For Immediate Release

Stewart Information Services Announces Plan to Create Single Class of Common Stock

HOUSTON, January 27, 2016 – Stewart Information Services Corporation (NYSE: STC) (“Stewart” or the “Company”) today proposed a plan to reclassify the Company’s common stock to eliminate its dual class structure. The proposed reclassification has been unanimously approved by the Company’s Board of Directors (the “Board”).

Under the terms of the proposed reclassification, holders of Class B Common Stock will exchange 1,050,012 shares of Class B Common Stock for 1,050,012 shares of Common Stock plus $12 million in cash in the aggregate. In support of the plan to reclassify, Stewart has entered into a definitive agreement providing for the proposed reclassification with the holders of the Class B Common Stock, which collectively own 1,050,012 shares of the Company’s Class B Common Stock.

Upon completion of this transaction, all outstanding shares of Stewart Common Stock will be entitled to one vote per share on all matters brought to the Company’s stockholders.

Thomas G. Apel, Chairman of the Board, said, “After a thorough analysis by the Board, we determined that this reclassification is in the best interests of the Company and all Stewart stockholders. We believe the proposal announced today will help to strengthen Stewart’s corporate governance, aligning voting rights with the economic interests of our stockholders.”

Matthew Morris, Chief Executive Officer, added “We look forward to continuing to pursue our strategic initiatives under a simplified structure that will provide a solid foundation for us to drive value creation and future growth.”

The Board believes the proposed reclassification will benefit stockholders by:

• Aligning the economic interests and voting rights of all stockholders;

• Eliminating the holders of the Class B Common Stock’s control rights and reducing the concentration of their voting power;

• Aligning the capital allocation interests of all stockholders;

• Moving in line with corporate governance best practices and being responsive to the 2015 stockholder proposal vote on this issue; and

• Broadening the appeal of Stewart’s stock to a larger base of investors.

The Company will be seeking stockholder approval of the reclassification as well as stockholder approval of certain amendments to the Company’s governing documents.

The completion of the proposed reclassification is subject to customary closing conditions, including required stockholder approvals from holders of Common Stock and the Class B Common Stock. The holders of the Class B Common Stock have agreed to vote all of their shares of Company stock in favor of the proposed reclassification. The proposed reclassification is expected to be completed in the second quarter of 2016.

The Company also entered into amended employment agreements with Malcolm Morris and Stewart Morris, Jr. which will become effective with shareholder approval of the reclassification. In addition, the Company entered into revised agreements related to certain existing insurance policies.

Additional details of the proposed reclassification and related matters, including the proposed amendments to the Company’s governing documents, the amended employment agreements and the settlement agreements will be described in the Company’s current report on Form 8-K with respect to the reclassification, which will be filed with the U.S. Securities and Exchange Commission.

Goldman, Sachs & Co. served as lead financial advisor to the Company and Skadden, Arps, Slate, Meagher & Flom LLP served as Stewart’s legal counsel.
