Date: 2026-03-14 Quarter: Q4 FY26 (ended Jan 31, 2026) Reported: March 12, 2026 Market cap: ~$11.6B | P/S: ~7.7x run-rate | Revenue growth: 46% YoY reported (43% ex-material rights) Second analysis of RBRK. First review: Q3 FY26 (Feb 2026).
Alright, here's the deal. Back in February I wrote my first-ever look at Rubrik and called the thesis "Weakening." That wasn't because the business stunk — it was because NRR was stuck at 1.20 for five quarters, growth was decelerating, and the platform expansion stuff (Identity, Agent Cloud) was still immaterial. I said I'd give it one more quarter before sizing. That quarter was Q4 FY26.
And Q4 just cleared every bar I set.
Revenue of $377.7M crushed the $341-343M guide by 10.4%. Net new subscription ARR hit 115M—arecordthatblewpastevenmybullcaseof 96M. FCF for the full year came in at $237.8M versus the $194-202M guide. Second straight quarter of non-GAAP profitability. Record $1M+ customer adds (32 in the quarter). And then they dropped FY27 guidance that, if you squint even a little, is clearly sandbagged.
Here's how I'm thinking about this: the "is" column got a lot longer, and the "could be" column got more credible. That's exactly the kind of shift that earns a company a promotion from tryout to starter.

I said there were five things I needed to see. Let me grade them honestly.
| What I Wanted | Result | Grade |
|---|---|---|
| ARR at top of $1.439-1.453B range | $1.462B — beat the top by $9M | A |
| NRR movement from 1.20 | Still 1.20. Six quarters now. | C |
| FY27 guide showing 35%+ growth | 27-28% normalized. Below my bar. | B- |
| Identity ARR reaching $30M+ | No specific disclosure. Called "fastest-growing" and "exceeded expectations." | Incomplete |
| FCF Q4 well above guide | $237.8M FY vs $202M guide. Beat by $36M. | A |
So I got three out of five clearly positive, one unchanged (NRR), and one I can't grade because they didn't give me the number. That's better than I expected — especially the net new ARR acceleration and ARR beat. The FY27 guide at 27-28% normalized is below my desired 35%, but let me explain why I'm less worried about that than I was three weeks ago.
This was a textbook beat-and-raise, which is the gold standard in my framework.
The beat:
The raise (initial FY27 guide):
Here's the thing about the FY27 guide being "only" 27-28% growth. Look at Rubrik's sandbagging track record:
If you apply even half of FY26's beat magnitude, FY27 revenue lands at $1,700M+ and ARR at $1,900M+. Net new ARR guided at $372M (flat YoY) after they just doubled it. Classic sandbag. Management is setting a bar they know they'll clear.
I could be wrong about this — maybe the macro gets worse, maybe the CRO transition causes a hiccup. But the pattern of underpromise-and-overdeliver is now three years deep. I'm going to trust it.
This section got a lot longer since my Q3 review.
Record bookings engine. $115M net new ARR is not a fluke — it's a sequential acceleration from $95M in Q3 and $91M in Q4 FY25. 32 new $1M+ customers (up >50% YoY). The enterprise motion is working. These are large, multi-year, sticky contracts.
Cash flow machine is real. FY26 FCF of $237.8M on $1.32B revenue is an 18% FCF margin. A year ago this company was barely FCF positive. Now it's generating $238M. FY27 guide of $270M (which will likely be $310M+ if the sandbagging continues). This is no longer a "path to profitability" story — profitability arrived.
Gross margins are best-in-class. 83.7% non-GAAP gross margin. That's up from 79.7% a year ago. Cloud mix at 88% is driving pure software economics. I'd expect this to keep climbing toward 85%+ as the remaining on-prem ARR ($172M) rolls off.
Win rate > 90%. The CEO repeated this twice. Against legacy data protection vendors — Veritas, Commvault, Dell — Rubrik wins north of 90% of the fights it's in. That's a moat in action.
Operating leverage inflecting. ARR contribution margin went from 2.1% to 11.6% in one year. FY27 guide is ~13%. The operating model is scaling.
SBC declining. 22.5% of revenue, down from 33.3% a year ago. Still elevated, but the trend is clearly in the right direction. Share count is 201M, up only 6.8% YoY (post-IPO dilution normalizing).
Identity: graduated from "could be" to "early is." The CEO explicitly said identity was "the fastest-growing product" that "exceeded our expectation of how fast the product has scaled." They didn't give me a specific ARR number (which I wanted), but the qualitative commentary is strongly positive. Identity went from proof-of-concept to scaled product. At $20M ARR in Q3, even a doubling would still be small relative to $1.46B total — but the trajectory matters. I'm upgrading this from "immaterial" to "early positive contributor."
