Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Total revenue increased 133% year-over-year, driven by a 109% increase in rental revenue and a 326% increase in fuel revenue. Growth was attributed to the acquisition of the Camarillo (CMA) campus, commencement of operations at San Jose (SJC), and improved occupancy at Nashville (BNA) and Miami-Opa Locka (OPF).
• Expense Increases: Total expenses rose 63% to $12.42 million. Ground lease expenses increased 136% due to new leases at SJC, Orlando (ORL), Washington Dulles (IAD), and Salt Lake City (SLC). Campus operating expenses increased 142% due to headcount expansion and new facility operations.
• Net Loss Improvement: Net loss decreased significantly by 57% compared to Q1 2024. This improvement was primarily driven by a $13.7 million reduction in the unrealized loss on warrant liabilities (from $16.2 million in Q1 2024 to $2.5 million in Q1 2025).
• Cash Flow: Net cash used in operating activities increased slightly to $5.05 million. Net cash used in investing activities was $4.50 million, primarily due to construction payments, offset by net proceeds from the sale of available-for-sale investments.

Outlook, Risks, and Management Commentary

• Construction and Development: The Company is actively developing multiple campuses (ADS, APA, DVT, OPF Phase II). Management noted that recent design defects in prototype hangars required retrofits, adding $26–$28 million in costs and 3–5 months to construction timelines for affected projects.
• Capital Requirements: The Company maintains a $166.3 million bond facility (Series 2021 Bonds) and an At-The-Market (ATM) facility with approximately $98.9 million remaining capacity. Management expects to continue incurring operating losses as it invests in construction and business development.
• Risks: Key risks include the ability to secure tenants for new facilities, rising construction costs due to inflation and tariffs (specifically on steel), and the impact of interest rate fluctuations on future borrowing costs. The Company is subject to debt covenants requiring a minimum debt service coverage ratio of 1.25.
• Recent Developments: In April 2025, the Company entered into new ground leases at Hillsboro Airport (HIO) and New York Stewart International Airport (SWF).

Investor Verification Checklist

• Warrant Liability Volatility: Verify the sensitivity of the net loss to changes in the fair value of the $48.7 million warrant liability, which caused a $2.5 million non-cash loss in Q1 2025.
• Construction Cost Overruns: Review the impact of the $26–$28 million retrofit costs on the projected completion dates and total capital requirements for the ADS, APA, and DVT projects.
• Liquidity Position: Confirm the sufficiency of the $83.65 million cash balance against the $529 million in future minimum operating lease payments and ongoing construction commitments.
• Debt Covenant Compliance: Monitor the debt service coverage ratio to ensure continued compliance with the 1.25 threshold required by the Series 2021 Bonds.
• Occupancy Rates: Track the occupancy rates of newly completed campuses (CMA, SJC) to validate revenue growth assumptions.
