Are GasGas and KTM the same?

I've been hearing a lot about GasGas and KTM in the motorcycle community, and I'm wondering if they're actually the same. Is GasGas a subsidiary of KTM? Are their bikes manufactured in the same facilities? Do they share design elements or technology? I'm curious about the relationship between these two brands and if one is essentially a rebranded version of the other. I've seen some similarities in their models, but is it just a case of convergent evolution, or is there a deeper connection between GasGas and KTM? Clarifying this for me would help me make an informed decision when considering a purchase.
