▼(-50.02% Downside)
Action:Reiterated
Date:06/17/26
The score is primarily weighed down by weak financial performance (minimal revenue, large losses, and sustained negative free cash flow) and a bearish technical setup (price below major moving averages with negative MACD). A low-leverage balance sheet and a positive governance vote provide some support, but they are not enough to offset ongoing cash burn and downtrending price action.
Positive Factors
Platform focus on T‑cell dysfunction
Lyell’s platform explicitly targets T‑cell dysfunction and exhaustion and develops engineered cellular therapies for solid tumors. A platform addressing a core biological failure mode supports multiple program opportunities, persistent IP value and durable differentiation versus single‑asset peers.
Negative Factors
Large and persistent cash burn
Sustained annual cash outflows in the low hundreds of millions create ongoing financing needs and elevate dilution risk. Large burn limits internal runway, forces reliance on external capital or collaborations, and constrains the company’s ability to advance multiple clinical programs simultaneously.

Lyell Immunopharma Financial Statement Overview

Summary
Financials reflect a development-stage biotech profile with very limited and declining revenue (TTM ~$31K; -13.9% vs prior period), large operating and net losses (TTM EBIT ~-$192M; net income ~-$246M), and significant cash burn (TTM FCF ~-$134M; FCF growth -10.9%). The balance sheet is a relative support with low leverage (debt-to-equity ~0.14), but multi-year equity decline and ongoing burn imply continued financing/dilution risk.
