The merger I modelled two years early

In the autumn of 2010, I led a small team of Cranfield Executive MBA classmates through an M&A assignment: choose a live UK target, build the acquisition case from public information only, and defend it. We chose soft drinks. Our proposal: Britvic plc acquires A.G. Barr.

Working entirely from annual reports, market data and trade press, we produced a full offer document. A cash offer of £15.06 per share, a 20 per cent premium, valuing A.G. Barr at 17.0 times its forecast FY11 EBIT of £34.49m, financed by a share issue and senior notes. The strategic logic was consolidation: Britvic and Barr together held roughly 20 per cent of a UK market whose leader controlled more than 60. The combination bought brand breadth across carbonates and stills, and a platform for European growth.

We went deep on the integration mechanics, because that is where acquisition cases live or die. Cumbernauld became the carbonates centre of excellence and Tredegar the home of stills and Rubicon, with two smaller sites closing. Cost of sales moved from 42.7 to 40.2 per cent over five years. We built £70.2m of combined year-one value across salesforce rationalisation, operations and the de-duplication of central functions and board costs, against £3.4m of one-off integration spend. We mapped succession seat by seat, kept Robin Barr on a two-year consultancy, and retained Roger White - A.G. Barr's chief executive - to head a transformed international division. And we flagged one risk above all others: competition approval.

The scenario was dated 1 October 2010. The paper scored well, and we moved on.

Putting it in front of Britvic

Sixteen months later I did something slightly unusual: I sent it to Britvic. On 20 February 2012 the document went to someone senior in the company, with a short covering note. On 6 March the office acknowledged it and passed it to the Group Financial Controller.

Let me be precise about what I am not claiming. Boards do not buy companies because an MBA team posts them a document, and I make no claim of causation whatsoever. What follows is simply the public record.

In September 2012, six and a half months after my email, Britvic and A.G. Barr confirmed they were in merger talks. On 14 November 2012 they announced an all-share merger valuing the combination at around £1.4bn - Britvic shareholders taking 63 per cent, Barr's 37 - to be called Barr Britvic Soft Drinks.

The mirrors

Set the 2010 case beside the 2012 announcement and the alignment is striking.

The strategic logic was identical: UK consolidation to build a credible challenger, brand breadth across the portfolio, a European growth platform. Roger White, whom our case had deliberately retained, became chief executive of the entire combined group. Gerald Corbett, who signed our fictional offer letter because he was Britvic's real chairman, was named non-executive chairman of the combined business. The synergy programme fell into the same three families we had modelled: route-to-market and salesforce, operations, procurement and supply chain, and central overhead.

The divergences - which teach more than the mirrors

Two things diverged, and both carry lessons I still use.

First, structure. We modelled a premium cash acquisition; the boards chose a nil-premium all-share merger. It is the same strategic question answered with a different risk appetite - nobody writes a cheque, nobody pays a premium, both sets of shareholders keep exposure to the upside and the integration risk.

Second, quantum. Our £70.2m of year-one combined value stood against the announced roughly £35m of recurring cost synergies plus about £5m of net revenue benefit. Here is the honest self-assessment: a student case is priced to argue; a board case is priced to defend. We weighted revenue synergies and totalled year-one value because we were making a case. Boards announce cost-weighted, recurring numbers because they will be held to them quarter after quarter. The £30m gap was not ignorance of the businesses. It was the distance between advocacy and accountability - and knowing which side of that line you are standing on is a core discipline of transaction finance.

The clock that killed a cleared deal

Then came the part no one modelled fully - though we had named the category.

In February 2013 the Office of Fair Trading referred the merger to the Competition Commission, and under the takeover timetable the offer terms lapsed. During the months of review, Britvic changed underneath the deal: a new chief executive, its own cost programme, improving trading, a rising share price. In mid-2013 the Competition Commission cleared the merger. A.G. Barr returned on close to the original terms; Britvic, by then a stronger standalone business, wanted better ones; A.G. Barr declined; and in July 2013 the talks ended. The deal the regulator approved never happened.

We had flagged competition approval as the principal risk in 2010. It materialised - but not as a prohibition. It materialised as time. Eight months of regulatory delay let one side's standalone value outgrow the agreed terms. That is the lesson I carry into every transaction conversation since: the regulator's clock can kill a deal the regulator clears. Deal value is not static while you wait; the timetable itself is a risk position.

What I would build differently today

The 2010 case took our small team weeks of evenings: digesting filings, building comparables, modelling synergies line by line, stress-testing the financing. Today, with the AI toolset I run daily inside a governed workflow - provenance on every input, cross-examination of outputs, validation against source - the mechanical layer of that work compresses from weeks to days. Filings digestion, comparable screens, scenario trees, sensitivity runs: all faster, and with a wider search space than a small team could cover manually.

What does not compress is the judgement layer. The premium you can defend. The synergy number you are prepared to own in front of shareholders. The walk-away discipline when the clock moves the value under your feet. If anything, cheap analysis makes that distinction sharper: when the modelling is no longer the bottleneck, judgement is. Knowing which half of the work you are in - that is the finance leadership job, and no tool changes it.

Why this story matters

The value of the exercise was never prediction, and I would not dress it up as foresight. The value is what it demonstrates: that disciplined work on public information alone put a small team I led on the same strategic ground two boards reached two years later - the same consolidation logic, the same leadership answer, the same named risk. That is what board-grade preparation looks like from outside the data room. The craft transfers to any transaction where the numbers must survive scrutiny: build the case like an advocate, price it like the accountable party, and never take your eye off the clock.

The regulator's clock can kill a deal the regulator clears.
