FTSE Russell determines membership for its Russell indexes primarily by objective, market-capitalization rankings and style attributes.

“The inclusion of Eos in the Russell 3000® Index marks an exciting milestone for our company and is a testament to the market reception to our technology and the tremendous opportunity we have in front of us,” said Sagar Kurada, Chief Financial Officer of Eos. “We are pleased to be listed among the distinguished companies in the Russell indexes and look forward to deeper engagement with investors and other key stakeholders.”
