Phinia (PHIN) Q3 2026 earnings review
Phinia raises its full-year plan, but an acquisition drives it
Phinia's replacement-parts business and share buybacks lifted profit per share even as total revenue stood still. The maker of Delphi and Delco Remy engine parts reported $912 million in sales, as tariff refunds returned to customers hid a $21 million gain in the core business. Chief executive Brady Ericson raised the full-year outlook, and buybacks pushed profit per share excluding one-offs up 15%.
| Core business sales (ex-FX and tariffs) | +$21M +2.3% from a year ago by our math |
|---|---|
| Reported net sales | $912M +0.4% from a year ago |
| Profit per share, excluding one-offs | $1.83 +15% from a year ago |
| Full-year sales outlook | Raised $35M includes stoba acquisition in Q4 |
⚖️ Verdict: ⚪ Neutral
The story is unchanged because the higher full-year outlook comes from adding a newly acquired company rather than faster underlying growth. Phinia closed its purchase of German parts maker stoba Group on October 1 and folded stoba's fourth-quarter results into the plan, which by our math accounts for nearly all of the $35 million sales raise. One caution: unpaid customer bills and tax payments cut free cash flow by nearly a third.
The question now is whether Phinia's core engine-parts business is holding its profit margins as pricing tailwinds fade and new programmes ramp up. One view is that supply-chain savings and new industrial awards will lift margins; the other is that recent profit gains rely on tariff timing. The segment profit table and stoba breakdown in the quarterly filing will settle it.
🐂 Bull Case
Aftermarket Sales Carry the Quarter
Chief executive Brady Ericson said the results reflect "stable end market demand, continued aftermarket momentum, and strong financial discipline". While total revenue barely moved at $912 million, the company's Aftermarket Solutions division—which sells replacement parts for vehicle repair—grew 4.2% to $351 million on higher demand in the Americas.
The headline revenue figure also hid underlying growth because Phinia returned tariff refunds to customers, which reduced reported sales. Stripping out currency swings and those tariff adjustments, core business sales rose by $21 million, or 2.3% by our math, matching the pace of the first half.
What to watch: the exact revenue bridge in the quarterly filing. That table will show how much of the $21 million core gain came from volume versus price.
Buybacks Turn 8% Profit Growth Into 15% Per Share
Phinia continues to retire its own stock at a steady clip, even while funding an acquisition. The auto-parts supplier spent $65 million on share buybacks and $11 million on dividends during the third quarter, returning 104% of its cash flow after capital spending to shareholders.
Those repurchases lowered the diluted share count by 6.3% from a year ago, to 37.1 million shares. Because the share count shrank, net earnings excluding one-offs rose 15.1% per share to $1.83, nearly double the 7.9% growth rate of the $68 million profit pool itself.
What to watch: fourth-quarter buyback spending after the October 1 acquisition payment. A slower pace would mean the deal is competing with share repurchases for cash.
New Alternative Fuel and Global Wins
Phinia makes fuel and electrical systems for combustion engines, so its long-term health depends on winning business in alternative fuels and industrial markets. This quarter the company won its first methanol engine programme for industrial off-highway machines in China and a compressed natural gas injector programme for passenger cars in India.
In North America, the supplier also won a gasoline direct injection (GDI) pump contract for a range-extender vehicle, where a small combustion engine charges a battery. These awards show automakers still buy Phinia's parts for hybrids and lower-carbon fuels.
What to watch: the annual revenue breakdown by end market in the full-year report. A rise in the industrial and off-highway share above last year's 6% would prove these wins are moving the needle.
🐻 Bear Case
The Outlook Raise Comes From an Acquisition
Ericson said Phinia updated its full-year plan based on "solid third quarter results and the continued business momentum". The company raised the middle of its full-year sales outlook by $35 million, to $3.65 billion, and lifted its target for adjusted EBITDA—earnings before interest, taxes, depreciation and amortization, excluding one-offs—by $10 million, to $510 million.
However, a footnote notes that "Updated guidance includes the expected fourth-quarter contribution from the recent acquisition of the stoba Group, which closed on October 1, 2026". Last quarter, Phinia said stoba—a German maker of precision metal parts—brings about $80 million in annual outside sales and $25 million in adjusted EBITDA, or roughly $20 million and $6 million per quarter.
By our math, the new plan implies $920 million of fourth-quarter sales, up 3.5% from a year ago. Without stoba's roughly $20 million contribution, implied fourth-quarter sales growth is just 1.2%, meaning the existing business barely accelerated.
What to watch: stoba's exact fourth-quarter revenue and profit contribution in the full-year filing. That disclosure will show whether the legacy business grew at all in the final quarter.
Power Systems Shrinks as Pricing Fades
Phinia's largest division is Power Systems, formerly called Fuel Systems, which sells components directly to vehicle and machinery manufacturers. After growing 5% in the second quarter, Power Systems sales fell 1.8% from a year ago to $561 million.
The company blamed the drop on the timing of tariff recoveries and the absence of one-time customer price increases that boosted the prior year. The division also lapped the August 2025 purchase of Swedish Electromagnet Invest (SEM), a maker of natural-gas ignition systems, which had added to reported growth for four quarters.
What to watch: Power Systems segment operating margin in the quarterly filing. A drop from last quarter's 11.0% would show that new programme launches in Europe and Asia are still dragging on profitability.
