December 4, 2025 – New York / Palo Alto
Rubrik Inc. (NYSE: RBRK) just delivered the kind of quarter that can change a growth stock’s story almost overnight. The cybersecurity and “Security & AI Operations” company smashed Wall Street expectations for its fiscal third quarter 2026, posting a surprise profit, accelerating revenue growth and sharply narrowing its loss outlook for the year. Investors responded in a hurry: Rubrik shares jumped roughly 10–13% in after‑hours trading after the results and new guidance hit the tape. [1]
At the same time, the earnings release effectively “answers” a big open question raised in pre‑earnings analysis from Zacks/Nasdaq, Seeking Alpha and Finimize: could Rubrik justify its premium valuation by proving a credible path to profitability while sustaining hyper‑growth? [2]
So, after this blow‑out quarter, should investors buy, sell or hold Rubrik stock? Let’s break down the numbers, the new guidance, the strategic backdrop and how the Street is reacting.
Q3 2026: Rubrik’s Earnings Beat by the Numbers
Rubrik’s fiscal Q3 2026 (ended October 31, 2025) was its strongest as a public company on almost every key metric. According to the company’s official earnings release: [3]
Growth and scale
- Total revenue: $350.2 million, up 48% year over year from $236.2 million.
- Subscription revenue: $336.4 million, up 52% versus a year ago, underscoring the shift to a recurring SaaS model.
- Subscription ARR (Annual Recurring Revenue): $1.35 billion, growing 34% year over year.
- Large customers: 2,638 customers with $100,000+ in subscription ARR, up 27% year over year. [4]
Profitability & margins
- GAAP gross margin: 80.5%, up from 76.2% a year earlier.
- Non‑GAAP gross margin: 82.8%, versus 79.2% in the prior‑year quarter.
- Subscription ARR contribution margin: 10.3%, a big swing from ‑3.3% a year ago, showing rising operating leverage in the subscription base. [5]
Earnings & cash flow
- GAAP net loss per share: –$0.32, improved from –$0.71 a year ago.
- Non‑GAAP EPS (diluted):+$0.10, versus a non‑GAAP loss of –$0.21 last year – Rubrik’s first positive non‑GAAP profit quarter. [6]
- Cash flow from operations: $85.5 million (vs $23.1 million a year ago).
- Free cash flow: $76.9 million, up from $15.6 million in the prior‑year quarter – nearly a 5x increase. [7]
- Liquidity: $1.60 billion in cash, cash equivalents and short‑term investments as of October 31, 2025. [8]
Rubrik still posts a GAAP net loss – about $63.8 million for the quarter – but the dramatic improvement in non‑GAAP profitability and free cash flow is exactly what growth investors wanted to see. [9]
From Expected Loss to Surprise Profit
Heading into the print, Zacks (via a Nasdaq article) was calling for: [10]
- Revenue of about $320.9 million, up ~36% year over year.
- A non‑GAAP loss of $0.17 per share, slightly worse than estimates a month earlier.
Management itself had guided to Q3 revenue of $319–321 million and a non‑GAAP subscription ARR contribution margin of roughly 6.5%, with losses still expected. [11]
Instead, Rubrik delivered:
- Revenue that beat guidance and consensus by nearly $30 million, coming in at $350.2 million. [12]
- Non‑GAAP EPS of +$0.10, a swing of roughly $0.27 per share versus expectations of a $0.17 loss. [13]
Finimize framed the quarter as a showcase of what happens when a fast‑growing software company keeps revenue growth near 50% while simultaneously clamping down on costs, turning last year’s non‑GAAP loss into a modest profit. [14]
At the same time, QuiverQuant and the company’s own financial statements remind investors that Rubrik is still GAAP‑unprofitable: operating and net losses persist, and total liabilities – including convertible notes – have risen. [15]
In other words, Rubrik has proved its unit economics and cash‑flow engine are working – but the GAAP income statement still reflects heavy investment and substantial stock‑based compensation.
Stock Reaction: Why Rubrik Shares Are “Rocketing”
Shortly after the results, multiple outlets reported a sharp move higher in Rubrik’s share price:
- Finimize noted the stock was up more than 10% after hours following the beat and guidance raise. [16]
- GuruFocus cited a 12% post‑market gain, while adding that subscription revenue grew 52% and free cash flow “dramatically” improved. [17]
- Benzinga reported an after‑hours move of roughly 10.1% to around $77.60, highlighting the top‑ and bottom‑line beat and the guidance upgrade. [18]
- Other coverage, including 24/7 Wall St. and Red94, described double‑digit percentage gains of about 13% after the “crushing” Q3 print. [19]
- Seeking Alpha’s news desk summed it up with the headline: “Rubrik rockets on Q3 financial results as revenue surges 48%.” [20]
The catalyst is clear: investors are rewarding the combination of rapid growth, first‑time non‑GAAP profitability and clearer visibility on the path to sustained free‑cash‑flow generation.
