Date: 2026-03-13 Quarter: Q4 FY26 (ended Jan 31, 2026) Analyst: wsm007 Position: Long RBRK 7.2% + LEAPS Jan'27 $85C 4.4%
I listened to the call and found very little to complain about. Record quarter on every dimension that matters. Net new ARR of 115Mcrushedmybullcase(96M). Revenue beat by 10.4%. FCF of $238M vs $202M guide. Second consecutive non-GAAP profitable quarter. Three S-curves stacking: (1) backup/resilience, (2) identity — ramping faster than S-curve #1 did at the same stage per the CEO, and now (3) controlling and recovering from agents (nascent). Record ARR added, record beat, record initial guide for next year, record large ARR customers added. Lots of momentum, relative competitive advantage, and no sign of any company-specific headwinds. The stock yawned — I attribute that entirely to the continuing "AI eating software" macro angst, which the CEO addressed head-on: they're a system of record of last resort, sees no reason at all to worry. The guide is sandbagged and the net new ARR acceleration is the single most important signal. Thesis: Strengthening.

Q4 FY26 QoQ of +7.8% vs prior Q4s: FY25 +9.3%, FY24 +5.7%, FY23 -1.5%. Solid. Better than two of three prior Q4s. My Q3 review worried about a -2.3% sequential decline (based on old prelim). That fear was completely wrong — actual Q4 beat the 341 − 343Mguideby * *35M (10.4%)**.
**Q1 FY27 guide of 365 − 367Mimplies − 3.4408M — 11% above guide midpoint. This is the sandbagging signal. I expect Q1 to come in at $385-395M.
The grids tell the story. Sub ARR initial guide growth re-accelerated from 24.0% to 25.5%. Implied net new ARR in the guide went from $262M to 372M(+4270M → $163M). FY27 net new ARR guided flat at $372M after they just doubled it in FY26 — classic sandbag. This is not a company losing confidence. This is a company setting a bar they know they'll clear by a wide margin.
| Metric | FY25 | FY26 | Growth | FY27 Guide | Growth |
|---|---|---|---|---|---|
| Total Revenue | $887M | $1,316M | +48% | $1,602M | +22% reported |
| Sub Revenue | $829M | $1,264M | +53% | — | — |
| Material Rights | ~$0 | ~$68M | — | declining | headwind |
| Normalized Revenue | $887M | ~$1,248M | +41% | $1,602M | +28% |
Material rights (~$68M in FY26, declining in FY27) create a 6pp optical headwind. The street sees "48% → 22% reported growth" and panics. Normalized reality: 41% → 28%. Still a deceleration, but nothing like the headline suggests.
→ The market is pricing the deceleration headline, not the normalized reality. That's the opportunity.
This is the real story. Net new ARR is the forward-looking bookings signal. It's accelerating sharply:
| Quarter | Net New ARR ($M) | QoQ | YoY | Seasonality |
|---|---|---|---|---|
| Q1 FY25 | 72 | — | — | Spring |
| Q2 FY25 | 63 | -12.5% | — | Summer trough |
| Q3 FY25 | 83 | +31.7% | — | Fall build |
| Q4 FY25 | 91 | +9.6% | — | Year-end flush |
| Q1 FY26 | 88 | -3.3% | +22% | Spring (expected dip) |
| Q2 FY26 | 71 | -19.3% | +13% | Summer trough |
| Q3 FY26 | 95 | +33.8% | +14% | Fall build |
| Q4 FY26 | 115 | +21.1% | +26% | Record |
$115M is a full $19M above my bull case of $96M. FY26 total net new ARR: $369M — exactly double FY25's $185M. Management guided FY27 to $372M implied net new ARR (ARR guide $1,834M - current $1,462M). That's basically flat YoY — the classic sandbag.
**Cloud ARR: 1, 290M(88172M). The migration is effectively complete. What remains is pure cloud-native new business.
$1M+ Customer Net Adds: 32 — another record. >50% YoY growth. This is the enterprise penetration signal. Large customers = multi-year, multi-product, sticky. Combined with $100K+ customers at 2,805 (+25% YoY, representing 87% of ARR), the revenue quality is high.
→ Leading indicators diverging bullishly from reported ARR growth (34% YoY) and guided growth (25-26%). Net new ARR at $115M record + 32 $1M+ customers = the bookings engine is running hotter than at any point in company history.
This is the most important framing for RBRK right now. The company has three distinct S-curves, each at a different maturity:
S-Curve 1: Backup/Resilience (mature, scaling). The core business. $1.46B ARR, 90%+ win rate vs legacy, still early in the legacy replacement cycle. This is the cash engine.
S-Curve 2: Identity (ramping — faster than S-curve 1 at the same stage). CEO explicitly said identity is ramping faster than the backup/resilience product did at the equivalent stage. Fastest-growing product in the portfolio, exceeded internal expectations. This is the next revenue pillar.
S-Curve 3: Agent Control & Recovery (nascent). Rubrik Agent Cloud — controlling, monitoring, and recovering from agentic AI operations. GA announced, integrating with Amazon Bedrock AgentCore and Microsoft Copilot Studio. Very early days but the TAM could be enormous as enterprise agent deployment scales.
The power of stacking S-curves: Each curve provides growth as the prior one matures. S-curve 1 generates cash. S-curve 2 is already contributing to net new ARR. S-curve 3 extends the growth runway into FY28+. This is why the 27-28% FY27 guide understates the trajectory — it's mostly S-curve 1, with S-curve 2 just beginning to contribute meaningfully.
Six consecutive quarters at ">120%". No precision, no improvement. But in the context of three stacking S-curves, $115M record net new ARR, and accelerating large customer adds, NRR is a secondary metric right now.
NRR will re-accelerate when identity hits sufficient scale ($50M+ ARR) to move the blended number. At <2% of ARR today, identity is immaterial to NRR math. The re-acceleration case is FY28.
If NRR cracks below 120%, that changes the picture. But I'm not losing sleep over a flat NRR when every other leading indicator is at a record.

