The Amdocs (DOX) Investor Investigation Overview:

The investigation stems from disclosures made by Amdocs on November 3, 2026, when the company reported its fourth-quarter and full-year fiscal 2026 financial results.

Amdocs revealed for the first time that it and its major client, T-Mobile USA, had exchanged formal legal notices alleging material breaches under their software and services agreements. According to public disclosures, both parties have threatened contract termination, monetary damages, and potential arbitration.

As a direct result of the escalating contractual dispute and pulled-back discretionary spending from T-Mobile, Amdocs drastically lowered its fiscal year 2027 guidance:

• Revenue Decline: Amdocs guided fiscal 2027 revenue down 14.3% to 17.9% year-over-year.
• Earnings Cut: Non-GAAP diluted earnings per share (EPS) are projected to plunge 26% to 30%.
• Backlog Contraction: Pro forma 12-month order backlog fell 9.6% to $3.5 billion, primarily driven by T-Mobile contract adjustments.
  

Management acknowledged on its earnings call that its conservative guidance incorporates a full termination scenario of the T-Mobile contracts. Following these revelations, Amdocs stock plummeted during intraday trading on November 4, 2026, erasing billions of dollars in shareholder value.

Focus of Hagens Berman's Legal Inquiry

Earlier in February 2026, Amdocs publicly touted a major, multi-year strategic agreement expansion with T-Mobile, presenting the relationship as a long-term growth driver across managed services and system integrations. Hagens Berman's investigation focuses on whether Amdocs leadership knew of escalating operational breakdowns, default notices, or material breaches prior to November 3, 2026.
“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 firm’s investigation.
