1. Basis of Presentation

The LGL Group, Inc. is a holding company engaged in services, merchant investment, and manufacturing business activities. The Company was incorporated in 1928 under the laws of the State of Indiana and reincorporated under the laws of the State of Delaware in 2007. Unless the context indicates otherwise, the terms "LGL," "LGL Group," "we," "us," "our," or the "Company" mean The LGL Group, Inc. and its consolidated subsidiaries.

The Company’s manufacturing business is operated through its subsidiary Precise Time and Frequency, LLC ("PTF"), which has operations in Wakefield, Massachusetts. PTF is engaged in the design of high-performance Frequency and Time Reference Standards that form the basis for timing and synchronization in various applications.

These unaudited Condensed Consolidated Financial Statements do not include all disclosures that are normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") and should be read in conjunction with the audited Consolidated Financial Statements and the related notes included in our Annual Report on Form 10-K for the year ended December 31, 2023 (the "2023 Annual Report") filed with the Securities and Exchange Commission (the "SEC") on April 1, 2024. The consolidated financial information as of December 31, 2023 included herein has been derived from the audited Consolidated Financial Statements in the 2023 Annual Report

The Condensed Consolidated Financial Statements include the accounts of The LGL Group, Inc., its majority-owned subsidiaries, and variable interest entities ("VIEs") of which we are the primary beneficiary.

In the opinion of management, these Condensed Consolidated Financial Statements contain all adjustments (consisting of normal recurring adjustments, including eliminations of material intercompany accounts and transactions) considered necessary for a fair statement of the results presented herein. Operating results for the three and nine months ended September 30, 2024 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2024.

2. Summary of Significant Accounting Policies

During the three and nine months ended September 30, 2024, there were no material changes to our significant accounting policies included in the 2023 Annual Report. For additional information, refer to Note 2 to the audited Consolidated Financial Statements in the 2023 Annual Report.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Impairment of Long-Lived Assets

Long-lived assets, including intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Long-lived assets are grouped with other assets to the lowest level to which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. Management assesses the recoverability of the carrying cost of the assets based on a review of projected undiscounted cash flows. If an asset is held for sale, management reviews its estimated fair value less cost to sell. Fair value is determined using pertinent market information, including appraisals or broker's estimates, and/or projected discounted cash flows. In the event an impairment loss is identified, it is recognized based on the amount by which the carrying value exceeds the estimated fair value of the long-lived asset.

We performed an assessment to determine if there were any indicators of impairment as a result of the operating conditions resulting as of the periods ended September 30, 2024 and December 31, 2023. We concluded that, while there were events and circumstances in the macro-environment that did impact us, we did not experience any entity-specific indicators of asset impairment and no triggering events occurred.

Future Application of Accounting Standards

Segment Reporting

In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07, "Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures" ("ASU 2023-07"), to address improvements to reportable segment disclosures. The standard primarily requires the following disclosure on an annual and interim basis: (i) significant segment expenses that are regularly provided to chief operating decision maker ("CODM") and included within each reported measure of segment profit or loss; and (ii) other segment items and description of its composition. The standard also requires current annual disclosures about a reportable segment's profits or losses and assets to be disclosed in interim periods and the title and position of the CODM with an explanation of how the CODM uses the report measure(s) of segment profits or losses in assessing segment performance. The provisions of the standard are effective for public companies for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The standard is applied retrospectively to all prior periods presented. We are assessing the impact of this standard.

Income Taxes

In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740) - Improvements to Income Tax Disclosures" ("ASU 2023-09"). The standard requires disaggregated information about a company's effective tax rate reconciliation as well as information on income taxes paid. The provisions of the standard are effective for public companies for fiscal years beginning after December 15, 2024, with early adoption permitted. This standard applies prospectively; however, retrospective application is permitted. We are assessing the impact of this standard.

3. Segment Information

The Company has identified two reportable business segments: Electronic Instruments and Merchant Investment. These segments are consistent with the manner in which the chief operating decision maker reviews the business to assess performance and allocate resources. A brief description of each segment is below:

The Electronic Instruments segment includes all products manufactured and sold by PTF.

