Update to Purchase of 1 Million Newly Issued Shares of Morgan Group Holding Co. (OTC Pink: MGHL)

The purchase remains pending final multi-party agreements, certain approvals and final diligence. We continue to believe this transaction will be completed in 2025. LGL Group entered into an amended and restated subscription agreement to purchase, via a private placement, 1,000,000 newly issued shares of Morgan Group Holding Co. ("MGHL") common stock for $2.00 per share in April 2025. This transaction has received approval from MGHL’s directors, and shareholders and once completed MGHL will have approximately 1.6 million shares outstanding and is expected to close in the third quarter.

MGHL, through its wholly owned subsidiary, G.research, LLC ("G.R"), provides brokerage, underwriting, and institutional research services. G.R is a broker-dealer registered under the Securities Exchange Act of 1934, as amended, and is a member of the Financial Industry Regulatory Authority ("FINRA"). G.R has over $5.0 billion of private client assets held in over 1,000 accounts. G.R also sponsors a series of industry-focused investment conferences featuring leading public and private companies in sectors with a high degree of investor interest. The conferences cover important sectors, including automotive and aerospace and defense. MGHL will continue to trade as an independently listed company with its own set of shareholders.

Once closed, Herve Francois will join MGHL as Chairman and Chief Executive Officer and Chris Nossokoff will join as Chief Financial Officer. G.R. will continue to be led by Vincent Amabile as President and Joseph Fernandez as Financial Operations Principal and Controller and continue to manage and build the strength of the platform.

New Initiatives Continue

Further expanding adjacent capabilities with the Company’s PTF division, P3 Logistic Solutions LLC ("P3") is developing new opportunities with AI-driven tactical edge device prototypes. P3 is preparing to field test on farms, adapting technology originally engineered for U.S. Department of Defense use cases to meet the challenges of modern agriculture. These ruggedized edge systems deliver real-time, autonomous decision-making without relying on centralized networks — ensuring uninterrupted operation in remote and demanding conditions.

The trials will apply the technology to precision crop monitoring, smart irrigation control, and autonomous asset tracking, bringing smart analytics and resilience to the field. Testing will measure gains in efficiency, resource optimization, and operational performance across diverse farming environments, laying the foundation for scalable deployment.

We do not expect to recognize any material benefits from our new initiatives in 2025 but expect to develop value in the medium term.

Gross Margin

Gross margin decreased to 57.0% for the three months ended June 30, 2025 compared to 59.7% for the three months ended June 30, 2024. The decrease was primarily due to sales of lower margin products.

The decrease was primarily due to lower Net investment income on investments in U.S. Treasury money market funds due to lower yields partially offset by higher Net sales driven by higher product shipments.
