Honeywell Aerospace slashes 2026 guidance on supply chain constraints – critical upstream bottleneck for Boeing

Honeywell shares tank 26% after cutting 2026 organic sales growth forecast to 4-5% and EPS miss. Commercial OE revenue up only 6% despite higher production schedules, confirming upstream bottlenecks persist. J.P. Morgan sets Street-low target. Prolonged constraints threaten Boeing's 737/787 production ramp and margin recovery. Prioritization of OEM deliveries over aftermarket is a double-edged sword. Investors should watch impact on delivery targets and cost structure.