The Merchant Investment segment includes all activity produced by Lynch Capital International, LLC ("Lynch Capital").

The Company includes in Corporate the following corporate and business activities:

•

corporate level assets and financial obligations such as cash and cash equivalents invested in highly liquid U.S. Treasury money market funds and other marketable securities;

•

other items not allocated to or directly related to the Company's operating segments, including items such as deferred tax balances; and

•

intercompany eliminations.

The Electronic Instruments and Merchant Investment segments are allocated overhead expenses based on each segment's assets as a percentage of total assets.

5. Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value guidance identifies three primary valuation techniques: the market approach, the income approach and the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset.

Fair Value Hierarchy

The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The fair value hierarchy gives the highest priority to observable inputs such as quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The maximization of observable inputs and the minimization of the use of unobservable inputs are required.

Classification within the fair value hierarchy is based upon the objectivity of the inputs that are significant to the valuation of an asset or liability as of the measurement date. The three levels within the fair value hierarchy are characterized as follows:

Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include: quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability; and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3 - Unobservable inputs for the asset or liability for which there is little, if any, market activity for the asset or liability at the measurement date. Unobservable inputs reflect the Company's own assumptions about what market participants would use to price the asset or liability. These inputs may include internally developed pricing models, discounted cash flow methodologies as well as instruments for which the fair value determination requires significant management judgment.

The following is a description of the valuation methodologies used for instruments carried at fair value. These methodologies are applied to asset and liabilities across the levels discussed above, and the observability of the inputs used determines the appropriate level in the fair value hierarchy for the respective asset or liability.

Valuation Methodologies of Financial Instruments Measured at Fair Value

Cash and cash equivalents - Money market instruments are measured at cost, which approximates fair values because of the relatively short time to maturity.

Equity securities - Whenever available, we obtained quoted prices in active markets for identical assets as of the balance sheet date to measure equity securities. Market price data is generally obtained from exchange or dealer markets.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The following table presents information about assets measured at fair value on a recurring basis and indicates the level of the fair value measurement based on the observability of inputs used:

Fair Value Measurements on a Non-Recurring Basis

The Company has other assets that may be subject to measurement at fair value on a non-recurring basis including goodwill and intangible assets and other long-lived assets. The Company reviews goodwill annually and the carrying value of long-lived assets whenever events and circumstances indicate that the carrying amounts of the assets may not be recoverable. If it is determined that the assets are impaired, the carrying value would be reduced to an estimated recoverable value. The Company's common stock warrants (as defined below) were measured at fair value as disclosed in Note 11 - Stockholders' Equity to the Consolidated Financial Statements in the 2023 Annual Report.

As of September 30, 2024 and December 31, 2023, the Company did not write down any assets to fair value.

Fair Value Information about Financial Instruments Not Measured at Fair Value

As of September 30, 2024 and December 31, 2023, the Company did have any assets or liabilities classified as financial instruments that were not measured at fair value.

6. Variable Interest Entities

The Company holds variable interests in certain entities in the form of equity investments. The Company consolidates an entity under the variable interest entity ("VIE") guidance when it is determined the Company is the primary beneficiary.

The Company has no right to the benefits from, nor does it bear the risk associated with, VIEs beyond the Company's direct equity investments in these entities. If the Company were to liquidate, the assets held by VIEs would not be available to the general creditors of the Company as a result of the liquidation.

During June 2023, the Company was appointed as sole managing member of LGL Systems Nevada Management Partners, LLC ("LGL Nevada") and invested approximately $4 into LGL Nevada, representing the Company's 1.0% general partnership interest. Concurrently, Lynch Capital, a wholly owned subsidiary of the Company, invested $1,000 into LGL Systems Acquisition Holding Company, LLC ("LGL Systems"), representing 34.8% of the memberships in LGL Systems, which is controlled by LGL Nevada. As a result, the Company determined it was the primary beneficiary of LGL Systems and was therefore required to consolidate LGL Systems.

