Approach 1: Phillips 66 Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model looks at the cash Phillips 66 is expected to generate in the future and then discounts those amounts back to today, giving an estimate of what the whole business could be worth right now.

For Phillips 66, the model uses a 2 Stage Free Cash Flow to Equity approach based on cash flow projections. The latest twelve month Free Cash Flow is about $3.0b. Analyst estimates and Simply Wall St extrapolations point to projected Free Cash Flow of $7.4b in 2030, with detailed projections each year from 2026 through 2035. These cash flows are all discounted back to today using this model.

Based on these cash flows, the DCF model suggests an estimated intrinsic value of around $402.75 per share. Compared with a current share price of about $174.70, this implies the stock is 56.6% undervalued according to this cash flow based approach.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Phillips 66 is undervalued by 56.6%. Track this in your watchlist or portfolio, or discover 61 more high quality undervalued stocks.

Approach 2: Phillips 66 Price vs Earnings

For profitable companies, the P/E ratio is a straightforward way to link what you pay for each share to the earnings that support it, which is why it is a common starting point for many investors.

What counts as a “normal” P/E often reflects how the market views a company’s earnings growth potential and risk profile. Higher growth or lower perceived risk usually matches with a higher multiple, and the reverse holds for slower growth or higher risk.

Phillips 66 is currently trading on a P/E of 15.94x. That is close to the Oil and Gas industry average P/E of 15.66x and below the 24.53x peer average included in this dataset, which suggests peers as a group trade on a higher earnings multiple.

Simply Wall St also calculates a “Fair Ratio” for Phillips 66 of 23.44x. This proprietary metric estimates the P/E that might be reasonable given factors such as earnings growth, industry, profit margin, company size and specific risks. This makes it more tailored than a simple comparison against peers or the broad industry.

Comparing the Fair Ratio of 23.44x with the current P/E of 15.94x indicates that the shares screen as undervalued on this earnings based approach.

Result: UNDERVALUED
