The Premier League champions confirmed on Thursday that they had exercised their option to buy the 24-year-old, who has signed a five-year contract at the Emirates Stadium.
Reports indicated that Arsenal paid 34.5 million pounds, plus add-ons, to secure Hincapie's services following an impressive debut campaign in North London.
Hincapie played an important role in Arsenal's title-winning season, making 25 Premier League appearances as the club claimed the English top-flight crown for the first time in 22 years. His versatility and consistency helped strengthen Mikel Arteta's defence throughout the campaign.
Before moving to England, Hincapie was a key figure in Bayer Leverkusen's historic 2023-24 season, when the German side won the Bundesliga title without suffering a single defeat.
The defender is currently representing Ecuador at the 2026 FIFA World Cup and has started his country's opening two Group E matches. He is expected to be in action again when Ecuador face Germany later on Thursday.
Aston Villa are pushing to complete a deal for Joao Palhinha and have stepped up their efforts to sign the Bayern Munich midfielder, following his stint at Tottenham last season.
Youri Tielemans has explained why he finally made the move to Manchester United, admitting the opportunity was too significant to turn down despite his gratitude towards Aston Villa.
Matthias Jaissle has given an early glimpse of what to expect from him after opening up on his "emotional" personality on the touchline.
Chelsea have completed the signing of Pep Chavarria from Rayo Vallecano, with the left-back joining on a five-year contract.
