At least three new billionaires joined the three-comma club on Wednesday after Fermi America, an Amarillo, Texas-based real estate investment trust cofounded by former energy secretary and Texas governor Rick Perry, went public on the Nasdaq. The stock opened at $21 and closed 55% higher at $32.53 per share, valuing the nine-month-old firm at $19 billion, despite the fact that it has yet to generate any sales.
