So far, 2025’s been a pretty terrible year for Greggs‘ (LSE:GRG) shares. The FTSE 250 stock’s down 45% since the start of January.
There are however, three reasons for thinking this might be set to change in October. There are no guarantees, but investors might well want to take a closer look.
Reason 1: growth
The main reason Greggs shares have been falling is revenue growth. The firm reported a 7% sales increase in July, but this was largely due to opening new stores during the first half of the year.
Adjusting for this, revenues were up less than 3% and like-for-like sales have been consistently disappointing since the start of 2024. But things are starting to show signs of recovery.

Management’s been citing unusual weather conditions for recent weak demand. With this out of the way however, there’s a chance like-for-like growth could start to pick up.
In this situation, the market might start to take a more positive view of the stock than it currently is. And the current multiple the stock’s trading at might well amplify the effect of this.
Reason 2: valuation
As a result of the recent declines, Greggs’ shares currently trade at a price-to-earnings (P/E) ratio of less than 11. And to some extent, I think that makes a lot of sense.
Right now though, the stock’s trading at one of its lowest multiples in the last five years. So if things start to pick up with the underlying business, I expect this to expand.

The shares trading at a P/E ratio of 12 would cause the price to jump 15%, even before the effect of any growth. Furthermore, earnings have also been held back by one-off expansion costs.
At their current level, I think even a modest surprise could cause Greggs shares to trade at a significantly higher multiple. And that could mean a lot in terms of the share price.
Reason 3: imminent update
Dramatic share price moves often come in response to company reports. This is because updates from businesses give investors the best chance to review their expectations.
Given this, it’s probably significant that Greggs is set to issue its trading update for the third quarter of 2025 at the start of October. And I suspect investors will be watching carefully.
Cost inflation’s probably the biggest issue facing the company at the moment. It’s the single largest reason operating income fell during the first half of the year and looks set to continue.
For the stock to move higher, investors will want to see Greggs being able to offset this through higher like-for-like sales growth. And we’ll get an update on this very soon.
Long-term view
Sales growth across the takeaway and fast food sector in the UK has been weak. While Greggs has faltered, the industry as a whole has seen declines.
From a long-term perspective, this is a very positive sign for Greggs. It means the company’s relatively resilient, even when the sector as a whole is under pressure.
Given this, I think long-term investors might want to take a look. At the current multiple, it might not take much from the business to get the share price moving.
