STRL New Idea | March 2026

Sterling Infrastructure (STRL): $392.26, $12.0B Mkt Cap, $12.1B EV

Headquartered in The Woodlands, Texas, STRL provides E-Infrastructure, Transportation, and Building Solutions across the United States. The company has transformed from a money-losing highway contractor into a $14B data center infrastructure platform. Revenue is organized into three segments:

E-Infrastructure Solutions (69% of Q4 rev): Site development + electrical services (CEC) for data centers, semiconductor facilities, e-commerce distribution. +123% Y/y growth in Q4 (67% organic). Adj op margin: 22.2%. Serves hyperscalers including Amazon, Meta, and Google with 3-5 year project pipelines.
Transportation Solutions (20% of Q4 rev): Highway, bridges, airports, storm drainage. Rocky Mountain core. +24% Y/y growth. Adj op margin: 12.2%. Over two years of backlog. Downsizing low-bid TX heavy highway business to improve mix.
Building Solutions (11% of Q4 rev): Residential/commercial concrete, plumbing. Dallas/Houston/Phoenix. -9% Y/y decline. Adj op margin: 10.0%. Cyclically depressed; positioned for share gains on recovery.

Investment Thesis: Why STRL Works

1. Transformation Complete: From Money-Losing Highway Contractor to DC Infrastructure Platform

E-Infra growing +123% Y/y (67% organic), the biggest segment is the highest margin and fastest growing. This is the inverse of the typical E&C model.
$4.5B visibility pool (signed backlog + unsigned awards + future phase) provides 18-24 months of coverage at current run rates.
Mission-critical work is 84% of E-Infra backlog (up from 80%), driving margin durability.

2. CEC Cross-Sell Creates Integrated Moat

Site development + electrical = single-source solution for hyperscalers on mission-critical timelines. "If site dev is even a couple weeks late, the total project gets delayed months."
CEC Q4 revenue +21%. Texas market "on fire." CEC modular facility tripling to 300k sqft for prefab electrical components.
Combined offering already driving margin improvement. Cutillo: "ahead of schedule and more optimistic about putting these two together."

3. Multi-Year Secular Demand with Multiple Waves

Data centers (now): Hyperscalers talking "bigger builds, more builds" with 3-5 year pipelines. Projects evolving from data centers to data campuses.
Semiconductor (next wave, ~2027+): Micron $100B, CHIPS Act $450B+. Projects 7-10 years vs DC's 3 years. Total scope approaching $1B per project.
Geographic expansion: Texas is on fire. Meta $10B El Paso campus. Pacific Northwest entering 2027. Ohio/Indiana potential.

4. Rare Compounder Profile in E&C

5th consecutive year of 35%+ EPS growth. FY25 Adj EPS $10.88 (+53%). FY26E midpoint implies +26%.
Gross margins reached 23% and EBITDA margins exceeded 20% for first time in history.
OCF: $440M. FCF conversion to EBITDA ~80%+. Net cash balance sheet with $150M undrawn revolver.

Investment Summary: Growth Drivers, Key Risks, What to Watch

Growth Drivers

E-Infra guided +40%+ revenue growth in FY26. Legacy site dev +20%+ organic. Supported by $4.5B visibility pool.
CEC cross-sell with site development creates integrated offering. Texas market accelerating. Margin expansion path toward 25%+.
Semiconductor is the next wave: CHIPS Act, Micron, pharma. 7-10 year projects approaching $1B each.
Geographic expansion: Texas, Pacific Northwest, Northeast. Each new geography is a multi-year growth vector.
AI adoption: 15-20% incremental PM capacity from first pilots. Six AI projects now underway.

Key Risks

DC cycle duration: if 2-3 year phenomenon, multiple compresses 35-50%. Solar over-ordering parallel is the bear case.
Customer concentration is unstated. DC subset of E-Infra is the largest component but exact % not disclosed.
Hyperscaler capex slowdown would directly impact the order book. Flow-through to backlog untested.
CEC integration execution. New geographic ramps carry temporarily lower margins.
Building Solutions headwinds persist. Tough first half 2026, inventory overhang on recovery.
At ~27x FY26E P/E, premium valuation requires sustained execution.

What to Watch

DC concentration: exact % of E-Infra revenue and top customer concentration. Can't model AI capex sensitivity without this.
CEC cross-sell: named joint awards in H1 2026 in Texas. Margin accretion from combined site + electrical.
Backlog quality: cancellation provisions, contractual protections, duration. Is 1.64x book-to-burn sustainable?
Semi pipeline: which CHIPS Act projects award in 2026? Timing matters for 2027+ revenue.
Moat durability: does advantage hold when DC supply normalizes? Scale vs. temporary supply constraint.

Core takeaway: The case rests on a durable secular buildout (DC + semi + reshoring) meeting a rare scale advantage in mission-critical site infrastructure. Premium valuation requires the demand cycle to be structural, not cyclical.

Management & Capital Allocation: Operator-Led Transformation

Management

CEO Joe Cutillo (9 years): Mechanical engineer. Led the entire strategic transformation from money-losing highway contractor to $14B DC infrastructure platform. "None of us have seen this in our career."
CFO Sharon Villaverde (<1yr): From Dycom Industries (VP/CAO). Infrastructure M&A expertise. Hired alongside COO, bench deepening.
COO Dan Govin (<1yr): From Quanta Services (President, Quanta West). Electrical utility background. Directly relevant to CEC integration.
EVP Ron Ballschmiede (9yr): Former CFO of Chicago Bridge & Iron. Finance backbone through the transformation.
VP IR Noelle Dilts (2yr): Former Stifel equity research analyst covering E&C. Notable: knows exactly what buyside wants to hear.

Capital Allocation

M&A is the transformation engine: Plateau, Petillo, CEC. All at 4-6x EBITDA. Focused on geographic expansion + electrical footprint + services/skills.
Share repurchases: $74M in FY25 at avg $168.72. $26M in Q4 at avg $310.09. $374M remaining authorization.
Capex stepping up: $100-110M in FY26 (from $77M). Equipment fleet, Rocky Mountain build-out, modular facility.

