HORIZONTAL INTEGRATION
Definition
Horizontal integration is a growth strategy through which a company expands its business by acquiring or partnering with competitors operating at the same stage of the value chain
In retail, this can take the form of a store chain acquisition, a joint purchasing group, or a commercial alliance
In terms of pricing, horizontal integration offers significant opportunities: greater bargaining power with suppliers, the pooling of pricing tools, and the potential for harmonizing pricing strategies.
75 stores, gross margin up 2.1% over 12 months
Merger of two regional home improvement chains (40 + 35 stores)
additional discount secured from the main supplier thanks to the purchasing power of the new headquarters (75 stores, €480 million in revenue).
Gross margin over the 12 months following the merger
Average traffic over the 12 months following the merger
Why it matters
- Increase bargaining power upstream —with suppliers—which leads to better purchasing terms and, consequently, additional profit margins or more competitive selling prices.
- Pool fixed costs (centralized purchasing, logistics platform, pricing tools) across a broader scope.
- Harmonize pricing practices across integrated entities to avoid conflicting arbitrage opportunities in shared markets.
Real-world example
Two regional home improvement chains, operating 40 and 35 stores, respectively, in non-competing regions, are merging
The resulting entity comprises 75 stores and €480 million in revenue. With its main tool supplier, the new central purchasing organization secured an additional 1.8 percentage points discount on purchasing terms, which is split between a 0.9 percentage point increase in gross margin and 0.9 percentage points reinvested in price reductions on key product categories. The results over 12 months: a 2.1% increase in gross margin and a 4.5% increase in average customer traffic.
How to measure and use it
To take advantage of horizontal integration in pricing, three steps are required: audit current price discrepancies between the merged entities, renegotiate supplier contracts based on the new consolidated market position (often within the first few months), and gradually unify pricing tools to avoid maintaining two systems in parallel
The challenges of change management are significant: the pricing teams of the merged entities must learn to work together and reach joint decisions.
Common pitfalls
- Rushing the harmonization of rates: before fully understanding the specific characteristics of each entity (market positioning, customer base, local competition).
- Underestimating IT complexity: IT system unification can take several years and cause operational friction.
- Ignoring change management: Poorly supported integration leads to the departure of key experts and undermines pricing performance.
FAQ
Horizontal integration is a growth strategy in which a company expands its business by acquiring or forming partnerships with competitors operating at the same stage of the value chain. In the retail sector, this can take the form of a store chain acquisition, a joint purchasing group, or a commercial alliance.
Renegotiating supplier contracts can begin in as little as 3 to 6 months
Standardizing tools takes 12 to 24 months, depending on the complexity
Cultural alignment (work styles, metrics) often takes 2 to 3 years.
Not necessarily all at once. A transitional period during which both teams continue to operate under a shared governance structure helps prevent the loss of local expertise.
There is a real risk that tariff harmonization could lead to noticeable increases in certain areas
Clear communication and a phased convergence schedule help limit the impact, which nevertheless remains a major concern.

An effective pricing strategy relies on a rigorous segmentation between image products (KVI) and margin drivers to maximize profitability. By balancing perceived value and competitive data, this approach can increase EBITDA by up to 15%. This strategy then translates into a concrete pricing policy that is applied on a daily basis. Clear governance and automated rules ensure consistent execution despite market fluctuations.
Strategic pricing defines long-term positioning to maximize profitability and price image, unlike daily operational adjustments. This framework structures range architecture and governance to prevent gut-feeling decisions. In retail, 62% of buyers prioritize price, making this compass essential for protecting margins against competition.
The success of a pricing project depends not only on the tool, but also on a rigorous methodology that combines data quality with team buy-in. This structured approach allows you to move away from risky manual management and implement automated rules, thereby ensuring long-term profitability and commercial consistency.
