MILAN (Reuters) -Teleperformance shares plunged to a 7-year low on Wednesday over concerns artificial intelligence (AI) will disrupt the French call centre firm's business. Two traders and a Midcap Partners analyst linked the drop to a statement by Swedish fintech company Klarna which spoke of a boost to its results from its AI customer service assistant, powered by Open AI. Teleperformance shares were down 19% to 107.9 euros in Paris at 1415 GMT, off lows for the day but still on track for their largest one-day decline since November 2022.
