RBRK — Earnings Review Q3 FY26

Bear (PaulWBryant) | Date: 2026-02-22 | Quarter ended: Oct 31, 2025


First Look

I haven't written about Rubrik before. This is my first look, triggered by Q3 FY26 results (Dec 4, 2025) plus the pre-announced Q4 FY26 revenue figure of $342m disclosed during the Q3 call. The numbers tell a complicated story — a breakout quarter in Q3 followed by a guided deceleration in Q4 that deserves careful parsing.

Applying my framework cold.


Prior Beliefs / Updated Beliefs

Since this is my first analysis, I'll frame what I would have expected from a cloud-native data protection company 18 months post-IPO, then compare to what the numbers show.

Dimension What I'd Expect What the Numbers Show
Revenue growth 40-50% for a post-IPO cloud security play Q3: 48% YoY — on track. Q4 guided 33% — deceleration
ARR growth Should lead or match revenue ARR +34% YoY; reported revenue boosted by material rights (~$68m FY26) — normalized ≈35%
NRR Should be expanding if platform narrative is real Stuck at >120% for 5 consecutive quarters — floor, not ceiling
FCF Should be approaching positive $76.9m in Q3 (22% margin) — ahead of expectations
Gross margin >75% for cloud-native 80.5% [GAAP] — strong
SBC High post-IPO, should be declining as % of rev $83.2m in Q3 = 23.8% of revenue — not declining

Updated belief: The business is executing on cloud migration (ARR mix now 87% cloud) and hitting milestones. But the revenue growth story is muddied by material rights recognition, and the "growth is decelerating" signal is real regardless of normalization arguments.


Revenue Trajectory

Quarter Revenue ($m) YoY QoQ
Q4 FY24 (Jan-24) 159.0 +6.3%
Q1 FY25 (Apr-24)
Q2 FY25 (Jul-24) 191.0 +49.8%
Q3 FY25 (Oct-24) 221.5 +54.5% +16.0%
Q4 FY25 (Jan-25) 244.0 +53.5% +10.2%
Q2 FY26 (Jul-25) 297.0 +55.5% +11.8%
Q3 FY26 (Oct-25) 350.2 +48.3% +13.1%
Q4 FY26 (Jan-26) 342.0* +33.0%* -2.3%*

*Pre-announced; full results March 12, 2026.

The deceleration from 54-55% to 33% in one step looks alarming. But the honest number is normalized growth, which is approximately 35% (stripping the ~$68m in material rights recognition from FY26 cloud transformation contracts). ARR growth of 34% confirms this. So the normalized grower is running at ~35%, not 48% or 33%.

The sequential decline in Q4 (-2.3% QoQ) requires explanation. It's almost entirely the material rights reversal — those contracts boosted Q1-Q3 and don't repeat in Q4. ARR adds remain healthy (95minQ3, 96m implied in Q4).

Verdict on trajectory: Stable at ~35% normalized. Not accelerating, not collapsing. The reported figures are noisy; the ARR is honest.


ARR and Leading Indicators

Q2 FY25 (Jul-24) 919 63 678 74% >120%
Q3 FY25 (Oct-24) 1,002 83 769 77% >120%
Q4 FY25 (Jan-25) 1,093 91 876 80% >120%

Green flags:

Yellow flags:

On NRR: Five quarters at ">120%" is management telling me the precise number is uncomfortable to report. At 150% they were specific. At 120%+ they're not. I could be wrong — it might be 125% and they simply set a threshold. But I'd prefer the honest number.


Profitability and FCF Quality

Metric Q3 FY26 YoY Change
Gross Margin [GAAP] 80.5% +280bp
Op Margin [GAAP] -21.6% +31.2pp improvement
Non-GAAP Op Income $10.1m First positive ever
Non-GAAP EPS +$0.10 vs -$0.17 expected
FCF $76.9m (22.0%) +394% YoY
SBC $83.2m ~24% of revenue

The FCF number looks impressive until you set it next to SBC. $76.9m FCF, $83.2m SBC. On a truly diluted basis — treating stock compensation as the real cost it is — the company is generating essentially zero economic profit. The numbers have to match the theory, and the theory here is "first profitable quarter." On GAAP that's -$0.33 EPS. On non-GAAP it's +$0.10. The gap between those is largely SBC.

I don't dismiss non-GAAP metrics wholesale — they're useful for trend analysis. But 24% of revenue in SBC is not a rounding error. That needs to come down meaningfully before I'd call this a profitable company.

