SentinelOne Slides 8% as Trimmed Profit Forecast Outweighs Revenue Beat, CrowdStrike Declines 7%

SentinelOne (NYSE:S | S Price Prediction) delivered a revenue beat and a record operating margin, yet a trimmed full-year profit outlook is what investors focused on Friday morning. The reaction pulled the broader cybersecurity group lower even as the S&P 500 held steady, a rare split between a specific-name catalyst and the broad market.

SentinelOne stock is down 8% to $20.94 after the company trimmed full-year adjusted EPS guidance to $0.31 at the midpoint. Meanwhile, CrowdStrike Holdings (NASDAQ:CRWD) stock is down 7% to $210.98 in a sympathy move, despite the company reporting its own strong quarter earlier this week.

The First Trust NASDAQ Cybersecurity ETF (NASDAQ:CIBR) is down 0.7% to $100.13, reflecting the sector giving back ground broadly. At the same time, the SPDR S&P 500 ETF Trust (NYSEARCA:SPY) is up 0.1% to $771.74, so the broad market holds firm while cybersecurity trims a stretch of very strong gains.

Trimmed Profit Forecast Outweighs a Revenue Beat

SentinelOne reported fiscal Q2 2027 revenue of $292 million against analyst estimates of $290.2 million, up 20.6% year over year for a 0.6% beat. Adjusted operating income of $30.53 million against $24.24 million expected was the real bright spot, delivering a 10.5% margin. Customers paying more than $100,000 annually reached 1,715, an increase of just 13 from the previous quarter, a noticeably slower pace than in recent periods.

The problem was SentinelOne’s forward guide. Full-year adjusted EPS guidance was cut to $0.31 at the midpoint, an 11.4% decrease, while next quarter revenue guidance of roughly $310 million was close to estimates rather than above them. SentinelOne CEO Tomer Weingarten emphasized the platform story, saying the quarter demonstrated “a top-tier growth profile, accelerating platform adoption, and undisputed technology leadership for both AI for Security and Security for AI.”

Peers Follow the Move as the Valuation Debate Reopens

CrowdStrike stock was up 95% year to date through Thursday’s close, so Friday’s slide takes only a modest bite out of that run. Also, Zscaler (NASDAQ:ZS) stock is down 1% to $185.29, while Okta (NASDAQ:OKTA) stock is off 0.9% to $171.36 as identity and cloud security names trade with a softer tone.

Palo Alto Networks (NASDAQ:PANW) sits at the center of the valuation debate around SentinelOne shares. The bulls note that SentinelOne stock trades at a valuation discount to CrowdStrike and Palo Alto Networks, while the skeptics point to today’s softer profit guide and slower large-customer growth as reasons to stay patient with SentinelOne shares. Today’s move widens that valuation gap somewhat, though it does so for reasons tied to the profit trajectory rather than to top-line concerns.

SentinelOne stock was up 51% year to date through Thursday’s close, so this drop pares only a slice of a very strong 2026. The setup from here depends heavily on whether the profit path can widen without further guidance cuts, since top-line growth clearly came through this quarter. That makes the durability of margin expansion the key question for SentinelOne stock over the next several reports.

Historically, SentinelOne shares have often struggled on results days even when the headline numbers came in ahead. Today’s 5% slide compares with the historical average day-of change for earnings beats of -4.2%, so the reaction fits a familiar pattern for this name rather than signaling a fundamental break in the story.

What to Watch

SentinelOne’s conference call has already wrapped, so the analyst reaction is now the story. Investors can watch for price target revisions and any commentary on whether the softer profit guide reflects reinvestment for growth or genuine margin pressure emerging in the model.

The cybersecurity group’s next test is whether CrowdStrike stock, Zscaler shares, and Okta shares find footing this afternoon or whether the pullback deepens through Friday. Investors should keep their position sizing modest here given how sharp the recent rally has been across these names, particularly with valuations across the group still elevated relative to the broader software space. A gradual scaling approach may be the more prudent way to add exposure to their cybersecurity positions after a move of this magnitude.
