Operational Shutdown at Uponor, Global Intelligent Plumbing and Climate Solutions provider

March 27, 2023


On 5 November 2022, Uponor was subject to a ransomware attack, which impacted its operations in Europe and North America.

Uponor announced in its press release on 18 November 2022, the company’s operations are still affected by the ransomware attack that occurred on 5 November. After the attack, the company took immediate actions to investigate and remediate the situation. One of these actions was to shut down all systems and production as a precautionary measure. After one week of production shutdown, operating levels have started to recover, and customer deliveries have restarted in all divisions during the past week. Uponor’s current focus lies on accelerating operational performance back to the operating levels before the attack while protecting the company’s systems.

As the attack happened close to the end of the year, the ability to cover lost sales during 2022 remains uncertain. Therefore, Uponor is withdrawing its guidance for 2022 until there is better visibility on operational ramp up and sales coverage.
