The LGL Group, Inc. is a holding company engaged in services, merchant investment and manufacturing business activities. It operates primarily in the precision engineering, manufacturing and services sectors, having acquired and managed numerous businesses since 1985.

The company generates revenue through two main activities. Its Electronic Instruments segment sells high performance frequency and time reference standards and related products such as distribution amplifiers and redundancy switches to customers in telecommunications, satellite communications, electric utilities and other technical markets. Its Merchant Investment segment earns income from investment returns, gains and losses on securities and fees from syndicated investment vehicles.

The company operates through the following segments: Electronic Instruments and Merchant Investment.

• Electronic Instruments: The Electronic Instruments segment is operated through wholly owned subsidiary Precise Time and Frequency LLC PTF a globally positioned producer of industrial electronic instruments and commercial products and services. Founded in 2002 PTF operates from its design and manufacturing facility in Wakefield Massachusetts. It focuses on the design and manufacture of high performance frequency and time reference standards for timing and synchronization in applications such as satellite communication, time transfer systems, network synchronization, electricity distribution and metrology. The segment offers customers frequency reference and time standard synchronization solutions tailored to performance requirements. It has developed a comprehensive portfolio of time and frequency instrumentation including frequency standards, time standards and time code generators complemented by ancillary products such as RF distribution amplifiers, digital distribution amplifiers, time code distribution amplifiers and redundancy switches. Thousands of instruments have been delivered worldwide for uses ranging from simple network time servers to complex satellite communications and broadcast systems. Military applications include synchronization of mobile satcom terminals, high performance sources for calibration and test equipment providing ultimate frequency stability and phase noise performance.

• Merchant Investment: The Merchant Investment segment comprises various investment vehicles in which the company has a shareholder partner or general partner interest through which it invests its capital. It seeks to identify and acquire undervalued assets and businesses often through the purchase of securities and to increase value via management financial or operational changes while managing complex legal regulatory or financial issues. As a shareholder or partner the company provides advisory and certain administrative and back office services to these investment vehicles but not to other entities. As of December 31 2025 the company held investments with a fair value of $41,353 of which $25,655 was allocated to the Merchant Investment business. Marketable securities are accounted for under FASB ASC Topic 321 Investments Equity Securities and are reported at fair value on the consolidated balance sheets. The segment also uses special purpose vehicles such as LGL Systems to sponsor investments raise external capital and earn management fees and success based incentives.

The company holds a niche position in the precision timing and frequency market where it competes with several domestic and international manufacturers that offer similar high performance products. Its advantage lies in engineering expertise that enables custom configurations and reliable performance for demanding applications such as satellite communications and network synchronization. In the Merchant Investment arena the company follows a value oriented approach inspired by Graham and Dodd principles seeking undervalued assets and adding value through active management and operational improvements. This strategy combined with its ability to sponsor special purpose vehicles and raise external capital gives it a flexible platform for long term investment.

The company serves a diverse range of original equipment manufacturers and end users in telecommunications, satellite communications, electric utilities, broadcasting and related technical fields. In 2025 the top four customers accounted for approximately 54 percent of total sales while the remaining revenue was spread across roughly 32 other accounts.
