PCMag.com picked up on the company mentioning the possibility of exclusivity contracts ending in its most recent SEC filing, for the first time:

"As these exclusivity arrangements end, we expect to continue to offer such handsets (based on historical industry practice)," writes AT&T in the filing. "And we believe our service plan offerings will help to retain our customers by providing incentives not to move to a new carrier."
