SBA Communications leverages a strong international presence and superior net margins to drive growth.
Crown Castle maintains a dominant U.S. focus with significant investments in fiber and small cell technology.
Which tower infrastructure giant is the better fit for your portfolio in 2026?
The build-out of 5G networks remains a massive multiyear tailwind for the real estate sector. Choosing between SBA Communications (NASDAQ:SBAC) and Crown Castle (NYSE:CCI) requires weighing international growth against domestic fiber strength.
Both companies operate as real estate investment trusts (REITs), owning the essential infrastructure that allows your smartphone to function. While they share similar business models, their geographic focuses and asset mixes differ significantly. One prioritizes global expansion while the other bets heavily on U.S. small cells and fiber to complement its traditional tower portfolio.
SBA Communications provides essential infrastructure by leasing tower space to wireless providers. Its primary customers include T-Mobile, AT&T, and Verizon. T-Mobile alone accounted for more than 31% of total revenue in 2024, and customer concentration like this adds a layer of risk to the business.
In FY 2025, revenue reached nearly $2.8 billion, which was a growth rate of approximately 5.1% from the previous year. The company reported net income of roughly $1.1 billion during this period. This led to a net margin of approximately 37.4%, which measures how much of each dollar earned becomes profit.
As of its December 2025 balance sheet, the debt-to-equity ratio was -3.2x, indicating that total liabilities exceed shareholder equity. The current ratio, which compares short-term assets to short-term liabilities, was roughly 0.5x. For the year, the company generated free cash flow of close to $1.1 billion.
Crown Castle focuses its operations on U.S. infrastructure, managing more than 40,000 towers and 90,000 miles of fiber. The big three carriers accounted for roughly 90% of site rental revenue in FY 2025, representing significant customer concentration risk. The company also builds small cell nodes to support high-density wireless demand in urban areas.
For FY 2025, revenue was nearly $4.3 billion, representing a decrease of about 35.1% over the prior year. Net income for the fiscal year was approximately $444.0 million. This resulted in a net margin of roughly 10.4%, showing how much revenue remains after all costs are paid.
According to its December 2025 balance sheet, the debt-to-equity ratio was -18.1x, which means total liabilities exceed shareholder equity. The current ratio was approximately 0.3x. Free cash flow for the year was roughly $2.9 billion, providing significant capital for reinvestment.
SBA Communications faces risks from a small customer base, particularly with the recent default of EchoStar. This default is expected to lead to a revenue loss of about $56.0 million in 2026. The company also deals with competition from other infrastructure providers like American Tower and must manage currency swings in international markets.
Crown Castle carries a substantial debt load of approximately $24.2 billion, which limits its flexibility to pursue new projects. The company is currently involved in a dispute with EchoStar, asserting that the carrier owes more than $3.5 billion under existing agreements. Competition in the U.S. market from firms like Equinix or carrier self-performance can also pressure lease rates.
SBA Communications currently trades at a lower forward P/E and P/S ratio than its peer based on future earnings estimates.
| Metric | SBA Communications | Crown Castle | Sector Benchmark | |---|---|---|---| | Forward P/E | 26.9x | 42.9x | 32.2x | | P/S ratio | 7.5x | 9.2x | n/a |
SBA, Crown Castle, and American Tower are the three big publicly traded tower companies. They’re REITs, which means they operate like landlords, renting the infrastructure and physical space to providers of cell connectivity. It’s an intriguing idea for an investment, as these companies receive predictable recurring income from major telecoms and operate in an industry that is viewed as a utility.
But there are risks across the board, and the fallout from the EchoStar default and subsequent legal battle is one example. Both SBA and Crown Castle have relatively small customer bases, and if one tenant struggles financially, it can send shockwaves through the balance sheet. SBA is the smallest of the three, both in terms of market cap and in total number of towers. In April, tower stocks responded favorably to rumors that SBA Communications may be the target of an acquisition by infrastructure management companies KKR and Brookfield.
Tower stocks have been losing investments over the past five years, with SBA stock down more than 36% and Crown Castle losing about 55% in that time frame. A major acquisition in the industry could reinvigorate the investment narrative, as could interest from adjacent industries like data centers or satellite internet.
Choosing between SBA and Crown Castle may come down to your geographic preferences. SBA operates in North America, South America, Central America, and Africa, while Crown Castle is more concentrated in the United States. I think SBA’s valuation, superior financials, and potential for an acquisition make it the more interesting choice here, but prospective long-term investors should consider what they believe the industry will look like over the next five to 10 years before making a decision.

Four leading AI models discuss this article
"SBAC offers the best odds of a valuation re-rating driven by margin superiority and international growth optionality, provided currency and tenant concentration risks stay manageable."
Interesting matchup: the article leans SBA on margins and international reach while casting Crown Castle as a US-focused fiber and small-cell engine. However, two gaps matter. First, several balance-sheet figures look inconsistent (debt-to-equity appears negative), undermining confidence in the stated leverage and risk posture. Second, it glosses critical risks: EchoStar’s dispute, currency and political risk in non-US markets, and Crown’s potential to monetize fiber and edge initiatives in a rising-rate backdrop. My take: SBA looks best on margin superiority and optionality around a potential megadeal that could re-rate the stock, but Crown Castle could still outperform if US fiber/small cells accelerate faster than feared and currency headwinds stay contained.
