National Aquarium Inc: $55.6M Revenue, $54.1M Expenses

The efficiency rubric puts National Aquarium Inc at a B grade: a composite of 73/100 that lands above the national midpoint. The grade reflects solid financial reserves alongside reasonable officer compensation and steady revenue.

National Aquarium Inc reported $55.6M in 2023 revenue — a mid-sized nonprofit by U.S. standards. Organizations in this bracket typically operate with a small permanent staff, project-based program structures, and modest reserves. Financial health is a strength: National Aquarium Inc carries a healthy operating-reserve cushion against $54.1M in annual expenses, the kind of balance-sheet stability that helps an organization weather funding gaps without cutting programs.

Five-year revenue has grown modestly. National Aquarium Inc is not expanding rapidly but is not shrinking either; the trajectory is consistent with stable donor and grant relationships. Compensation for current officers and key employees runs $2.1M against $55.6M in revenue — within the band third-party charity raters typically consider reasonable for an organization of this size and complexity. This is an aggregate across all listed officers, not a single executive's salary. National Aquarium Inc works in Environment & Animals — environmental, conservation, animal-welfare, and natural-resources programs. The sector spans large international conservation groups and small local land trusts; the financial profile varies accordingly.
