Listen to the news

Health Canada has cleared Moderna (MRNA) to begin a Phase I clinical trial of its mRNA Ebola vaccine targeting the Bundibugyo virus, giving investors another data point on the company’s expanding infectious disease pipeline.

See our latest analysis for Moderna.

Moderna’s US$63.32 share price has been volatile, with a 7.01% 7 day share price gain and a 29.12% 90 day share price return. The 125.98% 1 year total shareholder return contrasts with a weaker 3 and 5 year record. Recent regulatory progress on mFlusiva and the new Ebola candidate trial adds to a period where investors appear to be reassessing both growth potential and the risks around its vaccine portfolio.

Most Popular Narrative: 43.1% Overvalued

Moderna’s most followed narrative pegs fair value at $44.25 per share, which sits well below the recent $63.32 close, so the story leans heavily on future pipeline execution and margin repair.
