LGL GROUP INC (LGL) stock intrinsic value fair value estimate & owner earnings analysis

The LGL Group is a small holding company. Since spinning off its main frequency-control business, M-tron Industries, to shareholders in October 2022, it has owned one operating business, Precise Time and Frequency (PTF) of Wakefield, Massachusetts, which makes GNSS timing receivers and time-and-frequency distribution equipment for defense, aerospace, satellite and communications customers with seven manufacturing and engineering staff. It also has an investment arm (Lynch Capital International) and a small corporate office. Almost all of the value is cash. The company held about $45.2 million in cash and Treasury money-market funds at June 30, 2026, and a rights offering that closed July 23, 2026 added 6,062,714 shares at $6.90 (about $41.8 million gross), taking cash to about $86 million and shares outstanding to 12,613,149. There is no debt. Outside investors in two partly owned investment vehicles (LGL Systems and the new Skyline vehicle) own $3.2 million of the consolidated equity, which we deduct. That leaves about $82.8 million, or $6.56 a share, for shareholders. The real question is what that cash is worth to shareholders once the cost of running the company is counted. PTF earned $296,000 before tax in 2025 on $2.45 million of sales at a 53% gross margin. Corporate and investment-arm expenses were about $1.76 million, though. Leaving out interest on the cash, the company lost about $1.4 million a year before tax in 2024 and 2025. Costs rose in the first half of 2026. Overhead excluding stock awards ran at roughly $2.5 million a year, and stock awards granted in January and May 2026 cost $848,000 in six months (about $160,000 in the second quarter alone). Owner earnings since the spin-off were $37,000 in 2023, $604,000 in 2024 and $78,000 in 2025, and all of that came from interest on the cash. We count the cash once, at face value, so we do not count its interest again as earnings. We also left out a one-time, non-cash $648,000 tax reversal in 2025 and treated stock awards as a real cost. Years before 2023 include M-tron and describe a different company, so we did not use them. PTF's near-term growth is secured. Its order backlog rose from $625,000 at the end of 2025 to $3.63 million at June 30, 2026. On August 5, 2026 PTF announced about $6 million of awards from an existing customer building a low-earth-orbit satellite network, part of which was already in the June backlog. Together that is more than two years of 2025 sales. We credit this backlog. We do not credit follow-on orders that have not been announced in the base case. We also give nothing for the planned investments in defense technology, precision timing, smart agriculture and resilient infrastructure, because no targets have been named. New capital is assumed to earn only a fair return. Base case: PTF earns about $0.8 million before tax in the first year and $0.6 million in the second as the backlog ships, then settles near its 2025 level of about $0.3 million. Corporate costs, including stock awards, run about $2.9 million a year indefinitely and are deductible against the company's investment income. The cash earns only Treasury yields of about 3.6% for two more years before it is put to work. The operating side is worth about minus $33.7 million after tax, and the idle period costs about $2.9 million. Against $82.8 million of cash the company owes nothing to lenders, so shareholders' value is about $46.2 million, or $3.67 a share. Bear case: overhead stays at the higher 2026 pace of about $3.4 million a year including stock awards. PTF's profit fades to about $150,000 a year once the backlog ships, since its three largest customers made up 45% of 2025 sales. The cash sits in Treasuries for five more years, as most of it has since 2022. Shareholders' value is about $32.8 million, or $2.60 a share, with no borrowings to subtract. Bull case: the satellite customer keeps ordering at about the 2026 pace, so PTF earns about $0.6 million a year after the backlog. Overhead moves back toward the 2025 level, at about $2.3 million including stock awards, and the cash is invested within a year at a fair return. Shareholders' value is about $59.4 million, or $4.71 a share, again with no borrowings. Our previous estimate ($6.15 to $7.63 a share) counted the cash at face value and added PTF, but it did not charge the ongoing cost of running the holding company. Charging that cost, which ran $1.6 to $1.8 million a year in 2024 and 2025 and rose in 2026, is the main reason the estimate is lower. The much larger, secured PTF backlog partly offsets it. The estimate would be too low if management invests the $86 million in businesses earning well above 6%, or cuts overhead. Its 2019 sponsorship of the IronNet SPAC turned a $3.35 million stake into roughly $13 million of net pre-tax gains, even after giving back much of the peak gain. The estimate would be too high if the company makes a large acquisition at a full price or keeps raising corporate costs and share grants.
