## Model Purpose

This model projects Crown Castle's cash flows, Adjusted Funds From Operations (AFFO), and capital structure to determine equity valuation and dividend sustainability as the company transitions into a pure-play US tower Real Estate Investment Trust (REIT).

## Company Overview

- Crown Castle owns, operates, and leases shared communications infrastructure across the United States, providing critical real estate for wireless carriers to deploy their networks.
- Following the March 2025 agreement to sell its Fiber and Small Cell businesses, the company operates a single primary segment: Towers (representing 100% of continuing operations revenue).
- The company operates exclusively within the United States, with a significant concentration of assets in the top 100 basic trading areas.
- The business model is an asset-heavy REIT characterised by long-term customer contracts (typically 5 to 15 years) with built-in pricing escalators and high renewal rates.
- Crown Castle holds a dominant competitive position as one of the three major macro tower operators in the US, alongside American Tower and SBA Communications.
- Recent major events include the March 2025 announcement to sell the Fiber and Small Cell businesses to Zayo and EQT for $8.5 billion (expected to close in the first half of 2026), a $5.0 billion goodwill impairment charge in 2024 related to the Fiber segment, a 20% workforce reduction announced in early 2026, and a reset of the annual dividend to $4.25 per share.

## Revenue Deep Dive



### Site Rental Revenues (Towers)

- **Segment name:** Site Rental Revenues
- **Revenue driver formula:** (Beginning Tower Count x Average Tenants per Tower x Average Rent per Tenant) + Core Leasing Activity + Escalators - Non-renewals
- **Historical growth rate:** 3% to 5% organic growth historically, currently compressed due to specific customer churn events.
- **Key growth levers and headwinds:** Driven by 5G network densification and data demand. Major headwinds include the Sprint network consolidation and DISH Network contract terminations (expected to cause $240 million in churn during 2026).
- **Pricing dynamics:** Contractual, with fixed annual escalators typically around 3% or linked to inflation indices.
- **Revenue recognition notes:** Recognised on a straight-line basis over the non-cancellable lease term, which creates a variance between billed revenue and GAAP revenue.
- **Seasonality:** Minimal seasonality due to the long-term nature of the lease contracts.

### Services and Other Revenues

- **Segment name:** Services and Other Revenues
- **Revenue driver formula:** Volume of site development and installation projects x Average Project Fee
- **Historical growth rate:** Highly variable, generally tracking carrier capital expenditure cycles.
- **Key growth levers and headwinds:** Dependent on the volume of new tenant additions and equipment upgrades on existing towers.
- **Pricing dynamics:** Spot pricing based on specific project scopes and labour costs.
- **Revenue recognition notes:** Recognised over time as the services are performed.
- **Seasonality:** Can be slightly heavier in the second and third quarters due to favourable weather conditions for construction.

### Fiber and Small Cells (Discontinued Operations)

- **Segment name:** Income (Loss) from Discontinued Operations
- **Revenue driver formula:** Fixed historical run-rate until the transaction closes in mid-2026.
- **Historical growth rate:** N/A (segment is being divested).
- **Key growth levers and headwinds:** The primary driver is the timing of the transaction close, which dictates when these revenues will cease entirely.

## Cost Structure



### Variable Costs / COGS

- **Line-by-line breakdown:** Site rental costs consist primarily of ground leases, property taxes, repairs, and maintenance. Services and other costs consist of direct labour and materials for site development.
- **Gross margin range:** Site rental gross margins typically range from 70% to 75%. Services margins are much lower, typically 20% to 30%.
- **Key input costs and commodity exposures:** Ground lease expense is the largest input cost, often subject to fixed escalators.
- **How COGS scales with revenue:** High operating leverage. Adding a second or third tenant to an existing tower incurs minimal incremental operating cost, resulting in flow-through margins exceeding 90% for new leasing activity.

### Operating Expenses

- **R&D:** Not applicable for this business model.
- **SG&A:** General and administrative expenses cover corporate headcount, IT, and legal costs. The company announced a 20% workforce reduction in early 2026 to generate $65 million in annualised savings.
- **Depreciation, Amortisation, and Accretion:** Extremely high as a percentage of revenue (typically 30% to 40%) due to the capital-intensive nature of the tower portfolio.
- **Stock-Based Compensation:** Typically runs at 1% to 2% of revenue.
- **Restructuring / one-time charges:** Frequent in recent years, including advisory fees and severance costs related to the 2024 and 2026 restructuring programmes.

### Margin Profile

- **Gross margin:** Consolidated gross margin ranges from 65% to 70%.
- **Adjusted EBITDA margin:** Typically ranges from 65% to 70% of total revenues.
- **Margin trend:** Expected to expand slightly post-2026 as the lower-margin Fiber business is removed and corporate cost-cutting initiatives take effect.

