KEY FACTS

 

   

A definitive agreement for the acquisition of Catalyst Semiconductor by ON Semiconductor was announced today

(July 17).

 


   

This will be an all-stock transaction with an equity value of approximately $115 million and an enterprise value of approximately $85 million.

 

   

The companies expect the transaction to close in the fourth quarter of 2008.

 

   

This agreement has been approved by both boards of directors.

 

   

Catalyst Semiconductor shareholders will need to vote on this agreement. (A Catalyst shareholder meeting will most likely take place during the fourth quarter.)

 

   

ON Semiconductor shareholders do not need to vote on this agreement. SEC regulations do not require a vote.

“ALL STOCK” TRANSACTION

 

   

Under the terms of the agreement, Catalyst Semiconductor shareholders will receive 0.706 shares of ON Semiconductor common stock for each share of Catalyst Semiconductor common stock they own.

 

   

Upon completion of the transaction, ON Semiconductor will issue approximately 13 million shares of common stock on a fully diluted basis to complete the transaction or approximately 3 percent of ON Semiconductor’s fully diluted shares outstanding.

 

   

Shares of the combined company will trade on the NASDAQ Global Exchange under the symbol “ONNN.”

EMPLOYEES

 

   

Catalyst Semiconductor currently employees approximately 250 people. The majority of these employees are located in Santa Clara, California; Bucharest, Romania; and Thailand. They also have employees in a number of other countries.

 

   

ON Semiconductor expects to offer substantially all Catalyst employees positions. (No layoffs are currently planned as a result of the announced acquisition.)

 

   

Gelu Voicu, Catalyst’s CEO, will be joining the ON Semiconductor team.

BUSINESS OPERATIONS

 

   

Once this deal is completed, Catalyst’s customers, distributors, sales reps, vendors and suppliers can expect business to continue virtually unchanged for the foreseeable future.

FAQs

Why is ON Semiconductor buying Catalyst Semiconductor?

 

   

The acquisition of Catalyst Semiconductor will add to ON Semiconductor’s high gross margin analog and mixed signal products offerings for the digital consumer and wireless end-markets.


   

Catalyst’s EEPROM technology will strengthen ON Semiconductor’s ASIC and power products capabilities expanding ON Semiconductor’s ability to more comprehensively address its customers’ needs.

 

   

Catalyst’s EEPROM (memory) product segment provides a new total available market (TAM) opportunity for ON Semiconductor of approximately $800 million to $1 billion.

 

   

With the combination of ON Semiconductor’s global footprint, effective channels of distribution, and top-tier customer relationships, ON Semiconductor expects to be able to support a broader and deeper penetration of Catalyst’s overall product portfolio.

 

   

Catalyst has a long history of developing proprietary Intellectual Property (IP) and proven designs.

 

   

Catalyst Semiconductor’s strong portfolio offering should also benefit from ON Semiconductor’s integrated manufacturing capabilities. The acquisition also further enhances the utilization of the Gresham facility.

 

   

To compete successfully in today’s global marketplace, size and scale are important. ON Semiconductor provides Catalyst with:

  o Enhanced scale
  o Deeper customer relationships and sales channels
  o Integrated manufacturing capabilities
  o An expanded addressable market

Catalyst has a “fabless” business model. Does ON Semiconductor plan to bring some or all manufacturing in-house?

 

   

Catalyst’s strategy has always been to be a fabless supplier. This has enabled Catalyst to select the best fab location and process for each of our product families. Moving forward, we will maintain the philosophy of selecting the best fab and process for the new products we develop.

How does Catalyst’s sales model align with ON Semiconductor’s?

 

   

The two companies have complimentary customers, supply chains, manufacturing technologies and sales channels.

 

   

Much like ON Semiconductor, a large percent of Catalyst’s sales are made through distribution channels. The remainder of Catalyst’s sales are done via sales reps and the internal sales team.

 

   

Catalyst’s customers will benefit from the support of ON Semiconductor award winning channel sales and supply chain operations. Because ON Semiconductor and Catalyst utilize many of the same distributors, we can build on these well-established relationships.

What products and markets does Catalyst sell into?

 

   

Catalyst’s portfolio includes Digitally Programmable Potentiometers [DPP™], white and color LED drivers, DC/DC converters, voltage supervisors, I/O expanders, serial and parallel.


 

EEPROMs, Flash memories, and NVRAMs. Typical applications for our ICs include LCD displays, cellular phones, automotive illumination and instrumentation, optical networks, wireless LANs, network cards, DIMM modules, printers, digital satellite box receivers and set-top boxes.

How long has Catalyst been in business?

 

   

Catalyst has a history of producing high quality products for more than 20 years.
