From Christian Davenport:

That was a tough blow for Virgin Orbit, which is really struggling. They needed that launch to go well. Like a lot of companies that went public via SPACs, they are now beholden to the public markets, which don't look kindly on failures even though that is a normal part of the rocket business, especially at first. A quick Google search shows their stock price down 83 percent in the last year. Richard Branson's Virgin group has continued to invest in the company but it is clearly going through a tough time at the moment.