Liquidity: $391M cash, $291M debt = $100M net cash. $150M undrawn revolver.
OCF: $440M in FY25. FCF conversion to EBITDA ~80%+ guided for FY26.
Pipeline: "Seeing more high-quality acquisition targets in the market today than a year ago." Owners see the opportunity ahead but can't fund the growth alone.
Focus: Geographic expansion of site dev + incremental electrical footprint + mechanical (natural progression). Fourth leg only if right strategic fit.

Why the two C-suite hires matter: CFO from Dycom and COO from Quanta, hired simultaneously, signals bench deepening for scale, not succession planning. Both bring direct E&C infrastructure expertise relevant to the next phase of growth.

Key Mix Observations

E-Infrastructure rapidly becoming ~70%+ of revenue. Biggest segment is highest-margin and fastest-growing. Operating leverage is enormous.
Transportation declining as % of total despite solid absolute growth. Downsizing low-bid TX heavy highway business improves margin mix.
Building is cyclically depressed. Positioned for share gains on recovery (Houston, Arizona). Potential tuck-in acquisitions at depressed multiples.
Organic Q4 growth was 36%. E-Infra organic growth was 67%. This is not just M&A-driven.

E-Infrastructure Solutions: The Growth Engine (69%)

Core thesis: As hyperscaler AI capex scales into the hundreds of billions, DC projects are evolving from data centers into data campuses. Sterling provides the critical site development + electrical infrastructure. "Remember when we were excited about the first 100-acre data center? We just started one in Texas, and the parking lot alone is 100 acres."

What Sterling Does

Site development (legacy): Earthwork, grading, underground utilities, retention ponds, roads, duct banks. Everything below grade and site-level to prepare a pad-ready campus.
Electrical services (CEC, acquired 2025): Exterior electrical infrastructure, duct banks, conduit, cabinets, modular/prefab electrical components. Cross-sold with site development.
End markets: Data centers (primary), semiconductor fabrication, e-commerce distribution, pharmaceutical manufacturing, advanced manufacturing.

Why Projects Keep Getting Bigger

DC projects spanning 3-5+ years with multiple phases. Future phase work released in packages. $1B+ future phase pipeline is tied to projects Sterling is actively working on today.
Next generation projects will include self-power generation on campus, creating more development scope: underground water, utilities, electrical. "The amount of stuff we will touch will continue to grow."
Semiconductor projects are 7-10 year duration (vs 3 years for DC), with total scope approaching $1B per project. "Pretty sizable for us."

TAM context: US DC construction market estimated at $48-60B in 2024/25, growing to $112-153B by 2030 (15% CAGR, Arizton/Grand View). Site development + exterior electrical (Sterling's scope) is roughly 15-20% of total DC construction cost (MEP is ~50%, building shell ~30%, site prep + civil ~20%). That implies a $10-12B addressable market today, growing to $22-30B by 2030. Sterling's $1.9B E-Infra revenue represents ~16-19% market share of the site dev + electrical TAM — dominant but not saturated. Semiconductor construction (CHIPS Act) adds another $20-30B cumulative through 2030.

Q4 2025 Performance

Metric	Q4 2025	Y/y	Context
Revenue	$521M	+123%	67% organic growth. DC was primary growth driver.
Adj Op Income	—	+91%	Strong execution on large, mission-critical projects.
Adj Op Margin	22.2%	Flat Y/y (legacy)	Legacy site dev ~25%. CEC in line with expectations.
Rocky Mtn Growth	—	+150%	Solely focused on mission-critical work.
CEC Revenue	—	+21%	Texas market "on fire." Modular facility tripling.

E-Infrastructure: Key Proof Points and Upside Levers

Already Supported

FY26 E-Infra revenue growth of +40%+ has direct management guidance. Legacy site dev +20%+ organic.
$4.5B visibility pool ($3.01B signed + $301M unsigned + $1B+ future phase) provides 18-24 months of coverage.
CEC cross-sell is "ahead of schedule." Cutillo expects "very nice awards" in Texas in H1 2026.
Rocky Mountain site dev +150% Y/y. Equipment investment will drive margins higher.
AI pilots: 15-20% incremental PM capacity. Six AI projects now underway.

What Can Add Upside Later

Semiconductor wave: CHIPS Act projects "close to shore" and expected to award in 2026. Major phase not until ~2030. 7-10 year, ~$1B projects.
Texas geographic expansion: Attacking from east (Plateau) and west (Rocky Mountain). CEC in Dallas center. "Unbelievable what is happening in Texas."
Pacific Northwest: Several projects likely released 2027. Sterling moving assets/resources in 2026.
Self-power generation on campus: Next-gen DC projects include power plants. More underground scope. Hitting ~2027-2028.
Mechanical services: Natural progression. Being evaluated alongside geographic expansion.
Vertical integration: Tuck-ins over next 12-18 months in new geographies. Equipment optimization in Rocky Mountain to match East Coast margins.

Takeaway: STRL works on the confirmed DC buildout plus CEC cross-sell. Semiconductor, geographic expansion, and modular/AI productivity are additive rather than required.

Transportation Solutions: The Cash Flow Backbone (20%)

Segment Overview

FY25 Revenue: $649M (+17% Y/y). Q4 Revenue: $153M (+24%).
Adj Op Profit Growth: +66% FY, +100%+ Q4. Strong market demand + mix towards higher margin services.
Backlog: $1.1B (+81% Y/y). Over two years of backlog. Strong bid activity continues.
Core markets: Rocky Mountain highway, bridges, airports, storm drainage.
Margin: 12.2% adj op margin in Q4. Margin expansion continuing as low-bid TX heavy highway downsized.

Funding Dynamics

Final year of current federal funding cycle (ends September 2026). Only 50-60% of total IIJA funding spent.
"The world doesn't stop" at end of cycle. Historical pattern: extension of existing bill, adjusted for inflation.
Good singles and doubles in awards. No single giant project, just steady flow.

FY26 Outlook

Revenue growth: low to mid-single digits.
Continued margin expansion as TX low-bid heavy highway winds down.
Core Rocky Mountain market continues to see good bid activity.

Why Transportation Matters

Steady cash flow generator: Provides ballast when E-Infra or Building cycles. Not the growth story, but the reliability story.
Margin improvement narrative: Downsizing low-bid work in Texas is deliberate portfolio optimization. Same playbook that worked in E-Infra transformation.
Equipment and skills transferability: Heavy equipment fleet and operators are fungible between highway and site development. Rocky Mountain resources attacking Texas from the west.
Federal funding provides multi-year visibility. Not a toggle switch.

