I can see the point you are trying to make but in this case here they are behind much more than this 10k for 2021. The last Q they filed was for end of 2019 which was their Q3 since they don't have a regular fiscal year, even if they filed the 10k for march/21 which they filed the NT for, they would need to file the entire year of 2020 which they never filed an NT for either. They can't just miss out on these 2020 filings.
I do hope that they come through as you said but also for the entire year 2020 otherwise they won't get current anyway.
