Shares of Rite Aid (RAD) - Get Report  tumbled in premarket trading on Thursday, though recovered at the opening bell, after the struggling pharmacy chain reported a fiscal first-quarter loss almost double from a year ago amid sluggish sales in its retail pharmacy and prescription segments.

Rite Aid stock plunged more than 10% in premarket trading on Thursday after the company reported an adjusted net loss from continuing operations of $7.5 million, or 14 cents a share, compared to adjusted net income of $1 million, or 2 cents a share, a year earlier. 

Analysts polled by FactSet had been expecting a loss of 15 cents a share. Sales dipped to $5.37 billion in the quarter from $5.39 billion in the year-ago quarter.

The stock recovered at the opening of trading, gaining 4.5% at $7.43 by midday.

The company did maintain its fiscal 2020 outlook, which assumes a continued decline in prescription reimbursement rates being partially offset by continued prescription count growth, improvements in drug costs and continued expense control.

Rite Aid said it expects to post a net loss of between $170 million and $220 million, and adjusted per share results of between a 14-cent loss and 72-cent gain on sales of between $21.5 billion and $21.9 billion.
