Revenue Growth

A company’s long-term sales performance is one signal of its overall quality. Any business can have short-term success, but a top-tier one grows for years. Luckily, Plug Power’s sales grew at an impressive 10.9% compounded annual growth rate over the last five years. 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. Plug Power’s recent performance shows its demand has slowed significantly as its annualized revenue growth of 4.3% over the last two years was well below its five-year trend.

This quarter, Plug Power reported modest year-on-year revenue growth of 2.5% but beat Wall Street’s estimates by 5.6%.

Looking ahead, sell-side analysts expect revenue to grow 18.4% over the next 12 months, an improvement versus the last two years. This projection is eye-popping and suggests its newer products and services will fuel better top-line performance.

Operating Margin

Operating margin is a key measure of profitability. Think of it as net income - the bottom line - excluding the impact of taxes and interest on debt, which are less connected to business fundamentals.

Plug Power’s high expenses have contributed to an average operating margin of negative 167% 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, Plug Power’s operating margin decreased by 74.9 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. Plug Power’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.

Plug Power’s operating margin was negative 36% this quarter.

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.

Although Plug Power’s full-year earnings are still negative, it reduced its losses and improved its EPS by 4.9% annually over the last five years. The next few quarters will be critical for assessing its long-term profitability.

Like with revenue, we analyze EPS over a shorter period to see if we are missing a change in the business.

For Plug Power, its two-year annual EPS growth of 27.2% was higher than its five-year trend. Its improving earnings are an encouraging data point, but a caveat is that its EPS is still in the red.

In Q2, Plug Power reported EPS of negative $0.14, up from negative $0.20 in the same quarter last year. Despite growing year on year, this print missed analysts’ estimates. Over the next 12 months, Wall Street expects Plug Power to improve its earnings losses. Analysts forecast its full-year EPS will improve from negative $1.26 to negative $0.21.
