AT&T told SEC in filing Tues. that company had held “exploratory discussions” with Dobson Communications on potential transactions. Last week, AT&T Wireless finalized purchase of $200 million of preferred stock in Dobson. If that series of preferred stock were exchanged into convertible preferred, AT&T Wireless said its stake in Dobson would rise to 11.6% from 4.6%. Dobson and AT&T have evaluated “strategic alternatives” concerning AT&T Wireless’s stake in Dobson, SEC filing said. Among potential options outlined were loans that would be secured with some of Class A shares of common stock that AT&T owns. Another option would be acquisition, merger or asset sale, companies said. Dobson subsidiary won 14 PCS licenses for $546 million in recently completed FCC C-block auction.
