Exhibit 99.1

THE LGL GROUP, INC. ANNOUNCES STRATEGIC INVESTMENT IN SKYLINE INSTRUMENTS CORPORATION

ORLANDO, Florida (June 17, 2026) The LGL Group, Inc. (NYSE American: LGL) ("LGL Group" or the "Company") today announced a strategic investment into Skyline Instruments Corporation ("Skyline"), a dual-use commercial and defense technology company developing precision timing and synchronized sensing infrastructure for environments where GPS is fragile, contested, or unavailable.

"As the defense landscape continues to evolve, our ability to identify and support emerging technology companies is a critical part of how we deliver long-term value to our shareholders. This investment reflects our confidence in Skyline’s team and their technology, and we look forward to supporting their growth as a strategic capital partner," said Jason Lamb, LGL Group Chief Executive Officer. "Our merchant investing strategy allows LGL Group to deploy capital alongside exceptional management teams and technologies that align with our long-term vision. We view these investments as more than financial opportunities – they expand our industry network, enhance strategic insight, and create potential pathways for future partnerships, acquisitions, and value creation across our platform."

"Securing this investment from LGL Group is a meaningful milestone for our company. This capital gives us the runway to accelerate our growth, expand our team, and continue building technology for our customers. Having a publicly traded partner behind us speaks to the strength and import of what we are building," said Kyle McKuhen, Skyline Chief Executive Officer.
