Central Puerto S.A. (NYSE:CEPU) filed a Form 6-K reporting that it and its subsidiary Proener S.A.U. bought back shares on September 28, 2026. The company repurchased 100,000 ordinary shares on the Buenos Aires exchange, known as BYMA, while Proener bought 20,000 American depositary receipts on the New York Stock Exchange.

Both purchases settled on September 29, 2026. Central Puerto is an Argentine electric services company, and its ordinary shares trade in Buenos Aires while its ADRs trade in New York.

The Two Purchases

For the parent company, the 6-K reports an average price of 1,998.67 Argentine pesos per share for the 100,000 shares acquired on BYMA, for a total investment of AR$199,867,084. The trade date was September 28, 2026 and settlement followed on September 29.

For the subsidiary, the report says Proener S.A.U. acquired 20,000 ADRs on the NYSE at an average price of US$12.23 per ADR, for a total of US$244,795.20. It also carries a trade date of September 28 and a settlement date of September 29.

The Compliance Statement

The 6-K refers to Article 64 et seq. of Argentina's Capital Markets Law No. 26,831, which is the legal reference the company cites for these disclosures. It also states that the combined acquisitions by the two entities did not exceed 25% of the average daily trading volume over the preceding 90 business days. That is a volume limit the company reports it observed when buying, and it applies to the total of the parent's and the subsidiary's purchases rather than to each separately.

The document is brief and was signed on September 28, 2026 by Leonardo Marinaro, described as Attorney-in-Fact and Head of Market Relations. It is filed for the month of September 2026 under Commission File Number 001-38376.

Central Puerto's Buyback Reports and Volume Limits

Because this report covers trades for a single day, September 28, 2026, further purchases would be expected to be reported in additional filings if the program continues, although this filing does not say how often that will happen. The items to look for in later reports are the dates, quantities and average prices of any further purchases by Central Puerto and Proener, and any update to the program's terms or limits. The filing itself sets no deadline, approval requirement or future event.
