Current report
Total revenue increased $23.7 million, or 13% for the three months ended June 30, 2026, compared to the three months ended June 30, 2025, driven by increases in both product and service revenue. Product revenue increased 18%, driven by increased enterprise demand for service assurance offerings, which included revenue related to U.S. Government agencies. Service revenue increased 9%, primarily due to the timing and composition of maintenance and contract renewals and to a lesser extent incremental revenue from the DigiCert DDoS protection business acquisition on May 1, 2026. U.S. revenue increased 24%, benefiting from increased enterprise and service provider demand while international revenue decreased 1%. By product line, service assurance revenue increased 20% due to an increase in revenue from enterprise and service provider customers that included the benefit in part from government-related orders, some of which were received earlier than anticipated. Cybersecurity revenue increased 1% due to incremental revenue from the DigiCert DDoS protection business acquisition partially offset by a decrease in product revenue from enterprise customers. From a customer-vertical perspective, enterprise revenue increased 19%, driven by an increase in both product and service revenue and service provider revenue increased 3%.
Current report
The 8%, or $2.1 million, decrease in general and administrative expenses for the three months ended June 30, 2026 compared to the same period last year was primarily due to a $1.1 million decrease in stock based compensation driven by the retirement of our former Chief Financial Officer and Chief Operating Officer, a $1.0 million decrease associated with the elimination of the costs associated with the previous one-year senior advisor roles of our former Chief Financial Officer and Chief Operating Officer, a $0.5 million decrease in professional service costs, a $0.5 million decrease in legal expenses, and a $0.4 million increase in software capitalization, partially offset by an increase in employee-related variable incentive compensation.

Total revenue increased $38.8 million, or 6%, for the nine months ended December 31, 2025, as compared to total revenue for the nine months ended December 31, 2024.

We continue to closely monitor current global and macroeconomic conditions, including the impacts of the ongoing war in Ukraine and hostilities in the Middle East, global geopolitical tension, stock market volatility, industry-specific capital spending trends, exchange rate fluctuations, inflation, interest rates, international trade relations (including trade protection measures, such as tariffs and other trade barriers), and the risk of a recession, including the manner and extent to which they have impacted and could continue to impact our business, customers, employees, supply chain, and distribution network. In addition, our industry is experiencing AI-related supply-chain dynamics which could influence the timing and size of certain customer orders. The full extent of the impacts of these global and macroeconomic conditions remain dynamic. In response to the war in Ukraine, we ceased business operations in Russia, including sales, support on existing contracts and professional services. We remain optimistic but cognizant of ongoing macroeconomic dynamics and constrained customer spending in the service provider market and firmly focused on driving product innovation, returning to annual revenue growth, and enhancing margins through continued disciplined cost management as we navigate the current macroeconomic landscape that may persist through fiscal year 2026. As a result, we have continued our efforts to manage discretionary costs and align spending with the current environment while we continue to execute on our long-term strategic plans.

This represents an increase of $93.7 million from $492.5 million at March 31, 2025. This increase was primarily due to $142.3 million of net cash provided by operations, $11.8 million in proceeds from the sale of our entire Napatech equity investment and a $47.1 million in proceeds from the maturity of marketable securities. Partially offsetting the increase was $69.3 million in purchases of marketable securities, $31.6 million used to repurchase shares of our common stock, $15.7 million used for tax withholdings on restricted stock units and $6.9 million used for capital expenditures during the nine months ended December 31, 2025.

We supplement the United States GAAP financial measures we report in quarterly and annual earnings announcements, investor presentations and other investor communications by reporting the following non-GAAP measures: non-GAAP gross profit, non-GAAP income from operations, non-GAAP operating margin, non-GAAP net income, non-GAAP diluted net income per share, and adjusted EBITDA. Non-GAAP gross profit removes expenses related to the amortization of acquired intangible assets, share-based compensation expense, and acquisition-related depreciation expense. Non-GAAP income from operations includes the aforementioned adjustments related to non-GAAP gross profit and also removes goodwill impairment charges, executive transition costs, and restructuring charges. Non-GAAP operating margin is non-GAAP income from operations expressed as a percentage of revenue. Non-GAAP net income includes the foregoing adjustments related to non-GAAP income from operations, and also removes the income tax effects of such adjustments as well as any loss on extinguishment of debt. Non-GAAP diluted net income per share is non-GAAP net income divided by total outstanding shares on a diluted basis. Adjusted EBITDA (formerly non-GAAP EBITDA from operations) includes the aforementioned adjustments related to non-GAAP net income and also removes interest and other expense, income taxes, and non-acquisition related depreciation from net income (GAAP). Beginning this quarter, we have renamed non-GAAP EBITDA from operations to adjusted EBITDA. We now reconcile this metric to GAAP net income, however, the adjustments included, and the resulting amounts are unchanged from prior periods. This change is intended to align terminology with common market practice.

