BioAmber Inc. (BIOA) Information Request Form

The Klein Law Firm announces that a class action complaint has been filed on behalf of shareholders of BioAmber Inc. (NYSE: BIOA) who purchased shares pursuant and/or traceable to BioAmber’s secondary public offering on or about January 23, 2017; and/or (2) on the open market from January 23, 2017 through March 16, 2017. The action, which was filed in the United States District Court for the Northern District of California, alleges that the Company violated federal securities laws.

The complaint alleges that throughout the Class Period BioAmber made materially false and/or misleading statements and/or failed to disclose that: (1) a large customer of BioAmber that was expected to purchase $2.8 million of succinic acid in Q4 2016 experienced a technical problem in its manufacturing facility and postponed the order to 2017; and (2) as a result, defendants’ statements about BioAmber’s business, operations, and prospects, were materially false and misleading and/or lacked a reasonable basis at all relevant times.

If you suffered a loss in BioAmber you have until May 17, 2017 to request that the Court appoint you as lead plaintiff. Your ability to share in any recovery doesn’t require that you serve as a lead plaintiff.

Keep Me Informed

The Klein Law Firm does not share your information with others. There is no cost or obligation. This submission does not create an attorney-client relationship. If we believe that you might be an appropriate lead plaintiff, we will contact you to discuss whether to establish an attorney-client relationship.

I am ready to join the action

This letter confirms that you have retained The Klein Law Firm to represent you as a named plaintiff in a shareholder action involving BioAmber Inc.

We agree to advance all expenses in the litigation, which means that you are not liable to pay any of the expenses of the lawsuit, whether attorneys' fees or costs. Regardless of the result, we will never ask you to directly pay for any attorneys' fees or costs. Should we obtain a favorable result, we may ask the court to award us compensation to be paid by the defendants or as a portion of any class benefit, but, again, we will never ask you to directly pay any of the costs of this litigation.

As the client you are entitled to direct the litigation in any way you deem proper, and may at any time order us to dismiss the case or opt-out. Should you choose to do so, we will never ask you to reimburse us directly for any legal fees or expenses. During the course of this litigation, we may employ and/or work with other law firms to prosecute your case.

We look forward to representing you and other BioAmber Inc. shareholders.

Sincerely,
