AD vs CCI: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of November 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: CCI is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. AD and CCI share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined AD and CCI exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Array Digital Infrastructure owns and leases about 4,400 cell towers across the United States. It used to be United States Cellular Corporation, a regional wireless carrier, until it sold its retail wireless operations to T-Mobile for roughly $4.3 billion (closed August 2025) and renamed itself Array that same month. What survived the sale is the real estate: the towers, the ground leases, and the residual spectrum. The company then sold 3.45 GHz and 700 MHz licenses to AT&T for ~$1.018 billion (closed January 2026, producing a ~$156.6 million book gain), and further licenses to Verizon for ~$1.0 billion and T-Mobile for ~$168 million (closed June 2026), while retaining its C-band holdings. Headcount is about 60 people. Telephone and Data Systems, the Carlson-family-controlled parent, holds roughly 81.9% of the economics and about 95.9% of the voting power.

Crown Castle owns, operates, and leases shared communications infrastructure geographically dispersed across every major U.S. market, comprising approximately 40,000 cell towers and, until May 2026, roughly 90,000 route miles of fiber supporting small cells and fiber solutions. The company's revenue model is essentially that of a landlord: wireless carriers including Verizon, AT&T, and T-Mobile sign long-term leases to place their antennas and equipment on Crown Castle's structures, generating predictable, escalating site rental revenues. Because each tower can host multiple tenants simultaneously with minimal incremental cost, the model carries high operating leverage, and the tower segment has historically operated with very high margins on incremental revenue. Crown Castle converted to a Real Estate Investment Trust (REIT) structure in 2014, which requires it to distribute most of its taxable income as dividends. The company traces its roots to Castle Tower, founded in Houston in 1994 with 133 towers, which later merged with Crown Communications to form Crown Castle; it went public in 1998. Over the following decade it spent heavily on acquisitions, including fiber assets, accumulating a debt load of roughly $24 billion. Persistent activist pressure from Elliott Investment Management ultimately drove a strategic reversal: the company divested its fiber and small cell businesses in May 2026 for approximately $8.5 billion in total, deploying proceeds primarily toward debt reduction and share repurchases. Christian Hillabrant, who previously served as CEO of Vantage Towers AG and COO of Tillman Infrastructure, was appointed President and CEO effective September 15, 2025, and brings over three decades of digital infrastructure experience.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• AD drivers: The T-Mobile master license agreement converts internal towers into rent; Remaining spectrum is an unmonetized asset sitting inside the enterprise value.
• CCI drivers: Pure-Play Tower Focus Unlocks Operational Simplicity; 5G Densification Keeps Tower Demand Structural.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The single largest risk is tenant concentration in the other direction: the T-Mobile MLA provides interim licenses of up to 30 months on the remaining ~1,800 towers not covered by the long-term commitment, so a large block of sites faces a potential decommissioning cliff once T-Mobile finishes its network integration. For CCI, crown Castle's most acute risk is customer concentration: approximately 75% of revenue comes from just three carriers, and the DISH Wireless default vividly illustrates what happens when even a smaller tenant stops paying, resulting in contract termination and over $3.5 billion in disputed payments now in litigation.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick AD if you believe its drivers more; CCI if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the AD and CCI guides.

AD. Standard multiples still do not describe this security well. The trailing P/E of ~4.4 measures one-time spectrum gains, while the forward P/E of ~35 on 2027 consensus EPS of ~$0.97 and EV/EBITDA near 69 reflect how little operating profit the towers produce yet, far richer than American Tower, Crown Castle or SBA Communications. Unmonetized spectrum and cash sit inside the enterprise value while contributing no operating income. Since the TDS proposal was withdrawn on September 1, 2026, the stock has drifted to ~$33.75, near its 52-week low of ~$32.68, against a thin three-analyst consensus target of ~$43.33; the next report is expected around November 9.

CCI. At $82.58 on October 16, 2026, Crown Castle trades at about 34 times trailing and 28 times forward earnings and about 21 times EBITDA, multiples that look high on GAAP numbers because depreciation on long-lived towers depresses net income; AFFO remains the more relevant cash measure for a tower REIT. The 5.3% yield on the $4.25 dividend sits near the top of the tower peer group after the stock's 2026 decline. Q3 results on October 21 (consensus EPS about $0.68 on $1.01 billion of revenue) are the next test of the post-sale earnings base.

Headline figures (approximate, October 2026): AD shows revenue (ttm) ~$214 million (Q2 2026 up ~89.5% yoy), q2 2026 revenue / net income ~$54 million / ~$359 million (spectrum gains), net income (ttm) ~$664 million, mostly one-time spectrum gains, p/e (trailing / forward) ~4.4x / ~35x; CCI shows revenue (ttm) ~$4.16 billion, revenue growth (q2 2026, yoy) ~-4.9% (post-divestiture), operating margin (ttm) ~47%, net income (ttm) ~$1.07 billion.

AD and CCI are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined AD and CCI exposure against your real portfolio. It is not an investment adviser.
