Actionable Insight ▼ Bearish

Massive ~119% dilution from this priced offering will pressure XRTX shares near term. The $1.88 offering price is a hard ceiling for near-term trading. Monitor for potential further offerings given the company's cash burn and pre-revenue status — the shelf registration remains available for additional draws.