| $1M+ Total (est.) | 162 | — | — | ~226 | ~258 | >50% YoY |
$1M+ total counts were disclosed only at Q4 FY25 (162) and the Q3 FY26 transcript noted ">50% growth in our $1M subscription base." Q1-Q2 FY26 net adds not disclosed — RBRK only began reporting this metric at Q3 FY26.
The $100K+ net adds tell the enterprise story: Q4 FY26 added 167 — a record. The seasonal pattern holds (Q4 > Q1 > Q2 < Q3 < Q4), but the magnitude is increasing. Q4 FY25 was also 161 — back-to-back Q4 records. And 87% of ARR now comes from these large customers. Combined with 32 $1M+ net adds (also a record), the enterprise penetration engine is running at full speed.
Non-GAAP GM at 83.7% is best-in-class for a data protection company. Pure software economics. The progression from 79.7% → 83.7% in five quarters (+400bps) with non-GAAP GP growing from $205.8M to $316.0M (+54% YoY) shows cloud mix at 88%+ driving scale. Further room toward 85%+.
Non-GAAP operating income trajectory is the inflection story: -29.0M → −18.2M → -4.4M → +10.1M → +$6.1M. The progression from deep loss to profit in four quarters is textbook operating leverage. Q4 stepped back from Q3's $10.1M peak due to seasonally higher S&M spend, but full-year FY26 non-GAAP op loss was only -$6.4M — essentially breakeven. FY27 guide implies full-year non-GAAP profitability (0.07−0.27 EPS on 232M shares = ~$16-63M net income). This is the inflection the market needs to see.
FCF: $70.1M Q4, $237.8M FY26 vs $202M guide. Overdelivered by $36M (18%). FY27 FCF guide of $265-275M (midpoint 270M)isconservativegivenFY26outperformance.IexpectFY27FCFof * *310-330M**. At $320M, this trades at ~36x FCF — reasonable for a 28% grower.
SBC declining rapidly as % of revenue: 33% → 22.5% in four quarters. FY26 total SBC was $329M vs $914M FY25 (IPO effects). On $1.32B revenue, that's 25.0%. Must continue trending toward <20% in FY27. Shares outstanding: 201M, up from 188M (+6.8% dilution). Elevated but declining rate.

Summary: The quarter was spectacular. The FY27 initial guide is a record — $1.6B revenue, $1.83B ARR, $270M FCF — and it's sandbagged. The market got a blowout Q4 and the strongest initial guide Rubrik has ever issued, yet the stock yawned. Classic "AI eating software" macro angst overriding company-specific execution. The Q4 to FY27 guide gap is the opportunity.

