RADCOM Announces Preliminary Second Quarter
Revenue and Updated Full-Year Guidance
Customer Deployment Delays Driven by Higher
Component Costs and Supply Constraints Impact Second Quarter Revenue and Full-Year Outlook
Second Quarter Earnings Release Call to be held
on August 12
TEL AVIV, Israel – July 30, 2026 − RADCOM Ltd. (Nasdaq:
RDCM) (the “Company”) today announced preliminary second quarter revenue expectations and updated its full-year 2026 outlook
ahead of its August 12, 2026 earnings release.
Based on preliminary analysis, management currently expects second
quarter revenue to be approximately $12 million. This reflects customer deployment delays that have delayed customer purchasing decisions.
The Company did not experience cancellations or competitive losses and believes these dynamics reflect timing considerations rather than
changes in demand.
“These delays are impacting the purchasing decisions of several
of our customers, affecting our second quarter revenue and full year guidance,” commented RADCOM’s Chief Executive Officer, Benny
Eppstein. “These delays became evident during the last few weeks of the quarter, and, based on what we know today, they could continue
to affect the timing of revenue through the balance of 2026.”
As a result, management is reducing its full-year 2026 revenue outlook
to a range of $57 - $63 million, with a midpoint of $60 million.
Management expects RADCOM to remain profitable on a non-GAAP basis
for full-year 2026, inclusive of these revenue headwinds.
“Demand for our solutions and our relationships with existing
customers remain strong,” Mr. Eppstein added. “Our focus is on executing against the opportunities in front of us, supporting
our existing customers and positioning the Company to return to sustainable growth as customer deployment activity normalizes. We expect
to return to double-digit growth in 2027.”

of the Private Securities Litigation Reform Act of 1995 and other securities laws. For example, when the Company discusses its preliminary
second quarter 2026 revenue expectations, its updated full-year 2026 revenue outlook and guidance, its expectation of continued Non GAAP
profitability for full-year 2026, the expected timing, duration and impact of the customer deployment delays on the timing of revenue
through the balance of 2026, its belief that these dynamics reflect timing considerations rather than changes in demand, its expectation
of returning to sustainable growth as customer deployment activity normalizes, and its expectation of returning to double-digit growth
in 2027, it is using forward-looking statements. These forward-looking statements involve known and unknown risks and uncertainties that
could cause the actual results, performance, or achievements of the Company to be materially different from those that may be expressed
or implied by such statements, including, among others, changes in general economic and business conditions and, specifically, a decline
in demand for the Company’s products, delays in customer deployments and purchasing decisions, the risk that the Company’s preliminary
results differ from its final reported results for the second quarter of 2026, the Company’s ability to achieve its full-year 2026
revenue guidance and to return to growth, the inability to timely develop and introduce new technologies, products, and applications,
the timing of customer collections and resulting fluctuations in operating cash flow, reliance on a concentrated customer base, loss of
market share and pressure on prices resulting from competition, and the effects of the conflict in Israel. For additional information
regarding these and other risks and uncertainties associated with the Company’s business, reference is made to the Company’s reports filed