Crown Castle’s US-centric model could yield steadier cash flow and lower geopolitical risk, potentially outperforming SBAC if currency swings derail international expansion or if the US 5G capex cycle accelerates faster than SBAC's growth curve.
"The tower REIT business model is facing a secular decline as carrier consolidation and technological shifts diminish the pricing power of passive infrastructure owners."
The article frames this as a choice between geographic exposure and fiber, but it misses the structural shift in tower economics. SBA’s 37.4% net margin is impressive, but it masks the reality that the 'tower REIT' model is facing terminal headwinds: carrier consolidation and the transition to Open RAN, which may reduce the need for physical tower density. Crown Castle’s 35% revenue drop highlights the brutal reality of the 'small cell' pivot—it is capital-intensive and yielding poor returns on invested capital. With both companies carrying negative book equity (due to aggressive depreciation and debt), valuation metrics like P/E are misleading. I am bearish on the sector until they prove they can grow AFFO (Adjusted Funds From Operations) without massive debt-fueled capex.
If interest rates decline significantly in 2026, the high dividend yields of these REITs could trigger a massive rotation back into the sector, regardless of their underlying operational stagnation.
"Both tower REITs face structural headwinds (5G cycle maturity, customer concentration, leverage), and SBAC's valuation discount reflects hidden margin compression from EchoStar's default, not genuine alpha."
The article's valuation argument for SBAC (26.9x forward P/E vs. CCI's 42.9x) collapses under scrutiny. SBAC's 37.4% net margin is inflated by a $56M EchoStar revenue cliff in 2026—strip that out and margins compress materially. More critically: both companies have negative debt-to-equity ratios (SBAC -3.2x, CCI -18.1x), meaning liabilities dwarf equity. This isn't a capital structure quirk; it's leverage masking deteriorating fundamentals. CCI's 35% revenue decline year-over-year is buried in a single sentence. The article frames 5G as a tailwind, but that cycle peaked in 2022-2023. Current growth is sub-3% industry-wide. The acquisition rumor about KKR/Brookfield is speculative noise.
If 5G densification accelerates into 2027-2028 and fiber monetization accelerates faster than consensus expects, SBAC's international optionality and lower leverage multiples could re-rate sharply—especially if a strategic buyer emerges.
"EchoStar defaults and negative equity leave SBAC's margin advantage vulnerable to 2026 shocks the article understates."
The article positions SBAC as preferable due to 37.4% net margins, 5.1% revenue growth to $2.8B, and 26.9x forward P/E versus CCI's 10.4% margins and 42.9x multiple, plus acquisition rumors. Yet both show negative equity on their balance sheets, extreme customer concentration (T-Mobile >31% for SBAC; big three ~90% for CCI), and shared EchoStar default exposure that will cut 2026 revenue by at least $56M at SBAC alone. International currency swings and CCI's $24.2B debt plus $3.5B legal claim add unpriced downside. Five-year total returns already reflect structural headwinds in tower leasing.
SBAC's lower multiple and rumored KKR/Brookfield interest already embed these concentration and leverage risks, so any resolution of the EchoStar dispute could trigger rapid re-rating beyond what domestic-focused CCI offers.
"Data-quality concerns about negative D/E figures could reverse leverage risk and valuation if misreported; verify balance sheets before betting on margins."
Claude’s emphasis on negative debt-to-equity figures and the EchoStar-induced margin distortion risks a data-quality issue more than a structural truth. If SBAC and CCI truly carry negative D/E, that would imply extreme leverage masking and could justify a re-rating threshold far from current reader takeaway. Before trading theses on margins, confirm financials; a misreported or misinterpreted balance sheet could invert the risk/reward of both names.
"Negative book equity is an artifact of REIT accounting for depreciation, not a proxy for imminent insolvency or deteriorating fundamentals."
Claude and Grok are conflating negative book equity with insolvency. These are REITs; they carry massive depreciation on long-lived assets, which artificially depresses book value while cash flows remain highly stable. Focusing on D/E ratios here is a category error. The real risk isn't the balance sheet—it's the terminal value of the towers. If Open RAN reduces carrier demand for macro sites, these companies become glorified landlords of depreciating metal, regardless of their leverage.
"Negative book equity + extreme customer concentration = leverage masking, not accounting artifact—the cash flow stability Gemini invokes depends entirely on carrier capex discipline."
Gemini's REIT depreciation defense is textbook correct—but it dodges Claude's real point: negative book equity combined with 90%+ customer concentration means these aren't stable landlords, they're highly leveraged bets on three carriers' capex cycles. Open RAN risk is real, but the immediate risk is carrier consolidation or a single major customer renegotiating rates downward. Depreciation accounting doesn't protect cash flow if demand contracts.
"Litigation exposure on negative equity creates an unpriced CCI-specific tail risk beyond shared sector headwinds."
Gemini rightly flags REIT depreciation as non-threatening to cash flows, but this ignores how negative equity leaves zero buffer against the $3.5B legal claim on CCI. An adverse ruling would likely trigger asset sales or added leverage precisely when Open RAN and carrier consolidation already threaten tower demand. SBAC faces parallel EchoStar exposure without that litigation overhang, creating divergent downside paths the margin debate misses.
The panel consensus is bearish on both SBA Communications (SBAC) and Crown Castle (CCI) due to significant risks outweighing potential benefits. Key concerns include negative equity, customer concentration, EchoStar's dispute, and structural headwinds from Open RAN and carrier consolidation.
