MANAGEMENT COMMENTARY

“Our third quarter results were in line with our expectations and reflected strong demand as project volumes continued to accelerate within our Datacenter & Critical Power end market,” said Jag Reddy, President and Chief Executive Officer. “Net sales increased 18.1% year-over-year, driven by continued growth in Datacenter & Critical Power and improving demand across our Commercial Vehicle and Construction & Access end markets. As volumes ramped, Adjusted EBITDA margin improved on a sequential basis through better capacity utilization, while we continued to absorb project launch costs consistent with our expectations. At the same time, operational efficiency across our footprint remained uneven during the quarter as our teams responded to rapidly evolving customer requirements and the pace and volume of incoming demand. We view these dynamics as a natural part of scaling the business through a period of accelerated growth, and our priority remains investing in the people, equipment and capacity required to capture what we believe is a historic, multi-year growth opportunity in the high-value Datacenter & Critical Power space.”

“During the quarter, we secured approximately $45 million of new Datacenter & Critical Power project awards, and our qualified opportunity pipeline now exceeds $200 million,” Reddy continued. “Importantly, this demand we are seeing today reflects datacenter infrastructure investments initiated approximately three years ago, as the products we manufacture are typically installed during the later stages of a project build. Based on our awarded programs and pipeline, we are anticipating reaching full capacity within the next 18 months and have started deploying capital towards expanding our footprint. On October 1, 2026 we closed on the acquisition of our Thomson, Georgia facility, which, together with planned equipment investment, is expected to add approximately $50 million of annual revenue capacity by 2028 and increase our total revenue capacity beyond the approximately $850 million previously disclosed.”

​

“Looking ahead, I am excited about the opportunity in front of us and our ability to deliver profitable growth in 2027 and beyond,” Reddy concluded. “We will continue to incur launch costs and deploy capital in a disciplined manner as we position MEC to serve this growing customer base. While these investments and the ongoing alignment of our operations with customer timelines will remain a factor over the coming quarters, we expect to realize improved operating leverage as volumes continue to ramp. We believe these actions position MEC to deliver attractive, sustainable returns on invested capital as we capitalize on this multi-year secular growth opportunity.”

PERFORMANCE SUMMARY

Net sales increased by 18.1% on a year-over-year basis in the third quarter of 2026, primarily due to growing demand in the Datacenter & Critical Power, Commercial Vehicle, Construction & Access and Other end markets. These increased volumes were partially offset by lower demand in the Powersports and Agriculture end markets.

Manufacturing margin was $18.8 million in the third quarter of 2026, or 11.0% of net sales, versus $15.9 million, or 11.0% of net sales, in the prior year period. The year-over-year increase in manufacturing margin dollars was primarily attributable to improved capacity utilization driven by higher sales volumes in the Datacenter & Critical Power end market, as well as growth within the Commercial Vehicle and Construction & Access end markets. This increase was partially offset by $3.0 million of Datacenter & Critical Power project launch and outsourcing costs, and premium labor.

Bonuses and deferred compensation expenses were $2.5 million in the third quarter of 2026 as compared to $2.2 million in the prior year period. Other selling, general and administrative expenses were $8.8 million in the third quarter of 2026 as compared to $10.5 million in the prior year period. The decrease in other

MANAGEMENT COMMENTARY

“Our second quarter results reflect stronger-than-expected order activity within our Commercial Vehicle end market and continued momentum across our Datacenter & Critical Power end market," said Jag Reddy, President and Chief Executive Officer. "Our execution remained strong as we continued to invest in resources and equipment necessary to support the accelerating customer demand. As volumes increased, margins improved through better capacity utilization, though we continued to absorb project launch costs associated with the ramp up of new Datacenter & Critical Power programs. At the same time, we are making selective decisions to prioritize capacity for higher-value, higher-margin programs that support long-term profitable growth."

"During the quarter, we secured approximately $40 million of new Datacenter & Critical Power project awards as customer demand remained robust," Reddy continued. "Our qualified opportunity pipeline continues to exceed $125 million, supported by strong customer quoting activity. Within our Commercial Vehicle end market, demand trends improved during the quarter, and we expect continued recovery through the remainder of the year, complemented by steady activity in our Construction & Access end market. Reflecting these favorable trends, we are raising our full-year 2026 net sales guidance by approximately 5%."

"We also completed a common stock offering during the quarter, generating approximately $94 million in net proceeds," Reddy concluded. "The proceeds were immediately used to reduce debt and strengthen our balance sheet, increasing our available liquidity to more than $100 million. Given the significant opportunities we continue to see across the Datacenter & Critical Power infrastructure market, we also intend to use a portion of the net proceeds from the offering to invest an incremental $50 million in organic growth initiatives across 2026

​

and 2027 to expand capacity to support higher-value programs. These investments position MEC to deliver attractive, sustainable returns on invested capital as we capitalize on a multi-year secular growth opportunity."

PERFORMANCE SUMMARY

Net sales increased by 23.2% on a year-over-year basis in the second quarter of 2026, primarily due to organic growth in the Datacenter & Critical Power, Commercial Vehicle, and Construction & Access end markets and the impact of the Accu-Fab acquisition completed in the third quarter of 2025. These increases were partially offset by lower demand in the Powersports, Agriculture and Military end markets.

Manufacturing margin was $17.7 million in the second quarter of 2026, or 10.9% of net sales, versus $13.6 million, or 10.3% of net sales, in the prior year period. The year-over-year increase in manufacturing margin was primarily attributable to higher margin sales contribution from the Accu-Fab acquisition and improved capacity utilization as demand in several legacy end markets improved. This increase was partially offset by $2.1 million of project launch costs and higher costs associated with ongoing workforce expansion to support demand.

Bonuses and deferred compensation expense was $4.8 million in the second quarter of 2026 as compared to $1.5 million in the prior year period. Other selling, general and administrative expenses were $9.3 million in the second quarter of 2026 as compared to $10.3 million for the same prior year period. The decrease in other selling, general and administrative expenses primarily reflects non-recurring executive transition expenses and Accu-Fab acquisition-related costs in the prior year period, partially offset by incremental SG&A expenses associated with the acquisition.

Interest expense was $3.5 million in the second quarter of 2026, as compared to $1.4 million in the prior year period, due to increased average borrowings and interest rate under the Company’s revolving credit facility and the timing of debt
