New York, New York--(Newsfile Corp. - January 24, 2023) - WHY: Rosen Law Firm, a global investor rights law firm, reminds purchasers of the securities of ESS Tech Inc. (NYSE: GWH) between August 11, 2022 and December 7, 2022, both dates inclusive (the "Class Period"), of the important March 13, 2023 lead plaintiff deadline.

SO WHAT: If you purchased ESS Tech securities during the Class Period you may be entitled to compensation without payment of any out of pocket fees or costs through a contingency fee arrangement.

WHAT TO DO NEXT: To join the ESS Tech class action, go to or call Phillip Kim, Esq. toll-free at 866-767-3653 or email pkim@rosenlegal.com or cases@rosenlegal.com for information on the class action. A class action lawsuit has already been filed. If you wish to serve as lead plaintiff, you must move the Court no later than March 13, 2023. A lead plaintiff is a representative party acting on behalf of other class members in directing the litigation.

WHY ROSEN LAW: We encourage investors to select qualified counsel with a track record of success in leadership roles. Often, firms issuing notices do not have comparable experience, resources, or any meaningful peer recognition. Many of these firms do not actually handle securities class actions, but are merely middlemen that refer clients or partner with law firms that actually litigate the cases. Be wise in selecting counsel. The Rosen Law Firm represents investors throughout the globe, concentrating its practice in securities class actions and shareholder derivative litigation. Rosen Law Firm has achieved the largest ever securities class action settlement against a Chinese Company. Rosen Law Firm was Ranked No. 1 by ISS Securities Class Action Services for number of securities class action settlements in 2017. The firm has been ranked in the top 4 each year since 2013 and has recovered hundreds of millions of dollars for investors. In 2019 alone the firm secured over $438 million for investors. In 2020, founding partner Laurence Rosen was named by law360 as a Titan of Plaintiffs' Bar. Many of the firm's attorneys have been recognized by Lawdragon and Super Lawyers.

DETAILS OF THE CASE: According to the lawsuit, defendants throughout the Class Period made false and/or misleading statements and/or failed to disclose, among other things, that: (1) the purported agreement with Energy Storage Industries Asia Pacific ("ESI") was in fact an undisclosed related party transaction because ESI was a de-facto subsidiary of ESS masquerading as third-party client; (2) ESS misled investors with their partnership announcement to signal business success to investors; and (3) as a result, Defendants' statements about its business, operations, and prospects, were materially false and misleading and/or lacked a reasonable basis at all relevant times. When the true details entered the market, the lawsuit claims that investors suffered damages.

No Class Has Been Certified. Until a class is certified, you are not represented by counsel unless you retain one. You may select counsel of your choice. You may also remain an absent class member and do nothing at this point. An investor's ability to share in any potential future recovery is not dependent upon serving as lead plaintiff.