Agent Cloud: still a "could be" but now a real product. Rubrik Agent Cloud went GA in Q4. It integrates with Amazon Bedrock AgentCore and Microsoft Copilot Studio. The CEO described three phases of customer engagement: (1) inventory — how many agents do I have? (2) monitoring — what are they doing? (3) control — real-time dynamic guardrails. That's a logical product progression. But as the CEO himself said, "everybody with a mother is jumping into this market." Agent Cloud is speculative. I'm not paying for it in my valuation, but I acknowledge it extends the growth runway if it works.
Sovereign Cloud: new but niche. Launched in response to geopolitical data sovereignty concerns. Interesting optionality, not a needle-mover yet.
NRR still stuck at 1.20. Six consecutive quarters now. I've been watching this since my first review, and it hasn't budged. Here's where I've evolved my thinking: in the context of $115M record net new ARR, 32 new $1M+ customers, and the identity product exceeding expectations, the NRR flatline is more of a math problem than a demand problem. Identity is still <2% of total ARR — it can't move the blended NRR number yet. When it reaches $50M+ (maybe by FY27 end), it should start showing up.
That said, I have a bright line. If NRR drops below 120%, I'm out. No "one more quarter" rationalization. That would mean expansion is failing to offset churn, and the platform thesis crumbles.
Revenue deceleration is real, even if sandbagged. Reported growth: 51% -> 48% -> 46% across Q2-Q4 FY26. Guided 27-28% for FY27. Even normalized, this is a company decelerating from the mid-40s to the high 20s. That's natural at $1.3B in revenue, and the net new ARR acceleration suggests the deceleration is less bad than the headline implies. But I need to be realistic — this isn't going back to 50%.
CRO transition is an execution risk. Jesse Green was promoted to global CRO from running Americas. Management says it was planned three years ago — "CRO in training." That's reassuring. But go-to-market leadership changes can create pipeline disruptions. Q1 FY27 will be the first quarter under the new CRO. I'll watch net new ARR closely.
Dilution and SBC. Better, not solved. SBC at $329M for the full year (25% of revenue) on a company generating $238M in FCF means shareholders are funding a significant portion of employee comp. The trend is right (33% -> 22.5% by Q4), but it needs to get below 20% in FY27 to be truly comfortable.
Cohesity-Veritas in the rearview. $1.5B ARR, 28% margins, IPO prep. They're the real competitor — not the legacy vendors Rubrik is beating 90%+ of the time. When Cohesity-Veritas goes public in 2026, the competitive narrative will get louder.
| Metric | Value |
|---|---|
| Stock price | ~$57.50 |
| Market cap (~201M shares) | ~$11.6B |
| Net cash ($1.68B cash - $1.13B converts) | ~$545M |
| EV | ~$11.0B |
| Run-rate revenue (Q4 x 4) | ~$1.51B |
| EV / Run-rate revenue | 7.3x |
| EV / ARR ($1.46B) | 7.5x |
| P/FCF (FY26 actual $238M) | ~49x |
| P/FCF (FY27 guide $270M) | ~43x |
| P/FCF (FY27 likely ~$320M) | ~36x |
For a company growing 28%+ normalized with 84% gross margins, FCF margin approaching 20%, and improving operating leverage, 7.3x EV/revenue is reasonable. Not cheap enough to back up the truck, but reasonable enough to own.
For context: CrowdStrike trades at roughly double the EV/revenue multiple with lower growth. That's not a perfect comp — CRWD has better profitability and a more proven platform — but it illustrates that RBRK isn't priced for perfection here. There's room for the market to re-rate this higher as profitability scales.
Is: Core data protection (1.46BARR), cloudtransition(88238M), operating leverage (ARR contribution margin 11.6%), win rate (>90%), enterprise adoption (2,805 $100K+ customers, 32 $1M+ adds). This is a real business executing at a high level.
Early Is (upgraded from "Could Be"): Identity product. Fastest-growing in the portfolio, exceeding internal expectations. Still small but trajectory is convincing.
Could Be: Agent Cloud (GA but pre-revenue at any scale), Sovereign Cloud (new product, niche).
The balance has shifted materially toward "is." Three months ago I said the core business was delivering but the platform thesis was unproven. Today, the core business delivered even more emphatically, and the platform thesis got its first real proof point in identity exceeding expectations. That earns a promotion.
Prior thesis (Q3 FY26): Weakening (first look, baseline) "Core data protection is executing. But NRR stuck at 1.20, growth decelerating, platform expansion products still immaterial."
