Mercury NZ Limited's (NZSE:MCY) Share Price Could Signal Some Risk

Simply Wall St

When you see that almost half of the companies in the Electric Utilities industry in New Zealand have price-to-sales ratios (or "P/S") below 1.2x, Mercury NZ Limited (NZSE:MCY) looks to be giving off some sell signals with its 2.5x 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 as high as it is.

What Does Mercury NZ's P/S Mean For Shareholders?

Recent times haven't been great for Mercury NZ as its revenue has been rising slower than most other companies. It might be that many expect the uninspiring revenue performance to recover significantly, which has kept the P/S ratio from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

What Are Revenue Growth Metrics Telling Us About The High P/S?

The only time you'd be truly comfortable seeing a P/S as high as Mercury NZ's is when the company's growth is on track to outshine the industry.

Taking a look back first, we see that there was hardly any revenue growth to speak of for the company over the past year. Although pleasingly revenue has lifted 60% in aggregate from three years ago, notwithstanding the last 12 months. So while the company has done a solid job in the past, it's somewhat concerning to see revenue growth decline as much as it has.

Turning to the outlook, the next three years should generate growth of 0.8% each year as estimated by the five analysts watching the company. That's shaping up to be materially lower than the 5.2% per annum growth forecast for the broader industry.

With this information, we find it concerning that Mercury NZ is trading at a P/S higher than the industry. Apparently many investors in the company are way more bullish than analysts indicate and aren't willing to let go of their stock at any price. Only the boldest would assume these prices are sustainable as this level of revenue growth is likely to weigh heavily on the share price eventually.

What We Can Learn From Mercury NZ's P/S?

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.

Despite analysts forecasting some poorer-than-industry revenue growth figures for Mercury NZ, this doesn't appear to be impacting the P/S in the slightest. When we see a weak revenue outlook, we suspect the share price faces a much greater risk of declining, bringing back down the P/S figures. Unless these conditions improve markedly, it's very challenging to accept these prices as being reasonable.
