Item 1.01. Entry into a Material Definitive Agreement.

On November 20, 2025, Healthcare Triangle, Inc., a Delaware corporation, (the “Company”), entered into a Securities Purchase Agreement (“Purchase Agreement”) with certain institutional investors (the “Investors”). Under the Purchase Agreement, the Company has agreed to issue 20% original issue discount senior unsecured convertible promissory notes (“Notes”) in an aggregate original principal amount of up to $15,000,000, which will be convertible into shares of the Company’s common stock, par value $0.00001 per share (“Common Stock”). The closing of the first tranche was consummated on November 20, 2025, and the Company issued the initial Note for an aggregate original principal amount of $7,500,000 (the “Initial Tranche”). The Note issued in the Initial Tranche was sold to the Investors for a purchase price of $6,000,000, representing an original issue discount of twenty percent (20%), and matures on November 20, 2026. The second Note will be an aggregate original principal amount of $7,500,000 and will be issued after the satisfaction of certain conditions precedent, including the Company having an effective registration statement for the resale of the shares of Common Stock issuable pursuant to the conversion of the Notes. The Company may request that the Investor purchase up to $15 million of additional Notes, which is subject to the approval of the Investors.

The Notes rank senior to all future indebtedness of the Company and pari passu with all other Notes issued under the Purchase Agreement. Any unpaid amount bears interest at the past due rate of 18% per annum. The Notes are convertible at any time after the issuance date at the election of the holder. The conversion price is the greater of (i) eighty percent (80%) of the lowest Closing Price during the five trading days immediately preceding the conversion date and (ii) $0.38 per share. Upon receipt of a conversion notice, the Company must deliver the applicable shares no later than one trading day thereafter. Failure to timely deliver shares results in liquidated damages equal to two percent (2%) of the outstanding principal amount per month until cured. The Notes include customary events of default and provide that upon an uncured Event of Default the Mandatory Default Amount becomes immediately due and payable.

In connection with the Purchase Agreement, on the Company entered into a Registration Rights Agreement (the “RRA”) with the Investors. The RRA requires the Company to file a registration statement covering the resale of at least 300% of the maximum number of Conversion Shares issuable at the Floor Price. The filing deadline is the tenth calendar day after signing, and the effectiveness deadline is 60 days after the Filing Deadline. Failure to meet these deadlines or maintain an effective registration statement results in liquidated damages of 2% per month, up to a maximum of 20%. The Company has also agreed to use commercially reasonable efforts to obtain stockholder approval for the issuance of the shares of Common Stock issuable upon pursuant to the Notes in accordance with Nasdaq Listing Rules.

The Offering resulted in gross proceeds to the Company of approximately $6,000,000, before deducting placement agent fees and commissions and other offering expenses. RBW Capital Partners LLC (a division of Dawson James Securities, Inc.) acted as placement agent for the offering. As compensation for such placement agent services, the Company has agreed to pay RBW, an aggregate cash fee equal to 8.0% of the gross proceeds received by the Company, plus $100,000 for its legal fees and expenses.

The foregoing summaries of the Purchase Agreement, the Notes, and the Registration Rights Agreement are qualified in their entirety by reference to the full text of such agreements, copies of which are filed as Exhibits 10.1, 4.1, and 10.2, respectively, to this Current Report on Form 8-K and are incorporated herein by reference.
