Allegiance (TMC) Q4 2025: Backlog Surges 49%, Extending Data Center Visibility to 2029

2026-03-27 | By EarningsIQ Research

Allegiance capped 2025 with a surge in backlog and organic growth, fueled by data center demand and expanded fabrication capabilities. The Bowers acquisition and a robust union labor pipeline position the company for multi-year delivery visibility, while margin expansion and disciplined capital allocation underpin a raised 2026 outlook. With data center and diversified end-market exposure, Allegiance is building durable competitive advantages as project scale and planning horizons lengthen.

Summary

• Backlog Expansion: Multi-year data center awards and a 49% backlog jump provide long-term revenue visibility.
• Fabrication and Labor Scale-Up: Capacity and skilled workforce additions support accelerating project execution.
• 2026 Guidance Raised: Upwardly revised revenue and EBITDA targets reflect confidence in sustained demand and integration progress.

Performance Analysis

Allegiance delivered record quarterly revenue and adjusted EBITDA, with the majority of growth organic and broad-based across segments. The installation and maintenance (I&M) segment, which now accounts for over three-quarters of revenue, posted a 44% YoY increase, led by demand from data center and technology clients. Fabrication-only work, primarily direct liquid-to-chip cooling systems, grew as a share of I&M, supporting margin gains. Engineering and consulting revenues grew at a slower 10% pace, with strength in program management and project services offsetting flat engineering and design activity.

Adjusted gross margin rose to 21.2%, up nearly a full point YoY, driven by project execution and a favorable mix of higher-margin fabrication work, even as engineering and consulting margins declined slightly due to service line mix. SG&A efficiency improved, with adjusted SG&A as a percent of revenue down versus last year despite public company costs. Net leverage declined to 2.0x pre-acquisition, and liquidity improved, reflecting strong operating cash flows and disciplined working capital management.

• Backlog Momentum: Consolidated backlog and awards reached $3.7 billion, up 49% YoY and 20% sequentially, with organic growth in both segments.
• Book-to-Bill Strength: The quarterly book-to-bill ratio hit 1.9x, signaling outsized demand relative to current revenue levels.
• Fabrication Mix Shift: Fabrication-only revenue grew from mid-single digits to mid-teens percent of I&M, supporting margin expansion and strategic flexibility.

Backlog duration is lengthening, with project deliveries extending into 2029 and more than half of current backlog expected to convert in 2026. This multi-year visibility is rare in engineered services and positions Allegiance to capitalize on secular data center and infrastructure trends.

Executive Commentary

Strategic Positioning

1. Data Center Demand as a Multi-Year Engine

Allegiance is capitalizing on the secular boom in data center construction, with fabrication and installation work for hyperscale and technology clients driving both backlog and revenue growth. The company is now engaged in delivery planning with clients as far out as 2029, a testament to its entrenched relationships and execution track record. This visibility is underpinned by blue-chip client commitments and a growing share of fabrication-only projects, which offer higher margins and geographic flexibility.

2. Labor Force and Capacity as Competitive Moats

The ability to scale a unionized craft labor force—now at 6,600 skilled workers—has enabled Allegiance to win and execute large-scale projects even in tight labor markets. The addition of 1,700 craftspeople via Bowers and ongoing organic hiring reinforce the company’s reputation as a preferred employer and partner. This labor depth, coupled with fabrication capacity expansion to nearly 1.3 million square feet, creates operational leverage and supports future growth.

3. Balanced Portfolio and End-Market Diversification

While data center activity garners attention, Allegiance maintains a diversified customer base across life sciences, healthcare, education, and state and local government. Management highlighted steady growth in these segments, with education and life sciences benefiting from energy efficiency investments and onshoring trends. This balance reduces cyclicality and supports a more stable revenue base over time.

4. M&A Integration and Cross-Selling Synergies

The Bowers acquisition extends Allegiance’s mechanical contracting reach into the critical Northern Virginia/DC data center corridor, expands fabrication capacity by 50%, and unlocks cross-selling with existing engineering and electrical services. The recent Metrix tuck-in adds engineering depth in the Pacific Northwest, targeting the education market with strong margins and cultural fit. Early integration progress and regulatory approvals ahead of schedule signal operational discipline and future synergy realization.

5. Financial Discipline and Capital Allocation

Leverage reduction, liquidity improvement, and focused growth capex reflect Allegiance’s disciplined approach to capital allocation. Nearly two-thirds of 2026 capital spending is earmarked for growth, primarily fabrication capacity, while working capital management and public company readiness have not diluted margin progress. The company’s use of IPO proceeds to pay down debt and the upsize of its revolver provide flexibility for further strategic initiatives.

Key Considerations

Allegiance’s Q4 performance and 2026 outlook highlight a business scaling into secular growth markets while maintaining operational discipline. Investors should weigh the following:

• Backlog Duration and Quality: Multi-year data center commitments extend revenue visibility, but also raise execution and planning complexity as project scale increases.
• Fabrication Margin Tailwind: The shift toward fabrication-only work supports gross margin expansion, but future mix will depend on competitive dynamics and Bowers integration.
• Labor and Capacity as Differentiators: Rapid workforce growth and fabrication expansion provide a supply-side moat, yet require continued investment to sustain quality and efficiency.
• End-Market Diversification: Resilience in life sciences, healthcare, and education offsets data center cyclicality and supports a balanced growth profile.
• M&A Integration Risk: Successful Bowers and Metrix integration is critical for realizing cross-selling and scale benefits, especially as the company moves into new regions and service lines.

Risks

Execution risk rises as Allegiance manages a larger, more complex backlog and integrates major acquisitions. Supply chain disruptions, while currently minimal, could re-emerge as project scale and geographic reach expand. Margin sustainability depends on mix, competitive pricing, and successful integration of new capacity and labor. Regulatory changes or delays in end-market funding, particularly in education and public sectors, could impact growth trajectories.

Forward Outlook

For Q1 2026, Allegiance guided to:

• Revenue of $925 million to $950 million
• Adjusted EBITDA of $90 million to $100 million

For full-year 2026, management raised guidance:

• Revenue of $3.7 billion to $3.9 billion
• Adjusted EBITDA of $400 million to $430 million

Management cited strong backlog conversion, robust demand across core and acquired businesses, and expanding fabrication capacity as drivers of the upward revision. Interest expense is expected in the high $50 million range for the year, with capex focused on growth projects.

• Backlog burn expected to be just over half in 2026, with remainder extending into 2027 and beyond
• Seasonality peaks in Q2 and Q3, particularly within education project management

Takeaways

Allegiance’s Q4 results confirm its emergence as a scale player in data center and infrastructure services, with backlog, labor, and fabrication capacity as core advantages.

• Secular Demand Capture: Multi-year data center and diversified end-market growth underpin visibility, while fabrication mix and labor scale support margin progress.
• Integration and Execution Watch: Bowers and Metrix integration is key for realizing cross-selling and operational leverage, with early progress noted but ongoing complexity ahead.
• Future Focus: Investors should monitor backlog duration, project mix, and labor dynamics as Allegiance navigates larger, longer-term project cycles and potential shifts in customer demand or funding.
