Gamma's £1bn Buyout: Why Its Stock Trades Above the Offer Price

Here's a strange sentence about a British takeover announced on Tuesday: the target's shares are trading for more than the buyer agreed to pay.

The target is Gamma Communications (LSE: GAMA), the buyer is Epiris, a London private-equity firm. Epiris will pay 1,120 pence in cash for each Gamma share — £11.20, call it $15 — valuing the shares at about £1.0 billion and the company, including debt, at roughly £1.08 billion ($1.46 billion). Gamma's board recommends the deal. Yet on Tuesday morning the shares changed hands around 1,147 pence, a couple of percent above the number Epiris printed.

That inversion is not how agreed cash bids usually look. Normally a recommended cash offer leaves a discount beneath the offer price, the market's way of pricing the chance the deal falls apart. When the stock sits above the offer, the market is saying someone will eventually pay more — Epiris will be pushed to bump, or a rival bidder will appear, or both. Gamma has spent five months inside a takeover auction, so the expectation is not crazy.

The other thing that is odd about this deal is how it appears in the news feed. A large share of Gamma's takeover coverage for months has been syndicated copies of dry regulatory paperwork, the latest titled "Man Group PLC: Form 8.3 — Gamma Communications plc." It is a disclosure filed by Man Group, one of the world's largest listed hedge-fund managers, about its position in the company being bought. Forms like this are the plumbing that makes a UK takeover legible, and this one contains the strangest fact in the whole transaction.

First, the part that makes Gamma a takeover target at all. Gamma is a wholesaler of business communications — cloud phone systems, unified communications, SIP trunking — sold mostly through a channel of more than 1,500 resellers and managed-service providers, in the UK and three other European markets, rather than direct. That is the exact profile buyout firms like: recurring revenue (about 89% of sales), sticky customers, strong cash conversion (around 93%), and a nearly clean balance sheet. Revenue in 2025 was £645.8 million, adjusted EBITDA £141.7 million, net debt about £1.6 million in April. Epiris's line is that private ownership lets Gamma reinvest in products and AI without quarterly-reporting pressure; the board's line is that 1,120p is more than the company could plausibly be worth on its own in the foreseeable future.

The price has a carefully chosen reference point. Epiris's 1,120p is a 53% premium to the 732p close on April 7 — the day Gamma confirmed, in the Takeover Code's careful language, that it was in preliminary discussions with a number of interested counterparties about a possible sale. The Code measures premiums against that "undisturbed" price, fixed before the auction and its rumors moved the stock. Then the rumor wave did what rumor waves do: the shares drifted up through the summer and closed at 1,140p the Friday before the announcement, already above the number Epiris put in the offer document. (A footnote for the reference-point crowd: Gamma's own buyback program, announced before the auction started, kept buying its shares at a bit under 981p on average as late as August 10. Two weeks later the board agreed those same shares were worth 1,120p.)

The auction itself is worth understanding because the Code is what turned it into an auction. In a UK offer period there is no such thing as open-ended "we might bid": each interested buyer gets a put-up-or-shut-up deadline to announce a firm offer or walk away, and a target board that wants competition asks the Takeover Panel for extensions. Over the spring the interested buyers included Epiris, the American firm Providence Equity, and a consortium of Oakley Capital with Giacom, a fellow British communications provider whose involvement raised uncomfortable questions about Gamma's wholesale role. Bidders merged and split — Providence, briefly part of a joint effort with Epiris, left in late June, and Oakley dropped out in early July — leaving Epiris alone with deadlines pushed from June 12 to July 8 to August 5 to September 2. It announced the firm offer on September 1, a day early.

The Form 8.3 is the part to read carefully. Under the Takeover Code, once a company is in an offer period, anyone with interests in its “relevant securities” totaling 1% or more must disclose where they stand, and then every purchase and sale after that. The subtle part is what counts: the Code treats derivatives over the shares — options, swaps, contracts for difference — as interests in relevant securities. Man Group's filing, for its position as of August 17, shows why that matters. Its total was 1,705,952 shares-equivalent, 1.91% of Gamma. But only 177,750 of those were actual shares (0.19%). The other 1,528,202, about nine-tenths of the position, were "cash-settled derivatives": contracts in which a bank pays the manager the return on Gamma's shares — including, in a takeover, the offer consideration — in exchange for a fee and the funding.

That is economic ownership without the shares. Man Group collects the upside of the takeover without holding the votes; behind those contracts, typically, a bank sits with the real shares as its hedge, and when a cash offer comes the whole chain settles at Epiris's price. Same upside, same deal risk, wearing a different costume — and the Code says you must name it anyway. For scale, this is nearly a rounding error for the filer: 1.91% of Gamma is about £19 million at the offer price, inside a manager that reported a record $253.6 billion of assets under management as of June 30. The form is a reminder that in a UK takeover, nobody relevant gets to stay anonymous — and that a big institutional "holder" of a small company often looks less like a shareholder and more like a contract with a bank.

For an investor trying to make sense of Gamma now, the offer mechanics are the easy part. This is a scheme of arrangement, meaning a vote: if 75% of voting shareholders (by value, plus a majority in number) approve it and a court sanctions it, every Gamma share converts into the right to be paid 1,120p in cash. There are no holdouts — the scheme sweeps up everyone, at the same number, and Epiris can switch to a plain takeover offer if the scheme route goes wrong. The harder part is time. Completion is expected in the first half of 2027, with regulatory clearances needed across a list of countries, including Germany's foreign-investment review and approvals in Austria, Australia, Spain, the Netherlands and the UK. Months of waiting means months of everything that can go wrong actually going wrong.

Which brings back the 1,147p. A buyer at that price is paying about 2% more than a bidder has already agreed to pay, and even that small gap is a bundle of bets: the deal closes, and somebody eventually pays more. Bumps happen — new bidders arrive, and final numbers are often what it takes to end an auction. Deals also break. If this one did, the fall has room: Gamma spent the summer near 980p, and the undisturbed price the Code used as its baseline is 732p.

The basic point sits right in the file name. "Form 8.3" is how a five-month, multi-buyer auction that ended in a £1 billion cash buyout showed up in your feed: not as drama, but as a hedge-fund manager confessing its swap position. That is the deal in its final form, though. Every position in it — shares, swaps, options, each suitor's cleared dossier — reduced to the same two figures: 1,120 pence, cash, per share. The only number that appears on no form is the market's 1,147p, still insisting there is more somewhere.
