The segment of companies with annual revenues typically between 5 and 100 million euros, representing the largest pool of M&A opportunities and the core of most economies.
The middle market is the largest, most dynamic, and most under-served segment of the M&A landscape. It sits between the small businesses that are too tiny for institutional investors and the large corporations that dominate headlines. It is where the real economy lives — and where the best risk-adjusted returns in private investment are often found.
The middle market (also called mid-market) refers to companies whose annual revenues fall roughly between 5 million and 100 million euros. This is not a legally defined segment; the boundaries vary by country, source, and context. In Spain, Blue Mountain defines its target mid-market as companies with revenues of 3 to 50 million euros, though we consider opportunities outside this range when the fundamentals are compelling.
Within the broader mid-market, practitioners often distinguish:
The middle market’s significance to the economy cannot be overstated. In Spain, mid-market companies collectively account for the majority of private-sector employment and a substantial share of GDP. They are the industrial fabric of the country — the manufacturers, service providers, distributors, and operators that make the economy function.
Several structural characteristics make the mid-market a compelling investment segment:
Pricing efficiency. Large-cap transactions attract intense competition from global PE funds, driving valuations to levels that leave little margin for error. In the mid-market, competition is thinner because many institutional investors have minimum ticket sizes that exclude these deals. This means buyers can often acquire companies at more reasonable multiples — typically 5x to 7x EBITDA compared to 8x to 12x in the large-cap market.
Operational improvement potential. Mid-market companies frequently have significant room for improvement in areas such as governance, financial reporting, digitalisation, commercial strategy, and procurement. An investor who can professionalise these areas creates tangible value that translates directly into higher EBITDA and higher exit multiples.
Fragmented sectors. Many mid-market companies operate in sectors that are ripe for consolidation. By acquiring a platform company and then adding smaller bolt-on acquisitions, an investor can build a larger, more efficient business worth a higher multiple than its individual parts — the classic “buy and build” strategy.
Resilience. Mid-market companies tend to be deeply embedded in their local economies and sectors. They have long-standing customer relationships, specialised expertise, and a level of operational flexibility that larger companies lack. This makes them surprisingly resilient through economic cycles.
Succession-driven supply. The demographic wave of baby-boomer founders reaching retirement age is creating a steady supply of high-quality mid-market companies coming to market. These are not distressed assets; they are well-run businesses whose owners are ready for the next chapter.
Spain’s mid-market has several distinctive features that make it particularly interesting for investors:
The economy is heavily services-oriented but retains a significant industrial and manufacturing base, particularly in regions such as Catalonia, the Basque Country, Valencia, and Murcia. Many mid-market companies in these regions are global leaders in their niches — a packaging company supplying the European cosmetics industry, an engineering firm servicing international energy infrastructure, a food producer exporting to thirty countries.
The M&A market has matured considerably. According to industry data, Spain consistently ranks among the top five European markets by volume of mid-market transactions. The advisory ecosystem has grown accordingly, with a healthy mix of domestic and international firms serving this segment.
Yet the market remains less competitive than the UK, France, or Germany for mid-market deals. Fewer institutional investors focus on the Spanish lower mid-market, which creates opportunities for family offices and specialised investors like Blue Mountain who have local knowledge, relationships, and the ability to operate in a bilingual (Spanish/regional languages) environment.
As of recent market data, typical multiples in the Spanish mid-market range from 5x to 8x EBITDA for most sectors. Technology, healthcare, and businesses with strong recurring revenue can command 8x to 10x or higher. Cyclical sectors, commodity-dependent businesses, and companies with high customer concentration tend to trade at the lower end. The specific multiple depends on growth prospects, margins, customer diversification, and the competitive tension in the sale process.
No, although family businesses represent the majority. The mid-market also includes corporate carve-outs (divisions sold by larger groups), founder-led startups that have reached scale, management-owned companies, and businesses emerging from restructuring. However, the family business component is the dominant driver of deal flow in the Spanish mid-market.
The key differences are time horizon and capital structure. We invest with patient capital — no fixed fund life, no pressure to exit within a defined period. We typically use moderate or no leverage, reducing financial risk for the acquired company. We seek to be partners, not just financial engineers. And we focus exclusively on Spain, which gives us a depth of knowledge and relationships that generalist international investors cannot easily replicate.
