SLB shares rallied during the regular session, significantly outperforming its peers in the oil and gas equipment and services sector. The primary catalyst was the company's announcement, made overnight on August 31, that it has entered into a definitive agreement to acquire thermal management and heat-exchange technology provider Kelvion for $4.1 billion. This strategic move is designed to bolster SLB's data center solutions business, a diversification effort that investors viewed favorably alongside broader positive momentum in the energy sector.
