Phillips 66 Refining Chief Richard Harbison Gives Notice He Will Retire December 31, 8-K Says
The 8-K names no successor for the executive vice president of refining and gives no reason for the retirement.
Richard G. Harbison, Phillips 66's executive vice president of refining, told the company he intends to retire, effective December 31, 2026, according to an 8-K filed Monday. He gave notice on Tuesday, September 29.
What the 8-K says
The filing falls under Item 5.02, the section public companies use to report departures of directors and certain officers. It contains one operative sentence: Harbison, Executive Vice President, Refining, gave the company notice that he intends to retire, with the retirement effective December 31, 2026.
The filing offers no reason beyond that notice. It does not name a successor or say how the refining role will be handled. Vanessa A. Sutherland, an executive vice president at Phillips 66, signed the report, dated October 5, 2026.
What it changes
Refining leadership at Phillips 66 will be open at year-end, and the filing does not say who will fill it. Holders have no replacement to assess yet.
The stock closed at $264.58 on Friday, up 0.13%, a session that came before the Monday disclosure (market data). That figure is not a reaction to the news.
What to watch
Harbison's retirement takes effect December 31, so the company would need to name who leads refining by then. A follow-up filing or announcement would be the place to find out.
The filing sets one firm date, December 31, 2026, and leaves the successor question unanswered.
