Who controls IMA Klessmann GmbH and how does that ownership shape strategy?
IMA Klessmann GmbH is now part of a privately held global group after earlier family and corporate phases; this matters because current owners prioritize industrial automation investments. In 2025 the group reported focused capital deployment into digital lines and M&A.

Current owners signal long-horizon investment, so R&D and automation take priority over dividends; ownership stability supports expansion into higher-margin sectors. See detailed product focus in IMA Klessmann GmbH SWOT Analysis.
Who Really Stands Behind IMA Klessmann GmbH?
IMA Klessmann GmbH ownership is concentrated and private: today the business operates as IMA Schelling Deutschland GmbH within the privately held IMA Schelling Group, with control exercised by a concentrated group of private investors led by the Lehner family. Ownership is family-influenced and not publicly traded, so governance is long-term and privately governed.
The Lehner family-notably Maximilian Lehner and Guenther Lehner-holds the dominant stake, increasing to 56.6% as of late 2023, giving them effective control over IMA Schelling Deutschland GmbH.
Remaining equity is held by a concentrated mix of private investors and legacy stakeholders tied to the IMA Schelling Group; founder-line management influence has reduced compared with the original IMA Klessmann GmbH setup.
IMA Klessmann GmbH now functions as IMA Schelling Deutschland GmbH, a privately held, subsidiary-style arrangement inside the IMA Schelling Group rather than a standalone, publicly traded firm.
With the Lehner family at 56.6% and remaining shares with a few private holders, ownership is concentrated, not broadly distributed among institutional investors.
Founder-led identity has waned; insiders and family owners now drive strategic decisions. Management retains operational control but ultimate voting power rests with majority family shareholders.
The clearest picture: IMA Klessmann GmbH (as IMA Schelling Deutschland GmbH) is privately held, majority-controlled by the Lehner family, and operated within the larger IMA Schelling Group, favoring long-term planning over public-market reporting cycles.
Ownership of IMA Klessmann GmbH is private and concentrated: the Lehner family holds majority control through the IMA Schelling Group, supported by a small set of private investors and legacy stakeholders-this defines governance and strategy.
- Lehner family (Maximilian and Guenther Lehner) - main current owner with 56.6% stake
- Private investor group and legacy stakeholders - secondary holders within IMA Schelling Group
- Ownership is concentrated, not broadly dispersed or institutionally held
- Structure is defined by private, family-controlled governance inside the IMA Schelling Group

How Did Ownership Change Along the Way at IMA Klessmann GmbH?
IMA Klessmann GmbH ownership shifted from a family-led Mittelstand firm (1951) through corporate consolidation into HOMAG Group AG (1999), then private equity under Adcuram (2005), and finally strategic industrial ownership by Schelling Anlagenbau GmbH forming IMA Schelling Group (2015-2019), a sequence that reshaped strategy, investment and market position.
| Ownership Event or Period | What Changed | Why It Mattered |
|---|---|---|
| 1951-1999: Klessmann family (Mittelstand) | Founder-led, specialist woodworking machinery; local shareholders and management control | Stable, long-term engineering focus; close supplier and customer ties; limited external capital |
| 1999: Merger into Lignum Technologie AG → HOMAG Group AG | Integrated into a larger corporate group; governance shifted to listed-group structures | Access to scale, broader sales channels, but less autonomy for IMA Klessmann GmbH |
| Nov 2005: Sale to Adcuram Industriekapital AG | Transferred to Munich private equity investor; repositioning for operational improvements and value creation | Infusion of capital and restructuring focus; prepared asset for resale-typical private equity cycle |
| 1 Sep 2015: Acquisition by Schelling Anlagenbau GmbH | Became part of Schelling; formation of IMA Schelling Group | Strategic consolidation in panel processing machinery; increased R&D and cross-selling across parent |
| 2019: Renamed IMA Schelling Deutschland GmbH | Brand and legal alignment under Schelling parent | Unified market presence; clarified ownership for customers, suppliers, and regulators |
The clearest pattern: a move from family ownership to corporate group, then private equity optimization, and finally strategic industrial consolidation under Schelling-each step increased scale or financial discipline and shifted decision rights from local family managers to external investors and then to an industrial parent focused on sector integration.
Ownership evolved from family control to public-group alignment, through private equity, and into strategic industrial ownership-each phase changed investment tempo, governance, and market reach.
- 1951-1999: family-led Mittelstand structure dominated early decisions and shareholder composition
- 1999 merger into HOMAG Group AG was the biggest structural shift toward corporate governance
- 2005 sale to Adcuram materially altered control, introducing private equity timelines and KPIs
- 2015-2019 Schelling acquisition unified ownership and is the enduring strategic parent
Key figures and context: by 2015 transaction records show Schelling's acquisition completed on 1 September 2015; integration culminated in the 2019 rename to IMA Schelling Deutschland GmbH.