## Balance Sheet Structure

- **Total assets:** Approximately $35 billion to $40 billion historically, though significantly reduced following the $5.0 billion Fiber goodwill impairment in 2024 and the reclassification of Fiber assets to "Assets held for sale".
- **Key asset categories:** Property and equipment (towers), operating lease right-of-use assets (ground leases), and intangible assets (customer contracts).
- **Goodwill & intangibles as % of total assets:** Historically over 30%, but materially lower following the 2024 impairment.
- **Working capital profile:**
  - **Days Sales Outstanding (DSO):** 20 to 30 days.
  - **Days Inventory Outstanding (DIO):** Not applicable.
  - **Days Payable Outstanding (DPO):** 30 to 45 days.
  - **Net working capital as % of revenue:** Typically negative, as deferred revenue (prepaid rent) exceeds accounts receivable.
  - **Is working capital positive or negative?** Negative, providing a slight source of cash as the business grows.
- **PP&E:** Consists of towers and related equipment. Useful lives are typically 15 to 20 years for towers.
- **Right-of-use assets / operating leases:** Highly material. The company leases the land under approximately two-thirds of its towers, resulting in billions of dollars in ROU assets and corresponding lease liabilities.

## Capital Expenditure & Investment

- **Capex as % of revenue:** For the continuing tower business, capex is very low, typically 3% to 5% of revenue.
- **Maintenance capex vs. growth capex:** Sustaining (maintenance) capex is roughly 20% of total capex, while discretionary (growth) capex makes up the remaining 80%.
- **Major capex programmes underway or planned:** Tower augmentation to support 5G equipment. The heavy capital intensity of the Fiber segment will disappear post-divestiture.
- **Capitalised software / development costs if material:** Not a material driver.
- **M&A pattern:** Historically a major acquirer, but currently in a divestiture and consolidation phase.
- **Typical acquisition multiple paid:** N/A for the current forecast period.

## Debt & Capital Structure

- **Total debt:** Approximately $20 billion to $22 billion prior to the Fiber sale.
- **Debt/EBITDA ratio:** Currently around 6.0x to 6.5x, with a target of returning to approximately 5.0x.
- **Credit rating:** Investment grade (BBB- / Baa3).
- **Key debt instruments:** Senior unsecured notes, term loans, and a revolving credit facility.
- **Maturity profile:** Well-laddered, with average maturities typically exceeding 5 years.
- **Interest rate profile:** Predominantly fixed-rate debt (over 80%), with a weighted average cost of debt around 3.5% to 4.5%.
- **Covenants:** Standard investment grade covenants, primarily limiting the ratio of total debt to adjusted EBITDA.
- **Share repurchase programme:** The company plans to initiate a $3.0 billion share repurchase programme using proceeds from the Fiber sale.
- **Dividend policy:** Reset to $4.25 per share annualised starting in Q2 2025, representing a payout ratio of approximately 75% to 80% of AFFO.

## Cash Flow Characteristics

- **Operating cash flow conversion:** Very high, with OCF frequently exceeding Net Income due to massive non-cash D&A charges.
- **Free cash flow margin:** AFFO margin (a REIT proxy for free cash flow) typically runs at 45% to 50% of site rental revenues.
- **Major non-cash items that bridge net income to OCF:** Depreciation, amortisation, straight-line revenue adjustments, and stock-based compensation.
- **Working capital cash flow impact:** Minimal impact year-over-year.
- **Capex intensity:** Drastically reduced following the Fiber divestiture, transforming the company into a high-free-cash-flow entity.
- **Cash tax rate vs. GAAP effective tax rate:** As a REIT, the company pays minimal corporate income taxes, distributing the majority of its taxable income to shareholders.

## Sheet Structure

1. **Assumptions:** Hardcoded inputs for macroeconomic drivers, segment growth, churn events, margins, capex, and capital returns.
2. **Tower Portfolio:** Roll-forward of tower count, tenants per tower, and average rent per tenant.
3. **Revenue Build:** Calculation of Site Rental Revenues (core leasing, escalators, churn) and Services Revenues.
4. **Income Statement:** GAAP P&L mirroring the 10-K, separating continuing operations from discontinued operations.
5. **Balance Sheet:** Assets, liabilities, and equity, including specific lines for ROU assets and assets/liabilities held for sale.
6. **Cash Flow Statement:** Standard indirect cash flow statement bridging Net Income to ending cash.
7. **AFFO Reconciliation:** Critical REIT schedule bridging Net Income to Adjusted EBITDA and ultimately to AFFO.
8. **Debt Schedule:** Tranche-by-tranche debt roll-forward, interest expense calculation, and mandatory repayments.
9. **Discontinued Operations:** Standalone schedule capturing the run-off of the Fiber business and the $8.5 billion transaction accounting.

