Looks like someone didn't like holding early today and then had a change of mind, buying it all back. Maybe they read your post OR just maybe a market maker wanted to draw attention to the stock with a high volume day, and it just happens to coincide with the news release you found:
Steve and Les talk at 2 minute mark on Coronavirus update by KVUE(abc) TV Texas on mitigation program for BACK TO WORK SAFELY. The program is HIPA compliant, a $2 fee is covered by the testing program and QMC "is in talks with state and federal leaders".
