## Model Purpose

This model forecasts Net Asset Value (NAV) and Adjusted Funds From Operations (AFFO) to determine equity valuation and dividend sustainability for Public Storage (PSA), enabling an equity analyst to assess the REIT's total return potential amid fluctuating self-storage demand and interest rate cycles.

## Company Overview

Public Storage is a self-storage real estate investment trust (REIT) that acquires, develops, owns, and operates self-storage facilities. It is the largest operator of self-storage facilities in the world, managing over 3,380 properties and approximately 245 million rentable square feet across the United States and Europe (via its stake in Shurgard).
- **Business Segments**: Self-Storage Operations (~94% of revenue) and Ancillary Operations (~6% of revenue, primarily tenant insurance).
- **Key Geographies**: Highly concentrated in the United States (major MSAs in California, Texas, Florida, and the Mid-Atlantic), with European exposure through an equity investment in Shurgard Self Storage.
- **Business Model Type**: Asset-heavy real estate owner/operator with a highly fragmented, short-term lease (month-to-month) customer base.
- **Competitive Position**: The undisputed market leader in the US self-storage industry, benefiting from massive scale, a proprietary digital platform (PS 4.0), and the lowest cost of capital among peers.
- **Recent Major Events**: Acquired Simply Self Storage for $2.2 billion in 2023; acquired 87 facilities for $945.6 million in 2025; announced a CEO transition from Joe Russell to Tom Boyle effective April 2026.

## Revenue Deep Dive



### Self-Storage Operations

- **Segment Name**: Self-Storage Revenues
- **Revenue Driver Formula**: Total Rentable Square Feet x Average Occupancy % x Realised Annualised Rent per Occupied Square Foot.
- **Historical Growth Rate**: 2-5% CAGR (recently negative in 2025 at -0.2% same-store revenue growth due to industry normalization).
- **Key Growth Levers and Headwinds**: Levers include digital pricing algorithms, facility expansions, and acquisitions. Headwinds include housing market stagnation (fewer people moving), increased local supply, and competitive discounting on move-in rates.
- **Pricing Dynamics**: Month-to-month leases allow for rapid repricing. The company frequently offers promotional "move-in" rates and aggressively raises rents on existing tenants (in-place rent vs. street rent dynamic).
- **Revenue Recognition Notes**: Recognised ratably over the lease term. Rent is typically collected in advance, creating deferred revenue liabilities.
- **Seasonality**: Q2 and Q3 are historically the strongest quarters, aligning with the summer moving season and university schedules.

### Ancillary Operations

- **Segment Name**: Ancillary Revenues
- **Revenue Driver Formula**: Total Tenants x Insurance Penetration Rate x Average Monthly Premium + Merchandise Sales.
- **Historical Growth Rate**: 4-7% CAGR.
- **Key Growth Levers and Headwinds**: Driven by the Orange Door Storage Insurance Program. Highly profitable but scales linearly with occupancy.
- **Pricing Dynamics**: Regulated insurance premiums, generally sticky and price-inelastic for the consumer.
- **Revenue Recognition Notes**: Insurance premiums recognised over the policy period.
- **Seasonality**: Mirrors self-storage occupancy seasonality.

## Cost Structure



### Variable Costs / COGS (Property Operating Expenses)

- **Line-by-line breakdown**: On-site property manager payroll, property taxes, utilities, repairs and maintenance, and marketing.
- **Gross Margin (NOI Margin) Range**: 75% - 79% (Q4 2025 Same-Store NOI margin was 78.4%).
- **Key input costs**: Property taxes are the largest single expense and are subject to reassessment upon property acquisition or local municipal rate hikes.
- **How COGS scales**: High operating leverage. Once a facility covers its fixed property taxes and basic staffing, incremental rental revenue drops almost entirely to the bottom line.

### Operating Expenses

- **R&D**: N/A for this REIT.
- **SG&A**: General and administrative expenses, including corporate payroll, legal, and technology investments (PS 4.0 digital ecosystem).
- **Depreciation & Amortisation**: Massive non-cash expense representing 20-25% of revenue, driven by the real estate portfolio. Added back for FFO calculations.
- **Stock-Based Compensation**: Minimal relative to revenue, but must be tracked for AFFO adjustments.
- **Restructuring / one-time charges**: Infrequent, occasionally related to natural disaster damages (e.g., Los Angeles fires).

### Margin Profile

- **NOI Margin**: 75-79%.
- **EBITDA Margin**: 65-70%.
- **Net Margin**: 35-45% (heavily distorted by real estate depreciation).
- **Margin trend**: Slightly compressing in 2025/2026 due to sticky property tax inflation and flat/negative rent growth, though PSA maintains the highest margins in the peer group.

