D-Wave Quantum Inc.

Item 7.01 Regulation FD Disclosure. On July 27, 2026, D-Wave Quantum Inc. (“D-Wave”) announced that AT&T has signed an agreement to expand its use of D-Wave's quantum computing technology and plans to use the technology to address complex optimization challenges across its network operations. AT&T's initial focus is on layering D-Wave's annealing quantum computing technology into the tools that are already powering AT&T’s agentic AI solutions. Agentic tools in AT&T’s network are improving network operations like outage detection and management, reducing customer downtime by 12 million hours in 2025. New quantum capabilities could help increase the benefits of agents in AT&T’s network operations. AT&T is also evaluating D-Wave's forthcoming gate-model systems for potential applications in quantum security and quantum communications. This agreement is part of AT&T's broader innovation strategy, which applies quantum computing, AI, automation, advanced analytics, and software-defined infrastructure to modernize how the network is built, run, and optimized. A copy of the press release is attached as Exhibit 99.1. The information in this Item 7.01 to this Current Report on Form 8-K, including Exhibit 99.1, is intended to be furnished and shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall such information be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such a filing.
