Is It Time To Reassess TransDigm Group (TDG) After Its Recent Share Price Stagnation?
Share
Listen to the news
  • Investors may be wondering whether TransDigm Group, at around US$1,265 per share, still offers value or if most of the opportunity is already priced in.
  • The stock has recently shown mixed signals, with a 4.9% return over 7 days and 5.5% over 30 days, alongside a 6.8% decline year to date and a 1.1% return over the past 12 months.
  • Those recent moves sit against a much stronger backdrop over longer periods, with returns of 93.7% over 3 years and 155.8% over 5 years suggesting a very different experience for longer term holders. This kind of split between short term softness and strong multi year gains often prompts investors to reassess whether the current price still lines up with their expectations.
  • Right now TransDigm Group holds a value score of 2 out of 6, so the next step is to look at what different valuation approaches say about the stock and then consider an even more complete way to think about valuation that will come at the end of this article.

TransDigm Group scores just 2/6 on our valuation checks. See what other red flags we found in the full valuation breakdown.

Approach 1: TransDigm Group Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model takes estimates of the cash a company could generate in the future, then discounts those back to today to arrive at an estimate of what the business might be worth now.

For TransDigm Group, the model used is a 2 Stage Free Cash Flow to Equity approach. The latest twelve month free cash flow is about $1.9b. Analyst and extrapolated projections see free cash flow figures between roughly $2.3b and $5.1b over the next ten years, with Simply Wall St extending estimates beyond the initial analyst horizon.

When all these projected cash flows are discounted back and combined, the DCF model arrives at an estimated intrinsic value of about $1,270.51 per share. Compared with the recent share price of around $1,265, this suggests the stock is about 0.4% undervalued, which is effectively a very small gap.

In short, the DCF model points to TransDigm Group trading very close to its estimated cash flow based value right now.

Result: ABOUT RIGHT

TransDigm Group is fairly valued according to our Discounted Cash Flow (DCF), but this can change at a moment's notice. Track the value in your watchlist or portfolio and be alerted on when to act.

Approach 2: TransDigm Group Price vs Earnings

For a profitable company like TransDigm Group, the P/E ratio is a useful way to see how much you are paying for each dollar of current earnings. It ties the share price directly to the bottom line, which many investors use as a quick check on whether expectations baked into the price feel reasonable.

What counts as a “normal” P/E often reflects how the market views a company’s growth prospects and risk. Higher expected growth or lower perceived risk can support a higher P/E, while slower expected growth or higher risk usually aligns with a lower P/E.

TransDigm Group currently trades on a P/E of 39.54x. That sits close to the Aerospace & Defense industry average P/E of 39.27x and the peer average of 38.24x. Simply Wall St’s Fair Ratio for TransDigm Group is 34.45x. This Fair Ratio is a proprietary estimate of what the P/E might be given factors such as earnings growth, industry, profit margin, market cap and company specific risks. Because it blends these elements, it gives a more tailored view than a simple comparison with peers or the broad industry.

Comparing the Fair Ratio of 34.45x with the current P/E of 39.54x suggests the stock is trading above this tailored estimate.
