Argan's AI Power Play Is Working — But Can a $10 Billion Valuation Hold on a $2.8 Billion Backlog?

Shares of Argan Inc. surged 6.4% to $734.40 on June 17, extending a blistering 24.7% rally over five trading sessions as Wall Street continues to digest a quarter that shattered expectations. The infrastructure builder — the company that constructs the gas-fired power plants feeding America's AI data centers — is now priced as a growth stock, and the question is whether its project pipeline can justify the premium.

• A 78% Earnings Surprise Rewrote the Bull Case. Argan delivered EPS of $3.24, crushing the $1.82 forecast by 78%.

Revenue hit a record $291 million with gross margins expanding to 21% , up 50% year-over-year as recently awarded power projects ramped into active construction. That kind of beat doesn't just lift a quarter — it forces analysts to reprice every future quarter upward. Management now says annual revenue of $2 billion is achievable long-term.

• Data Centers Are Filling the Order Book, But Backlog Dipped. Argan won two major Texas contracts to build power plants totaling over 2,200 megawatts aimed at serving AI data center electricity demand.

Its industrial unit also landed a data center contract for pressure vessel fabrication, prompting construction of a new North Carolina facility. Yet backlog slipped to $2.8 billion from $2.9 billion as completed projects rolled off. CEO David Watson acknowledged "there will at times be a gap" between completions and new awards but expects "a handful of new projects over the next 10 to 18 months."

• Cash Pile and Capital Returns Signal Confidence — Insiders Signal Something Else. Argan holds $974 million in cash and investments with zero debt.

The board declared a $0.50 quarterly dividend , and expanded its buyback program to $200 million. But insiders have made 24 trades in the past six months — all sales, zero purchases.

BlackRock added nearly 944,000 shares (+80%) in Q1 2026 , suggesting big institutions are betting on the AI-power thesis even as executives take chips off the table.

• Valuation Now Demands Flawless Execution. At $734, Argan's market cap exceeds $10 billion on roughly 14 million shares. Management says only a handful of firms can build gigawatt-scale combined-cycle power plants , giving it real pricing power. But expectations are riding high, and a failure to execute flawlessly could see shares drop sharply. The stock has tripled in a year; the backlog has not.
