French telecoms firm Iliad will be hard-pressed to meet its goal of generating $2 billion in additional annual operating profit at T-Mobile US Inc by cutting costs and slashing prices if its takeover bid is accepted, analysts said. Iliad, which in recent years has shaken up the French mobile market with cheap subscriber plans, bid $15 billion last week for a 56.6 percent stake in T-Mobile, the No. 4 U.S. mobile operator. It would hit those targets by running T-Mobile, majority owned by Deutsche Telekom AG, in an “Iliad-like” way, sources familiar with the takeover bid told Reuters.
