Diageo — The Marketing Investment Discipline Model

Module: F9 — Marketing Finance Type: Marketing Investment Discipline Model Cross-references: F9-05 (budgeting and SOV), F9-06 (the business case for marketing investment), F9-07 (brand as a balance sheet asset), F9-08 (the evidence-based Marketing Finance Director, capstone)

The Situation

If the AB InBev case in this module is the cautionary tale of what happens when a publicly listed consumer-goods company allows financial discipline to consume its brand investment, the Diageo case is the positive counter-example. The two companies operate in the same broad sector (alcoholic beverages), are subject to the same shareholder-return pressures, are accountable to the same kind of equity analysts, and report under similar disclosure regimes. The difference is institutional. Diageo has, over more than two decades, built and maintained a marketing-finance discipline that protects brand investment from the annual cost-cutting reflex without abandoning the financial rigour that public markets demand. This case examines how.

Diageo is, by revenue, the world's largest spirits company. The group was formed in 1997 by the merger of Guinness and Grand Metropolitan, and its current portfolio reads like an inventory of category-defining brands: Johnnie Walker (the world's largest-selling Scotch whisky), Smirnoff, Captain Morgan, Tanqueray, Baileys, Don Julio, Casamigos, Crown Royal, Bulleit, and Guinness. As of fiscal 2023 (year ending June), Diageo reported net sales of approximately £17.1bn, operating profit of approximately £4.6bn, and a global presence in roughly 180 countries. The company is a constituent of the FTSE 100 and one of the most-followed consumer staples names in European equities.

The CEO whose tenure most clearly defines the marketing-investment discipline this case examines is Ivan Menezes. Menezes joined Diageo in 1997, immediately after the merger, having previously worked at Booz Allen, Whirlpool, and Nestlé. He held a sequence of roles including President of North America before being appointed CEO in July 2013, succeeding Paul Walsh. He held the role for almost exactly a decade until his death in June 2023, after which Debra Crew became CEO.

What is unusual about Menezes — and the reason he matters to this case — is the trajectory by which he reached the CEO role. He had been, in effect, Diageo's chief marketing operator for years before becoming CEO. His operational career inside the company was anchored in commercial and brand leadership rather than in finance or supply chain. He spoke marketing fluently. But he also spoke finance fluently, in a way that most CMOs do not, because his career path required him to defend marketing investment to skeptical capital markets year after year. By the time he became CEO, he was perhaps uniquely positioned among large-cap CEOs to argue for marketing investment in the language of shareholder value, because he had been doing exactly that as President of North America for the better part of a decade.

The CMO who became Menezes's most important institutional partner in this discipline is Cristina Diezhandino, who took on the global Chief Marketing Officer role in 2020 after a long career running individual brand portfolios at Diageo and at Procter & Gamble before that. Diezhandino is, by reputation in the trade press and by her own public statements at industry conferences, deeply financially literate — comfortable presenting brand investment cases to the Diageo board and to the equity analyst community in language that those audiences can interrogate.

This is the situation: a large publicly-listed consumer goods business, with all the structural pressures to cost-cut its way to short-term margin improvement, but staffed at the top with executives who have made the institutional commitment that brand investment will not be the variable that gets cut to make a quarter's numbers.

The Decision

There was, again, no single decision. There was a sustained organisational commitment to a particular operating principle — that A&P spending as a percentage of net sales would be held in a defended range, year after year, through cycles of growth and contraction, regardless of the short-term P&L impact.

The numerical commitment was approximately 15-16 per cent of net sales for advertising and promotion. This is a remarkable number for several reasons. It is roughly double the comparable ratio at AB InBev during the same period. It is among the highest in the global consumer staples sector. And it has been remarkably stable over more than a decade — varying within a narrow band rather than being dialled up and down with quarterly margin pressure. In an industry where the typical CFO instinct in a difficult quarter is to "rebase" marketing spending temporarily, Diageo's institutional discipline has been to hold the ratio.

