With robust bidding activity and strategic pivot toward higher-margin verticals such as electrical and data centers, Shimmick is positioned for accelerated growth and profitability through 2026 and beyond.
Summary
- Backlog Quality Inflection: Non-core projects now under 5% of backlog, supporting margin consistency.
- Margin Expansion Momentum: Core project gross margins rose sharply as disciplined bidding and execution took hold.

Business Overview
Shimmick is a U.S.-based infrastructure construction and engineering firm specializing in water, power, transportation, and coastal resilience projects. The company generates revenue through large-scale public and private contracts, with major segments including core infrastructure (water, wastewater, flood protection), specialty electrical construction (Axia Electric, focused on power and data centers), and legacy non-core projects. Its business model is anchored in self-performed work and project selectivity, targeting technically complex, high-value projects across the U.S.
Performance Analysis
Shimmick’s Q1 2026 results underscore a structural shift in business mix and execution discipline. While consolidated revenue declined year-over-year as legacy non-core projects wound down, core project gross margin surged to 11%, nearly doubling from the prior year, and overall gross margin improved to 12% from 4%. The wind-down of non-core work—now less than 5% of backlog—removed a persistent drag on profitability, with management emphasizing that future quarters will benefit from a more favorable revenue mix.
Backlog growth was the standout metric, with total backlog reaching $944 million, the highest in over two years, and new awards booked in Q1 totaling $289 million. The resulting book-to-burn ratio of 2.6 signals strong demand and revenue visibility, especially as new projects in water, flood protection, and data centers ramp through the year. General and administrative expenses remained flat, reflecting ongoing overhead control as the business scales. Management reaffirmed full-year guidance for double-digit revenue growth and a step-change in adjusted EBITDA, citing robust project pipeline and higher-margin work entering execution.
- Backlog Expansion Outpaces Burn: New awards and disciplined bidding drove record book-to-burn and backlog levels.
- Margin Profile Improves as Mix Shifts: Exit from loss-heavy legacy work boosts core gross margins and sets up future profitability.
- Cash Flow Outlook Brightens: Legacy project completion and upfront cash from new awards expected to strengthen liquidity through 2026.
Shimmick’s financial trajectory now reflects a business less encumbered by legacy risk, with margin and cash flow leverage set to accelerate as new project awards convert to revenue.
Executive Commentary
"We are continuing to make progress on our strategy, which centers around growing our pipeline by bidding and winning work aligned with our expertise, winding down non-core projects, and executing at a high level to deliver consistent margins."
Yarel, Chief Executive Officer
"The $5 million increase in gross margin was driven by $3 million from new projects and $2 million from existing projects. This means we will continue to see favorable mix impact on total gross margin moving forward on a year over year basis."
Todd Yoder, Chief Financial Officer
Strategic Positioning
1. Core Backlog Dominance
Shimmick’s backlog is now overwhelmingly composed of core, higher-margin infrastructure projects, with non-core work reduced to under 5%. This strategic shift enables more predictable execution and financial results, with management emphasizing selectivity in project bidding and a focus on technical complexity where the company’s self-perform model confers competitive advantage.
2. Margin-Driven Bidding Discipline
Project selectivity is translating directly into margin expansion, as the company leverages its strong backlog position to pursue contracts with higher bid margins, particularly in the 10–20% range. The exit from loss-heavy legacy projects removes a structural drag, allowing Shimmick to target and win work that aligns with its operational strengths and risk appetite.
3. Electrical and Data Center Growth Pillars
The Axia Electric segment, specialty electrical construction focused on power and data centers, is emerging as a key pillar for medium-term growth. Management highlighted increasing bid activity and customer engagement in data center markets, particularly in Texas and Reno, positioning Shimmick to capture share in this high-demand vertical as projects move from bid to execution.
4. Operational Control and Talent Investments
Process enhancements—centralized procurement, project controls, and leadership additions—are designed to strengthen cost visibility and execution discipline. The recent appointment of a new COO and ongoing investments in technology and talent are intended to support scalability and risk management as project volume increases.
5. Collaborative Contracting and Risk Management
Shimmick is advancing its shift toward collaborative contracting models, including progressive design-build contracts, to engage earlier in project lifecycles and balance risk. These models support higher-margin, lower-risk work and deepen client relationships, as evidenced by recent awards with California Water Service.
Key Considerations
This quarter marks a turning point for Shimmick, as the business exits legacy drag and leans into a more disciplined, margin-focused growth model. Investors should weigh the following:
Key Considerations:
- Backlog Visibility Extends Through 2028: Average project duration of 2.5 years and growing backlog support multi-year revenue confidence.
- Margin Expansion Catalysts: Higher-margin projects and exit from non-core work set up sustained gross margin improvement.
- Data Center Exposure as Emerging Tailwind: Specialty electrical and mechanical capabilities align with surging demand for data center infrastructure.
- Execution Risk Moderation: New operational controls and leadership hires aim to reduce project risk and improve consistency.
- Cash Flow Inflection Expected: Wind-down of legacy projects and ramping of new awards should bolster cash generation through 2026.
Risks
Execution risk remains inherent in large-scale infrastructure projects, including potential for schedule delays, cost overruns, and weather disruptions. The wind-down of non-core projects reduces legacy exposure, but any setbacks in major new project ramp-ups or unexpected client disputes (such as the Chickamauga Lock Replacement) could impact revenue timing and margin realization. Commodity inflation and labor market tightness are being priced into new bids, but persistent input volatility could pressure margins if not fully offset.
Forward Outlook
For Q2 and Q3 2026, Shimmick guided to:
- Sequential revenue and margin improvement as new projects ramp through the summer months.
- Continued high bidding activity, with $600 million to $1 billion in monthly pipeline volume.
For full-year 2026, management reaffirmed guidance:
- Consolidated revenue growth of 12% to 22% year-over-year, with $550 million to $600 million in work put in place.
- Adjusted EBITDA expected to increase 200% to 500% year-over-year, targeting $15 million to $30 million.
Management highlighted several factors that support the outlook:
- High-quality backlog and strong win rates underpin revenue visibility.
- Margin expansion expected as project mix shifts and operational initiatives take hold.
Takeaways
Shimmick’s Q1 results validate its strategic pivot, with backlog and margin momentum setting the stage for multi-year growth.
- Backlog and Book-to-Burn Surge: Record backlog and a 2.6 book-to-burn ratio anchor revenue visibility and selective bidding discipline for 2026–2028.
- Margin Expansion Realized: Core gross margins rose to 11% as legacy drag faded, with management targeting further gains as high-quality projects ramp.
