One of the three suitors for Leighton Holdings Ltd.'s (LEI.AU) Thiess Waste Management unit is said to have dropped out of the running after final offers in the drawn-out sale were due last Friday, The Australian Financial Review reported Monday, without citing a source for the information.

The newspaper said it hasn't been confirmed that Sita, a joint venture between France's Suez Environment SA (SEV.FR) and Singapore's Sembcorp Industries Ltd. (U96.SG), has dropped out of the auction.

It added that Suez's shares dropped to a record low late Thursday after the utility posted a profit warning and warned "the downward trend observed in waste activities in the first quarter in Europe has accelerated in the second."

Exclusivity is expected to be granted as early as Monday to either Transpacific Industries Group Ltd. (TPI.AU) or Germany's Remondis, the AFR reported. If an acceptable offer isn't received, Leighton may abandon the sale, it said.

A spokesman for Leighton wasn't immediately available to comment.
