A. H. Robins Co. shareholders, who had planned to endorse a competing offer to a takeover bid approved by the troubled drug company’s management, said they had received new information and plan to continue meeting over the weekend, a lawyer for the group said. Robins, the maker of the Dalkon Shield contraceptive, filed a Chapter 11 bankruptcy plan contingent on its takeover by a France’s Sanofi S. A. The companies have not placed a value on the offer because of its complexity. However, shareholders believe that the Sanofi bid undervalues Richmond, Va.-based Robins. The group has continued to meet Sanofi and previous bidders.
