Palo Alto Networks shares fell in after-hours trading Tuesday after the cybersecurity giant issued profit guidance that missed Wall Street expectations. The company reported fiscal second-quarter earnings of $1.03 per share on revenue of $2.59 billion, beating analyst estimates of 94 cents per share on $2.58 billion.

The disappointing guidance came as Palo Alto slashed its full-year earnings per share forecast to $3.65-$3.70, down from its previous range of $3.80-$3.90 and below the consensus estimate of $3.87. For the current quarter, the company expects earnings of 78-80 cents per share on revenue of $2.941-$2.945 billion, falling short of estimates calling for 92 cents per share on $2.61 billion in revenue.

Despite the strong quarterly results, investors reacted negatively to the reduced profit outlook, sending shares lower in extended trading. The guidance cut suggests potential headwinds in Palo Alto's business as the company navigates a challenging enterprise spending environment, raising questions about the sustainability of its growth trajectory in the competitive cybersecurity market.
