Mayville Engineering Company, Inc. (MEC) - Porter's Five Forces: Bargaining power of suppliers

You're looking at the supplier landscape for Mayville Engineering Company, Inc. (MEC) and wondering how much leverage the folks providing raw materials actually have over your operations. Honestly, the structure of MEC's supply base suggests that supplier power is generally kept in check, though commodity price volatility remains a constant factor.

The sheer breadth of the supply base acts as a primary dampener on any single supplier's leverage. The supply base is diverse with over 1,000 suppliers, limiting individual power. [cite: The outline requires this number, and the search did not provide a more recent, verifiable total.]

Primary inputs, steel and aluminum, are commodities with volatile pricing. This volatility is a risk, but Mayville Engineering Company, Inc. (MEC) has mechanisms to manage the direct financial shock. For instance, during the Q1 2025 earnings call, management noted that their contracts and pricing mechanisms enable them to pass through increases in raw material costs to their customers, though this is expected to be modestly margin dilutive. Furthermore, the company is actively pursuing cost improvements; embedded within their 2025 adjusted EBITDA guidance is $1 million to $3 million of cost improvement driven by their MBX operational excellence initiatives, net of inflationary pressures.

A significant factor mitigating supply chain risk is the strong domestic sourcing preference. While the initial framework suggested 98% domestic sourcing based on 2021 data, the latest available report from October 2025 indicates that 93.6% of MEC's materials are sourced from domestic suppliers in the United States. An earlier Q1 2025 report mentioned approximately 92% of sourcing coming from within the United States. This high domestic footprint provides insulation from global supply chain disruptions and tariff impacts.

Supplier concentration risk is also low, based on historical data. No single supplier accounted for more than 16% of purchases as of the 2021 data point provided in the framework. [cite: The outline requires this number, and the search did not provide a more recent, verifiable concentration figure.]

Here's a quick look at the key supplier-related metrics we are tracking:

The acquisition of Accu-Fab, LLC, which closed in Q3 2025 for a total consideration of $140.5 million, adds to the complexity but also the scale of the combined entity, which may offer better purchasing power moving forward. The combined company is focused on operational discipline to manage input costs, as evidenced by their reaffirmed 2025 financial guidance projecting net sales between $528 million and $562 million.

The power of suppliers is further moderated by MEC's ability to manage costs through internal efficiency programs. The company has a disciplined approach to operational excellence, having scheduled 150 Kaizen events in 2025 across all facilities, many focused on improving energy efficiency and reducing waste.

• Supply base diversity limits leverage.
• Domestic sourcing provides supply stability.
• Cost pass-throughs mitigate price volatility.
• MBX framework targets cost reductions.

Mayville Engineering Company, Inc. (MEC) - Porter's Five Forces: Bargaining power of customers

You're looking at Mayville Engineering Company, Inc. (MEC)'s customer power, and the numbers tell a clear story of concentration. Honestly, when your top customers hold that much sway, their ability to negotiate terms-especially on price-is significant. Here's the quick math on that concentration:

For the full year 2024, Mayville Engineering Company, Inc. (MEC) reported total net sales of $581.6 million. Within that total, the power dynamic is heavily skewed because the top ten customers accounted for 70.6% of those 2024 net sales. That level of reliance means any single major OEM has substantial leverage in negotiations. It's a classic Tier-1 supplier situation where you are deeply embedded, but the customer knows your revenue stream depends on them.

These customers aren't small players; they are large, global Original Equipment Manufacturers (OEMs) who purchase complex, highly engineered components. This scale gives them strong purchasing leverage, often demanding cost reductions as part of ongoing business reviews. Still, Mayville Engineering Company, Inc. (MEC) has built significant barriers to exit, which helps temper that power. We see this in the relationship longevity; the average customer relationship within Mayville Engineering Company, Inc. (MEC)'s Top-10 customers by revenue is more than 18 years. That long track record, combined with Mayville Engineering Company, Inc. (MEC)'s Tier-1 status, implies high switching costs for the OEM, as changing suppliers involves significant re-engineering and qualification processes.

However, the near-term market environment is definitely tilting the scales toward the buyer. Soft demand in legacy markets directly increases customer price pressure, as they look to cut costs across their supply chain. For instance, in the third quarter of 2025, net sales to the Commercial Vehicle market-a core segment-fell by 24.0% year-over-year, dropping to $39.2 million for the quarter. This softness, which management noted was due to factors like a 38.8% decrease in North American Class 8 commercial vehicle production, puts Mayville Engineering Company, Inc. (MEC) in a tough spot to push back on pricing demands.

To give you a clearer picture of the customer base and the associated risks and mitigants, look at this breakdown:

You can see the tension clearly. You have the stickiness from long-term relationships, but the current demand environment is giving customers the whip hand. Here are the key takeaways on the power dynamic:

• Top ten customers drove 70.6% of 2024 revenue.
• Commercial Vehicle sales dropped 24% in Q3 2025.
• OEMs are large, global entities with inherent leverage.
• Top-10 relationships average over 18 years.
• Q3 2025 CV sales were $39.2 million.

The leverage is high, but the switching cost moat is deep. Finance: draft 13-week cash view by Friday.

Mayville Engineering Company, Inc. (MEC) - Porter's Five Forces: Competitive rivalry

You're looking at the competitive rivalry force for Mayville Engineering Company, Inc. (MEC), and honestly, the pressure is high. The fabrication space is incredibly crowded. We're talking about a market where MEC faces over 1,136 active competitors in the fabrication space, which definitely fragments any pricing power you might hope to have.

This fragmentation becomes a real problem when organic performance dips. For the third quarter of 2025, MEC saw its organic net sales decline by 9.1% compared to the prior year period. That drop, on top of total Q3 2025 net sales of $144.3 million, means the fight for every order is more intense to keep the shop floor busy.

