During the economic downturns of 2008 and 2009, many US restaurant companies struggled to avoid heavy losses. However, some stil

If you are asking/wondering if this affected their business(ess) then I would have to say yes. I said yes because it says "Many US restaurant companies struggled to avoid heavy losses." (key word(s) is/are Avoid and Struggled to) which means some of them, including McDonalds probably did avoid this and some other McDonald's didn't avoid this.
(hope I answered this for you and if so I hope I did a good job)
