SBA Communications (SBAC) Q2 2026 earnings review

International Boom Masks Domestic Churn and AFFO Decline

SBA Communications delivered a mixed quarter characterized by a stark divergence between its domestic and international businesses. Total revenue grew a modest 2.3% YoY to $715.3M, driven entirely by a 30.5% surge in international site leasing following the Millicom integration and new builds in Central America. However, the core U.S. market is reversing, with domestic site leasing shrinking 3.7% YoY due to ongoing Sprint and EchoStar churn. More concerning for investors, higher interest rates and churn pushed Net Income down 12.9% YoY and AFFO per share down 3.8% YoY. Management's successful issuance of $3.5B in investment-grade notes fortifies the balance sheet, but profitability metrics are firmly decelerating.

🐂 Bull Case

International Growth Engine Firing

International site leasing revenue accelerated massively, up 30.5% YoY to $211.4M. The newly integrated Millicom assets and active build-to-suit programs in Central America are significantly outperforming legacy domestic growth.

Investment-Grade Transformation Complete

SBAC successfully issued $3.5B in unsecured notes and replaced its secured revolver with a new $2.5B unsecured facility. Earning an S&P BBB rating secures a lower long-term cost of capital.

🐻 Bear Case

Domestic Leasing is Shrinking

U.S. site leasing revenue is reversing, falling 3.7% YoY. Customer consolidation (Sprint) and litigation/non-payment (EchoStar) are eroding the highest-margin segment of the business.

Interest Rates Crushing the Bottom Line

Net cash interest expense rose 9.5% YoY to $122.1M. This macro headwind is the primary culprit behind the 5.2% drop in AFFO and 12.9% decline in Net Income.

⚖️ Verdict: ⚪

Neutral. The company is making all the right strategic moves with its balance sheet and international portfolio, but it is impossible to ignore that its primary cash cow (U.S. leasing) and its primary valuation metric (AFFO) are both moving in the wrong direction.

Key Themes

DRIVER 🟢🟢

International Site Leasing Acceleration

International leasing is accelerating dramatically, posting $211.4M in revenue (+30.5% YoY) and generating $148.8M in segment operating profit (+31.9% YoY). The successful integration of the Millicom portfolio, coupled with an aggressive build-to-suit campaign in Central America (building 109 towers in Q2 alone), has transformed international operations into SBAC's sole organic growth engine.

DRIVER NEW 🟢

Investment-Grade Capital Structure Achieved

Management delivered on its multi-year promise to achieve an investment-grade rating (S&P upgraded to BBB). The company subsequently executed a massive $3.5B unsecured senior notes offering (blended rate 5.113%). The proceeds retired the secured Revolving Credit Facility and the 2024 Term Loan, shifting the capital structure away from secured debt and providing significant long-term flexibility.

DRIVER

5G Densification and Emerging 6G Architecture

Despite current churn headwinds, underlying demand remains stable due to carrier network modernization. Customers are actively deploying upper C-band spectrum, massive MIMO antennas, and preparing for future 6G architectures. These technological requirements ensure a durable floor for future colocation demand on existing macro sites.

CONCERN 🔴🔴

Domestic Site Leasing Reversing

The domestic leasing segment—historically the crown jewel—is reversing. Q2 revenue fell 3.7% YoY to $452.5M, and operating profit dropped 4.8% YoY to $381.0M. The ongoing Sprint consolidation and the removal of EchoStar revenue due to litigation have severely handicapped U.S. growth, contradicting the narrative of an insatiable U.S. data demand boom.

CONCERN 🔴

Macro Headwind: Interest Rates Compressing AFFO

Elevated interest rates are actively suppressing shareholder returns. Net cash interest expense increased 9.5% YoY to $122.1M. This macro reality is directly responsible for AFFO declining 5.2% to $324.4M. Until the debt refinancing cycle normalizes at lower rates, bottom-line growth will remain stunted.

CONCERN NEW 🔴

Site Development Collapse

Site development revenue is heavily decelerating, down 23.5% YoY to $51.4M. Operating profit for the segment fell from $13.7M to $9.5M, and margins compressed from 20.3% to 18.4%. This sharp pullback in services work reflects tighter carrier capital expenditure environments in the U.S.

Other KPIs

Tower Cash Flow Margin 79.5%

Decelerating from 81.0% in Q2 2025. The margin compression is driven by a mix shift toward the lower-margin international segment (70.4% margin) and away from the high-margin domestic segment (84.2% margin).

Net Debt to Annualized Adjusted EBITDA 6.4x

Stable. The leverage ratio remains comfortably in the middle of management's target range of 6.0x to 7.0x. Total debt stands at $12.8B, but the recent $3.5B debt restructuring drastically improves the quality and maturity profile of these liabilities.

Guidance

FY26 Total Revenues $2,841M - $2,886M

Stable. The midpoint of $2,863.5M represents a slight $2.0M increase from prior guidance, primarily reflecting small international FX and operational tweaks. Implies a relatively flat trajectory compared to FY25 ($2,818M derived).

FY26 AFFO per Share $11.95 - $12.40

Stable. The midpoint of $12.175 was raised by $0.02 from prior outlook. However, this still represents a YoY deceleration compared to FY25 ($12.87 estimated midpoint), primarily due to the heavier interest burden and domestic churn.

FY26 Adjusted EBITDA $1,920M - $1,940M

Decelerating slightly against prior expectations. Management actually lowered the midpoint of this guide by $1.0M from the April outlook, reflecting minor cost pressures despite the slight revenue raise.

Key Questions

Path to Domestic Growth

With domestic site leasing down 3.7% YoY, at what exact quarter do you model the Sprint and EchoStar churn fully washing out to allow U.S. revenues to inflect positively again?

Site Development Visibility

Site development revenue collapsed over 23% this quarter. Is this a temporary lull in carrier CapEx timing, or a structural downward reset in services demand for the rest of 2026?

M&A vs Buybacks under IG

Now that you have achieved investment-grade status and restructured $3.5B in debt, how does this alter the threshold for aggressive share repurchases versus acquiring more international assets?
