CCI — Q3 2026 Financial Report Analysis

Overview

Crown Castle's third quarter of 2026, its first full quarter as a towers-only company, showed the same split as the second: the towers took in less rent, but cash earnings per share rose. Site rental revenue fell 4.5% to $966 million, almost entirely because DISH stopped paying. AFFO per share rose 11% to $1.24, because the fiber and small-cell sale in May let the company pay down debt and buy back shares, which cut interest costs and the share count. Total GAAP net income fell 12% to $283 million, but only because Q3 2025 still included $46 million of profit from the fiber business that has since been sold; profit from the towers alone rose 2%. Management raised its full-year AFFO guidance by $5 million, to a $1,980 million midpoint, but said leasing from new tenants will land at the bottom of its forecast range.

All operating figures below are for continuing operations (towers) unless stated. The fiber and small-cells business, sold on May 1, 2026, is reported as "discontinued operations" through April 30, 2026, so the Q3 2025 comparison column contains its results only in the total net income line.

What AFFO is, and why it leads for a tower REIT

A REIT (real estate investment trust) must pay out most of its taxable income as dividends, and in return pays almost no corporate income tax ($5 million this quarter). What matters to its shareholders is the recurring cash available to pay those dividends. AFFO (adjusted funds from operations) is the industry's measure of that: it starts from net income, adds back depreciation (large and non-cash for a company that owns 40,000 physical towers: $180 million this quarter), removes accounting smoothing of rent and one-off gains or losses, and subtracts the small amount of capital spending needed to keep the towers in service ($8 million this quarter). AFFO is a company-defined, unaudited measure; the figures here come from Crown Castle's Q3 2026 earnings release (8-K Exhibit 99.1, filed October 21, 2026). The full 10-Q has not been filed yet, so some detail (DISH litigation, debt notes) is not yet available for this quarter.

Key metrics (Q3 2026, three months ended September 30)

*Non-GAAP measures from the company's Q3 2026 earnings release. Operating margin is operating income as a share of net revenues: the share of revenue left after running the business, before interest and tax. Adjusted EBITDA is earnings before interest, tax, depreciation and amortization, also excluding stock-based pay and one-off charges.

Year to date (nine months ended September 30): net revenues of $3,013M (-5.6% from $3,193M); site rental revenues of $2,894M (-4.5% from $3,031M); income from continuing operations of $803M (-2.8% from $826M); total net income of $528M versus $150M, because the 2025 period carried a $1,313M loss on the fiber sale against $625M this year; AFFO of $1,465M (+3.6% from $1,414M), or $3.39 per share versus $3.24.

Site rental revenue: what grew and what DISH took away

Crown Castle breaks the $46 million revenue decline into parts (release, "Components of Changes in Site Rental Revenues"):

Three points stand out:

• The core business is growing, but more slowly. Organic growth of $35 million is 3.8% of last year's billings when DISH is left out of the base, down from 4.2% in Q2 and 4.1% a year ago. The slowdown is in new leasing: $16 million versus $20 million. Escalators, which are fixed by contract, did their job (+$25 million).
• DISH accounts for more than the whole decline. Crown Castle stopped recognizing DISH revenue from January 1, 2026, after terminating its leases for non-payment. That cost $61 million in the quarter, against $35 million of organic growth.
• Sprint is nearly finished. T-Mobile's removal of duplicate Sprint equipment cost $5 million, against $51 million a year ago. That headwind is fading.

Services revenue (site preparation and installation work for carriers, not long-term rent) fell to $29 million from $60 million, and its gross profit fell to $16 million from $30 million. Lower carrier activity also shows up in the leasing slowdown above. Management said the full-year core leasing figure will land "towards the bottom end" of its $60–70 million range.

Lower costs, lower interest, fewer shares

• Overhead fell. Selling, general and administrative expense dropped 15% to $82 million, as the headcount-reduction plan announced in February takes effect ($6 million of restructuring charges this quarter, $20 million year to date). Site operating costs were flat at $248 million.
• Interest fell sharply. Interest expense dropped to $177 million from $247 million (-28%), because the sale proceeds repaid about $7 billion of debt in Q2 and July. Interest income fell back to $3 million from $18 million in Q2: the sale cash that earned interest in Q2 has now been spent.
• Fewer shares. The $1.0 billion buyback finished in Q2 left 426 million diluted shares, down from 437 million a year ago. No shares were repurchased in Q3 (treasury stock is unchanged at 11 million shares, $1.0 billion).

The AFFO bridge in the release makes the source of growth plain: AFFO rose $40 million while Adjusted EBITDA fell $45 million. The difference is almost entirely the $70 million drop in interest expense.

A customer deal and more land purchases

The CFO said that in the quarter Crown Castle "acquired an outstanding residual economic interest on a subset of our tower sites and extended the term of a significant customer on those sites." The release does not name the customer or the price. Two lines are consistent with it: the cash-flow statement shows $157 million of "acquisition of intangible assets" year to date (none in 2025), and other intangible assets on the balance sheet rose to $184 million from $27 million at year-end. The guidance raise ties back to it: longer contract terms add $20 million to straight-lined revenue in the 2026 outlook (an accounting effect, not extra cash billed).