Guidance: Rubrik’s 2026 Outlook Gets a Major Upgrade
Perhaps the most important part of the release for long‑term shareholders is the new guidance. Rubrik didn’t just beat in Q3 – it raised its targets for Q4 and full‑year fiscal 2026. [21]
Q4 FY 2026 outlook
For the current quarter (Q4 FY 2026), Rubrik now expects:
- Revenue: $341–343 million.
- Non‑GAAP subscription ARR contribution margin: ~9%.
- Non‑GAAP net loss per share: –$0.12 to –$0.10.
These revenue targets are above prior Street estimates around $325 million, and the EPS range is materially better than earlier expectations. [22]
Full‑year FY 2026 outlook
For the full fiscal year 2026, Rubrik now guides to: [23]
- Subscription ARR: $1.439–1.443 billion.
- Revenue: $1.280–1.282 billion.
- Non‑GAAP net loss per share:–$0.20 to –$0.16.
- Non‑GAAP subscription ARR contribution margin: ~9%.
- Free cash flow: $194–202 million.
Crucially, Finimize notes that Rubrik slashed its projected non‑GAAP loss per share for the year from a previous range around –$0.50 to –$0.44 to the current –$0.20 to –$0.16, while nudging revenue guidance above both prior company targets and analyst consensus (roughly $1.23 billion). [24]
This combination – higher growth, smaller losses and rising free cash flow – is exactly the profile that public markets increasingly demand from high‑growth software names.
Strategic Context: Cyber Resilience + AI Tailwinds
On top of the numbers, Rubrik is leaning hard into two powerful themes: cyber resilience and enterprise AI.
Recent press releases and partner announcements highlight a string of AI‑centric launches and collaborations:
- Rubrik Agent Cloud for Amazon Bedrock AgentCore – unveiled at AWS re:Invent 2025 – automatically discovers AI agents built on Amazon Bedrock, monitors their behavior, enforces guardrails and can roll back harmful agent actions across multi‑cloud environments. [25]
- A multi‑year strategic collaboration agreement (SCA) with AWS aims to help customers build proactive cyber resilience while safely scaling AI workloads on AWS, unifying backup, threat analysis and recovery. [26]
- New offerings such as Intelligent Business Recovery for Microsoft 365 and DevOps Protection for Azure DevOps and GitHub are designed to orchestrate recovery after cyberattacks or major outages in Microsoft‑centric environments. [27]
- Rubrik also launched Okta Recovery, expanded its integration with CrowdStrike for identity resilience and announced a Business Resilience‑as‑a‑Service partnership with Cognizant – all highlighted in the Q3 release. [28]
In the Q3 press release, management stressed record net new subscription ARR and free cash flow, and pointed to rising demand from organizations wanting to be both “secure and AI‑ready” as generative AI and agentic systems spread across enterprises. [29]
Industry recognition backs up that story: Rubrik was named a leader in the IDC MarketScape: Worldwide Cyber‑Recovery 2025 Vendor Assessment, reinforcing its positioning at the high end of the data‑recovery and cyber‑resilience market. [30]
How Wall Street Viewed Rubrik Before This Quarter
Pre‑earnings, the Street was already broadly positive on Rubrik – but cautious about valuation and volatility.
- Zacks / Nasdaq rated the stock a “Hold” (Rank #3) going into Q3, noting that its forward 12‑month price‑to‑sales multiple of about 9.1x looked stretched versus an industry average near 4.9x. [31]
- The same piece highlighted that Rubrik shares had fallen about 30% over the prior six months, underperforming the broader tech sector despite strong fundamentals. [32]
- A November Seeking Alpha deep‑dive titled “Rubrik: Dominating Cloud Data Resilience – Still an Undervalued Growth Play” argued that Rubrik’s 51% revenue growth in FQ2 2026, 57% cloud ARR growth and sticky customer base justified a Buy rating and an $86 price target, even at a premium valuation. [33]
- Cantor Fitzgerald, ahead of today’s release, trimmed its price target to $105 from $115 but kept an Overweight stance, calling Rubrik an attractive entry point after a pullback and noting consensus targets clustered roughly between $90 and $130. [34]
Another Yahoo Finance / Insider Monkey article this week framed Rubrik as one of Wall Street’s “best up‑and‑coming tech stocks to buy”, citing strong institutional interest and bullish analyst sentiment. [35]
In short, the Street already liked the story – robust growth, strategic AI and cloud partnerships, and a clear niche in cyber resilience – but needed proof that Rubrik could tighten its loss profile and grow into its valuation. Today’s Q3 results directly address that concern.
Valuation After the Spike: Still Pricey, or Justified?
Even after the after‑hours jump, Rubrik remains a high‑multiple growth stock:
- Zacks data pegged Rubrik’s forward P/S around 9x heading into earnings. [36]
- GuruFocus shows a price‑to‑sales ratio in the low‑teens (around 12x on its methodology), with a gross margin near 78% and a trailing three‑year revenue growth rate of about 26%. [37]
- Its market capitalization sits near the mid‑teens billions of dollars, while net margins remain deeply negative on a GAAP basis (around –41% on a trailing basis), and the balance sheet includes sizable convertible debt and a negative equity position. [38]
At the same time, analyst reports and aggregator data indicate: [39]
- Consensus price targets roughly in the US$90–130 range, with several major firms (Cantor, Guggenheim, KeyBanc, FBN) reiterating Buy / Overweight‑type ratings in recent months.
