TEL AVIV, Israel, May 7, 2026 - Radware® (NASDAQ: RDWR), a global leader in application security and delivery solutions for multi-cloud environments, today announced its consolidated financial results for the first quarter ended March 31, 2026.

“We delivered a strong start to 2026, marked by solid execution across the business and sustained double‑digit revenue growth,” said Roy Zisapel, president and CEO of Radware. “Growth in the quarter was led by our cloud security business supported by strong momentum in our new API Protection, while our on‑prem DDoS protection portfolio, led by DefensePro X, performed exceptionally well. We also saw outstanding execution in North America, reflecting the strength of our go‑to‑market strategy. These results demonstrate the progress we are making in executing our strategy as we scale our platform and capitalize on the growing opportunities in cloud and API security.”

Financial Highlights for the First Quarter 2026

Revenue for the first quarter of 2026 totaled $79.8 million:

•

Revenue in the Americas region was $38.4 million for the first quarter of 2026, an increase of 40% from $27.4 million in the first quarter of 2025.

•

Revenue in the Europe, Middle East, and Africa (“EMEA”) region was $25.1 million for the first quarter of 2026, a decrease of 11% from $28.3 million in the first quarter of 2025.

•

Revenue in the Asia-Pacific (“APAC”) region was $16.3 million for the first quarter of 2026, the same as in the first quarter of 2025.

GAAP net income from continuing operations for the first quarter of 2026 was $6.1 million, or $0.14 per diluted share, compared to GAAP net income from continuing operations of $6.6 million, or $0.15 per diluted share, for the first quarter of 2025.

Non-GAAP net income from continuing operations for the first quarter of 2026 was $13.4 million, or $0.30 per diluted share, compared to non-GAAP net income from continuing operations of $13.6 million, or $0.31 per diluted share, for the first quarter of 2025.

The appreciation of the Israeli shekel against the U.S. dollar had an adverse impact on expenses during the first quarter. Excluding the effect of foreign exchange movements compared to last year, non-GAAP net income and non-GAAP diluted EPS would have been $15.6 million and $0.35 respectively, compared to non-GAAP net income of $13.6 million, or $0.31 per diluted share, for the first quarter of 2025.

As of March 31, 2026, the Company had cash, cash equivalents, short-term and long-term bank deposits, and marketable securities of $433.8 million. Cash flow provided by continuing operations was $19.9 million in the first quarter of 2026.

Non-GAAP results are calculated excluding, as applicable, the impact of stock-based compensation expenses, amortization of intangible assets, litigation costs, acquisition costs, restructuring costs, exchange rate differences, net on balance sheet items included in financial income, net, and tax-related adjustments. A reconciliation of each of the Company’s non-GAAP measures to the most directly comparable GAAP measure is included at the end of this press release.

As announced last quarter, the results of our subsidiary, SkyHawk, have been classified as discontinued operations effective the first quarter of 2026 and are presented accordingly. As a result, all financial results discussed today relate solely to continuing operations. In connection with this change, the previously reported Hawks segment will no longer be presented separately. Comparative prior‑year figures have been adjusted to align with this presentation and ensure consistency.

Use of Non-GAAP Financial Information and Key Performance Indicators

In addition to reporting financial results in accordance with generally accepted accounting principles (GAAP), Radware uses non-GAAP measures of gross profit, research and development expense, selling and marketing expense, general and administrative expense, total operating expenses, operating income, financial income, net, income before taxes on income, taxes on income, net income and diluted earnings per share, which are adjustments from results based on GAAP to exclude, as applicable, stock-based compensation expenses, amortization of intangible assets, litigation costs, acquisition costs, restructuring costs, exchange rate differences, net on balance sheet items included in financial income, net, and tax-related adjustments. Management believes that exclusion of these charges allows for meaningful comparisons of operating results across past, present, and future periods. Radware’s management believes the non-GAAP financial measures provided in this release are useful to investors for the purpose of understanding and assessing Radware’s ongoing operations. The presentation of these non-GAAP financial measures is not intended to be considered in isolation or as a substitute for results prepared in accordance with GAAP. A reconciliation of each non-GAAP financial measure to the most directly comparable GAAP financial measure is included with the financial information contained in this press release. Management uses both GAAP and non-GAAP financial measures in evaluating and operating the business and, as such, has determined that it is important to provide this information to investors.

Annual recurring revenue ("ARR") is a key performance indicator defined as the annualized value of booked orders for term-based cloud services, subscription licenses, and maintenance contracts that are in effect at the end of a reporting period. ARR should be viewed independently of revenue and deferred revenue and is not intended to be combined with or to replace either of those items. ARR is not a forecast of future revenue, which can be impacted by contract start and end dates and renewal rates and does not include revenue reported as perpetual license or professional services revenue in our consolidated statement of operations. We consider ARR a key performance indicator of the value of the recurring components of our business.
