Nike CEO Mark Parker on Tuesday said the company’s use of Colin Kaepernick in the brand’s recent “Just Do It” spots has resulted in “record engagement with the brand.”

Nike announced on the earnings call that its revenue over the past three months, a period which ran until Aug. 31, was up 9 percent to $9.9 billion. The last day included was days before the first Kaepernick spots appeared.

Since the Kaepernick ads ran, Nike’s stock has risen 6.25 percent, adding $6.38 billion to the company’s value.

The bet on Kaepernick has paid off in spades.
