Uber Technologies (UBER) and Grubhub (GRUB) continued their merger discussions over the weekend as GrubHub rebuffed Uber’s latest offer of 1.9 per share, Cara Lombardo of Wall Street Journal reports, citing people familiar with the matter. Uber CEO Dara Khosrowshahi told GrubHub CEO Matt Maloney that he might be able increase the offer to 1.925 Uber shares, but that is still well below the price Grubhub had been seeking, Lombardo added. An agreement, should there be one, is still unlikely in the next few days, sources told the Journal.
