• Simply Wall St's valuation framework currently gives Aptiv a value score of 3 out of 6. Next we will walk through the key valuation approaches behind that score, and then finish with a way to pull those numbers together into a clearer big picture.

Approach 1: Aptiv Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a company might be worth today by projecting its future cash flows and discounting them back to a single present value figure.

For Aptiv, the latest twelve months Free Cash Flow is about $1.37b. Simply Wall St applies a 2 Stage Free Cash Flow to Equity model that uses analyst forecasts where available, then extends those cash flows further into the future using its own assumptions. Within that framework, Aptiv's projected Free Cash Flow for 2028 is $1.74b, and the model continues with additional projections out to 2035, all converted into today's dollars.

On this basis, the DCF model points to an estimated intrinsic value of about $129.91 per share. Against the recent share price of $79.72, this implies the stock is 38.6% undervalued according to these cash flow assumptions.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Aptiv is undervalued by 38.6%. Track this in your watchlist or portfolio, or discover 55 more high quality undervalued stocks.

Approach 2: Aptiv Price vs Earnings

For a profitable company like Aptiv, the P/E ratio is a useful way to see how much you are paying for each dollar of earnings. It connects directly to what the business is currently earning, which many investors find easier to relate to than cash flow models.

What counts as a "normal" or "fair" P/E depends on how the market views a company’s earnings growth prospects and risks. Higher growth or lower perceived risk can support a higher P/E, while slower growth or higher risk usually calls for a lower one.

Aptiv currently trades on a P/E of 104.40x. That is well above the Auto Components industry average of 24.30x and also above the broader peer group average of 28.61x. Simply Wall St’s Fair Ratio for Aptiv is 33.62x, which is its proprietary estimate of what a justified P/E might look like after accounting for factors such as earnings growth, profitability, risk profile, industry and market cap. This tailored Fair Ratio aims to be more informative than a simple comparison with peers or the industry alone, because it reflects Aptiv’s specific characteristics.

Comparing the Fair Ratio of 33.62x with the current P/E of 104.40x suggests Aptiv is trading above that fair range on an earnings basis.

Result: OVERVALUED
