RE:RE:RE:RE:RE:PP = Win, Win Situation...Hate to say it, but, wildbird1's, homework showed some flaws.
You can't make a prognosis based on Working Capital alone. This is simply not possible.
Another poster, 2b7f6fab, did a much better job:
From the 6/30 financials : Cash $932 K + Accounts Receivable $1344 K - Accounts Payable $ 592 K + Warrants Exercised after 6/30 $ 853 K - Operating Exp. @ $500 K / month estimate $ 1,500 K = $ 1000 K approximate cash balance at the end of September.
My estimation is somewhat more conservative : $ 500 K approximate cash balance at the end of September.
