RBRK — Q3 FY26 Earnings Review (Saul)

Date: 2026-02-22 Quarter: Q3 FY26 (ended Oct 31, 2025) Reported: December 4, 2025 Next earnings: Q4 FY26, March 12, 2026


Verdict

Rubrik is a genuinely impressive cloud-native data protection company in the middle of a real profitability inflection. The Q3 numbers were outstanding on every profitability and cash metric. But I have to be honest — the NRR has been stuck at exactly 120% for five straight quarters, and revenue growth is decelerating from 55% to a guided 33% in Q4 (or ~35% normalized). Those two facts together give me pause. This is a Hold, not a Buy, for me right now. I want to see Q4 earnings on March 12 and especially the FY27 guide before adding conviction.

Revenue Growth Trajectory

Let me be direct about this. Revenue deceleration is the thing I always watch most carefully. Here's the trajectory:

That is meaningful deceleration. Now, the company explains ~$68M of FY26 revenue as non-recurring "material rights" from their cloud transformation contracts. Strip that out and normalized growth is ~35% — better. And the ARR growth has been remarkably stable: 33-36% every quarter. So there are two stories here: the revenue number is messier than the underlying business.

But I have to respect what I see. A guided 33% growth rate is not the exceptional growth I require for a top position. I need 40%+ consistently. This company had it — it just doesn't have it right now. That matters.

The counter-argument, which I take seriously: net new subscription ARR of $94M in Q3 was a record. The $1M+ customer adds (23 in a quarter!) were a record. Cloud ARR growing 53% with 87% mix means the high-quality recurring part of the business is healthy. So is this a business in trouble? No. Is it a business I'd put 15-20% of my portfolio in today? Also no.


The NRR Problem

This is what I keep coming back to. Net retention rate at exactly 120% for five consecutive quarters.

NRR of 120% means existing customers are growing spending 20% per year on average. That's fine — good, even. But it was 149% two years ago. It has declined every quarter since then, and now it's flatlined. Five straight quarters at exactly 120%.

What does this tell me? Two things, and one is better than the other:

  1. (Good) The company has stabilized churn. They're not losing customers at an accelerating rate.
  2. (Concerning) The new products — identity, security features — are not yet driving meaningful expansion in existing accounts at scale. $20M in identity ARR is nice but it's not moving the NRR needle.

For a SaaS company, I want to see NRR above 120% AND ideally expanding. Flat NRR at 120% is sustainable but it means growth must come from new customer acquisition, which is more expensive. If NRR drops below 120%, that's a real warning sign for me.


What's Genuinely Impressive

Let me give credit where it's due, because there's a lot here that's excellent.

First non-GAAP profitable quarter in company history. Non-GAAP operating income of 10.1Mpositive.Non − GAAPEPSof+0.10 vs. expected -$0.17 — a beat of $0.27! That is a preposterous improvement. Compare to Q3 FY25 operating margin of -52.8% vs. Q3 FY26 at -21.6% on a GAAP basis. Thirty-one percentage points of improvement in one year! That is the operating leverage story you want to see.

FCF generation is real. $76.9M in FCF in a single quarter — up 394% year-over-year. The TTM FCF is over $240M. And Q1-Q3 alone generated $212M in FCF, already above their full-year guidance of $194-202M. The company is being conservative on FCF guidance. Very much a green flag.

Cloud ARR at $1.175B, 53% growth, 87% of total. This is the quality metric. Cloud customers have better pricing, lower churn, longer contracts, and higher expansion. The migration from on-prem is essentially complete (on-prem ARR down to 13% of total from 50% two years ago). The business model transformation is done, and it's transforming beautifully.

Enterprise penetration deepening. $100K+ customers up 27% YoY to 2,638. $1M+ customers at 162 (up from 114 a year ago), with 23 added in Q3 alone (a record). These large enterprise relationships are valuable and sticky.

