Cypress Semiconductor Proposes to Acquire Ramtron International for $2.48 Per Share in Cash

Cypress Semiconductor Corporation (NASDAQ:CY) today announced that it has submitted a proposal to Ramtron International Corporation (NASDAQ:RMTR) to acquire all of its outstanding stock for $2.48 per share in cash. This offer represents a 37% premium to Ramtron’s closing stock price on June 11, 2012.

“We believe that our offer provides compelling value to Ramtron’s stockholders,” said T.J. Rodgers, President and Chief Executive Officer of Cypress. “Last year, we attempted to negotiate an acquisition of Ramtron, but our offer of $3.01 per share—which represented the same 37% premium to Ramtron’s then-current stock price as we are offering today—was summarily rejected. Soon thereafter, Ramtron sold almost 20% of its stock in a dilutive public offering at a net price of $1.79 per share.

“At this time, we call on Ramtron’s Board of Directors to act in the best interests of its stockholders by meeting with us to seriously discuss our compelling proposal. We believe that Cypress would benefit Ramtron’s customers, providing them with a more stable source of supply, greater research and development resources and better support from a much larger sales channel. We also believe the combination would provide Ramtron’s employees with more opportunity for long-term success as part of a larger, more global organization,” Rodgers continued.

In a letter sent to Ramtron today, Cypress stated that it would prefer a negotiated transaction. Cypress has engaged Greenhill & Co., LLC as financial advisor and Wilson Sonsini Goodrich & Rosati, Professional Corporation, as legal counsel.

The full text of the letter sent from Cypress to Ramtron today – along with letters sent on March 8, March 10 and April 11, 2011 – are set forth below:

Gentlemen:

I am writing to formally convey Cypress Semiconductor’s proposal to acquire Ramtron International Corporation for $2.48 per share in cash. This represents a premium of 37% over Ramtron’s closing price of $1.81 per share on June 11, 2012. We believe that this all-cash transaction, which has been unanimously approved by our Board of Directors, is compelling for Ramtron and its stockholders. Our proposal would deliver immediate, certain value to Ramtron’s stockholders that is far superior to what we believe that you can reasonably expect to achieve as a standalone company.

We believe that an acquisition can be completed expeditiously and are prepared to commence a cash tender offer with no financing or due diligence conditions. We have retained Greenhill & Co., LLC as our financial advisor and Wilson Sonsini Goodrich & Rosati, Professional Corporation, as our legal counsel. We are confident that a transaction would receive all necessary regulatory approvals, including antitrust clearances.

We hope to work with you on a negotiated basis to complete this transaction successfully, and are prepared to deliver a draft merger agreement and begin discussions immediately. I suggest that our respective financial and legal advisors meet at your earliest convenience to work toward the goal of announcement of a definitive agreement in the very near future.

It has been about two years since I first approached you about a possible transaction between our two companies and over a year since we delivered a formal proposal to acquire Ramtron. As you will recall, that proposal (at $3.01 per share) was for a 37% premium over your then-current stock price on March 8, 2011—the same premium we are offering today. Our offer made clear that we were prepared to commence due diligence immediately and would deliver a merger agreement with minimal closing conditions. We were deeply disappointed when, two weeks after we provided you with our offer, you and your Board of Directors responded that our offer was so low that it was not even worth your time to make a counter proposal.

Since then, a number of events have convinced us that your response did not reflect the best interests of your stockholders. First, soon after you rejected our offer, Ramtron sold almost 20% of its stock in a dilutive public offering at a net price of $1.79 per share, which I found extremely surprising in light of your comments regarding our offer and its 68% premium to that price. Second, since our offer Ramtron has had cumulative net losses of five cents per share. Third, your stockholders have been increasingly vocal about their desire for you to sell Ramtron. These factors, along with your history of rejecting out-of-hand our prior offer, have convinced us that we must make our offer public at this time so that your stockholders are aware of our efforts. I have attached copies of my prior letters to you to this letter.

Although we would prefer to proceed through a negotiated agreement, we are fully committed to this transaction, and will take the steps necessary to complete it. We believe that a transaction between our two companies would be well received by your stockholders, and we are committed to providing them with an opportunity to express their views on our proposal.

This letter does not represent or create any legally binding or enforceable obligations. No such obligations will be imposed on either party unless and until a definitive agreement is signed by both Cypress and Ramtron.

