RE: Relevant information – Cancellation of Class B Treasury Shares
Buenos Aires, December 30, 2025 – Grupo Supervielle S.A. (NYSE: SUPV; BYMA: SUPV), (“Supervielle” or the “Company”) a domestic universal financial services group in Argentina with a nationwide presence, informs that, on December 30, 2025, the Company’s Board of Directors acknowledged that, pursuant to the provisions of Article 67 of Capital Markets Law No. 26,831 (as amended), between November 25, 2025, and December 30, 2025, 2,422,403 Class B common shares, each carrying one vote per share, were automatically cancelled.
Such cancellation took place as a consequence of the expiration of the three (3) year term from the date of acquisition carried out between November 25 and December 30, 2022, the aforementioned treasury shares remained in the Company’s portfolio without being disposed of, as required under applicable regulations.
As a result of this automatic cancellation mentioned, and in accordance with the applicable regulations, the share capital of Grupo Supervielle has been automatically reduced by an amount equivalent to the nominal value of the cancelled shares. As a result of that, as of December 30, 2025, the new share capital amounted to Ps. 444,411,711, consisting of 61,738,188 Class A shares and 382,673,523 Class B shares.
Yours faithfully,
