Synopsys shares exploded higher yesterday following a highly successful Investor Day where the company issued fiscal 2027 revenue guidance of up to $11.2 billion, handily exceeding analyst expectations of $11 billion. This optimistic outlook was bolstered by the announcement of major multi-year strategic partnerships with Amazon Web Services and OpenAI, both of which are leveraging Synopsys tools to accelerate custom chip design. The positive sentiment was further amplified by the company's projection of robust 44% non-GAAP operating margins and $3.1 billion in free cash flow for 2027, prompting a wave of price target increases from Wall Street analysts.
