What this company does
Amphenol designs and manufactures electrical connectors, cables, sensors, and antennas used in everything from data centers and smartphones to cars, jets, and military hardware. It generates revenue by selling these interconnect components to OEMs across IT, communications, automotive, industrial, defense, and mobile end markets. Sales surged 53% year-over-year to $6.2 billion in Q3 2025, driven by booming AI data center demand and a $2.8 billion acquisition spree that expanded goodwill to nearly $9.9 billion.

Key risks
- Acquisition-driven balance sheet expansion: goodwill jumped to $9.87B and intangibles to $1.98B after $2.77B of YTD deals, raising integration and impairment risk.
- Rising leverage: total debt reached ~$8.07B with $937.6M current; interest expense up 59% YoY to $238.1M for nine months.
- Working capital strain: receivables surged 38% to $4.54B and inventories 30% to $3.30B, consuming $435M cash and signaling potential demand normalization.
