The Company Defense Shield You Cannot See

There is a useful habit in investing that can sometimes become a limitation: putting every company into a simple “moat” or “no moat” box.

The idea of an economic moat is very powerful. Warren Buffett popularised the concept as a way of thinking about the structural advantages that allow a business to protect its excess profits from competitors. A company with a very strong, wide economic moat can often raise prices, retain customers, earn high returns on capital and reinvest for many years without competitors destroying those economics.

But the real world is more complicated.

Few businesses clearly have a dominant wide or narrow economic moat, and fewer even have multiple interlocking narrow or wide economic moats. A powerful global distribution network, a legally protected technology, an extremely strong brand, very high switching costs, or a natural monopoly or oligopoly can make life very difficult for new competition with very high barriers to entry.

Many other businesses do not have one obvious economic moat, much less multiple narrow or wide interlocking economic moats. Yet some of these companies can still be strong businesses — however, not exceptional companies like high-quality stocks and great companies like true compounders — and, when purchased at a very cheap or cheap valuation, become outstanding investments.

The reason is that competitive strength does not always come from one giant wall. Sometimes it comes from a system of several smaller walls that reinforce one another.

A company may possess a very strong balance sheet, excellent capital efficiency, superior supply-chain capabilities, outstanding operating discipline, a well-known brand, excellent customer service, and an organizational culture focusing on customer satisfaction — similar to how Amazon operated in its early days under Jeff Bezos — that is very difficult to reproduce. None of these factors, considered separately, may qualify as a decisive economic moat.

Together, however, they can create something economically powerful. I call this the Compensatory Interlocking Defense Shield against competition.

The idea is simple: a company does not always need one overwhelming economic moat if it possesses many independent, durable, and mutually reinforcing strengths that collectively make it difficult for competitors to reproduce its economics.

Haidilao International Holding Ltd., the company behind the Haidilao restaurant business in Greater China and listed in Hong Kong under stock code HKG: 6862, provides an unusually useful case study.

The example needs one important clarification. Haidilao International Holding’s former international restaurant business was separated into Super Hi International Holding, which is now a separate listed company. Therefore, references to Haidilao’s restaurant network need to distinguish the HKG: 6862 business from the international business. The HKG: 6862 group reported 1,383 Haidilao-branded restaurants at 31 December 2025, consisting of 1,304 self-operated restaurants and 79 franchised restaurants, while Super Hi International reported 126 Haidilao restaurants across 14 countries outside Greater China.

That distinction does not weaken the underlying investment lesson. It makes the analysis more precise.

The Occasional Problem With Looking for One Perfect Moat

Imagine two companies.

Large-Cap Company A has one enormous advantage. It owns a technology protected by patents that competitors cannot legally copy for 20 years.

Another Large-Cap Company B has no single overwhelming advantage. Instead, it has the following.

Company A looks more obviously protected. Company B may look much less impressive if the analyst uses a simple moat checklist.

But now imagine a competitor trying to attack Company B.

It can copy the product. It can hire some of the employees. It can improve its service. It can build warehouses. It can negotiate with suppliers. It can open stores. It can advertise. Yet the competitor must reproduce all of these things simultaneously while earning an acceptable return on capital.

That is much harder.

The important question therefore changes from “What is this company’s moat?” to “What combination of strengths allows this company to defend its economics against competition?”

This is a more demanding question because it forces an investor to look at the whole business system rather than search for one fashionable characteristic. A company can have a weak or no individual moat but a very strong competitive architecture. That architecture may be sufficient to produce persistent excess returns.

Haidilao: An Unusually Useful Example

Haidilao is particularly interesting because restaurants are generally not regarded as an industry with very strong or strong structural moats.

This makes restaurants an excellent test of the compensatory-shield concept. Due to the nature of the industry, the reasons why a business like Haidilao succeeds cannot be simply explained by a patent or legal monopoly. Its competitive strength has to come from the interaction of many strengths.

The company’s 2025 results provide useful evidence.

The scale is important. But scale alone is not the argument. The more interesting question is what Haidilao does with that scale.

1. The Balance Sheet: Financial Strength as a Competitive Advantage

The first compensating strength is financial strength.

At 31 December 2025, Haidilao International reported cash and cash equivalents of approximately RMB6.60 billion, more than enough to cover total debt of approximately RMB5.93 billion. This is important because a very strong balance sheet gives a business choices.

A heavily indebted company has to think about survival. A financially strong company can think about opportunity. It can:

This does not constitute a conventional economic moat. A competitor can theoretically obtain financing. But financial strength becomes a compensating strength because it reduces the probability that the company will be forced into bad decisions when the operating environment deteriorates. It also creates strategic freedom. That matters enormously in cyclical or highly competitive industries.

The distinction is important, however. An investor should not simply compare cash with bank debt and declare the business financially risk-free. Restaurant companies have lease obligations, working-capital needs and ongoing capital requirements. Haidilao itself reports right-of-use assets under IFRS 16, reflecting its leased properties.