Peer comparison (Jamin Ball territory):
| Company | EV/Rev | Growth | PEG-equiv |
|---|---|---|---|
| CRWD | ~15x | ~25% | ~0.60x |
| RBRK | 7.3x | 28% norm. | 0.26x |
| Discount | 53% | RBRK growing faster | — |
RBRK is trading at half the multiple of CRWD despite growing faster. The discount reflects: (1) profitability immaturity (closing rapidly), (2) post-IPO overhang, (3) NRR flatline, (4) material rights noise. Three of these four are resolving. Only NRR remains a genuine concern.
Analyst consensus: $107 target (19 analysts, Buy). That's 86% upside. The street sees the value; the stock price hasn't caught up.
Stock at ~$57.50, strike at $85, ~10 months to expiry. Need +48% move.
Path to $85:
The LEAPS work if: (a) FY27 beats are sustained through the year (high probability given sandbagged guide), AND (b) the market re-rates from 7.5x to 9x+ EV/ARR (requires profitability proof points through the year). Both conditions are plausible but not certain.
Decision: Hold the LEAPS. The $115M net new ARR and profitability inflection materially de-risked the fundamental case. What's left is multiple expansion risk — which is a market sentiment call, not a business quality call. I'm comfortable with that asymmetry.
Bipul Sinha (CEO): "The acceleration in net new subscription ARR growth in Q4 at our scale demonstrates that Rubrik is an increasingly critical platform for the AI era." — This is the framing I want to hear. Not "solid" or "steady" — acceleration at scale.
On legacy displacement: "Our win rate against the data protection vendors across the board is, I will repeat, north of 90%. North of 90% in Q4. The only deal that we are losing is the fight that we are not in." — Competitive moat confirmed. The question isn't whether Rubrik wins deals — it's whether they can get into enough fights.
On AI disruption risk (Mizuho question): "Rubrik is a very large and complex piece of software... it is not something that you can wipe code on, an LLM can solve. And we are the system of record of last resort around data and identity." — Good answer. Enterprise-grade data protection isn't an LLM problem. It's a 12-year platform engineering problem.
On Agent Cloud: "Everybody with a mother is jumping into this market... traditional cybersecurity companies will not be suitable for this market because traditional cybersecurity is all about rule-based platforms." — Honest about competition. Differentiation claim is real-time dynamic guardrails vs rule-based approaches.
On CRO transition: "We hired Jesse almost three years ago with this in mind... he has been a CRO in training for the last almost three years." — Planned succession, not panic. Reduces execution risk.
Kiran Choudary (CFO) on Q4 pull-forward: "I am very pleased with the 20% growth [in net new ARR]. And I will not call out anything from Q4 impacting Q1." — Explicitly denied pull-forward. CFO guiding to look at net new ARR on annual basis.

Rubrik delivered the best quarter in company history by every meaningful metric. Revenue +46% YoY with a 10.4% beat. Net new ARR $115M — record, 22% above my bull case. FCF $238M for the year. Non-GAAP profitability achieved. GAAP GM expanding to 81.5%. Win rate >90%. Record large customer adds (32 $1M+). Record initial FY27 guide. No company-specific headwinds anywhere.
The structural story is three S-curves stacking: backup/resilience (cash engine, still early in legacy replacement), identity (ramping faster than S-curve 1 at the same stage), and agent control/recovery (nascent, enormous TAM). This is why the 27-28% FY27 guide understates the trajectory — it's sandbagged, and the bookings engine ($115M record net new ARR) confirms it. I expect FY27 to print closer to 30-32% normalized.
NRR is flat at ">120%" for six quarters. In the context of everything else firing on all cylinders, this is secondary — a math problem (identity <2% of ARR) that resolves as S-curve 2 scales. If it cracks below 120%, I reassess.
The market doesn't get it because of macro "AI eating software" angst. The CEO addressed this directly: Rubrik is a system of record of last resort, 12 years of enterprise-hardened platform engineering — not something an LLM replaces.
Thesis: STRENGTHENING (upgraded from Intact). Three stacking S-curves + accelerating net new ARR at record scale + profitability inflection + 90%+ win rates + no headwinds. The valuation at 7.3x EV/run-rate revenue for a 28% grower with 84% GM and $270M+ FCF is cheap. CRWD trades at twice the multiple for lower growth.
Action: Hold equity position (7.2%). Hold LEAPS ($85C Jan'27, 4.4%) — path alive but tight; reassess after Q1 FY27.
The only thing that makes me sell: NRR below 120%, or two consecutive quarters of net new ARR <$80M.
