Red Bull GmbH, the F1 team’s parent corporation based in Austria, exonerated the 50-year-old on Wednesday of any wrongdoing.
He had been under investigation for allegedly acting inappropriately with a female coworker.
In a statement, Horner stated, “I have always denied the allegations, but I won’t comment on anonymous speculation.”
“I completely cooperated with the independent investigation at every stage, respecting its objectivity.
“An independent specialized barrister carried out a comprehensive and impartial inquiry, which resulted in the complaint being dismissed.
“I remain fully focused on the start of the season.”
Throughout the process, Horner has refuted the charges, and last week he was in Bahrain for the team’s pre-season testing and the introduction of their 2024 vehicle.
