** Q3 sales came in at SEK 6,659 mln, below the SEK 6,873 mln estimate seen in LSEG poll, while adjusted EBITDA of SEK 915 mln beat the SEK 850.4 mln estimate

** In light of "impressive trends" at peer Twilio TWLO.N, and given Sinch shares being already up 64% YTD, J.P.Morgan says the "mixed" results may be considered "a little underwhelming"

** Twilio shares jumped 11% on Friday, after the group delivered better-than-expected sales and hiked its revenue growth outlook

** Sinch stock is on track for on track for its worst day since April if losses hold
