Rubrik, Inc.
Rubrik is executing well, but at $112.20 and 14.18x sales, the stock already discounts a lot more than management's own 25%-26% FY27 ARR growth and limited AI revenue outlook.
Rubrik is not a broken story. It is an expensive one. The company is executing at a high level, with FY2026 revenue up 33.4% to $1.3B, a dramatic improvement in operating margin from -127.9% to -51.4%, and a clean run of eight straight EPS beats. Q4 looked genuinely strong, with record $115M in net new subscription ARR, 50% subscription revenue growth, and $70M of free cash flow. If the question were whether Rubrik is winning in cyber resilience, the answer is yes.
The issue at $112.20 is what is already in the stock. Shares are trading at 14.18x sales, or more than 2.2x the peer average of 6.2x, after a 55.14% move in three months and with the stock sitting just 0.4% below its high. That might be justified for a company still accelerating with clear AI monetization leverage. But management is guiding FY27 subscription ARR to $1.829B-$1.839B, which is 25%-26% growth, and explicitly said, "The assumption on AI, while we are very excited, is we have not assumed much when we talk about fiscal 2027." That is a good sign for conservatism, not a good sign for paying an aggressive multiple today.
The case now depends on three things going right at once. First, Rubrik must keep converting ARR growth into margin and cash flow faster than investors expect, with FY27 free cash flow already guided to $265M-$275M. Second, win rates and large-customer adds need to remain strong enough to defend premium growth, especially after 32 new $1M+ ARR customers in Q4. Third, adjacent products such as Identity and Agent Cloud have to become meaningful revenue contributors before growth naturally decelerates further from scale. Those things can happen. The problem is that the stock already behaves as if they will.
That leaves the skew unattractive. A good company can still be a bad stock when the entry price assumes too much. Unless Rubrik starts proving materially higher earnings power than the current guide, or the shares pull back enough to better reflect execution versus valuation, the better stance is to avoid chasing strength here.
Rubrik sustains north of 30% growth, AI products commercialize earlier than expected, and free cash flow beats the $265M-$275M guide enough to support the premium multiple.
Strong execution continues, but valuation compresses as ARR growth settles into the 25%-26% range and investors demand more proof of durable earnings power.
Growth slips toward the low end of FY27 guidance, AI monetization stays negligible, and the stock de-rates closer to software peers from 14.18x sales.
Quant call (SELL) diverges from analyst consensus (Strong Buy: 19 buy / 0 hold / 0 sell) — resolve explicitly.
Never, ever invest in the present.
Forward earnings power is improving fast, but the stock is no longer cheap enough to simply underwrite improvement. Rubrik has moved from deep losses toward positive non-GAAP EPS, yet investors are paying a hyper-growth multiple while management is guiding 25%-26% FY27 ARR growth and still assuming little AI revenue contribution. The moat looks better now than two years ago because cyber recovery, identity recovery, and cloud data security are broadening the platform, but over 3-5 years the key question is whether AI becomes a true monetization tailwind or just another feature competitors can match. Secularly, ransomware, cyber-resilience regulation, and rising recovery requirements help demand, but with the 10-year Treasury at 4.94%, the market is less forgiving of expensive software names unless earnings scale catches up quickly.
- Valuation is stretched at 14.18x sales, versus a 6.2x peer average, despite the engine's $70.99 target implying -36.7% downside.
- FY27 guidance decelerates, with subscription ARR growth of 25%-26% and Q1 revenue growth of 31%-32% reported, below the pace implied by the current stock setup.
- Price action is crowded, with shares up 55.14% in 3 months, 11.99% in 1 week, and trading 0.4% below the all-time and 52-week high of $112.66.
- Execution has been excellent, with eight straight EPS beats, including $0.20 vs $0.03908 on 2026-08-27 and $0.16 vs -$0.02977 on 2026-06-04.
- Growth remains real, with FY2026 revenue of $1.3B, up 33.4%, and Q4 callouts showing 50% YoY subscription revenue growth plus record $115M net new subscription ARR.
- Cash generation is inflecting sharply, with FY27 free cash flow guided to $265M-$275M versus $0.1B in FY2026 and $70M delivered in Q4.
- Competitive positioning is improving, with management stating win rates were "north of 90%" in Q4 against legacy data protection vendors and 32 new $1M+ ARR customers added in the quarter.
- Valuation leaves little margin for error, at 14.18x P/S against a 6.2x peer average, while the quant framework points to $70.99 fair value and the pure P/S method gives only $46.69.
- Profitability is still weak on GAAP terms, with FY2026 operating margin of -51.4% and net margin of -53.7%, even after major improvement from the prior year.
