Notice to the Market – Acquisition of CURA – Centro de Ultrassonografia e Radiologia S.A

ALLIANÇA SAÚDE E PARTICIPAÇÕES S.A. (“Company” or “Alliança”) (B3: AALR3), in accordance with Law No. 6,404 of December 15, 1976, as amended, hereby notifies its shareholders and the general market that the acquisition of CURA – Centro de Ultrassonografia e Radiologia S.A. (“CURA”) was completed on August 1, 2025, through the signing of the Closing Agreement.

Between the signing of the agreement and the completion of the transaction, the parties agreed upon relevant adjustments to the acquisition structure. The base price was adjusted to R$ 1.00 (one real), and CURA maintained an outstanding financial debt with the Porto Alegre Medical Mutual Credit and Economy Cooperative (“Unicred Operation”) in the amount of R$ 20,000,000.00, maturing in July 2038, with an annual interest rate of CDI + 2.43%, payable monthly and secured by the assignment of CURA’s receivables amounting to R$ 1,200,000.00 per month. This new structure ensures that the acquisition is supported by the operational cash flow generated by the acquired asset, without altering the contingent price (“Earn-Out”), which is linked to CURA’s Gross Operating Revenue performance.

The assumption of the Unicred Operation has an immaterial effect on Alliança Saúde’s consolidated debt, particularly following Lormont Participações S.A., the Company’s controlling shareholder, acquiring significant financial credit operations of Alliança Saúde and expressing its intention to utilize such credits in the Company’s future capital increase, as disclosed in the Material Fact published on July 30, 2025.

The consummation of CURA’s acquisition occurs at a strategic moment for the Company, characterized by cost optimization, a significant reduction in debt, and an increase in the annual Gross Operating Revenue, thereby enhancing the Company’s operational cash generation.
