The company's fiscal year revenue reached $15.22 billion, with net income of $2.42 billion, per TradingView data published in 2026.

Conclusion

Amphenol Corp's recent 4.3% drop to $122.47 on May 11, 2026, highlights short-term volatility amid a weekly decline, yet analyst consensus points to a $181.72 target price from 18 firms, implying substantial upside potential according to Marketscreener as of 2026.
