Argan (AGX): The AI Power EPC Titan, Zero Debt + $2.9B Backlog

Argan, Inc. (NYSE: AGX), headquartered in Arlington, Virginia, is a holding company whose core business is engineering, procurement, and construction (EPC). Through its subsidiaries — primarily Gemma Power Systems — it delivers full turnkey EPC services for natural gas, biofuel, and renewable power plants to utilities in the US, UK, and Ireland. The company's fiscal year ends January 31 each year, so "FY2026" refers to the fiscal year from February 2025 through January 2026.

AGX's business model looks plain at first glance: take on power-plant construction contracts, deliver on completion, and collect the engineering fee. But look closer and you'll find an extremely scarce, high-barrier franchise business — the number of contractors in the US with full EPC capability for large combined-cycle gas plants can be counted on one hand, and the thresholds for qualification certification, engineer credentials, bonding capacity, and project execution track record make it nearly impossible for a new entrant to reach standard in a short time.

More importantly, AGX's trajectory lines up precisely with a historic power-demand boom: AI data centers, reshoring manufacturing, and EV-charging infrastructure are together driving the largest expansion of the US power grid in decades, and combined-cycle gas plants are the most important source of baseload power in that expansion. Argan's CEO David Watson calls this "the early stage of power construction" — and with a $2.9 billion backlog and a steady stream of new inquiries, that assessment is hard to argue with.

Core Business: Power Industry Services

The power-plant EPC service Argan delivers through Gemma Power Systems is a "turnkey" engineering service: from feasibility studies, engineering design, and equipment procurement, to on-site construction and system commissioning, all the way to handing over a complete power plant to the owner — Gemma manages the entire process. This model lets clients (utilities, independent power producers) focus solely on operating the plant, without having to manage complex engineering coordination themselves.

For full-year FY2026, Power Industry Services accounted for the vast majority of AGX's total revenue — Q4 Power revenue of $204M made up 77.9% of the quarter's total revenue of $262M. The remainder came from two secondary segments: Industrial Services ($53M) and Telecom Data Infrastructure ($5M).

Why Is Power-Plant EPC a Franchise Business?

Building a large combined-cycle gas plant (700 MW to 1,400 MW scale) involves engineering design, equipment procurement (primarily large gas turbines from GE or Siemens), on-site construction coordination, electrical-system integration, and commissioning — typically taking 3 to 4 years, with contract values routinely in the $500 million to $2 billion-plus range. Contracts of this scale demand qualifications including:

(1) a track record of successfully delivering multiple large power plants (a trust moat with owners); (2) substantial bonding capacity — AGX's $895 million in cash gives it far more bonding headroom than smaller competitors; (3) the ability to manage complex equipment procurement and subcontractors; (4) a scarce talent pool of engineers and project managers. Together these requirements form a substantial barrier to entry, giving Argan's Gemma Power Systems a scarce position as one of the few contractors capable of taking on GW-scale projects in the large US natural-gas EPC market.

FY2026 Overview of Projects Under Construction and In Hand

Explosive Growth in Backlog

Backlog exploded from $1.4 billion at the end of FY2025 to $2.9 billion at the end of FY2026 (+107%), adding $2.5 billion in new contract value in a single year. Against FY2026 annualized revenue of roughly $945 million, a $2.9 billion backlog represents roughly 3x annualized revenue visibility — an extremely high margin of safety for the engineering-services industry, meaning most of FY2027 and FY2028 revenue is already locked in.

Full-Year FY2026 Results (through January 31, 2026)

Q4 FY2026 Quarterly Highlights (through 2026/01/31)

Q4 FY2026 EPS of $3.47 beat the $2.13 estimate by a full 62.9%, the largest single-quarter beat of any of the twelve names in this series. This wasn't a one-off accounting adjustment — it reflects genuinely stronger earning power as gross margin jumped from 20.5% to 25.0%, the combined effect of an improved project mix (a higher share of high-margin projects) and better execution efficiency, which turned relatively steady quarterly revenue into markedly higher profit.

Cash Fortress: AGX's Most Distinctive Competitive Edge

$895 million in cash and investments, $421 million in net liquidity, and zero debt — for Argan, with a market cap of only about $6.3 billion, this balance sheet means cash equals over 14% of market cap. More importantly, that cash generates a meaningful investment return every year (management calls it a "meaningful investment yield"), contributing directly to pretax profit — an earnings source that's easy for the market to underrate in a high-interest-rate environment.

The ample cash reserve also supports AGX's two-pronged shareholder-return strategy: (1) in April 2026, the company announced raising its quarterly dividend to $0.50/share (annualized $2.00), while keeping flexibility for special dividends; (2) its share-buyback program was expanded from $150 million to $200 million, with the expiration extended to January 31, 2030 — signaling management's long-term confidence in the stock.

Understanding AGX's market opportunity requires first understanding the structural imbalance in US power supply and demand. According to multiple independent studies, US power demand is expected to see its first large-scale growth in decades over the next ten years, driven by AI data centers (annual demand growth of 15–20%), reshoring manufacturing (large-scale manufacturing facility investment driven by the CHIPS Act and IRA), and EV adoption (charging demand).

Against this backdrop, the supply side of the power-plant EPC market AGX operates in is extremely scarce. As management describes it, "since we announced our new projects, inquiry volume has continued to far exceed our capacity to take on new work." This "demand far exceeding supply" dynamic lets AGX be selective and price the most attractive projects higher — directly explaining why FY2026 gross margin improved substantially from 16% to 20.5% (and even hit 25% in Q4).

