Company Overview
Founded in 1991, Hudson Technologies (NASDAQ: HDSN) specializes in refrigerant services and solutions, providing refrigerant sales, reclamation, and recycling.
Revenue Growth
A company’s long-term sales performance is one signal of its overall quality. Any business can put up a good quarter or two, but many enduring ones grow for years. Over the last five years, Hudson Technologies grew its sales at an impressive 10.8% compounded annual growth rate. Its growth beat the average industrials company and shows its offerings resonate with customers.

We at StockStory place the most emphasis on long-term growth, but within industrials, a half-decade historical view may miss cycles, industry trends, or a company capitalizing on catalysts such as a new contract win or a successful product line. Hudson Technologies’s recent performance marks a sharp pivot from its five-year trend as its revenue has shown annualized declines of 7.6% over the last two years. 
This quarter, Hudson Technologies reported robust year-on-year revenue growth of 28.2%, and its $44.41 million of revenue topped Wall Street estimates by 16.5%.
Looking ahead, sell-side analysts expect revenue to grow 2.4% over the next 12 months. While this projection implies its newer products and services will catalyze better top-line performance, it is still below the sector average.

Operating Margin
Hudson Technologies has been a well-oiled machine over the last five years. It demonstrated elite profitability for an industrials business, boasting an average operating margin of 23.3%. This result isn’t surprising as its high gross margin gives it a favorable starting point.
Analyzing the trend in its profitability, Hudson Technologies’s operating margin decreased by 14.4 percentage points over the last five years. This raises questions about the company’s expense base because its revenue growth should have given it leverage on its fixed costs, resulting in better economies of scale and profitability.

In Q4, Hudson Technologies generated an operating margin profit margin of negative 25.2%, down 16.7 percentage points year on year. Since Hudson Technologies’s operating margin decreased more than its gross margin, we can assume it was less efficient because expenses such as marketing, R&D, and administrative overhead increased.
Earnings Per Share
Revenue trends explain a company’s historical growth, but the long-term change in earnings per share (EPS) points to the profitability of that growth – for example, a company could inflate its sales through excessive spending on advertising and promotions.
Hudson Technologies’s full-year EPS flipped from negative to positive over the last five years. This is encouraging and shows it’s at a critical moment in its life.

Like with revenue, we analyze EPS over a more recent period because it can provide insight into an emerging theme or development for the business.
Sadly for Hudson Technologies, its EPS declined by more than its revenue over the last two years, dropping 43.1%. This tells us the company struggled to adjust to shrinking demand.
We can take a deeper look into Hudson Technologies’s earnings to better understand the drivers of its performance. Hudson Technologies’s operating margin has declined over the last two years. This was the most relevant factor (aside from the revenue impact) behind its lower earnings; interest expenses and taxes can also affect EPS but don’t tell us as much about a company’s fundamentals.
In Q4, Hudson Technologies reported EPS of negative $0.20, down from negative $0.06 in the same quarter last year. This print missed analysts’ estimates, but we care more about long-term EPS growth than short-term movements. Over the next 12 months, Wall Street expects Hudson Technologies’s full-year EPS of $0.36 to grow 30.6%.
