Key Finding: We screened 187 serial acquirers across 14 markets. Only 59 — one in three — earn above a 12% cost of equity with goodwill in the denominator. Above 40% GW/TA, 76% destroy value. Six metrics separate the compounders from the destroyers. Every one of them is public data.
Part of our Global Serial Acquirer Scorecard
Most serial acquirer analysis starts in the wrong place. Analysts focus on deal count, acquisition pace, revenue growth, and management’s track record. These are the metrics that make for good presentations. None of them predict whether a company creates or destroys value.
We ranked 187 serial acquirers across 14 markets by return on invested capital with goodwill in the denominator. The data reveals a consistent pattern: the firms that look most active — the most deals, the highest revenue growth, the most acquisitive cultures — are often the worst capital allocators. The firms that create value tend to look boring, acquire infrequently, and run tight balance sheets.
Here is the six-step process we use to evaluate any serial acquirer, with real companies and real numbers at every step.
Step 1: Calculate ROIC With Goodwill in the Denominator
The single most important decision in serial acquirer analysis is what you put in the denominator.
Most financial data providers show return on equity or return on tangible capital. Both strip out goodwill. Goodwill is the premium paid above book value in every acquisition. Remove it from the denominator and a company that paid 3x book value for a target looks identical to one that built the same business organically. That distortion is how bad acquirers hide.
We put goodwill back in. The formula:
ROIC = NOPAT / (Equity + Debt - Cash)
Goodwill stays in. Every acquisition premium stays in. The denominator grows with every deal paid above book value.
Worked example — Roper Technologies vs Illinois Tool Works:
Roper Technologies (US) earns 28.4% operating margins — outstanding by any standard. With goodwill in the denominator, and Roper carries 62% GW/TA, ROIC is 6.2%. A company that appears to be a margin machine earns 6 cents on every dollar shareholders have invested, including every acquisition premium Roper ever paid.
Illinois Tool Works runs similar margins (26.8%) and carries 32% GW/TA. ROIC: 30.8%. ITW stopped making acquisitions around 2012 and focused on organic improvement through its 80/20 process. From 2012 to 2025, GW/TA stayed flat at 32% while ROIC climbed from 19.4% to 30.8%. The best serial acquirer in the US is the one that stopped serial acquiring.
The threshold: We use 12% as our cost of equity proxy. This is conservative — most serial acquirers carry higher equity risk than the broad market. Mauboussin & Callahan (2023) demonstrated that ROIC correlates r=0.58 with value creation, rising to r=0.78 when combined with growth. Companies earning below their cost of capital are worth less than book regardless of how fast they grow. For 128 of 187 companies in our screen, the ROIC with goodwill test produces a failing grade.
| ROIC | Tier | Interpretation |
|---|---|---|
| > 12% | A | Earning above cost of capital |
| 10–12% | B | Borderline — watch the trend |
| 5–10% | C | Destroying value |
| < 5% | D | Severe value destruction |
Step 2: Check the Goodwill-to-Total-Assets Ratio
ROIC tells you the current result. GW/TA tells you the balance sheet structure that produced it — and how much pressure future deals will add.
GW/TA measures cumulative acquisition premiums as a percentage of total assets. A rising GW/TA means each new deal adds more goodwill than tangible assets. Eventually the denominator becomes so goodwill-heavy that even strong operating margins cannot generate adequate ROIC.
The 40% cliff:
Across 14 markets and 187 companies, we identified 51 companies with GW/TA at or above 40%. Only 12 earn above 12% ROIC — a 24% Tier A rate compared to 35% for companies below the threshold.
The pattern repeats in every market:
- US: 9 of 12 companies above 40% GW/TA earn below cost of capital
- Sweden: 8 of 9 companies above 40% GW/TA earn below cost of capital
- Switzerland: 3 of 4 companies above 40% GW/TA earn below cost of capital
Worked example — Roper vs CGI Group:
Roper Technologies at 62% GW/TA earns 6.2% ROIC. The balance sheet cannot support the goodwill load, even with 28.4% operating margins. Every additional acquisition at Roper’s typical multiples adds to a denominator already too large to service.
