Mayville Engineering Company, Inc.: what insiders have been doing
This page follows insider dealings at Mayville Engineering Company, Inc. as filed with SEC (Form 4), a company from the Industry sector. Between 22 October 2025 and 22 October 2026, 11 insiders published 34 filings.
No insider bought on the market over the period, while 4 insiders filed 8 sales totalling €1.0M. At €283k, the sale published on 7 August 2026 by Leuba Sean P is the largest of the period (0.074% of market cap).
Across the 2,023 companies tracked on its exchange, the median is 41 filings; at 34 filings, this issuer sits below that mark. Over the whole record (from 2019), the tally stands at 48 purchases and 15 sales. The 10-K for the year ended 31 December 2025 shows 546.5 m USD of revenue and -8.1 m USD of net income.
The median gap between a trade and its publication by SEC (Form 4) is 2 days. For comparison, the SEC allows two business days to file a Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify.

About Mayville Engineering Company, Inc.
Mayville Engineering Company, Inc. (NYSE: MEC) is a U.S.-based industrial manufacturing company focused on value-added solutions for original equipment manufacturers (OEMs). Headquartered in Milwaukee, Wisconsin, in the United States, the company was founded in 1945 and has evolved into a Tier I supplier to leading customers across multiple end markets. Its operating model is built around an integrated manufacturing platform that spans product development support, prototyping, tooling, fabrication, coating, assembly, and selected aftermarket services, giving MEC exposure to a large portion of the product lifecycle.
From a business-line perspective, MEC serves a diversified mix of end markets, including heavy- and medium-duty commercial vehicles, construction and access equipment, powersports, agriculture, military applications, and increasingly datacenter & critical power. This diversification is a central part of the investment case, as it reduces reliance on any single industry cycle. The company emphasizes long-standing OEM relationships and the ability to support multiple platforms through broad engineering and manufacturing capabilities.

Geographically, MEC’s footprint is primarily in the United States, with operations spread across several states, including Arkansas, Michigan, Mississippi, Ohio, Pennsylvania, Virginia, and Wisconsin. The company has stated that it operates more than twenty facilities nationwide, which supports customer proximity, logistics efficiency, and regional manufacturing resilience. Its strategy is framed around being a “one-source solution” for customers, combining engineering, production, and end-of-line support.
In competitive terms, MEC positions itself as a leading supply-chain partner for U.S. OEMs in engineered metal components and fabricated assemblies. It also highlights that it has been named the largest fabricator in the United States by Fabricator Magazine for 15 consecutive years, a recognition that supports brand credibility and sector standing. The business remains exposed to pricing pressure, raw-material costs, and cyclical industrial demand, but its scale and breadth of capabilities are important differentiators.
Recent developments have been constructive. MEC released first-quarter 2026 results in early May 2026 and specifically noted continued momentum in its Datacenter & Critical Power end market. In 2025, the company completed the acquisition of Accu-Fab, a move designed to expand its commercial reach and accelerate entry into attractive new markets within its MBX value-creation framework. For investors, MEC represents a U.S.-listed industrial name on NYSE with a diversified customer base, a domestic manufacturing footprint, and a strategy centered on engineered fabrication, operational excellence, and selective growth through acquisition.
