Amphenol told its management team on October 1 that Ryan Fisher will [take over as president](https://www.sec.gov/Archives/edgar/data/0000820313/000110465926114035/tm2627036d1%5F8k.htm?ref=bullished.co) of its Harsh Environment Solutions Division on January 1, 2027, according to an 8-K the company signed Tuesday. Luc Walter, who now runs the division, moves to a new role the same day after 43 years with the company.

## What the 8-K says

The filing is an [Item 5.02 report](https://www.sec.gov/Archives/edgar/data/0000820313/000110465926114035/tm2627036d1%5F8k.htm?ref=bullished.co), the section companies use to disclose changes among certain officers. It says Amphenol notified its management team on October 1, 2026 of the move.

Walter, currently President of the Harsh Environment Solutions Division, will become Senior Vice President, Strategic Programs, effective January 1, 2027\. The filing says he is making the transition ["after 43 years with the Company."](https://www.sec.gov/Archives/edgar/data/0000820313/000110465926114035/tm2627036d1%5F8k.htm?ref=bullished.co)

Fisher is currently Group General Manager of the company's North American Military Group. He will succeed Walter as division president beginning January 1, 2027.

The report was signed by Lance E. D'Amico, Amphenol's Executive Vice President, Secretary and General Counsel.

## What it changes

Leadership of the division passes from a 43-year company veteran to an executive who currently manages a military-focused group inside Amphenol. The filing does not say whether Fisher's current group role will be filled or by whom.

The filing does not describe a departure, and it gives no reason for the change. Walter stays with the company in a different title.

It includes no financial terms, pay details or guidance changes. Shares of Amphenol were up 0.06% at $88.67 in Tuesday after-hours trading, versus a regular close of $88.62 (market data).

## What to watch

The handover takes effect January 1, 2027, when Fisher assumes the division presidency and Walter starts as Senior Vice President, Strategic Programs.

The next date that matters is January 1, 2027, when both changes take effect.
