Green Star Royalties Acquires 3% Royalty on AI and Data Centre Disruptor Company, Cerio
Star pays $3m for a 3% cerio royalty to support ai data centre efficiency.

Green Star Royalties Ltd., a 45.9% joint venture of Star Royalties Ltd. (STRR), has executed definitive agreements to acquire a 3% gross revenue royalty on Cerio, a private Canadian company specializing in AI and data center infrastructure. The transaction involves consideration of $3 million USD, paid in cash upon execution.
The royalty agreement covers current and future corporate-wide gross revenues over a 10-year term, with payments scheduled quarterly. Defensive mechanisms within the deal include a minimum quarterly revenue guarantee and a buyback option for Cerio. Cerio focuses on composable, fabric-based infrastructure for AI and cloud data centers, claiming to improve energy efficiency by 15–35% and increase hardware utilization from approximately 30% to 80–90%. This transaction expands Green Star's cleantech portfolio into the AI infrastructure energy efficiency niche, providing non-dilutive, immediately revenue-generating assets.
Star Royalties Ltd. (STRR) announced an expected incremental expansion of its portfolio through Green Star Royalties, a move characterized as routine rather than a market-moving surprise. The transaction involves a $3M USD cash outlay, which will be funded through a joint venture structure. This expenditure is manageable given the company’s cash position of approximately $992k and marketable securities totaling around $2.4M.
The investment aligns with Green Star’s stated strategy of monetizing carbon offsets and investing in North American cleantech royalties. The dominant near-term catalyst for the company remains the Summit Royalties merger, which received shareholder approval on June 22, 2026, and is expected to close in Q2 2026. This royalty acquisition does not alter the merger economics or strategic rationale. There is no material deviation from prior guidance or expectations, with the focus remaining on scaling the royalty platform through the upcoming merger.
Star Royalties Ltd. (STRR) operates a diversified portfolio of royalties and streams across Canada, the U.S., and Australia. Its flagship assets include a 4% gold stream on the Copperstone project in Arizona, a 2% minerals royalty on the Keysbrook mine in Australia, and a 45.9% interest in Green Star Royalties, which focuses on cleantech and carbon offsets.
The company is currently undergoing a transformative merger with Summit Royalties Ltd. The transaction will combine 50 royalty and stream assets, creating a pro forma entity with an expected market capitalization of approximately C$184 million and a projected compound annual growth rate (CAGR) of roughly 47% over three years. Management is focused on capital preservation, achieving cost synergies of approximately $2 million annually, and scaling production assets from four to six by 2027.
