Ecology and Environment Inc is no longer a publicly traded security. The company, an environmental consulting and energy development firm based in Lancaster, New York, was acquired by Canadian engineering firm WSP Global Inc in a cash merger that closed on December 31, 2019. Each share of common stock was converted into $15.00 in cash. The company filed a deregistration notice with the SEC in early 2020. The ticker EEI no longer trades on Nasdaq or any other exchange, and no filings have been made under the company's CIK since that date.
This report documents the finding that EEI is a defunct ticker. The company's last substantive filings are the fiscal year 2019 annual report and the Q4 FY2019 quarterly report, both completed before the merger closed. The stock was delisted from Nasdaq following the merger, and the company ceased to exist as an independent public entity. Investors who held EEI shares at the closing received the $15.00 per share merger consideration. A special dividend of $0.50 per share was declared in late December 2019.
