Argan's Power Margin Hits 23.6%: Is the Earnings Upside Sustainable?

Argan, Inc.’s AGX Power segment delivered a standout performance in the first quarter of fiscal 2027, with gross margin expanding to 23.6% from 20.6% a year ago. The improvement came alongside a sharp increase in activity, as Power revenues rose to $226.7 million from $160.4 million in the year-ago quarter. Gross profit from the segment consequently increased to $53.6 million from $33 million.

Argan’s margin expansion was driven squarely by strength in the Power segment, where a more favorable project and contract mix combined with disciplined execution to lift profitability. The early substantial completion of the final Midwest Solar and Battery Project and the completion of the Trumbull Energy Center provided additional upside, helping push consolidated gross margin to 21% from 19% a year earlier. The improvement underscores how effective project execution is translating into stronger company-wide earnings power.

The sustainability case is strengthened by the scale of Argan’s existing Power workload. The segment ended the quarter with approximately $2.5 billion of backlog, while consolidated backlog stood at $2.8 billion. Argan’s Power portfolio includes four U.S. gas-fired plants totaling more than 4.1 gigawatts. Several major projects are moving into more active construction phases. These include the 1.2-GW Sandow Lakes Power Station, a 1.4-GW Texas combined-cycle facility, an 860-MW Texas thermal project and a roughly 700-MW combined-cycle plant. Management said construction activity is ramping across several of these projects.

Still, sustaining a 23.6% Power margin may be challenging. Management noted that several major projects remain in their early stages and carry execution risks. It also indicated that consolidated blended margins have generally ranged from the high teens to the low 20s. Thus, while the latest margin level may fluctuate, Argan’s strong execution, expanding Power activity and multiyear backlog suggest that earnings could remain robust.

How Argan Stacks Up Against Quanta and EMCOR in Power Infrastructure

As Argan pursues larger power-generation projects, it competes in an infrastructure market that also includes significantly larger contractors such as Quanta Services, Inc. PWR and EMCOR Group, Inc. EME. Unlike these more diversified peers, Argan remains heavily concentrated on power-generation EPC work, with its Power segment accounting for 78% of first-quarter fiscal 2027 revenues and about $2.5 billion of backlog. 

Quanta is benefiting from broad demand across utility, generation and technology infrastructure. In the second quarter of 2026, revenues reached $9.6 billion, while backlog climbed to a record $53 billion. Management said larger utility-generation and technology load-center programs are still in the early stages and should build over the coming years. Quanta is also expanding its generation capabilities, although it remains selective about contractual risk on combined-cycle projects.

EMCOR is seeing similarly strong demand from mission-critical construction. Second-quarter 2026 revenues increased 19.8% to $5.15 billion, while remaining performance obligations surged 44% year over year to a record $17.14 billion. Data centers remain a major growth driver, with Electrical Construction revenues rising 24% and Mechanical Construction revenues climbing 31%. Management also noted that AI data center projects are becoming larger and more complex, with projects increasingly reaching 100-200 MW or developing into multi-building campuses.

For Argan, the competitive backdrop reinforces the value of execution. While Quanta and EMCOR bring greater scale and diversification, Argan’s focused expertise in complex gas-fired EPC projects and its 23.6% Power gross margin highlight its ability to generate attractive profitability from a more concentrated project base.
