Synopsys Withdraws Forecasts Amid China Export Restrictions

Okay, so get this. Synopsys, you know, the company that makes software to design those little chips, totally pulled a fast one. Like, they just put out their yearly and quarterly money predictions, and then BAM! A day later, they just said, 'Nah, never mind.'
Why? Because of new rules from the U.S. saying they can't sell their stuff to China so easily anymore. That's a HUGE market for them, so yeah, that's a big deal. Their stock price even went down a bit after all this happened.
They got a letter from some government bureau, the BIS, telling them about these new rules after they already told everyone how much money they expected to make. Now, they're like, 'Uh oh, we gotta figure out what this means for us.'
Apparently, the U.S. basically told a bunch of companies to just stop sending things to China without getting special permission, and they even took back permissions they already gave out! Reuters heard about this from people who know what's going on.
Companies that make this chip design software, like Synopsys, Cadence, and even Siemens EDA, got letters last Friday saying they needed a license to send things to China now. Siemens is saying they'll work with their customers to try and make things okay, which is cool I guess.
Cadence also told everyone in a document on Thursday that the same government bureau told them about the need for licenses last Friday too. They said these new rules are kinda complicated, and they're talking to the BIS to get a better idea of what's going on so they can figure out how it'll hit their business and their money.
These new rules are probably gonna make things even more tense with China. It seems like the U.S. is trying to stop China from getting the things they need for important industries. Kinda makes you wonder what's gonna happen next, right?
