A2A stock (IT0001233417) closed at €2.301 on August 12, 2026, with 1,841,780 shares changing hands and the latest after-hours snapshot showing €2.305 at 20:09. The companys investor hub says share capital stood at 1,629 million euros and 3,132,905,277 shares at December 31, 2025.

What the latest filing shows

A2As investor hub describes the group as a Life Company focused on essential infrastructure, circular economy models and the energy transition, with a solid financial structure supporting long-term value creation. That framing matters because A2A remains an integrated utilities business rather than a single-asset play.

The same investor page gives a concrete capital base: 3,132,905,277 shares outstanding at December 31, 2025. It also confirms 1,629 million euros of share capital at that date, which helps frame the stock against the companys equity structure rather than only a daily quote.

Price and market context

The stock finished August 12, 2026 at €2.301, and the after-hours reference on August 13, 2026 marked €2.305. That narrow spread suggests the latest session was orderly rather than volatile.

On the same quote page, the listed volume of 1,841,780 shares gives a readable gauge of trading interest for the session. The comparison point is simple: the after-hours reference was just €0.004 above the prior close.

Business model

A2As core business is infrastructure and integrated services tied to decarbonization, territorial services and circular-economy activity. For investors, the key question is whether that mix keeps producing stable cash generation while the group keeps funding transition-related assets.

The companys own language emphasizes sustainable long-term value creation through capital-market access and efficient financing. That is a relevant detail for a utility group because financing structure can matter as much as operating growth.

Closing level

A2A stock was quoted at €2.305 in the latest after-hours view on August 13, 2026, after a regular-session close of €2.301 on August 12, 2026. The market value read sits alongside a share count of 3,132,905,277 at December 31, 2025.
