Quanta 2025-26: $44B Backlog, Data Center Becomes 10%

FY25 revenue $28.35B (+20%); Op income $1.64B (+22%); EBITDA $2.52B (+17%); NI $1.03B (+14%); EPS $6.80 (+13%). Record backlog $44B exit. 8 acquisitions in year. Data center backlog now ~10% of total. Total debt cut from $4.48B to $1.19B (-73%). FY26 mgmt guide: continued double-digit revenue + EBITDA, 20%+ adj EPS growth.

Key takeaways

• Cleanest grid + power-infrastructure cycle print in industrials. Top line +20% to $28.35B with adj EBITDA +17%. Operating income +22%. The four-year compounding (2022-25 revenue: $17.1B → $20.9B → $23.7B → $28.4B) reflects a sustained capex cycle for utilities, transmission, and now data centers.
• Backlog is the headline. Exit FY25 backlog $44B vs ~$30B exit FY24. Data center alone is ~10% of total backlog and growing fastest. Backlog now covers ~1.5× FY25 revenue — the cleanest forward visibility in industrials.
• Mega debt paydown. Total debt fell from $4.48B FY24 to $1.19B FY25 — a $3.3B reduction. Net leverage profile structurally repaired during a year of 8 acquisitions (Dynamic Systems, Tri City Group, Wilson Construction, plus 5 others). FCF $1.62B (+10%).
• FY26 setup is operating leverage at scale. Mgmt: continued double-digit revenue + net income + adj EBITDA growth, with adj EPS opportunity to grow >20%. The operating margin glide path (5.8% FY25 toward 6.5%+ FY26) compounds against larger revenue.
• Capital allocation is M&A + organic, not buyback. Dividend $-60M (token, not the thesis). Buybacks $-135M (light, not the thesis). The capital story is M&A-fueled portfolio expansion + debt paydown — Quanta is using its FCF to consolidate the fragmented utility-construction industry.

Business

Quanta Services is the largest US specialty contractor for electric power and pipeline infrastructure. Three reporting segments:

• Electric Power Infrastructure Services (~70% of revenue): The core franchise. Engineering, procurement, construction, and maintenance for electric utility transmission + distribution; substations; renewable generation; and increasingly data center power infrastructure. Customer base: investor-owned utilities (Duke, Southern, Dominion, AEP, etc.), municipals, cooperatives, and increasingly hyperscalers buying turnkey power for data center campuses.
• Renewable Energy Infrastructure Solutions (~17% of revenue): Solar, wind, and battery storage EPC. The Blattner Energy acquisition (2021) anchors this segment. Long-cycle utility-scale renewable build-outs.
• Underground Utility & Infrastructure Solutions (~13% of revenue): Pipeline + facility services for natural gas distribution, transmission, and water. Steady, less-AI-narrative, but high recurring component.

Strategic position: Quanta sits at the intersection of three structural demand cycles all running simultaneously: (1) grid reliability + resilience — utilities are catching up on aging T&D infrastructure after a decade of underinvestment; (2) generation transition — renewable build-out + nuclear refurb + gas peaker additions; (3) data center capex — hyperscalers building dedicated power infrastructure at scale (the fastest-growing piece of backlog at ~10% and rising).

The competitive moat: scale (largest specialty workforce in the category at ~58K employees), geographic footprint (operating across all states), and the ability to mobilize crews to anywhere a customer needs them. Smaller competitors don't have the scale to take on multi-billion-dollar utility programs.

M&A cadence is structural. FY25 closed 8 deals — Dynamic Systems (industrial process), Tri City Group (Mountain West utility), Wilson Construction (Pacific NW heavy civil), plus five smaller bolt-ons. The pattern: acquire regional contractors with utility relationships, integrate them into the Quanta national platform, and cross-sell capabilities.

FY25 financial performance

Three things to flag:

• Operating margin expanded slightly despite heavy M&A integration — discipline on the project-level margin while absorbing 8 deals.
• The debt paydown ($4.48B → $1.19B) is funded by FCF + asset monetization; the magnitude is unusual and signals balance sheet strategy shift toward optionality.
• Backlog 1.5× of revenue is the highest in Quanta's history. The 10% data center share is the freshest narrative; the bulk remains utility T&D.

Q4 alone: Revenue $7.8B with adj EBITDA $845M (margin ~10.8%) — the high-water benchmark for this kind of business.

Capital allocation

• Capex: $-609M FY25 (2.1% of revenue). Capital-light service business — the heavy assets are crews + equipment, not real estate.
• Dividends: $-60M FY25 (token). Quanta does not run a dividend-yield strategy.
• Buybacks: $-135M FY25 — modest, opportunistic.
• M&A: $4-5B+ deployed cumulatively over recent years. FY25 alone added 8 companies. Quanta is the consolidator of the utility-construction category.
• Debt paydown: $-3.3B in FY25, the structural balance sheet repair year.

FY26 outlook (per Q4 2025 call, 2026-02-19)

The $44B starting backlog provides ~1.5× FY26 revenue coverage at the start of the year — this is the kind of visibility that makes Quanta's guide unusually credible. The +20% adj EPS opportunity reflects: (a) revenue growth above 10%, (b) operating margin further expanding ~50bp on mix toward higher-margin work, (c) modest share count benefit, (d) lower interest expense on the now-paydown debt stack.

Key risks

• Project execution + skilled labor: Quanta's biggest execution risk is project-level cost overrun. Skilled electrician shortage in some regions could compress margin if labor costs run hotter than priced.
• Interest rates / utility capex cycle: If utility capex retrenches (regulatory delays, spending caps, IRA program changes), the segment that's 70% of revenue compresses.
• Data center concentration risk: The fastest-growing slice carries customer concentration — if hyperscaler capex pulls back, this lever weakens.
• M&A integration: 8 deals in FY25 is a lot. Integration costs / margin dilution from acquired contractors is the standing risk.
• Renewables policy: IRA Section 45/48 rate stability and interconnection queue dynamics matter for the 17% renewables segment.
• Weather: Storm restoration is a meaningful service line. Mild seasons compress this revenue stream.

Bottom line

Quanta FY25 is the textbook quality industrial year: +20% revenue, +13% EPS, +47% backlog growth to $44B, $3.3B debt paydown, 8 acquisitions integrated, and the data center narrative just becoming the fastest-growing slice. FY26 setup is unusually clean — backlog provides 1.5× revenue visibility, mgmt guides continued double-digit + 20% EPS upside, balance sheet now flexible. The structural risk is utility capex cycle and skilled labor cost; both are discount-window concerns rather than active threats. This is the kind of name that earns its premium multiple while the multi-cycle tailwinds compound.