CGI Group (Canada) also carries 60% GW/TA — and earns 12.3% ROIC, sustaining above cost of capital for over a decade. What makes CGI the exception? IT services consulting generates recurring revenue without capital intensity. Government contracts provide stability. CGI’s business model absorbs goodwill that a manufacturer or hardware distributor cannot.
CGI is why 40% is a warning sign requiring explanation, not an automatic rejection. The exceptions to the rule share a common trait: operating margins above 16% or structural moats that protect pricing power. Without one of those two properties, above 40% GW/TA is almost always fatal to ROIC.
The (GW+Int)/TA correction:
For software acquirers, GW/TA understates acquisition intensity. IFRS purchase price allocation forces software deals to classify customer relationships and technology as identifiable intangible assets rather than goodwill. Vitec Software (Sweden) carries 50% GW/TA — but its combined (GW+Intangibles)/TA is 88%. Only 12% of Vitec’s assets are tangible. The corrected metric shows why 20.9% operating margins still produce 6.3% ROIC: there is almost no tangible asset base to earn against.
| GW/TA | Signal |
|---|---|
| < 15% | Low acquisition intensity — organic grower |
| 15–30% | Disciplined acquirer — manageable goodwill |
| 30–40% | Moderate dependency — margins must compensate |
| > 40% | Heavy acquirer — 76% destroy value at this level |
Step 3: Test the Margin Cushion
Operating margins determine how much goodwill a company can carry without destroying ROIC. This is the link that most analysis misses.
Two companies can carry identical GW/TA ratios and produce radically different ROICs based solely on margin difference. The margin is what services the goodwill in the denominator.
The US model:
The US screen averages 22.4% operating margins and 43% average GW/TA — the highest goodwill intensity of any market we screened, yet a 38% Tier A rate. American serial acquirers carry enormous acquisition premiums and earn above cost of capital because wide margins absorb what would destroy a lower-margin acquirer.
TransDigm (US) earns 47.4% operating margins on aerospace components, carries 46% GW/TA, and achieves 10.7% ROIC — borderline but survivable. At 20% margins with the same goodwill load, ROIC would be approximately 4–5%. The margin is the entire difference.
The Sweden problem:
Sweden averages 8.8% operating margins and 34% average GW/TA. The combination is lethal. At 8.8% margins, a 34% GW/TA burden produces approximately 7–9% ROIC before any deal mispricing. The model fails arithmetically before management makes a single mistake.
Vitec Software is the starkest illustration: 20.9% operating margins — best in the Swedish screen — and 6.3% ROIC. High margins are necessary but not sufficient. At Vitec’s acquisition multiples (3–4x revenue implied), goodwill accumulates faster than margins can service it.
Rule of thumb from our data: To sustain 12% ROIC above a 40% GW/TA base, a company typically needs operating margins above approximately 17%. Below that threshold, the math works against the acquirer even with perfect execution. Ten of twelve companies globally that earn above cost of capital above the 40% GW/TA cliff carry operating margins of 16% or higher. The two exceptions — ISS (Denmark, 4.8% margins, 41% GW/TA, 21.7% ROIC) and Amadeus Fire (Germany, 12.5% margins, 52% GW/TA, 15.7% ROIC) — survive on asset-light service models where capital turnover compensates for thinner margins.
| GW/TA | Approximate Minimum Margin to Clear 12% ROIC |
|---|---|
| 20% | ~8% |
| 30% | ~12% |
| 40% | ~17% |
| 50% | ~22%+ |
These are approximations derived from our dataset, not formulas. Use them as a screen, not a guarantee.
Step 4: Read the Drawdown as a Market Verdict
The 52-week drawdown from a stock’s 5-year peak is not a valuation metric. It is a market verdict on capital allocation — and it tends to lead the financials.
Why drawdowns matter:
Markets price expected returns, not historical ones. A company whose ROIC is declining will see the stock fall before the ROIC crosses below 12%. Drawdown captures this forward-looking verdict in a single number. Our data shows a clear pattern: serial acquirers with drawdowns of 50%+ almost always have ROIC problems that either already show in the financials or will within 12 months.
Cases where drawdown preceded the ROIC collapse:
- Tyler Technologies (US): -55.6% drawdown. ROIC fell from 20%+ to 6.9% following the NIC acquisition ($2.3B, 2021). GW/TA jumped from 25% to 49%.
