Santander Consumer USA registered with the Securities and Exchange Commission to sell more than 14 million shares — 4% — of its outstanding stock. As of the Aug. 13 SEC filing, SCUSA’s share price was $17.82. An industry analyst who follows SCUSA told Auto Finance News that registration requirements for significant shareholders are fairly customary. If SCUSA ultimately sells all the registered shares, the event would be “very surprising,” the analyst said.