Consolidated VIEs

The Company's only consolidated VIE is LGL Systems.

The following table summarizes the assets and liabilities of LGL Systems included in the Condensed Consolidated Balance Sheets:

	September 30, 2024		December 31, 2023

Investment Activity with GAMCO Investors, Inc.

Certain balances held and invested in various mutual funds are managed or advised by GAMCO Investors, Inc. or one of its subsidiaries (collectively, "GAMCO" or the "Fund Manager"), which is related to the Company through certain of our shareholders. All investments, including those in related party mutual funds, are overseen by the independent Investment Committee of the Board of Directors (the "Investment Committee"). The Investment Committee meets regularly to review the alternatives and has determined the current investments most reflect the Company's objective of lower cost, market return and adherence to having a larger proportion of underlying investments directly in United States Treasuries.

As of September 30, 2024, the balance managed by the Fund Manager totaled $33,931, all of which was classified within Cash and cash equivalents on the Condensed Consolidated Balance Sheets. As of December 31, 2023, the balance managed by the Fund Manager totaled $32,568, all of which was classified within Cash and cash equivalents on the Condensed Consolidated Balance Sheets.

For the three months ended September 30, 2024, the Company earned income on its investments managed by the Fund Manager totaling $444, all of which was included in Net investment income on the Condensed Consolidated Statements of Operations.

Transactions with M-tron Industries, Inc.

Transitional Administrative and Management Services Agreement

On October 7, 2022, the separation of the M-tron Industries, Inc. ("MtronPTI") business from the Company was completed (the "Separation") and the business became an independent, publicly traded company trading on the NYSE American under the stock symbol "MPTI." The Separation was completed through the Company's distribution (the "Distribution") of 100% of the shares of MtronPTI's common stock to holders of the Company's common stock as of the close of business on September 30, 2022, the record date for the Distribution.

LGL Group and MtronPTI entered into an Amended and Restated Transitional Administrative and Management Services Agreement ("MtronPTI TSA"), which sets out the terms for services to be provided between the two companies post-separation. The current terms result in a net monthly payment of $4 per month to MtronPTI.

For the three months ended September 30, 2024 and 2023, the Company paid MtronPTI $12 under the terms of the MtronPTI TSA, which were recorded in Engineering, selling and administrative on the Condensed Consolidated Statements of Operations. For the nine months ended September 30, 2024 and 2023, the Company paid MtronPTI $36, respectively, under the terms of the MtronPTI TSA, which were recorded in Engineering, selling and administrative on the Condensed Consolidated Statements of Operations.

Tax Indemnity and Sharing Agreement

LGL Group and MtronPTI entered into a Tax Indemnity and Sharing Agreement ("MtronPTI Tax Agreement"), which sets out the terms for which party would be responsible for taxes imposed on the Company if the distribution, together with certain related transactions, were to fail to qualify as a tax-free transaction under Internal Revenue Code ("IRC") Sections 355 and 368(a)(1)(D) if such failure were the result of actions taken after the Distribution by the Company or MtronPTI.

For the three and nine months ended September 30, 2024 and 2023, no taxes related to the Distribution have been recorded in the Condensed Consolidated Financial Statements.

Other Transactions

LGL Group and MtronPTI have agreed to share salaries and benefits related to certain employees incurred by the Company. For the three and nine months ended September 30, 2024, MtronPTI reimbursed the Company $27 and $80, respectively, of the salaries and benefits of certain employees, which represents 50% of those costs and were recorded as a reduction to Engineering, selling and administrative on the Condensed Consolidated Statements of Operations.

LGL Group and MtronPTI agreed to share any excess Separation costs. Included in discontinued operations is $28, which represents 50% of the excess Separation costs incurred for nine months ended September 30, 2023.

8. Income Taxes

The Company’s quarterly provision for income taxes is measured using an annual effective tax rate, adjusted for discrete items within the period presented. To determine the annual effective tax rate, the Company estimates both the total income (loss) before income taxes for the full year and the jurisdictions in which that income (loss) is subject to tax. The actual effective tax rate for the full year may differ from these estimates if income (loss) before income taxes is greater than or less than what was estimated or if the allocation of income (loss) to jurisdictions in which it is taxed is different from the estimated allocations.