- Dye & Durham (Canada): -94.5% drawdown. ROIC: -9.5%. The market priced the implosion before the financials confirmed it.
- Constellation Software (Canada): -55.8% drawdown. ROIC has declined from the mid-20% range to 10.8% — no longer clearing cost of capital on our methodology.
Cases where the drawdown overshot:
Drawdowns can also overshoot. Straumann (Switzerland) — 16.7% ROIC, 24% operating margins, 16% GW/TA — trades at -58.3% from peak on GLP-1 narrative fears, while posting 10% revenue growth. M3 (Japan) earns 15.8% ROIC but sits at -87.2% from peak after investors entered at an extreme valuation.
The distinction: drawdowns caused by valuation correction or external narrative coexist with stable or improving ROIC and moderate GW/TA. Drawdowns caused by capital allocation failure accompany rising GW/TA, falling ROIC, and declining margins. Check which pattern applies before interpreting the drawdown as a buy signal.
Step 5: Assess the ROIC Trend
A single ROIC snapshot is less informative than its direction. Mauboussin & Callahan (2023) found that companies moving from the bottom to the top ROIC quintile delivered 33% compound annual TSR over three years; top-to-bottom transitions produced -11%. Direction matters more than level.
For serial acquirers specifically, the trend reveals whether each new acquisition improves or dilutes the existing capital base. A falling ROIC with an accelerating acquisition pace is the clearest possible signal of capital allocation failure.
Constellation Software’s decline:
Constellation Software (Canada) declined from mid-20% ROIC (2008–2012) to 27% (2013–2017) to 17% (2018–2020) to 10.8% today. GW/TA stayed flat at 10–11% — disciplined pricing per deal throughout. The problem is arithmetic: deploying $3B+ annually into VMS acquisitions at low multiples still compresses ROIC when the capital base reaches $18B. Scale diluted returns without any change in execution quality.
Illinois Tool Works’ improvement:
ITW’s ROIC rose from 19.4% (2012) to 23.4% (2018) to 30.8% (2025) while GW/TA stayed flat at 32%. Thirteen consecutive years of ROIC improvement by stopping acquisitions and optimizing the existing portfolio.
Indutrade’s warning:
Indutrade (Sweden) declined from 14% ROIC to 10.7% as acquisition pace increased. The company’s playbook has not changed — the issue is that quality industrial acquisitions in Scandinavia have become harder to source at acceptable prices. Multiples rose, ROIC fell. The trend signals the constraint.
| ROIC Trend | What It Means | Response |
|---|---|---|
| Improving | Each deal better than prior, or organic gains | Study what changed |
| Stable | Machine running as designed | Hold if above 12% |
| Declining slowly | Pressure building — marginal deals worsening | Investigate pipeline discipline |
| Declining fast | Capital allocation failure in progress | Exit or avoid |
Step 6: Compare to the Market Benchmark
No ROIC exists in a vacuum. A 12% ROIC in Switzerland — where 62% of serial acquirers clear that threshold — is a different signal from a 12% ROIC in Canada, where only 15% do.
Market benchmarks provide two things: a peer baseline for ROIC expectations, and context for what cost structures, acquisition targets, and deal dynamics are typical in that market.
The 14-market reference set:
| Market | Tier A Rate | Avg GW/TA | Avg Op Margin | Context |
|---|---|---|---|---|
| Switzerland | 62% | 17% | 15.5% | Organic discipline dominates |
| US | 38% | 43% | 22.4% | Margin fortress absorbs high goodwill |
| Spain | 38% | 18% | 10.3% | Capital efficiency outliers |
| Netherlands | 36% | 21% | 9.7% | Quiet achievers, lean balance sheets |
| Finland | 40% | 29% | 10.3% | Industrial moats, not primarily acquirers |
| Germany | 30% | 27% | 10.2% | Binary outcomes — highs and lows |
| Australia | 29% | 25% | 15.5% | Cross-border deals destroy value |
| Sweden | 25% | 34% | 8.8% | Overcrowded, failing model |
| Denmark | 23% | 25% | 10.3% | Turnarounds, not compounders |
| UK | 18% | 28% | 12.3% | Discipline without results |
| Italy | 18% | 21% | 11.2% | Mediocrity trap |
| France | 17% | 35% | 12.9% | Great operations, poor allocation |
| Canada | 15% | 26% | 12.5% | Model birthplace, worst outcomes |
| Japan | 50% | 11.5% | 19.1% | Adjusted for genuine acquirers: 36% |
A company earning 12% ROIC in Canada — where only 2 of 13 companies clear the threshold — invites scrutiny about why it succeeds where 85% fail. A company earning 12% ROIC in Switzerland — where 8 of 13 succeed — is the norm, not an outlier.
