ITEM 2.02. Results of Operations and Financial Condition.

     On April 6, 2005, Monsanto Company issued a press release announcing its second quarter 2005 financial and operating results for the period ended February 28, 2005. This press release, as well as the second quarter fiscal year 2005 unaudited supplemental data, are furnished as Exhibits 99.1 and 99.2 hereto, respectively, and incorporated herein by reference.

     The press release furnished herewith uses the non-GAAP financial measure of earnings per share (“EPS”) on an ongoing basis. Our ongoing EPS financial measure excludes certain after-tax items that we do not consider part of ongoing operations, which are identified as such in the reconciliation. We believe that our ongoing EPS financial measure presented with these adjustments best reflects our ongoing performance and business operations during the periods presented and is more useful to investors for comparative purposes. In addition, management uses the ongoing EPS financial measure as a guide in its budgeting and long-range planning processes, and as a guide in determining incentive compensation. The presentation of EPS on an ongoing basis is intended to supplement investors’ understanding of our operating performance. This non-GAAP financial measure may not be comparable to similar measures used by other companies.

     We are furnishing the information contained in this report, including the Exhibits, pursuant to “Item 2.02 Results of Operations and Financial Condition” of Form 8-K promulgated by the Securities and Exchange Commission (“SEC”). This information shall not be deemed to be “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934 (“Exchange Act”) or otherwise subject to the liabilities of that section, unless we specifically incorporate it by reference in a document filed under the Securities Act of 1933 or the Exchange Act. By filing this report on Form 8-K and furnishing this information, we make no admission as to the materiality of any information in this report, including the Exhibits.
