Watermill Group Exits CTB to Waterland in European PE Handoff

In a textbook mid-market private equity transition, Watermill Group announced it has successfully exited its investment in Cooper Turner Beck (CTB), transferring ownership to Waterland Private Equity. The transaction, announced May 13, 2025, marks the culmination of a three-year value creation program that positioned the Germany-based industrial packaging distributor for its next phase of expansion under new stewardship.

While financial terms remain undisclosed—standard practice for mid-market European transactions of this nature—the deal represents a strategic handoff between two sophisticated investors with complementary playbooks. Watermill, known for operational transformation of founder-led businesses, is passing the platform to Waterland, a growth-oriented firm with deep experience scaling industrial distribution platforms across continental Europe.

CTB operates at the intersection of two resilient industrial trends: the ongoing shift toward e-commerce fulfillment and the European Union's aggressive push for sustainable packaging solutions. The company serves as a critical supply chain partner, providing corrugated packaging, protective materials, and technical packaging solutions to manufacturers and distributors across Germany and neighboring markets.

Under Watermill's ownership since 2022, CTB pursued a classic buy-and-build strategy, completing several bolt-on acquisitions to expand geographic reach and service capabilities. The firm invested heavily in digitizing customer interfaces and modernizing warehousing infrastructure—table stakes improvements in an industry where legacy players often operate with outdated systems.

Waterland Private Equity, headquartered in the Netherlands with €15 billion in assets under management, brings a different skill set to the table. The firm specializes in nurturing mid-sized European businesses through international expansion, particularly within fragmented distribution sectors.

For CTB, this likely signals a more aggressive growth phase. Waterland's portfolio includes several industrial distribution businesses that have successfully expanded across borders through a combination of organic growth and strategic M&A. The firm's investment committee has demonstrated patience with multi-year integration projects—a necessity when consolidating family-owned competitors in markets like Germany, where cultural fit and customer relationships matter as much as financial engineering.

This transaction fits squarely within a broader private equity theme: the systematic consolidation of European industrial distribution. These businesses rarely generate headlines but offer compelling investment characteristics—recurring revenue from consumable products, sticky customer relationships, and meaningful fragmentation that rewards scale players.

According to PitchBook, European middle-market PE activity in the industrial sector reached €47 billion across 312 transactions in 2024, with distribution businesses representing approximately 18% of deal volume. The packaging subsector specifically has attracted sustained interest, driven by e-commerce tailwinds and regulatory mandates around recyclable materials.

Watermill's three-year hold period sits at the shorter end of the spectrum for industrial platform investments, suggesting either exceptional execution or favorable market conditions—possibly both. The firm likely benefited from multiple expansion in the industrial sector, where public market comps have recovered substantially since the 2022-2023 valuation correction.

Several factors typically drive sub-five-year exits in this playbook:

Strategic buyer interest at premium valuations — While Waterland is a financial buyer, the competitive process may have included strategic acquirers willing to pay for synergies.

Fund lifecycle pressures — Watermill's fund vintage may have entered its harvest period, creating natural pressure to monetize performing assets.

Stage-appropriate transition — The business may have reached the limits of Watermill's value-add capabilities, making a handoff to a growth specialist logical.

One critical detail absent from the announcement: the status of CTB's management team. In secondary buyouts like this, management rollover equity is standard—executives who performed well under the first sponsor typically receive meaningful stakes in the new structure, aligning incentives for the next leg of value creation.

This continuity matters enormously in distribution businesses where relationships with both suppliers and customers depend on personal trust. Waterland's track record suggests they prize operational continuity, often structuring deals that reward existing management for hitting ambitious growth targets.

This deal closes during a transitional period for European private equity. After a challenging 2023 marked by valuation disconnects and limited exit activity, 2024 saw a modest recovery in transaction volumes. According to Preqin, secondary buyouts accounted for 38% of European PE exits in 2024, up from 31% the prior year—a reflection of strategic buyers remaining cautious while financial sponsors found ways to transact with each other.

The Watermill-to-Waterland transition illustrates why sponsor-to-sponsor deals have gained favor: both parties understand the asset class intimately, diligence moves faster, and valuation methodologies align more naturally than in strategic negotiations where synergy assumptions create friction.

Based on Waterland's historical playbook with similar assets, CTB will likely pursue several parallel workstreams:

Geographic expansion beyond Germany — Targeting adjacent markets like Austria, Switzerland, and potentially Benelux countries where packaging distribution remains fragmented.

Product line extensions — Moving upstream into custom packaging design or downstream into fulfillment services, capturing more wallet share from existing customers.

Accelerated M&A — With Waterland's backing, CTB likely has significantly more capital available for acquisitions, potentially targeting €10-50 million revenue businesses that would have been too large under Watermill's ownership.

Digital platform investments — Further modernizing e-commerce capabilities and supply chain visibility tools that differentiate CTB from traditional competitors still relying on phone and fax orders.

One underappreciated driver in packaging distribution deals: European regulatory tailwinds. The EU's Packaging and Packaging Waste Directive mandates increasingly stringent recyclability targets, creating competitive advantages for distributors who can source and certify compliant materials. CTB's ability to navigate these requirements likely factored into Waterland's investment thesis—companies that solve regulatory headaches command premium pricing.

While the press release does not detail advisory teams, transactions of this profile typically involve sell-side M&A advisors, accounting firms handling quality of earnings analysis, and legal counsel managing cross-border structuring complexities. For a business of CTB's scale (likely €50-200 million in revenue based on typical Watermill platform sizing), the advisory ecosystem would include mid-tier investment banks with industrial sector expertise rather than bulge-bracket firms.

The absence of debt financing details suggests Waterland used a combination of fund equity and moderate leverage—standard for industrial distribution plays where cash flow stability supports borrowing but working capital swings require financial flexibility.

This deal exemplifies why industrial distribution has become a private equity staple. These businesses offer:

Predictable cash generation — Consumable products create natural replenishment cycles

Fragmentation opportunities — Thousands of family-owned competitors ripe for consolidation

Operational improvement levers — Digitization, procurement optimization, and route density gains

Multiple expansion potential — Public market comps trade at higher multiples than private acquisitions, creating built-in arbitrage

Yet these businesses also demand patience. Cultural integration challenges, customer concentration risks, and supplier relationship management require sophistication that goes beyond financial engineering. The Watermill-to-Waterland transition suggests both firms recognize these complexities and have structured their respective strategies accordingly.

The sale of CTB represents private equity operating as designed—a systematic progression from operational foundation-building under one sponsor to growth acceleration under another. For Watermill, it validates the thesis that founder-led industrial businesses can be professionalized and positioned for premium exits in relatively compressed timeframes. For Waterland, it provides a platform with proven management and embedded infrastructure, ready for the next phase of value creation.

As European PE markets continue normalizing after the disruptions of recent years, expect more deals like this: pragmatic, strategy-driven transitions between sophisticated buyers who understand that not every investment needs to swing for the fences. Sometimes the most successful exits are the ones that simply set up the next owner for success.

The industrial distribution consolidation story is far from over—CTB's journey simply moved from chapter one to chapter two. Those tracking European mid-market PE would be wise to watch how Waterland deploys capital behind this platform over the next 24 months. The real test of both sponsors' strategies plays out not in the press release, but in the operational execution that follows.