The Logista lesson:
Spain’s Logista earns 32.9% ROIC on 2.3% operating margins — the thinnest margins of any Tier A company across all 14 markets. Without market context, a 2.3% operating margin looks like a business to avoid. Within the Spanish screen, Logista makes sense: tobacco and pharmaceutical distribution generates enormous revenue relative to invested capital. Asset-light distribution with 12% GW/TA produces 32.9% ROIC because capital turnover, not margin, drives the numerator. Context is everything.
The Decision Checklist
Apply these six checks to any serial acquirer.
| Check | Pass Condition | Red Flag |
|---|---|---|
| 1. ROIC (with goodwill) | > 12% | < 10%, or declining trend |
| 2. GW/TA ratio | < 40%, stable or falling | > 40%, or rising quarter-over-quarter |
| 3. Margin cushion | Margins consistent with GW/TA level | Thin margins + high goodwill |
| 4. Drawdown signal | Drawdown driven by valuation, not capital failure | Drawdown coincides with rising GW/TA |
| 5. ROIC trend | Stable or improving | Declining for 3+ consecutive years |
| 6. Market benchmark | At or above market Tier A rate | Below market average by wide margin |
6 of 6 passes: Probable compounder. Hold or buy depending on valuation.
4–5 passes: Monitor closely. One deteriorating metric often precedes broader decline.
3 or fewer passes: Avoid. The probability of sustained value creation is low.
OEM International — 6 of 6:
OEM International (Sweden, OEM-B) passes all six: 26.4% ROIC, 8% GW/TA, 14.5% operating margins sufficient for that goodwill load, a -20.7% drawdown driven by Swedish market sentiment rather than operational deterioration, stable ROIC trend, and ranks first in a market where six of 24 companies clear 12%. This is what a clean analysis looks like.
Vitec Software — 1 of 6:
Vitec Software (Sweden, VIT-B) passes one: it operates in a premium-priced niche (vertical market software) that confers a structural advantage over undifferentiated acquirers. But 6.3% ROIC fails the first check. 50% GW/TA rising fails the second. 20.9% margins insufficient at that goodwill level fails the third. A -61.8% drawdown coinciding with rising GW/TA fails the fourth. A declining ROIC trend fails the fifth. One structural positive does not offset five capital allocation failures.
What Matters and What Doesn’t
What predicts value creation:
- ROIC with goodwill in the denominator
- GW/TA trend — not just the level
- Operating margin relative to GW/TA burden
- ROIC direction over a three-year minimum
What doesn’t predict value creation:
- Acquisition count or pace
- Revenue growth rate
- Management’s track record from a decade ago
- Sector reputation — even “proven” models fail (Canada’s 15% Tier A rate)
- Headline operating margins without checking the balance sheet structure
Mauboussin & Callahan (2023) found that 48% of top-ROIC-quintile companies remain there after three years — and 15% fall to the bottom. No serial acquirer’s Tier A status is permanent. The framework requires re-running against new data every year.

Methodology
Data covers 187 serial acquirers across 14 markets. ROIC sourced from QuickFS (latest fiscal year, as of February 2026) and Stock Analysis (Japan). GW/TA and (GW+Int)/TA from most recent quarterly filings. Drawdowns calculated from 5-year peaks via Yahoo Finance.
We define a serial acquirer as a listed company that has completed three or more acquisitions in the past decade and where M&A is a stated or demonstrated growth strategy. ROIC formula: NOPAT (operating income × (1 − effective tax rate)) divided by invested capital (equity + debt − cash), with goodwill included in the denominator. Cost of equity threshold: 12%, conservative for the risk profile of most serial acquirers.
