Shareholders in Alector, Inc. (NASDAQ:ALEC) may be thrilled to learn that the analysts have just delivered a major upgrade to their near-term forecasts. The consensus estimated revenue numbers rose, with their view now clearly much more bullish on the company's business prospects. Alector has also found favour with investors, with the stock up a magnificent 36% to US$2.09 over the past week. It will be interesting to see if today's upgrade is enough to propel the stock even higher.

Following the latest upgrade, the current consensus, from the six analysts covering Alector, is for revenues of US$11m in 2026, which would reflect a sizeable 21% reduction in Alector's sales over the past 12 months. Losses are presumed to reduce, shrinking 19% per share from last year to US$0.86. However, before this estimates update, the consensus had been expecting revenues of US$6.9m and US$0.86 per share in losses. So there's definitely been a change in sentiment in this update, with the analysts upgrading this year's revenue estimates, while at the same time holding losses per share steady.

These estimates are interesting, but it can be useful to paint some more broad strokes when seeing how forecasts compare, both to the Alector's past performance and to peers in the same industry. One more thing stood out to us about these estimates, and it's the idea that Alector's decline is expected to accelerate, with revenues forecast to fall at an annualised rate of 37% to the end of 2026. This tops off a historical decline of 30% a year over the past five years. By contrast, our data suggests that other companies (with analyst coverage) in a similar industry are forecast to see their revenue grow 23% per year. So it's pretty clear that, while it does have declining revenues, the analysts also expect Alector to suffer worse than the wider industry.

The Bottom Line

The most important thing here is that analysts reduced their loss per share estimates for this year, reflecting increased optimism around Alector's prospects. Pleasantly, analysts also upgraded their revenue estimates, and their forecasts suggest the business is expected to grow slower than the wider market. Seeing the dramatic upgrade to this year's forecasts, it might be time to take another look at Alector.
