MEC (MEC) Q1 2026: Data Center Revenue Jumps 71%, Unlocking Multi-Year Growth Path
MEC’s Q1 highlighted a decisive pivot toward high-growth data center and critical power markets, with 71% YoY organic growth in that segment offsetting persistent legacy end-market softness. Margins remain pressured by launch costs and underutilized legacy capacity, but management’s commentary and new customer wins signal a durable, multi-year expansion opportunity as data center penetration remains below 5% for top OEMs. Investors should watch for margin inflection and capacity investments as MEC balances legacy commitments with accelerating demand in next-gen infrastructure.
Summary
- Data Center Acceleration: New program launches and customer wins drove robust growth, reshaping MEC’s revenue mix.
- Legacy Markets Still Soft: Commercial vehicle and power sports remain cyclical drags, delaying broad-based recovery.
- Capacity and Margin Watch: Margin rebound and capital allocation discipline will be key as data center ramps continue.
Business Overview
Mayville Engineering Company (MEC) is a leading contract metal fabricator serving OEMs across commercial vehicle, construction, agriculture, power sports, and increasingly, data center and critical power markets. MEC generates revenue by fabricating complex metal components and assemblies for large manufacturers, with major segments now including legacy industrials (commercial vehicle, construction, ag, power sports) and a fast-growing data center and critical power vertical. The business model is anchored in long-term supply relationships, with recent growth driven by program launches and cross-selling synergies from the AccuFab acquisition.
Performance Analysis
MEC delivered 6.8% total sales growth in Q1, but this headline belies a significant shift beneath the surface. The organic core business declined 8.2% YoY, reflecting continued weakness in legacy end markets, especially commercial vehicles (down 24%) and ongoing project-driven volatility in power sports. However, data center and critical power revenue soared 71% YoY, now approaching 20% of total company sales and projected to surpass this threshold by year-end.
Margin pressure persisted, with manufacturing margin falling to 7.6% from 11.3% a year prior, primarily due to $1.2 million in launch costs and low legacy volumes. Adjusted EBITDA margin halved to 4.5%. Free cash flow was negative as investments ramped to support data center launches and capacity retooling, while net leverage climbed to 4.4x post-AccuFab acquisition. SG&A expense rose modestly, reflecting incremental costs tied to AccuFab integration.
- Data Center and Critical Power Surge: This segment’s organic growth outpaced all others, with a $50M+ pipeline of new awards fueling future visibility.
- Legacy Segment Drag: Commercial vehicle and power sports remain in cyclical downturn, offsetting growth elsewhere.
- Margin Compression from Launch Costs: Temporary pressure expected to abate as new programs reach full production run rates in Q2/Q3.
Execution on program launches and cross-selling remains the key bridge to margin normalization, as MEC’s end-market mix shifts toward higher-margin, secularly growing infrastructure verticals.
Executive Commentary
"Our first quarter results exceeded our expectations, driven by strong top-line momentum in our data center and critical power end market. At the same time, the first quarter reflected an ongoing transition across the business. Our teams remained focused on positioning resources, completing tooling requirements, and preparing for the launch of numerous data center and critical power programs throughout 2026."
Jag Reddy, President and CEO
"As production levels increase and utilization improves, we expect better absorption, stronger margin conversion, and improved cash generation over the remainder of the year. With continued working capital discipline, and targeted capital spending, we believe we are positioned to support growth while also making measurable progress on deleveraging."
Rachelle Lair, Chief Financial Officer
Strategic Positioning
1. Data Center and Critical Power: Multi-Year Growth Engine
MEC’s data center and critical power business is now the company’s primary growth vector, with organic revenue up 71% YoY and a qualified pipeline exceeding $125 million. Penetration with top ten OEM customers remains below 5%, signaling vast white space for expansion. Recent wins include two new customers and $50 million in Q1 awards, with most contracts structured as long-running programs rather than one-off projects.
2. Legacy Market Management: Balancing Cycles and Capacity
While commercial vehicle and power sports remain cyclical headwinds, MEC continues to support legacy customers and secure new wins in military and commercial vehicle platforms. The company is actively reallocating capacity—retooling six to seven plants for data center work—while maintaining flexibility to support a legacy recovery if it materializes in late 2026 or 2027.
