INVESTMENT STRATEGY

21

Investment Strategy: Underwriting ApproachReal estate focused / Motivated to exceed long-term cost of capital

• Property attributes – Quality of real estate, age, size, fungibility

• Market review – Strategic locations critical to generating revenue

• Demographic analysis – Five-mile population density, household income, unemployment trends

• Valuation – Replacement cost, market rents, initial cash yield, IRR over initial lease term

• Property due diligence – Site visits, vehicle traffic, industry, property type, title, environmental, etc.

REAL ESTATE ANALYSIS

CREDIT ANALYSIS

• Financial review and analysis

• Tenant research – Reliable, sustainable cash flow

• Industry research – Defensive, resilient to macroeconomic volatility

• Discussion with key management representatives

Strong unit-level cash flow coverage (specific to each industry)

Tenants with service, non-discretionary, and/or low pricepoint component to their business

Favorable sales and demographic trends

Significant markets (generally MSAs of ≥350,000 people) and/or mission critical locations

Primarily industrial and distribution properties leased to Fortune 1000, investment grade rated tenants

Scalability of Costs Contributes to Higher Relative Valuation

• Efficiency and scalability of business model leads net lease industry

• G&A expense should be treated the same as dollar of property-level cash flow

• Consensus NAV estimates generally exclude impact of G&A expenses, thus no explicit “credit” for G&A efficiencies is recognized

• Capping G&A with real estate multiple degrades NAV/sh more for smaller portfolios with less scalability
