What Happened?
Comfort Systems USA stock has surged about 80% over the past six months, recently trading near $1,384 per share, as investors increasingly view the company as a major beneficiary of the rapid expansion of artificial intelligence data centers and large industrial construction projects across the United States.
The rally has been driven primarily by strong earnings results and accelerating demand for technology infrastructure construction, which confirmed that the company is capturing a growing share of data center-related work.
Comfort Systems installs mechanical, electrical, and HVAC systems that manage cooling, airflow, and power infrastructure inside complex facilities such as data centers, semiconductor fabrication plants, and advanced manufacturing sites.
The company recently reported earnings per share of $9.37 and revenue of about $2.6 billion, up roughly 42% year over year, while backlog reached a record $11.9 billion, signaling continued demand from large technology and industrial customers.
Management reinforced that strength during the latest earnings call. CEO Brian Lane said the company delivered “record earnings and backlog,” while management noted technology projects, largely tied to data center construction, represented 45% of revenue in 2025, up from 33% the prior year as investment in AI infrastructure accelerates.
Investor positioning has also shifted alongside the rally. Barclays PLC increased its stake by about 97% to roughly 64,700 shares worth about $53 million, while First Trust Advisors raised its position by about 30% to more than 513,000 shares valued around $424 million.
Some insiders trimmed holdings following the run-up, with Director Darcy Anderson selling 4,500 shares for about $6.2 million and SVP Terrence Reed selling roughly 1,100 shares for about $1.6 million.
Comfort Systems operates in a competitive engineering and construction services market that includes firms such as EMCOR Group and Quanta Services, which also benefit from rising investment in data centers and industrial infrastructure.

Comfort Systems has become an important contractor supporting the rapid expansion of data centers and advanced industrial facilities across the United States.
These projects require specialized mechanical and electrical systems to manage cooling, airflow, and power distribution, which are essential for operating modern AI data centers.

Analyst forecasts suggest revenue could grow from about $9 billion in 2025 to roughly $19 billion by 2030, reflecting continued investment in AI infrastructure, semiconductor manufacturing, and advanced industrial construction.
Margins have also improved as the company executes larger and more complex projects while expanding its modular construction capabilities, which allow building components to be manufactured off-site and installed more efficiently.
Based on these inputs, the model estimates a target price of $1,695, implying about 22% total upside over the next few years, suggesting the stock appears slightly undervalued at current prices.
Over the next year, performance will likely depend on continued expansion in data center construction, semiconductor manufacturing investment, and other large industrial infrastructure projects, all of which require the mechanical and electrical systems where Comfort Systems has developed deep expertise.
