AI Summary

7.0
Positive

APH is an AI-infrastructure connectivity compounder—not a traditional connector supplier—with exceptional 63% AI/datacom organic growth and expanding margins, but its premium valuation and higher leverage leave little room for a hyperscaler-capex slowdown or acquisition missteps; favor entry only if AI demand and support near $77 hold.