Updated thesis: Intact
I'm upgrading from Weakening to Intact. Here's what changed:
What didn't change: NRR still at 1.20. This prevents me from going to "Strengthening." I need NRR to move before I'll say this is getting better. But the weight of evidence now favors the bull case more than the bear case.
Prior recommendation: Tryout (2-4%) — waiting on Q4
New recommendation: Starter (5-8%)
RBRK earned its promotion. The quarter answered every question I had except NRR, and even on NRR I now have a reasonable explanation (identity too small to move the blended number). A starter position at 5-8% is appropriate for a company at this stage — executing well, reasonable valuation, with identifiable risks that keep me from going to a full-conviction 10%+ position.
I'd build the position in stages. Start at 5%, add to 8% if Q1 FY27 shows continued net new ARR strength (>$85M) and no CRO disruption.
| Metric | Bull | Bear | My Base |
|---|---|---|---|
| Q1 revenue | >$395M | <$365M | $385-395M |
| Net new ARR | >$95M | <$80M | ~$88-92M (seasonal dip OK) |
| NRR | Any improvement | <120% (sell trigger) | Stable 120% |

Sell triggers (non-negotiable):
| Item | Prior (Q3 Review) | Updated (Q4) | Change |
|---|---|---|---|
| Revenue trajectory | "Deceleration can't be fully explained by material rights" | +46% YoY, 10.4% beat. Deceleration is real but sandbagged. | More confident |
| Net new ARR | "Record $94M" | $115M — record by 22%. Acceleration, not deceleration. | Significantly better |
| FCF | "FCF inflection is real" | Confirmed: $238M vs $202M guide. Three years of FCF sandbags. | Confirmed |
| NRR | "Five quarters at 1.20. Key concern." | Six quarters at 1.20. Context now suggests math problem, not demand problem. | Still watching but less concerned |
| Profitability | "First non-GAAP profitable quarter" | Second consecutive. FY27 guided non-GAAP profitable for full year. | Confirmed |
| Identity | "Intriguing but immaterial. $20M ARR." | "Fastest-growing product," "exceeded expectations." Upgraded to early positive. | Materially better |
| Agent Cloud | "Pre-revenue, deeply 'could be'" | Now GA. Integrating with Bedrock + Copilot Studio. Still 'could be' but now a real product. | Slightly better |
| Position sizing | "Tryout (2-4%), waiting on Q4" | Starter (5-8%). Q4 cleared the bar. | Promoted |
| Thesis | "Weakening (first look, baseline)" | Intact. Upgraded. | Stronger |
| Dilution | "Real problem. SBC 24% of revenue." | Improving. SBC 22.5% of revenue, down from 33%. Still elevated. | Better |
Management made the following forward commitments on the Q4 FY26 call:
| Promise | Quarter Made | What to Verify |
|---|---|---|
| FY27 revenue $1,597-1,607M | Q4 FY26 | Q1 FY27 earnings (~June 2026) |
| FY27 sub ARR $1,829-1,839M | Q4 FY26 | Q1 FY27 raise magnitude |
| FY27 FCF $265-275M | Q4 FY26 | Cumulative progress through year |
| FY27 non-GAAP EPS $0.07-0.27 | Q4 FY26 | Q1 FY27 profitability |
| ARR contribution margin ~13% | Q4 FY26 | Quarterly progression |
| CRO transition "very natural and easy" | Q4 FY26 | Q1 FY27 pipeline and net new ARR |
| Legacy replacement "very early" | Q4 FY26 | Win rate sustainability |
| Identity "exceeded expectations" | Q4 FY26 | ARR disclosure, continued momentum |
Atlas (wsm) upgraded to "Strengthening" and scored this as the best quarter in company history. I'm broadly aligned on the facts but more measured on the conclusion.
Rubrik delivered a quarter that answered the question I was asking: is this a company decelerating into irrelevance, or a company sandbagging its way through a natural growth moderation while the bookings engine accelerates underneath? The answer is clearly the latter.
$115M record net new ARR. $238M in FCF. Second consecutive profitable quarter. 32 new $1M+ customers. 83.7% gross margins. Win rate >90%. Identity exceeding expectations. And a FY27 guide that — based on three years of 8-14% beat patterns — will be meaningfully exceeded.
The market's sleeping on this one because of "AI eating software" angst and an optically decelerating growth rate inflated by material rights noise. The normalized picture is a 28% grower trading at 7.3x EV/revenue with improving profitability and a credible path to $300M+ FCF. That's a good deal.
NRR is the one thing keeping me from higher conviction. Six quarters at 1.20 is not a coincidence, and until it moves, the platform thesis has an asterisk. But everything else is firing, and the balance of evidence has shifted. RBRK earns a starter position.
As usual, thanks for reading.
