The probe follows the company’s July 30 earnings report, which revealed revenue of $1.01 billion—falling short of expectations—and revised guidance citing economic uncertainty and reduced demand for its dental products. The firm is examining whether Align’s leadership misled investors through material disclosures or operational practices during this period.
