Depends on the definition, doesn't it? E.g. would you consider an iPhone to be American? If going by "made in" of parts and final assembly, then no, but if going by where the HQ of the final product's company is at, then yes?
Or would the definition be about IP specifically? And in that case, would e.g. Rolls-Royce be considered to be German since it is a subsidiary of a "German company"?
And then there is also the question about whether it is not a bit too simple to attribute a nationality to the private market. E.g. Tesla, it is not owned by the U.S., is it? And if Mr Musk becomes a Chinese citizen tomorrow and moves the HQ of Tesla to Mexico and additionally perhaps sells a majority of shares to Saudi Arabia, then "what" would Tesla be?
