Limbach Holdings to Buy 1901 Inc. for $63 Million
The building systems firm said the all-cash deal will create its largest electrical operation and deepen Midwest scale.
Limbach Holdings, Inc. (LMB) agreed to acquire 1901 Inc. for $63 million in cash, subject to customary post-closing adjustments.
The building systems solutions firm said the purchase will increase its scale in the Midwest and establish the company’s largest electrical operation to date. The deal also adds capabilities across mechanical, plumbing, controls, fabrication, service, and underground utility solutions.
Michael McCann, President and Chief Executive Officer of Limbach, stated, “1901 is an exceptional fit with Limbach’s strategy and represents another important step in scaling our building systems solutions platform. Both companies were founded in 1901 and share a long history of technical expertise, strong customer relationships, and a commitment to quality.”
Limbach is a building systems solutions firm that designs, delivers, and maintains mechanical, electrical, plumbing, and controls systems for mission-critical facilities. As of May 2026, the company had approximately 1,600 team members across 21 offices in the Eastern and Midwestern United States.
The $63 million purchase follows a pattern of Midwest-focused bolt-ons. In July 2025, Limbach closed the acquisition of Pioneer Power, Inc. for $66.1 million at closing, financed with available cash and borrowings under an expanded revolving credit facility. Pioneer Power, an industrial and institutional mechanical solutions provider in the Greater Twin Cities and Upper Midwest, was expected to contribute annualized revenue of about $120 million and Adjusted EBITDA of about $10 million beginning in 2026.
Earlier, in December 2024, Limbach paid $23 million at closing for Consolidated Mechanical, with $2 million in contingent earn-outs. That deal expanded the company’s reach into Kentucky, Illinois, and Michigan and was expected to add annualized revenue of about $23 million and EBITDA of $4 million per annum beginning in 2025.
The 1901 transaction is all-cash and, like those prior deals, is subject to customary working-capital-type adjustments. Limbach did not disclose an expected closing date for 1901 in the announcement.
