On July 28, AT&T Inc rose 3.07% in regular trading, trading at $25.12/share, with turnover of $364 million. The stock was buoyed by dual catalysts: an expanded quantum computing collaboration with D-Wave Quantum and residual momentum from its better-than-expected Q2 results.

AT&T and D-Wave Quantum announced an expanded agreement to further integrate D-Wave's quantum annealing technology into AT&T's network operations, specifically to support its agentic AI solutions. In prior collaboration phases, AT&T leveraged the technology to compress network workload processing times from approximately one hour to under 15 seconds. AT&T also noted its intelligent agent tools helped reduce customer service disruption time by approximately 12 million hours.

Additionally, AT&T's Q2 earnings reported on July 22 showed adjusted EPS of $0.65, beating the consensus estimate of $0.59 by over 10%. Postpaid phone net additions reached 432,000, significantly exceeding the 338,500 analyst forecast. Consolidated revenue rose 2.3% year-over-year to $31.6 billion, while adjusted EBITDA grew 5.2% to $12.3 billion. The company reiterated full-year adjusted EPS guidance of $2.25 to $2.35 and announced accelerated share buybacks.
