if you google that language, like I just did, you'll find it's standard boilerplate...here are a few other instances:
As of March 31, 2020, 370,102,805 shares of our common stock were outstanding and held by 125 stockholders of record. The actual number of stockholders is greater than this number of record holders and includes stockholders who are beneficial owners but whose shares are held in street name by brokers and other nominees. This number of holders of record also does not include stockholders whose shares may be held in trust by other entities. (taken from https://investors.modernatx.com/node/9031/html )
