Corporate Governance and Shareholder Structure - Expedia Group controls 61.2% of the company's issued share capital and 84.3% of voting power, limiting other shareholders' influence[107]. - The company has a dual-class share structure where Class A shares have one vote per share and Class B shares have ten votes per share, limiting the influence of Class A shareholders[122]. - The company is classified as a "controlled company" under Nasdaq rules, allowing it to opt out of certain corporate governance standards[132]. - U.S. investors may face difficulties in enforcing civil liabilities against the company or its directors due to its Dutch incorporation and the lack of reciprocal enforcement treaties[127].
