About Twin Disc, Incorporated

Twin Disc, Incorporated, doing business as Twin Disc Mid-Atlantic, manufactures precision power transmission and mechanical components—clutches, friction plates, torque converters, hydraulic assemblies, bearings, valves, and related parts—for the U.S. Department of Defense as a prime contractor (100% of awards). The Racine, Wisconsin-based company competes predominantly full-and-open on purchase orders and delivery orders; a small number of awards carry Total Small Business set-aside designations, but the bulk of Twin Disc's footprint is unrestricted competitive work. Twin Disc operates as a parent company with three named subsidiaries: Twin Disc Southeast, Inc. (self-certified small disadvantaged business), Mill-Log Equipment Co, Inc., and Mill-Log Marine Inc.

Twin Disc's federal contracting profile is dominated by transactional component procurement from the Defense Logistics Agency. Over the past five years, the company has received roughly 228 awards annually, with 1,430 total awards in the source portfolio and $100 million in combined potential value. Award volume declined from 77 in 2022 to 49 in 2023, stabilized at 51 in 2024 and 2025, with six awards recorded through April 2026. The customer base is tightly concentrated: Defense Logistics Agency Land and Maritime alone accounts for 706 awards (49% of the total count) worth $21.8 million; DLA Aviation brings 153 awards worth $1.9 million. By potential value, however, the Army Contracting Command Detroit Arsenal dominates, with 57 awards anchoring $73 million—driven by a single large delivery order in April 2024 valued at $11.08 million and a modification in September 2024 worth $5.7 million, both for hydraulic transmission components under delivery order contract vehicles.

The vast majority of Twin Disc's work flows through small purchase orders and delivery orders under individual Indefinite Delivery Contracts with DLA Land and Maritime and Aviation. The top five parent vehicles are all single-award IDCs valued at $250,000 each, with IDC SPE4A616D6031 generating 14 task orders worth $95 thousand combined. These vehicles do not represent strategic scale; rather, they reflect the granular, repetitive nature of the business—individual orders for gaskets, O-rings, retaining rings, valve bodies, clutch disks, bearing assemblies, and similar components, typically in the $500 to $50,000 range. Representative awards include a $6.6 million delivery order from Air Force Sustainment Center ACC Warren in March 2026 for 27 power transmission equipment components, a $1.7 million definitive contract from DLA Land and Maritime in February 2023 for 34 hydraulic parts kits, and a $747 thousand definitive contract in August 2022 for hydraulic parts kits.

Twin Disc's capability footprint is grounded entirely in mechanical component manufacturing for military vehicle and equipment maintenance: the top NAICS codes are Motor Vehicle Transmission and Power Train Parts Manufacturing (279 awards), Mechanical Power Transmission Equipment Manufacturing (87 awards), and Gasket, Packing, and Sealing Device Manufacturing (85 awards). Product service code concentration mirrors this: Vehicular Power Transmission Components (520 awards), Power and Hand Pumps (100 awards), and Torque Converters and Speed Changers (71 awards). The company holds no visible presence on government-wide or large-scale IDIQs, GWACs, or agency-wide vehicles; all work is sourced through direct DLA or Army Contracting Command vehicles or individual purchase orders.

As a subcontractor, Twin Disc supplies materials and services on a small number of M88 armored vehicle programs under BAE Systems Land & Armaments L.P., with four sub-awards recorded between March 2024 and September 2025 focused on production modifications and funding for Taiwan Management Office work. Subcontracting activity is minimal and does not materially affect the prime footprint profile.

Twin Disc faces a recompete cliff of $23.5 million in potential value across seven awards completing within the next twenty-four months. The company's position is that of an established component supplier with deep institutional relationships at DLA and Army Contracting Command, competing for renewal of small, commodity-driven contracts under existing procurement channels rather than pursuing strategic vehicles or large integration opportunities.