- Targets that imply meaningful upside from levels before the Q3 move, assuming Rubrik can sustain >30–35% annual revenue growth and progressively expand margins.
So is it expensive? Yes – by traditional metrics. But for many growth‑oriented investors, Rubrik is increasingly being judged as a “rule of 40+” style SaaS name, where the mix of high growth, high gross margins and improving free cash flow can justify double‑digit sales multiples.
Risks: What Could Go Wrong From Here?
Even after such a strong quarter, Rubrik is not a low‑risk story. Key risks highlighted by the company and independent analyses include: [40]
- Continued GAAP losses and leverage
- GAAP net losses and negative equity persist, and Rubrik carries significant convertible notes. If growth slows or margins stall, leverage could become more uncomfortable.
- Execution in a brutally competitive market
- Rubrik competes with heavyweight security and data‑protection vendors (including Fortinet and others highlighted in the Zacks/Nasdaq piece), many of which are also embedding AI into their platforms. Losing sales momentum or facing pricing pressure could hit growth and margins. [41]
- Valuation risk and volatility
- With P/S in the high single to low double digits, Rubrik’s stock is inherently sensitive to sentiment shifts in growth software and macro conditions (rates, risk appetite). GuruFocus notes high share‑price volatility and a middling Altman Z‑Score, which flags financial‑stress risk if conditions deteriorate. [42]
- Cyber and AI‑related operational risks
- As a security vendor and AI‑infrastructure partner, Rubrik faces high stakes: outages, breaches, or failures in its data‑protection or AI‑governance offerings could damage reputation and growth prospects.
- Heavy stock‑based compensation
- Rubrik’s non‑GAAP profitability depends in part on backing out sizable stock‑based comp. While common in SaaS, this can dilute shareholders over time.
Buy, Sell or Hold Rubrik Stock After Q3?
Nothing here is personalized investment advice, but the current setup can be framed in terms of three broad investor profiles:
1. Growth‑oriented investors
For investors who prioritize growth, market position and free‑cash‑flow trajectory over near‑term GAAP profitability, Rubrik’s Q3 report is likely a strong positive:
- Revenue growth accelerated to 48%.
- Non‑GAAP results flipped to a profit a year ahead of what many expected.
- Free cash flow is scaling sharply, with management now targeting roughly $200 million for FY 2026. [43]
Add in tailwinds from AI, cloud security and deepening ties with AWS and Microsoft, and it’s clear why many analysts keep Rubrik on their buy lists despite premium valuation. [44]
2. Value‑sensitive or risk‑averse investors
If your focus is valuation and downside protection, Rubrik still looks demanding:
- Multiples are well above sector averages. [45]
- GAAP profits remain negative, and the balance sheet carries notable leverage. [46]
Pre‑earnings, Zacks rated the stock a Hold, essentially telling investors to wait for a better entry point. [47] After today’s spike, that “wait for a pullback” stance may still resonate with more conservative investors.
3. Existing shareholders: hold, trim or add?
For those already holding Rubrik:
- The Q3 report and guidance de‑risk the story, proving management can beat and raise while moving toward profitability.
- However, the stock’s sharp post‑earnings pop and ongoing volatility argue for re‑checking position size relative to risk tolerance.
Some holders may see this as validation to hold or even add on future dips, while others could view the rally as a chance to lock in part of the gains and rebalance.
What to Watch Next
Looking beyond today, key catalysts and checkpoints include: [48]
- Q4 FY 2026 results – whether Rubrik can maintain ~40%+ growth and approach breakeven on a full‑year non‑GAAP basis.
- Adoption of Rubrik Agent Cloud and AI‑related offerings, especially on AWS Bedrock and Microsoft Copilot Studio.
- Customer metrics – continued growth in $100K‑plus ARR customers and maintaining >120% dollar‑based net retention.
- Analyst reactions – potential price‑target hikes or rating changes as firms digest the Q3 beat and new guidance.
- Upcoming investor events, including Rubrik’s presentation at the Barclays Global Technology Conference on December 10, 2025, which could provide more color on strategy, AI and long‑term margins. [49]
Bottom Line
Rubrik’s Q3 2026 report is a major inflection point:
- It validates the company’s high‑growth, high‑margin, subscription‑heavy model.
- It establishes a real‑world track record of beating expectations while tightening losses and scaling free cash flow.
- It deepens the strategic narrative around cyber resilience and AI governance, thanks to new deals with AWS and Microsoft.
The stock is still not cheap, and meaningful execution and macro risks remain. But for investors looking for a pure‑play bet on data security plus AI‑driven infrastructure, with accelerating fundamentals, Rubrik’s latest earnings and guidance push it firmly into the conversation as one of the market’s more compelling – if volatile – growth names.
