Glancy Prongay & Murray LLP (“GPM”) announces that it has filed a class action lawsuit in the United States District Court for the Southern District of New York on behalf of a class (the “Class”) of purchasers of Aixtron SE (“Aixtron” or the “Company”) (Nasdaq: AIXG) securities between September 25, 2014 and December 9, 2015, inclusive (the “Class Period”).

If you are a member of the Class described above, you may move the Court no later than 60 days from the date of this notice to serve as lead plaintiff. Please contact Lesley Portnoy at 888-773-9224 or 310-201-9150, or at shareholders@glancylaw.com to discuss this matter.

On October 13, 2015, the Company issued a press release disclosing that it was revising its previously issued revenue guidance for the full year 2015 from 220 million – 250 million EUR down to 190 million - 200 million EUR due to “a postponement of shipments to a large Chinese customer which were planned for delivery in 2015.” The Company also announced that “[t]hese deliveries are now expected for 2016 depending on the progress of the ongoing milestone based qualification process.”

On this news the Company’s American Depository Receipts (“ADRs”) fell $0.84 per ADR, or 12.8%, to close on October 13, 2015, at $5.71 per ADR, on high trading volume.

Then, on December 9, 2015, the Company issued a press release announcing that it had “reached an agreement with its Chinese customer San’an Optoelectronics regarding a substantial reduction in the volume of AIX R6 MOCVD systems ordered from 50 to the three which have already been delivered.” The Company also disclosed that “the customer’s specific qualification requirements were not achieved.”

On this news the Company’s ADRs fell $3.05 per ADR, or 40%, over two trading days, to close at $4.49 per ADR on December 10, 2015, on unusually high trading volume.

The complaint charges Aixtron and certain of its officers with violations of the federal securities laws. Specifically, the complaint alleges that throughout the Class Period, defendants failed to disclose that: (1) that the AIX R6 MOCVD systems that were to be shipped to the Company’s large Chinese customer (San’an Optoelectronics) did not meet the customer’s specific qualification requirements; (2) that, as such, the Company’s agreement with San’an Optoelectronics to ship 50 of the Company’s AIX R6 MOCVD systems to San’an Optoelectronics was unlikely to be executed; (3) that the impending failure to execute the original agreement would have a substantial negative impact on the Company’s prospects; and (4) that, as a result of the foregoing, Defendants’ statements about AIXTRON’s business, operations, and prospects, were false and misleading and/or lacked a reasonable basis.

To be a member of the Class you need not take any action at this time; you may retain counsel of your choice or take no action and remain an absent member of the Class.
