1 Profitable Stock to Own for Decades and 2 Facing Challenges

TDG Cover Image

Not all profitable companies are built to last - some rely on outdated models or unsustainable advantages. Just because a business is in the green today doesn’t mean it will thrive tomorrow.

Not all profitable companies are created equal, and that’s why we built StockStory - to help you find the ones that truly shine bright. That said, here is one profitable company that generates reliable profits without sacrificing growth and two that may struggle to keep up.

Two Industrials Stocks to Sell:

Hillenbrand (HI)

Trailing 12-Month GAAP Operating Margin: 10.2%

Hillenbrand, Inc. (NYSE: HI) is an industrial company that designs, manufactures, and sells highly engineered processing equipment and solutions for various industries.

Why Do We Pass on HI?

  1. Sales trends were unexciting over the last two years as its 3.5% annual growth was below the typical industrials company
  2. Free cash flow margin shrank by 18.9 percentage points over the last five years, suggesting the company is consuming more capital to stay competitive
  3. Eroding returns on capital suggest its historical profit centers are aging

Hillenbrand’s stock price of $25.56 implies a valuation ratio of 10.7x forward P/E. Read our free research report to see why you should think twice about including HI in your portfolio.

Werner (WERN)

Trailing 12-Month GAAP Operating Margin: 3.1%

Conducting business in over a 100 countries, Werner (NASDAQ: WERN) offers full-truckload, less-than-truckload, and intermodal delivery services.

Why Should You Dump WERN?

  1. Products and services are facing significant end-market challenges during this cycle as sales have declined by 5.7% annually over the last two years
  2. Incremental sales over the last five years were much less profitable as its earnings per share fell by 37.2% annually while its revenue grew
  3. Waning returns on capital from an already weak starting point displays the inefficacy of management’s past and current investment decisions

Werner is trading at $28.74 per share, or 36.4x forward P/E. To fully understand why you should be careful with WERN, check out our full research report (it’s free).

One Industrials Stock to Buy:

TransDigm (TDG)

Trailing 12-Month GAAP Operating Margin: 46%

Supplying parts for nearly all aircraft currently in service, TransDigm (NYSE: TDG) develops and manufactures components and systems for military and commercial aviation.

Why Do We Love TDG?

  1. Existing business lines can expand without risky acquisitions as its organic revenue growth averaged 13% over the past two years
  2. Incremental sales significantly boosted profitability as its annual earnings per share growth of 24.9% over the last two years outstripped its revenue performance
  3. Strong free cash flow margin of 19.5% enables it to reinvest or return capital consistently, and its growing cash flow gives it even more resources to deploy

At $1,400 per share, TransDigm trades at 33.2x forward P/E. Is now the right time to buy? See for yourself in our full research report, it’s free.
