What Happened

The offering was upsized from an earlier reported $300 million offering. The move has drawn attention from multiple financial news outlets and triggered chatter on social media platforms.

Retail traders on social media platforms have highlighted the offering as a key development, with some noting the stock’s recent FDA win as a contrast to the current offering. The company has seen recent insider selling, with director Jason P. Rhodes and CFO Erick Lucera selling shares in June and July. The stock has been volatile, with insiders reporting 13 sales totaling $41.6 million in the last 90 days.
