Standing thesis

The standing, falsifiable read: what has to stay true, and what would break it.

Special situation

Intact: The reason to own it still holds.

The bull case

Zenas BioPharma plans to submit a key drug application in Q2 2026. The company has enough cash to operate through Q2 2029. Positive trial results support future approval chances.

The bear case

Zenas is still losing money and expects negative earnings in 2026. The drug approval is not guaranteed. The company depends on raising more funds.

What's priced in

The market values Zenas near $9 per share, implying strong growth. Our fair value matches this but risks remain in drug approval and profitability.
