Amphenol Corporation (APH) — ESG & Values Scores

Environment story

Amphenol has disclosed a sustainability report and established climate-related governance oversight through the Audit Committee, demonstrating commitment to environmental accountability. However, the company has not disclosed specific Scope 1, 2, or 3 emissions figures in the available filings, nor has it published a quantified net-zero target year. The company states operations are in substantial compliance with environmental laws and participates in ISO14001 and ISO50001 certifications at approximately half its facilities. The company acknowledges climate risks including extreme weather impacts on supply chain and manufacturing, and faces potential future climate regulation costs. Without disclosed emissions baselines and concrete decarbonization targets, the environmental score reflects moderate performance with significant uncertainty and room for improvement in transparency.

Social story

Amphenol demonstrates moderate social performance with a global workforce of approximately 170,000 employees (90% outside the United States) and structured human capital management oversight. The company explicitly states less than 10% of its U.S. workforce is unionized and reports good relationships with both unionized and non-unionized employees. The company emphasizes diversity in its communities and local management accountability. However, the proxy and 10-K do not disclose CEO-to-median-worker pay ratio, diversity percentages (executive/board/workforce), or detailed supply-chain labor audit results. The company has not disclosed documented union-suppression activities or major strikes in the past 24 months. Limited transparency on diversity metrics and supply-chain labor practices constrains the social score.

Governance story

Amphenol demonstrates strong governance with 7 of 8 directors independent (87.5% board independence), exceeding the 75% threshold. The company has transitioned to a combined Chairman/CEO structure with a Lead Independent Director (David P. Falck) to ensure independent oversight. Board composition includes diverse skills in finance, strategy, M&A, environmental matters and talent development. All directors attended 100% of meetings in 2025 (except two missing one special meeting). The company maintains a clawback policy, insider trading compliance policy, and stock ownership guidelines. However, the company does not disclose annual lobbying expenditures or PAC contributions, making assessment of political alignment impossible. One significant governance risk is the $100 million tax charge related to challenged Chinese tax positions over an eight-year period, with potential liability up to $300 million, indicating material tax governance and compliance risks. The company is subject to complex export controls and government contracting regulations given its 9% defense market exposure.