The Company's effective tax rates on continuing operations for the three and nine months ended September 30, 2024 were 34.8% and 35.2%, respectively. The Company's effective tax rates on continuing operations for the three and nine months ended September 30, 2023 were 34.7% and 41.6%, respectively. The effective tax rates differed from the statutory tax rate of 21% primarily due to the impact of uncertain tax positions and state income taxes.

9. Stock-Based Compensation

Under the Company’s 2021 Incentive Plan (the "Plan"), and the prior 2011 Incentive Plan, as amended, stock-based compensation may be issued to employees and non-employee directors. As of September 30, 2024, 955,070 shares remained available for future issuance under the Plan.

The following table summarizes stock-based compensation expense, which includes expenses related to awards granted under the Plan for the periods indicated:

^(b)	Basic and diluted earnings per share are calculated using actual, unrounded amounts. Therefore, the components of earnings per share may not sum to its corresponding total.

The LGL investment business is comprised of various investment vehicles in which LGL is either shareholder, partner, or has general partner interests, and through which LGL invests its capital. The Company seeks to invest available cash and cash equivalents in liquid investments with a view to enhancing returns as we continue to assess further acquisitions of, or investments in, operating businesses broadly. LGL core strengths include identifying and acquiring undervalued assets and businesses, often through the purchase of securities, increasing value through management, financial or other operational changes, and managing complex legal, regulatory or financial issues, which may include technical, engineering, environmental, zoning, permitting and licensing issues among others.

Market Conditions and Search Process

During the nine months ended September 30, 2024, mergers and acquisitions continued to be impacted by macroeconomic conditions such as higher borrowing costs, increased regulatory scrutiny, political uncertainty, and higher valuation expectations. The initial public offering ("IPO") market has been relatively weak with continued pressure on private equity sponsors to monetize their portfolio companies, which has improved the pace and quality of deal flow to our team.

Our search process leverages our professional networks and relationships, participation in industry events and conferences, monitoring of industry trends and news, and interactions with our shareholders, investment banks, and other intermediaries. We continue to seek small- to mid-sized opportunities with strong cash flow generating capacity that trade at reasonable multiples with competitive products or services and with defensible market positions or intellectual property.

Trends and Uncertainties

We are not aware of any material trends or uncertainties, other than global macroeconomic conditions affecting our industry generally that may reasonably be expected to have a material impact, favorable or unfavorable, on our revenues or income other than those listed below and those listed in Item 1A, Risk Factors, of our Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the SEC on April 1, 2024.

Changing Interest Rates

The U.S. Federal Reserve raised the federal funds rate a total of four times throughout 2023, resulting in a range from 5.25% to 5.50% as of December 31, 2023. Through the date of filing of this Quarterly Report on Form 10-Q, the U.S. Federal Reserve decreased the federal funds rate twice totaling 75 basis points to a range of 4.50% to 4.75%. It is expected that the U.S. Federal Reserve will continue to decrease the federal funds rate during 2024 and 2025 to, among other things, control inflation; however, the timing of any future decreases remains unclear. If interest rates continue to decline, the returns generated by our investments in U.S. Treasuries could be adversely impacted.

Liquidity and Capital Resources

Overview

Liquidity refers to our ability to access sufficient sources of cash to meet the requirements of our operating, investing and financing activities.

Capital refers to our long-term financial resources available to support business operations and future growth.

Our ability to generate and maintain sufficient liquidity and capital depends on the profitability of the businesses, timing of cash flows, general economic conditions and access to the capital markets and the other sources of liquidity and capital described herein.

As of September 30, 2024 and December 31, 2023, Cash and cash equivalents were $41,602 and $40,711, respectively.

Capital Resources

We believe that existing cash and cash equivalents, marketable securities and cash generated from operations will provide sufficient liquidity to meet our ongoing working capital and capital expenditure requirements for the next 12 months from the date of this filing and for the foreseeable future.

