After a reverse split, it is common for that stock price to decline. Not for any good reason, but because traders see RS as a negative thing and many sell. Having just gone through one on another stock, I sold 1/2 my shares before the split and hung onto the rest. After the split, the price dumped (for a different reason) and I bought back in as it was dropping. It eventually ended up below the pre-split price. (But it won't stay there.)
They are not all the same, but in this particular case, the OS was already maxed, and a note matured. They could not convert, and got disgruntled. The moment the RS was made active, they converted, and immediately dumped them on the market, dropping the price. Unfortunate, but it was going to happen one way or the other, it was just bad for shareholders because their shares were locked for 3 days by the brokerages, and that's when the creditor dumped. We sat by watching the decline. You can always CALL the brokerage to sell, if that's your inclination.
