Item 7.01. Regulation FD Disclosure.

Caterpillar Inc. (“Caterpillar”) is furnishing supplemental information concerning deliveries to users for retail sales of machines and sales of power systems (including reciprocating and turbine engines and locomotives) to retail users and Original Equipment Manufacturers (“OEMs”). In addition, we are providing information relating to the distribution of machinery and engines by major end use. Caterpillar sells the majority of its machinery and power systems to independently owned and operated dealers and OEMs to meet the demands of their customers, the end users.  Due to time delays between Caterpillar’s sales to dealers and dealers’ deliveries to end users, Caterpillar believes this information may help readers better understand Caterpillar’s business and the industries it serves.  This information is primarily based on unaudited reports provided by Caterpillar’s independent dealers which are not subject to Caterpillar’s internal controls over financial reporting.  This information is furnished under this Report with the Securities and Exchange Commission. Caterpillar does not undertake to update or adjust prior period information.

To the extent possible, Caterpillar includes acquisitions in its retail statistics about one calendar year after an acquisition closes in order to have a prior period comparison.  In August 2010, Caterpillar acquired Electro-Motive Diesel (“EMD”).  Therefore, beginning with January 2012 statistics, EMD’s sales of engines and locomotives will be included in the new “Transportation” sector.  The Transportation sector includes power systems for marine, rail and on-highway applications and locomotives.  In order to provide a consistent comparison for readers, Caterpillar intends to provide statistics for the former “Marine” sector for the first quarter of 2012.  For the 3-month rolling period ending March 2012 compared with the same months of the prior year, Marine was down 6%.