- Growth is decelerating from a richer base, as FY27 ARR is guided to 25%-26% growth and management explicitly said, "The assumption on AI, while we are very excited, is we have not assumed much when we talk about fiscal 2027."
- The setup is technically extended and ownership is crowded, with 43.8% held by the top three institutions, 27.0% insider ownership, and 9.67% short interest, increasing the odds of volatility near earnings.

| Short interest | 9.67% | Elevated, with 4.2 days-to-cover |
The biggest risk to a SELL is that Rubrik converts its 1.829B-1.839B FY27 subscription ARR guide into much stronger-than-expected earnings power and keeps posting outsized beats like the recent +411.8% and +637.5% EPS surprises.
The next key catalyst is December 3, 2026 earnings, where investors need to see whether Q1 FY27 revenue lands within $365M-$367M, whether free cash flow tracks toward $265M-$275M, and whether AI products start contributing sooner than management has assumed.
Ownership is concentrated enough to amplify moves. The top three institutions hold 43.8%, insiders hold 27.0%, and short interest is 15.2M shares, or 9.67% of float, with 4.2 days to cover. Options positioning is flagged as a positive gamma regime, which can dampen near-term volatility, but with the stock 59.3% above its 200-day average and near the high, the setup looks crowded rather than under-owned.
Revenue grew 33.4% YoY, with Q4 total revenue up 46% on strong ARR conversion and some remaining material-rights tailwind.
Management is guiding 25%-26% YoY growth after record $115M net new subscription ARR in Q4.
Q4 subscription revenue grew 50% YoY, still the main growth engine.
Identity surpassed 900 customers in Q4, and Okta Recovery saw notable early deal activity.
Geographic mix is not available in the supplied dataset, which limits precision on regional demand concentration.
Rubrik posted a blowout Q4 and guided to another year of strong ARR growth with rising cash flow.
Management has earned credibility on near-term execution. Back in the 2025 Q2 call, Rubrik guided FY25 revenue to $830M-$838M, subscription ARR to $1.026B-$1.032B, and free cash flow to -$67M to -$57M, while Q3 subscription ARR contribution margin was guided to -8% to -7%. Since then, the company has scaled to $1.3B FY2026 revenue, improved operating margin to -51.4% from -127.9%, turned FY2026 free cash flow positive at $0.1B, and now guides FY27 free cash flow to $265M-$275M with Q1 FY27 subscription ARR contribution margin at 10%-11%. The direction of travel has been consistent with what management promised, especially on sales efficiency and cash flow inflection, and the eight-quarter streak of EPS beats supports the view that this team tends to guide with room. The weaker point is that AI monetization has not yet become material, despite product progress such as Agent Cloud GA.
We ended the year that significantly exceeded our expectations. A spectacular Q4.
In Q1, we expect revenue of $365,000,000 to $367,000,000, up approximately 31% to 32%, or approximately 36% to 37% when normalized for material rights.
For the full year fiscal 2027, we expect subscription ARR in the range of $1,829,000,000 to $1,839,000,000, reflecting a year-over-year growth rate of approximately 25% to 26%.
The assumption on AI, while we are very excited, is we have not assumed much when we talk about fiscal 2027.
Our win rate against the data protection vendors across the board is, I will repeat, north of 90%. North of 90% in Q4.
Rubrik's moat rests on recovery-centric cyber resilience, not just backup. That matters because recovery workflows, policy controls, and integrations become embedded in customer operations, raising switching costs once workloads, identity, and incident-response playbooks are tied into the platform. Durability looks solid near term given management's stated "north of 90%" win rates against legacy vendors, but over a 3-5 year horizon the moat depends on whether Rubrik keeps extending into cloud, identity, and AI-driven threat response faster than larger security and infrastructure vendors can bundle adjacent features.
Capital allocation is still simple and mostly disciplined. Rubrik generated $0.1B of free cash flow in FY2026, guides to $265M-$275M in FY27, had $0.0B in buybacks, $0.0B in dividends, and $0.0B capex in the provided data, which is consistent with a software company still prioritizing operating scale over shareholder distributions. The main question is not whether management returns cash today, it is whether it can turn ARR growth into sustained cash generation while carrying $1.1B of debt.
Rubrik rates SELL at Medium conviction. The company is executing well enough to deserve investor interest, but not well enough to justify 14.18x sales with the stock pinned near its high while growth is guided to slow into the mid-20s on ARR. This is a valuation call, not a broken-business call. A materially lower entry price, or evidence that AI and adjacent products can push forward earnings power well beyond the current FY27 guide, would be the main reasons to revisit the rating. Until then, the downside to the $70.99 base case outweighs the upside from another beat.