## Key Financial Relationships

1. "Ending Tower Count = Beginning Tower Count + Towers Constructed + Towers Acquired - Towers Decommissioned"
2. "Site Rental Revenues = (Beginning Tower Count x Average Tenants per Tower x Average Rent per Tenant) + Core Leasing Activity + Escalators - Non-renewals"
3. "Organic Contribution to Site Rental Billings = Core Leasing Activity + Escalators - Non-renewals"
4. "Straight-Line Rent Adjustment = Cash Rent Billed - GAAP Rent Recognised"
5. "Adjusted EBITDA = Net Income + Interest Expense + Income Taxes + D&A + Impairments + Restructuring Charges - Straight-Line Revenue + Straight-Line Expense"
6. "AFFO = Adjusted EBITDA - Interest Expense - Sustaining Capex - Cash Taxes"
7. "AFFO per Share = AFFO / Diluted Shares Outstanding"
8. "Dividend Payout Ratio = Annualised Dividend per Share / AFFO per Share"
9. "Net Debt = Total Debt - Cash and Cash Equivalents"
10. "Leverage Ratio = Net Debt / Annualised Adjusted EBITDA"
11. "Discontinued Operations Cash Proceeds = $8.5 billion - Transaction Fees - Taxes"
12. "Share Repurchases = Discontinued Operations Cash Proceeds x Target Repurchase Allocation %"

## Cross-Sheet Dependencies

- The **Assumptions** sheet dictates the growth rates in the **Revenue Build** and **Tower Portfolio** sheets.
- The **Revenue Build** feeds the top line of the **Income Statement**.
- The **Income Statement** generates Net Income, which anchors the **Cash Flow Statement** and the **AFFO Reconciliation**.
- The **Discontinued Operations** sheet calculates the mid-2026 cash windfall, which flows into the **Cash Flow Statement** (investing activities) and triggers debt paydown and share buybacks in the **Debt Schedule** and **Balance Sheet**.
- Interest expense from the **Debt Schedule** flows back into the **Income Statement** and **AFFO Reconciliation**, creating a circular reference that must be managed with a toggle switch.

## Sign Convention

- Revenues, assets, and cash inflows are represented as positive numbers.
- Expenses, liabilities, and cash outflows (including capex and dividends) are represented as negative numbers in the cash flow statement and build schedules.
- In the Income Statement, expenses should be positive numbers subtracted from revenue to yield profit.
- The AFFO reconciliation should add back non-cash expenses (positive inputs) and subtract non-cash revenues (negative inputs).

## Things Most Likely to Go Wrong

- **Discontinued Operations mix-up:** Failing to isolate the Fiber business revenues and costs will severely distort the 2026 and 2027 run-rate margins for the pure-play tower business.
- **Churn cliff:** The model must explicitly account for the $240 million in DISH and Sprint churn expected in 2026; applying a generic historical growth rate will overstate revenue.
- **Straight-line rent:** GAAP revenue includes straight-line rent, but AFFO is based on billed cash rent. The model must accurately reverse straight-line revenues to calculate AFFO.
- **Share count reduction:** The $3.0 billion share repurchase programme will significantly reduce the share count in H2 2026, which is critical for calculating AFFO per share and dividend coverage.
- **Interest expense savings:** The debt paydown from the Fiber sale proceeds will reduce interest expense by an estimated $120 million annualised; the debt schedule must capture this dynamic.
- **Workforce reduction timing:** The $65 million in annualised SG&A savings from the 2026 restructuring will only partially benefit 2026 and will fully materialise in 2027.
- **REIT tax status:** Applying a standard corporate tax rate will break the model. Cash taxes are negligible.
- **Capital expenditure drop:** Sustaining capex will plummet once the Fiber business is removed; historical consolidated capex ratios are useless for the forecast period.

## Validation Checks

- "AFFO per share must comfortably cover the $4.25 annualised dividend (payout ratio should be 75% to 80%)."
- "Consolidated Adjusted EBITDA margin should expand to approximately 70% following the divestiture of the lower-margin Fiber segment."
- "Total debt should decrease by the exact amount of Fiber sale proceeds allocated to debt repayment."
- "Sustaining capex should not exceed $40 million to $50 million annually for the pure-play tower business."
- "The balance sheet must balance in every period: Total Assets = Total Liabilities + Equity."
- "Organic site rental growth should dip to approximately 3.3% in 2026 due to churn, before recovering in 2027."
- "Share count must decrease in 2026 commensurate with the $3.0 billion repurchase programme divided by the prevailing share price."
