Argentina has formally launched the AYSA privatization tender, putting a 51% controlling stake in the nation’s largest water and sanitation utility up for grabs. The government expects the sale of Agua y Saneamientos Argentinos to bring in roughly US$500 million.
How the AYSA Privatization Tender Works
The tender is managed on the CONTRAT.AR platform, Argentina’s official digital procurement portal, by the Agency for the Transformation of Public Companies. Interested operators must submit economic offers by 09:59 on August 27, 2026, with envelopes opened publicly at 10:00 the same day.
The winning strategic operator will buy a 51% stake and secure a 30-year concession, extendable by one additional decade. Tariff reviews are scheduled every five years under the model contract approved in April 2026, giving investors a predictable regulatory roadmap.
What the Sale Structure Looks Like
After the 51% block goes to a private operator, another 39% of shares will be sold through an Initial Public Offering on local stock markets. The remaining 10% stays with employees via a shared ownership program, known locally as the Programa de Propiedad Participada.
President Javier Milei’s administration set this structure under Decree 494/25 and Law 27,742, the sweeping reform bill that declared AySA subject to privatization. Economy Minister Luis Caputo oversees the process, which targets closing the sale by early 2027.

Why the Government is Selling AySA
Officials argue the state cannot finance the massive infrastructure upgrades needed for water and sanitation across Buenos Aires and its sprawling suburbs. AySA has absorbed roughly US$2.6 billion (AR$13.4 billion) in subsidies since its 2006 reorganization, a figure that weighs heavily on Argentina’s strained public finances.
Because of this financial burden, the government believes private capital will improve service efficiency and unlock investment the public sector simply cannot afford. Presidential Spokesperson Manuel Adorni confirmed the goal is to transfer 90% of shares to private hands, reserving only a symbolic stake for workers.
Opposition and Legal Concerns
The unified water union, which manages the employee share program, strongly opposes the move. Critics fear job losses, tariff hikes, and the loss of public control over essential services that millions of families depend on daily.
Meanwhile, civil society groups label the sale a violation of the human right to water, arguing that a vital resource should not be treated as a commodity. Legal challenges also target new rules allowing service cuts for non-payment, which opponents call punitive and a threat to low-income households.
What This Means for Expats and Investors
For foreign investors, the AYSA privatization represents one of Argentina’s largest infrastructure opportunities in years, with a clear 30-year concession and built-in tariff adjustment mechanisms. The tender is open to both national and international operators, signaling the government’s desire for global expertise and deep-pocketed bidders.
Expats living in Buenos Aires and surrounding areas should monitor the transition closely, as a private operator may bring service improvements but also potential rate restructuring. The five-year tariff review cycle offers some predictability, though Argentina’s history of economic volatility means currency risk remains a key factor for anyone doing business here.
What Happens Next
Interested parties have until August 12, 2026, to submit questions about the tender documents, giving them a final window to clarify terms before the binding offer deadline. After the August 27 bid submission, the government will evaluate economic offers and expects to announce the winning operator by late 2026 or early 2027.
Once the strategic partner is selected, attention will shift to the IPO of the remaining 39% stake on Argentina’s local stock exchanges. The entire process is designed to move quickly, reflecting the Milei administration’s broader push to shrink the state and attract foreign capital across multiple sectors.