Executive Summary
SELL, Medium conviction. Rated SELL, Medium conviction. Rubrik is a strong operating story, with FY2026 revenue up 33.4% to $1.3B, a clear margin improvement, and a string of large EPS beats, but the stock now sits 0.4% below its 52-week high and 59.3% above its 200-day average, leaving little room for any slowdown from the current premium valuation. The core issue is not business quality, it is that the market is pricing Rubrik more like a durable hyper-growth compounder than a company guiding to 31%-32% Q1 growth, 25%-26% FY27 ARR growth, and still reporting a -51.4% operating margin for FY2026.
Investment Thesis
Rubrik is not a broken story. It is an expensive one. The company is executing at a high level, with FY2026 revenue up 33.4% to $1.3B, a dramatic improvement in operating margin from -127.9% to -51.4%, and a clean run of eight straight EPS beats. Q4 looked genuinely strong, with record $115M in net new subscription ARR, 50% subscription revenue growth, and $70M of free cash flow. If the question were whether Rubrik is winning in cyber resilience, the answer is yes.
The issue at $112.20 is what is already in the stock. Shares are trading at 14.18x sales, or more than 2.2x the peer average of 6.2x, after a 55.14% move in three months and with the stock sitting just 0.4% below its high. That might be justified for a company still accelerating with clear AI monetization leverage. But management is guiding FY27 subscription ARR to $1.829B-$1.839B, which is 25%-26% growth, and explicitly said, "The assumption on AI, while we are very excited, is we have not assumed much when we talk about fiscal 2027." That is a good sign for conservatism, not a good sign for paying an aggressive multiple today.
The case now depends on three things going right at once. First, Rubrik must keep converting ARR growth into margin and cash flow faster than investors expect, with FY27 free cash flow already guided to $265M-$275M. Second, win rates and large-customer adds need to remain strong enough to defend premium growth, especially after 32 new $1M+ ARR customers in Q4. Third, adjacent products such as Identity and Agent Cloud have to become meaningful revenue contributors before growth naturally decelerates further from scale. Those things can happen. The problem is that the stock already behaves as if they will.
That leaves the skew unattractive. A good company can still be a bad stock when the entry price assumes too much.

Financial Strength
The balance sheet reads adequate, not pristine. A 1.64 current ratio supports near-term liquidity, and the business is clearly moving in the right direction on self-funding, with free cash flow turning positive at $0.1B in FY2026 and guided to $265M-$275M in FY27. That matters more than GAAP losses in the near term. Still, $1.1B of debt and a still-deep -51.4% operating margin mean Rubrik has not yet reached the kind of balance-sheet strength that justifies paying any price for growth.
Competitive Position
Rubrik's moat rests on recovery-centric cyber resilience, not just backup. That matters because recovery workflows, policy controls, and integrations become embedded in customer operations, raising switching costs once workloads, identity, and incident-response playbooks are tied into the platform. Durability looks solid near term given management's stated "north of 90%" win rates against legacy vendors, but over a 3-5 year horizon the moat depends on whether Rubrik keeps extending into cloud, identity, and AI-driven threat response faster than larger security and infrastructure vendors can bundle adjacent features.
Management & Guidance
Management's current guidance is strong and, based on the beat record, likely conservative around the edges. Q1 FY27 revenue is guided to $365M-$367M, or 31%-32% reported growth, with non-GAAP EPS of -$0.04 to -$0.02 and subscription ARR contribution margin of 10%-11%. FY27 revenue is guided to $1.597B-$1.607B, subscription ARR to $1.829B-$1.839B, and free cash flow to $265M-$275M. The credibility is high because management has consistently beat consensus and delivered the cash flow inflection it outlined over the last two years, but the guide also clearly signals moderation from the prior hyper-growth phase and minimal AI revenue near term.
Segment Analysis
- Total company revenue ($1.3B in FY2026): Revenue grew 33.4% YoY, with Q4 total revenue up 46% on strong ARR conversion and some remaining material-rights tailwind.
- Subscription ARR ($1.829B-$1.839B FY27 guide): Management is guiding 25%-26% YoY growth after record $115M net new subscription ARR in Q4.
- Subscription revenue (Not separately disclosed in provided data): Q4 subscription revenue grew 50% YoY, still the main growth engine.
- Identity (900+ customers): Identity surpassed 900 customers in Q4, and Okta Recovery saw notable early deal activity.
- Geography (Not disclosed in provided data): Geographic mix is not available in the supplied dataset, which limits precision on regional demand concentration.
