1 Cash-Producing Stock with Exciting Potential and 2 We Brush Off

SCI Cover Image

While strong cash flow is a key indicator of stability, it doesn’t always translate to superior returns. Some cash-heavy businesses struggle with inefficient spending, slowing demand, or weak competitive positioning.

Not all companies are created equal, and StockStory is here to surface the ones with real upside. Keeping that in mind, here is one cash-producing company that leverages its financial strength to beat its competitors and two best left off your watchlist.

Two Stocks to Sell:

Service International (SCI)

Trailing 12-Month Free Cash Flow Margin: 15.4%

Founded in 1962, Service International (NYSE: SCI) is a leading provider of death care products and services in North America.

Why Do We Think Twice About SCI?

  1. Performance surrounding its funeral services performed has lagged its peers
  2. Estimated sales growth of 2.6% for the next 12 months is soft and implies weaker demand
  3. Eroding returns on capital from an already low base indicate that management’s recent investments are destroying value

At $76.50 per share, Service International trades at 19.5x forward P/E. Dive into our free research report to see why there are better opportunities than SCI.

Rush Enterprises (RUSHA)

Trailing 12-Month Free Cash Flow Margin: 9.9%

Headquartered in Texas, Rush Enterprises (NASDAQ: RUSH.A) provides truck-related services and solutions, including sales, leasing, parts, and maintenance for commercial vehicles.

Why Do We Avoid RUSHA?

  1. Sales trends were unexciting over the last two years as its 2.2% annual growth was below the typical industrials company
  2. Sales are projected to tank by 1.5% over the next 12 months as demand evaporates
  3. Falling earnings per share over the last two years has some investors worried as stock prices ultimately follow EPS over the long term

Rush Enterprises’s stock price of $54 implies a valuation ratio of 8.6x forward EV-to-EBITDA. Read our free research report to see why you should think twice about including RUSHA in your portfolio.

One Stock to Watch:

Globalstar (GSAT)

Trailing 12-Month Free Cash Flow Margin: 101%

Known for powering the emergency SOS feature in newer Apple iPhones, Globalstar (NASDAQ: GSAT) operates a network of low-earth orbit satellites that provide voice and data communications services in remote areas where traditional cellular networks don't reach.

Why Are We Positive On GSAT?

  1. Annual revenue growth of 20.7% over the last two years was superb and indicates its market share increased during this cycle
  2. Incremental sales over the last two years have been highly profitable as its earnings per share increased by 33.7% annually, topping its revenue gains
  3. Strong free cash flow margin of 27.9% enables it to reinvest or return capital consistently, and its rising cash conversion increases its margin of safety

Globalstar is trading at $26.22 per share, or 31.9x forward EV-to-EBITDA. Is now the time to initiate a position? Find out in our full research report, it’s free.
