The lower mid-market — also known in Spain as the mid-small market — is the most active and dynamic segment of Spanish M&A. Made up of companies with revenue between €3 million and €40 million, it accounts for most SME sale deals, draws growing interest from private equity funds, search funds, and strategic buyers, and is the true engine of Spain's business landscape.
In this guide, we explain exactly what the lower mid-market is, which ranges define the segment, what data exists on the market in Spain, which types of investors are most active, what makes these deals distinctive, and why this segment holds so much potential for business owners and investors.
What the lower mid-market is
The lower mid-market is the M&A segment that groups together small-to-midsize companies in terms of revenue, EBITDA, and deal value. It sits above the small market (micro-businesses) and below the core mid-market (companies with revenue above €50M).
In Spain, the lower mid-market is especially relevant because it contains the bulk of the productive business base: family businesses, founder-led companies, or companies with majority shareholders, with established revenue, professional teams, and proven business models.
Ranges that define the lower mid-market in Spain
At Deale, we define the lower mid-market by combining several criteria, since no single parameter fully captures the profile of these companies:
- Annual revenue: between €3M and €40M
- EBITDA: between €0.5M and €5M
- Deal value (enterprise value): between €5M and €50M
- Number of employees: between 20 and 250 employees
- Typical profile: family businesses, founder-led companies, or companies with majority shareholders
This definition reflects how the segment actually works: companies large enough to attract professional investors (strategic buyers, family offices, private equity funds), but below the threshold where the large international funds of the upper mid-market come in.
Why the lower mid-market is the most active segment of Spanish M&A
Although large deals grab the headlines, the lower mid-market is where real M&A activity in Spain is concentrated. There are five structural reasons behind the segment's dynamism, backed by recent market data:
1. Spain's business landscape is lower mid-market by nature
Spain has one of the most fragmented economies in Europe: 99% of its businesses are SMEs, and a very high percentage of them generate between €3M and €40M in revenue. The lower mid-market isn't a minor niche: it's the backbone of the country's productive economy.
2. Business succession is the segment's engine
Generational succession is driving a surge in activity. According to data from deals managed on Deale in the first quarter of 2026, 90% of sales in this segment are driven by the lack of a successor or the founder's retirement. In recent surveys, one in two companies in the segment explicitly cites the absence of a successor as the main trigger for the process, and 25.5% mention retirement.
3. Buyers want to close, but they're more demanding
Investor interest is real and growing: 81.2% of investors say they expect to close deals in 2026, according to Deale data reported in El Economista. However, the market is maturing: 75% admit that opportunities “sometimes fit and sometimes don't,” and 50% consider the information they receive on companies of this size insufficient. Buyers in the lower mid-market are more demanding and more professional than they were a few years ago.
4. Sectors with structural momentum
The segment's growth is concentrated in sectors with solid underlying logic, not passing trends. Industry and construction, software and IT services, transportation and logistics, energy and renewables, and primary-sector activities are where the most deals close. What they have in common: specialization, export capacity, or structural demand.
5. A less competitive market than the upper mid-market
Large deals in the upper mid-market and large cap space attract international funds with deep pockets, which drives multiples up. The lower mid-market has less institutional competition, allowing local investors (search funds, family offices, domestic PE firms, strategic buyers) to find opportunities at more reasonable multiples and build portfolios with discipline.
The lower mid-market in data: the market by the numbers
Understanding the real size of the lower mid-market in Spain is key to seeing why it's the most active M&A segment. The following data comes from the BORME (Boletín Oficial del Registro Mercantil, Spain's Official Gazette of the Commercial Registry) and reflects all deals closed in the Spanish market
Market volume in Spain
In 2025, 1,945 lower mid-market deals closed in Spain, representing +21% growth over 2024 (1,604 deals). The segment's aggregate volume reached €9,456 million.
Geographic distribution
Activity is concentrated in Madrid and Catalonia, which together account for more than 50% of deals in the market. Here is the data by autonomous community (deals closed in 2025):

Deale's perspective within the segment
As a specialized platform, Deale has grown in step with the market and faster than it. In the first quarter of 2026, we facilitated the closing of 10 deals worth more than €41 million, representing 4% of lower mid-market deals in Spain during the period. In a quarter when the overall market shrank by 17%, Deale increased its activity fivefold (+400%) compared with Q1 2025 (from 2 to 10 closed deals).
