Jennifer Maas TV Business WriterAT&T CEO John Stankey told investors he expects HBO Max to recoup all of the subscribers lost last fall after WarnerMedia pulled HBO from the Amazon Prime Video Channels marketplace in September amid ongoing agita in the TV industry about the fees Amazon takes for facilitating sales of subscription TV services.During AT&T’s hourlong fourth-quarter earnings call with investors on Wednesday, Stankey also noted that market conditions have spurred price hikes by HBO Max rivals, which means that HBO Max is not the most expensive of the major domestic players at present. Stankey didn’t mention Netflix by name, but the inference was clear.Last October, AT&T reported that HBO and HBO Max lost about 1.8 million subscribers in the third quarter after the disengagement from Amazon in the previous month.
