After a quick review of MNKD's second quarter financials, you can see how its balance sheet and income statement are so closely tied together. It seems to be sitting on a serious inventory of Tyvaso DPI, and until it is sold to UTHR, it will remain a liability on the MNKD balance sheet. As Tyvaso DPI inventory is sold and transferred to UTHR, Tyvaso DPI royalties will be in a position to grow, as that current Tyvaso DPI inventory will move from MNKD's liability to UTHR's asset on UTHR's balance sheet and eventually, to a potential sale, resulting in royalties due to Mannkind.
As for Afrezza and V-Go, hopefully, the new marketing strategies for both will improve revenues to the point where they can be profitable. Both products seem to be needed, IMHO. The Mannkind sales force is probably getting tired of the constant change, with questionable results.
