2. 2

   Advisory approval of executive compensation (Say-on-Pay

   ManagementBoard: FOR

   Non-binding, advisory vote to approve the compensation of the Company’s Named Executive Officers as disclosed in the Proxy Statement.

   More detail

   This advisory (non-binding) proposal asks shareholders to approve the overall compensation of the Company’s Named Executive Officers as described in the proxy materials. Management is seeking this advisory approval to confirm stockholder support for the Company’s pay-for-performance philosophy, which emphasizes a high percentage of at-risk compensation (e.g., 93% of the CEO’s target compensation is at risk) and long-term incentives tied to multi-year operational and relative TSR metrics. The Compensation Committee uses a mix of short-term incentives tied to Adjusted EBITDA, revenue and AFFO per share, and long-term performance units (PUs), RSUs and, for the CEO, stock options, designed to align executive interests with long-term stockholder value. The Company highlights strong recent operational results (record revenue, Adjusted EBITDA and AFFO in 2025), sustained relative TSR outperformance versus peers, and prior strong Say-on-Pay support (approximately 96% in 2025) as evidence of alignment between pay and performance. The Board emphasizes governance safeguards such as an independent Compensation Committee, an independent compensation consultant, executive and director stock ownership guidelines, a clawback policy, and limits on hedging and pledging to mitigate misalignment and risk-taking. Because the vote is advisory, it will not be binding, but the Board and Compensation Committee will consider the outcome when making future compensation decisions. The Board recommends a vote FOR because it believes the executive compensation program appropriately rewards achievement of strategic and financial objectives, aligns pay with long-term value creation, and incorporates robust governance oversight and risk mitigation measures.
