Haram revenue in loss making R&D companies

I have studied the excellent investment courses arranged by Brothers Mohsin and Ibrahim. JazakAllah Khair for the effort.

I am finding difficulty in assessing companies that are mostly R&D and are relatively loss making like certain healthcare/pharmaceutical or Technology companies. While assessing the revenue, their financial non operating mostly interest paying revenue is always dominant and therefore these companies do not comply with screening platforms like Zoya.
In view of their halal core business and excellent prospects, I need opinion from the experts regarding the permissibility.
A typical example of a such company is Moderna “MRNA” a vaccine making US Company. In fact, there are plenty of such good companies in health and technology sectors.
