The Complaint alleges that Defendants made false and/or misleading statements and/or failed to disclose that: (1) the Company’s claimed distribution relationships with certain manufacturers of electric motorcycles and scooters were false; (2) the Company’s reported financial statements were grossly inflated by including gross profit margins which were unrealistic for similar companies in its industry; the Company paid $1.5 million to acquire a company that is non-existent; (4) the Company paid $20 million to purchase a company, but failed to disclose the related party nature of the transaction; (5) the Company paid $22 million to acquire another company without disclosing that it was a bailout of a related company; (6) the Company misrepresented that it owned a Company subsidiary when it did not, or the Company failed to disclose that it entered into a related party transaction with the Company’s Chairman and CEO which resulted in the owner of that subsidiary being the Chairman and CEO, and not ABAT; (7) the Company lacked adequate internal and financial controls; and (8) as a result of the foregoing, the Company’s statements were materially false and misleading at all relevant times.
