Is Aptiv Plc overvalued or undervalued?

As of 17 October 2025, Aptiv Plc's valuation grade has moved from attractive to fair, indicating a shift in its perceived value. The company appears to be fairly valued at this time. Key valuation ratios include a P/E ratio of 8.26, an EV/EBITDA of 7.57, and a PEG ratio of 0.0, which suggests that while the company is not overvalued, it also lacks growth prospects compared to its peers.
In comparison to its industry, Aptiv's P/E ratio is relatively low, indicating that it may be undervalued compared to similar companies. For instance, if we look at peers like Company A with a P/E of 10 and Company B with a P/E of 12, Aptiv's lower ratio might suggest it is a more attractive investment, albeit with limited growth potential. Notably, over the past year, Aptiv has returned 18.40%, outperforming the S&P 500's return of 14.08%, which may reinforce the narrative of its fair valuation amidst a competitive market.
