Johnny McNicholl has become the latest high-profile player to sign a new deal with the Scarlets.
Last week Grand Slam winners Jonathan Davies, Ken Owens and Rob Evans penned new contracts.
The 28-year-old qualifies for Six Nations champions Wales on residency in December.
Wayne Pivac, who will replace Warren Gatland as Wales head coach at the end of the 2019 World Cup, is delighted to see the deal done.
“It is great news that Johnny has signed a new contract. He has been one of the most dangerous attacking threats in the PRO14 in recent years and played a big part in us reaching successive finals and a European semi-final.
“With the news of Jon, Ken and Rob signing last week, this is another significant signing for the Scarlets. The squad is looking strong for next season.”
A potent attacking runner, he made an immediate impact at Parc y Scarlets with a try on his debut against Leinster and has gone on to touch down 27 times in 59 appearances, including a memorable hat-trick in last season’s PRO14 final in Dublin.
“I am happy that everything has been finalised and I’m staying at the Scarlets,” said McNicholl.
“Myself and my family are settled here in Wales and have been made to feel very welcome.
“We have had some great success over the last couple of years and hopefully there is more to come.
“I’m looking forward to reconnecting with my former Crusaders coach Brad Mooar and feel there are exciting times ahead.”
