System1 Group rejects Brave Bison bid as market values SYS1 above the offer

System1 Group PLC (AIM: SYS1) has escalated its defence against Brave Bison Group plc by formally recommending that shareholders reject an unsolicited takeover offer whose implied value has fallen below System1 Group’s prevailing market price. Based on Brave Bison’s September 9 closing price of 87p, the cash-and-shares proposal was worth approximately 312.5p for each System1 Group share, an 8.1% discount to System1 Group’s 340p closing price that day. The gap is particularly significant because takeover bids ordinarily need to compensate shareholders for surrendering control rather than ask them to accept less than the stock market is already offering.

The resistance is not limited to the board. System1 Group said its directors, representing 8.13% of the issued share capital, and other shareholders representing another 13.48% had provided written confirmations that they had no current intention of accepting the Brave Bison offer. Together, that amounts to approximately 21.61% of System1 Group’s issued ordinary shares.

Why is System1 Group trading above Brave Bison’s takeover offer?

Brave Bison’s cash-and-shares offer consists of 135p in cash and 2.04 new Brave Bison shares for each System1 Group share, while shareholders can instead elect for an alternative all-share consideration of 3.36 Brave Bison shares. Because a substantial portion of both structures depends on the value of Brave Bison’s own equity, the economic value of the proposal moves with Brave Bison’s share price rather than remaining fixed.

That has increasingly become a problem for the bidder. The cash-and-shares proposal implied approximately 321.7p per System1 Group share using Brave Bison’s July 29 price, fell to approximately 307.4p using its August 26 price and recovered to 312.5p using the September 9 close. System1 Group, meanwhile, closed at 340p on September 9 and remained around 336–338p immediately after publishing its response, meaning the market continued to attach materially more value to the standalone shares than to the bid consideration.

Using System1 Group’s approximately 12.69 million shares in issue excluding treasury stock, the difference between 340p and the 312.5p implied offer value equates to roughly £3.5 million of equity value. That calculation is only a snapshot because Brave Bison’s share price can change, but it illustrates why the board’s argument is unusually tangible: investors are not merely debating whether the premium is generous enough; the quoted consideration was below the prevailing market value.

Is improving FY27 trading strengthening System1 Group’s negotiating position?

System1 Group has also provided fresh operating evidence to support its rejection. Unaudited revenue for the first five months of FY27, covering April through August 2026, reached £15.9 million compared with £14.3 million during the corresponding prior-year period, representing growth of approximately 11%. The company said it remained comfortable with its FY27 profit forecast and noted that the United States had become its largest revenue market for the first time.

That development matters because the takeover dispute is partly about which share price should form the appropriate reference point. Brave Bison has highlighted premiums against much lower System1 Group prices earlier in 2026, including the 198p closing price on February 27. System1 Group argues that subsequent trading improvements independently contributed to its rerating, pointing to positive company updates in March, April and July before the latest takeover developments.

The company’s shares were at 305p on July 10, immediately before the current offer period began, compared with around 336–340p recently. That makes the debate more complicated than simply comparing the takeover terms with an undisturbed February price, because operational expectations had already started changing.

Could Brave Bison need to improve the economics if it wants control of System1 Group?

The current numbers suggest the bidder faces a straightforward problem. If System1 Group shares continue trading comfortably above the economic value of the offer, accepting the proposal becomes difficult to justify purely on price unless shareholders believe Brave Bison’s shares will appreciate substantially or the standalone System1 Group valuation is unsustainable.

There is another unusual feature. System1 Group reported £12.4 million of cash at March 31, while the company calculates that the cash element of Brave Bison’s proposal for shares it does not already own would require approximately £12.4 million. System1 Group has consequently argued that its own balance-sheet cash is broadly comparable with the debt funding Brave Bison would use to finance the cash component of the acquisition.

That does not invalidate the takeover structure, but it gives existing investors another valuation reference point. System1 Group is not presenting itself as a distressed target requiring an acquirer’s financial support; it is presenting a cash-backed growth business whose US revenue momentum is improving.

What should SYS1 investors watch as the takeover battle develops?

The most consequential variables are now Brave Bison’s share price, any improvement in the offer terms and the level of shareholder support each side can secure. Because part of the consideration is equity, a fall in Brave Bison shares automatically weakens the economic proposition unless the exchange ratio or cash component changes.

System1 Group’s trading performance will matter just as much. Continued double-digit revenue growth and delivery against FY27 profit expectations would make the board’s standalone argument easier to defend, while operational disappointment could narrow the valuation gap and strengthen Brave Bison’s hand.

For now, the stock market is sending a relatively clear signal. System1 Group shareholders have recently been able to value their shares above the bid rather than below it, while holders representing more than one-fifth of the company have indicated that they currently do not intend to accept. That leaves Brave Bison with a takeover proposal whose strategic logic may still be debated, but whose immediate pricing problem is much harder to ignore.