The deals closed this quarter have a profile typical of the lower mid-market:
- Average revenue: €8.6M
- Average EBITDA: €814,000
- Average time to close: 120 days
- Buyer type: strategic buyers and family offices accounted for nearly 60% of demand
- Repeat buyers: 20% of buyers had previously done deals with Deale
- Sector diversity: consulting, education, advanced manufacturing, dentistry, IT services, facade renovation, industrial coatings
These figures confirm the consolidation of Deale's digital model in the segment's sale processes. Beyond closed deals, the platform has 23,000 registered users — 10,380 investors, 9,500 SMEs in the process of selling, and 3,000 advisors — and receives around 250 business sale proposals every week.
The Spanish mid-market as a strategic ecosystem
In today's environment, what matters in the lower mid-market goes beyond the data: it's about market dynamics, expectations, and the evolution of buyer behavior.
🗞️ On April 28, 2026, Gerard García, founder and CEO of Deale, published an op-ed in El Economista (Capital Privado) titled “Who Buys in the Spanish Mid-Market and What Does It Take to Close Deals Today?”, in which he analyzes this evolution:
“For decades, the Spanish mid-market was a segment with little visibility. While the media and financial spotlight focused on large listed companies or high-growth startups, many established SMEs stayed off the radar. Today, the landscape is changing.”
Garcia identifies a profound shift in the buyer profile: it's no longer just large private equity funds that operate in this space. Family offices, strategic corporates, and local management teams are looking with growing interest at companies with solid models, stable customer bases, and room to grow.
“These aren't companies ‘still to be proven,’ but profitable SMEs with a track record, accumulated know-how, and structures that, with the right support, can take a leap in scale.”
The op-ed also identifies the segment's main source of friction: trust. Rather than a lack of buyer appetite, many deals stall because of disagreements over valuation, unrealistic expectations, complex structures, or information that isn't good enough to make decisions quickly.
García concludes with an idea that sums up the segment's opportunity:
“The Spanish mid-market isn't a secondary space, but an ecosystem full of strategic opportunities. But for that potential to materialize, the market must move toward a more professional standard, with less information asymmetry, more signals of reliability, and better alignment between what's being sold and what buyers are actually looking for.”
Who buys in the lower mid-market
One of the defining features of the lower mid-market is the diversity of buyer profiles. Unlike large cap (dominated by mega funds) or the small market (where individual investors prevail), this segment brings together five very different types of buyers, each with its own investment thesis and criteria:
1. Strategic buyers
Companies in the same or complementary sectors that acquire in order to integrate and create synergies. They pay the highest multiples in the segment because they can monetize operational, commercial, or industrial synergies that justify the premium.
What they look for: companies with complementary customers, new geographic coverage, technical or production capabilities, and key talent.
2. Family offices
Investment vehicles of business-owning families with a long investment horizon (10+ years). They pay high multiples because they can afford more patient returns and aim for permanent ownership, not an exit.
What they look for: companies with stable cash flow, an established competitive position, sectors resilient to economic cycles, and professional teams that stay on after the deal.
3. Private equity funds
Professional vehicles that combine capital from institutional investors with bank leverage. They apply strict financial criteria and work with 5–7-year horizons. In the lower mid-market, domestic and regional funds dominate, while large international funds focus on bigger deals.
What they look for: companies with clear growth potential, room to improve operating margins, and the opportunity to execute buy-and-build strategies (sector consolidation).
4. Search funds
Entrepreneurs who seek to acquire a company to run it themselves, usually backed by investors who fund their search. They apply the most conservative multiples in the segment because they finance the purchase with leverage and need structures where the business's cash flow comfortably covers the debt.
What they look for: stable companies with recurring EBITDA, healthy margins, and a management team that allows for an orderly transition.
5. Individual investors
Professionals with executive experience or entrepreneurs who acquire companies as a personal investment, often intending to manage them actively. They apply mid-range multiples and are usually more limited in size than the other profiles.
What they look for: smaller companies within the lower mid-market, with potential for operational improvement, in sectors they know or can master quickly.
Each profile applies different EBITDA multiples depending on its investment thesis and financial structure. If you want to dig deeper into how these multiples are built, check out our complete guide to EBITDA multiples.
