Australian Serial Acquirers: Only 4 of 14 Earn Above Cost of Capital
[Part of our Global Serial Acquirer Scorecard]
Key Finding: Only 4 of 14 Australian serial acquirers earn above 12% ROIC. Zero companies sit in the 10-12% borderline — the only market in our 14-country screen with no Tier B names. Australia is polarized: genuine competitive advantage or outright value destruction, with nothing in between. Cross-border acquisitions are the dominant failure mode.
We screened 14 Australian serial acquirers by return on invested capital. Four earn above a 12% cost of equity. Six earn between 5% and 10%. Four destroy value below 5%. The gap between Tier A and the rest is not gradual — it is a cliff. No borderline cases exist.

Tier A: 4 companies (29%). Tier B: 0 (0%). Tier C: 6 (43%). Tier D: 4 (29%).
Zero Tier B companies. No market in our 14-country screen shares this feature. Australian acquirers are polarized: either genuine competitive advantage or not. No borderline cases.
The Four That Work
All four Tier A names share one trait: low goodwill. Average GW/TA across the four is 13%. Average across the Tier C/D names is 32%. The discipline gap is visible on the balance sheet.
Technology One — 29.6% ROIC with 10% GW/TA and 10% (GW+Int)/TA. A SaaS compounder earning 29.0% operating margins with near-zero acquisition dependency. This is not a serial acquirer in the traditional sense — it is an organic grower that happens to appear in acquirer screens. The 29.6% ROIC is the highest non-US figure in our 14-market universe. Down 52.2%, which is a drawdown more typical of Tier D names.
Wesfarmers — 15.4% ROIC with 13% GW/TA and 18% (GW+Int)/TA. A conglomerate that actually allocates capital well. Exited coal, bought Kidman Resources for lithium, divested Coles. Operating margins of 8.4% are modest, but the disciplined goodwill level means those margins convert to strong ROIC. Down just 33.5% — one of the shallowest drawdowns in the Australian universe. The market recognizes the discipline.
Breville Group — 13.3% ROIC with 24% GW/TA and 30% (GW+Int)/TA. Product-led acquirer in kitchen appliances. Operating margins of 12.2% on a moderate goodwill base. Down 48.5%.
ARB Corp — 13.1% ROIC with 5% GW/TA and 7% (GW+Int)/TA. The lowest goodwill in the Australian universe. ARB grows primarily organically within 4x4 vehicle accessories — a niche with pricing power and distribution moats. Operating margins of 17.8% are second only to Technology One among the Tier A group. Down 52.6%.
The Goodwill Cliff
Every Australian company with GW/TA above 40% earns below cost of capital. No exceptions.
| GW/TA > 40% | ROIC | Op Margin | Above CoC? |
|---|---|---|---|
| Worley (50%) | 5.3% | 5.8% | No |
| IPH Limited (48%) | 6.1% | 18.2% | No |
| Steadfast (42%) | 7.8% | 38.5% | No |
| AUB Group (42%) | 5.9% | 16.8% | No |
Zero of four earn above cost of capital. A perfect failure rate. Steadfast’s 38.5% operating margin is the highest of any company in the >40% GW/TA group across all markets we screen — still insufficient. When the goodwill denominator is this large, exceptional margins cannot generate adequate ROIC.
One-Deal Destroyers: Australia’s Defining Failure Mode
Three companies in the Tier C band share the same disease: a single cross-border acquisition that destroyed returns. This is Australia’s dominant failure pattern — unique in severity among the markets we screen.
CSL + Vifor (2022) — ROIC compressed from 15%+ to 8.9%. The largest deal in Australian biotech history loaded goodwill onto an otherwise capital-light business. Combined (GW+Int)/TA sits at 41%. Operating margins of 19.2% remain strong, but they service a balance sheet that more than doubled in goodwill. If Vifor integration lifts ROIC back above 12%, CSL returns to Tier A. If not, this is a permanent compression.
Reece + MORSCO (2018) — ROIC crashed from Tier A to 5.4%. A US plumbing distribution acquisition in a commoditized market. GW/TA doubled. Combined (GW+Int)/TA now sits at 54% — more than half the balance sheet is acquisition-related. Operating margins collapsed to 2.1%, the lowest of any company outside Tier D. Down 64.8%, the deepest drawdown in the Australian universe.
Worley + Jacobs ECR (2019) — Doubled the company. ROIC never recovered. GW/TA at 50% — the highest in the Australian universe. Operating margins of 5.8% on a balance sheet that is half goodwill. Down 31.9%.
All three were cross-border deals. All three doubled or tripled the acquirer’s goodwill. Australia’s AUD 2.7T GDP constrains domestic deal flow, pushing acquirers offshore for transformative transactions. The hit rate on those offshore deals is zero in our sample.
