According to the Complaint, Rudolph Technologies, Inc. ("Rudolph") is a leader in the design, development, manufacture, and support of defect inspection, lithography, process control metrology, and process control software used by semiconductor and advanced packaging device manufacturers worldwide.

This action stems from a proposed transaction announced on June 24, 2019, pursuant to which Rudolph will be acquired by Nanometrics Incorporated.

On June 23, 2019, Rudolph’s Board of Directors caused the Company to enter into an agreement and plan of merger with Nanometrics. Pursuant to the terms of the Merger Agreement, Rudolph’s stockholders will receive 0.8042 shares of Parent common stock for each share of Rudolph common stock they own.

On August 15, 2019, Defendants filed a Form S-4 Registration Statement with the United States Securities and Exchange Commission in connection with the Proposed Transaction.

The Complaint alleges that the Registration Statement omits material information with respect to the Proposed Transaction, which renders the Registration Statement false and misleading.

This case was voluntarily dismissed on October 15, 2019.
