This section explores key financing mechanisms for datacenter and AI infrastructure projects, focusing on options like corporate capex, debt/equity, project finance, and sale-leasebacks. It highlights implications for Crown Castle financing strategies, including asset-light approaches, with examples from industry precedents.

Financing datacenter infrastructure requires balancing high upfront capital expenditures (capex) with long-term revenue stability from leases. In Crown Castle markets, where tower and fiber assets intersect with growing AI demands, structures like project finance and sale-leasebacks enable scalable growth. Corporate capex funds developments on-balance-sheet, while debt/equity mixes leverage institutional capital. Project finance isolates risks via non-recourse debt, and sale-leasebacks provide liquidity without full asset disposal. Typical datacenter project debt features loan-to-value (LTV) ratios of 60-70%, debt service coverage ratios (DSCR) of 1.5-2.0x, tenors of 15-20 years, and spreads of 200-350 basis points over benchmarks, per Moody’s and S&P analyses. Yield spreads on datacenter corporate bonds range from 150-250 bps, as seen in Digital Realty issuances. Green/ESG-linked financing can reduce costs by 10-25 bps through sustainability premiums, aligning with Crown Castle’s ESG goals.

For Crown Castle, asset-light strategies favor sale-leasebacks to monetize assets without heavy capex, preserving balance sheet flexibility. Asset-heavy approaches suit project finance for owned developments. Sustainability-linked instruments lower the cost of capital by tying rates to ESG performance, potentially saving 0.5-1% on interest. However, long-term leasebacks carry covenant risks like rent coverage tests and refinancing exposure every 5-10 years, especially if cap rates rise.

Crown Castle financing disclosures show a mix of these, with recent deals emphasizing hybrid structures to optimize leverage.