Roll-Up Decay
IPH Limited — ROIC from 29% to 6.1% over a decade of IP services acquisitions. GW/TA at 48%, combined (GW+Int)/TA at 75% — only 25% of assets are tangible. Operating margins of 18.2% are strong, but the goodwill base has consumed all returns. Down 61.2%.
AUB Group — ROIC declining steadily since 2016 as insurance broker acquisitions dilute returns. GW/TA at 42%, combined (GW+Int)/TA at 55%. Operating margins of 16.8%. Down 37.8%.
Kelly Partners — Accounting firm roll-up. Operating margins of 19.3% but ROIC of just 1.9%. Growth consumes all returns. GW/TA at 30%, combined (GW+Int)/TA at 51%. Down 58.0%.
The Standout: Technology One
Technology One earns 29.6% ROIC with 10% GW/TA. This combination — highest ROIC, lowest goodwill intensity — makes it the cleanest compounder in the Australian universe. The SaaS model generates 29.0% operating margins on a balance sheet that barely carries acquisition premiums. It is the Australian equivalent of Constellation Software’s capital efficiency at smaller scale.
The -52.2% drawdown for a company earning 29.6% ROIC is the kind of dislocation our framework is designed to identify. Most names in the Australian universe with drawdowns this deep — DOW (-53.2%), KPG (-58.0%), IPH (-61.2%), RHC (-61.5%), REH (-64.8%) — earn below cost of capital.
The Cautionary Tale: Reece
Reece was Tier A before 2018. Then it bought MORSCO — a US plumbing distributor — and ROIC crashed to 5.4%. Operating margins fell to 2.1%. Combined (GW+Int)/TA rose to 54%. The drawdown of -64.8% is the worst in Australia.
This is the one-deal destroyer in its purest form. A single cross-border acquisition in a commoditized market transformed a high-returning domestic business into a capital-destroying international one. The domestic Australian plumbing distribution business was good. The decision to go offshore was not.
Cross-Market Context
| Metric | Australia (14) | US (16) | Sweden (24) | Canada (13) |
|---|---|---|---|---|
| Above 12% ROIC | 4 (29%) | 6 (38%) | 6 (25%) | 2 (15%) |
| Below 5% ROIC | 4 (29%) | 0 (0%) | 9 (38%) | 7 (54%) |
| Avg GW/TA | 25% | 43% | 34% | 26% |
| Avg Op Margin | 15.5% | 22.4% | 8.8% | 12.5% |
| Worst drawdown | -64.8% REH | -55.6% TYL | -61.8% VIT-B | -94.5% DND |
Australia sits middle-of-the-pack on Tier A at 29%, with moderate average GW/TA of 25%. Operating margins of 15.5% tie with Switzerland for second-highest behind the US. The 29% Tier D rate is driven entirely by one-deal destroyers and commodity-adjacent conglomerates.
The comparison with Canadian Serial Acquirers is instructive. Canada has a worse Tier D rate (54%) and a worse worst-case drawdown (-94.5% DND), but both markets share the same structural problem: small domestic economies that push acquirers into cross-border deals with poor hit rates.
Sweden has a lower Tier A rate (25%) but a much larger sample (24 companies). Sweden’s failure mode is different — crowded domestic competition for targets drives up acquisition multiples. Australia’s failure mode is geographic: acquirers go offshore and overpay.
What to Look For in Australian Serial Acquirers
Four filters for this market:
- Check the cross-border exposure. Every major Australian one-deal destroyer — Reece, CSL, Worley — failed on a cross-border acquisition. If a company’s largest deal is offshore, evaluate the target market’s competitive dynamics separately. Commoditized US distribution (MORSCO) is not Australian plumbing distribution.
- Demand GW/TA below 40%. All four companies above 40% GW/TA in Australia earn below cost of capital. No exceptions. Steadfast’s 38.5% operating margins cannot overcome 42% goodwill intensity.
- Separate commodity cyclicality from acquisition failure. Seven Group (4.4% ROIC) and Downer Group (3.4% ROIC) are commodity-adjacent. Their ROIC volatility reflects mining and infrastructure cycles, not acquisition discipline. Do not treat cyclical troughs as permanent impairment — but do not excuse chronic underperformance as cyclicality.
- Watch the combined intangible ratio. GW/TA understates the real acquisition load for several names. IPH’s 48% GW/TA becomes 75% at (GW+Int)/TA. Reece’s 21% becomes 54%. CSL’s 21% becomes 41%. The combined ratio tells the true story.

- Tier classification: A (>12%), B (10-12%), C (5-10%), D (<5%).
- Data as of: February 2026.
Technology One and ARB Corp are primarily organic growers; we include them because they are frequently grouped with Australian serial acquirers and meet our screening criteria. Seven Group drawdown is unavailable due to data limitations.
Mauboussin & Callahan (2023) found median ROIC of 9.5% for the Russell 3000.1 Our Australian universe shows 10 of 14 companies (71%) below this threshold — a failure rate consistent with the global serial acquirer pattern.
