What is the difference between static and digital billboards?

Static billboards display a single advertiser's vinyl message swapped every 4-12 weeks. Digital LED billboards cycle 8 advertisers @ 8 seconds (64-second loop), generating 4-8x more revenue per face than static — at 5-10x the CapEx. Digital conversion is the major industry trend; LAMR and OUT have converted 5-10% of inventory to digital, with material capital deployment programs ongoing. Local zoning often restricts digital LED conversion + brightness; conversion typically requires re-permitting. Geopath impressions per face are similar between static + digital, but digital sells at higher CPM due to creative-rotation flexibility.

Which REITs own billboards?

Lamar Advertising (LAMR, ~$13B mkt cap, ~350,000 displays in US + Canada, primarily highway-corridor focused) and OUTFRONT Media (OUT, ~$3B mkt cap, ~500,000 US displays + extensive transit advertising including NYC subway + LA Metro) are the two pure-play OOH REITs. Both elected REIT status in 2014 (OUT) and 2014 (LAMR) under the IRS REIT structure for billboards. Clear Channel Outdoor (CCO, ~$1B mkt cap) is structured as an operating company rather than a REIT — owns major US + international portfolio.

How does the Highway Beautification Act limit billboard supply?

The Highway Beautification Act of 1965 (HBA) requires states to control billboard placement along Federal Aid Primary + Interstate highways through state-level laws "compatible" with federal restrictions (size limits, spacing requirements, height limits, lighting). States with OAAA-compatible laws have grandfathered existing structures while severely restricting new construction. The result: existing highway billboards have substantial scarcity value — new permits are rarely issued, and grandfathered structures trade at meaningful premiums to construction cost. The HBA + state restrictions effectively cap public-REIT OOH supply growth, supporting pricing power + cap rate compression on existing inventory.

Billboard KPIs.

Billboards are out-of-home (OOH) advertising structures — static vinyl billboards, digital LED billboards, transit advertising (bus + rail), street furniture, and place-based digital displays. Performance is measured in audited audience impressions (DMA-level OOH impressions per face), sell-through rate (% of available faces sold), CPM (cost per thousand impressions, typically $5-$25 OOH vs $25-$100 digital programmatic), occupancy %, and rate-card discount (street rate vs published rate). The category is dominated by two pure-play public REITs: LAMR (Lamar Advertising — 350,000+ displays in US/Canada) and OUT (OUTFRONT Media — 500,000+ US displays + transit). Clear Channel Outdoor (CCO) is a non-REIT operating company. Digital LED conversion is the major industry trend — digital boards yield 4-8x revenue of static at 5-10x CapEx. The Highway Beautification Act of 1965 + state OAAA-compatible laws cap new billboard supply on Federal Aid Primary highways, creating scarcity value for grandfathered locations. Ilora.ai ingests OOH structure inventory, sell-through reports, audited OOH ratings (Geopath impressions), digital conversion CapEx flow, and ground-lease + permit schedules, then benchmarks against LAMR + OUT comparables.

NOI: Total revenue minus operating expenses (excludes financing and capital costs). The primary measure of property-level profitability.
Cap Rate: Net Operating Income divided by current property value. Expresses unleveraged annual yield as a percentage.
DSCR: Net Operating Income divided by total annual debt service. Lender-required cushion measure; below 1.0 means NOI cannot cover debt.
LTV: Loan amount divided by property value. Lower LTV = lower lender risk.
OER: Operating expenses divided by gross revenue. Lower is better, but varies by property type (hotels run higher than triple-net retail).
GRM: Property value divided by gross annual rental income. Quick valuation shortcut; less precise than cap rate.
IRR: Annualized return on investment accounting for time value of money across the full hold period.
CoC: Pre-tax annual cash flow divided by total cash invested. Measures the cash yield, not total return.
DCF: Valuation method that projects future cash flows and discounts them to present value at a chosen rate.
TTM: A rolling sum of the most recent 12 months. Smooths seasonality for KPI comparisons.
Tenants: Number of carriers leasing on a single cell tower. Each additional tenant is high-margin incremental revenue.
CF: Actual energy generated divided by theoretical maximum. Solar farm productivity measure.
