Summary

  • Concentra Biosciences' $3/share + CVR bid for SLRN is superior to the ALMS stock-for-stock offer, presenting us with a 20% spread in favor of its bid.
  • SLRN's remaining Phase 2 asset, Lonigutamab, has shown disappointing results, making Concentra's cash offer more attractive compared to ALMS's uncertain prospects.
  • Despite this, the recent rejection of Concentra's offer makes it hard to justify the continued premium at which Concentra bid trades above the ALMS offer.
  • Significant stake reduction from the largest shareholder further supports the argument against the new bid from Concentra.

I have been managing friends and family portfolio for the last 7 years, mostly being a disciple of the value investing school. More recently, I have shifted more towards special situation investing, mostly due to my current employment as an analyst in a small/mid-cap focused event-driven fund. Given the focus on special situations, I have gravitated more towards being a generalist, but I have definitely learned to pick my spots and not get involved with overly complicated setups or businesses. Mostly focusing on parts of the market that are overlooked by investors, whether due to liquidity, size, or particular unloved structures like MLPs. Barring a few exceptions, I intend to share both event-driven and off-beaten deep value stocks in the small-cap space with the Seeking Alpha community. I have a bachelor's degree in Economics and I a master's degree in Finance. For the last 3 years, I have been working in a European special situations-focused fund as an equity analyst.
