LSE:SPT Earnings and Revenue Growth March 14th 2021

Taking into account the latest results, the most recent consensus for Spirent Communications from seven analysts is for revenues of US$562.8m in 2021 which, if met, would be a reasonable 7.7% increase on its sales over the past 12 months. Per-share earnings are expected to rise 4.5% to US$0.14. Yet prior to the latest earnings, the analysts had been anticipated revenues of US$561.4m and earnings per share (EPS) of US$0.15 in 2021. So it looks like there's been a small decline in overall sentiment after the recent results - there's been no major change to revenue estimates, but the analysts did make a minor downgrade to their earnings per share forecasts.

It might be a surprise to learn that the consensus price target was broadly unchanged at UK£2.72, with the analysts clearly implying that the forecast decline in earnings is not expected to have much of an impact on valuation. It could also be instructive to look at the range of analyst estimates, to evaluate how different the outlier opinions are from the mean. Currently, the most bullish analyst values Spirent Communications at UK£3.30 per share, while the most bearish prices it at UK£1.75. As you can see, analysts are not all in agreement on the stock's future, but the range of estimates is still reasonably narrow, which could suggest that the outcome is not totally unpredictable.

One way to get more context on these forecasts is to look at how they compare to both past performance, and how other companies in the same industry are performing. It's clear from the latest estimates that Spirent Communications' rate of growth is expected to accelerate meaningfully, with the forecast 7.7% annualised revenue growth to the end of 2021 noticeably faster than its historical growth of 2.5% p.a. over the past five years. Compare this with other companies in the same industry, which are forecast to grow their revenue 5.8% annually. Factoring in the forecast acceleration in revenue, it's pretty clear that Spirent Communications is expected to grow much faster than its industry.

The Bottom Line

The biggest concern is that the analysts reduced their earnings per share estimates, suggesting business headwinds could lay ahead for Spirent Communications. Fortunately, they also reconfirmed their revenue numbers, suggesting sales are tracking in line with expectations - and our data suggests that revenues are expected to grow faster than the wider industry. There was no real change to the consensus price target, suggesting that the intrinsic value of the business has not undergone any major changes with the latest estimates.

Keeping that in mind, we still think that the longer term trajectory of the business is much more important for investors to consider. At Simply Wall St, we have a full range of analyst estimates for Spirent Communications going out to 2023, and you can see them free on our platform here..
