SASKATOON, Saskatchewan — Potash Corp. of Saskatchewan Inc. and Agrium Inc. announced the mailing of the letters of transmittal and election forms in connection with the proposed merger of equals transaction to their respective registered shareholders.

Each company’s letter of transmittal and election form outlines the necessary documentation and information required to be sent to the depositary for the transaction, AST Trust Co., by a registered shareholder to receive the shares of the parent entity, Nutrien Ltd., to which they are entitled in exchange for their Agrium or PotashCorp common shares, as applicable, once the transaction is completed and, if eligible, to make an election in respect of their shares.

The letters of transmittal and election forms are for use by registered shareholders only. Beneficial shareholders who do not have their common shares of Agrium or PotashCorp registered in their name (rather, such shares are registered in the name of a broker or other intermediary) should contact their broker or other intermediary for instructions and assistance regarding receipt of any shares of Nutrien Ltd., to which they are entitled once the transaction is completed or, if eligible, to make an election in respect of their shares.

Agrium’s letter of transmittal and election form will be available on Agrium’s website at www.agrium.com, and PotashCorp’s letter of transmittal and election form will be available on PotashCorp’s website at www.potashcorp.com, and both letters of transmittal will be available on the merger website of Agrium and PotashCorp at www.worldclasscropinputsupplier.com. Copies of the applicable letter of transmittal and election form will also be available under Agrium’s and PotashCorp’s respective profiles on SEDAR at www.sedar.com and the Securities and Exchange Commission’s website at www.sec.gov. Additional copies of the letters of transmittal are also available by contacting Kingsdale Advisors at contactus@kingsdaleadvisors.com.

Any letter of transmittal and election form deposited with AST Trust Co. will be revocable up to the election deadline by written notice or by filing a later-dated letter of transmittal received by the depositary prior to the election deadline. A letter of transmittal and election form may not be withdrawn by a shareholder after the election deadline. Agrium and PotashCorp will announce the election deadline in a press release disseminated through nationally recognized wire services in Canada and the United States at least six business days prior to such deadline.

As previously announced, Agrium and PotashCorp have obtained the necessary shareholder and court approvals required to meet certain conditions to the completion of the transaction, but completion of the transaction remains conditional on the satisfaction of the remaining regulatory and other customary conditions.

Agrium and PotashCorp expect to close the transaction by the end of the fourth quarter of 2017. In the event that the transaction is not completed, any share certificates delivered to the depositary will be returned.
