Shares surged 6.2% to $439.08 after Argan, the power-plant builder, posted a second quarter that wasn't just good — it blew past every estimate on every metric. The question now: with a price-to-earnings ratio already stretching above 36x, how much more growth is the market willing to pay for upfront?

Revenue Crushed Forecasts by Nearly 28%

Analysts expected Argan to post earnings of $2.64 per share and revenue of roughly $300.5 million. Instead, the company delivered $384.0 million in revenue — a 61.5% year-over-year leap — and diluted EPS of $3.76, beating the Street by more than a dollar. Adjusted EBITDA hit $70.0 million, up from $36.2 million in the year-ago period. This isn't a marginal beat; it signals the company is converting its massive backlog into real cash faster than anyone modeled.

The Power Segment Is the Whole Story

Power-industry construction — building natural-gas plants and renewable facilities — generated $301 million, or roughly 78% of total revenue, growing 53% year over year. Argan has secured several major gas-fired power plant projects in Texas and other regions, capitalizing on rising electricity demand fueled by AI data centers, EV adoption, and manufacturing reshoring.

During fiscal 2026, the company added $2.5 billion in new contract value, pushing its project backlog from $1.4 billion to $2.9 billion, with the Power segment alone at $2.7 billion. However, total project backlog has declined from those earlier levels , suggesting Argan is burning through work faster than it's replenishing — a metric to watch closely.

A Fortress Balance Sheet Gives It Room to Bid Big

Argan held $1.03 billion in cash and investments and carries no debt. That gives it substantial flexibility to support large-scale construction opportunities. The company also continues returning cash through a $0.50-per-share quarterly dividend. But Argan still offers no formal financial guidance, leaving investors to guess at how its backlog will translate into future quarters.

The Valuation Question Looms Large

AGX is up 97.1% year-to-date, trading at roughly 36.3x earnings — rich for a construction company. The stock has now beaten Wall Street estimates for multiple consecutive quarters by wide margins. If power-infrastructure demand holds, Argan's backlog justifies the premium. If project timings slip or new awards slow, that lofty valuation has little margin for error.