This commitment was tested twice in the most acute possible way. The first test was the 2008-2009 global financial crisis, when consumer spending across the developed world contracted sharply and most consumer goods CFOs were under pressure from boards to cut discretionary spending immediately. Diageo, then under Paul Walsh's leadership, maintained A&P investment through the recession. The Johnnie Walker "Keep Walking" campaign — first launched in 1999 by the agency Bartle Bogle Hegarty as an integrated global brand platform — continued to receive commitment through the worst of the recession years. The decision was made explicitly: the brand was an asset whose investment level should not be governed by short-term economic conditions.

The second and harder test was 2020. The COVID-19 pandemic destroyed the on-trade channel — bars, restaurants, hotels, airports, duty-free. Diageo, with significant exposure to on-trade volume in markets like the UK, Ireland, and travel retail, suffered a sharp revenue decline. Net sales for fiscal 2020 (ending June 2020) fell to £11.75bn from £12.87bn the year before, and operating profit fell from £4.04bn to £2.13bn. By the conventional CFO playbook, marketing spend should have been cut hard, fast, and visibly. The company should have "right-sized" its A&P investment to the new revenue base.

It did not. Diageo maintained A&P at approximately 15 per cent of net sales for fiscal 2020 — meaning the absolute marketing budget came down with revenue, but the ratio was preserved. More importantly, the strategic brand-building campaigns continued. Johnnie Walker continued to invest. Guinness continued its long-running brand work, including the celebrated 2020 "Welcome Back" campaign as pubs reopened, which became one of the most-praised brand films of the pandemic era. Don Julio and Casamigos — both relatively new to the Diageo portfolio at the time — were invested in aggressively as the at-home tequila category exploded during lockdowns. The marketing function was treated as a capability that would be needed when the recovery came, not as a cost centre to be minimised during the contraction.

The institutional mechanism that made this discipline possible is worth describing in detail, because it is the operational implementation of what F9-08 will describe as the evidence-based Marketing Finance Director's role. Diageo runs a process internally referred to (in IPA case studies and conference presentations) as the "marketing growth model" — a structured methodology for evaluating marketing investment that combines short-term ROI measurement with long-term brand equity tracking. The short-term ROI side uses econometric marketing mix modelling to measure the in-period sales response to specific campaign investments. The long-term brand equity side uses tracking studies (Diageo has historically used multiple tracker providers including Millward Brown / Kantar) to measure mental availability, brand consideration, and equity health metrics over multi-year horizons.

Crucially, both of these measurement systems are presented to the Diageo board as joint inputs to the brand investment decision, and both are presented to equity analysts in investor calls as evidence of marketing productivity. Menezes spoke routinely on quarterly calls about marketing efficiency, but he also spoke routinely about brand health metrics, and about long-term consideration scores, and about share-of-voice positions in priority categories. The financial community had been trained, over years of consistent communication, to take both kinds of evidence as legitimate and to evaluate Diageo's marketing investment on both axes.

This is what makes the Diageo discipline different from the AB InBev model. AB InBev gave the marketing function only one language with which to defend its budget — the language of immediate quarterly response. Diageo gave its marketing function two languages, and made both of them legitimate inside the financial-decision architecture. When the CFO asked "what is this campaign producing for us?" the brand team could answer in marketing-mix-model in-period response terms (the answer the CFO was used to hearing), but they could also answer in terms of three-year brand equity trajectory (the answer that protected long-term investment from short-term volatility). Both answers were considered valid. The argument did not have to be won every quarter, because the long-term framing was already institutionally accepted.

The Data

The financial outcome of this discipline is the part of the case that ends the argument with skeptical board members and CFOs who want to know whether protecting brand investment is actually compatible with shareholder return.

Metric	Diageo, fiscal 2013 (Menezes start)	Diageo, fiscal 2023 (Menezes end)
Net sales	£11.4bn	£17.1bn
Operating profit	£3.5bn	£4.6bn
A&P spend	~£1.7bn	~£2.6bn
A&P as % of net sales	~15%	~15%
Total shareholder return (10-year annualised)	—	~9% (vs ~5% FTSE 100)
Johnnie Walker volume growth (period)	—	~40% (Menezes tenure)

A few of these numbers warrant unpacking against the AB InBev comparison.

