Bloom Energy Corporation (NYSE:BE) shares have had a really impressive month, gaining 33% after a shaky period beforehand. This latest share price bounce rounds out a remarkable 451% gain over the last twelve months.

Following the firm bounce in price, when almost half of the companies in the United States' Electrical industry have price-to-sales ratios (or "P/S") below 2.3x, you may consider Bloom Energy as a stock not worth researching with its 17.8x P/S ratio. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's so lofty.

What Does Bloom Energy's P/S Mean For Shareholders?

Bloom Energy certainly has been doing a good job lately as it's been growing revenue more than most other companies. The P/S is probably high because investors think this strong revenue performance will continue. If not, then existing shareholders might be a little nervous about the viability of the share price.

Do Revenue Forecasts Match The High P/S Ratio?

The only time you'd be truly comfortable seeing a P/S as steep as Bloom Energy's is when the company's growth is on track to outshine the industry decidedly.

Taking a look back first, we see that the company grew revenue by an impressive 45% last year. The strong recent performance means it was also able to grow revenue by 69% in total over the last three years. So we can start by confirming that the company has done a great job of growing revenue over that time.

Shifting to the future, estimates from the analysts covering the company suggest revenue should grow by 48% per annum over the next three years. That's shaping up to be materially higher than the 16% per year growth forecast for the broader industry.

With this in mind, it's not hard to understand why Bloom Energy's P/S is high relative to its industry peers. It seems most investors are expecting this strong future growth and are willing to pay more for the stock.

The Bottom Line On Bloom Energy's P/S

Shares in Bloom Energy have seen a strong upwards swing lately, which has really helped boost its P/S figure. Using the price-to-sales ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

Right now shareholders are comfortable with the P/S as they are quite confident future revenues aren't under threat.
