Harworth Rejects Sweetened £600m Peel Takeover Bid: Why the Valuation Gap Persists

Harworth Group's board unanimously rejected Peel Bidco's revised cash offer on 18 September 2026, telling shareholders who haven't accepted not to, and urging anyone who already has to withdraw their acceptance as soon as possible. The offer, at 177.5p per share, values the UK regeneration and property group at roughly £600m — up from an initial 172.5p approach, but still, in the board's assessment, well short of what the business is actually worth.

What makes this rejection different from an ordinary takeover skirmish is that Peel no longer has the option to simply walk away if Harworth keeps saying no. The offer became mandatory the day before the rejection, on 17 September, when Peel Bidco's stake crossed 30% of Harworth's voting share capital — triggering Rule 9 of the UK Takeover Code.

Rule 9 exists specifically to protect minority shareholders once a single holder, or a group acting together, accumulates enough voting power to exert effective control without having bought out everyone else. Once that 30% line is crossed, the Code converts what had been a voluntary approach into a mandatory cash offer to all remaining shareholders, priced at no less than the highest price the bidder paid for any shares in the twelve months before the threshold was crossed. Peel doesn't have the discretion to lower the price, add conditions beyond a simple majority acceptance, or withdraw the offer once it's live — the obligation is automatic and largely non-negotiable once the threshold is crossed.

The mechanics of how Peel actually crossed that line are almost mundane against the scale of what they triggered: Investegate's record of the announcement shows Peel Bidco acquired a further 137,669 Harworth shares — just 0.04% of the voting capital — through ordinary market purchases, taking its combined stake, together with parties acting in concert with it, from 29.96% to exactly 30.00%. The Code doesn't name the specific concert party members in the announcement itself, but the acting-in-concert language means shares held by parties coordinating with Peel count toward the same 30% threshold, not just Peel's own direct holding.

For shareholders, the board's advice is unambiguous rather than hedged: take no action if you haven't accepted, and withdraw if you have. That's a stronger instruction than a board typically gives in a contested bid, and it reflects the board's view that the mandatory nature of the offer doesn't make the price any less inadequate — Rule 9 forces Peel to make a cash offer to everyone, but it says nothing about whether that offer represents fair value.

Harworth's central argument on value rests on a single comparison: its own EPRA Net Disposal Value, a standard industry measure of net asset value adjusted for how a property company would realistically dispose of its portfolio, stood at 214.8p per share as of 30 June 2026. Peel's 177.5p offer sits 17.4% below that figure — a discount the board argues investors shouldn't need to accept from a bidder that's already crossed the threshold requiring it to buy them out regardless.

Harworth went further than simply citing its NDV, putting its own explicit counter-valuation on the table: 297.4p per share, implying a value of roughly £973m — 72% above Peel's bid. That figure rests on three things the board says the market isn't yet pricing in: continued progress on a hyperscale data centre site within Harworth's land portfolio, the sale of a 40-acre site in St Helens at book value, and a cost-cutting programme targeting at least £7.4m in annualised savings by the end of 2028, of which £1.3m has already been realised. Peel has pushed back hard on that number, calling Harworth's growth projections "unsubstantiated and unconvincing" and arguing the underlying business's financial performance is actually deteriorating rather than improving.

There's a structural detail in how Peel is buying Harworth that matters more than it might first appear: because this is a takeover of Harworth's corporate shares rather than a direct purchase of the underlying land and buildings, Peel avoids the Stamp Duty Land Tax it would otherwise owe on a direct property acquisition — an estimated £30.7m saving, equivalent to roughly 9.5p per share. That's value Peel captures purely through deal structure, independent of anything Harworth's underlying assets do next, and it's part of why the board frames the headline price as understating what Peel is actually getting.

Harworth sits inside a broader pattern that's been reshaping UK-listed real estate for much of the past two years: persistent share-price discounts to net asset value have made property companies attractive targets for buyers willing to pay a premium to the market price while still acquiring assets below what the company itself says they're worth. A bidder crossing the mandatory-offer threshold doesn't need the board's blessing to force a shareholder vote on exiting at a fixed price — it only needs enough shareholders willing to sell into that price, which is precisely why Harworth's board is now making its counter-valuation case as publicly and specifically as it has.

What happens next depends on how the remaining roughly 70% of Harworth's shareholder base responds, not on any further move available to the board itself. Peel has said it intends to seek Harworth's delisting from the London Stock Exchange if acceptances reach 75%, with compulsory acquisition powers available at 90% — thresholds that would let it acquire the remainder of the company regardless of individual shareholders' wishes. Until either of those levels is reached, the board's rejection stands, and the practical question for Harworth investors is whether they trust the company's own 297.4p valuation of its data centre and logistics pipeline enough to hold out for it.
