How Aguas Andinas Finances a Non-Discretionary CLP $149,000 Million Annual Capital Programme
By Robert C. Brears · May 11, 2026
Managing the gap between revenue growth and escalating capital obligation is the defining financial challenge of the water sector. Aguas Andinas has bridged this gap by shifting capital deployment from a strategic choice to a regulatory compliance requirement mandated by the Superintendency of Sanitary Services.
In May 2024, the utility secured CHF 100 million on the Swiss market at a rate of 2.0975%. This pricing, sub-3%, is a direct result of their Fitch AA+ rating, proving that institutional investors value regulatory transparency even in climate-stressed regions.
The 30% Equity Retention Model
The 70/30 profit split—ratified in April 2025—forces shareholders to co-invest in infrastructure. This reduces the need for aggressive leverage, maintaining the credit profile necessary for low-cost international debt.

Why the Swiss market for Chilean water debt?
Swiss investors prioritize long-duration, highly regulated assets. The placement diversifies funding and confirms that international liquidity is available for climate-adaptation projects at favorable spreads.
How does EBITDA outpace revenue growth?
By achieving a 2.2% EBITDA growth against <1% revenue growth, the utility demonstrates operational efficiency as the primary engine for capital funding, rather than relying solely on consumer tariff hikes.
