Qualcomm (QCOM.O) gave a weak outlook for current-quarter revenue, highlighting concerns that tariffs will hurt demand for its products. The company said on Wednesday that revenue for the quarter ending in June will be between $9.9 billion and $10.7 billion. The midpoint of the range was slightly below the average analyst estimate of $10.33 billion, causing its shares to fall after the bell. Qualcomm's CEO said the company is navigating the "current macroeconomic and trade environment." The outlook revived concerns that the smartphone market will be hit by an imminent trade war. Qualcomm is seen as highly vulnerable to the threat of U.S. tariffs. Intel and other companies have given cautious outlooks, with some even warning that the economy may be heading for a recession. Qualcomm shares fell more than 6% after the bell.
