Chris, I may be reading the web page wrong, but I think they have multiple booths. The combined square footage is the second largest at the show. Unfortunately, I don't think that guarantees anything since they appear to have been waiting on some kind of news that has not yet arrived.
3 Booths totaling 9,100 Sq ft.
Genentech is the largest presence at 10,000 sq ft. I think NW might be #2.
AbbVie has 4900 sq ft and a market cap of $98B
Booth Space Dimensions
#10147 4500 sq Ft 90’ x 50’
#10155 4000 sq Ft 80’ x 50’
#Reg85 600 sq Ft 30’ x 20’
