Aggreko, a Glasgow-based company that rents out power generators and cooling equipment, has filed paperwork with U.S. regulators for an initial public offering on the New York Stock Exchange. The move comes as data centers—the massive warehouses that power cloud computing and artificial intelligence—drive a surge in electricity demand.
In its filing with the Securities and Exchange Commission, Aggreko said it had $6 billion in secured net revenue as of July 2026. The company also reported that revenue from data center customers nearly doubled for the year ended January 3, underscoring how the AI boom is reshaping the energy landscape.
What Aggreko does
Aggreko is a temporary power specialist. It provides generators, chillers, and other equipment to utilities, miners, factories, and event organizers—anyone who needs reliable electricity or cooling on short notice. The company was taken private in 2021 by TDR Capital and I Squared Capital, two investment firms that have been preparing it for a return to public markets.
The company's financials show strong momentum. For the six months ended July 4, revenue climbed 28% to about $1.92 billion, and profit from continuing operations swung to $80 million from a $196 million loss a year earlier. The standout driver was data centers, which have become a major growth engine as tech giants and cloud providers race to build new facilities.
Why data centers matter for power
Data centers are energy-hungry. They require vast amounts of electricity to run servers and cooling systems, and they often need power quickly—before permanent grid connections are ready. That's where Aggreko comes in. The company can deploy temporary generators and cooling units to bridge the gap, a service that has become increasingly valuable as AI workloads expand.
This trend is not isolated to Aggreko. Across the market, companies are positioning to meet the power demands of AI. For example, Nano Nuclear and Tillman have signed a framework for 2 GW of AI data center power, and nVent is acquiring Maverick Power for $1.75 billion to meet similar demand. Even chipmakers are feeling the ripple effects, as Washington's focus on AI data centers has weighed on chip stocks.
What the IPO means for investors
For everyday investors, Aggreko's IPO is a chance to own a piece of the infrastructure that powers the AI boom. But it's important to understand the risks. Temporary power is a cyclical business—demand can spike during outages or construction booms, but it can also fade when permanent solutions come online.
The company's secured net revenue figure of $6 billion is a positive sign, as it suggests a strong pipeline of contracted work. However, IPOs are inherently speculative. The company will need to demonstrate that its data center growth is sustainable, not just a one-time surge.
Investors should also watch how Aggreko prices its shares and what valuation it seeks. The company's private equity owners will be looking for a profitable exit, which could mean a rich valuation. As with any IPO, it's wise to read the prospectus carefully and consider your own risk tolerance.
Broader market context
Aggreko's filing comes at a time when energy infrastructure is a hot theme. The rise of AI has created a race to secure power, and companies that provide the equipment and services to support that growth are attracting attention. Analysts have been upgrading stocks like Celestica on the back of AI data center demand, and the sector shows no signs of slowing.
For Aggreko, the challenge will be to maintain its edge in a competitive market. The company has a strong brand and a global footprint, but it faces rivals in both temporary power and permanent solutions. Its ability to lock in long-term contracts with data center operators will be key.
The bottom line
Aggreko's IPO is a sign of how deeply AI is reshaping the energy sector. For investors, it offers exposure to a company that is directly benefiting from the data center boom. But as with any investment, it's essential to do your homework and understand the risks before diving in.
The company's next steps will be to set a price range and begin the roadshow. If the IPO goes well, it could pave the way for other energy infrastructure companies to follow. For now, all eyes are on Aggreko as it prepares to make its public debut.
