An extremely volatile trading day ended with Rite Aid’s shares higher on Monday.

Rite Aid’s stock price experienced steep swings throughout the trading day, soaring more than 20% higher than its opening price in morning trading and then falling to near-session lows close to midday. A surge in the stock in the afternoon led to a day-end gain of 8.23% for the stock.

Rite Aid’s shares fell Friday amid reports that it was preparing to file bankruptcy, causing the steep swings.

A new all-time low of $0.71 a share was set by the Philadelphia-based chain on Friday. Since this time last year, Rite Aid (RAD) shares have fallen more than 91%.

According to The Wall Street Journal and Bloomberg, Rite Aid is preparing to file for Chapter 11 bankruptcy. There is about $3.3 billion in debt for Rite Aid, which has been embroiled in a legal battle for allegedly filling illegal opioid prescriptions.

The Department of Justice filed suit against the company in March, alleging it processed “unlawful prescriptions for controlled substances.” This violates the False Claims Act and Controlled Substances Act.

A bankruptcy filing would restructure Rite Aid’s debt, including any legal obligations.

More than 2,200 Rite Aid stores are located in 17 states, making it the seventh largest pharmacy chain in the country.

Following similar opioid lawsuits, Purdue, Endo Pharmaceuticals, and Mallinckrodt have also declared bankruptcy.

According to the Department of Health and Human Services, more than 760,000 people have died from drug overdoses since 1999. Drug overdose deaths involving opioids are expected to account for about 75% of all deaths in 2020.
