Tessera Updates Third Quarter 2009 Financial Guidance

Tessera Technologies, Inc. (Nasdaq:TSRA) today announced it is raising its third quarter 2009 Total Revenue guidance to range between $65.0 million and $66.0 million. Third quarter 2009 Micro-electronics Revenue, all of which will be royalty and license related, is now expected to range between $58.0 million and $59.0 million, driven by the improved second quarter performance in the company’s served markets. Prior guidance, announced on Aug. 4, 2009, was for third quarter Total Revenue to range between $60.0 million and $62.0 million and Micro-electronics Revenue to range between $54.0 million and $56.0 million.

The company now has greater visibility into its Imaging & Optics business, and as a result, is raising its third quarter 2009 Imaging & Optics Total Revenue to be approximately $7.0 million, of which approximately $4 million will be Royalties and License Fees. Prior guidance, given on Aug. 4, 2009, was Imaging & Optics Total Revenue of $6.0 million, of which approximately $3.0 million was Royalties and License Fees.

The company reiterated its guidance on its other third quarter 2009 items, which remain unchanged:

• Non-GAAP operating expenses are projected to range between $30.0 million and $31.0 million, excluding litigation expenses.
• Stock-based compensation is projected to be approximately $7.0 million.
• Amortization charges are expected to be approximately $3.0 million.

The company believes its effective tax rate for the full year 2009 will range between 45% and 46%.

Petition to Review Initial Determination in DRAM ITC Action

Tessera also announced that today it will file a Petition for Review of the Initial Determination issued on Aug. 28, 2009 by the Administrative Law Judge (ALJ) in the International Trade Commission (ITC) Investigation No. 337-TA-630 brought by Tessera against certain DRAM manufacturers and sellers (DRAM ITC action).

In the Initial Determination, the ALJ found Tessera’s asserted patents valid, but determined, among other things, that there was insufficient evidence to prove infringement. The Commissioners of the ITC recently held, unanimously, that similar evidence submitted by Tessera in Investigation No. 337-TA-605 (Wireless ITC action) was sufficient to prove infringement. Similar evidence also was accepted by the ITC in Investigation 337-TA-432, as well as last year in Tessera’s arbitration against Amkor Technology, Inc.

"We are focused on bringing the DRAM ITC action to a successful conclusion, and one that is consistent with prior court decisions regarding Tessera’s patents,” said Henry R. Nothhaft, president and CEO of Tessera. "We remain committed to preventing the unlicensed use of Tessera’s technology.”

According to the current schedule for the investigation, the Commission is expected to decide whether to review the Initial Determination no later than Nov. 2, 2009, and may request additional briefing at that time. If the Commission elects to review the Initial Determination, the Commission’s Final Determination accepting or rejecting a reversal is currently scheduled to be issued by Dec. 29, 2009. If, on the other hand, the Commission declines to review the Initial Determination, it would become final and Tessera would be permitted to appeal the decision to the Court of Appeals for the Federal Circuit.
