This Schedule 13D/A filing indicates a substantial reduction in holdings by Viking Global Investors, a major institutional investor. The sale of approximately $107.3 million worth of shares, representing a notable portion of the company's market capitalization, appears to be a strategic portfolio adjustment or profit-taking.
