Palo Alto Networks Inc. (PANW) did everything right last quarter. It beat on revenue, beat on earnings, and raised guidance. So why is the stock having its worst two days in nearly three years?
Shares fell 5.2% Tuesday to $362.09, then dropped another 8% Wednesday to roughly $330. That's a two-day slide of 13.2%, the steepest back-to-back move since February 2024, when a guidance cut wiped out more than a quarter of the stock in a single session.
The culprit? A 100-basis-point hit to gross margin. In fiscal Q4, gross margin came in at 74.8%, down from a year earlier. On the earnings call, management said cloud hosting costs will grow faster than revenue in fiscal 2027, and memory and storage costs are expected to stay elevated. Investors apparently didn't like the sound of that, even though the numbers themselves were strong.
Let's look at the good stuff first. Fiscal fourth-quarter revenue grew 34% to $3.41 billion, beating the $3.35 billion analysts expected. Adjusted earnings came in at $1.02 a share versus 98 cents consensus. And the company guided fiscal 2027 revenue to $14.10 billion to $14.20 billion, roughly $300 million above what Wall Street was looking for.
So the business is growing, and management is confident enough to guide above expectations. But the margin compression is a reminder that even the best cybersecurity companies aren't immune to rising costs. Cloud infrastructure is expensive, and as Palo Alto scales its platform, those costs are eating into profitability.
For retail investors, the takeaway is nuanced. The stock's reaction shows that in today's market, a beat on the top and bottom lines isn't always enough. If margins are shrinking, investors will punish you. But the underlying fundamentals remain solid, and the guidance raise suggests management sees a clear path forward.
Whether this two-day drop is a buying opportunity or a warning sign depends on how much weight you put on margin trends versus growth. Either way, it's a reminder that even the best-laid plans can get a rough reception when costs creep up.
