The 18-year-old put pen to paper on a deal which will keep him at the Swabian club for the next three and a half years.
Werner, who has been with the three-time Bundesliga champions since the age of seven, became the youngest goalscorer in Stuttgart's 120-year history earlier this season with his first of four goals in 21 Bundesliga appearances. "VfB are my club, since I was very small," said Werner. "That's why I'm delighted with this contract. I've come up through the youth teams and really am happy here. I'd like to learn even more and am pleased to be able to do that at this club."
Werner has already shown more than just glimpses of his talent this season. "He's got exceptional quality and his strengths are predominantly his pace and goalscoring instinct," said sporting director Fredi Bobic. "Timo's doing a really top job in his first year as a Bundesliga professional. We want to support him as best we can along his path and we're sure we're going to have a lot more joy with him."
