Why Synopsys Stock Jumped 13% on Thursday After Its Investor Day Guidance
Synopsys (SNPS) stock jumped 13% on Thursday, October 1, after the chip-design software maker guided fiscal 2027 revenue and earnings well above Wall Street’s estimates at its Investor Day in New York. Shares closed at $491, up from $435 the day before.
Management guided revenue of $11.10 billion to $11.20 billion, about 15% growth, against the $10.81 billion analysts expected. Non-GAAP earnings per share of $19.04 to $19.12 beat the $17.81 consensus by a wider margin. The operating margin target of 44% adds 250 basis points to fiscal 2026’s 41.5%.
The long-term model moved up as well. Synopsys now targets 15% annual revenue growth through fiscal 2030, up from double digits, and an operating margin of about 50% by then, versus a prior mid-40s goal. CFO Shelagh Glaser also pulled the $400 million cost synergy target from the ANSYS deal forward a year, to fiscal 2027, and announced a $1 billion buyback over the coming months.
Two partnerships carried the AI argument. Amazon Web Services signed a multi-year deal worth more than $1 billion to license chip-design IP for multiple generations of its custom silicon. CEO Sassine Ghazi said that figure covers license fees only: royalties start once designs reach production, roughly 14 months out, and none land in fiscal 2027.
OpenAI will build GPT-Synopsys, a chip-design model trained on Synopsys tools, under a revenue-sharing agreement. OpenAI pays a training subscription fee, and customer revenue then splits based on how much the model improves a chip. “We structured the agreement in a way that it will not be cannibalizing our business,” Ghazi told Reuters.
That deal answers the worry that AI models could replace EDA software, and it landed on a stock that entered the event down 7% for the year. The jump pays for signed contracts and hard guidance.
