NEW YORK ( TheStreet) -- Walgreen's ( WAG) latest purchase, Duane Reade, reported a wider fourth-quarter loss on Tuesday.

The New York-based drugstore recorded a loss of $84.8 million from $17.4 million a year earlier. The results included charges of $59.5 million reflecting the probability of a near-term mandatory redemption of its preferred stock.

Sales remained about flat at $465 million, while same-store sales jumped 2.6%.

Walgreen announced last month that it is acquiring Duane Reade for $1.08 billion. The purchase will add 275 Duane Reade stores to Walgreen's portfolio. The deal also includes the assumption of $457 million in Duane Reade's debt.

The deal is expected to close this fiscal year, which ends Aug. 31.