## Balance Sheet Structure

- **Total assets**: ~$25-30 billion (book value, significantly understates market value of real estate).
- **Key asset categories**: Real Estate Facilities (at cost), Accumulated Depreciation, Investments in Real Estate Entities (Shurgard).
- **Goodwill & intangibles**: Minimal; real estate acquisitions are primarily allocated to tangible land and building assets.
- **Working capital profile**:
  - **DSO**: < 5 days (rent is paid in advance).
  - **DIO**: N/A.
  - **DPO**: 15-30 days.
  - **Net working capital**: Structurally negative. Tenants pay upfront (deferred revenue), providing a continuous float to fund operations.
- **PP&E**: Represents the core self-storage portfolio. Land is not depreciated; buildings are depreciated over 25-30 years.
- **Right-of-use assets**: Immaterial; PSA owns the vast majority of its real estate fee-simple.

## Capital Expenditure & Investment

- **Capex as % of revenue**: 10-15% (heavily skewed toward growth/acquisitions rather than maintenance).
- **Maintenance capex vs. growth capex**: Maintenance capex is very low (roofs, doors, HVAC). Growth capex (development and redevelopment) is substantial, with a $609.9 million pipeline expected over 2026-2027.
- **Major capex programmes**: "Property of Tomorrow" rebranding initiative ($600M multi-year investment) and multi-story premium storage conversions.
- **Capitalised software**: Investments in the PS 4.0 digital platform are capitalised but represent a small fraction of total assets.
- **M&A pattern**: Serial acquirer. Mix of bolt-on single assets and transformational portfolio deals (e.g., Simply Self Storage).
- **Typical acquisition multiple**: Historically 4.5% - 6.0% cap rates depending on market conditions.

## Debt & Capital Structure

- **Total debt**: $10.3 billion as of December 31, 2025.
- **Debt/EBITDA ratio**: Net Debt and Preferred Equity to EBITDA is 4.2x (Q4 2025).
- **Credit rating**: A2 (Moody's) / A (S&P).
- **Key debt instruments**: Unsecured senior notes, term loans, and a revolving credit facility.
- **Preferred Equity**: PSA is unique among REITs for its heavy reliance on perpetual preferred stock as a core funding vehicle (often $4-5 billion outstanding).
- **Maturity profile**: $1.15 billion maturing in 2026; weighted average term of 6.3 years.
- **Interest rate profile**: Weighted average interest rate of 3.2% (largely fixed-rate debt).
- **Covenants**: Standard REIT unsecured debt covenants (total debt to total assets < 60-65%).
- **Share repurchase programme**: Rarely active; capital is prioritized for acquisitions and dividends.
- **Dividend policy**: High payout ratio mandated by REIT rules. Annual dividend is a primary driver of shareholder return.

## Cash Flow Characteristics

- **Operating cash flow conversion**: Extremely high. OCF often exceeds Net Income due to massive non-cash depreciation add-backs.
- **Free cash flow margin**: AFFO margin typically exceeds 50%.
- **Major non-cash items**: Real estate depreciation and amortisation.
- **Working capital cash flow impact**: Favourable source of cash due to deferred revenue growth as the portfolio expands.
- **Capex intensity**: Low maintenance capex intensity; high growth capex intensity.
- **Cash tax rate**: Near 0%. As a REIT, PSA pays no federal income tax on earnings distributed to shareholders.

## Sheet Structure

1. **Assumptions**: Hardcoded drivers for macro (interest rates), portfolio growth (acquisitions, developments), and operating metrics (occupancy, rent per sq ft).
2. **Portfolio Roll-Forward**: Tracks Beginning Sq Ft, Acquired Sq Ft, Developed Sq Ft, and Ending Sq Ft. Calculates average occupied square feet.
3. **Same-Store vs. Non-Same-Store**: Splits the portfolio to project Same-Store Revenue, Same-Store Expenses, and Same-Store NOI, plus the Non-Same-Store contribution.
4. **Income Statement**: Consolidated GAAP view. Self-Storage Revenues, Ancillary Revenues, Property Operations, Depreciation, G&A, Interest Expense, Net Income.
5. **Balance Sheet**: Real Estate at Cost, Accumulated Depreciation, Cash, Debt, Preferred Equity, Common Equity.
6. **Cash Flow Statement**: GAAP cash flow bridging Net Income to OCF, ICF (acquisitions/capex), and FCF (debt issuance, dividends).
7. **FFO & AFFO Build**: Net Income less Preferred Dividends + Real Estate Depreciation = FFO. FFO less Maintenance Capex = AFFO.
8. **Debt & Preferred Schedule**: Tranches of unsecured notes, preferred stock series, interest rate calculations, and maturity wall.
9. **NAV Valuation**: Applies a market capitalization rate to forward 12-month NOI, adds cash, subtracts debt and preferred equity to arrive at Net Asset Value per share.
10. **DCF / Dividend Discount Model**: 10-year forecast of AFFO per share and dividends, discounted at the cost of equity.

