That's Coca-Cola GmbH, a German company that was owned by a US company. When the US and Germany were at war the US Coca-Cola lost control of Coca-Cola GmbH. It wasn't until after the war that the US company got control back.
A distinction that matters somewhat in the context of the comparison to IBM, but given that the two Coca-Cola companies recombined after the war, it’s one of little difference.
