Valuation

TransDigm Group valuation models and calculator

What the price is pricing in

The share price implies about 21.9% a year of cash-flow growth for five years.That is faster than the 15.8% a year revenue growth TransDigm Group has delivered.

  • Priced in21.9%
  • Last 12 months16.6%
  • 3 years a year17.0%
  • 5 years a year15.8%

Our cash-flow model with every input fixed except growth over the next five years, solved for the growth at which the model value equals the share price ($1208.52, Nov 3, 2026). Cash-flow growth then fades to 2.5% a year; discount rate 8.5%. Delivered figures are revenue growth from SEC filings.

How we got here: a discounted-cash-flow model of TransDigm Group's free cash flow after stock-based pay with after-tax interest added back ($2B, FY2026 Q3 TTM), growing 14.9% and 14.9% in the next two years (forecasts, guidance and its record), then back to 16.8% by year five, and fading to 2.5%, discounted at 8.5%. Lower and higher growth cases span ~$430–~$1100 ; that spread sets a 35% margin before we rate Buy or Sell.

Produced by Fundamentalytics' automated valuation model on November 3, 2026, using delayed market prices. Rating meanings, methodology and conflicts: recommendations disclosure and research disclaimer. General research, not personal advice — it does not consider your circumstances. Prices can fall as well as rise.

Our value per share comes from a discounted-cash-flow model of TransDigm Group's free cash flow after stock-based pay ( $2B, FY2026 Q3 TTM, with after-tax interest added back): growth for five years as below (the first two years from forecasts, guidance and the company's record), fading to 2.5%, discounted at 8.5%, then cash added and debt and other claims subtracted. These are model values under stated assumptions, not price targets or recommendations.

Valuation models

We value TransDigm Group as an operating company, with every model that fits that kind of business. Cost of equity 9.6%: the 10-year Treasury yield (4.9%) plus a beta of 1.03 times a 4.5% equity risk premium.

Value per share by model
Model Value per share In the combined value?
Cash-flow model (DCF) Free cash flow to the firm (after stock pay, with after-tax interest added back), grown then faded to 2.5%, discounted at 8.5% as the firm rate, less debt and other claims. ~$730 ~$430–$1100 Primary model, counts double
Forward price-to-earnings vs peers Next year's consensus earnings per share times peers' typical (harmonic-mean) forward price-to-earnings. Uses analysts' consensus estimates (third-party data), not our forecasts. ~$1200 ~$940–$1600 Included
Residual income Book value plus the present value of returns above the cost of equity, fading over ten years. — Does not apply: book value or earnings not available
Justified price-to-book Book value times (return on equity - growth) / (cost of equity - growth): steady-state returns. — Does not apply: return on equity is not positive
Combined value Weighted average of the models that apply: the primary model (cash-flow model (dcf)) counts double. Models more than 5x or less than 0.2x the share price, or more than 3x away from the other models' median, are left out. ~$870 ~$730–$1200 2 models

Different models fail in different ways, so where several apply we average them rather than trust one. Peer-based models compare TransDigm Group with Aerospace & Defense in our coverage, using third-party market data. Model values are estimates under stated assumptions, updated as new filings arrive; not price targets or investment advice. How each model works.

Options strategies

All options ideas

How TransDigm Group’s listed options are priced, and three ways to use them that follow from our valuation. Quotes are delayed, read November 2, 2026. Check the live chain at your broker before trading.

Cash-secured put

Not offered: rated Sell.

We suggest selling a put only on well-rated companies, at a strike where the price you would pay if assigned (strike less premium) is at or below our fair value.

Covered call

Not offered: no liquid call at or above our price target — the model says the upside is worth more than any listed strike.

For holders: sell a call at a strike at or above our fair value, so the shares are only sold at a price the model calls full value.

Collar

Not offered: no liquid put and call pair for the same expiry.

For holders of a stock trading at or above our fair value: buy a put for a floor and sell a call to pay for it.

General research, not personal advice. Options can lose you more than you expect and are not suitable for everyone: put sellers can be made to buy shares that keep falling, call sellers give up gains above the strike, and results or news can move prices sharply. Chances shown are approximations from each option’s delta. Spreads, fees and early assignment are not modelled.
