Investment grade telecom bonds are issued by wireless carriers, cable companies, and tower owners rated BBB‑/Baa3 or higher. Subscription revenue is steady, but spectrum purchases and network buildouts keep debt high, so most issuers sit in the BBB category.
For investment grade net lease investors, telecom shows up in two ways: carrier retail stores, many of which are run by authorized dealers rather than the carrier, and cell tower ground leases, where a landowner leases land to a tower company. See the T-Mobile bonds vs. NNN analysis and the investment grade bonds hub.

What Drives Telecom Credit
Spectrum and network spending. Carriers buy spectrum at auction or from other companies and spend heavily on 5G and fiber, usually with borrowed money.
Fiber consolidation. Verizon completed its acquisition of Frontier Communications on January 20, 2026, adding Frontier’s fiber network. Deals like this raise debt in the near term in exchange for long-term growth in fiber customers.
Leverage targets. Agencies watch whether carriers bring debt back toward their stated leverage targets after large purchases; outlooks move with progress on those targets.
Tower economics. Tower companies earn long-term rent from carriers with annual escalators. Their credit depends on carrier spending and on tenant consolidation.
Telecom Issuers That Are Also NNN Tenants
The three national wireless carriers issue bonds and lease retail stores. Many branded stores are operated by authorized dealers, so confirm whether the carrier itself is the tenant. Ratings come from our ratings database and update automatically; n/a means no verified rating is on file. A corporate rating applies to a lease only if the rated entity signs or guarantees it.

Bond Index Yield vs. NNN Cap Rate
The table compares each carrier’s rating-category bond index yield with the median asking cap rate on its active store listings.
| Tenant | S&P / Moody’s | Index yield (category) | Median asking cap rate (listings with a cap rate) | Spread |
|---|---|---|---|---|
| T-Mobile Bonds vs. NNN analysis | BBB+ / n/a | 6.19% (BBB) | 7.25% (9) | +106 bps |

Showing 3 tenants. Index yield is the ICE BofA effective yield index for the tenant’s rating category (US Corporate AAA, AA, A or BBB index; US High Yield BB, single-B or CCC and lower index), using the S&P rating, or the Moody’s equivalent where S&P does not rate, from the Federal Reserve Bank of St. Louis (FRED), as of October 1, 2026. It is an index average, not a quote on the company’s own bonds. Median asking cap rate is the median of asking cap rates (stated, or computed from stated income and price when no rate is stated) on active listings InvestmentGrade.com tracks, listings last observed October 5, 2026; asking cap rates are not closed-sale cap rates. Spread is the median asking cap rate minus the index yield. Ratings are the agency ratings in our ratings database for the entity shown; the rating type (for example issuer, senior unsecured debt, long-term debt or revenue bond ratings) varies by company. The entity that signs or guarantees a given lease can differ, so confirm the lease obligor. Shaded rows are below investment grade. NR means the agency does not rate the entity; n/a means no verified rating is on file.

Telecom Bond Risks
- Leverage after acquisitions. Spectrum and fiber purchases add debt that takes years to pay down.
- Competition. Price competition among carriers and from cable companies pressures margins.
- Tenant consolidation for towers. Carrier mergers can reduce the number of tenants on a tower.
- Dealer-operated stores. A carrier-branded store leased to an authorized dealer carries the dealer’s credit, not the carrier’s.
Frequently Asked Questions
What are investment grade telecom bonds?
Bonds rated BBB‑/Baa3 or higher issued by wireless carriers, cable companies, and tower owners.
How are Verizon, AT&T, and T-Mobile rated?
By S&P, Verizon is rated BBB+, AT&T no verified rating, and T-Mobile BBB+, per our ratings database, which also shows Moody’s ratings and the date each was checked.
Is it better to buy individual telecom bonds or a fund?
It depends on the investor. Individual bonds let you choose issuer and maturity but concentrate risk in a few companies; funds diversify but charge fees and have no maturity date. Relative performance depends on the bonds chosen, timing, costs, and the benchmark.
How do cell tower ground leases fit net lease investing?
A landowner leases a parcel to a tower company, usually for decades with rent escalators. The investor owns land, which is not depreciable, and the lease credit is the tower company’s or its subsidiary’s, so check which entity signed the lease.
