The remarks come after Hoettges reportedly told DT's board he considers a sale of 67%-owned T-Mobile USA (TMUS -1.8%) unlikely in the near-term, given regulatory opposition to a bid from Sprint (S -3.6%) and parent SoftBank (SFTBF, SFTBY).
Citing T-Mobile USA's aggressive investments, DT now expects its 2015 free cash flow to only be up "slightly" from 2014 levels. The carrier previously forecast 2015 FCF to rise to €6B ($8.3B) after hitting €4.2B ($5.8B) in 2014.
Sources tell Bloomberg Hoettges is now "taking a long-term view in the U.S.," and is focused on converting more of T-Mobile's giant prepaid base into postpaid subs.
DT shares fell 3.6% in Frankfurt. Both T-Mobile and Sprint are selling off in U.S. trading.
