Why should they share it??? I would not share it if I was running the company, not till the FDA had rendered a decision. The CEO has made it clear in the interview the status of the 510K and many other items, the information is acceptable to me and many other shareholders...
What purpose would having the number serve? The FDA makes no information about a 510k application available to the public until they have a final decision. The FDA updates their data base weekly for final decisions. You can type a non-finalized "k number" into a FDA data base all day long and receive "no results" each time.
