Elliott Investment Management has taken a significant stake in Honeywell International, valued at over $5 billion, marking its largest investment in a single stock to date. The activist investor is urging Honeywell to split into two separate entities focusing on aerospace and automation, citing underperformance compared to peers and a convoluted corporate structure. Elliott argues that such a breakup could enhance value by up to 75% over two years and enable each division to thrive independently. The proposal comes amidst Honeywell's recent strategic shift under CEO Vimal Kapur towards emerging trends like automation and energy transition, though Elliott notes the company has struggled to meet performance expectations. Honeywell's shares rose following Elliott's announcement, and the company has expressed openness to discussions with the investor. This move aligns with a broader trend of industrial conglomerates like GE and United Technologies opting for similar breakups to unlock shareholder value.
