Qualys Announces Second Quarter 2026 Financial Results
Q2 Revenue Growth of 11% Year-Over-Year
Raises 2026 Revenue Guidance to $732.0-$738.0 million

FOSTER CITY, Calif., August 4, 2026 Qualys, Inc. (NASDAQ: QLYS), a leading provider of disruptive cloud-based IT, security and compliance solutions, today announced financial results for the second quarter ended June 30, 2026. For the quarter, the Company reported revenues of $182.2 million, net income under United States Generally Accepted Accounting Principles (“GAAP”) of $52.4 million, non-GAAP net income of $69.2 million, Adjusted EBITDA of $83.8 million, GAAP net income per diluted share of $1.50, and non-GAAP net income per diluted share of $1.98.
“In Q2, we continued to execute well, demonstrated by another quarter of solid revenue growth and profitability,” said Sumedh Thakar, Qualys’ president and CEO. “Qualys’ continuous innovation spanning AI for security and security for AI, growing AI-native Risk Operations Center adoption powered by our Enterprise TruRisk Management solution, a growing federal pipeline of new business opportunity, strong partner-led execution, and promising early QFlex engagement continue to reinforce the demand we’re seeing for a unified risk management platform that autonomously moves beyond theoretical exposure to validated, quantified, and remediated risk at the speed of modern attacks in multi-vendor environments. We believe these achievements not only advance our strong competitive differentiation but also sharpen the market opportunity ahead of us and bolster our confidence in reaccelerating long-term growth in the business.”

Financial Performance Outlook
Based on information as of today, August 4, 2026, Qualys is issuing the following financial guidance for the third quarter and full year fiscal 2026. The Company emphasizes that the guidance is subject to various important cautionary factors referenced in the sections entitled “Legal Notice Regarding Forward-Looking Statements” and “Non-GAAP Financial Measures” below.
Third Quarter 2026 Guidance: Management expects revenues for the third quarter of 2026 to be in the range of $185.5 million to $187.5 million, representing 9% to 10% growth over the same quarter in 2025. GAAP net income per diluted share is expected to be in the range of $1.43 to $1.50, which assumes an effective income tax rate of 21%. Non-GAAP net income per diluted share is expected to be in the range of $1.91 to $1.98, which assumes a non-GAAP effective income tax rate of 20%. Third quarter 2026 net income per diluted share estimates are based on approximately 35.0 million weighted average diluted shares outstanding for the quarter.
Full Year 2026 Guidance: Management now expects revenues for the full year of 2026 to be in the range of $732.0 million to $738.0 million, representing 9% to 10% growth over 2025. This compares to the previous guidance range of $721.0 million to $727.0 million. GAAP net income per diluted share is now expected to be in the range of $5.76 to $5.90, up from the previous guidance range of $5.40 to $5.61. This assumes an effective income tax rate of 21%. Non-GAAP net income per diluted share is now expected to be in the range of $7.74 to $7.88, up from the previous guidance range of $7.44 to $7.65. This assumes a non-GAAP effective income tax rate of 20%. Full year 2026 net income per diluted share estimates are based on approximately 35.2 million weighted average diluted shares outstanding.
Qualys has not reconciled non-GAAP net income per diluted share guidance to GAAP net income per diluted share guidance because Qualys does not provide guidance on the various reconciling cash and non-cash items between GAAP net income and non-GAAP net income (i.e., stock-based compensation, amortization of intangible assets from acquisitions and non-recurring items). The actual dollar amount of reconciling items in the third quarter and full year 2026 is likely to have a significant impact on the Company’s GAAP net income per diluted share in the third quarter and full year 2026. A reconciliation of the non-GAAP net income per diluted share guidance to the GAAP net income per diluted share guidance is not available without unreasonable effort.

Qualys will host a conference call and live webcast to discuss its second quarter financial results at 5:00 p.m. Eastern Time (2:00 p.m. Pacific Time) on Tuesday, August 4, 2026.

