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

A Discounted Cash Flow model projects a company’s future cash that could be available to shareholders, then discounts those cash flows back to today to estimate what the business might be worth now.

For Allison Transmission Holdings, the latest twelve month Free Cash Flow is about $692.2 million. Using a 2 Stage Free Cash Flow to Equity model, analysts and extrapolations assume FCF in the range of $649.7 million for 2026 and $943.5 million for 2027, with projections extending out to $1,220.0 million by 2030. Simply Wall St only uses analyst estimates where available, then extrapolates further years to build a full 10 year cash flow path in dollars.

After discounting these projected cash flows, the model arrives at an estimated intrinsic value of about $230.70 per share. Compared to the recent share price of $117.46, this implies the stock is 49.1% undervalued based on this DCF approach.

Approach 2: Allison Transmission Holdings Price vs Earnings

For profitable companies, the P/E ratio is a useful shorthand because it tells you how much you are paying for each dollar of current earnings. What counts as a “normal” P/E depends on how quickly earnings are expected to grow and how risky those earnings are, with higher growth or lower perceived risk often associated with a higher multiple.

Allison Transmission Holdings currently trades on a P/E of 15.7x. This sits below both the Machinery industry average P/E of 26.2x and the peer average of 23.9x. This suggests the market is applying a lower earnings multiple than it does to many similar companies.

Simply Wall St’s “Fair Ratio” for Allison Transmission Holdings is 25.0x. This is a proprietary estimate of what the P/E might be given the company’s earnings profile, industry, profit margins, market cap and specific risks. Because it factors in these company-level drivers, the Fair Ratio can be more tailored than a simple comparison with peers or a broad industry average.

Comparing the current P/E of 15.7x with the Fair Ratio of 25.0x indicates the shares trade at a discount on this earnings multiple approach.

Result: UNDERVALUED

🐂 Allison Transmission Holdings Bull Case

Fair value in this bullish narrative: US$174.73 per share.

Implied discount to this fair value at US$117.46: around 33%.

Revenue growth assumption: 31.23% a year.

• Focuses on expansion in electrified defense systems, fuel-agnostic and hybrid solutions, and the Dana Off Highway acquisition as key earnings drivers.
• Builds in faster revenue growth with some margin compression, plus ongoing share buybacks and a 15.9x P/E on forecast 2029 earnings.
• Flags risks from faster electrification, regulation, integration of Dana and tougher competition that could challenge these optimistic assumptions.

🐻 Allison Transmission Holdings Bear Case

Fair value in this bearish narrative: US$92.00 per share.

Implied premium to this fair value at US$117.46: around 28%.

Revenue growth assumption: 26.19% a year.

• Emphasises exposure to internal combustion transmissions, regulatory pressure and technology shifts that could weigh on long term demand.
• Highlights customer concentration and a debt-funded acquisition as adding financial and execution risk if end markets soften or synergies take longer.
• Allows for support from electrified products, defense contracts, pricing and aftermarket, but still concludes that upside could be restrained if expectations are already embedded in the price.

These two frameworks sit on opposite sides of the debate and give you clear starting points to test your own assumptions against the current share price.