Beat the quarter solidly. Revenue of $350.2M vs. consensus of $325.6M — a 7.6% beat. That's a meaningful beat, not a token one.


The Beat vs. The Guide

Q3 was great. The Q4 guide is sobering. Revenue guided to $341-343M — that's actually below Q3's 350.2M.Sequentialdecline!Thecompanyexplainsthisasseasonalityandtherollingoffofmaterialrightsrevenue.TheARRguide(1.44-1.45B for full year, implying ~$96-110M of net new ARR in Q4) is strong.

I note the FCF guide of $194-202M for the full year while Q1-Q3 alone generated $212M. This either means Q4 FCF will be negative (unusual for a strong seasonality quarter) or they're being very conservative. In either case, the full-year FCF number is likely to exceed guidance.

The real question, and the one I'm watching: What is FY27 guidance going to look like? That gets answered March 12. If they guide to 30%+ normalized revenue growth with FCF of $300M+, the stock re-rates. If they guide to 25% growth, I'll move on.


New Products: Real or Hype?

Identity business: $20M in ARR after three quarters of GA. Customer count doubled in Q3. 40% of identity customers are net-new to Rubrik — meaning these are genuinely new logos, not just upsells. This is very encouraging as a data point. $20M is immaterial to a $1.35B ARR company today, but the trajectory matters. If this hits $100M in 2-3 years, it adds meaningful growth.

Rubrik Agent Cloud: Still in beta. Not generating revenue. Managing AI agent risk is a real problem enterprises will pay to solve — I buy that thesis. But I've seen too many pre-revenue "next big things" to get excited before there are paying customers at scale.

Both products are worth watching. Neither changes my near-term conviction.


Valuation

The stock is down ~50% from its IPO highs, now trading around $50. The math:

For a 35% grower with 80%+ gross margins and an accelerating FCF trajectory, this is not expensive. Compare to CrowdStrike at 15x revenue on 25% growth — Rubrik looks like a bargain on that basis.

But I don't use valuation as a reason to buy. I use growth and business quality as the reason to buy, and valuation as a confirmation that I'm not overpaying. The growth here is real but decelerating. The business quality is high. The valuation is reasonable-to-cheap. That puts it in "hold" territory, not "back up the truck" territory.


My Assessment vs. Atlas

Atlas gave this 3.5/5 conviction, which I think is about right. Atlas flagged the same concerns I have: NRR stagnation, SBC levels, Cohesity-Veritas threat, material rights cliff.

Where I'd differ from Atlas: I don't get excited about valuation comparisons. The growth rate matters far more to me than whether it's 9x vs. 15x EV/revenue. A company decelerating from 55% to 33% guided growth is not the same as a company decelerating to 33% from 35%. Context of deceleration matters. Here the deceleration partly reflects non-recurring revenue falling off, which is fine — but the ARR growth is also stable at 33-35%, not accelerating. For Saul's method, "stable" is not what I'm looking for.

The key thing Atlas and I agree on: March 12 Q4 earnings is the real decision point. FY27 guidance is what matters.


The Bottom Line

Rubrik is a high-quality cloud company in the early innings of a profitability inflection. The fundamentals are strong — 80% gross margins, $243M TTM FCF, 34% ARR growth, record enterprise customer additions. The valuation is reasonable.

But revenue growth is decelerating to the low-30s, NRR is stuck at 120% with no expansion for five consecutive quarters, and the Q4 sequential revenue guide was actually below Q3. None of these are catastrophic, but together they mean this is not the "accelerating, must-own" company that would get a large position in my portfolio.

I would hold a small position and watch the March 12 earnings closely. The questions I need answered:

  1. FY27 initial guidance — above 30% normalized growth?
  2. Q4 NRR — did it hold at 120% or slip?
  3. Identity ARR — how big is it now?
  4. FY27 FCF guidance — does it show the operating leverage I expect?

If March 12 delivers strong FY27 guidance with NRR holding, this becomes a much more interesting addition. Until then: small position, close watch.

Best, Saul
