# Analyzing Digital Infrastructure Assets

## When To Use

- Evaluating a data center acquisition or development financing (single-site or portfolio)
- Analyzing a wireless tower portfolio for purchase, sale, or lease-up valuation
- Assessing fiber network assets (lit or dark fiber) for infrastructure fund deployment
- Conducting due diligence on colocation, hyperscale, or edge data center investments
- Reviewing digital infrastructure assets within a broader PPP or project finance structure

## Inputs To Gather

- **Asset inventory**: Site addresses, facility types (tower/data center/fiber route), owned vs. leased land, build year, and remaining useful life estimates
- **Capacity and utilization data**: Total MW/rack capacity vs. current load (data centers), available tenancy slots vs. occupied (towers), lit vs. dark fiber strand counts
- **Tenant and revenue detail**: Tenant roster with contract terms, escalation schedules, renewal options, and credit ratings; revenue concentration by tenant
- **Capital expenditure history and projections**: Maintenance capex, expansion capex, technology refresh cycles, and deferred maintenance backlog
- **Operating metrics**: Power Usage Effectiveness (PUE) for data centers, average revenue per tower (ARPT), fiber route miles and density metrics
- **Regulatory and permitting status**: Zoning, FCC/FAA compliance (towers), local power and water entitlements (data centers), right-of-way agreements (fiber) [VERIFY jurisdiction-specific requirements]
- **Debt and financing terms**: Existing securitization structures (e.g., tower ABS), project-level debt covenants, DSCR requirements

## Workflow

1. **Classify asset type and scope** — Determine whether the analysis covers towers, data centers, fiber, or a mixed portfolio. Identify the investment thesis (yield play, growth/lease-up, development) as this drives which metrics matter most.

2. **Analyze physical capacity and utilization**
   - Data centers: Calculate current vs. total MW capacity, rack density, cooling headroom, and PUE trends. Flag facilities above 85% utilization as capacity-constrained.
   - Towers: Count tenancy ratio (tenants per tower), identify co-location capacity remaining, and assess ground space for additional equipment.
   - Fiber: Map lit vs. dark strand utilization, route redundancy, and proximity to demand anchors (enterprise campuses, wireless towers, data centers).

3. **Evaluate tenant credit and revenue quality**
   - Build a tenant concentration table: top 5 tenants by revenue share, weighted-average remaining lease term (WALT), and credit ratings.
   - Flag single-tenant concentration above 25% of revenue or any tenant below investment-grade credit.
   - Assess contractual escalators (CPI-linked vs. fixed) and mark-to-market opportunity on below-market leases.

4. **Assess technology obsolescence risk**
   - Towers: Evaluate 5G densification impact — will small-cell deployments reduce macro tower demand, or drive amendment revenue? Assess carrier consolidation risk. [VERIFY current carrier M&A landscape]
   - Data centers: Review power and cooling architecture against current hyperscaler requirements. Facilities built pre-2015 with air-cooled designs may require significant retrofit for AI/ML workload density.
   - Fiber: Assess whether existing fiber plant supports current wavelength standards; evaluate competitive overbuild risk in the service area.

5. **Model cash flows and valuation**
   - Build a 10-year discounted cash flow with explicit assumptions for: tenant churn, new lease-up pace, escalators, capex, and terminal value.
   - Apply sector-appropriate cap rates: towers (low-to-mid single digits), data centers (mid-single digits, varies by tier), fiber (varies by lit vs. dark economics). [VERIFY current market cap rates]
   - Stress-test for: 20% tenant churn scenario, power cost escalation (data centers), interest rate sensitivity on leveraged returns.

6. **Identify structural and regulatory risks**
   - Review ground lease terms for towers (remaining term, renewal risk, rent escalation).
   - Assess power and water availability and long-term pricing for data centers, especially in constrained markets.
   - Evaluate right-of-way renewal risk and municipal franchise requirements for fiber. [VERIFY local franchise/ROW renewal terms]

## Output

Structure the analysis report with the following sections:

- **Executive Summary**: Asset type, investment thesis, headline valuation range, and top 3 risks
- **Asset Overview**: Inventory table with key physical attributes and geographic distribution
- **Capacity and Utilization Analysis**: Current utilization, expansion runway, and capacity constraints
- **Tenant and Revenue Analysis**: Concentration table, WALT, credit quality summary, and escalator profile
- **Technology Obsolescence Assessment**: Risk rating (low/medium/high) per asset class with supporting rationale
- **Financial Model Summary**: Base case IRR/MOIC, key assumptions table, and sensitivity analysis output
- **Risk Matrix**: Ranked risks with likelihood, impact, and proposed mitigants
- **Appendix**: Detailed assumptions, data sources, and items marked [VERIFY]

## Quality Checks

- Confirm that utilization metrics are sourced from operator-provided data, not estimates; flag any interpolated figures
- Verify that tenant credit ratings are current (within 12 months) and sourced from recognized agencies
- Ensure cap rates and discount rates reflect the specific asset sub-type, not generic "digital infrastructure" benchmarks
- Check that technology obsolescence assessment references specific technical standards (e.g., power density per rack in kW, fiber wavelength capacity) rather than vague trend commentary
- Validate that the DCF model ties to the tenant-by-tenant revenue build-up, not a top-down growth assumption
- Confirm all jurisdiction-dependent items (zoning, FCC/FAA, ROW, franchise) are marked [VERIFY] with the relevant authority identified
