Item 8.01 – Other Events.
On August 30, 2022, Sesen Bio, Inc. (the “Company”) announced that it has filed the Stipulation of Settlement to settle the previously disclosed consolidated derivative lawsuits captioned In re Sesen Bio, Inc. Derivative Litigation, Lead Case No. 1:21-cv-11538, the derivative lawsuit captioned Tang v. Sesen Bio, Inc., et al., Case No. 2281-cv-00135 and other potential related derivative claims (collectively, the “Derivative Litigation”) against the Company’s board of directors and certain of its officers, with the Company named as a nominal defendant. As disclosed on August 17, 2022 in a Current Report on Form 8-K, the Company has also filed a Stipulation and Agreement of Settlement to settle the previously disclosed securities litigation (the “Securities Litigation”).
In May 2022, the Company initiated a process to review potential strategic alternatives with the goal of maximizing shareholder value. The Company believes that the settlements, if approved, have the potential to enable a favorable strategic transaction by increasing the range and attractiveness of strategic alternatives that the Company is able to consider. The Company, the Company’s Board of Directors and the individual defendants continue to deny all allegations of wrongdoing. The decision to settle the Derivative Litigation and the Securities Litigation is driven by the desire to avoid the uncertainty, risk, expense and distraction of protracted litigation.
The Stipulation of Settlement related to the Derivative Litigation confirms that the Company previously adopted certain corporate governance enhancements in response to, among other things, the filing of the Derivative Litigation, and that, subject to final court approval, the Company will adopt additional corporate governance enhancements. The Stipulation of Settlement also provides for a $630,000 payment for plaintiffs’ attorneys fees due to the benefits the corporate governance enhancements are intended to provide to the Company. The payment of plaintiffs’ attorneys fees is being funded by the Company and its insurance carriers. The Stipulation of Settlement related to the Derivative Litigation is filed as Exhibit 99.1 hereto and is incorporated herein by reference. The settlement of the Derivative Litigation and the Securities Litigation are subject to final court approval.
CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS:
This Current Report on Form 8-K contains forward-looking statements, including, but not limited to, statements regarding the Company’s plans to review potential strategic alternatives with the goal of maximizing shareholder value and the Company’s belief that the settlements, if approved, have the potential to enable a favorable strategic transaction by increasing the range and attractiveness of strategic alternatives that the Company is able to consider, which are based on the Company’s current expectations and inherently involve significant risks and uncertainties. The Company’s actual results and the timing of events could differ materially from those anticipated in such forward-looking statements as a result of these risks and uncertainties, including the risk that the respective courts may not approve the settlements, and the risk that the Company may not be successful in identifying one or more strategic alternatives or ultimately pursuing a strategic alternative that delivers the anticipated benefits or enhances shareholder value, among other risks and uncertainties. A further description of the risks and uncertainties relating to the business of the Company is contained in the Company’s most recent annual report on Form 10-K and the Company’s quarterly reports on Form 10-Q, as well as any amendments thereto reflected in subsequent filings with the Securities and Exchange Commission. The Company undertakes no duty or obligation to update any forward-looking statements contained in this report as a result of new information, future events or changes in its expectations.
