Honeywell International Inc. will split into separate publicly traded companies following pressure from an activist investor, the latest in a line of industrial conglomerates seeking a more streamlined portfolio.

Honeywell is splitting into three independently listed companies, breaking up one of America's last standing conglomerates just months after activist investor Elliott Management took a $5 billion stake in the industrial giant.

Honeywell said it will split into three companies. The aerospace giant said it will separate its aerospace, automation and advanced materials units into distinct entities in 2026.
