3 Cash-Burning Stocks Walking a Fine Line

NMRK Cover Image

Companies that burn cash at a rapid pace can run into serious trouble if they fail to secure funding. Without a clear path to profitability, these businesses risk dilution, mounting debt, or even bankruptcy.

Just because a company is spending heavily doesn’t mean it’s on the right track, and StockStory is here to separate the winners from the losers. That said, here are three cash-burning companies that don’t make the cut and some better opportunities instead.

Newmark (NMRK)

Trailing 12-Month Free Cash Flow Margin: -5.3%

Founded in 1929, Newmark (NASDAQ: NMRK) provides commercial real estate services, including leasing advisory, global corporate services, investment sales and capital markets, property and facilities management, valuation and advisory, and consulting.

Why Should You Sell NMRK?

  1. 4.9% annual revenue growth over the last five years was slower than its consumer discretionary peers
  2. Negative free cash flow raises questions about the return timeline for its investments
  3. ROIC of 3.1% reflects management’s challenges in identifying attractive investment opportunities

Newmark’s stock price of $12.25 implies a valuation ratio of 8.8x forward P/E. If you’re considering NMRK for your portfolio, see our FREE research report to learn more.

Fluence Energy (FLNC)

Trailing 12-Month Free Cash Flow Margin: -12.5%

Pioneering the use of lithium-ion batteries for grid storage, Fluence (NASDAQ: FLNC) helps store renewable energy sources with battery systems.

Why Does FLNC Worry Us?

  1. Competitive supply chain dynamics and steep production costs are reflected in its low gross margin of 6.4%
  2. Investments to defend its competitive moat have ramped up over the last five years as its free cash flow margin decreased by 12 percentage points
  3. Short cash runway increases the probability of a capital raise that dilutes existing shareholders

Fluence Energy is trading at $7.95 per share, or 19.5x forward P/E. Check out our free in-depth research report to learn more about why FLNC doesn’t pass our bar.

Vertex Pharmaceuticals (VRTX)

Trailing 12-Month Free Cash Flow Margin: -11.3%

Founded in 1989 with a mission to create medicines that treat the underlying causes of disease rather than just symptoms, Vertex Pharmaceuticals (NASDAQ: VRTX) develops and markets transformative medicines for serious diseases, with a focus on cystic fibrosis, sickle cell disease, and pain management.

Why Are We Hesitant About VRTX?

  1. Performance over the past five years shows its incremental sales were much less profitable, as its earnings per share fell by 15.6% annually
  2. Capital intensity has ramped up over the last five years as its free cash flow margin decreased by 58.8 percentage points
  3. Diminishing returns on capital suggest its earlier profit pools are drying up

At $475.27 per share, Vertex Pharmaceuticals trades at 25.5x forward P/E. To fully understand why you should be careful with VRTX, check out our full research report (it’s free).
