HVAC service revenue spotlighted as UK issues air-conditioning health warnings

Johnson Controls International fell 5.5% to $114.79 in afternoon trading on Tuesday after Nvidia CEO Jensen Huang said the chipmaker’s next-generation Vera Rubin platform could sharply reduce cooling needs in data centers and that “no water chillers are necessary for data centres.” The stock has traded between $108.41 and $120.39, and other heating, ventilation and air-conditioning names also weakened. Barclays analysts led by Julian Mitchell said investors “should not take their comments lightly” and estimated data centers account for a low-double-digit share of Johnson Controls’ sales. Reuters