Legal Notice Regarding Forward-Looking Statements
This press release contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements generally relate to future events or our future financial or operating performance. Forward-looking statements in this press release include, but are not limited to, quotations of management and statements related to: the benefits of our existing, new and upcoming products, features, integrations, collaborations and joint solutions, and their impact upon our long-term growth; our expectations regarding AI for security and security for AI; our expectations regarding business opportunities with the federal government; our expectations regarding our business partners; our ability to advance our value proposition and competitive differentiation in the market; our ability to address demand trends; our ability to maintain and strengthen our category leadership; our ability to solve modern security challenges at scale; our strategies and ability to achieve and maintain durable profitable growth; our guidance for revenues, GAAP EPS and non-GAAP EPS for the third quarter and full year 2026; and our expectations for the number of weighted average diluted shares outstanding and the GAAP and non-GAAP effective income tax rate for the third quarter and full year 2026. Our expectations and beliefs regarding these matters may not materialize, and actual results in future periods are subject to risks and uncertainties that could cause actual results to differ materially from those projected. These risks include our ability to continue to develop platform capabilities and solutions; the ability of our platform and solutions to perform as intended; customer acceptance and purchase of our existing solutions and new solutions; real or perceived defects, errors or vulnerabilities in our products or services; our ability to retain existing customers and generate new customers; the budgeting cycles and seasonal buying patterns of our customers; our ability to maintain government authorizations applicable to our platform; general market, political, economic and business conditions in the United States as well as globally; our ability to manage costs as we increase our customer base and the number of our platform solutions; the market for cloud solutions for IT security and compliance not increasing at the rate we expect; competition from other products and services; fluctuations in currency exchange rates; unexpected fluctuations in our effective income tax rate on a GAAP and non-GAAP basis; our ability to effectively manage our rapid growth and our ability to anticipate future market needs and opportunities; and any unanticipated accounting charges. The forward-looking statements contained in this press release are also subject to other risks and uncertainties, including those more fully described in our filings with the Securities and Exchange Commission, including our Annual Report on Form 10-K and Quarterly Reports on Form 10-Q.
The forward-looking statements in this press release are based on information available to Qualys as of the date hereof, and Qualys disclaims any obligation to update any forward-looking statements, except as required by law.



Non-GAAP Financial Measures
In addition to reporting financial results in accordance with GAAP, Qualys provides investors with certain non-GAAP financial measures, including non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating income, non-GAAP net income, non-GAAP net income per diluted share, Adjusted EBITDA (defined as earnings before interest expense, interest income and other income (expense), net, income taxes, depreciation, amortization, and stock-based compensation) and non-GAAP free cash flows (defined as cash provided by operating activities less purchases of property and equipment, net of proceeds from disposal).
In computing non-GAAP financial measures, Qualys excludes the effects of stock-based compensation expense, amortization of intangible assets from acquisitions, non-recurring items and for non-GAAP net income, impairment of non-marketable securities and certain tax effects. Qualys believes that these non-GAAP financial measures help illustrate underlying trends in its business that could otherwise be masked by the effect of the income or expenses that are excluded in non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating income, non-GAAP net income, non-GAAP net income per diluted share, Adjusted EBITDA and non-GAAP free cash flows.
Furthermore, Qualys uses some of these non-GAAP financial measures to establish budgets and operational goals for managing its business and evaluating its performance. Qualys believes that non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating income, non-GAAP net income, non-GAAP net income per diluted share, Adjusted EBITDA and non-GAAP free cash flows provide additional tools for investors to use in comparing its recurring core business operating results over multiple periods with other companies in its industry.
Although Qualys does not focus on or use quarterly billings in managing or monitoring the performance of its business, Qualys provides calculated current billings (defined as total revenues recognized in a period plus the sequential change in current deferred revenue in the corresponding period) for the convenience of investors and analysts in building their own financial models.
In order to provide a more complete picture of recurring core operating business results, the Company’s non-GAAP net income and non-GAAP net income per diluted share include adjustments for non-recurring income tax items and certain tax effects of non-GAAP adjustments to achieve the effective income tax rate on a non-GAAP basis. The Company’s non-GAAP effective tax rate may differ from the GAAP effective income tax rate as a result of these income tax adjustments. The Company believes its estimated non-GAAP effective income tax rate of 20% in 2026 is a reasonable estimate under its current global operating structure and core business operations. The Company may adjust this rate during the year to take into account events or trends that it believes materially impact the estimated annual rate. The non-GAAP effective income tax rate could be subject to change for a number of reasons, including but not limited to, significant changes resulting from tax legislation, material changes in geographic mix of revenues and expenses and other significant events.
The presentation of this non-GAAP financial information is not intended to be considered in isolation or as a substitute for results prepared in accordance with GAAP. A reconciliation of the non-GAAP financial measures discussed in this press release to the most directly comparable GAAP financial measures is included with the financial statements contained in this press release. Management uses both GAAP and non-GAAP information in evaluating and operating its business internally and as such has determined that it is important to provide this information to investors.