Key point: Transportation is not the reason to buy the stock. But it provides a steady cash flow base and the equipment/skills infrastructure that supports E-Infra geographic expansion.

Key Subsidiaries

Texas Sterling (2001) — TX street & highway
Wadsworth (2009) — AZ, UT, NV, CO highway & bridge
Baniki (2011) — design-build, rail, aviation

Customers & Margin Context

State DOTs: AZ, CO, NV, UT (~50% of segment)
Alt delivery projects with high value-add
Aviation margins >50% higher than highway
Rail margins >3x highway
Low-bid heavy highway exiting TX (~$30M remaining in 2026)

Source: Stifel Research, Company Data.

Building Solutions: Optionality (11%)

Current State

FY25 Revenue: $348M (-6% Y/y). Q4: $82M (-9%).
Adj Op Margin: 10.0% in Q4. Low-double-digits guided for FY26.
Core markets: Dallas-Fort Worth, Houston, Phoenix. Residential/commercial concrete, plumbing.
Affordability challenges suppressing new home demand. "Nothing positive happening to spark or drive the residential turnaround."
FY26E: revenue decline high-single to low-double-digits. Tough first half 2026.

Recovery Potential

All three key geographies (DFW, Houston, Phoenix) expected to see population growth driving new home demand over multi-year period.
Once market turns, 3-4 months of builder inventory on ground must sell before new builds start.
Share gain opportunity: Historical precedent with Tealstone coming out of last downturn. "We think we'll pick up significant market share coming out of this, especially in Houston and Arizona."

M&A Optionality

Cutillo on Building M&A: "If the right acquisition came along in residential, multiples are down, and by the way, their earnings are down. We'd get them at a huge discount, and we'd look really smart 18 months from now."

Why It Matters

Not the reason to buy the stock. But also not a reason to avoid it.
At 10-11% of revenue and declining, Building is becoming less material to the consolidated story each quarter.
Recovery could provide incremental upside surprise. Not in any estimate.
Potential divestiture candidate to simplify the story, though management seems inclined to hold for cyclical recovery + M&A opportunity.

Financial Impact at Consolidated Level

Scenario	Building Rev	% of Total	Impact
FY26E (decline)	~$305-320M	~10%	Minimal drag on consolidated growth
Recovery (FY27+)	$370-400M	~10%	Incremental upside, share gains

Competitive Moat: Scale + Integration

Capability Stack

Scale Advantage3-4x larger than next competitor on large, complex DC projects. Can't replicate overnight.

Integrated OfferingSite prep + electrical = single-source for mission-critical timelines. Customers prefer one throat to choke.

Reliability Premium"If site dev is a couple weeks late, the total project delays months." Safety records + bonding capacity.

Hyperscaler RelationshipsAmazon, Meta, Google. Long-standing. Project pipelines extending 3-5 years. Repeat customer base.

Modular / AI EdgeCEC modular facility tripling. 15-20% PM capacity gain from AI. Widening gap vs smaller competitors.

Why Scale Matters in Mission-Critical Infrastructure

These are not commodity construction jobs. Hyperscalers need contractors who can mobilize massive equipment fleets, thousands of workers, and execute on time. Reliability is worth a premium when delay costs hundreds of millions.
Bonding capacity is a structural barrier. Smaller competitors cannot bond $500M+ projects. Sterling's balance sheet and track record provide access to project sizes others cannot touch.
Multi-phase, multi-year projects create switching costs. Once Sterling is on site for Phase 1, they have incumbent advantage for Phases 2-5+.

Competitive Landscape

Competitor	Focus	STRL Advantage
Quanta (PWR)	Electrical utility, T&D, renewable	Sterling is site dev specialist. Quanta expanding but different core competency.
MasTec (MTZ)	T&D, pipeline, clean energy	Sterling focused on mission-critical site dev. MasTec more diversified.
Comfort Systems (FIX)	Mechanical, electrical (inside building)	Sterling is exterior/site. Complementary, not directly competitive.
EMCOR (EME)	Mechanical, electrical services	Sterling is 3-4x larger on large complex site dev projects.
Regional E&C firms	Local site development	Can't bond or staff mega projects. Being acquired by Sterling (the opportunity).

Key competitive dynamic: Regional E&C owners "see this tremendous opportunity ahead of them and they're not able to capitally fund the growth." They risk being "on the outside looking in." This is why acquisition targets are improving in quality, and why Sterling's scale advantage compounds over time.

Expert call validation (AlphaSense): An Amazon Senior Construction Manager confirmed Sterling's ability to execute complex earthwork and utility packages on 60-120 acre heavy industrial sites, noting that equipment fleet ownership ensures reliability where only a few contractors can perform. A VP of Operations at a competing firm (Ames Construction) stated that by maintaining an impeccable safety record and vast equipment resources, a contractor eliminates roughly 90% of the potential competitive field. Hyperscaler customers prioritize speed of construction and protecting reputation from safety incidents over price.

Growth Levers: PM Capacity, Warehouse Recovery & Micron Opportunity

Project Manager Capacity Pipeline

Project managers are the binding labor constraint for STRL growth (not operators or equipment).
Internal program recruits and trains 5+ PMs annually starting with internships. Training program lasts 4+ years.
Adds ~$500M of annual PM capacity as program matures. PMs manage $100M+ projects after completion.
Also: Sterling Academy (Transportation), CEC University (electrical), Plateau training school (site dev).
AI tools expanding PM capacity by 15-20%. Larger projects also help: one PM on a $500M campus vs. five PMs on five $100M jobs.

E-Commerce / Warehouse Recovery

Warehouse spending moderated post-COVID but bottoming on Amazon reinvestment.
E-commerce distribution backlog +150% Y/y in Q3 2025.
Project sizes now 2.0-2.5x larger than historical. EV charging infrastructure adds scope and complexity.
HSD% of revenue mix and growing. Not in consensus estimates as a growth driver.

Micron Opportunity in New York

Micron's ~$100B semiconductor fab project in central New York. Petillo is well positioned for site development given its Northeast presence. Only the tree-clear contractor has been awarded so far. Site development award could come in H1 2026. Project spans ~7-10 year timeframe. Even if STRL doesn't win, industry capacity tightens, which indirectly benefits STRL.

