Approach 1: Allison Transmission Holdings Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a stock could be worth by projecting future cash flows and discounting them back to today using a required return. It essentially asks what all those future dollars are worth in today's terms.

For Allison Transmission Holdings, the model uses a 2 Stage Free Cash Flow to Equity approach. The latest twelve month free cash flow is about $637.6 million. Analysts provide explicit free cash flow estimates for the next few years, and Simply Wall St then extends those projections out to 2035. For example, projected free cash flow in 2030 is $1,220 million, with intermediate years between 2026 and 2035 ranging from about $709.7 million to $1,419.3 million before discounting.

When all of these projected cash flows are discounted back and summed, the DCF model arrives at an estimated intrinsic value of about $205.65 per share. Compared with the current share price of roughly $118, this implies the stock is 42.4% undervalued according to this framework.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Allison Transmission Holdings is undervalued by 42.4%. Track this in your watchlist or portfolio, or discover 47 more high quality undervalued stocks.

Approach 2: Allison Transmission Holdings Price vs Earnings

For a profitable company, the P/E ratio is a straightforward way to connect what you pay for the stock with what the business is currently earning. It tells you how many dollars investors are willing to pay today for each dollar of earnings.

What counts as a “normal” P/E depends on how the market views the company’s growth prospects and risk profile. Higher growth and lower perceived risk tend to support a higher P/E, while slower growth or higher risk usually line up with a lower multiple.

Allison Transmission Holdings currently trades on a P/E of 18.08x. That sits below the Machinery industry average of 26.85x and a peer group average of 30.96x. Simply Wall St also calculates a proprietary “Fair Ratio” of 27.26x for Allison Transmission Holdings. This Fair Ratio estimates the P/E that might be expected given factors such as earnings growth, profit margins, industry, market cap and company specific risks.

Because it adjusts for these company characteristics, the Fair Ratio can offer a more tailored reference point than a simple comparison with industry or peer averages. With the actual P/E of 18.08x sitting below the Fair Ratio of 27.26x, the stock screens as undervalued on this measure.

Result: UNDERVALUED
