The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 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 2023 to 2024, from $56M to $62M (+11%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2019 0% · 2020 1% · 2021 2% · 2022 1%. Grants only. Government contracts and fees sit inside program revenue.
2% of MARINERS HOSPITAL INC’s revenue is contributions — more donation-reliant than the typical peer (1% for the typical peer).

Who funds it, year by year
2017 → 2023: the base narrowed from 3 funders to 2 funders, grant income rose $12k → $50k.
2 of 6 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 46% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $6.5M from one payer (the payer shares this organization's board, largest Baptist Health South Florida Foundation Inc). These are real filings, and they are not money MARINERS HOSPITAL INC raised.
From the IRS filings of MARINERS HOSPITAL INC’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
MARINERS HOSPITAL INC leans on a few funders — its largest provides 49% of grant income and the top three 95%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
46% 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. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund MARINERS HOSPITAL INC.
Largest funder’s share by year: 2017 87% · 2018 95% · 2019 95% · 2020 57% · 2021 95% · 2022 67% · 2023 80% — diversifying over time.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Where its funders are
MARINERS HOSPITAL INC draws 100% of its grant income from funders outside Florida, across 4 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $68k arriving through sponsors registered in 2 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
