Why did F5's raised guidance matter to investors?

The upgrade to FY2026 revenue growth (9%-10% from 7%-8%) and non-GAAP EPS ($17.21-$17.33 from $16.25-$16.55) signals that Q3's strength is expected to carry into Q4 and that management has more confidence in demand. Q4 revenue guidance of $870-$890 million implies continued double-digit product momentum, though investors should weigh the company's history of guidance adjustments against the magnitude of the raise.

How much of the growth came from Systems versus Software and Services?

Systems was the standout, growing 32% to $240 million. Software grew 7% to $223 million, and Services grew a more modest 3% to $402 million. Because Services is the largest and most recurring revenue stream, its slower growth is worth monitoring even as hardware-related Systems sales accelerate.

Why is there a gap between GAAP and non-GAAP profitability?

The gap is mainly driven by stock-based compensation ($65.5 million in Q3), amortization of acquired intangibles, acquisition-related charges ($10.1 million), and cyber incident costs ($3.0 million). The company also reported $5.3 million in insurance recoveries that partially offset cyber costs. GAAP operating margin actually declined to 24.7% from 25.2%, which investors should consider alongside the non-GAAP improvement.

Are there risks investors should watch in this report?

Yes. Inventory increased to $127 million from $77 million, which may reflect Systems demand but could also signal supply or demand risk if sales slow. The company continues to disclose a cyber incident and related costs. Its guidance excludes future acquisition charges, cyber costs, and restructuring, which management describes as highly variable, so GAAP results could differ materially from non-GAAP outlook.

How is F5 deploying its cash?

F5 generated $841 million in operating cash flow over nine months and spent $501 million on share repurchases, along with $64 million in capital expenditures and $48 million on acquisitions. Cash and equivalents rose to $1.61 billion. Continued buybacks alongside rising deferred revenue ($2.19 billion in total, up from $2.00 billion) suggest a balanced approach to capital return and growth investment.

FFIV 8-K: Earnings & Results

01—Abstract

Summary

Summary of the 8-K filed July 27, 2026. Cited figures are marked; the original filing is the authoritative source.

F5, Inc. (NASDAQ: FFIV) reported fiscal third-quarter 2026 results (quarter ended June 30, 2026) that were strong on the top line and raised its full-year outlook.

Total revenue rose 11% year over year to $865 million^a (from $780 million), led by Systems revenue of $240 million (up 32%) and Software revenue of $223 million (up 7%), while Services grew 3% to $402 million. Management highlighted 19% product revenue growth and eight consecutive quarters of double-digit product growth, attributing demand to F5's application delivery and security platform as AI-driven threats and hybrid multicloud environments expand. Note that the press release's headline product growth and the segment breakdown in the narrative (Systems plus Software) reconcile to the reported product line of $463 million, up roughly 19% from $389 million.

Profitability was solid on a non-GAAP basis: non-GAAP gross margin expanded to 84.2% from 83.1%, non-GAAP operating margin rose to 35.0% from 34.3%, and non-GAAP diluted EPS grew 14% to $4.73^b from $4.16. On a GAAP basis, operating margin contracted to 24.7% from 25.2%, and diluted EPS rose to $3.62 from $3.25, with the gap driven largely by higher stock-based compensation ($65.5 million vs. $57.5 million), acquisition-related charges ($10.1 million vs. $2.0 million), and cyber incident costs ($3.0 million, partly offset by $5.3 million of insurance recoveries). Cash generation remained strong, with nine-month operating cash flow of $841 million (up from $742 million) and $501 million in share repurchases, while cash and equivalents reached $1.61 billion.

Inventory rose sharply to $127 million^c from $77 million, consistent with the Systems growth. Management raised FY2026 guidance to 9%-10% revenue growth (from 7%-8%) and non-GAAP EPS of $17.21-$17.33 (from $16.25-$16.55).

Q4 guidance calls for revenue of $870^d-$890 million and non-GAAP diluted EPS of $4.14-$4.26. Investors should note that the company discloses a cyber incident in its non-GAAP adjustments, which remains a monitored item, and that the guidance excludes future acquisition-related charges, cyber costs, and restructuring, which the company cautions can be material and hard to forecast.
