Who Really Stands Behind Vaisala?
Vaisala operates a dual-class share system: unlisted Series K shares control voting, while listed Series A shares hold economic rights. The Vilho, Yrjö and Kalle Väisälä Foundation together with the Väisälä family hold Series K and control the company despite owning about 15% of shares; institutional investors (pension funds, ESG funds) dominate A-share economics.
Main owner: Väisälä family and foundation control
The Vilho, Yrjö and Kalle Väisälä Foundation plus Väisälä family hold unlisted Series K shares that represent ~15% of total shares but command over 75% of voting power, giving them de facto control over Vaisala's strategic direction.
Other important owners: Finnish pension funds and international institutions
Listed Series A shares carry economic interest; Ilmarinen holds ~11.5% and Varma ~4.2% as of mid-2025, while international ESG-focused funds pushed non-Finnish A-share ownership above 25%.
Ownership model: dual-class public company
Vaisala is publicly traded on Nasdaq Helsinki via Series A shares for investors, while founder-led Series K shares are unlisted and concentrated in family and foundation hands, creating a founder-controlled public company.
Ownership concentration: voting power concentrated, economic ownership broader
Voting control is highly concentrated with the Väisälä foundation/family; economic ownership is more distributed among institutional investors, notably pension funds and growing international holders.
Insider/founder stakes: significant governance influence
Insiders (founding family and foundation) have limited economic exposure but majority voting, enabling long-term continuity and influence over board appointments and strategy despite minority A-shareholding.
Current ownership picture: founder-led governance, institutionally financed economics
By mid-2025 Vaisala shows founder-led governance through Series K voting control and broad institutional economic ownership via Series A, with pension funds and ESG investors shaping financial expectations.
Who Really Stands Behind the Company
Vaisala ownership splits control and economics: the Väisälä family and its foundation hold decisive voting power via Series K, while listed Series A shareholders-led by Finnish pension funds and growing international ESG investors-hold the economic stake.
- Vilho, Yrjö and Kalle Väisälä Foundation and Väisälä family command voting control via Series K shares
- Ilmarinen Mutual Pension Insurance Company (~11.5%) and Varma (~4.2%) are major A-share economic holders
- Voting power is concentrated; economic ownership is relatively dispersed among institutions and international investors
- The defining feature is a dual-class structure separating Vaisala ownership (economic) from voting control, keeping founder-led governance

How Did Ownership Change Along the Way at Vaisala?
Vaisala ownership shifted from a tightly held founder-led firm to a public company with widening institutional stakes. Key moves: founder family control after 1969, public listing and dual-class shares in 1994, and rising institutional A-share ownership 2021-2024 with share buybacks 2024-2025 to align management incentives.
| Ownership Event or Period | What Changed | Why It Mattered |
|---|---|---|
| 1936-1969: Founding and founder control | Mittari Oy founded by Professor Vilho Väisälä; equity concentrated in Väisälä family and scientific associates | Secured patents and IP, kept R&D decisions internal; enabled technology-focused growth |
| 1969-1994: Heir and foundation ownership | Shares moved to heirs and related foundations after Vilho Väisälä's death | Maintained long-term orientation and protection of IP; limited external capital access |
| 1994: Helsinki Stock Exchange listing | Vaisala listed on Helsinki (Nasdaq Helsinki) and instituted a dual-class share structure | Opened public capital markets while shielding control from hostile takeovers; enabled larger financing and M&A flexibility |
| 2021-2024: Institutional accumulation of A shares | Institutional ownership of A shares rose from ~35% to ~52%, driven by investor interest in life-science and battery markets | Shifted shareholder base toward institutions, increasing governance scrutiny and liquidity |
| 2024-2025: Share repurchases for incentive plans | Repurchases totaling roughly €15 million to fund management incentive plans | Aligned executive interests with shareholders; modestly concentrated ownership and reduced free float |
The clearest pattern: steady institutionalization of Vaisala ownership-moving from family/foundation control toward a larger institutional A-share base-while corporate mechanisms (dual-class shares, targeted buybacks) preserved strategic control and insulated long-term R&D focus.

Who Really Calls the Shots at Vaisala?

| Board of Directors (chaired by Ville Voipio; Vice Chair Raimo Voipio) | Governance oversight, strategic approval, compliance with Finnish Corporate Governance Code | Serves as institutional bridge between family bloc and public A-shareholders; legitimizes family control |
