AI analysis

TickerTalks’ read on the fundamentals and what’s driving the move.

Proven numbersCooling offAI verdict · as of 2026-08-30

Catching its breath after a run — could pick back up or fade from here.

Down 13% today on a strong Q2 print — cyber-resilience name growing 38% got punished for a guide the market wanted stronger.

Rubrik is the leader in cyber-resilience and data-security software — think of it as backup + air-gapped recovery in the age of ransomware, with an increasing overlay of AI-driven threat detection. It posted a strong Q2 and the tape still took 13% off, which is the setup worth unpacking.

How to read the pullback:

  • Q2 was genuinely strong: revenue grew 38% year-on-year to $427M, subscription ARR grew 33% to $1.66B, cloud ARR grew 39% to $1.48B — the metrics that move a cyber-software stock, all beat.
  • The guide got the market angry: management's outlook underwhelmed against elevated expectations after CRWD-style rerates; Piper Sandler ($114) and DA Davidson / Barclays ($115) reiterated buys — analysts see the print, traders punished the guide.
  • Valuation still at cyber-software peaks: 10.5x sales for a business with -21% operating margin and a soft guide is the tension — mechanics strong but less cushion than the price targets suggest.
  • Insider activity is busy: Choudary sold $983K after exercising, plus a fresh Form 3 from new director Russak-Aminoach — board being augmented, individual insiders still trimming into strength.
  • Volume 3.1x baseline on today's move signals real institutional repositioning, not a shakeout.

The December 3 print is the resolution — ARR reacceleration and margin walk validates the 38% growth story and gets the multiple back; another guide-below-street with soft cloud-ARR momentum unwinds the recent rally and pushes shares back below $80.

What to watch: December 3 earnings — ARR reacceleration (needs to hold above 33% for subscription ARR), cloud ARR momentum, and any margin walk toward positive; another soft guide unwinds the recent rally and pushes shares back below $80.

X sentiment

What the X crowd is saying right now — descriptive, summarised from the day’s posts.

Mixed sentiment64 posts analyzed · as of 2026-08-30

Rubrik posters are split between the fundamentals and the tape. The print itself was strong, with revenue of $427.3M versus $396M expected, EPS of $0.20 versus $0.04, subscription ARR of $1.66B up 33% year-over-year and FCF margin at 15%, and analysts including Piper Sandler, Barclays and Rosenblatt raising targets to about $114-$120. Yet the stock still dropped roughly 10% after hours, and posters attribute it to elevated expectations, a lofty guide-through and profile-taking. The framing is: great quarter, mediocre reaction.

Industry overviewAI analysisGenerated by AI from underlying data

Where Software - Infrastructure sits in its cycle right now — and what that implies for $RBRK.

Software - Infrastructure · Technology

SaaS multiples remain compressed as rate-sensitive valuations weigh on pure-play software; customers are lengthening deal cycles outside of AI-native workloads. AI co-pilot upsell is the only clear near-term catalyst — companies without it are treading water.

What this means for $RBRK

Partial — cloud infrastructure exposure benefits indirectly from hyperscaler capex; core business is Rubrik, Inc.

Profitability, valuation, and the next earnings event — at a glance, with rule-of-thumb signals.

Key ratios

P/E
-51.8How much investors are paying per dollar of profit the company actually earned in the last 12 months. Lower means the stock looks cheaper relative to earnings.~15–25 is typical for the S&P 500; high-growth names trade 30+; hyper-growth or speculative can be 100+ or negative.
ROIC
-20.5%What percentage return the business earns on every dollar of capital (equity + debt) deployed in operations. The cleanest measure of business quality.Above ~15% is high-quality; consistently above 25% suggests a real moat. Below the company's cost of capital is value-destroying.
Op margin
-21.4%Operating profit (after sales, marketing, R&D, and overhead but before interest and taxes) as a percentage of revenue. The clearest view of how well the underlying business is run.Mature business above 20% is healthy; software businesses can run 30%+; commodity / retail businesses operate in single digits.
FCF yield
2.0%Free cash flow (operating cash flow minus capex) divided by the company's market cap. The cash-on-cash return you'd get owning the whole business at today's price.Above ~5% is attractive; below ~2% means you're paying up for growth. Capital-light businesses (software) run higher than capital-heavy ones (utilities).
P/S
10.5Same idea as P/E but per dollar of revenue. Useful for companies that aren't profitable yet, where P/E is meaningless.Under ~2 is cheap; software / SaaS often runs 8–15; well above 20 implies the market is pricing in very high future growth.
ROE
55.2%Net income as a percentage of shareholders' equity. Similar to ROIC but counts only the equity side.Above 20% is strong, but can be inflated by leverage — a heavily indebted company can show high ROE with weak underlying ROIC.
Gross margin
80.6%Revenue minus the direct cost of producing what was sold, as a percentage of revenue. The first read on whether the product is structurally profitable.Software / SaaS is typically 70%+; consumer goods 30–50%; commodity / hardware businesses can be under 20%.
D/E
-2.4Total debt divided by shareholders' equity. Measures how much the business runs on borrowed money versus owner capital.Under 1 is conservative; 1–2 is typical for mature businesses; over 2 is leveraged and more sensitive to interest rates.