The A&P ratio held essentially constant at approximately 15 per cent of net sales across the entire ten-year Menezes tenure. This is the central data point of the case. It survived the post-2008 hangover years, the Brexit-related currency volatility, the 2020 pandemic revenue collapse, and the post-pandemic inflation environment. In each of those moments, the institutional pressure inside a consumer goods company would have been to cut marketing temporarily to protect short-term margin. Diageo did not. The discipline held.

Net sales grew 50 per cent over the decade. Operating profit grew approximately 30 per cent. Earnings per share grew in line. The total shareholder return over Menezes's tenure significantly outperformed the FTSE 100, and outperformed the global staples sector index by a meaningful margin. The simple reading: holding A&P investment at a defended ratio did not damage shareholder return. It was associated with shareholder return outperformance.

Johnnie Walker volume grew approximately 40 per cent under Menezes. This is the single most important brand-level data point in the case, because it is the longest-running test of the "Keep Walking" platform's effectiveness. The campaign, originally launched in 1999, was already over a decade old when Menezes became CEO. Most CMOs would have replaced it. Most CFOs would have argued that a fourteen-year-old campaign must be exhausted. The Diageo discipline held: "Keep Walking" continued to receive investment, and continued to produce volume growth, which eventually produced one of the longest-running and most-cited examples in IPA Effectiveness Awards history of long-term brand-building paying off in compound shareholder value.

The contrast with AB InBev's data is the part of the case that hits hardest. AB InBev's flagship brands lost share over the same decade Diageo's flagship brands gained it. The two companies had structurally similar industries (mature, consolidated, global, mass-market alcoholic beverages with a premium-tier strategy), structurally similar competitive pressures, structurally similar capital market constraints. The variable that distinguished them was the marketing investment discipline. Holding A&P at 15 per cent of net sales is not a magic formula — but the institutional commitment to defending that ratio against quarterly pressure is the operational pattern that explains the divergent outcomes.

Metric	Diageo (decade)	AB InBev (decade)
A&P as % of revenue	~15% (held)	~12% → ~7% (declining)
Flagship brand trajectory	Johnnie Walker +40%	Budweiser declining, Bud Light losing #1
Total shareholder return vs index	Outperformed FTSE 100	Underperformed
Net debt at end of period	Manageable	Required dividend cut to manage

The Marketing Finance Lesson

Diageo is the case that validates the central optimistic claim of the F9 module: that public-company marketing discipline of the kind described in F9-06 and F9-07 is genuinely possible. The pessimistic reading of marketing finance is that quarterly capital markets always defeat long-term brand investment, that the CFO always wins in the end, and that the marketer's job is fundamentally compromised by the time horizons of public ownership. Diageo is the empirical refutation. The company is publicly listed, accountable to the same analyst community as everyone else, subject to the same dividend pressures, the same competitive pressures, the same shareholder activism pressures — and yet has maintained a marketing investment discipline that would be the envy of most marketers in any sector.

The lesson the case teaches about F9-05 (budgeting methods) is that the right budgeting structure for brand investment is not zero-based and not annual. It is ratio-anchored and multi-year. The discipline of "A&P at 15 per cent of net sales, defended through cycles" is fundamentally a different operating principle than ZBB. It says: this is the level of investment our brand portfolio requires to maintain its mental availability and category position, calibrated as a fraction of the revenue base, and we will not allow short-term pressure on the income statement to push it below this level, because doing so would damage the long-term asset. It is closer in spirit to a percentage-of-sales rule with strategic exceptions than it is to ZBB. And it is closer still to the SOV-anchored approach that F9-05 will describe — the idea that marketing investment should be set primarily in relation to share-of-voice targets in the categories where you compete, which in turn determine the absolute spend level required.

