Analog Devices, one of the world’s largest analog semiconductor companies, has disclosed a data breach in a filing with the U.S. Securities and Exchange Commission. The company says an unauthorized party accessed certain systems and exfiltrated files on June 23, 2026. Analog Devices activated its incident response plan immediately and brought in external cybersecurity experts to contain the breach and investigate its scope. The company reports that operations are currently unaffected, though it has not disclosed what type of data was compromised or whether customer, employee, or intellectual property data was taken.
Analog Devices is a major supplier of chips for industrial automation, automotive systems, communications infrastructure, healthcare equipment, aerospace, and data centers. The company employs around 24,500 people and posted over $11 billion in revenue in 2025. The breach has not been attributed to any known threat actor, and the investigation is ongoing. An SEC disclosure is required when a publicly traded company determines a cybersecurity incident is material — Analog Devices’ filing signals the company has assessed this breach as potentially significant to investors.
