Introduction

Qualys delivered a strong second-quarter 2026 performance, reporting double-digit revenue growth and upgrading its full-year outlook. The cybersecurity firm leveraged margin expansion and cash flow momentum to signal confidence in its trajectory.

What Happened

For the quarter ending August 4, Qualys posted $182.2 million in revenue, an 11% year-over-year increase. GAAP operating income rose 20% to $61.9 million, pushing the operating margin to 34%, up from 31% a year earlier. Non-GAAP operating income climbed 16% to $81.4 million, yielding a 45% margin, while adjusted EBITDA increased 14% to $83.8 million at a 46% margin. Perhaps most notably, operating cash flow surged 77% to $59.6 million from $33.8 million, boosting cash generation as a share of revenue to 33% from 21%. On the earnings front, full-year non-GAAP EPS guidance was raised to a range of $7.74-$7.88, and GAAP EPS guidance was set between $5.76 and $5.90.

Why This Matters

The guidance raise reflects management's confidence despite a deliberate slowdown in projected growth rates. Third-quarter revenue expectations of $185.5 million to $187.5 million imply 9% to 10% growth, stepping down from the 11% posted in Q2, and the full-year outlook was adjusted to a 9% to 10% expansion range. The gap between GAAP and non-GAAP results widened, with net income of $52.4 million under GAAP compared to $69.2 million on a non-GAAP basis, driven by accounting adjustments. The company also secured a FedRAMP High Authorization for its TotalCloud platform, sponsored by the U.S. Drug Enforcement Administration, opening federal and regulated-market opportunities. Additional announcements included a Converge partnership tied to cyber insurance discounts, four international ROCon customer events, and Frost and Sullivan recognition in cloud and application runtime security.

Key Takeaways

  • Revenue grew 11% year-over-year to $182.2 million, surpassing the $182 million threshold
  • Full-year revenue guidance upgraded to $732 million-$738 million, up from $721 million-$727 million
  • Operating margins expanded across both GAAP and non-GAAP metrics
  • Operating cash flow surged 77%, signaling stronger cash conversion
  • Non-GAAP EPS guidance raised to $7.74-$7.88; GAAP EPS seen at $5.76-$5.90
  • FedRAMP High Authorization broadens addressable market into federal sector
  • Hedge fund ownership held steady at 34 funds; short interest sits at 16.17% of the float
  • Stock trades at a forward P/E of 20.62, reflecting market skepticism about sustaining the growth pace
  • Management emphasizes QFlex and the federal pipeline as next catalysts for booking momentum

Conclusion

Qualys entered the second half of 2026 with reinforced financial strength, expanded federal reach, and upwardly revised expectations, yet the narrowed growth guidance and elevated short interest indicate the market remains watchful about sustaining the momentum. Whether the company can translate product announcements and federal contracts into consistent bookings will likely determine if the current growth trajectory can be maintained through the remainder of the year.
