Who Really Stands Behind Klabin?
Klabin S.A. is founder-led and institutionally backed: the Klabin family controls strategy via Klabin Irmãos S.A. (KA A Participações) with a 19.36 percent stake as of December 30, 2025, while global and domestic institutions hold large positions, making ownership both concentrated in votes and broadly held economically.

Insider and founder stakes

How Did Ownership Change Along the Way at Klabin?
Klabin ownership shifted from a family-run sawmill (1899) to a public company after its 1972 IPO, then to a simplified capital structure and reinforced family control via KA A Participações in 2015; from 2020-2025 foreign institutional stakes grew as investors chased sustainable forest assets and Klabin delivered a 38 percent adjusted EBITDA margin in 2025.
| Ownership Event or Period | What Changed | Why It Mattered |
|---|---|---|
| 1899-1971: Founding and family control | Exclusive family ownership since Maurício Freeman Klabin founded the sawmill | Long-term strategic continuity; family governance norms guided capital allocation |

| 2015 corporate reorganization | Simplified capital structure; family control consolidated under KA A Participações | Clarified voting blocs and strengthened controlling block despite public float |
| 2020-2025: Internationalization | Marked rise in foreign institutional ownership and ESG-focused investors | Higher valuation multiples, deeper free float, and alignment with sustainable-asset demand |

How Ownership Changed Along the Way

Who Really Calls the Shots at Klabin?
Real control at Klabin S.A. rests with voting rights, not cash equity: the founding family, via Klabin Irmãos S.A., holds the dominant voting block and thus practical authority over strategy, board composition, and capital allocation.
| Person / Group / Entity | Source of Control or Influence | Why It Matters |
|---|---|---|
| Klabin Irmãos S.A. | Holds 52.23 percent of common (ON) shares - majority of voting power | Can unilaterally approve strategic pivots, board appointments, and capital plans as of late 2025 |
| Founding family (individual members) | Board representation and concentrated voting control via Klabin Irmãos | Shapes long-term vision, sustainability priorities, and M&A preferences |
| Public/institutional investors | Predominantly hold preferred (PN) shares that provide liquidity but limited votes | Market disciplines share price and liquidity; limited direct control over governance |
| Minority shareholders | B3 Level 2 governance with 100 percent tag-along rights | Protects exit value on control change but does not curb family-led strategic decisions |
Control is highly concentrated: voting power is decoupled from economic ownership through a dual-class structure that places decisive authority with the family. That concentration implies major decisions will follow the family's long-term strategy, with minority and institutional Klabin shareholders influencing market discipline and capital access but rarely blocking actions.

Why Does Klabin's Ownership Matter?
The ownership profile of Klabin S.A. matters because it shapes long-term strategy, governance, and incentives-concentrated voting control enables large-capex projects while institutional investors supply market discipline and liquidity. This mix directly affects stability, capital allocation, and the company's push into biodegradable packaging.
| Ownership Feature | Business Implication | Why It Matters |
| Founding family voting control | Allows multi-decade investments (Puma II, Caeté) without short-term pressure | Enables execution of R$ 7.8 billion adjusted EBITDA discipline in 2025 and capital planning for 2026 initiatives |
| 34 percent foreign institutional stake | Provides liquidity and external market discipline | Balances family control with governance transparency and access to global capital |
| Net debt/EBITDA at 3.9x (2025) | Shows measured leverage for heavy CapEx cycle | Signals financial discipline compatible with long-term industrial projects |
The clearest business takeaway: Klabin ownership concentrates strategic control with the founding family while institutional shareholders and market metrics constrain excess risk, creating a governance mix that supports heavy, long-horizon investments in biodegradable packaging and industrial expansion.
Strategic Direction and Incentives
Family voting control prioritizes long-term industrial growth and sustainability transitions; management incentives align to multi-year project milestones rather than quarterly payouts. Institutional holders force efficiency and disclosure so projects like Puma II stay financeable and credible.
Stability or Concentration Risk
The structure is stable for high-CapEx work but carries concentration risk: family control can entrench strategy that minority investors may oppose. Still, 34 percent foreign institutional ownership mitigates extreme governance imbalance by supplying market checks and liquidity.
Governance and Decision-Making
Concentrated voting rights speed major decisions on capital allocation and project approvals, reducing activist interference. Accountability depends on transparency to institutional investors and clear reporting on metrics like adjusted EBITDA and leverage.
Overall Business Meaning
For 2025/2026 the ownership mix means Klabin can sustain large-scale investments and lead in biodegradable packaging while maintaining market credibility; investors should weigh family control against liquidity from institutional shareholders when assessing risk and upside.
