PORTFOLIO IDEAS CLOSED IN DECEMBER 2023
Neoleukin Therapeutics (NLTX) Breakeven in 5 Months
Neoleukin Therapeutics was a busted biopharma trading at a significant discount to its net cash and exploring strategic alternatives. The strategic review culminated in an announcement of a reverse merger with another clinical-stage biopharma, Neurogene. This prompted arbitrageurs, who were expected liquidation, to scramble for the exits, putting substantial downward pressure on the stock price. The sell-off seemed to create a buying opportunity with downside partially protected by the projected net cash of the combined entity. I expected that the market could start viewing the prospects of the combined entity differently before the closing of the reverse merger. Several aspects gave some confidence that the merger consideration (16% of the combined company + a CVR) could prove more valuable than the NLTX market price at the time. There was also a small chance that shareholders would reject the merger and the company would instead opt for liquidation. Unfortunately, the reverse merger with Neurogene closed in mid-December, and neither a share price re-rating nor liquidation materialized until then. As I had no intention of holding an investment in post-merger Neurogene, I closed the position at break-even levels + the CVR.
