Beal has spent the last two seasons as part of a highly ambitious Suns project alongside Kevin Durant and Devin Booker.
The failure of this 'Big 3', which only managed to compete in one round of the playoffs, prompted the Suns to initiate a roster rebuild, including the recent trade of Kevin Durant to the Houston Rockets.
Plagued by injuries for years, Beal never reached his peak performance in Phoenix. Last season, he recorded his lowest scoring average (17 points) in a decade.
After trading Durant, the Suns had been in talks for weeks regarding Beal's exit, who is among the highest-paid players in the NBA.
Ultimately, the former Wizards shooting guard consented to be released by forfeiting $13.9 million of the $110 million the Suns were due to pay him over the final two years of his contract, as reported by ESPN.
Phoenix will be able to distribute that amount over five years, allowing them more salary-cap flexibility to sign other players.
As a free agent, Beal intends to sign with the Clippers on a two-year, $11 million deal, according to his agent, Mark Bartelstein, who spoke to ESPN.
The Clippers have been active in the transfer market as they aim to strengthen a roster centered around veterans James Harden and Kawhi Leonard.
The franchise, owned by billionaire Steve Ballmer, has already enhanced its inside game with the addition of power forwards John Collins and Brook Lopez from Utah and Milwaukee.
ESPN noted that the Lakers, Heat, Bucks, and Timberwolves were also teams interested in acquiring Beal.
