Uponor turns 100 years

Uponor’s story began exactly 100 years ago today, as Aukusti Asko-Avonius signed the papers and established a carpentry workshop in Lahti, Finland on 13 August 1918. The workshop quickly grew into the largest furniture supplier in the Nordic countries, and in the 1960’s the company expanded its business further into the plastics industry.

To honour the anniversary year, Uponor has been invited to New York to close the trading at the Nasdaq stock market on Monday, 20 August 2018. At the event, Uponor’s President and CEO Jyri Luomakoski will ring the Nasdaq stock market closing bell and give a speech. Uponor will also receive visibility on the Times Square billboard during the ceremony. The ceremony begins at 15:50 local time (22:50 EET).
