Argan Inc. (NYSE: AGX) reported record fiscal year 2026 earnings on March 26, and the market barely blinked. The power plant construction company posted $944.6M in revenue, $137.8M net income — up 61% year over year — and a $2.9 billion backlog that management says will take over three years to convert to revenue. Free cash flow hit $410.8M. They have $895M in cash, zero debt.
The stock is up 194% over the past year. It’s trading at $430.25. Some analysts have a fair value north of $530. And most retail investors have never heard of it.
Here’s why Argan is the picks-and-shovels play on AI infrastructure that’s been hiding in plain sight.
What Argan Actually Does
Argan, through its subsidiary Gemma Power Systems, builds large-scale power generation facilities. That’s it. They engineer, procure, construct, commission, and sometimes maintain them. Natural gas peaker plants, combined-cycle plants, solar fields, battery storage — if someone needs a power plant, Gemma builds it.
It’s not a glamorous business. But in a world where AI data centers are consuming power at a pace that has utility executives publicly panicking, someone has to build the infrastructure. That someone is Argan.
The fiscal year ending January 2026 saw revenue of $944.6M, up 8% from $874.2M in FY2025. Net income came in at $137.8M, compared to $85.5M in the prior year. Q4 alone delivered $262.1M in revenue and $49.2M net income, with a 25% gross margin — the best quarterly gross margin the company has posted in years.
What’s driving it: AI data center developers are signing contracts at a pace that has created a multi-year backlog for anyone who can actually build reliable power generation at scale.
The Backlog Is the Story
At the end of FY2026, Argan’s total consolidated backlog stood at $2.9 billion — including $2.5 billion of new contract value added in a single year. That’s not a pipeline of possibilities. CEO David Watson called these “fully committed projects.”
The mix: 77% natural gas, 14% renewable, 9% industrial. Three gas-fired power plants totaling over 3.4 gigawatts are in the backlog, expected to convert to revenue over the next three-plus years.
That $2.9B backlog sitting on top of ~$945M annual revenue gives you roughly three years of forward visibility. Management expects natural gas to remain the dominant backlog category near-term — and given the timeline of AI data center buildouts, that makes sense. You don’t feed a hyperscale campus with solar alone.
Argan also has no debt. Their balance sheet ends the year with $895M in cash and investments and $421M in net liquidity. They raised the quarterly dividend to $0.50 per share (annualized $2.00) and have a $150M buyback authorization. The company returned $43M to shareholders in FY2026.
For a power plant constructor with a $6B market cap and nearly $900M in cash, that balance sheet is absurd.
The Bull Case: AI Is an Infrastructure Supercycle
Power demand from AI data centers isn’t theoretical anymore. Microsoft, Google, Amazon, and Meta have each announced multi-billion-dollar data center construction programs through 2028. Every one of those facilities needs a reliable, grid-connected power source. In many cases, that means a new gas-fired power plant nearby — and a construction timeline of two to four years.
Argan sits exactly at that intersection. The company’s connection to the data center buildout is indirect — they don’t build the servers, they build the power behind the servers. But the financials make the relationship clear: $2.5B in new contracts in a single year, with Watson specifically pointing to “generational increases” in demand.
KeyBanc and Citi both issued price targets above $120 earlier this year (pre-run). Analyst consensus is wider now given the stock’s move, but some analysts are modeling $531 as fair value using a 22x forward P/E on 2027 earnings estimates of $24.15 per share. At $430, that’s about 19% upside to the most commonly cited fair value.
The free cash flow story is also worth noting. AGX generated $410.8M in FCF in FY2026, a 43.5% FCF margin. That’s venture-software-company territory for a power plant builder. The reason: Gemma’s projects are structured with milestone payments that generate significant cash before costs are fully recognized.
The Bear Case: Valuation Is Stretched and Revenue Is Lumpy
This isn’t a no-brainer.
At $430.25, Argan trades at 49.8x earnings — compared to 33.7x for the US construction industry and 35.5x for direct peers. That’s a meaningful premium, and the market is essentially pricing in a sustained pipeline of high-margin data center-linked contracts.
The risk is project timing. Argan’s revenue comes from a small number of large, complex projects. When one project reaches substantial completion earlier than expected — like the Trumbull Energy Center did in Q4 — it can spike revenue. But that timing effect cuts both ways. A contract delay or budget overrun on a single project can miss a quarter badly. Revenue grew only 8% this year despite 61% earnings growth; those margins could compress if they win lower-margin projects to fill capacity.
There’s also the regulatory angle. Gas-fired power plants are increasingly facing permitting challenges in some states. Argan operates primarily in the US, with some Ireland and UK projects, and permitting timelines in some jurisdictions are getting longer. Any political shift toward restricting new gas infrastructure could lengthen project timelines.
And the stock is up 194% in a year. If Q4 had been a miss rather than a record, you’d be reading a different article. The market has priced in a lot of good news. This isn’t a value play — it’s a momentum and conviction play.

Is AGX Worth Buying at $430?
Here’s the honest answer: it depends on what you believe about the AI infrastructure buildout timeline.
If you think AI data center construction is a 5-10 year supercycle — and the backlog data, Microsoft’s $80B capex commitment for 2025, and the $2.9B in new Argan contracts in a single year all suggest it is — then a power plant builder with no debt, $895M in cash, 40%+ FCF margins, and a $2.9B backlog at 49.8x earnings is arguable.
The company is guiding conservatively. They’ve beaten estimates three of the last four quarters. Their margins are expanding because they’re winning better projects, not just more projects.
The realistic range from here: $345 if you get a contract delay and margin compression, $530+ if they execute and the backlog keeps growing. The current price reflects a lot of confidence in their execution, which has been warranted so far.
My take: Argan is one of the cleaner AI infrastructure plays available at this market cap. The complication is the valuation — you’re paying a premium for certainty, and the backlog gives you better certainty than most. If the stock pulls back 10-15% on any near-term noise, it becomes a more interesting entry.

The Verdict
Argan (AGX) just put up the best year in company history, backed by a $2.9B backlog tied directly to AI data center power demand. Zero debt. $895M cash. 61% earnings growth. The valuation is stretched at 49.8x earnings — you’re paying for a lot of good execution already. But the backlog visibility is real, the balance sheet de-risks the equity, and the 2027 estimates support a fair value north of $530.
Watch for any contract delay announcements or permitting setbacks as near-term risks. The Q1 FY2027 call (roughly May) will be the next inflection point — if backlog holds above $2.5B, the premium valuation becomes easier to defend.
