Extreme heatwaves are putting power grids, data centers, and hospital systems under pressure, and that is pulling attention toward companies that help keep critical infrastructure running when temperatures spike. This article looks at how the latest heat related disruptions connect to a focused Climate Resilience Infrastructure Providers screener, and why some investors are watching this theme more closely. The goal is not to chase headlines, but to understand which business models may benefit from rising demand for cooling, ventilation, and grid equipment. Below, you will see 3 stocks from the screener that are currently positioned on the positive side of this story.

Comfort Systems USA (FIX)

Overview: Comfort Systems USA is a Houston based contractor that designs, installs, and services heating, ventilation, air conditioning, electrical, plumbing, and fire protection systems for commercial, industrial, and institutional buildings across the United States, with a role in keeping data centers, hospitals, and other critical facilities running in extreme heat.

Operations: Comfort Systems USA generates about US$7.3b from Mechanical Services and US$2.8b from Electrical Services, with all of its roughly US$10.1b in revenue coming from customers in the United States.

Market Cap: US$68.5b

Investors watching climate resilience are focusing on Comfort Systems USA because it operates in some of the most heat sensitive environments, supplying and maintaining the cooling and electrical systems that keep AI data centers, hospitals, and other mission critical buildings operating when temperatures surge. The company’s record project backlog, returns on equity, and a rising mix of modular and recurring service work are key factors for assessing its earnings power. At the same time, investors may wish to consider its exposure to technology projects, labor market conditions, and input cost pressure. Analysts currently see the stock as close to fairly priced overall, but that headline view can gloss over important details about margins, growth quality, and how effectively Comfort Systems USA might translate today’s heat driven demand into durable long term value.

Comfort Systems USA’s record backlog and heat exposed projects could be masking a bigger shift in earnings quality, so it is worth seeing how the 3 key rewards and 1 important warning sign might reframe the whole story.

Ceres Power Holdings (LSE:CWR)

Overview: Ceres Power Holdings develops and licenses solid oxide fuel cell and electrolysis technology that can provide cleaner, efficient onsite power and green hydrogen for industries ranging from data centers and commercial buildings to heavy industry and marine applications. Its business centers on supplying core technology, stacks, modules, and intellectual property so partners can build decentralized energy systems that support decarbonization and reliability.

Operations: Ceres Power generates its revenue primarily from Asia (£28.0m), with smaller contributions from Europe (£4.6m) and North America (£0.1m).

Market Cap: £998.0m

Ceres Power Holdings operates at the intersection of extreme heat risk and the demand for more resilient power, with solid oxide systems designed for 24/7 baseload operation, fuel flexibility, and high electrical efficiency that can appeal to AI data centers and industrial users concerned about grid stress. Its licensing model and partnerships in Asia, Europe, and North America are intended to translate technology leadership into royalty income. However, the company remains loss making, trades at a high P/S multiple, and relies on higher risk funding, alongside a recent equity raise and insider selling. For investors weighing the trade off between climate resilience potential and execution risk, the full picture extends beyond headline growth forecasts.

Ceres Power’s fuel cell story sits at the crossroads of climate resilience and high risk funding, and the real tension is how that trade off could play out in the 1 key reward and 2 important warning signs (1 is major!)

Modine Manufacturing (MOD)

Overview: Modine Manufacturing designs and supplies thermal management and HVAC systems that keep data centers, EVs, industrial equipment, and commercial buildings within safe operating temperatures, helping critical infrastructure stay online during extreme heat.

Operations: Modine Manufacturing generates about US$2.1b from Climate Solutions and US$1.1b from Performance Technologies, with a small offset from corporate eliminations.

Market Cap: US$13.5b

Investors focused on climate resilience have been paying attention to Modine Manufacturing because its thermal and data center cooling products sit squarely where AI power density and rising temperatures meet, backed by long term capacity deals and a growing pipeline tied to GPU heavy sites. The company is leaning into higher growth, higher value climate and data center solutions while working to exit legacy Performance Technologies. This shift introduces execution risk, restructuring costs, and exposure if customer spending or AI buildouts slow. Recent results also show pressure on net margins and a high P/E, alongside insider selling and reliance on external borrowing. For investors weighing that trade off between heat related demand and financial risk, the full Modine story is more nuanced than the headline data center narrative suggests.

Modine’s accelerating shift toward higher value climate and data center solutions could be reshaping its earnings profile, and the real story in the 2 key rewards and 3 important warning signs might hinge on one subtle pressure point investors often overlook