Asset Repurposing Optionality

Yellow iron from Transportation can be repurposed for E-Infrastructure site dev work. Already winning DC projects in Rocky Mountain via this approach.
Traveling crews from Building Solutions commercial work can do duct bank concrete for DC projects.
Accelerates mix shift toward higher-margin E-Infra without incremental capex.

Cycle Diversification

Residential: early/mid-cycle performer
Private non-resi: mid/late-cycle performer
Public (Transportation): late-cycle / recession resilient
Diversification across all three dampens overall cyclicality, supporting a premium multiple.

US Share of Global	~22%

Sources: Fortune Business Insights, GM Insights, Research & Markets. Dec 2025 – Mar 2026.

Key point for STRL: Hyperscaler CapEx is heavily weighted toward new campus construction (site prep, infrastructure, electrical), not just server purchases. A $200B Amazon CapEx year means dozens of new campuses, each requiring Sterling's exact services.

Market Context: Stifel DC Project Tracker — Pipeline +170% Y/y, Texas +865%

Source: Stifel Research / Aterio, November 2025. "Data Center Project Tracker: Texas Seeing Notable Relative Strength."

Key Data Points

Texas	+865%	5.8x
Georgia	+232%	13.3x
Virginia	+12%	7.1x
Arizona	+238%	8.7x

Direct STRL read-through: ~45% of projects under construction are in early site development phase, which is Sterling's exact scope. Texas pipeline +865% Y/y aligns with Cutillo's forecast that TX becomes STRL's #1 market. Georgia (STRL stronghold) has 13.3x pipeline/starts ratio, the healthiest in the country.

Market Context: Time-to-Power Crisis & Construction Bottlenecks

The "Time-to-Power" Constraint

Power constraints extend DC construction timelines by 24-72 months (WRI analysis). This is the #1 bottleneck for hyperscaler expansion.
ERCOT (Texas) large-load interconnection pipeline: 200GW+ of requested load. Texas is the #1 target market.
Q4 2025: developers added only 25 GW of new capacity to pipeline (half of prior quarter), signaling grid limits.
Microsoft built 2 GW globally in 2025 alone. Plans 1.5 GW single site in Wisconsin. Acknowledged turning away customers due to power shortages.
Self-power generation on DC campuses is the emerging solution. Sterling is already preparing for this (underground infrastructure for on-site power plants).

Why This Benefits Sterling Specifically

Campuses are getting bigger: 50 acres (2018) → 1,000+ acres (2025). Bigger = more site prep scope = more Sterling revenue per project.
Complexity is increasing: Self-power, underground utilities, duct banks, conduit. More infrastructure scope per campus.
Speed premium is rising: When power delays stretch 2-5 years, the site prep contractor who can execute fast and reliably commands pricing power.
Texas expansion: Sterling is actively deploying into the #1 US DC market. Cutillo: "Texas to become our #1 market within 5 years."

Semiconductor Wave (CHIPS Act)

$52.7B in CHIPS Act subsidies + $39B manufacturing incentives driving fab construction.
7-10 year, ~$1B projects. "The early innings of semiconductor."
Sterling's site prep for fabs uses identical capabilities as DC work (fungibility moat).

Structural demand thesis: This is not a 2-3 year capex cycle. Hyperscaler CapEx commitments run through 2028-2030. Campus sizes are expanding. Power constraints are creating multi-year queues. CHIPS Act adds a parallel demand wave in semiconductor. Sterling sits at the intersection of all three trends with a capacity-constrained competitive position.

The Valuation Argument

STRL's type of work resembles civil peers (site development, earthmoving), but its FCF conversion (~70% of EBITDA) and data center exposure (>30% of revenue) align it firmly with specialty E&C peers. The market is gradually recognizing this.

Specialty peer average: 24.6x NTM EV/EBITDA
Civil peer average: 12.3x NTM EV/EBITDA
STRL current: 23.3x (1.5-turn discount to specialty avg)
Gap to best-in-class: ~7x turns (FIX at 30.3x)
Stifel: "We see a path for the multiple to converge with specialty peers over time"

Why FCF Conversion Matters

STRL expects operating income ≈ cash from operations (minimal working capital drag)
FCF conversion in mid-60% of EBITDA range, among best-in-class specialty E&C
Transportation and Building Solutions have particularly favorable working capital profiles
Building Solutions: <$1M annual capex, ~15-day cash cycles
Strong FCF supports dual capital deployment: buyback ($374M remaining) + accretive M&A

Margin Expansion: Path to 25%+

EBITDA Margin trajectory: 13.2% (FY23) ➜ 15.1% (FY24) ➜ 21.3% (FY25) ➜ 20.5-20.6% (FY26E). E-Infra adj op margin: 22.2% (Q4), ~25% (FY legacy site dev). CEC margins improving as DC mix shift accelerates.

Drivers of Margin Expansion

#	Driver	Mechanism	Status / Timeline
1	Mix Shift to E-Infra	Biggest segment is highest margin. As E-Infra grows to 70%+ of revenue, consolidated margins rise. Large, mission-critical projects carry premium margins.	In progress. E-Infra was 69% of Q4 rev vs 56% in FY24.
2	CEC Cross-Sell	Combined site + electrical eliminates subcontractor markup and improves scheduling efficiency. Small dry utility acquisition in Georgia already showing "significant margin improvements."	Ahead of schedule. Joint TX awards expected H1 2026.
3	CEC Modular Build	Tripling modular facility to 300k sqft. Pre-building components in factory reduces field electricians needed, improves productivity. "Insignificant capex, significant capacity/margin impact."	Underway. Lease signed. Impact H2 2026+.
4	Rocky Mountain Equipment	Currently using converted highway assets. Investing in purpose-built equipment suite to match East Coast operations. Same pricing, just lower cost to execute.	FY26 capex increase. $100-110M vs $77M.
5	Transportation Mix	Downsizing low-bid TX heavy highway. Focus on higher-margin Rocky Mountain core. FY25 adj op profit +66% on only +17% revenue growth.	In progress. Continued expansion in FY26.

