Allison Transmission Holdings has delivered a 225.8% total return over the past five years, yet its current share price still screens as cheap against an intrinsic value estimate from a Discounted Cash Flow (DCF) model and supporting market multiples. Recent defense contract wins add fresh cash flow expectations into the mix, raising the question of whether the market is still underpricing that future stream.

• A 225.8% return over five years points to a stock that has already rewarded long term holders, so any further upside now depends heavily on how accurately the current price reflects future cash flows.
• Large transmission orders tied to armored vehicle programs can support long duration revenue, while reliance on defense contracts may expose Allison Transmission Holdings to timing and budget risk from government customers.
• Across Simply Wall St's broader checks, Allison Transmission Holdings scores 5 out of 6 on valuation, which leans toward the stock still offering value rather than looking fully priced in.

The stock's next move may depend on whether the current US$119.64 share price already reflects that intrinsic value, or if the Discounted Cash Flow (DCF) estimate and other checks are still pointing to material undervaluation.

Is Allison Transmission Holdings a Bargain on Cash Flow?

The Discounted Cash Flow (DCF) model values Allison Transmission Holdings by projecting future free cash flows and discounting them back to today. On this measure, the company generated about $637.6 million in free cash flow over the latest twelve months, with the model using a growing cash flow profile that extends into the early 2030s.

On these assumptions, the DCF points to an estimated intrinsic value of about $235 per share, compared with the recent $119.64 share price. This implies the stock screens as roughly 49.2% undervalued. The recent $250 million CV90 MkIV transmission contract helps support those future cash flow expectations, yet the current price still sits well below the model’s estimate.

Overall, the Discounted Cash Flow workup suggests Allison Transmission Holdings stock currently looks undervalued relative to its projected cash generation.

Our Discounted Cash Flow (DCF) analysis suggests Allison Transmission Holdings is undervalued by 49.2%. Track this in your watchlist or portfolio, or discover 38 more high quality undervalued stocks.

Is Allison Transmission Holdings Still Cheap on Earnings?

The P/E ratio is a useful way to think about what you are paying for each dollar of earnings at Allison Transmission Holdings. At about 18.3x earnings, Allison Transmission trades at a discount to the broader Machinery industry average P/E of 27.9x and the peer group average of 34.2x.

A tailored fair P/E ratio for Allison Transmission, which reflects its sector, margins, size and risk profile, sits higher at about 28.7x. That is above the current 18.3x level, indicating the market is assigning a lower earnings multiple than this framework suggests for the stock. Combined with the discounted reading against both industry and peer averages, the earnings multiple suggests that investors are pricing Allison Transmission cautiously relative to comparable companies.

On this P/E comparison, Allison Transmission stock appears undervalued relative to both its custom fair multiple and sector benchmarks.

The Bottom Line

For Allison Transmission Holdings, both the Discounted Cash Flow (DCF) intrinsic value estimate and the earnings multiple work point in the same direction, with the stock screening as undervalued rather than fully priced. The key question from here is whether the cash flows implied by recent contracts and existing programs actually materialise in line with expectations, and whether the P/E gap to peers closes or proves justified. For investors, the crux of the bull versus bear debate is whether that apparent discount is compensation for real long term risks around product mix and defense exposure, or a mispricing that could correct as confidence in those cash flows firms up.
