TEL AVIV, Israel – May 19, 2026 – RADCOM Ltd. (Nasdaq: RDCM), a leading provider of advanced, intelligent assurance solutions with integrated AI Operations (AIOps) capabilities, announced today its financial results for the first quarter ended March 31, 2026.

“We delivered another quarter of sustained, profitable growth, with first-quarter revenue of $18.6 million, up 12% year-over-year,” said Benny Eppstein, RADCOM’s Chief Executive Officer. “Our focused execution continues to translate top-line growth into expanding margins, reinforced by a multi-year renewal with a Tier-1 operator that expands its RADCOM ACE footprint to power more AI-driven, automated network operations.”

“Looking ahead, we’re encouraged by customers’ reception of RADCOM Neura, our AI agent suite designed for integration into agentic AI ecosystems,” Eppstein continued. “We remain focused on disciplined execution, deepening installed-base relationships, winning new customers, and advancing our AI-native, event-driven assurance capabilities as networks move toward greater automation.”

RADCOM is reaffirming its full-year 2026 revenue guidance of 8% to 12% year-over-year growth, implying $78.6 million at the midpoint (10%).

Board of Directors Update

Rami Schwartz, Rachel (Heli) Bennun, Yaron Ravkaie, and Oren Most stepped down from the Board of Directors, effective May 19, 2026, and Andre Fuetsch stepped down from the Board of Directors, effective May 18, 2026. Shareholders will vote on the election of new directors at an extraordinary general meeting on May 20, 2026, as detailed in the proxy materials filed on April 15, 2026, with the Securities and Exchange Commission.

“On behalf of the Company, I want to thank Rami, Heli, Andre, Yaron, and Oren for their significant contributions. With their help and guidance, the Company achieved four consecutive years of double-digit revenue growth, transforming from an unprofitable company to a profitable one and increasing the Company’s net cash position by over $15 million in 2025, and then reaching $108.4 million of cash, cash equivalents, and short-term bank deposits at the end of March 2026, with no debt,” said RADCOM’s Chief Executive Officer, Benny Eppstein.

Rami Schwartz, the outgoing Chairman, said, “It has been a privilege to serve as Chairman of RADCOM and to work alongside a very talented, supportive, and dedicated Board for many years. The Company is in a strong position, with a track record of six consecutive years of revenue growth and four years of improved profitability, a capable management team, and committed employees. We decided to resign from the Board of Directors and not to conduct a proxy contest, as we preferred to focus on RADCOM’s best interests and minimize potentially harmful effects of a prolonged process.”

Mr. Schwartz added, “Moreover, the Company is now equipped with best-in-class AI-based solutions for 4G and 5G networks and is trusted and adopted by highly satisfied Tier-1 service providers, which continue to adopt more RADCOM solutions. Special thanks to Heli Bennun, who served as our Executive Chairman for almost a decade, spanning most of this successful period. She tirelessly pushed for the technical and business achievements we are so proud of. I thank RADCOM’s CEO Benny Eppstein, COO Hilik Itman, the Company’s executive team, and my fellow directors for their partnership and active pursuit of RADCOM’s growth and success. We look forward to RADCOM’s next successful chapter.”
