After speculators spent all evening yesterday estimating the gain of Roaring Kitty’s portfolio on GameStop (NYSE: GME) due to strong after hours action, the equity is tumbling in early morning trade today following the filing of a prospectus supplement by the company.

GameStop has filed to sell an additional 75 million shares under an at the market offering, which follows a prior at the market offering that saw 45 million shares sold for gross proceeds of $933.4 million. The latest offering is to be conducted through an open market sale agreement that is in place with Jefferies LLC.

The filing has seemingly resulted in a wake-up call for investors, whom last night bid the equity as high as $65.81 in after-market trading. Following the filing, the equity is down 17% to $38.50 in pre-market trading.

The sharp tumble follows speculation among market watchers last night that Keith Gill, whom is more commonly known as Roaring Kitty, had reached billionaire status if the price of the equity were to hold from after market trading.

GameStop meanwhile reported its first quarter 2024 results this morning, posting net sales of $0.882 billion, from from $1.237 billion during the same period last year. Net loss for the period was $32.3 million, down from $50.5 million a year ago, while cash and cash equivalents totaled $1.083 billion.
