Option #3 is invalid.
Not at all.
"should has [sic] paid an installment in June or latest in July... The company needs money, there is no tolerance for late payment, if it still did not paid by Sept 30 Stephen would put the collaboration on hold or even end it."
Maybe. You don't know. You haven't seen the agreement. And even if that was the agreement and it didn't happen, that doesn't necessarily mean that QMC ended the deal. You don't know.
Any money received between June and September will be reported in Q3 Report as revenue, the management has no obligation to report such insignificant collaboration fee in a particular PR.
No. You're wrong again. June is in their Q4 and money received in June would show up in the 10-K (not necessarily as revenue, but it would show up somewhere). That's required under GAAP. July-Sep is their Q1. And Ks and Qs are not PR. How do you come up with this nonsense?
