Kokko becomes deputy CEO in December and chief executive on 1 April 2027, after five years on Arvo's board of directors. The nomination committee that selected him sits under the supervisory board, one level above that board; Arvo has not disclosed whether he keeps his seat.

On 1 September 2026, Arvo Sijoitusosuuskunta released as inside information that Teemu Kokko will become its chief executive. He starts as deputy CEO in early December 2026 and takes over on 1 April 2027.

Kokko joins from the insurance underwriter Arch Underwriters Europe Oy, where he is regional director. He has also been a member of Arvo's board of directors since 2021.

The committee sits one level up

Arvo is a cooperative. Its highest governing body is not the board of directors but the supervisory board which represents the members, has 18 to 30 seats, serves three-year terms and meets roughly three times a year. That body appoints a nomination committee from among its own members.

When Jari Pirinen announced on 8 September 2025 that he would retire in spring 2027 on turning 66, Arvo said management succession planning sat with that committee, and supervisory board chair Tuomo Tamminen said it would report on progress later.

So the body that selected Kokko is not the board Kokko sits on. It is drawn from a members' organ and answers to the members.

In a listed limited company there is no such layer. The board appoints the chief executive itself. That is the comparison for any Finnish board weighing one of its own directors as a successor: Arvo can point to a committee above the board; a listed board has to show its process instead.

Two things Arvo has not disclosed. The release does not say whether Kokko remains a member of the board of directors once he becomes deputy CEO in December or chief executive in April. Nor does it say how the board handled his candidacy, he has been a director throughout the period covered by the succession process announced in September 2025.

Arvo's board was re-elected in February 2026 and comprises Marjo Kolehmainen as chair (a director since 2018, chair since 2022), Mika Kiljala as vice chair (director since 2017), Juha Laakkonen and Kokko (both since 2021), and Titta Mantila (since 2024).

The handover runs 19 months end to end

Retirement flagged in September 2025. Successor named in September 2026. Four months as deputy chief executive from early December 2026. Handover on 1 April 2027. Pirinen then moves to special duties on the board of directors from that date, takes accrued leave, and retires on 31 May 2027.

That is a longer and more pre-committed sequence than Helsinki practice, where chief executive changes are often announced with an interim in place and a search still running.

Oura has filed publicly for a Nasdaq listing in the United States and, according to reporting by The Wall Street Journal, intends to list during September. The Finnish smart ring maker submitted a confidential filing in May. The prospectus arrives with a board reshaped for US public markets, and a Nordic presence now outnumbered on it.

The prospectus filed with the U.S. Securities and Exchange Commission shows revenue of $1.21 billion for the nine months ended 30 June 2026, the first three quarters of a fiscal year that ends 30 September, against $697.6 million in the same period a year earlier, a rise of 74%. Full-year FY2025 revenue was $907.9 million, against $406.8 million the year before. The net loss attributable to common shareholders over the same nine months was $924.3 million, compared with $182.8 million a year earlier.

Oura shipped 3.1 million rings in the nine-month period, against 1.8 million a year earlier. Membership revenue reached $240.5 million, up 121%, and paid members doubled to 5 million, the recurring line that will matter most to public-market investors, and the one that turns a hardware company into a subscription business.

The headline loss sits beneath a $985m deemed dividend

Before the deemed dividend attached to preferred shares, Oura's net result for the period was a profit of $60.8 million, against $1.6 million a year earlier. The $924.3 million figure emerges after a $985 million deemed dividend to holders of redeemable convertible preferred shares is deducted. The comparable deemed dividend a year earlier was $184.4 million.

Oura raised more than $1.2 billion privately before this filing. A Fidelity-led round in October 2025 valued the company at $11 billion. The listing could raise up to $3 billion for the company and some of its backers at a valuation exceeding $16 billion, Bloomberg reported on 24 August 2026, a repricing of roughly 45% in under a year. 

The new board adds Robinhood's IPO-era CFO and Wolt's founder

Oura said on 2 September that it will appoint Jason Warnick, Leslie Kilgore, Miki Kuusi and David Sze as directors.

Warnick spent seven years as chief financial officer of Robinhood, where he helped take the company public and through its subsequent life as a listed business. He retired from the role earlier this year and was succeeded by Shiv Verma. Before that he spent nearly two decades at Amazon across finance, investor relations, audit and enterprise risk, and began his career as a CPA at Deloitte & Touche.

Kilgore sits on the boards of Netflix and Pinterest, and has previously served on those of LinkedIn, Medallia and Nextdoor. She was chief marketing officer at Netflix, and held earlier positions at Amazon, Procter & Gamble and Booz Allen Hamilton.

Kuusi co-founded Wolt and led it as chief executive from 2014 until DoorDash acquired the company in 2022. He now oversees DoorDash's international business and serves as chief executive of London-based Deliveroo. 

Sze is a partner at Greylock Partners, where he led investments in Facebook, LinkedIn, Roblox and Pandora. He previously held senior operating roles at Excite and Excite@Home.

The four join Timo Ahopelto, Dennis Durkin, chief executive Tom Hale, Wen Hsieh, Eurie Kim and chairman David Shuman on the board.

"Adding Jason, Leslie, Miki, and David strengthens our board with leaders who know what it takes to build and scale category-defining global businesses," Hale said in the company's statement.
