### SBA Communications Corporation (SBAC) — Business Overview

#### Business Description
SBA Communications is a leading independent owner and operator of wireless communications tower infrastructure, structured as a REIT. Founded in 1989 and headquartered in Boca Raton, Florida, the company leases space on its 46,328 towers to wireless carriers under long-term contracts with annual rent escalators. Approximately 97.9% of segment operating profit comes from site leasing — making SBAC one of the purest tower infrastructure plays in the market. The company operates primarily in the U.S. (72.6% of site leasing revenue) and select international markets, having recently exited Canada, Philippines, and Colombia to focus capital on higher-growth regions.

#### Revenue Model
SBA Communications generates revenue almost entirely from multi-tenant tower leases. Carriers pay recurring monthly rents to co-locate antennas and related equipment on SBA's tower structures. Lease terms typically run 5–10 years with 3–4% annual rent escalators, creating highly predictable, inflation-linked cash flow streams. A second, smaller segment — Site Development — provides network build-out services (site acquisition, zoning, construction) to carriers building new towers, generating modest project-based revenue (~2% of operating profit). Tower leases are essentially fixed-cost infrastructure with incremental margins above 90% when additional tenants are added.

#### Products & Services

**Site Leasing (~98% of operating profit):**
- Multi-tenant tower leasing (macro towers, rooftop installations)
- Distributed Antenna Systems (DAS) and small cells
- Long-term lease agreements with built-in CPI or fixed annual escalators
- New tower builds for carrier customers (build-to-suit)

**Site Development (~2% of operating profit):**
- Site acquisition and zoning services
- Tower construction and equipment installation
- Network build-out project management for MNOs

#### Customer Base & Go-to-Market
SBA Communications' three largest customers — T-Mobile, AT&T, and Verizon — accounted for 66.5% of total revenues in 2025 (T-Mobile alone ~35%). Revenue concentration among the major U.S. carriers creates both durable relationships and meaningful tenant risk. International exposure (~27% of revenue) spans Brazil, Central America (expanded through the 7,000-tower Millicom/TIGO acquisition), and other Latin American markets. Customer churn is primarily driven by carrier M&A (Sprint/T-Mobile consolidation) and financial distress (EchoStar/DISH default).

#### Competitive Position
SBAC is the third-largest U.S. tower REIT behind American Tower and Crown Castle, competing in a rational oligopoly where infrastructure sharing reduces carrier costs and creates high barriers to entry. Tower building requires years of permitting, community negotiation, and significant upfront capital — giving existing owners a structural moat. With 80% Tower Cash Flow margins and escalating rents, SBA generates superior cash yields on invested capital. The company has been the most aggressive in international expansion among the big three, with ~27% of revenue from international markets (vs. AMT's ~50% and CCI's ~0%).

#### Key Facts
- Founded: 1989
- Headquarters: Boca Raton, Florida
- Employees: ~1,600
- Exchange: NASDAQ
- Sector / Industry: Real Estate / Specialized REITs (Tower Infrastructure)
- Towers: ~46,300 globally (17,400 U.S. + 28,900 international)

### SBA Communications Corporation (SBAC) — Investment Catalysts & Risks

#### Bull Case Drivers

1. **Churn Peak Behind Us — Organic Growth Inflection Ahead** — The $51M Sprint/T-Mobile merger churn and $56M EchoStar/DISH default headwinds are expected to "significantly step down" by 2026, resetting SBA's organic growth profile. Once these non-recurring churn events clear, the underlying lease-up rate (new tenants on existing towers) and contractual 3–4% annual rent escalators should drive AFFO per share acceleration to high single digits. The Millicom/TIGO acquisition of 7,000 Central American towers adds a new international growth engine in markets with low tower tenancy ratios, providing a multi-year build-out opportunity.

2. **5G Densification and Fixed Wireless Access Drive Lease-Up** — U.S. carriers are mid-cycle in deploying mid-band 5G spectrum (C-band, CBRS), which requires denser network coverage and more tower antennas per site. Each spectrum layer added per carrier generates additional lease amendments, driving incremental revenue on existing towers with near-100% incremental margin. Fixed wireless access (FWA) growth by T-Mobile and Verizon, plus satellite operators seeking terrestrial anchor points, are adding new demand vectors. Analysts project U.S. organic growth recovering to 4–5% once legacy churn normalizes.

3. **Path to Investment Grade Unlocks Valuation Re-Rating** — SBAC currently operates with ~6.1x net debt/EBITDA leverage, above investment-grade thresholds. Management has explicitly targeted achieving investment-grade credit ratings by 2026 through debt paydown and EBITDA growth. Achievement would lower the cost of capital, open access to a broader set of bond investors, and likely prompt a valuation re-rating. A 13% dividend increase signals management confidence in this path. Consensus analyst target of $234.53 implies ~8% upside from current levels, with bull-case targets exceeding $280.

#### Bear Case Risks

1. **Elevated Leverage and Refinancing Exposure** — Net debt of $12.0B at 6.1x EBITDA is high for a REIT and leaves limited margin for error. Rising interest rates increase refinancing costs on floating-rate debt and near-term maturities. If EBITDA growth disappoints due to extended carrier churn or international market deterioration, leverage metrics could worsen, constraining the dividend growth story and delaying the investment-grade path. Wells Fargo reduced its target to $195 from $205, citing 2026 expense pressure.

2. **Customer Concentration and Carrier Consolidation Risk** — Three customers (T-Mobile, AT&T, Verizon) account for 66.5% of revenue, making SBA acutely exposed to any of their strategic pivots — network sharing agreements, spectrum refarming that reduces tower count, or financial distress. The EchoStar/DISH default demonstrates that even sizeable contracts can collapse quickly. Another round of U.S. carrier consolidation (hypothetically AT&T + T-Mobile) would trigger a second wave of churn that the market is not pricing in.

3. **International Execution Risk and Currency Headwinds** — With ~27% of revenue from Latin American and other international markets, SBA faces meaningful currency translation risk (Brazilian Real, Colombian Peso historically volatile), sovereign regulatory risk, and local carrier consolidation events. The exit from Canada, Philippines, and Colombia reflects that international markets can deteriorate faster than expected. The Millicom/TIGO acquisition adds 7,000 towers in markets with lower per-capita incomes and less mature wireless penetration — execution risk is real if those markets don't develop as projected.

#### Upcoming Events
- **Q2 2026 Earnings (July 2026)**: Key test of whether Sprint/EchoStar churn is indeed "stepping down" and whether organic leasing momentum is accelerating
- **Investment-Grade Rating Achievement (expected 2026)**: Potential catalyst for valuation re-rating if S&P/Moody's upgrade occurs
- **Millicom/TIGO Integration**: First full year of Central American portfolio contribution — lease-up rate data will validate acquisition thesis

#### Analyst Sentiment
Average analyst rating: Buy, with a consensus 12-month price target of $234.53 (~8% upside). Wells Fargo (Equal Weight, $195) and JPMorgan/Bernstein (Neutral) are cautious, citing 2026 expense pressure and the need for clearer organic growth inflection. Bulls argue SBAC is in a classic "trough to turn" setup where the churn headwinds are well-understood and the re-acceleration is underappreciated.