## Key Financial Relationships

1. `Ending Rentable Sq Ft = Beginning Rentable Sq Ft + Acquired Sq Ft + Developed Sq Ft - Disposed Sq Ft`
2. `Average Occupied Sq Ft = (Beginning Rentable Sq Ft + Ending Rentable Sq Ft) / 2 * Average Occupancy %`
3. `Self-Storage Revenue = Average Occupied Sq Ft * Annualised Realised Rent per Sq Ft`
4. `Ancillary Revenue = Average Occupied Units * Insurance Penetration % * Annual Premium per Policy`
5. `Total Property Operating Expenses = Same-Store Expenses + Non-Same-Store Expenses`
6. `Net Operating Income (NOI) = Self-Storage Revenue + Ancillary Revenue - Total Property Operating Expenses`
7. `NOI Margin = Net Operating Income / Total Revenues`
8. `GAAP Net Income = NOI - Depreciation & Amortisation - G&A - Interest Expense + Equity in Earnings of Shurgard`
9. `Net Income Attributable to Common = GAAP Net Income - Preferred Stock Dividends - Noncontrolling Interests`
10. `Funds From Operations (FFO) = Net Income Attributable to Common + Real Estate Depreciation & Amortisation - Gains on Sale of Real Estate`
11. `Adjusted FFO (AFFO) = FFO - Maintenance Capex - Non-Cash Stock Compensation`
12. `Net Debt & Preferred to EBITDA = (Total Debt + Preferred Equity - Cash) / Annualised EBITDA`
13. `Implied Capitalisation Rate = Forward 12M NOI / Implied Total Enterprise Value`
14. `Net Asset Value (NAV) = (Forward 12M NOI / Market Cap Rate) + Cash + Investments in Shurgard - Total Debt - Preferred Equity`

## Cross-Sheet Dependencies

- The **Portfolio Roll-Forward** dictates the square footage used in the **Same-Store vs. Non-Same-Store** sheet to calculate revenues and property expenses.
- The **Same-Store vs. Non-Same-Store** sheet aggregates to total NOI, which feeds the top half of the **Income Statement**.
- The **Debt & Preferred Schedule** calculates interest expense and preferred dividends, which feed the **Income Statement** and **FFO & AFFO Build**.
- The **Income Statement** generates Net Income, which is the starting point for the **Cash Flow Statement** and **FFO & AFFO Build**.
- The **Cash Flow Statement** determines the ending cash balance and debt funding requirements, creating a potential circularity with the **Debt & Preferred Schedule** if revolving credit facility interest is tied to average debt balances.

## Sign Convention

- **Revenues and Assets**: Entered and displayed as positive numbers.
- **Expenses and Liabilities**: Entered as positive numbers in their specific build schedules (e.g., Property Taxes = 500), but subtracted in aggregation formulas (e.g., `Revenue - Expenses`).
- **Cash Flow**: Inflows are positive, outflows (capex, dividends, debt repayment) are negative.
- **Contra-Assets**: Accumulated Depreciation is displayed as a negative number on the Balance Sheet.

## Things Most Likely to Go Wrong

- **Ignoring Preferred Equity**: PSA uses billions in preferred stock. Failing to deduct preferred dividends from Net Income before calculating FFO per share will drastically overstate equity value.
- **Confusing Same-Store and Total Metrics**: Same-store pools are fixed at the start of the year. Growth rates applied to the total portfolio instead of the same-store pool will double-count acquisition growth.
- **Underestimating Property Taxes**: When PSA acquires a facility, the property is often reassessed at the purchase price, causing a massive step-up in property taxes that compresses the acquired facility's NOI margin.
- **Capital Expenditure Misclassification**: Deducting growth/development capex in the AFFO calculation instead of just maintenance capex will artificially crush the company's cash flow profile.
- **Straight-Line Rent Adjustments**: While less volatile than office REITs, failing to adjust for straight-line rent in the AFFO build can cause slight cash flow mismatches.
- **Shurgard Equity Income**: PSA owns ~35% of Shurgard Europe. This equity income must be included in FFO but excluded from consolidated NOI.
- **Interest Rate Mismatch**: Assuming floating rates for the entire debt stack. PSA's debt is largely fixed (3.2% weighted average); modeling it as floating will overstate interest expense in a high-rate environment.
- **Share Count Dilution**: Using basic shares instead of fully diluted shares (including OP units) will overstate per-share FFO and NAV.

## Validation Checks

- "NOI Margin should be in the 75-79% range; flag if outside this band."
- "Average Occupancy should remain between 92% and 95% based on historical stabilization levels."
- "Net Debt + Preferred Equity to EBITDA should remain near 4.0x (currently 4.2x); flag if it exceeds 5.0x."
- "Maintenance Capex should be roughly $0.50 to $1.00 per square foot annually."
- "FFO Payout Ratio (Dividends / FFO) should be between 70% and 85% to maintain REIT compliance while retaining some cash."
- "Balance sheet must balance: Total Assets = Total Liabilities + Preferred Equity + Common Equity in every period."
- "Weighted average interest rate should remain near 3.2% in the near term due to the fixed-rate debt profile."
- "Core FFO per share for 2026 should align with management guidance of $16.35 to $17.00."
