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.
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 | $83.2m in Q3 = 23.8% of revenue — not declining |
Updated belief: The business is executing on cloud migration (ARR mix now 87% cloud) and hitting milestones. But the revenue growth story is muddied by material rights recognition, and the "growth is decelerating" signal is real regardless of normalization arguments.
| Quarter | Revenue ($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 ~$68m in material rights recognition from FY26 cloud transformation contracts). ARR growth of 34% confirms this. So the normalized grower is running at ~35%, not 48% or 33%.
The sequential decline in Q4 (-2.3% QoQ) requires explanation. It's almost entirely the material rights reversal — those contracts boosted Q1-Q3 and don't repeat in Q4. ARR adds remain healthy (95minQ3, 96m implied in Q4).
Verdict on trajectory: Stable at ~35% normalized. Not accelerating, not collapsing. The reported figures are noisy; the ARR is honest.
| Quarter | Sub ARR ($m) | ARR Add | Cloud ARR | Cloud % | NRR |
|---|---|---|---|---|---|
| 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% |
| Q1 FY26 (Apr-25) | 1,181 | 88 | 972 | 82% | >120% |
| Q2 FY26 (Jul-25) | 1,252 | 71 | 1,064 | 85% | >120% |
| Q3 FY26 (Oct-25) | 1,347 | 95 | 1,175 | 87% | >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.
| 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.
| 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.
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.
| 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 |
Promises made on Q3 call:
To watch on March 12:
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.
