CrowdStrike and Palo Alto Networks plummet after earnings reports; cybersecurity stocks pour cold water on the “software stock rebound.”

```

Despite delivering financial results that exceeded Wall Street expectations, cybersecurity giants CrowdStrike and Palo Alto Networks still suffered sharp share price drops on the latest trading day. This has poured cold water on the recent strong rebound in the software and cybersecurity sector.

In after-hours trading on Wednesday, CrowdStrike’s stock plunged 10%. Previously, even though Palo Alto Networks reported core financial figures above expectations, its stock fell 5.6% during Wednesday’s regular session.

This sell-off highlights a subtle shift in market sentiment, as investors have begun to scrutinize financial details of leading companies in the sector more harshly. The sharp declines also confirm previous market concerns: after the historic surges in recent months, extreme valuations set the stage for profit-taking, making it difficult for “better-than-expected earnings with raised guidance” to stem selling pressure.

Although corporate executives and Wall Street analysts continue to emphasize the essential role of cybersecurity in the AI wave, the latest market reaction shows that sky-high expectations have already been priced into top tech stocks, and the resilience of the cybersecurity sector is facing a stern test.

Earnings Exceed Expectations, but Share Prices Still Decline

From a fundamental perspective, CrowdStrike’s latest financial results remain robust. In the first fiscal quarter, the company achieved revenue of $1.39 billion, up 26% year-over-year and above analyst expectations of $1.36 billion. Adjusted EPS reached $1.10, well above the $0.73 from the same period last year and also exceeding analysts’ estimate of $1.07.

Based on strong business performance, CrowdStrike raised its full-year FY2027 revenue guidance from $587 million–$593 million to $591 million–$596 million, higher than the analyst expectation of $590 million. In addition, the board announced a 4-for-1 stock split for Class A common stock. According to FactSet, five S&P 500 companies have executed stock splits this year.

However, these impressive financials failed to please Wall Street. In the current macro and market environment, investors in the cybersecurity sector are looking for reasons to nitpick the financial results of leading companies, causing share prices to come under pressure immediately after earnings releases.

It is worth noting that to understand the sharp price drop following Wednesday’s earnings, one must look back at the market background prior to Tuesday’s results. Heading into this earnings season, cybersecurity was one of the few true bright spots within technology.

Palo Alto Networks’ share price soared 57% last month alone, while CrowdStrike surged 64% in May. In 2026 trading, both stocks have risen by over 60%, setting all-time highs and ranking among the 30 best performers of the S&P 500 this year.

This rally was mainly fueled by the market’s broad enthusiasm for AI beneficiaries. After the Global X Cybersecurity ETF marked its best single-month performance since its 2019 launch (a 37% jump) in May, its year-to-date gain is 27%. In contrast, the iShares Expanded Tech-Software ETF has advanced just 1.9% so far in 2026.

These extreme gains paved the way for this week’s declines. Prior market analysis had already warned that, no matter how strong the earnings, the recent surges in Palo Alto Networks and CrowdStrike may limit further upside for their stocks.

Investors viewed the better-than-expected results as a perfect opportunity to lock in the massive profits from the past month, triggering a wave of selling. Luke Rahbari, portfolio manager at Rational Equity Armor Fund, previously noted that he does not expect these cybersecurity stocks to surge 47% like Dell Technologies did on strong AI server demand.

AI Remains the Core Narrative

Despite short-term share price pressures, artificial intelligence remains the industry’s central theme.

CrowdStrike CEO George Kurtz stated that in the first quarter “the worlds of cybersecurity and cutting-edge AI collided” and emphasized that CrowdStrike is the “foundational AI security infrastructure, which is crucial to successful AI adoption.” This year, the company was selected as a cybersecurity partner for Anthropic to test its Claude Mythos model and also participated in OpenAI’s related safety initiatives.

Jordan Klein, Managing Director at Mizuho Securities USA, pointed out that market sentiment was gloomy earlier this year due to fears that AI models might disrupt the industry, but investors soon realized that AI would, in fact, create more security demand.

However, the divide between ‘winners’ and ‘losers’ within the cybersecurity sector is widening. Last week, Zscaler’s stock plunged 32% the day after issuing revenue guidance below expectations, setting its worst single-day performance on record.

According to Bloomberg Industry Research analyst Mandeep Singh, Zscaler’s suite lacks identity-security features for AI agents, which may limit its ability to land big deals, while also facing competition from larger rivals like Palo Alto Networks and Fortinet, who offer bundled platforms.

Jefferies analyst Joseph Gallo believes that this performance gap reflects a preference for large platform leaders, who benefit from vendor consolidation trends and are seen as more resilient in the AI era. In the current earnings season, the market’s focus has shifted entirely to the actual benefits brought by AI.
