Absolutely, Alex. Before we get started though, I need to mention that this podcast is AI-generated content for educational and entertainment purposes only.

The headline numbers are just incredible, Alex. Same-store revenue growth of 35% for Q4, and they hit a quarterly gross margin above 25% for the first time in company history. Earnings per share came in at $9.37, which is a 129% increase from last year.

This is where it gets really interesting, Alex. The company is heavily tied to data center construction, which now represents 45% of their revenue, up from 33% the prior year. But here's the key insight from CEO Brian Lane - they're what he calls a "late-cycle participant."

It means when you see those big hyperscaler CapEx announcements from companies like Microsoft or Amazon, Comfort Systems won't see that work show up in their backlog for another year or two. The backlog they're booking today reflects projects that were planned one to two and a half years ago. So they're essentially working on yesterday's AI boom announcements while today's announcements will hit their revenue in 2027 and 2028.

Exactly. Modular was 18% of their revenue, and more than half of their sequential backlog increase in Q4 was from new modular bookings. They're expanding capacity from 3 million to 4 million square feet by the end of 2026, and here's the kicker - this expansion is primarily driven by demand from their two largest hyperscaler clients.

It really is. And the economics are compelling too. The company is now generating over $1.2 billion in operating cash flow, and they're being very disciplined about capital allocation. They returned over $200 million to shareholders through buybacks and increased their dividend by almost 50%.

That was actually one of the most interesting parts of the Q&A, Alex. CEO Brian Lane was very frank about this. They're using what he calls an "all-of-the-above approach" to hiring, including their contract craft professional divisions like Kodiak and Pivot that provide traveling workers. But he emphasized something crucial - they're being extremely disciplined about not overcommitting to projects.

Lane said they go through detailed processes to map out labor projections before taking on new work - when projects will start, who will be available, how many people they'll need. He made it clear that being good to their workforce is more important than optimizing spreadsheets, because "the spreadsheet is no good if the people are not there."

They're expecting mid-to-high teens same-store revenue growth for 2026, weighted more heavily to the first half. But CFO Bill George explained this is more about easier comparisons in the first half rather than actual growth acceleration. The company had a steep ramp-up in the second half of 2025, making those comparisons tougher.

Great question. George addressed this directly - they don't quote equipment without getting quotes from suppliers first, and customers are actually releasing them to purchase materials very early in the process, sometimes before work even hits backlog. For labor costs, where they take the real risk, they rely on their expertise in pricing jobs appropriately to handle wage inflation over time.

This was one of my favorite parts of the call, Alex. George was brutally honest - their cash flow is "relentless" and outpacing their ability to deploy it through M&A. They're being very selective, paying more for companies than ever before, but only because skilled electrical contractors with experienced teams are worth more than in the past.

Exactly. George said they'll choose "conviction over making spreadsheets happy" when it comes to acquisitions. They want companies that are good peers to their existing operations, particularly those with decades of data center experience.

Look, Comfort Systems is essentially a leveraged play on AI infrastructure spending, but with a 1-2 year lag. They have the specialized skills, the customer relationships, and now the manufacturing capacity to capitalize on this megatrend. The margins are expanding, cash generation is incredible, and they're being disciplined about growth.

Absolutely. And with 67% of revenue coming from industrial clients, mostly data centers, there's definitely concentration risk. But given the structural shift toward AI and the need for massive computing infrastructure, this looks like a multi-year tailwind.
