Upturn Scorecard

Upturn Star Rating

LUNG receives a 3-star rating, supported by solid analyst coverage. The rating is constrained by soft unit economics, and weak price momentum.

Company Fundamentals

LUNG has moderate overall fundamentals (3 stars), with moderate financial health, moderate growth momentum, and solid ownership. In FY2025 versus FY2024, moderate earnings growth (+4.2%) is partially offset by soft cash generation (FCF margin -36.4%), moderate revenue growth (+8.0%), soft profitability (net margin -59.7%).

Financial Health Rating

LUNG's financial health is supported by solid liquidity, including working-capital and asset support (WC/assets 63.1%). Cash strength is soft (2 stars), which helps explain the 3-star overall score.

Growth Momentum Score

Revenue growth is LUNG's strongest growth driver at +8.0% FY2025 versus FY2024 (moderate, 3 stars). Earnings growth (+4.2%, moderate) and free-cash-flow growth (+0.3%, moderate) are also constructive, though not equally high across every growth measure.

Ownership

Institutional ownership is 62.8% and approximately 87.6% of outstanding shares are publicly tradable, supporting liquidity and institutional participation. Insider ownership of 4.64% provides only moderate management-shareholder alignment.

Morgan Stanley - Brokerage Accounts 9.30%
Soleus Capital Management, L.P. 6.49%
BlackRock Inc 6.20%
ExodusPoint Capital Management, LP 4.53%

Unit Economics (Per $1K Revenue)

LUNG generates approximately $742 of gross profit, $-593 of operating income, and $-364 of free cash flow for every $1,000 of revenue. Based on FY2025 results. Strong cash conversion and healthy margins support the rating, although capital efficiency remains below the highest tier.

Economic Dimensions

Effective Tax Rate: -1.17% (Tax Credit)

Quantitative Style Profile

LUNG has a liquid, relatively low-volatility profile. Weak momentum is the primary drawback.