"The rapid growth of AI and data centers, the electrification of everything, the need to replace aging power plants, and years of underinvestment in power infrastructure — these drivers together create a growth runway that we believe has considerable duration. Importantly, the buildout of power infrastructure today is still in its early stages, and the combined-cycle projects we take on typically run three to four years." — David Watson, President & CEO, Argan Inc., FY2026 Q4 earnings call, 2026/03/26

  $2.9B backlog covers 3 years of revenue visibility
  As of January 31, 2026, AGX's backlog stood at $2.9 billion — against FY2026 annualized revenue of $945 million, that's roughly 3x annualized revenue visibility. That means most of FY2027 revenue (estimated at over $1 billion) is already supported by the existing backlog, giving very high earnings certainty. Construction revenue from the Lordstown 950 MW plant (completion FY2027 Q1) and several Texas projects (completion 2028) will be steadily recognized throughout FY2027.

  Gross margin expansion continues: heading from 20.5% toward 25%+
  FY2026 Q4 gross margin already reached 25.0%, well above the full-year average of 20.5%, showing pricing terms on newly signed contracts keep improving. As AI power demand stays strong and EPC supply remains scarce, management's pricing power in new contract negotiations is expected to keep strengthening, with FY2027 overall gross margin likely to hold or exceed the Q4 FY2026 high.
• 3
  S&P index inclusion: structurally more institutional buying
  In March 2026, Argan was announced for inclusion in an S&P index (expected to be a constituent of the S&P MidCap 400 or S&P 500 index family); after the earnings release, the stock spiked intraday by 38% to an all-time high of $579. Passive inflows and increased institutional allocation from S&P index inclusion are structural catalysts for stock liquidity and valuation.

  New project pipeline stays abundant, with new FY2027 contracts in sight
  On the Q4 FY2026 earnings call, management explicitly stated that new project inquiry volume "far exceeds our capacity to take on new work," and the company is evaluating bidding opportunities on more large power-plant projects. Extrapolating from the $2.5 billion in new contracts added in FY2026, FY2027 could see a similarly sized increment of new contracts, further boosting the backlog.
• 5
  Investment income on cash becomes an extra earnings source
  The $895 million in cash and investments generates meaningful investment income each year in the current high-rate environment, which management calls a "meaningful investment yield." If the Fed holds rates at a relatively elevated level, this income stream keeps contributing directly to pretax profit — an implicit earnings source that's almost entirely overlooked by market analysis.
• 6
  Concentrated exposure advantage in the Texas ERCOT market
  Texas is one of the states with the densest AI data-center and reshoring-manufacturing investment in the country, and the ERCOT grid also has the most pronounced power shortfall. AGX's multiple power-plant projects in Texas (860 MW, 1,200 MW, 1,400 MW) let it directly benefit from this geographically concentrated demand boom, which overlaps heavily with the AI infrastructure buildout cycle.

AGX's valuation puzzle: its EPS growth rate (FY2026 +58%, expected to remain high in FY2027) makes the traditional P/E look elevated, but the "true enterprise valuation" net of cash (EV/EBITDA) shows a FY2027 multiple below 25x — given the business's high certainty ($2.9B backlog), that valuation is actually quite reasonable. The stock briefly touched a post-earnings high of $579 before consolidating back to around $430, suggesting the market is now digesting the volatility.

• ✓
  Price above the 150MA and 200MA: $430 is well above both moving averages; the post-earnings surge has reestablished the technical advantage.
• ✓
  150MA above the 200MA: Moving averages are fully in a bullish stack, confirming the long-term uptrend.
• ✓
  200MA trending up: Climbing steadily since the start-of-year low, direction confirmed upward.
• ✓
  50MA above the 150MA and 200MA: The moving averages realigned after earnings, and the bullish structure is restored.
• ✓
  Up more than 30% from the 52-week low: Up over 170% from the 52-week low (around $150–160).
• ⚠
  Within 25% of the 52-week high: $430 vs. the $579 high — roughly 25% below the high, near the edge, needs to be watched for a consolidation pattern.
• ✓
  RS outperforming the broad market: Sharply leading the S&P 500 since the FY2026 earnings release, estimated RS of 95+.
• ✓
  Sustained institutional accumulation: S&P index inclusion is bringing passive inflows and increased institutional allocation.

Argan Inc. is the simplest, most straightforward story in this twelve-name research series, with the cleanest financials and the highest growth visibility. There's no complex business model to untangle, no tech-stock valuation fog to see through — just: the largest power-construction cycle in US history + the scarcest EPC contractor + a zero-debt cash fortress + a $2.9 billion backlog.

CEO David Watson's statement that "power construction is still in its early stages" is strongly backed by the $2.9 billion backlog. Against the resonance of AI data centers, reshoring manufacturing, and grid modernization, AGX's project pipeline visibility is expected to stay elevated through FY2027 and FY2028, and every new GW-scale project signed further extends this growth runway.

For options traders, AGX is a high-potential but also high-volatility name (the 38% single-day post-earnings spike alone tells you that). We'd suggest waiting for volatility to compress after earnings, and once a low-volatility VCP consolidation pattern forms technically, building a position no larger than 5% RU with a Bull Put Spread, with the support strike set below the $380–$400 consolidation zone.
