The organization over time
Each line starts at 100 in 2020, so what you read is the shape rather than the size: 150 means half as much again as 2020, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2024 to 2025, from $162k to $208k (+28%).

Government-grant reliance: 2020 88% · 2021 84% · 2022 92% · 2025 77%. Grants only. Government contracts and fees sit inside program revenue.

87% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is.
