Alex Albon has signed a new long-term deal with Williams, until the end of the 2026 season at least.
The Thai driver, whose existing contract was due to expire at the conclusion of the 2025 campaign, has put pen to paper on fresh terms with the team he joined in 2022.
After finishing seventh in last season's World Constructors' Championship standings, Williams are ninth after a slow start to 2024.
While the length of the new deal is uncertain, it will take Albon into Formula One's new regulation period, which begins in 2026, and the 28-year-old is excited by Williams' future.
"This is a long-term project that I really believe in and want to play a key role in, which is why I have signed a multi-year contract," he said.
"The journey will take time, but I am confident we are building the right team to move forward and achieve great things in the years to come.
"It has been a difficult start to the year, but since joining Williams, we have made significant progress together, and I have seen huge changes happening behind the scenes to take us back to the front of the grid."
Team principal James Vowles added: "We are delighted to secure Alex's long-term future with Williams Racing.
"He has exceptional talent, technical input and dedication to the cause and this is a huge vote of confidence in Williams and the journey back to competitiveness that we are on.
"Since joining, Alex has consistently demonstrated his ability to perform under pressure, and signing him for the long-term is a big piece of the puzzle of moving us up the grid."