FCF guidance anomaly: Q1-Q3 FCF was already $212m vs full-year guide midpoint of $198m. So Q4 FCF is likely to be negative or near breakeven. That's a seasonal pattern (large renewals in Q4, billing cycle) but I'd want to hear management explain it on the Q4 call.

Gross margin at 80.5%: Clean. Expanding. This is what you want from a SaaS company — the unit economics are excellent.


Valuation

Metric Value Notes
Market Cap ~$10.2bn At ~$50/share (Feb 2026)
P/S (TTM) ~8.1x TTM revenue ~$1.26bn
P/S (FY26 guide) ~8.0x Guide $1,281m midpoint
P/S (FY27 estimate) ~5.6x Assuming ~30% growth to ~$1.7bn
ARR $1,443m Jan-26
EV/ARR ~6.1x Net cash ~$500m
SBC as % of Rev ~24% Dilution concern

At ~$50, RBRK is off ~50% from its 2025 highs. The valuation has compressed significantly. On 35% normalized growth with 80%+ gross margins, 8x forward P/S is not obviously expensive. Atlas pegged the PEG-equivalent at 0.26x vs CRWD at 0.60x — that spread is meaningful.

But I need to flag: this math improves materially by FY27 only if growth holds. The FY27 framework from management (given on the Q3 call) says: normalized revenue growth to exceed ARR growth (~34%), modest contribution margin improvement, modestly higher FCF. That's a 35-38% revenue grower in FY27. If delivered, forward P/S of 5-6x is cheap. If ARR growth decelerates into the low-20s (as the NRR trend could imply), the picture changes.

Every business is a sell at some price. At ~50, the price is fair, not obviously a gift.


Product and Competitive Position

Items the transcript highlighted that I want to track:

Identity business: ~$20m ARR, customer count doubled in Q3, 40% of new identity customers are net-new to Rubrik. This is the real optionality — if Rubrik becomes the identity resilience layer the way it became the data protection layer, ARR could accelerate. But $20m out of $1,347m is 1.5% of sub ARR. It's a seed, not a harvest yet.

Rubrik Agent Cloud (beta): Monitor, govern, remediate enterprise AI agents. Integrations with Microsoft Copilot Studio and AWS Bedrock. Early, but Rubrik is positioning at the intersection of cyber resilience and AI governance. I find this credible — the data protection moat extends naturally to AI data and agent behavior.

Cohesity-Veritas merger: Atlas notes these two legacy players combined at $1.5bn ARR are preparing a 2026 IPO. That's a unified competitive response to Rubrik's cloud-native advantage. I'd watch this closely — Rubrik's cloud ARR growth (53% YoY) suggests it's winning the migration battle, but a combined, well-funded legacy player changes the competitive math.


Prior Beliefs / Updated Beliefs Summary

Belief Going In Reality Updated View
35-40% normalized grower ~35% normalized — correct Confirmed
FCF inflecting positively $77m Q3, ahead of schedule Better than expected
NRR should expand as platform expands Stuck at >120%, 5 quarters Not yet. Watching
SBC would start declining Still 24% of revenue Disappointing
Material rights headwind understood ~$68m in FY26, FY27 cliff Need FY27 guide on March 12
Identity is small but real $20m ARR, accelerating Confirmed small, accelerating

Management Accountability

Promises made on Q3 call:

  1. Q4 revenue $341-343m → Delivered: $342m ✓ (confirmed pre-announced)
  2. FY26 ARR $1,439-1,453m → Actual $1,443m ✓
  3. FY26 FCF $194-202m → Q1-Q3 = $212m (already exceeded midpoint; Q4 likely weak)
  4. FY27 framework: normalized rev > ARR growth, modest margin improvement, modestly higher FCF → Track on March 12 call

To watch on March 12:


Conclusion

RBRK is a well-run business at an interesting valuation. The numbers show:

At ~$50 and 8x forward P/S, the stock is priced for continued execution, not heroics. The March 12 Q4 FY26 report is the real test: management has to show FY27 guidance that confirms 35%+ normalized growth. If they guide 25-28%, the thesis weakens materially. If they guide 35%+, this looks interesting.

I don't invest based on hope, and I haven't built conviction through prior quarters watching this business. My discipline says: wait for the FY27 guide. After March 12, I'll have the data I need to size a position or pass.

Action: Watch. No position yet. Re-evaluate after March 12 Q4 report.
