AT&T Inc. significantly expanded its debt offerings in early to mid-2026, issuing multiple tranches of bonds across different currencies. On April 27, 2026, the company issued international bonds in U.S. dollars totaling $4.75 billion, with maturities in 2036 ($1.75 billion), 2056 ($2 billion), and 2066 ($1 billion). These issues reflect a strategic move to raise substantial capital, leveraging favorable market conditions. The issuance details indicate a focus on long-term funding with maturities extending several decades into the future.

Prior to the U.S. dollar offerings, on March 7, 2026, AT&T also issued bonds denominated in Canadian dollars. These included two tranches: CAD $1.25 billion maturing in 2036 and CAD $1 billion maturing in 2056. These Canadian dollar bonds further diversified AT&T's funding sources and demonstrated their presence in the international debt markets beyond the euro and U.S. dollar. The euro equivalent of these bond sales was a significant amount, with one offering of 1.75 billion euros and another specific bond, "AT&T Inc, 3.55% 15sep2037, GBP (XS1778829504)", having an equivalent in U.S. dollars of $1,342,500,000, and a volume in circulation of 1,000,000,000 GBP.

These bond issuances by AT&T Inc. contributed to a broader trend of high debt activity in the European primary market. For context, one day in early 2026 saw over EUR 61 billion ($71.3 billion) of debt priced by at least 28 issuers across 42 tranches, marking a record for both volume and the number of individual tranches on sale. AT&T's activity, particularly across euros and sterling, aligns with companies taking advantage of robust market conditions to secure financing.
