Upturn Advisory & Investor View for ATRA

11/06/2026: ATRA (1-star) is currently NOT-A-BUY. Pass it for now.

Atara Biotherapeutics is a clinical-stage biotechnology company focused on developing off-the-shelf T-cell immunotherapies for cancer and autoimmune diseases. Its main strength lies in its specialized EBV T-cell platform, which aims to provide accessible treatments through allogeneic technology. The company's growth story hinges on successfully navigating clinical trials and expanding into autoimmune indications to increase its market reach. However, it faces significant risks including financial volatility, high cash burn, and intense competition from larger, better-funded biotechs. The stock may suit growth-oriented investors with a high tolerance for risk, though potential investors should monitor clinical data readouts and capital management closely.

Upturn Scorecard

Upturn Star Rating

★★★★★
ATRA receives a 3-star rating, supported by solid company fundamentals. The rating is constrained by weak price momentum.

Company Fundamentals

★★★★★
ATRA has solid overall fundamentals (4 stars), with moderate financial health, solid growth momentum, and solid ownership. In FY2025 versus FY2024, strong earnings growth (+138.3%) and strong profitability (net margin 27.1%) are partially offset by weak cash generation (FCF margin -42.2%), negative revenue growth (-6.3%).

Financial Health Rating

★★★★★
ATRA's financial health is supported by solid profitability, including gross margin of 82.4% and operating margin of 29.7%. Liquidity is soft (2 stars), which helps explain the 3-star overall score.

Growth Momentum Score

★★★★★
Earnings growth is ATRA's strongest growth driver at +138.3% FY2025 versus FY2024 (strong, 5 stars). By comparison, free-cash-flow growth (+26.1%, solid) is also solid, while revenue growth (-6.3%, negative) holds the profile back, so recent growth is not broad-based across the business.

Ownership

★★★★★
Institutional ownership is 57.2% and approximately 46.1% of outstanding shares are publicly tradable, supporting liquidity and institutional participation. Insider ownership of 16.80% supports management-shareholder alignment.

Unit Economics (Per $1K Revenue)

★★★★★
ATRA generates approximately $824 of gross profit, $297 of operating income, and $-422 of free cash flow for every $1,000 of revenue. Based on FY2025 results. Weak margins and weak cash conversion support a 3-star rating, while capital efficiency is weak.

Economic Dimensions

★★★★★
Effective Tax Rate: 0.09%

Quantitative Style Profile

★★★★★
ATRA has a relatively low-volatility profile. Weak momentum is the primary drawback, while valuation that is moderately attractive rather than deeply discounted.
