The owners of Hovis and Kingsmill, two of Britain’s leading bread producers, are in talks about a historic merger amid a decades-long decline in the sale of supermarket loaves.

Sky News has learnt that Associated British Foods (ABF), the London-listed company which owns Kingsmill’s immediate parent, Allied Bakeries, and Hovis, which is owned by investment firm Endless, have been involved in prolonged discussions about a combination of the two businesses.

City sources said this weekend that the talks were ongoing, but that there was no certainty that a deal would be finalised.

Bankers are said to be working with both sides on the talks about a transaction.

A deal could be structured as an acquisition of Hovis by ABF, according to analysts, although details about the mechanics of a merger or the valuations attached to the two businesses were unclear this weekend.

ABF is also said to be exploring other options for the future of Allied Bakeries which do not include a deal with Hovis.

If completed, a merger would unite two of Britain’s best-known ambient food brands, with Allied Bakeries having been founded in 1935 by Willard Garfield Weston, part of the family which continues to control ABF.

Hovis traces its history back even further, having been created in 1890 when Herbert Grime scooped a £25 prize for coming up with the name Hovis, which was derived from the Latin ‘Hominis Vis’ – meaning strength of man.

Persistent inflation, competition from speciality bread producers and shifting consumer habits towards lower-carb diets have combined to impair the bread industry’s financial health in recent decades.

The impact of the war in Ukraine on wheat and flour prices has been among the factors increasing inflationary pressures on bread producers, according to the most recent set of accounts for Hovis filed at Companies House last year.

The overall UK bakery market is said to be worth about £5bn in annual sales, with the equivalent of 11m loaves being sold each day.

The principal obstacle facing a merger of Allied Bakeries, which also owns the Sunblest and Allinson’s bread brands, and Hovis would reside in its consequences for competition in the UK market.

Warburtons, the family-owned business which is the largest bakery group in Britain, is estimated to have a 34% share of the branded wrapped sliced bread sector in the UK, with Hovis on 24% and Allied on 17%, according to industry insiders.

A merger of Hovis and Kingsmill would give the combined group a larger share of that segment of the market, although one source said Warburtons’ overall turnover would remain larger because of the breadth of its product range.

Nevertheless, reducing the number of major supermarket bread suppliers from three to two would be a test of the Competition and Markets Authority’s approach to such industry-reshaping mergers at a time when the watchdog is under intense government scrutiny.

In January, the government removed the CMA chairman, Marcus Bokkerink, as part of a push to reorient Britain’s economic regulators around growth-focused objectives.

An industry insider suggested that a joint venture involving the distribution networks of Hovis and Kingsmill was a possible, although less likely, alternative to a full-blown merger of the companies.

They added that a combined group could benefit from up to £50m of cost savings from such a tie-up.

In its interim results announcement this week, ABF said the performance of Allied Bakeries had continued to struggle.

“Allied Bakeries continues to face a very challenging market,” it said.

“We are evaluating strategic options for Allied Bakeries against this backdrop and we expect to provide an update in [the second half of] 2025.”

In a separate presentation to analysts, ABF described the losses at Allied as unsustainable.

The company does not disclose details of Allied Bakeries’ financial performance.

Allied also owns Speedibake, an own-label bread manufacturer.

Hovis has been owned by Endless, a prominent investor in British businesses, since 2020, having previously been owned by Mr Kipling-maker Premier Foods and the Gores family.

At the time of the most recent takeover, High Wycombe-based Hovis employed about 2,700 people and operated eight bakery sites and its own flour mill.

Hovis’s current chief executive, Jon Jenkins, is a former boss of Allied Milling and Baking.

This weekend, ABF and Endless both declined to comment.
