Well, they won't be able to hold off on announcing their earnings indefinitely. I believe that the SEC rules require them to file their 10-Q within 40-45 days of their fiscal quarter end.
I would be very surprised, however, to see them presenting at investor conferences until this very material issue is resolved.
Someone asked earlier about the ability of insiders to divest shares through non-public channels without having to disclose such divestments. The relevant disclosure rules are concerned with "beneficial ownership," so they are triggered regardless of how an insider disposes of his or her shares or whether he or she holds the shares indirectly such as through a trust or pass-through entity.
