Southland Holdings, Inc.

Item 1.01 Entry into a Material Definitive Agreement. As previously reported, Southland Holdings, Inc., a Delaware corporation (the “Company”) entered into a financial assistance agreement (the “Financial Assistance Agreement”), which governs the terms on which certain sureties of the Company (each, a “Surety,” and collectively, the “Sureties”) have provided, and may continue to provide in the future, financing assistance in respect of bonded construction contracts and projects. Under the terms of the Financial Assistance Agreement, any Surety or Sureties providing financing that is not providing bonds shall be deemed to be providing “Non-Bonding Financing.” The Financial Assistance Agreement provides for, among other things, conversion of certain Non-Bonding Financing into senior non-voting preferred shares (the “Preferred Shares”) in accordance with the terms of a Preferred Shares Term Sheet attached to the Financial Assistance Agreement. On September 30, 2026, the Company and certain other related entities, certain individual shareholder indemnitors, the Sureties, and Berkshire Hathaway Specialty Insurance Company, as collateral agent, entered into the first amendment to the Financial Assistance Agreement (the “First Amendment”). Prior to giving effect to the First Amendment, the Preferred Shares were required to be issued no later than September 30, 2026. Under the terms of the First Amendment, the date by which the Preferred Shares are required to be issued has been extended to be no later than November 13, 2026. The foregoing description of the First Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the First Amendment, a copy of which will be filed as an exhibit to this Current Report on Form 8-K.
