For two decades, executives have been told the same story about enterprise value creation: build a bigger, more connected, more resilient supply chain network and the financial returns will follow. Scale your supplier base. Deepen your customer relationships. Embed yourself in the network. The reasoning sounds airtight — better networks should mean better margins, better valuation, better shareholder returns.
A recent study published in Business Strategy and the Environment, covering more than 16,000 firm-year observations across 3,028 publicly traded U.S. companies from 2005 to 2021, looked at whether that story actually holds up. Mostly, it doesn’t.
The headline finding is one of the most useful pieces of research I’ve read on enterprise value creation in years, and almost nobody is talking about it the right way. Here’s what the data actually shows: a larger supply chain network does not, by itself, meaningfully improve return on assets, return on equity, Tobin’s Q, or stock returns. The only direct financial benefit is a small lift to operating margin (return on sales). Everything else – the part that actually moves shareholder value – is roughly neutral.
The story doesn’t end there. The research identifies a hidden channel through which supply chain networks do create enterprise value. And it’s not the one most operators are managing toward.
What the data actually shows
The researchers tested three things, in sequence. First, does network size and centrality directly improve ESG performance? Second, does it directly improve financial performance? Third – and this is where it gets interesting – does it improve financial performance indirectly, through ESG?
The answers were: yes, mostly no, and yes.
Larger and more central supply chain networks produce significant improvements in ESG scores, with the strongest effect on the environmental pillar specifically. That part is intuitive: more connections mean more pressure to coordinate sustainability standards, more visibility into supplier practices, more diffusion of best practices across the network.
But when the researchers tested whether those same network characteristics directly drive financial outcomes, the results were striking. Across return on assets, return on equity, market valuation, and stock returns, the direct effect was statistically indistinguishable from zero. The only metric that responded was operating margin — and even that effect was modest in economic terms.
The third test is where the real signal lives. Using a simultaneous-equations model, the researchers found that supply chain network position does enhance firm value — but only when it travels through measurable ESG performance. The financial benefit is real. It just doesn’t arrive directly. It arrives because the market reads ESG performance as a quality signal, and a well-structured network produces stronger ESG signals – which leads to enterprise value creation.
That’s the hidden channel. Network → ESG performance → market signal → enterprise value creation.
Why bigger networks don’t automatically create value
The mechanism behind the no-direct-effect finding is the part most executives skip past. It’s worth slowing down on.
Bigger networks come with real costs:
- IT and information systems investment to manage network complexity
- Coordination overhead across more suppliers, customers, and tiers
- Monitoring costs for compliance, quality, and continuity
- Systemic risk exposure — when one node in your network has a problem, you have a problem
The research suggests that investors see this trade-off clearly. They recognize that a bigger network creates operational efficiency on one hand and coordination cost plus risk exposure on the other. The two largely cancel out at the level of broad financial metrics. ROA doesn’t move because the asset base required to support a bigger network grows alongside the operational gains. ROE doesn’t move because the equity exposure rises alongside the returns. Tobin’s Q doesn’t move because the market is pricing both the upside and the downside.
This is the part the consulting playbook tends to ignore. “Build a more resilient supply chain” sounds like an unambiguously good idea. But resilience-by-expansion is expensive, and expansion alone doesn’t pay for itself in the metrics that determine enterprise value creation.
What pays is when the expansion produces something the market can read as a credible signal of underlying business quality. Right now, that signal is ESG performance – particularly environmental performance, which is the pillar most directly tied to supply chain operations.
The enterprise value creation question most executives manage wrong
Here’s where the practical implication starts to bite.
If you’re running a Fortune 1000 company, or a PE-backed industrial business, or any enterprise with a significant supply chain footprint, the question you’ve probably been asking is: how do we make our supply chain more efficient, more resilient, more diversified? Those are reasonable questions. But they’re not the questions that connect supply chain investment to enterprise value creation.
The question that actually matters is: how do our supply chain decisions translate into signals the capital markets price?
