Item 5.07 Submission of Matters to a Vote of Security Holders.
We held our 2026 Annual Meeting of Stockholders on June 10, 2026. The board of directors solicited proxies pursuant to a proxy statement that we filed with the Securities and Exchange Commission under Section 14(a) of the Securities Exchange Act of 1934 on April 27, 2026. There was no solicitation in opposition to the board’s solicitation.

Each share of Class A common stock was entitled to one vote with respect to each matter submitted to a vote at the meeting, and each share of Class B common stock was entitled to twenty votes with respect to each matter submitted to a vote at the meeting. Shares of Class A and Class B common stock representing 135,814,497 votes, or 84.32% of the total votes attributable to all outstanding shares of Class A and Class B common stock, were present in person or by proxy at the meeting.
