At a glance: Buy-and-Build describes a growth strategy in which a company (the platform) is scaled into a significantly larger provider through a series of targeted acquisitions (add-ons). In the German Mittelstand, this model has become one of the dominant consolidation forces. In 2024, 66.7 percent of all European private equity buyouts were already add-on acquisitions — rising to 71.4 percent in Q1 2026. For mid-market entrepreneurs, this means two things: those who want to acquire will find favorable valuation spreads and a large pool of potential targets; those who want to sell gain access to professional buyers who strategically acquire companies with as little as one million euros in EBITDA.
What Buy-and-Build Actually Means
A Buy-and-Build strategy combines two building blocks. It begins with a platform company that has a sufficiently stable operational and financial foundation to integrate further businesses. On top of this platform, the investor or owner then executes a series of so-called add-on acquisitions — smaller businesses that are incorporated into the platform to expand geographies, complete product portfolios, secure talent, or gain regional market share.
Professor Bernhard Schwetzler of HHL Leipzig describes the concept in the Palgrave Encyclopedia of Private Equity 2024:
"In this strategy, a private equity fund acquires a platform company and then sequentially acquires further companies, so-called add-ons, to bolt them on to the platform."
The economic logic is straightforward. Platforms are typically valued at higher multiples than add-ons. In the DACH Mittelstand, the valuation gap between a company with EUR 2 million EBITDA and one with EUR 15 million EBITDA is two to five EBITDA multiples. Anyone who manages to consolidate several small units under one roof automatically elevates the valuation multiple of the overall group — an effect the literature calls multiple arbitrage.
Buy-and-Build, Roll-Up, or Classic Buyout?
The three terms are often used interchangeably but describe different things. A roll-up is the aggressive American variant, in which a large number of similar small providers are acquired in a short period and standardized. Buy-and-Build is the more strategic evolution — integration takes center stage, not just aggregation. A classic buyout refers to a single acquisition without sequential follow-on acquisitions.
| Model | Number of Acquisitions | Integration Depth | Typical Investor |
|---|---|---|---|
| Classic Buyout | 1 | High or low | PE or strategic buyer |
| Roll-Up | 10 or more | Medium, focused on cost synergies | Specialized consolidators |
| Buy-and-Build | 3 to 20+ | High, including revenue synergies | PE or strategic platform |
Why Buy-and-Build Shapes the German Mittelstand
Three developments are converging right now, making Buy-and-Build the dominant value-creation strategy in the DACH region.
First, the succession wave. KfW's 2025 Succession Monitoring documents that 545,000 mid-market businesses are seeking succession solutions by end of 2029 — around 109,000 transitions per year. At the same time, 57 percent of German Mittelstand owners are already 55 or older. This structural selling pressure creates a permanent pool of acquisition-ready companies that is likely to persist for at least a decade.
Second, market fragmentation. Industries such as HVAC, IT services, dental and veterinary medicine, fiber-optic construction, industrial services, and marketing agencies are extremely fragmented in the DACH region. In HVAC alone, around 36,300 businesses generate combined revenues of EUR 50.1 billion. Such structures are ideal consolidation fields.
Third, investor capital pressure. European private equity funds held approximately EUR 434.8 billion in uninvested capital (dry powder) in 2025. This money must be deployed within fund lifetimes. Simultaneously, multiple expansion through pure market appreciation has become harder since the 2022 rate hike cycle. Operational value creation through consolidation is now the primary return lever.
The PwC Private Equity Trend Report 2026 reports that 62 percent of European PE managers cite Buy-and-Build as one of their two most important strategies for the coming years. According to the DBAG/FINANCE Midmarket Monitor, 81 percent of DACH investors view Buy-and-Build as their preferred value creation method — making it standard practice, not a niche approach.
Multiple Arbitrage: The Central Value Driver Explained
Multiple arbitrage sounds complex, but at its core it is a simple arithmetic operation. It works because the market for small businesses is less efficient than the market for large ones. A company with EUR 1 million EBITDA is typically valued at four to six times EBITDA in the DACH Mittelstand. A company with EUR 10 million EBITDA in the same sector readily commands eight to nine times. Consolidating five add-ons moves your position up the valuation table.
A Mid-Market Example
Imagine a platform company in technical services. EBITDA: EUR 3 million. Entry multiple: seven times. The investor pays EUR 21 million enterprise value.
Over three years, the company acquires four add-ons — each with around EUR 1 million EBITDA, each at a five-times multiple. Four times EUR 5 million equals EUR 20 million invested for EUR 4 million additional EBITDA.
Post-integration, consolidated EBITDA stands at EUR 7 million. Add estimated 15 percent synergies on the add-on side — another EUR 600,000 — giving EUR 7.6 million EBITDA. Total investment: EUR 41 million. Weighted entry multiple: 5.4x. At exit after five years, the group achieves EUR 10 million EBITDA and is valued as a scaled mid-market platform at nine times — a sale price of EUR 90 million.
