Greggs (LSE: GRG) shares surged around 10% over the course of a week following a profit upgrade that caught the attention of investors across the market.
The rally was triggered by a trading update covering the 13 weeks to 26 September, which delivered some concrete and encouraging growth figures for shareholders to digest.
Total sales rose 7.7% compared with the same quarter last year, while sales at company-managed shops open in both periods climbed a more modest 3.4%.
That like-for-like figure carries real weight because it strips out the flattering effect of new store openings, suggesting existing outlets are genuinely selling more volume.
Management pointed to new products and more settled weather as factors that helped trading during the period, adding some texture to the headline numbers.
The company now expects a “modestly improved” outcome for 2026, a phrase that offers cautious optimism without making any bold promises about the pace of recovery.
Greggs still plans to open around 100 to 110 net new shops this year, and those new locations will need to justify their existence through consistent, profitable trading over time.
However, the word “modestly” in that profit upgrade is doing considerable heavy lifting, and it does not exactly inspire confidence about what conditions might look like heading into 2027.
New distribution centres in Derby and Kettering are expected to generate significant costs before delivering any meaningful profit contribution, adding pressure to near-term financials.
Management has also flagged greater inflationary pressure expected in the coming year, which could squeeze margins at a time when consumer spending remains uncertain across the broader economy.
A proposed manufacturing overhaul adds further complexity to the investment case, with four sites potentially facing closure and around 740 roles at risk of redundancy over two and a half years.
Greggs estimates the restructuring will carry around £60m in cash costs, with anticipated annual savings of approximately £20m expected to be realised across 2028 and 2029.
Those savings remain a forecast rather than a guaranteed outcome, and investors should weigh that distinction carefully when assessing the longer-term value of the business.
Shareholder Mark Hartley, who owns shares in Greggs, acknowledged the tension that comes with watching a held stock surge, describing the choice between buying more and doing nothing as genuinely uncomfortable.
His conclusion was measured: the improvement in sales provides some optimism, but the jump in share price does not immediately persuade him to add more exposure, nor does it warrant taking profits at this stage.
For now, the shares represent a Hold, with future monitoring focused on existing shop growth and whether new infrastructure can eventually deliver returns that outweigh their considerable upfront costs.
