Dr. Matthew D. Cain submitted his expert report supporting class certification in In re Emergent BioSolutions Inc. Securities Litigation (Case No. 1:21-cv-00574), with econometric analysis and statistical modeling provided by Fideres.

The analysis evaluates whether Emergent BioSolutions stock traded in an efficient market where material information was promptly reflected in share prices. Fideres conducted comprehensive trading volume analysis and examined bid-ask spread patterns, applying statistical techniques to measure price responsiveness to material disclosures.

Cain’s expert testimony documented significant abnormal trading activity and price movements coinciding with corrective disclosure periods, with statistical analysis showing clear correlation between information release timing and market price adjustments.