Of the EUR 49 million in value creation, approximately EUR 36 million comes from the multiple expansion alone. This explains why the HHL-Lancaster study by Hammer documents a platform premium of 28 percent on average over single buyouts, and why the BCG study "Power of Buy and Build" documents 31.6 percent IRR for Buy-and-Build deals versus 23.1 percent for stand-alone investments.
The Seller's Perspective: When Your Company Becomes the Add-on
For Mittelstand owners 55-plus who are seeking a succession solution, selling to a Buy-and-Build platform is often more attractive than selling to a strategic buyer or a classic PE house. Boris Dürr, partner at Heuking law firm, puts it this way:
"When implementing Buy-and-Build concepts, the minimum revenue or profit requirements that normally apply to financial investors are not applicable, or are significantly lower."
Classic PE houses typically only buy from around EUR 10 million EBITDA. Buy-and-Build platforms are interested in businesses from EUR 500,000 to EUR 2 million EBITDA if the strategic logic fits — opening smaller mid-market businesses to professional sale processes and institutional valuation levels.
What You Gain as a Seller
The first advantage is liquidity: a structured sale brings capital into your private assets today that you would otherwise have to extract over years in profit distributions. The second is the synergy premium — platforms can quantify the value your business creates within the group and are willing to price part of that premium into the purchase price.
The third advantage is the roll-over option: re-investing part of the sale proceeds into the platform lets you participate in its further value growth. This "second bite of the apple" logic can significantly increase total exit proceeds because the platform exit after three to five years typically occurs at materially higher multiples.
The fourth advantage is a genuine succession solution. A platform takes over not just your equity but integrates your employees into a larger structure, often secures the location contractually, and gradually assumes operational responsibility. For many owners without a family successor, this is a more humane solution than closure.
What You Must Scrutinize
Before signing a letter of intent, every seller's checklist should include these points:
- Investor track record. How many platforms has the house built? How did the exits go? Speak to other add-on sellers from the same platform — reference calls are standard in the industry.
- Integration plan. Get a concrete picture of how your company will be integrated in the first 100 days. Which functions are centralized? Which stay at your location?
- Brand and location commitments. If your brand and regional presence matter, ensure corresponding commitments appear in writing in the purchase agreement.
- Roll-over valuation mechanics. At what multiple is your reinvestment valued? Are there liquidation preferences favoring the lead investor?
- Earn-out protection. If part of the purchase price is tied to future EBITDA targets, you need protective clauses against manipulation of the reference metric by the buyer.
The synergy premium is not automatic — it is negotiated. Selling without competitive tension and without professional advisors almost certainly leaves money on the table.
The Buyer's Perspective: When Your Company Becomes the Platform
If you currently run a mid-market business and are weighing whether to acquire rather than sell, the question of platform readiness is central.
Platform Prerequisites
A weak platform cannot be repaired through add-ons — every acquisition amplifies structural weaknesses. Many PE houses have paid dearly for this lesson. Before seriously pursuing a Buy-and-Build strategy, your company should meet these prerequisites:
- Clean monthly reporting structures with cost-center accounting and a balance sheet accessible to external investors
- A second management tier that operates independently of the owner
- An ERP system that can accommodate additional sites without each acquisition becoming a standalone IT island
- A market position that represents a clear USP relative to potential add-ons
- Sufficient working capital discipline with cash conversion above 70 percent
- A clear target picture for the group's end state in five years
Christian Futterlieb of VR Equitypartner frames this last point decisively:
"The most important thing is a clear target vision. What should the business model and organization look like after the Buy-and-Build strategy has been executed in roughly five years, and what steps do we need to take to get there?"
Without this vision, buyers fall into the collector trap: three add-ons later, there are three ERP systems, three payroll departments, three brand identities, and no real synergy realized.
Financing the Strategy
In today's rate environment (2025–2026), the financing landscape has shifted significantly. Where 25–40 percent equity once sufficed, German commercial banks now require 40–55 percent. Senior debt pricing is EURIBOR plus 250 to 425 basis points. Unitranche financing from debt funds is available but costs 9–11 percent all-in.
In practice, most mid-market platform builders use blended financing: 35–45 percent equity, supplemented by bank senior debt, a vendor loan from the selling entrepreneur, and in some cases an earn-out. Vendor loans are subordinated to bank debt and carry 6–10 percent interest.
Those who want to scale faster will bring in a private equity partner — who contributes not just capital but a network of potential targets, a 100-day plan, operating partners with sector experience, and access to institutional financing.