Who Really Calls the Shots at IMA Klessmann GmbH?
Real control of IMA Klessmann GmbH rests with the Lehner family through their 56.6% majority stake in IMA Schelling Group, giving them decisive voting power and strategic direction despite executive management by Christoph Geiger and Maximilian Lehner. Control flows from shareholder concentration and board influence rather than diffuse market ownership.
| Person / Group / Entity | Source of Control or Influence | Why It Matters |
| Lehner family | Majority equity holder: 56.6% in IMA Schelling Group; dominant voting bloc | Enables unified strategic decisions, acquisition approvals, and appointment influence over executive and supervisory boards |
| Executive Board (Christoph Geiger, Maximilian Lehner) | Legal management and day-to-day control | Implements strategy set by owners; operationalizes acquisitions and integration |
| Supervisory Board (incl. Wolfgang Rohner) | Long-term partners and industry expertise; oversight role | Aligns operational expertise with ownership goals, reduces agency friction |
Control is concentrated: the Lehner family's 56.6% stake and board representation mean decisions are vertical and fast. Expect major moves-capital allocation, M&A (for example the 2023 purchases of Carmet Automazioni and Blumenbecker Engineering System Technology), and strategic pivots-to be owner-led with limited resistance from minority shareholders, affecting customers, suppliers, and regulatory positioning.
The Lehner family effectively calls the shots through majority ownership and aligned board control, while the executive board runs daily operations. This concentrated governance speeds decisions and prioritizes owner-led strategic moves.
- Majority ownership: Lehner family (56.6%)
- Most influential: Lehner family, supported by supervisory board members like Wolfgang Rohner
- Control: concentrated, owner-driven
- Governance takeaway: streamlined decision-making enables aggressive M&A and clear strategic direction

Why Does IMA Klessmann GmbH's Ownership Matter?
IMA Klessmann GmbH ownership matters because it ties strategic agility to long-term stability: majority control by the Lehner family and integration into IMA Schelling Group align incentives toward patient R&D and industrial leadership, not short-term financial engineering. Ownership affects governance, capital allocation, partner confidence, and the company's ability to fund AI-driven inspection and batch-size-1 automation.
| Ownership Feature | Business Implication | Why It Matters |
| Majority Lehner family control | Stable board, long-term capital allocation | Enables patient R&D spending needed for AI inspection and autonomous material flow |
| Private, family-held within IMA Schelling Group | Governance focused on operational leadership over quarterly returns | Reduces pressure for cyclical cost-cutting; supports Strategy 2030 growth initiatives |
| Group revenue scale: ~€690 million (2023) | Global market footprint with private-firm governance | Offers supplier/customer confidence and resources to fund tech transitions in 2025/2026 |
The clearest takeaway: IMA Klessmann GmbH ownership structure-Lehner family majority within the IMA Schelling Group-creates a capital and governance model optimized for sustained, technology-led growth in 2025/2026 rather than near-term financial exits; partners should expect continuity, heavy R&D commitment, and prioritized industrial innovation.
Majority family ownership aligns leadership incentives with multi-year projects: prioritize AI-driven inspection, autonomous material flow, and batch-size-1 production. Strategy 2030 funding is more likely to be sustained because returns are measured in technological leadership and market share, not quarterly EPS.
Concentration in family hands gives stability and fast decision cycles, but raises insider-control risk if succession or minority protections are weak. Current evidence points to stability supportive of long-term R&D investment rather than imminent divestiture.
Private ownership narrows stakeholder demands, enabling the board to approve capital-intensive, patient projects. Expect governance to favor operational autonomy for the IMA Klessmann management team and centralized strategic oversight from IMA Schelling Group.
For customers, suppliers, and investors in 2025/2026, the ownership profile signals continuity and commitment to product leadership: IMA Klessmann GmbH is positioned as a growth engine, not a sellable asset.
