One strong refining quarter brings Phillips 66 close to its 2027 debt goal

Refining, which turns crude oil into petrol, diesel and jet fuel, has earned most of Phillips 66's money this year, and in the September 2026 quarter it earned enough to reshape the balance sheet. The margin its refineries realized on each barrel rose by more than half from the quarter before, and refining supplied about 85% of the company's adjusted pre-tax income. Net debt, which is borrowings minus cash, fell by $3.8 billion in three months, to $12.7 billion.

That puts the company well ahead of the path it laid out this year. In April, with debt swollen at the end of March, management guided to total debt of about $19 billion by the end of this year and $17 billion by the end of 2027. In August it added a year-end goal for net debt, which the company has now beaten by a wide margin. Total debt at the end of September was already below the year-end guide. Kevin Mitchell, the chief financial officer, said that after a bond repaid in October the company has "a comfortable path to hitting that $17 billion target."

Not all of that improvement is debt paid back. Borrowings fell by a little more than half the amount, and the rest is a larger cash balance, so on the reported figures nearly half of the fall in net debt is money kept rather than repaid. That looks deliberate. Mitchell said the company may strengthen its balance sheet by carrying more cash while it keeps returning half of its cash flow to shareholders.

The money came from one place. Refining's adjusted pre-tax income rose sharply from the quarter before, while midstream, chemicals, marketing and renewable fuels each earned less. The company put the refining gain down mainly to higher realized margins and volumes, and the margins mostly to wider crack spreads, the gap between what crude costs and what fuels sell for, a market price it does not set. Comparisons with a year earlier flatter the segment, because refining has carried all of the Borger and Wood River refineries only since Phillips 66 bought out its partner in WRB last autumn.

With the debt goals close, the open matter is where the cash goes next. Share repurchases rose to $2.3 billion, about six times the quarter before, as management had said in August they would. With dividends, the company returned a little under half of its operating cash flow before working-capital swings, calculated from the reported figures, against a stated aim of more than half. Mitchell put the share returned so far this year at 40% and said the final three months need to exceed 50% to bring the year to that level. He also said he did not want all surplus cash to go automatically into buybacks. Some of the quarter's cash will not recur: working capital added to it, and Mitchell said income tax accrued on the quarter's large profits had not yet been paid.

The dividend is the longer-term claim, and management ties it to a different business. Its latest increase leaves it 10.8% above the level of the end of last year, and Mitchell said high single-digit growth in the per-share dividend is a reasonable assumption. He rests that on midstream, the pipelines and gas plants he described as producing about $4 billion of EBITDA (earnings before interest, tax, depreciation and amortisation) a year and growing about 5%. On the filed numbers, that growth has not arrived this year: midstream adjusted pre-tax income for the first nine months was slightly below a year earlier, and its adjusted EBITDA slipped from the quarter before.

The additions are scheduled rather than delivered. The expanded Coastal Bend pipeline is due to send its first volumes before the year ends and reach full rates early next year, and the company has committed to the Western Gateway pipeline, due in service in 2029, for which Mitchell put Phillips 66's share of the cost at $2.5 billion. One quarter of strong refining margins has settled most of the debt question the company set itself, and left buybacks, a cash buffer, a pipeline bill and a growing dividend competing for what the refineries earn next.