From First Meeting to Closing: The Typical Process
A Buy-and-Build process typically takes three to nine months depending on complexity. These phases occur in virtually every transaction:
Phase 1: Preparation and Vendor Due Diligence (4–8 weeks) Preparation of financial metrics with documented EBITDA bridging, data room setup, and information memorandum. Clean EBITDA adjustments can lift value by 20–50 percent.
Phase 2: Buyer Outreach and Selection (4–6 weeks) Structured process with long list, short list, and a controlled competitive situation. Competitive tension typically lifts sale price by 15–30 percent versus bilateral negotiation.
Phase 3: Indicative Offers and Management Presentations (4–6 weeks) Serious bidders submit non-binding offers. The top two or three are invited to management meetings where seller and potential buyer get to know each other personally.
Phase 4: Due Diligence and Final Negotiation (6–8 weeks) The selected buyer conducts legal, tax, financial, and operational due diligence. The key terms of the purchase agreement are negotiated in parallel.
Phase 5: Signing and Closing (4–6 weeks) Contract execution and completion of the transaction. Closing conditions such as antitrust clearances and financing drawdowns are typically resolved in the weeks between signing and closing.
Vendor Loans, Earn-Outs, Roll-Overs: The Key Deal Structures
Purchase prices in Buy-and-Build deals are rarely paid entirely in cash. These structures are standard in the mid-market segment:
Vendor loan. 10–25 percent of the purchase price remains as a subordinated loan with the seller. Typical interest: 6–10 percent per year, term three to seven years. Benefit for buyer: less bank financing needed. Benefit for seller: interest well above current bond yields. Risk: subordination to bank debt — in insolvency, there is a risk of total loss.
Earn-out. A portion of the purchase price is tied to achieving specific EBITDA or revenue targets over the next two to three years. Portions of 15–25 percent of total purchase price are common in the mid-market. Earn-outs can be a fair instrument to bridge valuation gaps but are conflict-prone. Protective clauses — such as caps on central cost allocations or acceleration upon ownership change — are essential.
Roll-over (Rückbeteiligung). The seller reinvests part of the proceeds into the buyer consortium, often at the platform level. Typical amounts: 5–25 percent of sale proceeds. The reinvestment can be structured tax-neutrally under Section 21 of the German Reorganization Tax Act. Benefit: participation in the platform exit at higher multiples after three to five years. Risk: entrepreneurial capital — if the platform fails, the money is gone.
Which Industries Are Best Suited
Not every industry lends itself equally to a Buy-and-Build strategy. Three characteristics must converge: market fragmentation, quantifiable synergies, and a structural demand driver. Currently most active in the DACH region:
- HVAC (heating, ventilation, air conditioning) — Builtech grew from a handful of locations to over 50 integrated businesses in seven years, selling to the Dutch VDK Groep in 2025 for several hundred million euros.
- Veterinary medicine and dental MVZ. IVC Evidensia, AniCura, and zahneins have fundamentally reshaped the animal and dental practice market over the past decade.
- IT services and systems integrators. Cancom, Highberg, and citadelle are consolidating a market with over 2,000 mid-market providers.
- Fiber and energy infrastructure construction. Vitronet grew under DBAG backing from EUR 42 million pro-forma revenue to over EUR 500 million with around 2,700 employees.
- B2B SaaS and vertical software. Solvares consolidates field service optimization with 73 percent recurring revenues.
- Industrial services and specialty construction. The TERRAS Group grew its EBITDA from around EUR 4 million to EUR 27 million in a few years.
Less suited: high owner-dependency businesses like gastronomy and education, pure contract manufacturing with thin margins, and project businesses that rely heavily on the owner's personal relationships.
Frequently Asked Questions About Buy-and-Build in the Mittelstand
What is Buy-and-Build in simple terms?
Buy-and-Build is a growth strategy in which a platform company is built into a significantly larger provider through a series of targeted add-on acquisitions. The goal is to gain market share, capture synergies, and achieve a higher enterprise value through multiple arbitrage.
What is the difference between a platform company and an add-on?
The platform company is the initial, larger acquisition that serves as the operational foundation. It requires professional reporting structures, a second management tier, and scalable IT. Add-ons are smaller follow-on acquisitions integrated into the platform to extend geography, product portfolio, or customer access. Platforms are valued at higher multiples than add-ons.
What multiples do Buy-and-Build investors typically pay?
In the DACH Mittelstand, platform multiples for EUR 5–10 million EBITDA industrial businesses are typically 6x to 8.5x EBITDA. Software and IT services platforms achieve 9x to 13x. Add-ons under EUR 2 million EBITDA are generally valued at 3.5x to 5.5x; add-ons between EUR 2–5 million EBITDA at 5x to 7x. Spreads between platform and add-on multiples typically range from two to five EBITDA turns.
