 2023. Among other things, the Amendment to Certificate of Designation (i) increased the number of shares of preferred stock designated as Series X Convertible Preferred Stock and (ii) deleted Section 6(d)(iii) of the Certificate of Designation, which required Catalyst to pay an amount equal to the Fair Value (as defined in the Certificate of Designation) of the shares of common stock to be delivered upon conversion of the Convertible Preferred Stock in the event that Catalyst did not deliver such shares within three Trading Days (as defined in the Certificate of Designation) of the date that Catalyst was required to deliver such shares of common stock.

The foregoing description of the Amendment to Certificate of Designation is not complete and is subject to and qualified in its entirety by reference to the Amendment to Certificate of Designation, a copy of which is attached hereto as Exhibit 3.2 and is incorporated herein by reference.

Amended and Restated Bylaws

On October 30, 2023, in connection with the Transactions and with the new SEC rules regarding universal proxy cards and certain recent amendments to the Delaware General Corporation Law (the “DGCL”), the Board adopted an amendment and restatement of Gyre’s Amended and Restated Bylaws (as so amended and restated, the “Amended and Restated Bylaws”), effective as of such date, in order to, among other things:

•

update the procedural and disclosure requirements for director nominations made and business proposals submitted by stockholders (other than proposals submitted pursuant to Rule 14a-8 under the Exchange Act), to require, among other things:

with respect to director nominations, certain representations regarding engaging in solicitation with respect to such nomination and certain related documentation and confirmations;

certain information and representations to be included in a stockholder’s notice of a director nomination or other business, including information regarding the stockholder’s ownership interests in Gyre;

that a stockholder soliciting proxies from other stockholders use a proxy card color other than white; and

that any stockholder submitting a director nomination or other business proposal must comply with applicable Exchange Act requirements, and to clarify Gyre’s ability to disregard such nomination or proposal in the event such stockholder does not so comply;

•

reflect recent amendments to the DGCL, including to update procedures regarding stockholder meeting adjournment, notice and stockholder lists, implement an emergency bylaw, update procedures regarding electronic notice applicable to stockholder meetings and opt out of DGCL Section 116 regarding electronic delivery of documents or information;

•

remove the requirement that the Board consist of between three and 13 directors and to clarify that the stockholder vote required to elect a director is the plurality of votes cast;

•

update various provisions regarding meetings of the Board, committees of the Board and Gyre’s officers;

•

clarify certain procedures and standards of conduct with respect to indemnification and advancement of expenses to directors and officers; and

•

make various other updates, including clarifying, ministerial and conforming changes.

The foregoing description of the Amended and Restated Bylaws is not complete and is qualified in its entirety by reference to the full text of the Amended and Restated Bylaws, a copy of which is attached hereto as Exhibit 3.3 and is incorporated herein by reference.

Item 5.05 Amendments to the Registrant’s Code of Ethics, or Waiver of a Provision of the Code of Ethics.

On October 30, 2023, in connection with the Transactions, the Board adopted a new Code of Business Conduct and Ethics (the “Code of Conduct”), effective as of such date. The Code of Conduct supersedes the existing Code of Business Conduct and Ethics, as previously adopted by the board of directors of Catalyst on October 14, 2015 (the “Original Code of Conduct”). The Code of Conduct applies to all directors, officers and employees of Gyre and is intended to enhance understanding of Gyre’s standards of ethical business practices and promote awareness of ethical issues that may be encountered in carrying out a director’s, officer’s or employee’s responsibilities. Among other things, the Code of Conduct:

•

clarifies (i) standards and prohibited activities pursuant to the Foreign Corrupt Practices Act, (ii) Gyre’s internal and external disclosure obligations and recordkeeping procedures, (iii) Gyre’s policies with respect to dealings with public officials and (iv) that failure to report a known or suspected violation of the Code of Conduct is itself a violation of the Code of Conduct;

•

updates Gyre’s policies with respect to equal employment opportunity and its whistleblower hotline;

•

updates Gyre’s policies and procedures with respect to an amendment or waiver of the Code of Conduct;

•

includes a commitment to protecting the environment; and

•

makes various other updates, including clarifying, ministerial and conforming changes.

The adoption of the Code of Conduct did not result in any explicit or implicit waiver of any provision of the Original Code of Conduct. The foregoing description is qualified in its entirety by reference to the full text of the Code of Conduct, a copy of which is filed as Exhibit 14.1 to this Form 8-K and incorporated herein by reference.