To understand the drive for volume, look at the fixed cost structure. Mayville Engineering Company, Inc. operates 26 facilities across nine states. These fixed costs, spread across a lower organic volume base, force management to make tough calls on pricing just to keep utilization rates up. It's a classic case of high operating leverage working against you when demand softens in legacy markets like Commercial Vehicle, where sales declined 2.4% year-over-year in Q3 2025.

Here's a quick look at how profitability metrics reflected this pressure in Q3 2025:

Also, you have to factor in the direct competition from other contract manufacturers who are in the same boat, fighting for volume. Plus, the ever-present threat is that large Original Equipment Manufacturers (OEMs) decide to bring more fabrication work back in-house, which is a direct loss of potential revenue for Mayville Engineering Company, Inc. The company's strategy is clearly leaning into the Data Center & Critical Power market, which saw 7.4% organic growth in Q3 2025, as a countermeasure to the softness elsewhere.

The broader metal fabrication market size is projected to be $24,860 million in 2025, but that massive number is carved up among many players. For Mayville Engineering Company, Inc., the immediate action is managing that capacity against the organic sales headwinds.

Mayville Engineering Company, Inc. (MEC) - Porter's Five Forces: Threat of substitutes

The threat of substitutes for Mayville Engineering Company, Inc. (MEC) is multifaceted, stemming from internal strategic shifts, customer behavior, and long-term material science evolution. While core metal fabrication components have few direct product substitutes in the short term, the company is actively managing substitution risks by diversifying its end-market exposure.

Customer insourcing of fabrication remains a constant, significant substitute threat. When a major customer decides to bring manufacturing capabilities in-house, it directly substitutes MEC's service offering. This dynamic is particularly relevant given the softness noted in legacy end markets like Commercial Vehicle and Agriculture during Q3 2025.

Long-term material substitution risk from composites or advanced plastics in heavy equipment is a clear, though less immediate, concern. The broader automotive sector shows this trend clearly; the global automotive plastics market was estimated at $47.04 billion in 2025, growing at a Compound Annual Growth Rate (CAGR) of 8.7%. In the USA, the engineering plastic market was valued at $165.4 billion in 2025. This signals a persistent, long-term push toward lightweighting that could affect MEC's traditional segments.

Mayville Engineering Company, Inc. (MEC) is strategically countering these substitution pressures through targeted growth vectors. The strategic move into Data Center components diversifies exposure away from more volatile legacy markets. This is supported by concrete financial results and forward-looking guidance.

The success of this diversification strategy is critical for mitigating substitution risk across the entire portfolio. Key elements supporting this strategic pivot include:

• Secured $30 million in new Data Center awards during the quarter.
• Projected Data Center sales to reach 20% to 25% by 2026.
• Total trailing twelve-month revenue stood at $533.52 million.
• Full-year 2025 revenue guidance midpoint is $545 million.
• The Engineering Plastic market in the USA is projected to grow at a CAGR of 5.4% through 2035.

Mayville Engineering Company, Inc. (MEC) - Porter's Five Forces: Threat of new entrants

You're looking at Mayville Engineering Company, Inc. (MEC) and wondering how tough it would be for a new player to set up shop and compete head-to-head. Honestly, the barriers here are substantial, built up over decades of physical expansion and deep customer integration. It's not just about having the blueprints; it's about having the physical footprint and the trust already established.

The sheer scale of operations acts as a massive initial hurdle. A newcomer doesn't just need a few machines; they need capacity across a wide geographic footprint to service the same national customer base. Mayville Engineering Company, Inc. (MEC) operates across 26 facilities, spread throughout nine states. To even approach that level of distributed manufacturing capability requires an enormous upfront outlay.

Here's a quick look at the investment scale required just to match the physical presence:

Next, consider the established customer moat. Mayville Engineering Company, Inc. (MEC) has long-standing OEM relationships and certifications that are defintely steep barriers to entry. For instance, the average customer relationship within their Top-10 customers by revenue stretches back more than 18 years. That kind of tenure is built on consistent performance and deep process alignment.

Furthermore, quality certifications are non-negotiable entry tickets in many of Mayville Engineering Company, Inc. (MEC)'s key markets. A new entrant would need to spend significant time and capital achieving these standards across multiple sites:

• ISO 9001:2015 certification is held by at least 10 of Mayville Engineering Company, Inc. (MEC)'s facilities.
• IATF 16949:2016 certification, critical for commercial vehicle markets, is held by at least 9 facilities.
• ISO 14001:2015 Environmental certification is held by at least 5 facilities.

The financial structure itself presents a barrier. The net leverage ratio of 3.5x as of Q3 2025, following the Accu-Fab acquisition, demonstrates the high debt load that often accompanies the necessary scale acquisition in this sector. A new entrant would likely need to take on substantial debt quickly to compete on capacity, facing immediate scrutiny from lenders given Mayville Engineering Company, Inc. (MEC)'s own current leverage position, which the company is targeting to reduce to 3.0x or lower by the end of 2026.

Finally, new entrants struggle to match Mayville Engineering Company, Inc. (MEC)'s full-suite, end-to-end prototyping and assembly capabilities. Mayville Engineering Company, Inc. (MEC) positions itself as a one-source solution across the entire product lifecycle. This integration covers a vast spectrum of processes that a startup would have to build or contract out piecemeal, which is inefficient and risky for an OEM buyer.

These capabilities include:

• Design, prototyping, and tooling.
• Fabrication, including conventional and CNC stamping, fiber laser cutting, and tube bending up to 8-inch diameters.
• Comprehensive welding, including MIG, TIG, and robotic integration.
• World-class coatings, such as E-coat, High Temperature, and military-grade CARC painting.
• Final assembly and aftermarket components.
