|---|---|---|
Benedikt Baumann's Primary Research Fund returned 1.2% since inception in December 2025, focusing on super-durable businesses with sustainable competitive advantages. The fund added SOL Group, a dual-engine Italian industrial compounder combining Europe's leading industrial gas franchise serving 50k customers across 32 countries with Vivisol, the largest home respiratory care provider serving 750k patients. SOL's industrial gas business creates regional oligopolies through expensive logistics and infrastructure that took nearly a century to build, while Vivisol benefits from Europe's aging population and healthcare systems shifting chronic care from hospitals to homes. The manager emphasizes businesses designed to last like Roman aqueducts, particularly those unlikely to be negatively affected by AI over decades. Key risks include AI disruption to software businesses, cyclical industrial gas volumes, and healthcare reimbursement pressure. The strategy prioritizes quality, duration, and conviction over traditional valuation multiples, seeking businesses that can compound for 10+ years where business quality dominates entry valuation concerns.
The Primary Research Fund invests in a dozen super-durable, quality businesses with sustainable competitive advantages, excellent management, and reasonable valuations, focusing on companies designed to last like Roman aqueducts that can compound for decades without being negatively affected by technological disruption like AI.
The manager remains confident in the durability of the fund's carefully selected businesses, emphasizing long-term compounding with a focus north. He commits to continued primary research, asking inconvenient questions, and allocating capital behind businesses built to last.

AIThe extended federal government shutdown added volatility during what was otherwise a risk-on environment, with a mid-quarter shift in market behavior for AI-related equities as the exuberant narrative evolved to one more balanced in assessing the technology's enormous potential against staggering capital spending plans and high expectations. The team initiated a position in Credo Technology as a more diversified way to gain exposure to strong trends in AI-connectivity. |

Home HealthVivisol has grown from 140k patients in 2010 to 750k by 2024, representing 13% compound annual growth driven by Europe's aging population and healthcare systems moving chronic care from hospitals to patients' homes.

| TICKER | COMMENTARY |
|---|---|
| AHT.L | After receiving multiple requests, I'm doing my best to convince Alan Pirie, CEO of our offshore rental business Ashtead Tech, to join us this year. Alan is a powerhouse of a CEO, and I hope to report back with some good news on his attendance. |
| AI.PA | Air Liquide, one of our larger holdings in the portfolio, experienced downward market pressure. We trimmed our position over the last few months based on valuation yet view the company's strategic positioning in decarbonization and ongoing contract wins supporting durable earnings potential. |
| LIN | While the company remains a high-quality global leader in industrial gases, shares of Linde plc declined nearly 10% in Q4 due to a persistent industrial gas volume recession, softer guidance and global macroeconomic concerns. From a macro standpoint, the company continues to struggle with negative base volumes in its core industrial segments. |
| SOL.MI | Founded in 1927 in Monza, Italy, SOL emerged as a dual-engine industrial compounder with close to €2bn in sales. They operate both, one of Europe's leading industrial gas franchises serving 50k customers across 32 countries (think Linde or Air Liquide), as well as a homecare health business (called Vivisol) that has grown to 750k patients, making it the largest home respiratory care provider in Italy, Belgium, and the Netherlands. |
| WIT.MI | We had partners flying in from Berlin, Brussels, London, Luxembourg, Milan, and some who simply walked. It's been wonderful to see relationships built across the room and share a productive day together with the management of our data center business, WIIT. Live and in action is always best! A sincere mille grazie to Enrico Rampin and Christoph Herrnkind from WIIT for the revealing fireside chat and for leaning into all our questions. What a great opportunity to gain fresh business insights, remind them to keep raising prices and share why they deserve their spot in the fund. |
