SBAC · Q2 2025 Earnings
BullishSBA Communications
Reported August 4, 2025
30-second summary
Six straight quarters of bookings growth, a ~20% services revenue guide raise, and an early partial close on the Millicom acquisition (~4,300 sites added) drove management to lift every key full-year metric. Offsetting risks are real but contained: $50M of Sprint churn lands in 2026, OI churn in Brazil pushed the international churn assumption up $5M, and a $12.5B debt stack at 3.7% will refinance into a meaningfully higher rate environment over several years. The Canada sale at ~30x AFFO pre-tax validates the private/public valuation gap management has been pointing to.

Management tone
Management's posture this quarter is meaningfully more constructive than the typical tower-REIT defensive stance. Five distinct shifts stand out, each grounded in a specific disclosure.
Bookings momentum reframed from "below peak" to "sustained and building." Management framed Q2 as the "sixth sequential quarter where bookings increased… positive momentum continues to build, and we are encouraged by the sustained levels of activity." Critically, they paired the optimism with a reality check — "while not at the peak levels enjoyed back in '21 and '22" — which lends the bullishness credibility. The signal is a multi-quarter durable cycle, not a one-quarter pop.
Services revenue went from quietly tracking to the most aggressive guide raise on the print. "We are increasing our full year services revenue guidance by almost 20%." This is the single largest forward-looking change in the release and ties directly to construction velocity — meaning carriers are not just signing leases but funding the buildouts behind them.
International churn was acknowledged, quantified, and customer-named. Management stated, "we believe this to be temporary," but the $5M increase to international churn explicitly tied to OI in Brazil represents a sharper disclosure than the typical "elevated churn" boilerplate. Naming the customer signals confidence the situation is contained rather than spreading.
Portfolio rationalization moved from incremental opportunity to active reshaping. With ~4,300 sites added via the Millicom partial close and the entire Canadian tower portfolio sold at ~30x AFFO pre-tax (mid-to-upper 20s post-tax), management has shifted from passive holder to active capital recycler. The framing — "immediately accretive to AFFO per share upon closing" for Millicom; disciplined exit pricing for Canada — positions both moves as offense.
Spectrum moved from future possibility to scheduled catalyst. The reinstated FCC Spectrum Auction Authority plus 800 MHz of identified new spectrum is now framed as near-term, with management noting new spectrum "will require new equipment at our cell towers, particularly at the higher bands." This is the first time spectrum is positioned as a concrete forward driver rather than optionality.
Recurring themes management leaned on this quarter:

Q&A highlights
John Atkin · RBC
How durable are the demand drivers (FWA intensification, coverage) through end of 2025 and 2026, and what are the drivers of churn and rent reduction initiatives?
Management expressed confidence in durability of FWA and other demand drivers extending multiple years based on subscriber growth expectations and network capacity needs. Stated there are no material rent reduction initiatives underway, emphasizing balanced pricing that's fair to both customers and the company.
Richard Cho · JP Morgan
Significant collocation activity signed but revenue hasn't fully materialized yet. What is the timing of revenue recognition?
Management explained the shift towards more new collocations versus amendments delays revenue recognition timing, as new leases take longer to install and commence revenue than amendments. Full year outlook for new leases and amendments unchanged; second half must deliver more contribution to meet targets.
Jim Schneider · Goldman Sachs
Has FWA densification activity broadened beyond single lead customer? What is the exposure and churn risk from U.S. Cellular and DISH transactions?
FWA activity has broadened among all major customers with the gap between the leading carrier and others closing. U.S. Cellular represents $20M annual revenue with no immediate churn plan; even if all lost would be small impact over multiple years. DISH represents $55M annual revenue; company continues to serve them with ongoing lease signings and amendments.
Rick Prentice · Raymond James
Clarification on Sprint churn timing and Canadian asset sale valuation metrics (AFFO multiple, cash flow definition).
Sprint churn of $50M in 2026 followed by remaining $20M total (not annual) expected mostly in 2027. Canadian sale valued at 30x AFFO pre-tax, mid to upper 20s post capital gains tax. $27M Canadian lease revenue and $15M Canadian after-tax cash flow basis for calculation.
Michael Rollins · Citi
What is the right/fair level of annual AFFO per share growth and what inning are we in regarding normalization of costs and challenges?
Management indicated mid to high single-digit AFFO per share growth is sustainable after normalizing for refinancing headwind of $12.5B debt portfolio at 3.7% average rate being refinanced at higher rates. Significant headwind expected for several years until low-cost debt matures and is refinanced. Three upcoming maturities have one-handle coupons, creating significant interest rate spreads.
What to watch into next quarter
Whether the seventh sequential quarter of bookings growth materializes, and whether new-collocation revenue begins flowing through to reported domestic site leasing growth (currently +1.4% YoY despite booking strength).
The Millicom full close (expected by September 1) and Canada sale close timing — both are excluded from current guidance, so any 2026 walk will depend on disclosure of accretion math at close.
OI Brazil situation: whether the $5M international churn increase fully captures the risk or whether additional churn flows through, and whether the "temporary" framing holds.
Updated quantification of the 2026 Sprint churn step-down ($50M) against offsetting growth — this is the most identifiable forward headwind and management's framing of how leasing momentum offsets it will shape 2026 modeling.
Any commentary on refinancing pacing for the three near-term maturities with one-handle coupons — the spread to current rates is the single largest determinant of normalized AFFO/share growth.
Spectrum auction timing for the 800 MHz tranche and any early commentary from carriers on equipment deployment plans tied to it.