That’s a fundamentally different framing. It moves supply chain out of the operations silo and into the cross-functional zone where strategy, sustainability reporting, investor relations, and capital allocation intersect. Most enterprises are not organized to answer this question. Procurement reports to operations. Sustainability reports to corporate affairs or legal. IR reports to the CFO. Each function optimizes locally and produces metrics that look clean inside its own domain.
The hidden channel runs between those functions, not within any of them.
This is why the same supply chain investment can produce wildly different enterprise value outcomes at two otherwise similar companies. Company A expands its supplier base, builds redundancy, adds tier-2 visibility — and the market sees a more complex, more expensive operation with no clear signal benefit. Company B makes nominally similar investments but ties them to disclosed environmental performance improvements, supplier audit programs, and sustainability metrics the market can verify — and the same operational moves now produce a measurable lift in valuation.
The difference isn’t in the supply chain. It’s in whether the supply chain is being managed as a stand-alone optimization problem or as a component of a coordinated enterprise value system. It’s the same lens we applied in our breakdown of the Harley-Davidson turnaround — where the decisive moves weren’t inside any single function, but in how the functions were being read together.
What this means for how operators should think
A few practical takeaways from the research that I’d put in front of any executive team looking at supply chain investment:
Stop evaluating supply chain decisions on operational metrics alone. Operating margin will reward you. Asset returns won’t. Market valuation won’t. If your supply chain capex is being justified solely on cost-out or resilience grounds, you’re optimizing for the part of the financial story that doesn’t move enterprise value much.
Look for the signal layer, not just the operational layer. Every supply chain investment has two outputs: an operational one and a signal one. The signal one is what reaches investors, lenders, and rating agencies. Ask explicitly: what does this investment let us say about ourselves that’s both true and credible?
Treat ESG performance as infrastructure, not reporting. The research is clear that ESG is the transmission channel, not a side activity. That means ESG measurement and disclosure capability is part of the core operating system of an enterprise that wants supply chain investment to translate into shareholder value — not a compliance overlay.
Recognize that the financial benefit is indirect, which means it’s slow. A new supplier diversification initiative doesn’t produce a Tobin’s Q lift in quarter one. It produces ESG improvements that, over time, reduce information asymmetry between the firm and the market. Boards and management teams need to be patient with the lag — and skeptical of any pitch that promises a direct, fast-acting financial return from network expansion alone.
The system-level question that determines enterprise value creation
The research is, on its surface, a study of supply chain economics. But the deeper finding is something broader, and it’s the part that matters most for how enterprises actually create value.
Function-by-function optimization doesn’t produce enterprise value. The value is created in the connections between functions — the channels through which operational decisions become market signals, through which capital allocation becomes strategic positioning, through which supplier networks become sustainability credibility. Those channels are mostly invisible on an org chart and mostly absent from quarterly metrics. They’re also where the actual money is.
This is why supply chain optimization, as a stand-alone discipline, has hit diminishing returns. The next layer of enterprise value creation isn’t about making any individual function better. It’s about diagnosing where value is actually being created or eroded across functional boundaries — and managing the transmission channels that turn operational reality into market valuation.
That’s a different kind of question than most enterprises are equipped to answer. It requires a system-level view of how decisions in one part of the business affect outcomes in distant parts. It requires explicit modeling of indirect effects, not just direct ones. And it requires a discipline of asking, before any major operational investment: what’s the channel through which this becomes enterprise value, and is that channel actually open?
This is the territory the Enterprise Value Creation Roadmap is built for. It’s not a supply chain tool. It’s a diagnostic for the cross-functional channels — the places between operations, strategy, capital, and signaling — where enterprise value either compounds or dissipates. The supply chain research is one example of why that lens matters. There are dozens of others hiding inside any enterprise of meaningful size. The companies that find them, and manage them deliberately, are the ones whose operational investments actually translate into shareholder value. The ones that don’t are the ones quietly wondering why a decade of supply chain optimization didn’t move the needle.
The hidden channel was always there. The research just made it visible.
