The organization over time
Each line starts at 100 in 2023, so what you read is the shape rather than the size: 150 means half as much again as 2023, 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 at each year end, in dollars. The largest one-year move in total assets was 2023 to 2024, from $213k to $228k (+7%).
