"I think they have 4 business days to do that" That's the 8-K filing requirement, for sure.
Did the co-signers referenced here escape their responsibility? As far as I could tell IMR hasn't been mentioned in an IPIX 10-K filing since 2018. "In September 2013, Cellceutix Corporation signed a lease extension agreement with Cummings Properties whose term began on October 1, 2013. The lease is for five years ending on September 30, 2018, and requires monthly payments of $17,000. Innovative Medical Research Inc., a company owned by Leo Ehrlich and Dr. Krishna Menon, officers of Cellceutix, needed to co-sign the lease. Innovative Medical Research is subleasing 200 square feet of space, space previously leased by Cellceutix from Kard (see below) and pays Cellceutix $900 per month. Innovative Medical Research Inc. is not engaged in work for Cellceutix." (underlining and bold mine)