We request a response to our proposal by 5:00 p.m. Pacific Daylight Time on Tuesday, June 19, 2012. In light of the significance of this proposal to your stockholders and ours, as well as the potential for selective disclosure, we are publicly releasing the text of this letter.

Prior Correspondence Between Cypress and Ramtron

Text of the letter sent by Cypress to Ramtron on March 8, 2011

Dear Mr. Balzer:

The purpose of this letter is to propose the acquisition of Ramtron International Corporation by Cypress Semiconductor Corporation for $3.01 per share in cash, a 37% premium over Ramtron’s closing price of $2.20 on March 8, 2011 and a 32% premium over Ramtron’s 15-day, volume-weighted trading price of $2.28. This premium exceeds the 30% premium reported in comparable transactions in 2011—and is 2.4 times higher than the premium paid by Microchip Technology, Inc. in its acquisition of Silicon Storage Technology, Inc. in a 2010 transaction which is very similar to this proposed transaction. We have the cash on hand to complete this transaction in an expeditious manner.

We believe the transaction would be favorable not only to Ramtron’s shareholders, but also—and particularly—to Ramtron’s customers. Relative to Ramtron alone, the combined company would serve its customers with 1) a more stable source of supply, consisting of two non-volatile technologies from five wafer-fabrication plants (three from Cypress), 2) a lower manufacturing cost structure due to Cypress’s low wafer and assembly & test manufacturing costs, 3) shorter leadtimes due to our internal 45-day fab cycle time and 7-day assembly & test cycle times, 4) access to high density and higher performance products fabricated in Cypress’s advanced non-volatile technologies, 0.13-micron (in production in three fabs) and 0.65-micron (in production at UMC), 5) better support from Cypress’s 400-person Sales, Marketing and Field Applications Marketing teams, and 6) the lower overhead costs that would result from combining our Colorado Springs and other overhead operations.

In particular, we believe that as a combined company, we could bring immediate relief to Ramtron’s customers by rationing the scarce supply of FeRAMs to those customers who specifically need that technology, while immediately serving the needs of the rest of Ramtron’s other customers with Cypress’s high-quality, high-reliability, pin-compatible products, manufactured in our SONOS technology.

We would like to enter into a more substantial conversation with Ramtron regarding the details of this offer on an expedited schedule, so as to address the current market supply problem as quickly as possible. Of course, we will take the time to negotiate thoroughly and in good faith. We plan to make this offer public at the close of business on March 15, 2011.

Text of the letter sent by Cypress to Ramtron on March 10, 2011

Dear Mr. Balzer:

This letter documents the comments I made to you in our telephone conversation yesterday.

Here is the supplemental information that I provided:

• Cypress anticipates that there will be minimal due diligence (two weeks or less) required for a Ramtron-Cypress merger.
• We are prepared to sign a confidentiality agreement immediately as a condition of commencing due diligence.
• Cypress has studied the Hart-Scott-Rodino process and anticipates no regulatory problems.
• Cypress intends to accelerate all employee options and buy them out.
• Cypress is prepared to deliver a definitive merger agreement with minimal closing conditions and a fiduciary-duty out-clause for a superior proposal (subject to a reasonable breakup fee and Cypress’s right to match that superior offer).
• Cypress will work cooperatively with Ramtron to create a win-win deal for both companies.

Text of the letter sent by Cypress to Ramtron on April 11, 2011

Dear Bill:

I’m writing this letter to close the loop on our recent M&A discussions. On March 8, 2011, after a lot of careful deliberation, Cypress made an offer of acquisition to Ramtron with an embedded 37% premium to market. We felt—and still feel—that our offer would be attractive to your shareholders.

What we heard from you telephonically and in a letter dated March 22, 2011, was that you felt the offer was too low—so low, in fact, that it was not worth your while to make a counter proposal.

Although we do not agree with that position, we accept it and are officially withdrawing our offer to acquire Ramtron at this time. Please let me know if you would reconsider your position.

On another topic, I have enclosed a chart of Ramtron’s share price on which I have marked the dates of my acquisition proposal letter and your response to it. As you can see, there was a significant rise in Ramtron’s price after those events. While no one can say what drives the market up or down—and I am not trying to imply anything here—you might want to take a look at the security measures that were employed by Ramtron regarding this proposed transaction.
