Limbach Holdings, Inc.

As of December 31, 2025, the Company leases several properties, consisting of offices, warehouses, fabrication and supply shops within the Eastern and Midwestern regions of the United States. Generally, these leases range from five to ten years and are on terms the Company believes to be commercially reasonable. A majority of these premises are leased from individuals or entities with whom the Company has no other business relationship. In certain instances, the Company leases property from entities associated with former employees who became part of the Company through acquisitions.

The Company’s leased premises range in size from approximately 1,000 square feet to 150,000 square feet. To maximize available capital, the Company generally intends to keep leasing its properties, however, the Company may also consider purchasing a property where it believes ownership would be more economical. The Company utilizes substantially all of its leased property and believes there will be no difficulty either in negotiating the renewal of such leases as they expire or finding alternative space, if necessary.

In addition to its leased facilities, as a result of the Company’s acquisition of Pioneer Power during 2025, the Company now owns an approximate 40,000 square foot facility located in Woodbury, Minnesota that is used for operations, fabrication, warehousing and general office purposes.
