Cadence put up quarterly revenue of $1.58 billion, up 24.2 percent year over year, and raised its annual guidance to a range of $6.26 to $6.34 billion against a consensus near $6.21 billion. The stock added more than four percent after hours. The number that matters is not the 24.2 percent. It is the guide raise, and specifically its timing: it landed on the same session in which ASML fell more than seven percent, Applied Materials more than six, and Lam Research more than seven on a report that a Chinese state-backed manufacturer has begun building deep ultraviolet lithography machines.