FY26 Margin Guidance

E-Infra adj op margins: 23-24% range (FY26E). Legacy site dev ~25%. Room for CEC to improve as DC mix increases and combined projects ramp.
Transportation: Continued margin expansion as TX low-bid work runs off.
Building: Low double-digit adj op margins despite revenue decline. Cost discipline holding.
Consolidated EBITDA margin: ~20.5% guided. Slight dip from 21.3% driven by CEC acquisition mix (lower initial margins) and geographic expansion startup costs. Expected to re-accelerate.

Revenue Algorithm: From $2.5B to $4B+

The bridge does not require heroic assumptions. It needs continued DC demand, CEC cross-sell execution, and geographic expansion. Semiconductor is option value, not in the base case.

FY25A ➜ FY26E Segment Bridge

Segment	FY25A	FY26E Mid	Growth	Assumption
E-Infrastructure	$1,889M	~$2,645M	+40%	Guided +40%+. DC demand + CEC + geo expansion.
Transportation	$649M	~$670M	+3%	Low-mid single digits. Core Rocky Mtn growth.
Building	$348M	~$310M	-11%	HSD-LDD decline. Tough first half.
Total	$2,490M	~$3,125M	+25%	Guided $3,050-3,200M.

What Is In the Base Case vs. What Is Not

In the Base Case (FY26E Guidance)

Continued DC demand from existing hyperscaler relationships with 3-5 year pipelines
CEC revenue growth from TX data center market strength
Legacy E-Infra organic growth +20%+ from backlog execution
Rocky Mountain continued ramp on mission-critical work
Transportation steady in core Rocky Mountain markets
Building decline due to residential weakness

Option Value (Not in FY26E Numbers)

Semiconductor awards: "close to shore" but major phase not until ~2030
Pacific Northwest entry: assets moving in 2026, projects likely 2027
Ohio/Indiana market: potential but not on 10-yard line
Self-power generation scope on next-gen DC campuses (~2027-2028)
Building Solutions recovery and share gains
Mechanical services expansion (natural progression)
Tuck-in acquisitions at depressed multiples

Key point: The stock can work from here on confirmed growth drivers and the existing visibility pool. The option-value lanes (semi, new geographies, building recovery, mechanical) provide asymmetric upside if they hit.

Source: Bloomberg Analyst-Curated Comps, BBG Prep & Rep EW TR Index, March 30, 2026. BF = Best Forward consensus estimates.

Key takeaway: STRL trades at a +31% premium to comp group on BF EV/EBITDA (17.7x vs 13.5x mean). Premium is justified by: 67% organic E-Infra growth, 20%+ EBITDA margins, net cash balance sheet, and mission-critical moat with multi-year visibility. Within the group, only FIX (23.2x) and PWR (24.1x) trade at higher EBITDA multiples — both are best-in-class specialty E&C with similar DC exposure profiles.

Risks & Watch Items

#	Risk	Why It Matters	What to Watch
1	DC Cycle Duration	If DC buildout is a 2-3 year phenomenon rather than structural, the multiple compresses 35-50%. The solar over-ordering parallel is the bear case.	Hyperscaler capex announcements staying elevated. Backlog duration extending. Future phase pipeline growing.
2	Hyperscaler Capex Slowdown	Sterling's E-Infra demand is directly tied to hyperscaler capital deployment programs. A 20-30% capex cut would impact the order book.	Quarterly commentary on customer capital deployment plans. Book-to-burn ratios. Award activity in new geographies.
3	Customer Concentration	DC subset of E-Infra is the largest component but exact % is not disclosed. Top customer concentration is unstated.	Management commentary on customer diversification. New customer wins. Semiconductor and e-commerce contribution growing.
4	CEC Integration	Cross-sell thesis is "ahead of schedule" but joint awards are not yet announced. Integration of acquisition + geographic expansion simultaneously adds execution risk.	Named combined site + electrical wins in TX. CEC margin trajectory. Modular facility production ramp.
5	Valuation	At ~27x FY26E P/E and ~22x EV/EBITDA, the stock prices in durable growth. If growth normalizes to 15-20%, multiple compresses to 15-20x = significant downside.	NTM estimates holding. Beat-and-raise cadence. Multiple sustained on real growth, not narrative.
6	Building Solutions	Declining segment with affordability headwinds. Not the thesis, but a drag on consolidated growth and a distraction from the E-Infra story.	Revenue stabilization. Interest rate trajectory. Tuck-in M&A at depressed multiples for recovery upside.
7	New Geo Margin Dilution	New geographic expansion (Texas, Pacific NW) starts at lower margins. Equipment conversion and ramp take time.	Rocky Mountain margin improvement from equipment investment. TX margin converging to East Coast levels.
8	Labor Constraints	"If I had another 1,000 electricians in Texas, I could put them to work in 30 days or less." Tight labor limits growth rate.	Modular build adoption reducing field labor needs. AI tools expanding PM capacity. Acquisition as labor acquisition.

Price Context & Positioning — Setup Into Next Catalysts

Price History

Period	Price	Return	Context
2020 Lows	~$10-15	—	Pre-transformation. Money-losing highway contractor.
Mar 2025 (tariff lows)	$105	—	52-week low. Broader market selloff, tariff fears.

Technical Summary

52-Week Range: $104.96 – $459.72
YTD 2026: +32% (from ~$297)
1-Year Return: +247% (from ~$113)
2-Year Return: +700%+

RSI (14D): ~48 (neutral; not overbought)
Beta: ~1.35
30D Volatility: ~45%
90D Volatility: ~52%

Entry point assessment: The stock has pulled back ~15% from the $460 post-Q4 highs, creating a more attractive entry. RSI at ~48 is neutral. The 1Y move from $105 to $392 reflects a fundamentally transformed business (5th year of 35%+ EPS growth, record backlog, CEC integrated), not just multiple expansion. Current ~29x FY26E P/E is reasonable for a 25%+ EPS grower with $4.5B of visibility.

Sell-Side Consensus

7 analysts covering, all Buy-rated. Average PT (where disclosed): $489 (+25% upside). Coverage expanded from 4 to 7 in last 12 months.
William Blair (Louie DiPalma): Outperform. "Even after tenfold increase since 2020, just getting started." Projects DC revenue $977M by 2030. 18x 2027E EBITDA.
Stifel (Brian Brophy): Buy, $490 PT. Initiation Feb 2026. Positive on Texas whitespace. VP IR Noelle Dilts is former Stifel E&C analyst.
DA Davidson (Brent Thielman): Buy, $460 PT (raised from $355). CEC adds specialty electrical. Houston mgmt update positive.
Sidoti (Julio Romero): Buy, $505 PT (highest). "Execution at scale continues to resonate with larger, mission-critical projects."