Our Board has adhered to a practice of not paying cash dividends. This policy takes into account our long-term growth objectives, including our anticipated investments for organic growth, potential acquisitions and stockholders' desire for capital appreciation of their holdings. No cash dividends have been paid to the Company's stockholders since January 30, 1989, and none are expected to be paid for the foreseeable future.

Contractual Obligations

As of September 30, 2024, there have been no material changes in our contractual obligations from December 31, 2023, a description of which may be found in Part II, Item 7. Management Discussion and Analysis - Liquidity and Capital Resources - Contractual Obligations in the 2023 Annual Report.

Critical Accounting Estimates

Our accompanying Condensed Consolidated Financial Statements are prepared in conformity with U.S. GAAP, which requires management to make estimates and assumptions that affect the amounts reported in our financial statements and accompanying footnotes. These estimates are made and evaluated on an on-going basis using information that is currently available as well as various other assumptions believed to be reasonable under the circumstances. Actual results could differ from those estimates, perhaps in material adverse ways, and those estimates could be different under different assumptions or conditions. For a discussion of the Company’s critical accounting estimates, see Item 7.

Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports under the Securities Exchange Act of 1934, as amended (the "Exchange Act") is recorded, processed, summarized and reported within the time periods specified in the rules and forms, and that such information is accumulated and communicated to us, including our Principal Executive Officer and Principal Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

As required by Rules 13a-15(b) and 15d-15(b) of the Exchange Act, an evaluation as of September 30, 2024 was conducted under the supervision and with the participation of our management, including our Principal Executive Officer and Principal Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on this evaluation, our Principal Executive Officer and Principal Financial Officer concluded that our disclosure controls and procedures, as of September 30, 2024, were effective.

Changes in Internal Control Over Financial Reporting

There were no changes in the Company’s internal control over financial reporting during the quarter ended September 30, 2024 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Significant Accounting Policies (Policies)	9 Months Ended
Significant Accounting Policies (Policies)	Sep. 30, 2024
Accounting Policies [Abstract]
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	*Impairment of Long-Lived Assets* Long-lived assets, including intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Long-lived assets are grouped with other assets to the lowest level to which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. Management assesses the recoverability of the carrying cost of the assets based on a review of projected undiscounted cash flows. If an asset is held for sale, management reviews its estimated fair value less cost to sell. Fair value is determined using pertinent market information, including appraisals or broker's estimates, and/or projected discounted cash flows. In the event an impairment loss is identified, it is recognized based on the amount by which the carrying value exceeds the estimated fair value of the long-lived asset. We performed an assessment to determine if there were any indicators of impairment as a result of the operating conditions resulting as of the periods ended September 30, 2024 and December 31, 2023. We concluded that, while there were events and circumstances in the macro-environment that did impact us, we did not experience any entity-specific indicators of asset impairment and no triggering events occurred.
New Accounting Pronouncements, Policy [Policy Text Block]	Future Application of Accounting Standards Segment Reporting In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07, "Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures" ("ASU 2023-07"), to address improvements to reportable segment disclosures. The standard primarily requires the following disclosure on an annual and interim basis: (i) significant segment expenses that are regularly provided to chief operating decision maker ("CODM") and included within each reported measure of segment profit or loss; and (ii) other segment items and description of its composition. The standard also requires current annual disclosures about a reportable segment's profits or losses and assets to be disclosed in interim periods and the title and position of the CODM with an explanation of how the CODM uses the report measure(s) of segment profits or losses in assessing segment performance. The provisions of the standard are effective for public companies for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The standard is applied retrospectively to all prior periods presented. We are assessing the impact of this standard. Income Taxes In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740) - Improvements to Income Tax Disclosures" ("ASU 2023-09"). The standard requires disaggregated information about a company's effective tax rate reconciliation as well as information on income taxes paid. The provisions of the standard are effective for public companies for fiscal years beginning after December 15, 2024, with early adoption permitted. This standard applies prospectively; however, retrospective application is permitted. We are assessing the impact of this standard.
