it may well be but it would be foolish to stick your neck out. If this is a direct client, ask. In the absence of an answer, I would enter a comment in the text explaining what you imagine BUT insisting that they check it out. You could even do this for an agency (I don't work with agencies so I'm on uncertain ground here). When I put comments in the body of the text, I also call the client's attention to their presence in the covering mail, in red to make sure they don't miss the note and use the text without cleaning up the(ir) mess.

My first instinct was indeed to look this up, but the search did not provide much help. The company doesn't appear to have its own website (it may be just a holding company), and its share capital is only around 15 million euros, which certainly wouldn't make it number 1 in any major category.

maybe not 1 (2,3..) - look the firm up on internet to see what its ranking actually is
