Company Overview
Tackling hazardous waste challenges since 1990, Perma-Fix (NASDAQ: PESI) provides environmental waste treatment services.
Revenue Growth
A company’s long-term sales performance can indicate its overall quality. Even a bad business can shine for one or two quarters, but a top-tier one grows for years. Perma-Fix’s demand was weak over the last five years as its sales fell at a 10.2% annual rate. This wasn’t a great result and is a sign of poor business quality.
Long-term growth is the most important, but within industrials, a half-decade historical view may miss new industry trends or demand cycles. Perma-Fix’s recent performance shows its demand remained suppressed as its revenue has declined by 17.1% annually over the last two years. 
This quarter, Perma-Fix’s revenue grew by 6.9% year on year to $15.72 million, missing Wall Street’s estimates.
Looking ahead, sell-side analysts expect revenue to grow 68% over the next 12 months, an improvement versus the last two years. This projection is eye-popping and implies its newer products and services will spur better top-line performance.

Operating Margin
Perma-Fix’s high expenses have contributed to an average operating margin of negative 11% over the last five years. Unprofitable industrials companies require extra attention because they could get caught swimming naked when the tide goes out. It’s hard to trust that the business can endure a full cycle.
Looking at the trend in its profitability, Perma-Fix’s operating margin decreased by 9.7 percentage points over the last five years. Perma-Fix’s performance was poor no matter how you look at it - it shows that costs were rising and it couldn’t pass them onto its customers.
In Q4, Perma-Fix generated a negative 20.6% operating margin. The company's consistent lack of profits raise a flag.
Cash Is King
If you’ve followed StockStory for a while, you know we emphasize free cash flow. Why, you ask? We believe that in the end, cash is king, and you can’t use accounting profits to pay the bills.
Perma-Fix’s demanding reinvestments have drained its resources over the last five years, putting it in a pinch and limiting its ability to return capital to investors. Its free cash flow margin averaged negative 10.3%, meaning it lit $10.25 of cash on fire for every $100 in revenue.
Taking a step back, we can see that Perma-Fix’s margin dropped by 14.5 percentage points during that time. Almost any movement in the wrong direction is undesirable because it is already burning cash. If the trend continues, it could signal it’s becoming a more capital-intensive business.
Key Takeaways from Perma-Fix’s Q4 Results
We struggled to find many positives in these results. Its revenue missed and its EBITDA fell short of Wall Street’s estimates. Overall, this was a weaker quarter. The stock traded down 5.7% to $11.35 immediately after reporting.
Perma-Fix may have had a tough quarter, but does that actually create an opportunity to invest right now? The latest quarter does matter, but not nearly as much as longer-term fundamentals and valuation, when deciding if the stock is a buy.
