Adapting to the winds of change under the pandemic threat

Every generation needs a revolution - an entrepreneurial revolution

I know of an officer of a diagnostic center who had so good during the pandemic.   From an x figure prior to the pandemic their revenues rose 8 fold:   they offered antigen tests and RT PCR when they were in their high nearly 5 digits price.  They are tied up with a big local airline

Their stockholders increased in number and called for additional subscription

Now 1.  the covid cases has fallen 120/th of their peak 2.   the RT PCR is no longer required for travel

         to tourist destinations  and 3.  such location offer free rapid tests

The said officer indicated that their revenues are declining.  What are they supposed to do
