The company has demonstrated its ability to substantially recoup tariff-related costs from customers, including commercial vehicle OEMs, due to strong customer relationships and a clear value proposition. This regionalization strategy contrasts with competitors who might have more complex global supply chains, potentially exposing them to greater tariff impacts.

Financial Performance and Capital Allocation

PHINIA has demonstrated solid financial performance, particularly in its third quarter of 2025, which marked the first period of fully comparable year-over-year results since the spin-off. Net sales for the three months ended September 30, 2025, increased by 8% to $908 million, driven by volume, customer pricing, tariff recoveries, and the SEM acquisition. Gross profit for the quarter rose to $200 million. Adjusted EBITDA reached a record $133 million, with a margin of 14.6%, representing a 30 basis point year-over-year expansion, primarily due to lower R&D expenses and strong performance in the Fuel Systems segment. Adjusted earnings per diluted share for Q3 2025 were $1.59, up from $1.17 in the prior year.

For the nine months ended September 30, 2025, net sales totaled $2,594 million, a 1% increase year-over-year, with net earnings of $85 million. The Fuel Systems segment reported sales of $1,559 million and an Adjusted Operating Income (AOI) margin of 11.5%, an increase of 90 basis points year-over-year, driven by R&D savings and overhead cost control. The Aftermarket segment generated sales of $1,035 million with an AOI margin of 15.7%.

PHINIA maintains a robust balance sheet and strong liquidity. As of September 30, 2025, the company had $848 million in total liquidity, comprising $349 million in cash and cash equivalents and $499 million available under its revolving credit facility. The net leverage ratio stood at a healthy 1.4x, below its target of approximately 1.5x. The company's adjusted free cash flow has been strong, reaching $104 million in Q3 2025. This financial strength enables a disciplined capital allocation strategy, including returning capital to shareholders. In Q3 2025 alone, PHINIA returned $41 million through dividends and share repurchases, with $194 million remaining under its current repurchase authorization.

A notable event was the October 15, 2025, settlement agreement with its former parent, BorgWarner Inc., resolving previously disclosed claims. While this resulted in a $39 million loss recognized in Q3 2025, a substantial portion of the settlement payments is expected to be offset by indirect tax refunds and the utilization of pre-spin-off tax credits, potentially yielding up to $29 million in cash by the end of 2026. This resolution clarifies tax liabilities and enhances PHINIA's financial flexibility.
