Consolidated Results

Second Quarter 2026 

Total revenues were $1,153,000 for the three months ended June 30, 2026 compared to $924,000 for the three months ended June 30, 2025. The increase was primarily due to the $259,000 increase in Net sales within our Electronic Instruments segment due to higher product shipments as orders in backlog as of March 31, 2026 converted to revenue partially offset by the $16,000 decrease in Net investment income driven by lower yields on investments in United States Treasury money market funds and the $14,000 decrease in Net gains (losses) driven by lower mark-to-market movements on Marketable securities.

Gross margin was 49.2% for the three months ended June 30, 2026 compared to 57.0% for the three months ended June 30, 2025. The decrease was primarily due to changes in product and pricing mix associated with volume-based pricing extended to a single customer in connection with increased order volume partially offset by the increase in Net sales discussed above.

Net loss attributable to LGL Group common stockholders was ($353,000), or ($0.06) per diluted share, compared with ($51,000), or ($0.01) per diluted share, in the second quarter of 2025. The decrease was primarily due to higher Engineering, selling, and administrative expenses driven by a $143,000 increase in stock-based compensation, a $100,000 increase in professional service fees, a $37,000 increase in salaries and wages and related benefits, and a $78,000 increase in other corporate expenses partially offset by higher Net sales discussed above.

Gross margin was 50.1% for the six months ended June 30, 2026 compared to 54.7% for the six months ended June 30, 2025.

The increase was primarily due to higher Engineering, selling, and administrative expenses driven by $822,000 higher stock-based compensation related to grants made to key employees in January and May 2026, a $300,000 increase in professional service fees, a $85,000 increase in salaries and wages and related benefits, and a $100,000 increase in other corporate expenses partially offset by higher Net sales due to higher product shipments as orders in backlog converted to revenue.

Cash and cash equivalents and marketable securities were $45.2 million as of June 30, 2026 compared to $41.6 million as of December 31, 2025. The increase was primarily due to $4.6 million of net proceeds from the warrant dividend program completed in January 2026 and $1.2 million in capital contributions from non-controlling interests into Skyline Instruments May 2026, a Series of CGF2021 LLC partially offset by the $2.0 million investment in the convertible promissory note issued by Skyline Instruments Corporation.

Book value attributable to LGL Group common stockholders was $6.77 as of June 30, 2026 compared to $7.04 as of December 31, 2025. The decrease was primarily due to the net loss attributable to LGL Group common stockholders discussed above, the increase in shares outstanding resulting from restricted stock grants to key employees in January and May 2026 for which a portion vested immediately, and the increase in shares outstanding related to the warrant program completed in January 2026, pursuant to which shares were issued at an exercise price of $4.75 per share.