Capital Allocation
Capital allocation is still simple and mostly disciplined. Rubrik generated $0.1B of free cash flow in FY2026, guides to $265M-$275M in FY27, had $0.0B in buybacks, $0.0B in dividends, and $0.0B capex in the provided data, which is consistent with a software company still prioritizing operating scale over shareholder distributions. The main question is not whether management returns cash today, it is whether it can turn ARR growth into sustained cash generation while carrying $1.1B of debt.
Management Execution & Track Record
Management has earned credibility on near-term execution. Back in the 2025 Q2 call, Rubrik guided FY25 revenue to $830M-$838M, subscription ARR to $1.026B-$1.032B, and free cash flow to -$67M to -$57M, while Q3 subscription ARR contribution margin was guided to -8% to -7%. Since then, the company has scaled to $1.3B FY2026 revenue, improved operating margin to -51.4% from -127.9%, turned FY2026 free cash flow positive at $0.1B, and now guides FY27 free cash flow to $265M-$275M with Q1 FY27 subscription ARR contribution margin at 10%-11%. The direction of travel has been consistent with what management promised, especially on sales efficiency and cash flow inflection, and the eight-quarter streak of EPS beats supports the view that this team tends to guide with room. The weaker point is that AI monetization has not yet become material, despite product progress such as Agent Cloud GA.
Positioning & Flows
Ownership is concentrated enough to amplify moves. The top three institutions hold 43.8%, insiders hold 27.0%, and short interest is 15.2M shares, or 9.67% of float, with 4.2 days to cover. Options positioning is flagged as a positive gamma regime, which can dampen near-term volatility, but with the stock 59.3% above its 200-day average and near the high, the setup looks crowded rather than under-owned.
Bull Case
- Execution has been excellent, with eight straight EPS beats, including $0.20 vs $0.03908 on 2026-08-27 and $0.16 vs -$0.02977 on 2026-06-04.
- Growth remains real, with FY2026 revenue of $1.3B, up 33.4%, and Q4 callouts showing 50% YoY subscription revenue growth plus record $115M net new subscription ARR.
- Cash generation is inflecting sharply, with FY27 free cash flow guided to $265M-$275M versus $0.1B in FY2026 and $70M delivered in Q4.
- Competitive positioning is improving, with management stating win rates were "north of 90%" in Q4 against legacy data protection vendors and 32 new $1M+ ARR customers added in the quarter.
Bear Case
- Valuation leaves little margin for error, at 14.18x P/S against a 6.2x peer average, while the quant framework points to $70.99 fair value and the pure P/S method gives only $46.69.
- Profitability is still weak on GAAP terms, with FY2026 operating margin of -51.4% and net margin of -53.7%, even after major improvement from the prior year.
- Growth is decelerating from a richer base, as FY27 ARR is guided to 25%-26% growth and management explicitly said, "The assumption on AI, while we are very excited, is we have not assumed much when we talk about fiscal 2027."
- The setup is technically extended and ownership is crowded, with 43.8% held by the top three institutions, 27.0% insider ownership, and 9.67% short interest, increasing the odds of volatility near earnings.
Valuation & Price Target
Engine price target $70.99 (-36.7% vs current), Low confidence.
- P/S Multiple: $46.69 (45% weight)
- Quality-adjusted: $125.66 (20% weight)
The rating aligns with the quant baseline SELL, but with Medium rather than low conviction because the business is executing materially better than a simple screen might imply. The reason not to upgrade despite that execution is valuation: 14.18x sales versus 6.2x peers, a stock price at $112.20 that is almost exactly at the all-time high, and management's own FY27 outlook for 25%-26% ARR growth plus limited AI contribution. The quality-adjusted method reaches $125.66, which explains why the call is not High-conviction SELL, but the blended target of $70.99 better reflects the tension between strong fundamentals and an already crowded stock. Sell-side consensus is uniformly bullish, 19 buy / 0 hold / 0 sell, but that is low-signal here and does not offset the valuation gap.
Risk Assessment
Risk score 52/100 (Moderate). The biggest risk to a SELL is that Rubrik converts its 1.829B-1.839B FY27 subscription ARR guide into much stronger-than-expected earnings power and keeps posting outsized beats like the recent +411.8% and +637.5% EPS surprises.
The Bottom Line
Rubrik rates SELL at Medium conviction. The company is executing well enough to deserve investor interest, but not well enough to justify 14.18x sales with the stock pinned near its high while growth is guided to slow into the mid-20s on ARR. This is a valuation call, not a broken-business call. A materially lower entry price, or evidence that AI and adjacent products can push forward earnings power well beyond the current FY27 guide, would be the main reasons to revisit the rating. Until then, the downside to the $70.99 base case outweighs the upside from another beat.
