Proxy Statement | 2025 | i

Dear Fellow Shareholders,

On behalf of our entire Board of Directors, thank you for your continued investment in PHINIA. Looking back on the past year, our Board is incredibly proud of the progress PHINIA and its employees made in our first full year as an independent company, and we believe the Company is well-positioned for the future. As directors, we take pride in the role we play in overseeing the Company's execution of our strategy and disciplined approach to capital allocation.

Delivering on Our Business Strategy

During 2024, our talented workforce, under the leadership of Brady Ericson, PHINIA's President and Chief Executive Officer, continued executing our strategy for long-term value creation and delivered solid financial and operational performance, despite macroeconomic headwinds and challenges. PHINIA's product leadership, customer service focus, and stable growth strategy led to several exciting new business wins across product lines and geographies and expansion into growing markets. This focus on execution translated into excellent 2024 financial results that gave our Board the ability to return significant capital to our shareholders. In 2024, we returned more than $256 million to shareholders through a combination of quarterly dividends and share repurchases. These returns were complemented by meaningful appreciation in the price of our common stock, with shares closing the year up more than 59% over the prior year-end.

Highly Engaged and Balanced Board

Our Board remains committed to robust oversight of the Company's long-term strategy. To support this commitment, we continually assess the composition of the Board to ensure we have the right mix of skills and perspectives. This process contributed to our decision, in June 2024, to welcome Meggan M. Walsh to our Board. Meggan brings extensive leadership experience in investment management and financial expertise, including in capital allocation and merger and acquisition analysis, and insight into investor expectations and stewardship matters, including capital allocation, disciplined investments, shareholder returns, and risk oversight.

Constructive and Proactive Shareholder Engagement

The Board and management value the opportunity to engage with our shareholders. Over the past year, our engagement focused on financial performance, corporate governance, executive compensation, industry dynamics and market trends, and sustainability matters, among others. The Board and management regularly discussed the feedback received during these meetings. Our discussions informed various decision making throughout the year, including as we assessed strategic decisions for the near and long term, and contributed to our decision to welcome Meggan to our Board.

Publishing Our Inaugural Sustainability Report

In August 2024, PHINIA published its inaugural sustainability report. Sustainability has long been embedded in PHINIA's business and culture, and the report highlights the steps the Company has taken to formalize its sustainability priorities and strategies. These initiatives are regularly discussed between the Board and management and include efforts to quantify and reduce emissions in new product development, optimize energy efficiency and reduce greenhouse gas emissions across our operations, accelerate talent development and engagement throughout our workforce, and continuously improve PHINIA quality and safety in our facilities and relating to our products.

Thank You

We are grateful for your support of PHINIA and the over 12,500 employees who further PHINIA's vision for a brighter, cleaner tomorrow and uphold its culture and values. Your vote and perspective are important to us. We encourage you to review both our proxy statement and annual report and hope you can join us at our 2025 Annual Meeting of Shareholders on May 21, 2025.

With respect and gratitude,

Rohan S. Weerasinghe

Independent, Non-Executive Chair

Cautionary Statement Regarding Forward-Looking Information

This Proxy Statement and Letter from Our Non-Executive Chair contain certain "forward-looking statements" within the meaning of U.S. federal securities laws. Forward-looking statements are statements other than historical fact that provide current expectations or forecasts of future events based on certain assumptions and are not guarantees of future performance. Forward-looking statements use words such as "anticipate," "believe," "continue," "could," "designed," "effect," "estimate," "evaluate," "expect," "forecast," "goal," "initiative," "intend," "likely," "may," "outlook," "plan," "potential," "predict," "project," "pursue," "seek," "should," "strive," "target," "when," "will," "would," or other words of similar meaning. Forward-looking statements are subject to risks, uncertainties, and factors relating to our business and operations, all of which are difficult to predict and which could cause our actual results to differ materially from the expectations expressed in or implied by such forward-looking statements. These risks, uncertainties, and other factors are described more fully in the Company's most recently filed Annual Report on Form 10-K for the fiscal year ended December 31, 2024 and subsequent filings with the SEC. We caution readers not to place undue reliance upon any such forward-looking statements, which speak only as of the date they are made. We undertake no obligation to publicly update forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by law.