Is selling to a Buy-and-Build platform worthwhile for a business with EUR 5 million revenue?
Yes, in most cases. Buy-and-Build platforms are interested in businesses from EUR 500,000 EBITDA upward if the strategic logic fits. Compared to selling to a local competitor or a single buyer, a structured process gives you access to multiple professional buyers and therefore better negotiating leverage.
What is multiple arbitrage?
Multiple arbitrage describes the effect that small companies trade at lower valuation multiples than large ones. Consolidating several small units into a larger group automatically elevates the overall group's multiple. At exit, the consolidated group is valued at a higher multiple than the weighted average of the individual acquisitions.
Which industries are most suitable for Buy-and-Build?
Highly fragmented markets with recurring revenues, clear back-office scale effects, and structural demand drivers. Currently active: HVAC, IT services, dental and veterinary medicine, fiber construction, B2B software, and industrial services. Less suitable: high owner-dependency services, pure contract manufacturing, and project-based businesses.
What happens to my employees after selling to a Buy-and-Build platform?
Employees transfer automatically to the acquirer under Section 613a of the German Civil Code. The platform integrates staff into its structures, typically centralizing back-office functions such as accounting, IT, and HR over 12–24 months. Key employees often receive retention bonuses of 25–100 percent of annual salary. Operational staff and the location are typically preserved, as that is where the value creation occurs.
Will I still be involved in the business after the sale?
That depends on the arrangement. Classic transition periods run six to 24 months. If you hold a roll-over stake, longer operational involvement is often desired but not mandatory. Sellers who are exiting for retirement can negotiate a significantly shorter handover period.
What are the advantages of selling to a Buy-and-Build platform versus a strategic buyer?
Buy-and-Build platforms are often more structured and faster in the process than strategic buyers because they acquire regularly. They frequently pay a synergy premium because they can quantify the specific value your business adds within the group. Strategic buyers typically see only their own synergy circle and rarely share that value with the seller in the pricing.
What are the risks of Buy-and-Build for the seller?
Key risks include: loss of entrepreneurial independence, potential brand or location changes post-integration, earn-out risks if targets are missed, credit risk on the vendor loan, and rollover risk if the platform fails. Contractual protection of these risks is essential.
How long does a Buy-and-Build process take from first contact to closing?
Typically three to nine months in the mid-market, depending on complexity. Preparation and vendor due diligence: four to eight weeks; buyer outreach and selection: four to six weeks; indicative offers and management presentations: four to six weeks; due diligence and final negotiation: six to eight weeks; signing to closing: four to six weeks.
What is a roll-over and how large is it typically?
In a roll-over (Rückbeteiligung), the seller reinvests part of the sale proceeds into the new buyer consortium, often at the platform level. Typical amounts: 5–25 percent of sale proceeds. The reinvestment can be structured tax-neutrally under German reorganization tax law. You thereby participate in the later platform exit, which typically occurs at significantly higher multiples after three to five years.
What does an M&A advisor cost for a Buy-and-Build transaction?
Market standard in the mid-market segment: monthly retainers of EUR 3,000–10,000 plus a success fee of 3–7 percent of transaction volume, with a minimum fee of EUR 100,000–150,000. The success fee typically finances itself from the additional proceeds that a professionally structured process achieves over a bilateral sale.
How is my company valued for a Buy-and-Build transaction?
The standard methods are the EBITDA multiple approach and the discounted cash flow method. The multiple approach dominates in the Mittelstand. The calculation starts with normalized EBITDA for the last twelve months, multiplied by the industry-specific multiple. Key value drivers include: earnings stability, growth, market position, owner-independence, customer concentration, recurring revenues, and synergy potential with the buyer.
What happens to my company after the platform is sold?
If you hold a roll-over stake, you receive your share of the proceeds when the platform is sold. The platform is typically sold to a larger PE investor, a strategic buyer, or via an IPO. Your former operating unit generally remains part of the sold group.
Conclusion: When Buy-and-Build Is the Right Solution
Buy-and-Build is no longer a niche strategy — it is standard practice in the DACH Mittelstand. For entrepreneurs thinking about the future of their life's work, the strategy opens two paths.
The first path leads to the platform. Those who run a professionally structured business with a second management tier and clean reporting can become consolidators themselves — with or without a PE partner, depending on ambition and capital needs.
The second path leads to becoming an add-on. For most mid-market entrepreneurs in the EUR 500,000 to EUR 5 million EBITDA range, this is the more realistic and often more attractive path. Buy-and-Build platforms are structured buyers who run professional processes, pay fair valuations, and enable proceeds through synergy premiums and roll-over models that a local buyer rarely matches.
In both cases, preparation quality is decisive. Those who acquire without a strategy fail. Those who sell without professional preparation leave money on the table.
