Qualys Earnings Report: Q1 Revenue Up 10%, Full-Year Outlook Lifted

The news: Qualys, the cloud-based security and compliance software provider, published its first-quarter 2026 earnings report on May 5, 2026. Revenue rose 10% from a year earlier to $175.6 million, and the company raised its full-year revenue and earnings-per-share guidance.

By the numbers:

• Revenue: $175.6 million, up 10% year over year
• GAAP net income: $50.6 million, or $1.42 per diluted share
• Non-GAAP net income: $69.6 million, or $1.95 per diluted share
• Adjusted EBITDA: $83.3 million
• 2026 revenue guidance: $721.0 million to $727.0 million, up from $717.0 million to $725.0 million
• 2026 GAAP EPS guidance: $5.40 to $5.61, up from $5.20 to $5.48
• 2026 non-GAAP EPS guidance: $7.44 to $7.65, up from $7.17 to $7.45

Why it matters: Qualys is one of the more profitable mid-sized names in security software. Adjusted EBITDA of $83.3 million on $175.6 million of revenue works out to a margin of roughly 47%, a level that shapes how the company is compared with faster-growing but less profitable peers. The guidance change was asymmetric: the low end of the revenue range rose by $4 million and the top by $2 million, tightening the band. Earnings guidance moved more than revenue guidance, which points to expectations of continued cost control. The spread between GAAP EPS of $1.42 and non-GAAP EPS of $1.95 reflects items excluded from the adjusted measure, which the company reconciles in its release.

The big picture: Ten percent growth places Qualys in the steady, rather than hypergrowth, tier of the cybersecurity market. Its quarterly results tend to be read for signs of whether demand for vulnerability management and compliance tools is holding up as enterprise security budgets are spread across more vendors and categories. The company’s chief executive, Sumedh Thakar, said the results reinforced confidence in durable, profitable growth. Its net income line also stands out: GAAP net income of $50.6 million equaled nearly 29% of revenue.

What’s next: For the second quarter, Qualys guided to revenue of $177.5 million to $179.5 million, which it said represents growth of 8% to 9%, along with GAAP EPS of $1.24 to $1.31 and non-GAAP EPS of $1.73 to $1.80. That implies a modest deceleration from the first quarter’s 10% pace. Investors following the next earnings report will be watching whether revenue lands inside that range and whether the company again adjusts its full-year outlook.
