(Reuters) -HP Inc cut its annual profit forecast on Wednesday as it expects a moderation in PC market growth at a time when the global economic environment remains volatile, sending its shares down 14% in extended trading. The uncertainty surrounding U.S. tariffs and associated inflationary pressures will negatively impact demand for personal computers in the following quarters in 2025, research firm IDC said last month. HP is seeing the biggest cost impact in its Personal Systems segment, CFO Karen Parkhill said.