The lesson on F9-06 (the business case for marketing investment) is the case that brand investment can be genuinely defended to capital markets if you have the language. Menezes did not protect Diageo's marketing investment by hiding it from analysts or by burying it in operating expenses. He defended it openly, in plain language, on quarterly calls, with metrics. He talked about brand equity trends. He talked about share of voice. He talked about long-term consideration scores. And the analyst community accepted these as legitimate inputs to its valuation models, because Diageo had spent years training the community to take them seriously and because the financial outperformance vindicated the framing. The business case for marketing investment, the case shows, is not made once a decade in a strategy review. It is made every quarter, in every interaction with the financial community, by treating brand metrics as first-class evidence rather than as marketing-team self-justification.

The lesson on F9-07 (brand as a balance sheet asset) is the most subtle. Diageo's brands appear on the balance sheet at substantial book values — Johnnie Walker, Guinness, the various legacy brand acquisitions all carry intangible asset values in the tens of billions of pounds. Unlike AB InBev, where the gap between accounting brand value and economic brand value widened steadily as brands were under-invested, at Diageo the two values have stayed broadly aligned. The accounting value reflects a brand portfolio that is genuinely producing the future cash flows the carrying value implies, because the investment to maintain those cash flows has been continuously made. There has been no Diageo equivalent to the Kraft Heinz $15bn writedown (case 5 of this module), and there is unlikely to be one, because the underlying asset has not been silently liquidated.

The lesson on F9-08 (the evidence-based capstone) is that this is what the institutional evidence-based marketing finance director looks like at scale. Not a single heroic individual, but a culture: a CMO who speaks finance, a CEO who speaks marketing, a CFO who has been trained to hear brand health as legitimate evidence, a board that understands that the A&P ratio is not a discretionary budget line but a strategic commitment, and a shareholder communications discipline that builds the legitimacy of marketing investment in the financial community over years rather than fighting for it in single annual battles.

The synthesis

The Diageo case is the only one in the F9 module where the The synthesis is straightforwardly affirmative. Diageo is, structurally, a Both/And organisation. It does not pretend that financial discipline and brand investment are in opposition, and it does not pretend they are the same thing. It treats them as two complementary commitments that have to be held simultaneously, with different operational methods, by different people, against different metrics, but inside a unified strategic framework.

The Both/And of Diageo is visible at every level. At the top, Menezes and his successors hold both the financial discipline and the marketing investment commitment in the same brain. At the CMO level, Diezhandino can speak the language of econometric marketing mix modelling and the language of brand equity tracking with equal fluency, and can present both to the board as joint inputs to investment decisions. At the brand-team level, brand managers are accountable to both short-term in-period marketing ROI metrics and long-term brand health metrics, and the two are not allowed to compete for primacy. At the financial-communications level, the company has trained its analyst audience to read brand metrics as legitimate evidence of value creation alongside the conventional financial outputs.

This is harder to do than it sounds, and it took Diageo more than two decades of institutional commitment to achieve. The "Keep Walking" campaign has now run for over twenty-five years, through five different CEOs, multiple agency relationships, currency cycles, recessions, and a global pandemic. That kind of continuity is not the product of an unusually principled marketer. It is the product of a budgetary architecture and a board culture that has institutionalised the principle so deeply that no single quarter's pressure can reverse it. The discipline is in the structure, not in the individuals.

The evidence-based Marketing Finance Director that F9-08 builds toward is, in effect, the Diageo executive at every level. The CFO who treats brand investment as capital allocation rather than expense management. The CMO who can defend that allocation in the language of shareholder return. The CEO who refuses to allow the annual budget process to override the multi-year brand commitment. The board that asks about brand health metrics as routinely as it asks about cash flow conversion. None of this is glamorous. None of it produces a heroic single-decision moment of the kind the Airbnb case provides. But it is the architecture that makes the long-term commitment survive, and the architecture is what the F9 module exists to teach.

The contrast with AB InBev is the diagnostic point. Both companies operate in adjacent alcoholic beverages categories. Both face the same kind of financial market scrutiny. The variable that distinguishes them is the institutional architecture for marketing investment. Diageo built one. AB InBev did not. The downstream consequences are visible in flagship brand trajectories, in market share data, and in total shareholder return over a decade. The The synthesis of marketing finance is not a set of philosophical commitments. It is a description of an organisational design — and Diageo is the worked example.