3. Capital Allocation and Capacity Expansion
Capital deployment is tightly focused on supporting data center launches and selective capacity additions, especially as certain regions (notably the eastern seaboard) approach utilization limits. Management targets a long-term net leverage ratio of 2.5x and expects to increase growth capex above the historical $5–10 million range to address data center demand, while keeping balance sheet discipline front and center.
4. Margin Rebound and Operating Leverage
Launch costs and underutilized legacy assets weighed on Q1 margins, but as data center programs move to full production, management expects a sequential margin recovery, with a clear path to 15%+ long-term EBITDA margins as mix tilts toward higher-margin infrastructure work.
Key Considerations
This quarter marks a structural inflection for MEC, as the company transitions from legacy industrial cyclicality to secular growth in digital infrastructure. Execution risks remain, but the opportunity set is expanding rapidly.
Key Considerations:
- Secular Demand Tailwind: Data center and critical power OEMs are shifting to outsourced fabrication, creating a durable growth runway for MEC.
- Capacity Constraints Emerging: Management flagged $850 million as the practical revenue ceiling on current assets, with some plants now running 24/5 or 7 days per week.
- Margin Inflection Timing: Investors should monitor when launch costs subside and new programs achieve full run-rate, as this will drive EBITDA recovery.
- Legacy Market Optionality: MEC is retaining the flexibility to support legacy OEMs if cyclical upturns materialize, but is not dependent on their recovery for growth.
- Balance Sheet Leverage: Elevated net leverage (4.4x) is a near-term watchpoint, but management expects deleveraging as cash flow improves in the second half.
Risks
Execution risk is elevated as MEC scales multiple data center programs simultaneously, while maintaining legacy customer support. Margin recovery is contingent on smooth program launches and asset utilization. Any delays in data center ramp or further legacy market declines could pressure both cash flow and leverage, especially as growth capex rises. Macro factors—such as tariff changes and commodity price swings—remain secondary but could affect input costs and customer demand.
Forward Outlook
For Q2, MEC guided to:
- Net sales of $145 million to $155 million
- Adjusted EBITDA of $10 million to $13 million
For full-year 2026, management raised the low end and maintained the high end of guidance:
- Net sales of $590 million to $620 million
- Adjusted EBITDA of $52 million to $60 million
- Free cash flow of $25 million to $35 million
Management expects:
- Margin improvement as data center programs reach full production in Q2/Q3, with launch costs waning and operating leverage improving.
- Legacy end-market recovery (notably commercial vehicles) remains a second-half or 2027 story, with minimal contribution expected near-term.
Takeaways
MEC’s Q1 sets the stage for a secular pivot toward high-growth, high-margin infrastructure markets, but near-term margin and leverage headwinds require disciplined execution and careful capital allocation.
- Data Center Momentum: New customer wins and robust pipeline reinforce multi-year revenue visibility, with penetration rates still in early innings.
- Margin Recovery Hinges on Execution: As launch costs abate and utilization climbs, expect margin normalization and improved cash conversion.
- Capacity Expansion and Capital Discipline: Investors should track how MEC balances growth investment with deleveraging as demand outpaces legacy asset base.
Conclusion
MEC’s business mix is undergoing a structural shift, with data center and critical power now the primary growth lever. Margin and cash flow inflection depend on flawless execution and timely capacity investments. Investors should watch for signs of sustainable margin rebound and further customer penetration as the secular infrastructure cycle accelerates.
Industry Read-Through
MEC’s results underscore the accelerating outsourcing trend among data center and critical power OEMs, a secular tailwind benefitting large, flexible fabricators. Capacity constraints and the need for rapid, adaptable supply chains are emerging as key competitive differentiators, with suppliers able to retool and scale quickly gaining share. Legacy industrials remain cyclical and project-driven, but the shift toward digital infrastructure is increasingly the dominant force across the contract manufacturing landscape. Peers with exposure to data center build-out and a scalable manufacturing footprint are best positioned to capitalize on this multi-year demand surge.
