Mayville Engineering

MEC helps big brands make parts for trucks, tractors, and data centers. The company builds everything from metal frames to complex assemblies for major manufacturers. This work takes a product from an initial idea to a finished component.

From Metal Sheets to Machine Parts

• Metal Fabrication: Creating custom parts through laser cutting, stamping, and tube bending for heavy machinery and vehicles.
• Aluminum Extrusion: Shaping aluminum into specific profiles using high-pressure presses for various industrial applications.
• Custom Coatings: Applying protective finishes like chemical agent resistant coating to parts used in military and industrial settings.
• Product Assembly: Combining multiple manufactured parts into finished components or sub-assemblies for original equipment manufacturers.

Strategic Moves and Market Shifts

• Acquired Accu-Fab, LLC in 2025 to increase presence in the data center and critical power markets.
• Implemented the MEC Business Excellence (MBX) framework in 2022 to focus on lean manufacturing and operational efficiency.
• Invested in fiber laser systems and robotic brake presses to automate production and reduce manual labor costs.
• Expanded its relationship with John Deere to cover over 65 model platforms across five market segments.

What Makes MEC Different?

MEC manages costs by using contracts that pass through changes in steel and aluminum prices to customers. The company maintains stability through broad market exposure, ensuring no single end market accounts for more than 32% of net sales.

The Latest Financial Results

• Net sales grew 6.8% to $144.8 million in Q1 2026, up from $135.6 million in Q1 2025.
• Net income fell to a loss of $8.2 million in Q1 2026, worsening from a $20,000 profit in the prior year.
• Major customers PACCAR Inc. and John Deere accounted for 13.6% and 10% of net sales respectively in 2025.
• Free cash flow reached $10.2 million for the period ending December 31, 2025.

Bottom Line

MEC has evolved from a local shop into the largest metal fabricator in the United States for 15 consecutive years. Its shift toward data center infrastructure reflects a strategy of diversifying beyond traditional heavy machinery markets.
