Qualcomm (QCOM) shares plummeted 5.7% in after-hours trading on Wednesday following the company's disappointing third-quarter revenue forecast, which fell short of analysts' expectations. The chipmaker's cautious outlook reflects growing concerns about the macroeconomic environment and global trade tensions.

For the current fiscal quarter, Qualcomm expects revenue between $9.9 billion and $10.7 billion, with the midpoint of $10.3 billion falling below the consensus estimate of $10.35 billion. The company's adjusted earnings per share forecast of $2.60 to $2.80 was more in line with expectations, with the midpoint slightly above the $2.67 per share analysts had projected.

Despite the gloomy outlook, Qualcomm reported strong results for its fiscal second quarter ended March 30. The company posted earnings per share of $2.85, surpassing the Wall Street consensus of $2.82. Revenue came in at $10.98 billion, beating estimates of $10.66 billion. However, these positive results were overshadowed by the cautious forward guidance, leading to the sharp sell-off in after-hours trading.

CEO Cristiano Amon addressed the challenges ahead, stating, "As we navigate the current macroeconomic and trade environment, we remain focused on the critical factors we can control – our leading technology roadmap, best-in-class product portfolio, strong customer relationships and operational efficiencies." The comments suggest that Qualcomm is bracing for potential headwinds in the coming months, particularly as global trade tensions and economic uncertainties persist.
