First: Revenue stopped growing:

'22: 418,933

'21: 464,700

'20: 406,785

'19: 297,897

Second: They have never made a profit

Depending on what you have paid for it, I would exit. If you paid $100+, it is too late, you may as well hold it to zero. If you recently bought it, I would sell immediately, before it goes down further.

My simple rule of investing: a corp needs to be either growing, or be profitable. If it is neither, it is dead.
