Analysis of NRx Pharmaceuticals' Cash Burn and Market Outlook
- Cash Burn Situation: As of December 2025, NRx Pharmaceuticals had cash reserves of $7.8 million and a cash burn of $14 million over the past year, indicating a cash runway of approximately seven months, although analysts expect the company to break even before then.
