Private Placement and Purchase Agreement

On June 24, 2025, Titan Pharmaceuticals, Inc. (the “Company”) entered into a Securities Purchase Agreement (the “Purchase Agreement”) with Blue Harbour Asset Management L.L.C-FZ (the “Investor”), pursuant to which the Company has agreed to issue 60,000 shares of Series C Convertible Preferred Stock, par value $0.001 per share (the “Series C Preferred Stock”) to the Investor at a price of $10.00 per share, for an aggregate purchase price of $600,000 (the “Private Placement”). The terms, rights, obligations and preferences of the Series C Preferred Stock are set forth in a Certificate of Designations, Preferences and Rights of Series C Convertible Preferred Stock of the Company (the “Certificate of Designations”), filed with the Secretary of State of the State of Delaware on June 24, 2025. Copies of the form of Purchase Agreement and the Certificate of Designations are attached hereto as Exhibits 10.1 and 4.1, respectively, and are incorporated herein by reference. On June 27, 2025, the Company issued a press release announcing that it completed the Private Placement. A copy of the press release is furnished herewith as Exhibit 99.1.

Under the Certificate of Designations, each share of Series C Preferred Stock will be convertible, at the holder’s option at any time, into shares of the Company’s common stock at a conversion rate equal to the quotient of (i) the stated value of such share divided by (ii) the initial conversion price of $3.40, subject to specified adjustments as set forth in the Certificate of Designations. Based on the initial conversion rate, approximately 176,471 shares of the Company’s common stock would be issuable upon conversion of all the shares of Series C Preferred Stock, when issued, assuming the absence of in-kind dividends. The Series C Preferred Stock will contain limitations that prevent the Investor from acquiring the lower of either (i) the maximum percentage of common stock permissible under the rules and regulations of The Nasdaq Stock Market (“Nasdaq”) without first obtaining shareholder approval or (ii) 19.99% of the Company’s outstanding common stock.

The holder of the Series C Preferred Stock is entitled to receive dividends on shares of the Series C Preferred Stock equal (on an as-if-converted-to-common-stock basis) to and in the same form as dividends actually paid on shares of the common stock. No other dividends will be paid on shares of the Series C Preferred Stock. Any shares of Series C Preferred Stock may, at the option of the holder, be converted at any time into that number of shares of common stock at the conversion price set forth above. Without approval of holders of a majority of the outstanding Series C Preferred Stock, the Company may not (a) alter or adversely change the powers, preferences or rights given to the Series C Preferred Stock, (b) amend its certificate of incorporation or other charter documents in any manner that adversely affects any rights of the holders of the Series C Preferred Stock, (c) increase the number of authorized shares of the Series C Preferred Stock, (d) enter into or consummate any Fundamental Transaction (as defined in the Certificate of Designations), or (e) enter into any agreement with respect to any of the foregoing. In the event of any liquidation, dissolution or winding up of the Company, the holder of the Series C Preferred Stock will be entitled to receive out of the assets, whether capital or surplus, of the Company the same amount that a holder of common stock would receive if the Series C Preferred Stock were fully converted to common stock, which amounts shall be paid pari passu with all holders of common stock. The foregoing description provides a summary of certain material terms of the Series C Preferred Stock issued pursuant to the Purchase Agreement, as set forth in Certificate of Designations, which is filed as Exhibit 4.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The shares sold in the Private Placement do not involve a public offering and have not been registered under the Securities Act of 1933, as amended, in reliance on Regulation S thereunder.

Registration Rights Agreement

In connection with the Private Placement, the Company entered into a registration rights agreement with the Investor (the “Registration Rights Agreement”) pursuant to which the Company has agreed to provide certain registration rights upon the occurrence of certain events set forth in the Registration Rights Agreement. The foregoing description of the Registration Rights Agreement does not purport to be complete and is qualified in its entirety by the full text of the Registration Rights Agreement, which is filed as Exhibit 10.2 to this Current Report on Form 8-K and is incorporated herein by reference.