STRL | High-Quality New Idea Candidate

STRL has transformed from a money-losing highway contractor into a $14B DC infrastructure platform. The combination of secular demand (data centers, semiconductor, reshoring), a rare scale advantage (3-4x larger than competitors on mega projects), and an integrated site dev + electrical offering creates a compelling compounder profile. The business just delivered its 5th consecutive year of 35%+ EPS growth with $4.5B of visibility, a net cash balance sheet, and a CEO who has been at the helm for the entire transformation.

What Makes This a Conestoga Stock

Moat: 3-4x scale on mega DC projects. Integrated site + electrical. Reliability premium on mission-critical timelines. Bonding capacity barrier.
Growth: DC secular buildout + semiconductor next wave + geographic expansion. Multiple stacked drivers, not a single-catalyst story.
Management: Cutillo (9yr) led entire transformation. Two new C-suite hires from Dycom/Quanta for next phase. VP IR is former Stifel E&C analyst.
Quality: 5th year of 35%+ EPS growth. Net cash. 83% OCF conversion. Beat-and-raise cadence. Margins at historic highs and expanding.
Durability: $4.5B visibility pool. 84% mission-critical backlog. Multi-year hyperscaler relationships with 3-5 year pipelines.
ESG: MSCI ESG Rating: A.

Negatives / Why We Could Be Wrong

DC buildout is a 2-3 year cyclical phenomenon, not structural. Multiple compresses 35-50% when orders slow.
Customer concentration is unstated. DC subset of E-Infra is likely the majority but exact % not disclosed.
At ~29x FY26E P/E and ~20x NTM EV/EBITDA, the premium multiple requires sustained execution on growth and margins.
FY27E consensus shows sharp deceleration (revenue +3.4%, EPS +6.4%). If the street is right, multiple compresses.
New geographic expansion (Texas, PNW) starts at lower margins. Integration execution carries risk.

Next Steps

Executive / Management Team — Operating Depth and Governance

Executive	Current Role	Relevant Background	Why It Matters
Joseph A. Cutillo	Chief Executive Officer (since 2017)	30 years of experience leading complex, transformational change. Previously President and CEO of Inland Pipe Rehabilitation LLC, a $200M PE-backed trenchless pipe company, from 2008 to 2015. Earlier held management roles at Ingersoll-Rand and General Electric. B.S. in Mechanical Engineering from Northeastern University.	Core operator in the case. Led the entire transformation from money-losing highway contractor to $12B DC infrastructure platform. 340,593 shares owned (~$131M). The investment thesis is built on his continued leadership.
Nicholas Grindstaff	Chief Financial Officer (since Jul 2025)	30+ years of finance and leadership experience. Previously CFO of Cinterra (utility-scale solar contractor) since late 2024. Before that, CFO of Orbital Infrastructure Group (2021–2024). Spent 20+ years at Quanta Services as VP Finance (2011–2021) and Treasurer (1999–2011). M.S. in Accounting and B.S. in Finance from University of Houston.	Deep infrastructure finance background from Quanta (20+ years). M&A, capital markets, and FP&A expertise directly relevant to Sterling's next phase of growth and acquisition strategy.
Dan Govin	Chief Operating Officer (since Aug 2024)	30 years of operations and leadership in energy infrastructure. At Quanta Services from 2007 as Regional President, President of Par Electrical Contractors, and SVP Operations. Prior roles in energy infrastructure since 1994. MBA from Crummer School at Rollins College, B.S. from University of Wisconsin Green Bay.	Operational execution for electrical services scaling and CEC integration. Quanta is the gold standard in E&C operations. His regional president experience is directly applicable to Sterling's geographic expansion strategy.
Mark D. Wolf	General Counsel, CCO & Corporate Secretary	Corporate legal and compliance leadership. Oversees governance, regulatory compliance, and M&A legal execution.	Relevant for M&A execution discipline, compliance, and governance quality as Sterling scales through acquisitions.
Noelle Dilts	VP IR & Corporate Strategy	Former Stifel equity research analyst covering the E&C sector. Joined Sterling 2023.	Notable: Knows exactly what buyside wants. Investor communication quality is above-average for SMID E&C. Coverage-quality IR presentations.

Quanta connection: Both the new CFO (Grindstaff, 20+ years at Quanta) and COO (Govin, Regional President at Quanta) come from the same tier-1 E&C platform. This is not coincidence — Quanta is the gold standard for infrastructure services scaling. Sterling is importing the operational playbook that built a $46B company. Cutillo at 9 years, 340K shares (~$131M), with no signs of departure.

Management Incentives & Governance Alignment — Proxy Read-Through

What Looks Good

60% PSUs / 40% RSUs (upgraded from 50/50 in 2024). PSU metrics: 2/3 cumulative 3-year EPS, 1/3 relative TSR vs peers (0–200% payout).
Historical payout is real: 2022 and 2023 PSU tranches both paid at 200% max on 2024 Adj EPS of $6.10 vs targets of $3.06–$3.49.
2024 STI paid 199% of target. Adj EBITDA $324.8M vs $325.1M max ceiling. Formulaic, not discretionary.
CEO special PSU: 160K shares ($27M+) with stock price milestones ($100/$120/$140). All three targets achieved.
Say-on-pay: >97%. No ISS/Glass Lewis opposition disclosed. Double-trigger CIC on 2024+ grants.
Ownership guidelines: CEO 5x salary ($5M), NEOs 3x. Cutillo exceeds at 1.4% ($131M+).

Why It Matters For The Case

Board is explicitly paying management for EPS compounding + peer-relative TSR outperformance. That matches the bull case.
Cutillo owns 436,188 shares (1.4%, ~$131M+) plus 160K special PSUs. Meaningful skin in the game at current prices.
LTI target at 350% of base salary for CEO ($3.5M target). Structure is heavily performance-levered.
83% independent board with separate Chair/CEO. 100% independent committees. All directors attended 100% of 2024 meetings.
Capital allocation discipline: M&A at 4-6x EBITDA, buybacks at avg $168.72, no value-destructive deals in 9 years.

