JUDGE The Hon. Raymond Joseph Dearie
CLASS PERIOD May 1, 2014 - December 5, 2018

Case Background:

This securities class action case was brought on behalf of those who purchased or otherwise acquired Tenaris American Depositary Shares between May 1, 2014 and December 5, 2018, inclusive (the “Class Period”).

The complaint alleged that throughout the Class Period, the defendants made false and/or misleading statements and/or failed to disclose that: (1) Tenaris’s Chief Executive Officer (“CEO”) and Chairman knew that one of his company’s executives paid cash to government officials from 2009 to 2012 to expedite compensation payments for the sale of Sidor; (2) this conduct would lead to the CEO being charged in a graft scheme, and subject Tenaris, its affiliates, and/or executives to heightened governmental scrutiny; and (3) as a result, Tenaris’s public statements were materially false and/or misleading at all relevant times. When the true details entered the market, the lawsuit claims that investors suffered damages.
