Strategic Partnership Will Drive Sustainable Oxygenation Solutions in Key International Markets

SANTIAGO—Oxzo, a global leader in oxygenation services for aquaculture, today announced a strategic investment of US$25 million led by S2G Investments (“S2G”), a multi-stage investment firm focused on scaling solutions across the energy, food & agriculture, and oceans sectors. This significant partnership, which builds on previously secured investments from Fiordo Austral and Altis, marks a crucial step in Oxzo’s growth trajectory, positioning the company for substantial international expansion.

Oxzo, based in southern Chile, has developed patented technology in oxygenation and aeration systems, establishing itself as a strategic partner to the global aquaculture industry. Its solutions, which include fully automated systems for producing oxygen, air, and ozone, directly enhance productivity, animal welfare, and environmental sustainability in both sea and land-based operations. Advanced systems like the Oxymar automated pontoons and Oxymovil mobile oxygen generation units are designed to increase production efficiency and reduce fish mortality.

The impact of Oxzo's technology is already evident:

• Chile: Solutions deployed for salmon farmers have led to biomass increases of 5 to 10 percent, cost reductions of up to 5 percent, and more than 24 percent lower fish mortality, according to independent industry data.

• Norway: The company is working with three of Norway’s leading, globally recognized salmon producers, contributing to improved animal welfare and addressing major health challenges like sea lice proliferation by reducing fish stress and mortality.

• Canada: Oxzo's systems support the industry's adaptation to new regulatory standards, offering an efficient and sustainable alternative to options like land-based grow-out facilities, thereby fostering sustainable aquaculture growth.

"At S2G, we see aquaculture as a cornerstone of the global protein system, one that must evolve to meet rising demand while protecting ocean ecosystems," said Larsen Mettler, managing director of S2G’s Oceans Investment team. "Oxzo’s innovations in oxygenation and aeration directly advance that goal by improving productivity, fish welfare, and aquatic environments at scale. We believe its solutions are becoming foundational to the industry’s ability to operate efficiently and sustainably, and we are delighted to partner with Oxzo’s management team."

Rafael Ariztia, chairman of Fiordo Austral and Oxzo, expressed his enthusiasm: "We are proud to welcome S2G as an investment partner. Their participation aligns perfectly with Oxzo’s strategy to grow in international markets and represents a great opportunity, granting access to highly qualified teams, top-level information, and global networks."

Claudio Inglesi, partner at Altis, added, "S2G brings deep sector experience and a proven record in ocean investment. This partnership reinforces the positive outlook for oxygenation in aquaculture as a lever for productivity and animal welfare, and will accelerate the international expansion of Oxzo as it consolidates as a strategic partner for the industry."

With approximately US$2.5 billion in committed capital, S2G has invested in more than 100 companies across five continents. This partnership with Oxzo is the firm’s second investment in a Latin American company, underscoring its commitment to advancing a prosperous and resilient blue economy. The investment will strengthen Oxzo's purpose of expanding Chilean innovation in aquaculture oxygenation into new markets, driving a more efficient, responsible, and sustainable global industry.
