Stack Capital reports all amounts in Canadian Dollars unless otherwise stated. FINANCIAL SUMMARY Book Value per Share (BVpS): $20.25, compared to $16.57 as at March 31, 2026 (+22% increase)Total Book Value: $313 million The quarter reflected meaningful value creation across the portfolio, led by SpaceX, Fluidstack, CoreWeave and X-Energy. PORTFOLIO COMPANY HIGHLIGHTS SpaceX completed its record-setting initial public offering and began trading on Nasdaq under the ticker SPCX. The offering was priced at US$135 per share, raising US$75 billion at an approximately US$1.77 trillion valuation, and significantly contributed to Stack Capital's Book Value growth. Project Prometheus Stack Capital invested in Project Prometheus, a physical AI company led by Jeff Bezos. The company is developing AI systems that learn from real-world experimentation to accelerate the design, engineering and manufacturing of physical products across industries including computing, aerospace and automotive. Project Prometheus raised US$12 billion at a US$41 billion valuation. Fluidstack Stack Capital invested US$12.0 million in Fluidstack, a next-generation data centre operator and AI infrastructure provider. Anthropic selected Fluidstack to deliver custom-built data centres in New York and Texas as part of its US$50 billion investment in American AI infrastructure. Following Stack Capital's investment, the carrying value of the Company's Fluidstack position increased by approximately 90%. Crusoe announced that it had contracted 4.9 gigawatts of AI infrastructure capacity across its data centre projects and Crusoe Cloud platform. Crusoe's broader development pipeline, including contracted projects, sites under active tenant negotiation and sites in advanced development, now exceeds 40 gigawatts, reflecting significant demand for large-scale AI infrastructure. X-Energy completed its initial public offering during the quarter, raising approximately US$1.1 billion in net proceeds, and began trading on Nasdaq under the ticker XE. We continue to believe X-Energy is well positioned to benefit from the growing demand for advanced nuclear power as AI, electrification, and energy security drive long-term electricity demand. Hopper went live with RBC, marking a significant enterprise milestone and validating the strength of its B2B travel and fintech solutions, which now power travel platforms for several of the world's leading financial institutions. Databricks Subsequent to quarter-end, Databricks signed a term sheet for a strategic financing at a US$188 billion valuation, expected to close later this summer.

MANAGEMENT COMMENTARY "Q2 was a strong quarter for Stack Capital, with Book Value per Share increasing 22% to $20.25," said Jeff Parks, CEO of Stack Capital. "Our portfolio companies continue to execute and make meaningful progress, with several completing or pursuing financings at higher valuations and others achieving important operational milestones. While broader markets have experienced periods of volatility, we remain focused on long-term value creation and believe short-term market movements do not alter the long-term growth prospects of these high-quality businesses. Following our $40 million capital raise, we are well-positioned to pursue new opportunities and believe 2026 can be a meaningful year for Book Value growth and portfolio monetization."

Fluidstack raised $830M Series A at a $7.5B valuation. Led by Situational Awareness, the round backs our mission to be the fastest on the planet at deploying hundreds of gigawatts of compute for the world's leading AI labs. We believe whoever deploys frontier infrastructure fastest will shape whether AI expands human freedom. We're hiring.

Fluidstack has raised $830 million in a Series A funding round at a $7.5 billion valuation. The round, which closed in January, was led by Situational Awareness, the AI-focused investment firm founded by former OpenAI researcher Leopold Aschenbrenner. The AI infrastructure startup will use the capital to expand its global data centre operations. Fluidstack acquires power, designs and constructs data centres, and operates computing infrastructure for AI labs. The company claims it can deliver gigawatts of capacity within six months, compared with the industry standard of 18 to 24 months. Fluidstack's largest project is a partnership with Anthropic to build $50 billion of computing infrastructure across the United States. Initial facilities are being developed in Texas and New York, with sites expected to come online throughout 2026.
