Impact Evaluation

• Market Cap Context: For Castellum, a company with a $110 million market cap, this grant is a material component of executive compensation.
• Ownership Concentration: This grant establishes the COO's initial derivative position in the company, aligning his financial interests with future stock performance.
• Dilution Impact: The 275,000 options, if exercised, would increase the total number of shares outstanding by approximately 0.30%. While not a large immediate dilution, it is a notable figure for a company of this size and contributes to the overall potential dilution from incentive plans.
• Transaction Significance: The significance is rated 'Medium' not due to the dollar value (which is $0 for a grant), but because the number of potential shares represents a meaningful percentage (0.30%) of the total shares outstanding, falling into the significant range for materiality assessment (0.25-0.5%).
