Item 2.02  Results of Operations and Financial Condition

On August 6, 2018, Cabot Corporation (the “Company”) issued a press release announcing its financial results for its fiscal quarter ended June 30, 2018 and furnished the press release with a Current Report on Form 8-K (the “Original 8-K”).  The press release contained an error in the discussion of cash performance, and stated that net working capital in the quarter increased by $72 million.  The correct amount was $58 million.  The correct statement of our cash flows from operating activities is as follows: “During the quarter ended June 30, 2018, our cash flows from operating activities were $62 million, which was net of a $58 million increase in net working capital.”

For ease of reference, we are filing this 8-K/A to amend the Company’s Original 8-K to correct this error in the discussion of our cash performance, and to make the related change in the Condensed Consolidated Statements of Cash Flows and the Reconciliation of Discretionary Free Cash Flow.

The information furnished with this Item 2.02 shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference into any other filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such a filing.
