Dade Hayes Finance EditorAMC Entertainment plans to sell 20 million of its Class A shares, netting $47.7 million, as it contends with ongoing shutdowns of many of its movie theaters and a withdrawal of studio films from the 2020 release calendar.COVID-19 hampered the release of Tenet in August and aside from less-expensive, targeted titles, wide releases have shifted to either later release dates or streaming debuts.The company disclosed the move in an SEC filing Monday.
