Artisan Mid Cap Fund Matt Kamm, Jason White, Jim Hamel, Angela Wu, Jay Warner | “Comfort Systems is a provider of heating, ventilation and air conditioning services. Strong demand from data center construction, driven by hyperscaler customers, now accounts for a majority of its revenue. Recent earnings results exceeded expectations, with year-over-year same-store revenue growth of 51% and margin expansion. It also raised full-year guidance. We view the company as well positioned to benefit from ongoing investment in data center infrastructure and added to the position during the quarter.” | NEUTRAL | Q2 2026 Jul 21, 2026 | View Pitch |
Forager International Shares Fund Steve Johnson | “Comfort Systems appeared in last year's report as a fresh buy out of the April 2025 selloff, and it continued to deliver handsomely this year before we moved on, contributing 1.7% to returns. This mechanical, electrical and HVAC contractor is a prime beneficiary of the surge in data-centre construction and the reshoring of US manufacturing, where demand for large-scale, technically complex systems is growing rapidly. Few competitors can match its national footprint and execution capacity on mission-critical builds, and through the Fund's holding period the order book grew rapidly, margins kept expanding and the balance sheet carried net cash. The business never stopped executing, but the share price ran up hard. Having bought in the panic, we trimmed into strength and then exited in full in February 2026 at around $1,400 a share, up more than threefold in a year, purely because the valuation got too steep. It is a stock we would happily own again at the right price.” | NEUTRAL | Q2 2026 Jul 15, 2026 | View Pitch |
Renaissance Investment Management - Large Cap Growth Renaissance Investment Management | “Comfort Systems USA was another large contributor after reporting solid quarterly operating results. The company delivered an acceleration in organic revenue growth and highlighted attractive incremental margin opportunities. Importantly, management indicated that growth appears sustainable, with backlog growth accelerating and supporting a strong pipeline of future work. BSD Analysis: Comfort Systems USA is a high-quality, high-growth HVAC services oligopolist whose stock is a conviction bet on the non-cyclical, non-discretionary need for building efficiency and maintenance. The core moat is its massive, integrated network of over 45 operating companies across the United States, providing mechanical, electrical, modular, and plumbing systems. This service-oriented model provides a stable, recurring revenue stream. The company is actively compounding its value, recently increasing its quarterly dividend. Comfort Systems USA is a disciplined industrial compounder, focused on consistent, profitable growth through a combination of organic expansion and strategic acquisitions.” | BULL | Q2 2025 Jun 30, 2025 | View Pitch |
Forager International Shares Fund Steve Johnson | “After sitting on the watchlist for years, the April market selloff gave us the chance to buy Comfort Systems USA (NYSE:FIX) at an attractive price. It provides mechanical and heating, ventilation and air conditioning (HVAC) services across industrial and institutional markets. Comfort is especially well-positioned to benefit from the surge in data centre construction, where demand for large-scale, technically complex HVAC systems is growing rapidly. Few players have the national footprint, project expertise and local execution capacity that Comfort offers, making it a go-to contractor for mission-critical infrastructure builds. Since the April 2025 low, the share price has already risen about 80%, contributing 1.5% to Fund returns. While significant profits have been taken, Comfort Systems remains a high-quality operator in a structurally growing market, and a strong example of disciplined watchlist management paying off. BSD Analysis: Comfort's core HVAC contracting business is gaining from secular trends in data center buildout, reshoring of manufacturing, and upgrades to energy-efficient systems. The company has historically generated solid returns on capital, supported by a disciplined acquisition strategy and strong project execution. With a robust backlog and growing mix of complex, higher-margin projects, earnings visibility has improved despite the cyclical nature of construction. The stock's sharp rebound reflects improved expectations, but valuation remains reasonable versus its growth and margin profile. Key risks include project-cycle volatility and execution on large data center work, but the franchise's scale and reputation offer a durable edge.” | BULL | Q2 2025 Jun 30, 2025 | View Pitch |
