Analyst Note: SBAC (SBA Communications Corporation)

Date: 2026-06-20 Current Price: $186.87

1. Structural Readiness

• State: Forming
• Conservative Entry: Not yet triggered (awaiting confirmed breakout above the coil resistance).
• Aggressive/Pre-Breakout Entry: Not actionable on setup alone; currently a partial readiness signal.
• Breakout Level: Pending confirmation.
• Current Price: $186.87.
• Extension: Not applicable (price is within the consolidation range, not extended above the breakout).
• ATR Context: Current ATR is 3.4% (productive). This sits within the historical "sweet spot" (4–6% is ideal, but 3.4% indicates manageable volatility for sizing, well below the "extreme" >8% risk zone).

2. Thesis Layer

• Thesis Status: TACTICAL / SETUP-LED.
• Macro Thesis: There is NO named secular thesis attached to this specific setup at this date.
• Judgment Criteria: The investment case must be judged strictly on the quality of the structural setup (the forming coil) and the immediate business fundamentals provided in the evidence. Do not invent a macro narrative; rely on the "Margin Inflector" archetype and the specific operational data available as of June 20, 2026.

3. Business Overview

SBA Communications Corporation operates as a tower infrastructure provider, deriving 98.5% of its total segment operating profit from its site leasing business (Evidence E9). The company leases antenna space on towers to wireless service providers, primarily T-Mobile, AT&T Wireless, and Verizon Wireless in the U.S. (Evidence E10, E17).

Key Operational Data as of June 20, 2026:

• Revenue Growth: Management increased full-year 2026 outlook for site leasing revenue, cash flow, adjusted EBITDA, and AFFO per share, citing a "solid start of the year" (Evidence E1).
• New Billings: In Q1 2026, the U.S. added approximately $10 million in quarterly new lease and amendment billings year-over-year, while international markets added approximately $4 million (Evidence E2, E3).
• Growth Drivers: U.S. growth is fueled by carrier investment in 5G coverage (C-band spectrum), massive MIMO upgrades, and Fixed Wireless Access (FWA) expansion (Evidence E5).
• International Strategy: The company is integrating Millicom assets, seeing colocation demand exceed initial projections (Evidence E7). They hold a leading position in Central America, which is expected to reduce FX exposure and extend lease terms (Evidence E8).
• Churn Management: Management expects 2026 to be the "peak year" for international churn, with an expectation of improvement in churn rates over the subsequent years (Evidence E4).
• Domestic Churn Expectation: $132.0M – $136.0M for 2026, driven by Sprint and EchoStar (Evidence E12).
• International Churn Expectation: $36.0M – $40.0M for 2026, driven by Oi wireline churn (Evidence E13).
• Acquisitions: As of the filing date (May 5, 2026), the company had purchased or contracted to purchase 56 sites for $36.9 million, with closing anticipated by Q3 2026 (Evidence E14).
• Asset Base: As of Dec 31, 2025, the company owned 46,328 towers. 71% of these structures are on land owned or controlled for >20 years, with an average remaining lease life of 35 years (Evidence E21, E23).

4. Archetype and Conviction

• Archetype: Margin Inflector.
• Rationale: The setup fits the "Margin Inflector" archetype because the company is demonstrating the ability to expand margins and cash flow (AFFO, EBITDA) through a combination of organic growth (new spectrum, 5G upgrades) and strategic integration (Millicom assets) while managing a known, finite churn event (Sprint/EchoStar/Oi) that is expected to peak in 2026. The "inflection" is the transition from a high-churn environment to a more durable cash flow profile as the churn peaks and new capacity (C-band, FWA) comes online.
• Conviction Stack:
• Thesis Strength: Moderate (Tactical/Setup-led, no external macro thesis).
• Evidence Quality: High. Multiple primary sources (earnings transcripts, SEC filings) from April and May 2026 provide specific, quantified guidance on revenue, churn, and capex.
• Structural Quality: The "Margin Inflector" narrative is supported by the specific data points regarding the peak of churn and the subsequent expected improvement.
• Rerating Potential: Dependent on the successful execution of the "peak churn" narrative and the realization of the increased 2026 guidance.

5. Invalidations, Strengtheners, and Gaps

• Strengtheners: A confirmed breakout above the coil resistance level. Continued evidence of colocation demand exceeding projections in the Millicom assets. Successful closure of the 56 acquired sites by Q3 2026 as expected.
• Gaps in Evidence:
• Valuation Metrics: The provided evidence does not contain current P/E, EV/EBITDA, or AFFO yield multiples as of June 20, 2026. Without these, a precise valuation "fair value" cannot be calculated, only relative to management's growth expectations.

PRIVATE ANALYST CALL

Judgment: Buy Confidence: medium Key evidence: Management increased full-year 2026 outlook for AFFO and EBITDA citing a solid start; U.S. new lease billings up $10M YoY; International churn expected to peak in 2026 with improvement thereafter. Key risks: Churn from Sprint, EchoStar, and Oi exceeds guidance; Millicom integration delays; C-band auction timing shifts. Sizing hint: Position size should reflect the "forming" state of the setup; allocate capital that can be deployed if the breakout fires, but do not over-allocate to a pre-breakout structure. Expected path: Management expects core leasing revenue to increase over 2025 levels in the remainder of 2026; churn is expected to peak and then improve, supporting the margin inflection narrative. Expected horizon: 3 to 6 months (timeframe for the coil to resolve via breakout or invalidation).
