Form SCHEDULE 13D/A CARRIER GLOBAL Corp Filed by: Viessmann Generations Group GmbH & Co. KG

On May 20, 2026, Viessmann Traeger HoldCo GmbH (together with its affiliates, "VGG") entered into a block trade (the "Block Trade") with JPMorgan Chase Bank, N.A. ("JPMorgan") with respect to a portion of VGG's ownership of Carrier Global Corporation ("Carrier" or the "Company") common stock. The aggregate number of shares sold in the Block Trade was 12,094,823. The price of the shares sold in the Block Trade represents a discount of 2.4847% to the closing price of Carrier's common stock on May 20, 2026. VGG received the Carrier shares as consideration for Carrier's acquisition of Viessmann Climate Solutions in January 2024. VGG entered into the Block Trade to support portfolio rebalancing. Notwithstanding the Block Trade, VGG continues to hold a substantial ownership position in the Company and remains one of the Company's largest shareholders. Max Viessmann remains firmly committed to Carrier for the long term, as demonstrated by his substantial investment in the Company and his sustained focus on advancing its growth strategy and value creation framework. Mr. Viessmann believes that his investment in Carrier positions VGG to participate in the Company's long-term growth and supports the Company's competitiveness over the short-term and long-term. As further evidence of Mr. Viessmann's belief in Carrier and its future, he will proudly continue to serve on the Company's Board of Directors and will assume the role of Chair of the Company's Technology & Innovation Committee. In that capacity, Mr. Viessmann expects to devote even further time and attention to the Company and its strategic priorities. Mr. Viessmann added: "Carrier and Viessmann Climate Solutions together represent a unique platform to accelerate innovation and drive the energy transition. I remain fully committed to Carrier and its long-term success. I look forward to taking on the role of Chair of the Technology & Innovation Committee to support the Company's strategic growth initiatives and long-term competitiveness."
