EU is #2 (behind the US) in terms of net sales accounting for 26% in 2024. There is no "or else".

I would think profits are more important than sales.

The EU can write itself a check for up to 26% of Apple's annual revenue (6% + 20%). Coincidentally, that's the same as your 26% number for Apple net sales from the EU. But if Apple gets fined 26%, that represents a huge loss of capital since they still have to pay for COGS, pay taxes, pay employee salaries, and so forth.

I would consider it incredibly unlikely to happen, but based on how much money they're banking, I'd say Apple could probably afford to live without the EU.
