Ariel Focus Fund on PHINIA Inc.

Thesis

Ariel continues to favor PHINIA despite a quarter of mixed results and lower profitability guidance. Revenue and free cash generation remained solid, although margin pressure masked that strength. The investment case rests on diversified end markets, disciplined capital allocation and strong cash generation. Alternative fuels, aerospace and defense, and aftermarket sales offer potential growth beyond current earnings.

“we like PHINIA's diversified end markets, strong cash generation, disciplined capital allocation”
