par value financial

"an amount equal to the par value of the cancelled shares"

Par value is the fixed amount printed on a bond or stock that represents its original value when issued. It’s like the face value of a coin or bill—what the issuer promises to pay back or the starting price of a stock—though it often doesn’t change with market prices. It matters because it helps determine certain financial details, like how much the company will pay back at maturity.

share capital reduction financial

"registration of the share capital reduction with the Public Registry"

A share capital reduction is a legal change that lowers a company's recorded equity by cancelling shares, cutting the nominal value of shares, or returning money to shareholders. Think of it like removing or shrinking slices of a pie: it changes the number or stated size of shares outstanding and alters per-share figures and ownership percentages. It matters to investors because it affects balance-sheet metrics, voting stakes, and how earnings or assets are spread across remaining shares, and typically requires formal approvals.

Ref.: Relevant Event

I am pleased to address you in my capacity as Head of Market Relations of Central Puerto S.A. (the "Company"), in order to inform you that: (i) within the framework of the treasury share repurchase plan approved by the Company on August 24, 2023, and (ii) pursuant to the provisions of Article 67 of the Capital Markets Law No. 26,831, the cancellation by operation of law of 2,299,993 common shares, each carrying one vote per share, has taken place.

Such cancellation is due to the fact that, upon the lapse of three (3) years from their acquisition (made between September 8, 2023 and October 11, 2023), the aforementioned treasury shares remained in the Company's portfolio without having been disposed of, and without any shareholders' meeting resolution having been adopted regarding their destination, as required by applicable regulations.

Accordingly, the Company's share capital is reduced by operation of law by an amount equal to the par value of the cancelled shares, bringing the new share capital to ARS 1,511,470,229, represented by 1,511,470,229 common shares entitled to one (1) vote per share, with a par value of ARS 1 each.

In light of the foregoing, the Company's Board of Directors has resolved to proceed with the registration of the share capital reduction with the Public Registry.

Yours sincerely,