Adjusted EBITDA includes the aforementioned adjustments related to non-GAAP net income and also removes interest and other expense, income tax expense, and non-acquisition related depreciation from net income (GAAP). Beginning in the third quarter of fiscal year 2026, we have renamed non-GAAP EBITDA from operations to adjusted EBITDA. We now reconcile this metric to GAAP net income; however, the adjustments included, and the resulting amounts are unchanged from prior periods. This change is intended to align terminology with common market practice.

These non-GAAP measures are not prepared in accordance with GAAP, should not be considered an alternative for measures prepared in accordance with GAAP (gross profit, operating margin, net income, and diluted net income per share), and may have limitations because they do not reflect all our results of operations as determined in accordance with GAAP. These non-GAAP measures should only be used to evaluate our results of operations in conjunction with the corresponding GAAP measures. The presentation of non-GAAP information is not meant to be considered superior to, in isolation from, or as a substitute for results prepared in accordance with GAAP. These non-GAAP measures should not be used to evaluate our results of operations against those of our peers or other companies, as the definitions and calculations of our non-GAAP measures may not be the same as those used by other companies, even if the measures share the same name.

We produce our products on the basis of our forecast of near-term demand and maintain inventory in advance of receipt of firm orders from customers. We configure our products to customer specifications and generally deliver products shortly after receipt of the purchase order. Service engagements are also included in certain orders. Customers generally may reschedule or cancel unfulfilled orders with little or no penalty. Our total backlog at any particular time is not necessarily indicative of future sales levels. Within total backlog, fulfillable backlog includes what we consider to represent orders that are generally available to be delivered to customers as of the end of the reporting period. Delivery of our fulfillable backlog typically occurs early in the subsequent quarter. However, delivery may be delayed or accelerated due to various other reasons, including but not limited to, changes in timing of customer projects and product delivery schedules, which may not be within our control. Our total combined product backlog at December 31, 2025 was $24.0 million compared to $33.1 million at March 31, 2025. Combined product backlog included fulfillable backlog of $18.7 million and $25.1 million at December 31, 2025 and March 31, 2025, respectively.

We have contractual obligations for operating leases, unconditional purchase obligations, pension benefits plans and certain other long-term liabilities. Our obligations related to these items are described further within Management’s Discussion and Analysis of Financial Condition and Results of Operations within our Annual Report. We expect net cash provided by operating activities combined with cash, cash equivalents, marketable securities and investments and borrowing availability under our revolving credit facility will provide sufficient liquidity to fund current obligations, capital spending, debt service requirements and working capital requirements over at least the next twelve months. We believe we will meet longer-term expected future cash requirements and obligations through a combination of cash flows from operating activities, available cash balances, and our revolving credit facility. However, macroeconomic conditions, including high inflation and interest rates, international trade relations (including trade protections measures, such as tariffs and other trade barriers), and a potential recession, could increase our anticipated funding requirements or make it more difficult for us to access capital.

A portion of our cash may be used to acquire or invest in complementary businesses or products, to obtain the right to use complementary technologies, or to repurchase shares of our common stock through our stock repurchase programs. From time to time, in the ordinary course of business, we evaluate potential acquisitions of such businesses, products or technologies. If our existing sources of liquidity are insufficient to satisfy our liquidity requirements, we may seek to sell additional equity or debt securities. Macroeconomic conditions, including high interest rates and volatility in the capital markets, may make it difficult for us to secure additional financing on favorable terms or at all. Any sale of additional equity or debt securities could result in additional dilution to our stockholders.
