Argan is selling picks to the power boom

Q1 FY27 revenue hit a record $291 million, with gross margin of 21%.
Backlog eased to $2.8 billion from $2.9 billion as projects moved forward.
Power Industry Services made up 77.9% of Q1 FY27 revenue, so one segment drives most of the story.
AI data centers need huge amounts of steady power, which supports demand for gas and renewable projects.
The main risk is execution: a few large projects can make or break margins and timing.
Finn likes the balance sheet and recent performance, but is more careful on valuation and sentiment.

01 Running thesis

A power boom with project risk

Argan is a contractor for the power buildout. Its main job is to design, buy equipment for, build, and start up large power plants. Demand is being helped by AI data centers, which need steady electricity all day and night.

The latest quarter was strong. Argan reported record Q1 FY27 revenue of $291 million and gross margin of 21%. That supports the bull case: the company is not only winning work, it is turning that work into high-margin revenue.

The bear case is about timing and concentration. Backlog slipped to $2.8 billion from $2.9 billion, which management framed as normal project progress. Still, Argan needs new large awards to replace work that finishes. If awards pause, revenue can slow fast.

The open question is price. Finn scores Argan much better on performance and financial health than on valuation. The business is executing well, but investors may already be paying for a lot of the AI power story.

Jun 2026▲Q1 FY27 showed strong execution, with record revenue of $291 million and gross margin of 21%. The result supports the view that Argan can turn its large backlog into profitable revenue.

Jun 2026→The 10-Q updated backlog to $2.8 billion from $2.9 billion and added tariff risk on materials like steel and aluminum. The core thesis stayed positive, but cost and timing risk rose.

Mar 2026▲Backlog reached a record $2.9 billion, more than double the prior year-end level. Management tied demand to AI data centers and framed the power buildout as a major cycle through 2030.

Sep 2025▲Backlog reached about $2 billion, and management said it expected more project wins. The mix also shifted toward natural gas projects as the main growth driver.

Jun 2025▲Argan reported a record $1.9 billion backlog after a full notice to proceed on a 1.2-gigawatt gas plant in Texas. Management also said large project timelines were stretching to three to four years.

Dec 2024▲The company posted a strong Q3 FY25 and raised confidence in multiple gas-fired project starts. Management also guided gross margins around 14% to 16% or slightly higher for the next few quarters.

Sep 2024▲The initial thesis was built after Q2 FY25, when revenue grew 61% and backlog passed $1 billion. The early tension was strong demand against grid, turbine, and timing headwinds.

02 Business model

Big contracts, low asset needs

Argan is a holding company. Its subsidiaries run engineering, procurement, construction, and commissioning projects. Commissioning means testing a plant and getting it ready to operate.

The company is energy agnostic. It can build gas-fired plants, coal-fired work, solar fields, wind farms, biomass plants, and battery storage projects. Natural gas is now the main growth driver because data centers and utilities need reliable power.

This model can produce strong cash flow because Argan does not need to own power plants. It sells project skill, planning, purchasing, labor, and risk control. The tradeoff is that large projects are hard. A bad estimate, delay, or cost spike can hurt profit.

Argan also tries to keep a strong liquidity position and no debt. That matters because customers trust contractors that can handle large, multi-year jobs without balance sheet stress.

03 Product portfolio

What Argan builds

Growth engine

Gas-fired power plants

This is the core business and the main near-term growth driver. Argan builds combined-cycle and simple-cycle gas plants, which can supply steady power for utilities and data centers.

Steady

Renewable power projects

Argan builds utility-scale solar, wind, biomass, and related battery storage projects. Renewables remain part of the mix, even as management expects gas to drive growth for now.

Growth engine

Industrial construction

TRC handles industrial construction and metal fabrication, mainly in the U.S. Southeast. The segment is adding a North Carolina fabrication facility to support data center customer demand.

Option

Telecommunications infrastructure

This small segment provides wiring and construction services for utility, telecom, and federal government clients. It is not the main earnings driver today.

Cash cow

Commissioning and start-up services

Argan helps bring completed facilities online. This work is tied to its construction projects and is part of how it delivers turnkey plants.

Segment mix is from Q1 FY27 revenue. Power Industry Services was 77.9% of revenue, so results depend heavily on power project timing and execution.

05 Risk factors

What could break the thesis

Large-project execution slip

High impact · Medium odds

Argan works on large, complex, multi-year jobs. Many contracts can carry fixed-price risk, which means Argan may have to absorb some cost overruns. With backlog near $2.8 billion, a few mistakes can have a large effect.

We watchGross margin staying in the high-teens to low-20s as the $2.8 billion backlog converts to revenue.

Backlog not refilled

High impact · Medium odds

Backlog fell modestly from $2.9 billion to $2.8 billion as projects advanced. That is normal, but it raises the bar for new awards. A gap between finishing jobs and announcing new ones could pressure revenue.

We watchNew multi-hundred-million-dollar power or industrial awards over the next 10 to 18 months.

Tariffs raise project costs

Medium impact · Medium odds

Management flagged U.S. trade policy as a new risk. Tariffs on imported steel, aluminum, and other materials could raise costs or delay equipment. The key question is how much of that risk is already priced into current contracts.

We watchCompany comments on tariff pass-throughs, hedges, contract changes, or schedule delays.

Supply chain and permitting delays

Medium impact · High odds

Large gas projects now often take three to four years because of supply chain and permitting pressure. Longer timelines can push revenue further out and make planning harder. Delays can also tie up people and equipment.

We watchUpdates on turbine availability, permitting milestones, and large gas plant start dates.

Industrial ramp misses data center demand

Medium impact · Medium odds

Argan is spending $10 million to $13 million on a new North Carolina fabrication facility. The goal is to meet data center customer demand. If the ramp is late or demand softens, the Industrial segment may not backfill its backlog decline from $253 million to $225.5 million.

We watchCompletion timing for the North Carolina facility and Industrial segment backlog growth.

06 Quick answers

In one breath

Is Argan an AI stock?

Argan is not a chip or software company. It is tied to AI because data centers need large amounts of reliable electricity, and Argan builds the power plants and related infrastructure that can supply it.

Where does Argan make most of its money?

Most revenue comes from Power Industry Services. In Q1 FY27, that segment produced 77.9% of revenue, while Industrial Construction Services produced 20.0% and Telecommunications Infrastructure Services produced 2.1%.

Why does backlog matter for Argan?

Backlog is contracted work that has not yet turned into revenue. For Argan, backlog gives visibility, but it also creates execution risk because a few very large jobs can drive results.

What is the biggest concern with AGX stock?

The business is performing well, but the stock depends on continued project wins and clean execution. Finn is more positive on financial health and performance than on valuation, so price discipline matters.
