TestEquity

TestEquity is a portfolio company of LKCM Headwater Investments, the private equity arm of Luther King Capital Management, a Fort Worth-based investment firm founded by J. Luther King Jr. in 1979. LKCM Headwater acquired TestEquity in 2017 and has since pursued a buy-and-build strategy, adding manufacturing capabilities through bolt-on acquisitions. The firm operates as a standalone entity with its own management team under the LKCM Headwater umbrella.

TestEquity distributes new and used test-and-measurement equipment — oscilloscopes, spectrum analyzers, multimeters, power supplies — from major manufacturers including Keysight, Tektronix, and Fluke. Through acquisitions of GFS Manufacturing and KASKO, the firm also manufactures proprietary products such as sheet metal enclosures and environmental test chambers. End customers include aerospace and defense contractors, US national laboratories, electronics manufacturers, and university engineering departments.

Neither. TestEquity operates as an industrial distribution and manufacturing company. It is a portfolio company of LKCM Headwater Investments, which is a private equity firm managing capital on behalf of institutional and high-net-worth limited partners, but TestEquity itself is an operating business, not a fund or family office.

Acquisition sourcing is driven by the LKCM Headwater team, which identifies complementary manufacturing businesses that can be integrated into TestEquity's distribution platform. The firm targets niche electronic test and measurement product lines, sheet metal fabrication, and enclosure manufacturing — bolt-on companies that can cross-sell through TestEquity's existing customer base. LKCM Headwater typically pursues proprietary, intermediated deals rather than broad auction processes, per its stated investment approach.

The thesis combines distribution margin with manufacturing margin. By owning both the channel to market and a portion of the products sold through that channel, the platform captures margin at two points and builds switching costs with customers who value single-vendor sourcing for test equipment, enclosures, and chambers. The strategy also provides a natural pipeline for add-on acquisitions — small manufacturers gain access to an established distribution network upon acquisition, creating a recurring deal-flow engine at attractive entry multiples.
