Item 8.01  Other Events

Conversion of class B common stock

On August 30, 2012, Sucampo Pharmaceuticals, Inc., or the Company, announced that its majority shareholder and only holder of its class B common stock, S&R Technology Holdings, LLC, or S&R, has converted all of its 26,191,050 issued and outstanding shares of the Company’s class B common stock into shares of the Company’s class A common stock. S&R held all of the Company’s class B common stock. Class B common stock holders were entitled to ten votes per share while class A common stock holders were entitled to one vote per share.

The Company’s articles of incorporation permit the holder of class B common stock to convert the shares of class B common stock into shares of class A common stock at any time and on a one-for-one basis. As a result of the conversion, there is now only a single class of the Company’s common stock outstanding, totaling 41,905,364 shares, each of which is entitled to one vote per share.

S&R trading plan

S&R adopted a stock trading plan in accordance with guidelines specified under Rule 10b5-1 of the Securities and Exchange Act of 1934 and the Company’s policies regarding stock transactions. In the future, they will begin selling a portion of their Company stock pursuant to the stock trading plan.

The pre-arranged stock trading plan was adopted in order to allow S&R to sell a portion of the Company’s stock over time as part of its long-term strategy to fund its businesses. The transactions under the plan will be disclosed publicly through Form 4 and Form 144 filings with the Securities and Exchange Commission. Using the plan, S&R can spread stock trades out over an extended period of time to reduce market impact. Because the plan was established well in advance of a trade, the plan also helps avoid concerns about whether S&R had material, non-public information when it made a decision to sell the Company’s stock.

S&R held approximately 26 million shares of Class B common stock, which represented approximately 63.0% of the Company’s common stock and approximately 94.4% of the voting power of the Company’s outstanding common stock. Under the terms of the Rule 10b5-1 trading plan, S&R intends to sell approximately 1 million shares. If S&R completes all the planned sales under the Rule 10b5-1 trading plan, S&R would continue to own approximately 25 million shares, which would represent approximately 60.6% of the Company’s outstanding common stock and voting power of the Company’s outstanding common stock (assuming no other sales and conversions of the Company’s common stock occur).

S&R is owned by the Company’s founders, Ryuji Ueno, M.D., Ph.D., Ph.D., the Company’s Chairman and CEO, and his wife, Sachiko Kuno, Ph.D., the Company’s Executive Advisor, International Business Development and a member of the Company’s Board of Directors.
