Management Comments

Industry Context

StockSavvy.ai notes that equity-based compensation for directors is a standard industry practice among aerospace and data-as-a-service companies to ensure board members are incentivized to drive long-term stock performance.

Comparison to Industry Standards

• The one-year vesting cliff for director RSUs is consistent with governance standards at peer companies such as BlackSky Technology and Planet Labs.
• The use of in-kind distributions from holding companies to individual directors is a common method for simplifying personal estate and tax planning in the technology sector.