Therefore, the correct conclusion is: Haidilao has a very strong conventional liquidity position, rather than being completely free of financial obligations.

2. Capital Efficiency: Turning Operational Advantages Into Economic Returns

The second compensating strength is capital efficiency. This is where the analysis becomes more important for investors.

A company can have excellent service, strong branding, and huge revenue while destroying shareholder value. Revenue is not the objective. Profit is not even the ultimate objective. The long-term objective of an investor is the productive use of capital.

Return on invested capital asks a fundamental question: how much operating profit can this business generate from the capital required to operate it? Return on assets asks another: how much profit can the company generate from the asset base supporting the business?

Haidilao has historically been capable of producing attractive economic returns from its operating asset base, with a five-year average ROA above 11% and a five-year average ROIC above 16%, depending on the formula used for ROIC and ROA calculations.

That is far more important than simply saying that the company is able to defend itself from competition, as it can be considered the largest and most profitable hotpot restaurant in China by certain metrics.

The ideal combination is: high returns on capital + reinvestment opportunities + long duration. However, it is not practical to expect the ideal combination from stocks of companies without an economic moat. This is where the extensive combination of compensatory strengths becomes powerful.

The factors begin reinforcing one another.

3. Supply-Chain Capability: The Hidden Infrastructure Behind the Restaurant

The third compensating strength is supply-chain capability. This is one area where the word “dominance” should be used carefully.

As investors, it is difficult to ascertain that Haidilao completely dominates the Chinese restaurant supply chain. However, it is much more feasible to ascertain whether Haidilao possesses a supply-chain system operating at such a large scale and comprehensive level of coordination that smaller competitors may find it very difficult to reproduce economically. That distinction matters.

Restaurants sell fresh food. Fresh food creates a difficult operating problem. The company must obtain ingredients in massive quantities at acceptable prices, maintain quality, transport them, store them, distribute them, and ensure that thousands of restaurants can serve customers consistently while maintaining food standards and food safety at all times.

The larger the restaurant network becomes, the more complex this problem becomes. But scale can also turn complexity into an advantage.

A restaurant group with more locations can potentially aggregate purchasing demand. Greater purchasing volume can support better procurement. More locations can justify greater investment in distribution infrastructure. Better distribution can support more consistent food quality. Consistent quality can strengthen the customer proposition. Stronger customer demand can support additional restaurants.

This is an example of a reinforcing loop, borrowed partly from the book “The System Gambit: Find Leverage to Unlock Compounding Value” by Ritavan.

The company does not need a monopoly. It simply needs the system to become progressively harder to reproduce at comparable economics.

Haidilao’s own disclosures emphasise supply-chain management as one of the key areas controlled by its headquarters. Its international business also describes its ability to provide consistently high-quality food as depending heavily on procurement capabilities and supply networks.

This is an important insight for investors. The competitive advantage of a restaurant is not always visible to the customer. A customer sees the restaurant. The customer does not see the procurement contracts, food processing, logistics, quality controls, inventory systems, and distribution network behind the restaurant. Yet these invisible systems can determine whether the visible customer experience remains consistent.

4. Operational Excellence: The Competitive Advantage of Execution

The fourth compensating strength is operational excellence. This may be Haidilao’s most visible strength.

Haidilao is known for excellent customer service, employee training, restaurant management and attention to the dining experience. Its business model includes standardised operations, employee training, food-safety controls, service-quality management and supply-chain management.

The fact that Haidilao’s managers are almost all from internal promotion deserves attention. If sustained for decades, such a system can create several advantages.

This creates something economically interesting: the workforce itself becomes part of the company’s organizational capital. That is difficult to capture on a conventional balance sheet. A business can copy a procedure. It is much harder to copy an organisational culture.

A competitor can write a manual saying “treat customers exceptionally well.” That does not mean the competitor will actually deliver exceptional service across hundreds or thousands of restaurants. Execution requires:

This creates another reinforcing loop, again borrowed partly from the book “The System Gambit: Find Leverage to Unlock Compounding Value” by Ritavan.

The resulting advantage may be invisible on a balance sheet. It can nevertheless be economically real.

5. Customer Service Becomes an Economic Asset

Customer service is sometimes dismissed as a “soft” strength. That is a mistake.

A business exists because customers choose to give it money. If customer service increases customer satisfaction, repeat visits, and willingness to recommend the restaurant, it has direct economic value.

Haidilao’s 2025 disclosures describe a wide range of service practices intended to create a memorable dining experience. These include waiting-area services, personalised assistance, birthday celebrations and other forms of customer care.

The important question is not whether every service gesture can be copied. Almost all can. The question is whether competitors can copy the entire operating system that delivers those services consistently at scale. That is considerably more difficult.

This is the heart of the compensatory-strength-defense-shield idea. A single service feature is weak. A service culture supported by training, incentives, management systems, brand recognition, supply-chain consistency, and store-level processes can be much stronger.
