White Brook Capital's Q1 2026 commentary highlights a challenging macro environment with higher inflation, oil prices, and debt costs following U.S. military action against Iran. The manager believes oil price normalization will take longer than markets expect, leading to delayed Federal Reserve rate cuts. AI continues advancing but employment impacts remain uncertain, with significant gaps between marketing claims and actual capabilities ahead of major IPOs. The portfolio focuses on undervalued small-cap opportunities, particularly in healthcare. Key holdings include ICON, a contract drug manufacturer trading at low multiples after a minor revenue restatement caused a 40% stock decline; Perma-Fix Environmental, positioned for nuclear waste disposal growth; S&P Global, purchased during an AI-driven sell-off; and two healthcare companies with conservative guidance the manager expects to be revised upward. The manager anticipates meaningful performance contributions beginning in Q2, with significant progress by Q3, despite the more challenging operating environment for companies generally.
White Brook Capital focuses on undervalued small-cap companies with strong fundamentals trading at significant discounts to intrinsic value, particularly in healthcare and specialized industrial sectors where conservative guidance masks underlying growth potential.

| TICKER | COMMENTARY |
|---|---|
| ICLR | Icon Public Limited Company is a global contract drug manufacturing company we've followed for some time but was always too well priced to own. In February, the company disclosed an internal investigation into revenue recognition that would impact revenue by less than 2%. The stock fell 40%. We like the fundamentals of the contract drug manufacturing industry and ICON's record $24+ billion backlog. We don't believe the restatement should impact their margin opportunity, their existing contracts, or their ability to win new business and anticipate a significant rally after their formal restatement filing. We believe the company trades at a low double digit multiple of free cash flow, a fraction of its historical average and a price that materially underestimates the strength of their business. |
| PESI | Perma-Fix Environmental is a hazardous waste disposal company in the early days of a J-curve in revenue growth. Their most significant near term opportunity is the disposal of nuclear waste at their Hanford plant. This $200 million market capitalization company with $60 million in revenue will add $1-2 million per month in revenue to grout low activity nuclear waste in the next year as the disposal ramps to at least $70 million per year for the next 10 years. Additionally, there is an additional opportunity to earn a piece of an additional $4 billion in work currently being evaluated and awarded by the Department of Energy where Perma-Fix has the only regional facility to support the contract. |
| SPGI | S&P Global is one of the financial market's greatest toll businesses. White Brook bought a position during the first quarter when one of the quarter's AI driven market sell-offs drove the price from >$550 to ~$380 on the speculation that artificial intelligence will destroy its moat. In reality growth and tumult in private credit, data center financing, and AI driven financial engineering products reinforce the necessity of the company's services as a provider of ratings, analytics, and insight. We believe the company is a rare combination of defensive resilience and high-growth potential and are thrilled by the price that we were able to buy it. |
| SMTI | Sanara Medtech continues to be an extremely favorable risk reward. On their fourth quarter call they offered revenue guidance of 13-17% growth in line with sell side expectations but below the 20% some hoped for. At their valuation, we believe the forecasted growth to be more than good enough and likely to be revised upward. With increasing evidence of their product's efficacy recently released and a focus on increasing per hospital doctor penetration, we continue to believe that there is significant room for sustained growth rate acceleration. |
| RPID | Rapid Micro Biosystems also continues to be an extremely favorable risk reward. On their fourth quarter call, similar to last year, they also offered underwhelming guidance. We believe guidance to be conservative given increasing business momentum with significant early rollouts with Amgen, Samsung Biologics, and Merck Millipore - all of which have capacity and are likely to place large follow-on orders. We believe management is exceptionally conservative, the company is well positioned, and the company represents the best risk reward in the portfolio. |