What To Keep Balanced

Pre-2024 equity is single-trigger CIC. Only 2024+ grants have double-trigger. Legacy grants vest on CIC alone.
CIC severance for Cutillo is 3x (base + target bonus) = ~$6.5M. Executive-friendly but within market norms.
Total insider ownership only 2.7%. Most is Cutillo (1.4%) and Ballschmiede (0.8%). COO Govin has just 634 shares — too new.
Customer concentration disclosure remains a governance gap. Not disclosing DC % of E-Infra or top customer.
6-person board is lean. Added Rose and Schulz in Jul 2025 (now 8), which helps. Monitor for further additions.

Proxy takeaway: STRL is being governed and incentivized like a performance-driven compounder, not a promotional E&C story. LTI is 60% performance-based on EPS + TSR. Both recent PSU cycles paid at max (200%). CEO owns $131M+ in stock. The only meaningful governance blemishes are pre-2024 single-trigger CIC equity and the customer concentration disclosure gap.

Board & Leadership Pedigree — Infrastructure Operator DNA

Board of Directors

Board Member	Relevant Pedigree	Why It Matters
Roger A. Cregg Chairman	Independent director at Comerica, Inc. President of Avatar Properties. MBA from Kellogg (Northwestern), B.S. Accounting from Northeastern. Former executive roles in homebuilding and real estate.	Financial governance depth plus real estate/construction industry exposure. Both he and Cutillo are Northeastern alums.
William T. Bosway	CEO and Chairman of Gibraltar Industries (ROCK). Infrastructure products manufacturer.	Brings active CEO perspective from a peer-adjacent infrastructure company. Directly relevant to Sterling's industrial/infrastructure positioning.
Andrew Rose Added Jul 2025	Former President and CEO of Worthington Enterprises. Transformational operator who led Worthington through major strategic evolution.	Operational excellence and corporate transformation pedigree. Pattern-matched to Sterling's own transformation story.
David Schulz Added Jul 2025	EVP and CFO of Wesco International ($22B distribution company). Deep financial expertise at scale.	CFO of a $22B company provides board-level financial oversight as Sterling scales from $2.5B to $4B+ revenue.
Julie A. Dill	Non-Executive Director at Rayonier Advanced Materials. Prior utility and energy leadership roles.	Energy and infrastructure regulatory experience.
Dana C. O'Brien	SVP, General Counsel and Secretary at Olin Corporation.	Legal and governance expertise from a major industrial company.
Dwayne A. Wilson	Director of Ingredion, Inc. Prior senior leadership roles.	Public company board governance experience.

Takeaway: Board was refreshed in July 2025 with two additions (Rose from Worthington, Schulz from Wesco) adding operational and financial scaling expertise. Combined with the management team's deep Quanta Services DNA (CFO + COO), Sterling has assembled a leadership bench specifically calibrated for the next phase: scaling from $2.5B to $4B+, integrating acquisitions, and expanding geographically.

Transformation Architect

Joe Cutillo joined Sterling in 2017 as CEO when the company was a money-losing highway contractor trading at ~$15/share. He identified and executed the strategic pivot from commodity highway work to mission-critical E-Infrastructure, culminating in the CEC acquisition that created a $12B integrated DC infrastructure platform.

Why it matters: The entire investment case was built by one operator over 9 years. This is not a financial engineering story or a roll-up — it is a strategic transformation led by an operator who saw the DC opportunity before the market.

Bench Deepened for Next Phase

In 2025, Cutillo made two simultaneous C-suite hires: CFO Sharon Villaverde from Dycom Industries (VP/CAO) and COO Dan Govin from Quanta Services (President, Quanta West). Both are infrastructure veterans from the two most respected E&C operators.

Why it matters: This signals building the management infrastructure for scaling to $4B+ revenue, not succession planning. The hires bring M&A integration expertise (Dycom) and electrical utility operations (Quanta) — directly relevant to CEC integration and geographic expansion.

Corporate Culture: "The Sterling Way" — Employer of Choice in E&C

Safety & Operational Excellence

EMR (Experience Modification Rate): Plateau's EMR is 0.74 vs industry average of 1.00. Safety record ~10x better than broader construction industry.
"The Sterling Way" — proprietary operational and cultural framework spanning corporate strategy to daily field operations. Enforces rigorous safety, quality, and bid discipline.
Sterling Academy (Transportation), CEC University (electrical), Plateau training school (site dev) — formal training infrastructure across all three platforms.
PM training pipeline: 4+ year program recruiting and training 5+ project managers annually. Adds ~$500M of annual capacity as program matures.

Why It Matters for Investors

Safety record is a competitive moat: hyperscalers prioritize safety first, eliminating ~90% of potential competitors.
Retention and training = compounding institutional knowledge on complex mega-projects.
Employer of choice attracts labor in a tight market. "If I had another 1,000 electricians in Texas, I could put them to work in 30 days or less."

Workforce & Culture Metrics

Metric	Value
Total Employees	~5,000
Union vs Non-Union	Primarily non-union (NE exception)

4 consecutive years of beat-and-raise. Revenue guidance beaten by avg +7%. EPS guidance beaten by avg +6%. Management consistently guides conservatively and delivers upside. FY26 guide of $3.05-3.20B is ~10% above street consensus at time of guidance.

Quarterly Beat Cadence

Q4 2025: Revenue beat, EPS beat. E-Infra +67% organic.
Q3 2025: Revenue beat, EPS beat. Raised FY guidance.
Q2 2025: Revenue beat, EPS beat. Raised FY guidance.
Q1 2025: Revenue beat, EPS beat. Raised FY guidance.
Pattern: Beat every quarter, raise guidance every quarter.

M&A Strategy: Fragmented Market, Disciplined Execution, Accretive Multiples

Acquisition Criteria

Focus: Site development, specialty electrical, geographic expansion. ~95% of M&A pipeline is E-Infrastructure.
Multiples: Typical MSD-x EBITDA range. Higher for specialty (CEC at 9.6x), lower for residential (Drake at 3.8x).
Pipeline: Management evaluates >100 deals per year. Highly selective.
Integration: Decentralized model. Subsidiaries maintain brand identity (Plateau, Petillo, CEC, Wadsworth).
Balance sheet capacity: Net cash position. 2.5x leverage target provides significant firepower. $374M buyback remaining.

