What could go wrong and has it survived trouble before?

Insider activity: Net selling for 8 consecutive quarters through Q1'26, with selling in 12 of 20 quarters
Resilience grade: 'A' rating with recovery from major shocks typically within 1 quarter
Worst performance: FCF turned negative -$300 million in Q1'24 despite positive operating income
