Could also be (the seller) somebody willing to buy at 8.90 (10 strike - 1.10 option premium) or happy to pocket 1.10 if put expires worthless. Seller could be a short willing to cover at 8.90 and happy to have 1.10 to offset his underwater position if option not exercised.
I think the buyer has a screw loose. Short monkey being the buyer would not surprise me.
I think they are trying to keep a lid on the price. A secondary discount from 10.00 is cheaper than a like discount from 10.75. Hamo's job is to make money, not punish shorts. If he needs common equity to make accretive investments, the fact that a secondary gives shorts a massive cover buy without a spike will not deter him.
Shorts have dug themselves into a deep hole, which is going to get deeper with the dividend and new cad estimate. They need a nrf bombshell, market meltdown or interest rate spike to get sufficient sell volume to cover. Without that they need a secondary. Otherwise, there are 30 million short shares going deeper under water without the sell volume to avert a squeeze. Death by a dime a day or death by a massive squeeze. Ugly choices.