Potential Fourth Leg

Management has discussed adding a fourth business segment with exposure to positive infrastructure trends and/or recurring revenue.
Mechanical services (particularly piping) is a natural extension from site dev + electrical.
Self-power generation on DC campuses creates new scope opportunity.

Acquisition Track Record

Year	Target	Multiple	Strategic Rationale
2025	CEC Facilities	9.6x	Specialty electrical. DC cross-sell.
2025	Drake Concrete	3.8x	Building Solutions tuck-in.
2022	Petillo	5.0x	NE site dev. Micron exposure.
2019	Plateau Excavation	5.6x	SE site dev. Created E-Infra.
2017	Tealstone	~4x	Entered residential (DFW slabs).

Multiple arbitrage: STRL trades at low-20s NTM EV/EBITDA. Acquiring at 4-10x = highly accretive from day one. Industry remains fragmented (>10,000 competitors nationally). Regional E&C owners "see this tremendous opportunity ahead of them and they're not able to capitally fund the growth." They risk being "on the outside looking in."

Appendix: Q4 2025 Earnings Call Synthesis

Key management quotes and data points from the February 26, 2026 earnings call.

On DC Demand & Scale

"Remember when we were so excited we got the first 100-acre data center? We just started one in Texas, and the parking lot is 100 acres."
"These aren't data centers anymore, they're data campuses."
"As we look ahead to the next three to five years and work with them on their planning, we don't see anything slowing down. If anything, we continue to see it accelerating."

On Texas & Geographic Expansion

"The Texas market is on fire, to say the least. It is unbelievable what is happening in Texas."
"We're attacking that from the east, and we're attacking it from the west, and then we've got our CEC business right in the middle of Dallas."
"In the first half of this year, we're going to be able to talk about some very nice awards that take place in Texas."
"If I had another 1,000 electricians in Texas, I could put them to work in 30 days or less."

On CEC Cross-Sell & Modular

"Ahead of schedule and more optimistic about the strength of putting these two together and the responses that we're receiving from customers."
"The new facility is over 300,000 square feet. We're looking at multiple facilities throughout the U.S."
"Insignificant [capex] on what it frees up for capacity and how it positively impacts your margins."

On Semiconductor & M&A

"A semiconductor plant that are coming out will be closer to seven to 10 year projects. Instead of hundreds of millions, the total scope could approach $1 billion."
"We are seeing more high-quality acquisition targets in the market today than we did a year ago."
"A lot of these owners see this tremendous opportunity ahead of them and they're not able to capitally fund the growth."

On AI Adoption

"We picked up somewhere between 15% to 20% of incremental capacity of project managers just from our first AI project."
"We've got six AI projects underway right now."

Appendix: Geographic Expansion Map

Current & Planned Geographic Footprint

Region	Status	Key Driver	Timeline
Southeast (core)	Established	DC site development. Legacy Plateau business. Highest margins.	Ongoing. Multi-year hyperscaler programs.
Northeast (Petillo)	Established	Semiconductor (Micron $100B potential). Some DC activity emerging.	Awards expected 2026. CHIPS Act catalyst.
Rocky Mountain	Ramping	Mission-critical DC. Grew +150% Y/y. Equipment investment underway.	FY26 continued ramp. Margin improvement as equipment optimized.
Texas (CEC core)	Accelerating	DC electrical (CEC). Site dev entering from east (Plateau) and west (Rocky Mtn). Meta $10B El Paso.	Joint awards H1 2026. "On fire."
West Texas	Active	DC site development. "Actively working and winning jobs." Awards Q1 2026.	Attacking from Rocky Mountain resources.
Pacific Northwest	Entering	"Several projects likely released 2027." Moving assets/resources in 2026.	Setup 2026. Awards 2027.
Ohio / Indiana	Potential	"Fairly sizable market." Haven't figured out entry yet. "Not on the 10-yard line."	Longer-term opportunity.

Strategic Logic

Cutillo on geographic expansion: "When you see our geographic expansion taking place over the next 12 to 18 months, it's not necessarily because there's something there today. It's because we know something is coming in the future. And we're working with our customers to be prepared for that."

Geographic expansion follows customer demand signals. Hyperscalers are pulling Sterling into new geographies, not the reverse.
Each new geography starts with lower margins (equipment conversion, ramp). Margins converge to core levels over 12-18 months as purpose-built equipment deployed and processes replicated.
Tuck-in acquisitions provide instant geographic presence, local relationships, and labor force. "Pick the best ones" after establishing site dev presence.
Vertical integration (dry utilities, other services) follows initial site dev entry. Georgia dry utility acquisition already showing "significant margin improvements."

E-Infra backlog + unsigned + future phase: $3B+ aggregate. Exclusively E-Infra segment.
Transportation backlog: $1.1B (+81% Y/y). Over two years of work. Strong award activity.
Future phase is real work: Tied to existing active projects. Released in packages. "Internally for capacity planning, it's backlog for us."

Open Questions for Management Meeting

What are the backlog cancellation provisions? How firm is $3B? What happens if a customer pushes 6-12 months?
What is the backlog duration distribution? Average project timeline?
Is 1.64x book-to-burn sustainable or peak?
What triggers conversion of "future phase" to signed backlog? Timing?
How much is direct hyperscaler vs through GCs/developers?

Appendix: Sellside Research Detail — 7 Analysts, All Buy-Rated

Visual Appendix: Bloomberg RV — Premium to Comp Group

Bloomberg Relative Valuation screen. Source: Bloomberg Terminal, March 30, 2026.

What It Shows
STRL's current multiples vs. the analyst-curated comp group (FIX, EME, PWR, MTZ, IESC, DY, PRIM) with historical premium/discount analysis. BF EV/EBITDA at 17.7x represents a +31% premium to group mean of 13.5x.

Signal: The premium has expanded from near-parity to +31% as the market recognizes the business mix transformation. The premium is justified by 67% organic E-Infra growth, 20%+ EBITDA margins, and net cash. Comparable to the re-rating path of FIX (now at 23.2x) and PWR (24.1x) as they proved durability.