Unpaid Customer Bills Weigh on Cash Flow
Cash generated by operating activities dropped by $32 million from a year ago to $87 million, and adjusted free cash flow fell $31 million to $73 million. Phinia said the decline was "primary due to withholding tax payments related to cash repatriation and an unfavorable working capital impact".
Accounts receivable—money customers owe for goods already delivered—rose to $902 million, up $98 million since December, "reflecting the timing of customer collections and higher receivable balances at quarter-end". Even after raising the full-year cash flow target by $5 million at the middle of the range, the plan implies just $46 million in the fourth quarter, down 49% from a year ago by our math.
What to watch: accounts receivable at year-end. A drop back toward $800 million would confirm the third-quarter cash drain was only collection timing.
Risks this quarter didn't answer
Four standing concerns from prior quarters could not be tested because the press release omits segment profit tables, end-market splits and footnote details.
- Power Systems margin drag from new launches: segment operating profit is not in the release; the quarterly filing's segment note will show if margins recovered from 11.0%.
- Sizing the industrial and aerospace growth engine: management announced a China methanol win but still gives no revenue figure for this end market.
- China light-vehicle and global commercial-vehicle demand: regional volume trends were not quantified in the release; the conference call and filing will provide the read.
- Ford fuel-pump recall: the release gives no update on the 850,000-vehicle recall; the warranty footnote in the quarterly filing will show if accruals moved.

Tariff Refund Timing Swings Revenue and Margin
Trade-tariff adjustments moved Phinia's revenue and profit in opposite directions this quarter. Returning tariff refunds to customers reduced reported net sales compared with a year ago, when the company was billing customers to recover tariff costs. At the same time, the favourable timing of those tariff mechanisms lifted the adjusted EBITDA margin by 0.2 percentage points to 14.8%, offsetting higher research and development spending.
💲 Other KPIs
Capital spending including tooling outlays fell to $17 million, or 1.9% of sales by our math, down from $26 million a year ago. Over the first nine months, the supplier spent $71 million (2.6% of sales), staying well below its long-term ceiling of 4% of sales and supporting free cash flow.
Total debt less cash rose to $657 million from $611 million at the end of 2025. Phinia added $73 million in short-term borrowings during the quarter, building cash to $436 million ahead of the October 1 closing of the stoba acquisition. Net debt stands at 1.3 times trailing adjusted EBITDA, below the 1.5x target.
Overhead, selling and research costs rose to $111 million, or 12.2% of sales by our math, up from $105 million (11.6% of sales) a year ago. Ericson noted that profit grew "despite higher R&D spending and investments in customer relationships", while gross margin improved by 0.4 percentage points to 22.4%.
🔮 Guidance
Raised. The middle of the range moved up $35 million to $3.65 billion, or 4.8% growth for the year, after holding at $3.615 billion for three straight quarters. The new range includes fourth-quarter sales from stoba Group, acquired on October 1. By our math, that leaves $920 million for the fourth quarter, up 3.5% from a year ago.
Raised. Management lifted the middle of the range by $3.5 million to $171 million, partially reversing last quarter's $12.5 million cut. With $144 million already earned in the first nine months, the plan leaves $27 million for the fourth quarter by our math, down 40% from $45 million in the prior-year period.
Raised. The middle of the target rose $10 million to $510 million, or 6.7% growth from 2025, helped by adding stoba for the fourth quarter. By our math, the outlook implies $130 million in the fourth quarter, up 12.1% from a year ago but down from $135 million this quarter.
Raised. The bottom of the range moved up 0.2 percentage points, putting the middle at 13.9% compared with 13.7% in 2025. By our math, the dollar midpoints imply a 14.1% margin in the fourth quarter, down from 14.8% in the third quarter but above the 13.0% recorded a year ago.
Raised. Phinia lifted the bottom of the range by $10 million, moving the middle up $5 million to $235 million. Because the company has already generated $189 million in the first nine months, the outlook implies just $46 million for the fourth quarter by our math, half of last year's $91 million.
Improved. Management lowered the expected tax rate excluding one-offs by 2.5 percentage points at the middle of the range, to 29%, down from 32.5% in 2025. This is the second straight quarter the company has reduced its full-year tax rate forecast as it cleans up its post-spin tax structure.
❓ Key Questions
How much does stoba add to the fourth-quarter outlook?
The full-year sales outlook rose by $35 million and adjusted EBITDA by $10 million at the middle of the range, but the new numbers include stoba from October 1. Without the exact fourth-quarter contribution from stoba, investors cannot tell if the legacy outlook was raised or cut.
Did Power Systems operating margins recover in the third quarter?
Management previously said margin pressure from new programme launches in Europe and Asia would fade over about a year. The press release omits segment operating profit, leaving open whether Power Systems improved from last quarter's 11.0% margin.
How much tariff refund cash has actually been collected?
Last quarter Phinia booked an $11 million profit benefit from estimated tariff refunds while collecting only $1 million in cash. This quarter receivables rose to $902 million and operating cash flow fell by $32 million, raising the question of when refund cash will arrive.
What is the current revenue of the off-highway and industrial business?
Phinia highlighted its first methanol engine award for off-highway machines in China as proof of its diversification strategy. However, the company has not updated the size of its off-highway, industrial and aerospace business since reporting it at 6% of sales for 2025.
