Barrington downgrades WAG to Mkt Perform from Outperform following WAG's Q4 earnings report. The firm notes that EPS of $0.45 per share was below their estimate of $0.46. Firm says while reported EPS met the consensus, quality of earnings was low, reflecting benefits of a lower tax rate and a one-time vacation accrual adjustment. Firm also notes that while overall SG&A spending remains under tight control, mgmt acknowledged that certain promotional investments failed to yield any sales benefit in the quarter, leading to further margin erosion.
