S3 BLACKLIGHT: Mattress Firm Shorts Wake Up to a $188 million Nightmare

South African furniture retailer Steinoff Intl Holdings (SNH SJ) agreed to acquire Mattress Firm Holding Corp (MFRM US) for $64/share, a 115% premium, or $2.4 billion.

MFRM short interest peaked in July 2015 at $332 million when the stock hit $62.77. By yearend its stock price dropped 29% and short interest was down to $264 million. Short interest remained steady from January to July 2016, ranging between $200-$300 million. As MFRM’s stock price dropped to a YTD low of $29.14 after they issued a profit warning for 2016 due to a $139 million rebranding charge. Some short sellers covered their positions to realize their profits and as of Friday, August 5th there were 5.5 million shares short, down $78 million from the end of the 2nd quarter.

If the remaining short sellers had their positions open from the beginning of the year they were sitting on $82 million of unrealized profits. Steinoff’s $64 offer rocketed Mattress Firm’s stock price up over 114% and generated a one day unrealized loss of $188 million. Year-long Mattress Firm short sellers went from a $14.89/share profit to a $19.09/loss or $106 million in unrealized losses.

The cost to borrow MFRM stock increased today as well. Stock borrow costs were already expensive at a 16% fee, and today MFRM stock borrows are trading between 15% and 20% fee. We are expecting a large amount of buying to cover in the next several days with a large portion of the existing 5.5 million short shares closing out their positions. Borrow rates should drop significantly as stock is returned to lenders by the end of the week.
