What happens if a stock never reports their earnings for a quarter?

I was researching Embark Technology Inc. and I noticed they just never reported their Q4 ‘22 earnings despite it already being time to report Q1 ‘23. Is it legal for a company to never report earnings to shareholders? (I’m not a shareholder, just asking hypothetically) Could they miss two reports in a row? I tried googling all these questions and got 0 straightforward answers. Any clarification on this would be greatly appreciated!
