Listen to the news
  • Wondering if Allison Transmission Holdings at around $95 a share is a bargain or a trap? You are not alone, and this breakdown is designed to help you decide if the current price still makes sense.
  • The stock has climbed 6.4% over the last week and 16.0% over the last month, but that sits against a tougher backdrop of a -11.7% return year to date and -15.5% over the last year, despite a 132.2% gain over 3 years and 147.1% over 5 years.

  • On our numbers Allison Transmission Holdings scores a solid 5 out of 6 on undervaluation checks. We will unpack this using multiple valuation approaches, and we will finish by looking at a more intuitive way to tie those valuations back to the long term story behind the stock.

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

A Discounted Cash Flow model estimates what a business is worth by projecting the cash it can generate in the future and then discounting those cash flows back to today in $ terms. For Allison Transmission Holdings, the 2 Stage Free Cash Flow to Equity model starts with last twelve months free cash flow of about $654 million and applies analyst forecasts for the next several years, then extrapolates longer term growth beyond the explicit forecast horizon.

Analysts and model estimates see free cash flow rising toward roughly $1.56 billion by 2035, with a steady moderation in growth rates as the company matures. Simply Wall St discounts each year’s projected free cash flow back to today to arrive at a total equity value, and then divides by the number of shares to estimate a fair value per share.

On this basis, the intrinsic value is calculated at about $227 per share, implying the stock is trading at a roughly 58.1% discount to its modeled fair value at current prices near $95. On the DCF view, Allison Transmission Holdings appears materially undervalued rather than fully priced according to this model.

Approach 2: Allison Transmission Holdings Price vs Earnings

For profitable, established businesses like Allison Transmission Holdings, the price to earnings ratio is a practical way to gauge what investors are willing to pay today for each dollar of current profits. It naturally links valuation to earnings power, which tends to be more stable and intuitive for mature industrial companies than revenue or book value.

In general, faster growing and lower risk companies tend to trade on a higher, or more expensive, PE multiple, while slower growth or higher uncertainty tends to be associated with a lower one. Allison currently trades on a PE of about 11.3x. That is well below both the Machinery industry average of roughly 25.1x and the peer group average of around 20.6x, suggesting the market is pricing its earnings at a discount to many competitors.

Simply Wall St also uses a Fair Ratio framework, which estimates what PE multiple a company might trade on after factoring in its earnings growth outlook, profitability, risk profile, size, and industry. This can be more informative than a simple peer or industry comparison because it adjusts for Allison’s specific characteristics. Allison’s Fair PE Ratio is estimated at about 23.3x, notably higher than its current 11.3x, indicating that on this measure the shares may be trading below that estimated level.
