• The appeals court found the district court failed to evaluate market-inefficiency evidence or properly consider arguments about meme-stock dynamics.
• The ruling did not determine whether the company's securities traded in an efficient or inefficient market.
• Class certification proceedings will return to the U.S. District Court for the Western District of Texas.
