Is UNFI a big company?

Hello there, I'm curious about UNFI. I've been hearing a lot about this company lately, and I'm wondering if it's considered a big player in its industry. Could you elaborate on UNFI's size and market position? Are they a major competitor, or do they occupy a niche market? It would be great if you could provide some insights into their financial performance and growth potential as well. Thanks in advance for your help!
