[Hagens Berman](https://akta.pro/company-profiles/00034xb/hagens-berman) is investigating [Amdocs](https://akta.pro/company-profiles/0004gw7/amdocs) Limited for potential federal securities law violations tied to the company's contract dispute with [T-Mobile](https://akta.pro/company-profiles/00000pm/t-mobile) USA, the firm said in a [GlobeNewswire release](https://www.globenewswire.com/news-release/2026/11/04/3395741/32716/en/hagens-berman-national-securities-law-firm-investigating-amdocs-limited-nasdaq-dox-following-escalating-t-mobile-contract-dispute-and-stock-collapse-hbss.html) on November 4, 2026. The inquiry centers on whether Amdocs executives made false or misleading statements about the stability of its relationship with its key customer. ## Hagens Berman's Amdocs Inquiry Amdocs disclosed on November 3, 2026, in its fourth-quarter and full-year fiscal 2026 results, that it and T-Mobile had exchanged formal legal notices alleging material breaches under their software and services agreements. Both parties have threatened contract termination, monetary damages and potential arbitration, according to the release. Amdocs guided fiscal 2027 revenue down 14.3% to 17.9% year over year and projected non-GAAP diluted earnings per share to fall 26% to 30%. Pro forma 12-month order backlog fell 9.6% to $3.5 billion, driven primarily by T-Mobile contract adjustments. Management said on its earnings call that the conservative guidance incorporates a full termination scenario of the T-Mobile contracts. Hagens Berman's investigation focuses on whether Amdocs leadership knew of operational breakdowns, default notices or material breaches before November 3, 2026, after the company in February 2026 touted a multi-year strategic agreement expansion with T-Mobile. "We're evaluating whether Amdocs misled the market by potentially omitting to disclose contract strain and breach allegations with its most significant customer while maintaining its financial projections," said Reed Kathrein, the Hagens Berman partner leading the investigation.
