Actionable Insight ▼ Bearish

Watch for the pricing date and final offering size in the next 1-2 days. The effectiveness notice typically precedes pricing by 1-2 business days. Given the company's dilutive history, expect the offering to be fully placed, likely at a steep discount to the current market price.
