Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

On March 9, 2015, Ingredion Incorporated (“Ingredion”) received notification from the Federal Trade Commission (“FTC”) that the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, relating to the previously announced potential acquisition of Penford Corporation (the “Merger”) by Ingredion had been terminated.

The Merger was approved by Penford’s shareholders on January 29, 2015. FTC clearance is the final U.S. regulatory approval required and Ingredion expects to complete the Merger in March 2015, subject to the satisfaction or waiver of the remaining closing conditions relating to the Merger.

Forward-Looking Statements

This current report on Form 8-K contains or may contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. The Company intends these forward-looking statements to be covered by the safe harbor provisions for such statements. Forward-looking statements include, among other things, any statements regarding the closing of the acquisition of Penford Corporation. These statements can sometimes be identified by the use of forward looking words such as “may,” “will,” “should,” “anticipate,” “assume”, “believe,” “plan,” “project,” “estimate,” “expect,” “intend,” “continue,” “pro forma,” “forecast,” “outlook” or other similar expressions or the negative thereof. All statements other than statements of historical facts in this report or referred to in this report are “forward-looking statements.”

These statements are based on current circumstances or expectations, but are subject to certain inherent risks and uncertainties, many of which are difficult to predict and are beyond our control. Although we believe our expectations reflected in these forward-looking statements are based on reasonable assumptions, stockholders are cautioned that no assurance can be given that our expectations will prove correct. Actual results and developments may differ materially from the expectations expressed in or implied by these statements, based on various factors. Factors relating to the pending acquisition of Penford Corporation that could cause actual results and developments to differ from expectations include: the pending acquisition may not be consummated in a timely manner or at all due to failure to satisfy any remaining conditions to closing or other factors; the anticipated benefits of the pending acquisition, including synergies, may not be realized; and the integration of Penford’s operations with those of Ingredion may be materially delayed or may be more costly or difficult than expected. Our forward-looking statements speak only as of the date on which they are made and we do not undertake any obligation to update any forward-looking statement to reflect events or circumstances after the date of the statement as a result of new information or future events or developments. If we do update or correct one or more of these statements, investors and others should not conclude that we will make additional updates or corrections. For a further description of these and other risks, see “Risk Factors” included in our Annual Report on Form 10-K for the year ended December 31, 2014 and subsequent reports on Forms 10-Q and 8-K.
