Overview

InvestingPro’s Fair Value models identified Quantum Computing Inc. (NASDAQ: QUBT) as significantly overvalued eleven months before the stock’s near‑48% decline. On 26 August 2025 the share traded at $15.23, which the model deemed 42% above its estimated fair value of $8.80.

Price Movement Validation

Following the warning, QUBT’s price fell steadily, reaching the predicted fair‑value target of $7.92 – a 48% drop from the August 2025 level. As of September 2026 the stock was quoted at $8.70, remaining close to the current fair‑value estimate of $9.30, thereby confirming the accuracy of the early overvaluation assessment.

Financial Fundamentals

At the time of the August 2025 warning, Quantum Computing reported revenue of only $0.263 million and an EBITDA loss of $28.84 million, while its market capitalization exceeded $1 billion. The stock exhibited extreme six‑month volatility, with monthly swings of +68% and –42%, indicating speculative trading rather than fundamentals. The company’s financial health score was 1.26, reflecting weak underlying metrics.

Recent Developments (as of Sep 2026)

Despite a dramatic revenue increase to $9.824 million, EBITDA losses more than doubled to $61.116 million, underscoring persistent cash‑burn concerns. The firm secured a $500 million private placement, announced a strategic collaboration with POET Technologies, and unveiled a new photonic computing system. Nevertheless, these positive developments could not offset the fundamental overvaluation identified in August 2025.
