FFIV · Q1 2026 Earnings

F5, Inc.

Reported January 27, 2026

30-second summary

F5 reported Q1 revenue of $822M (+7% YoY), beating the $730–780M guide by $42–92M, with non-GAAP EPS of $4.45 vs. $3.35–3.85 guided — a 16–33% beat. Management raised FY26 revenue growth to 5–6% from 0–4% and FY26 non-GAAP EPS to $15.65–16.05 from $14.50–15.50, retiring the EPS-decline guide from October. The October security incident, which dominated the Q4 narrative and forced the wider-than-typical Q1 range, produced "minimal demand disruption" — the cautious framework that defined last quarter's brief is gone.

Management tone

Narrative arc: Hardware reacceleration → Non-refresh secular story → Security incident damage control → AI inflection + regulatory tailwind.

AI moved from production-deployment language to inflection-disclosure. From the prepared remarks: "In Q1, we added nearly as many AI customers as we did in all of FY25." In Q&A, Francois added that the FY25 mix was oriented toward data delivery, while Q1's adds were "almost balanced between data delivery and security" — runtime security demand is now matching the original load-balancing/throughput motion. That sentence reframes AI from a multi-year build to a now-quarter motion, and explains why management felt comfortable raising the FY revenue growth guide by 150–200bps a single quarter after cutting it.

Hybrid multi-cloud framing shifted from cost-optimization narrative to regulatory mandate. From the call: "Regulations like NIST 2, DORA, cyber resilience regulations…are really causing reinvestment in data center and stronger resilience between data center and the cloud." This is a meaningful tone shift — the demand thesis moves from discretionary capex to compliance-driven spend, which is structurally less cyclical and harder to defer, and management explicitly tied EMEA's +24% growth quarter to it.

The security incident has been fully reframed from existential risk to relationship lever. This quarter: "We experienced minimal demand disruption in Q1…Unexpected positive outcomes emerged, including customers gaining a deeper understanding and appreciation of F5's critical role in their infrastructure and opportunities to strengthen relationships, including deeper engagement with CISOs." In Q&A, Francois disclosed that the install base on the latest software release moved from ~15% a year ago to over 50% today — customers used the patch event to step up. The pivot from damage-control to expanded-CISO-engagement inside 90 days is the cleanest evidence that the Q4 guide was conservative rather than realistic.

The Systems story sharpened from refresh-cyclicality to refresh-plus-expansion. "This refresh cycle obviously is stronger than past refresh cycles because what we are seeing is not just refresh, but a lot of expansion for customers…customers are also getting their infrastructure ready for AI." Management is now arguing the +37% Systems growth has two structural drivers (AI capacity, compliance) layered on top of refresh.

Hedging language is still present but pointed at specific risks rather than demand. Management flagged rising memory costs hitting product COGS in H2 and lowered the FY gross margin low end by 50bps as a result. In Q&A, Francois walked through an early-action supply playbook (raised forecasts months ago, qualified additional suppliers, broker buys) and noted no decommits but "substantial price increases." Demand confidence is up; component cost confidence is down.

Recurring themes management leaned on this quarter:

AI production deployment requiring infrastructure upgrades for data delivery and runtime securityRegulatory-driven digital sovereignty accelerating hybrid multi-cloud architectures outside USSystems refresh-plus-expansion cycle driven by AI readiness and compliance requirementsConverged platform consolidation as customers replace fragmented point solutionsGovernment sector strength from federal adoption and sovereignty concernsSoftware adoption steady with strong renewal cohorts providing confidence in mid-single-digit growth

Risks management surfaced:

Rising memory costs impacting gross margins in second half of FY26Potential supply constraints and memory component availability despite mitigation actionsSecond half growth deceleration implied by guidance (4-5% vs 7% H1)Timing and enforcement uncertainty around new cyber resilience regulationsMacro fluidity and budget finalization dynamics in coming quarters

Answers to last quarter's watch list

Q1 FY26 revenue landing above the $755M midpoint. Q1 printed $822M — $67M above the midpoint and $42M above the $780M high end. This validates the H1-concentrated, H2-normalize narrative management drew last quarter, and explicitly confirms incident disruption was lower than the bridge implied.
Resolved positively
Whether software growth recovers above +5% YoY. Software declined -8% YoY in Q1 against an exceptionally strong Q1 FY25 comp (eight-figure renewal plus strong perpetual SP deals). Management reiterated the FY26 mid-single-digit software framework, citing a strong renewal cohort and healthy utilization rates for the balance of the year. The new-deal portion was not separately sized. Status: Resolved negatively in-period; FY framework reaffirmed
Q1 non-GAAP operating margin holding above 32%. Q1 printed 38.2%, well above the 32% floor and above the raised FY 34–35% guide. Back-half leverage assumptions are intact with significant cushion.
Resolved positively
Number of customers reporting sensitive data exfiltration. Management stated no evidence of any customer being breached as a result of the incident and that no customer has reported such an incident to F5. Status: Resolved positively, continue monitoring through any 10-Q or 10-K disclosure
Whether multi-year software agreements continue at +20% YoY pace. F5 did not call out the multi-year software agreement growth rate in this quarter's disclosed materials. With software down -8%, this leading indicator is the one we'd most want to see — its absence is itself a tell.
Not resolved
Federal segment recovery from government shutdown drag. Cooper disclosed government customers represented 23% of Q1 product bookings, including 8% from U.S. Federal — a healthy print, but no YoY comparison was offered. Management cited "government sector strength from federal adoption and sovereignty concerns" qualitatively.
Continue monitoring

What to watch into next quarter

Whether software revenue returns to positive YoY growth in Q2. Subscription software was +1% YoY at $164M in Q1; total software was held down by a tough perpetual comp. A second quarter of total-software decline against the FY26 mid-single-digit framework would force a mid-year reset of the software narrative.

Q2 non-GAAP gross margin landing inside the 82.5–83% guide. The low end stepped down from Q1's guide and the FY range widened to the downside on memory costs. A miss here would confirm component-cost pressure is structural rather than a one-quarter timing item.

Whether AI customer adds in Q2 maintain the Q1 pace. Management's "as many AI customers in Q1 as in all of FY25" is the cleanest forward indicator on the call. A flat or declining add count would suggest the inflection is more pull-forward than run rate. Watch also the data-delivery vs. security mix that Francois flagged as balancing for the first time this quarter.

Systems revenue holding the Q1 run rate. Q1 Systems at $218M (+37%) is the engine driving the FY guide raise. A material reversion would mechanically pressure the 5–6% FY revenue growth guide.

Any update on the multi-year software agreement growth rate. This was the cleanest platform-stickiness signal in Q4. Two consecutive quarters of non-disclosure against deteriorating headline software revenue is the data point we'd most want clarified.

H2 implied growth trajectory. Q1 +7% and Q2 guide of ~7% at midpoint, against the FY guide of 5–6%, implies H2 deceleration — watch whether the memory-cost margin pressure and the H2 software reacceleration framework hold as the year progresses.