Crown Castle is also buying the land under its towers to stop paying ground rent: purchases of land interests were $40 million in Q3, up from $16 million a year ago, and the main reason total capital spending rose 57% to $66 million. About 57% of its towers still sit on leased ground. The full-year discretionary capex guide rose by $40 million, to $190–290 million, for more of these buyouts.

Debt and balance sheet

• Total debt (face value) is about $17.9 billion and net debt is $17.6 billion, or 6.5x last-quarter annualized Adjusted EBITDA, up from 6.3x in Q2. Leverage ticked up because Adjusted EBITDA fell while spending on land and the customer deal came on top of a dividend that uses most of AFFO.
• The $1.0 billion of 1.050% notes due July 2026 were repaid. The company now has $450 million drawn on its revolving credit line and $100 million of commercial paper (short-term corporate IOUs), so 97% of debt is fixed-rate, down from 100% in Q2. Weighted-average maturity is about 7 years.
• $2.24 billion is due within 12 months, including $718 million of 2.900% notes and $500 million of 4.000% notes in March 2027 and $979 million of 3.650% notes in September 2027. Covenant net leverage is 6.4x against a 7.0x limit, with $4.0 billion undrawn on the revolver.

What the headline numbers hide

• The net income decline is a comparison effect, not a weaker quarter. Q3 2025 included $46 million of income from the fiber business (its $277 million operating profit less a $231 million loss on disposal). Continuing income rose 2.2% to $283 million. No further disposal loss was booked in Q3; the year-to-date loss stays at $625 million.
• GAAP vs AFFO gap. AFFO ($530 million) exceeded net income ($283 million) by $247 million. The main add-backs are real-estate depreciation ($157 million), non-real-estate depreciation ($23 million, up from $4 million; the release does not explain the jump), straight-line revenue ($25 million), straight-line expense ($13 million), stock-based pay ($18 million) and restructuring ($6 million), less $8 million of maintenance capex. Stock-based pay is a real cost to shareholders that AFFO leaves out.
• AFFO growth came from financing, not operations. Adjusted EBITDA fell 6.3%. Almost all of the 10.7% rise in AFFO per share came from lower interest and a 2.5% lower share count. That boost is a one-time step from the sale, and it will drop out of year-over-year comparisons after Q2 2027.
• Cash conversion is fine. Year-to-date operating cash flow from continuing operations was about $1,145 million (total $1,253 million less $108 million from discontinued operations), compared with $803 million of continuing net income. The excess is mostly depreciation.
• Guidance: raised, but quality is mixed. The $25 million Adjusted EBITDA raise is made of $20 million straight-lined revenue (non-cash) and $5 million lower costs. Only the $5 million cost saving reaches AFFO. Core leasing was steered to the bottom of its range.

Did last time's read hold up?

Our Q2 report listed four things to watch. (1) Organic growth near 4%: it slipped to 3.8% ex-DISH from 4.2%, and leasing guidance moved to the low end. (2) DISH recovery: the release gives no update and the outlook assumes nothing from DISH; the supplement still counts about $3.5 billion of DISH receivables within contracted revenue. (3) The $124 million fiber price adjustment: no further loss on disposal was booked in Q3, and the release says nothing more. (4) March 2027 maturities: both notes are still outstanding, and the July maturity was partly funded with floating-rate revolver and commercial paper borrowing. We also estimated the guide implied about $520 million of AFFO per quarter in H2. Q3 came in at $530 million, and the new guide implies about $515 million for Q4.

Takeaway: Crown Castle's per-share cash earnings are rising only because the fiber sale cut its interest bill and share count. The towers themselves are earning less: Adjusted EBITDA fell 6% and new-tenant leasing slowed to $16 million from $20 million. Once the financing benefit drops out of comparisons in mid-2027, AFFO growth will depend on organic rent growth that is now running below 4% and drifting lower.

Outlook

Management's full-year 2026 outlook (October 21, 2026, midpoints):

Organic growth excluding DISH and Sprint is still guided at about $135 million for the year (3.6% with DISH removed from the prior-year base). Interest expense guidance is unchanged at $787–832 million.

Our read: The guide implies Q4 AFFO of about $515 million ($1.21 per share), slightly below Q3, so Q3 looks like the high point of 2026. For 2027, the easy gains from lower interest are over, and the company is borrowing again (revolver, commercial paper) with $2.2 billion of maturities ahead that carry 2.9%–4.0% coupons and would likely be refinanced at higher rates. The dividend now uses about 86% of AFFO, which leaves little room for buybacks without more debt. The items worth watching next quarter are whether core leasing recovers from $16 million a quarter, how the March 2027 notes are refinanced, and whether the 10-Q gives any number for a DISH recovery from its bankruptcy or the FCC-mandated trust. Any DISH recovery would be upside the guide doesn't include.
