Mersana Therapeutics Financial Statement Overview

Summary

Mersana Therapeutics is under significant financial stress, with negative equity, declining revenues, and substantial net losses. The negative cash flow and reliance on external financing further highlight the financial challenges.

Income Statement

Mersana Therapeutics shows a volatile revenue trajectory with significant net losses. The TTM data indicates a gross profit margin of 100% due to revenue equaling gross profit, but the net profit margin remains negative at -217.58%, reflecting substantial expenses. Revenue declined by 16% from the previous year, and the EBIT and EBITDA margins are also negative, indicating ongoing operational challenges.

Balance Sheet

The company's balance sheet reveals financial strain, with negative stockholders' equity indicating liabilities exceeding assets.
