Shares of Rite Aid Corp. fell more than 18% in the extended session Wednesday after the drugstore chain lowered its guidance for fiscal 2021, saying its bottom line was “significantly” hampered by a “soft” cold and flu season, the ongoing pandemic, and “challenging” weather. Same-store sales fell about 5.6% in the quarter ended in February, mostly due to a decline of nearly 37% percent in cough, cold and flu-related categories, the company said. Rite Aid also said it had administered about 1 million COVID-19 vaccines in March to date. The company said it expects fiscal 2021 revenue of about $24 billion, with same-store sales expected to increase about 3.5% compared with fiscal 2020. It called for a net loss between $90 million and $100 million for the year, and an adjusted EBITDA between $425 million and $435 million. Liquidity is about $1.7 billion, it said. Rite Aid is scheduled to report fourth-quarter results on April 15. The stock ended the regular trading day down 2.4%.
