AT&T Inc. 5.350% Global Notes due 2066 (TBB) represent a specific class of AT&T Inc. debt securities that is listed on the New York Stock Exchange under the trading symbol TBB. According to AT&T’s SEC filings, this security is titled AT&T Inc. 5.350% Global Notes due November 1, 2066 and is one of a broad range of AT&T Inc. notes registered and traded alongside the company’s common and preferred equity.

AT&T Inc. is identified in SEC filings as the issuer of TBB and other global notes, with its common shares trading on the New York Stock Exchange under the symbol T. The company’s sector classification for this security on Stock Titan is Telephone Communications (no Radiotelephone). While the detailed business description in the filings provided focuses on financing arrangements and credit facilities, these documents confirm that TBB is part of AT&T’s long-term capital structure.

In the SEC reports, AT&T lists TBB among numerous series of global notes with varying interest rates and maturities, including notes maturing in the 2020s, 2030s, 2040s and 2050s. TBB is specifically identified as one of the longest-dated instruments, with a stated maturity in 2066. This positions TBB as a long-duration note within AT&T’s registered securities.

The filings also show that AT&T actively manages its overall funding and liquidity profile through credit agreements and term loan facilities. For example, AT&T disclosed entry into a Second Amended and Restated Credit Agreement and a Delayed Draw Term Loan Credit Agreement, describing how advances under those facilities may be used for general corporate purposes and how interest is determined with reference to benchmarks such as Term SOFR, EURIBOR and SONIA, plus applicable margins tied to AT&T’s senior unsecured long-term debt ratings. These disclosures provide context for understanding TBB as one component of a broader mix of debt instruments and bank facilities used by AT&T.

AT&T’s SEC filings also describe certain financial covenants associated with its revolving credit facility, including a net debt-to-EBITDA ratio test and a limitation on liens covenant. While these covenants are tied to the credit agreement rather than to TBB specifically, they illustrate the framework within which AT&T manages leverage and obligations across its capital structure, including its global notes.

TBB is listed in SEC reports alongside AT&T’s common stock, preferred stock depositary shares and multiple series of global notes. This confirms that TBB is an exchange-listed security registered under Section 12(b) of the Securities Exchange Act of 1934. The filings also show that AT&T periodically issues additional notes and may remove certain note series from listing via Form 25 filings when they are being removed from a particular exchange. These Form 25 filings reference other series of global notes, demonstrating that AT&T adjusts its listed debt profile over time.

Security and issuer context

In the SEC filings, AT&T lists TBB together with its common shares, preferred stock depositary shares and many other note series, all registered under Section 12(b).

The filings also show that AT&T uses registration statements and prospectus supplements to issue new notes, and that it may file Form 8-K reports to document material financing transactions and note offerings.

For users evaluating TBB, these disclosures underscore that the note is part of a structured program of global note issuance by AT&T, rather than a standalone financing. The maturity date and coupon rate (5.350%) are embedded in the security’s title as presented in the SEC documents.
