Equity capital markets analyst

Insider files to sell 132,000 Amphenol shares after option exercise.

An Amphenol common shareholder has notified plans to sell 132,000 shares through Morgan Stanley Smith Barney LLC on or about 12/02/2025. These shares come from an option exercise under a registered plan, paid in cash, which indicates this is a routine liquidity event tied to equity compensation rather than a new issuance by the company.

The notice also reports that the same person, named as Peter John Straub, sold 88,000 common shares on 09/08/2025 for gross proceeds of $9,735,941.60. With Amphenol common shares outstanding of 1,224,055,508, the combined 220,000 shares referenced represent a small fraction of the company’s equity base. The impact on overall share supply therefore appears limited based on the figures disclosed.

The signer represents that they do not know any material adverse, nonpublic information about Amphenol’s current or prospective operations. This representation is standard for such sales and is reinforced by the reminder that intentional misstatements can constitute federal criminal violations.
