Tennessee Aquarium: $31.5M Revenue, $28.4M Expenses

The composite efficiency score of 61/100 puts Tennessee Aquarium at C — neither standout nor failing. Some factors run above the median (often reserves) while others run below (often revenue stability or officer-comp ratio).

Tennessee Aquarium reported $31.5M 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. Tennessee Aquarium holds a moderate reserve position relative to its $28.4M in annual expenses — neither fragile nor a large surplus.

Revenue trend is mildly positive across the five-year filing window — modest growth, consistent with stable funding sources keeping pace with organizational costs. Compensation for current officers and key employees runs $1.1M against $31.5M 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. Tennessee Aquarium 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.
