Forward Looking Statements &Non-GAAP Measures

The following presentation contains forward-looking information based on the current expectations of Terex Corporation. Because forward-looking statements involve risks and uncertainties, actual results could differ materially. Such risks and uncertainties, many of which are beyond the control of Terex, include among others: our business is highly cyclical and weak general economic conditions may affect the sales of its products and its financial results; our business is sensitive to fluctuations in interest rates and government spending; the ability to successfully integrate acquired businesses; the retention of key management personnel; our businesses are very competitive and may be affected by pricing, product initiatives and other actions taken by competitors; the effects of changes in laws and regulations; our business is international in nature and is subject to changes in exchange rates between currencies, as well as international politics; our continued access to capital and ability to obtain parts and components from suppliers on a timely basis at competitive prices; the financial condition of suppliers and customers, and their continued access to capital; our ability to timely manufacture and deliver products to customers; possible work stoppages and other labor matters; our debt outstanding and the need to comply with restrictive covenants contained in our debt agreements; our ability to maintain adequate disclosure controls and procedures, maintain adequate internal controls over financial reporting and file its periodic reports with the SEC on a timely basis; the previously announced investigations by the SEC and the Department of Justice; compliance with applicable environmental laws and regulations; product liability claims and other liabilities arising out of our business; and other factors, risks, uncertainties more specifically set forth in our public filings with the SEC. Actual events or the actual future results of Terex may differ materially from any forward looking statement due to those and other risks, uncertainties and significant factors. The forward-looking statements speak only as of the date of this presentation. Terex expressly disclaims any obligation or undertaking to release publicly any updates or revisions to any forward-looking statement included in this presentation to reflect any changes in expectations with regard thereto or any changes in events, conditions, or circumstances on which any such statement is based.

Non-GAAP Measures: Terex from time to time refers to various non-GAAP (generally accepted accounting principles) financial measures in this presentation.

World Market – Mining Truck Sales by Class

Terex is well positioned for market needs

10

Hydraulic Excavators

• Superior mobility as compared to an electric rope shovel

• Leadership position in electric drive

• Well suited for rapid mine start-ups

• Largest hydraulic excavator with bucket size up to 50 cubic meters

• Hydraulic excavators beginning to replace electric rope shovels

Higher mobility provides greater flexibility in mining operations

11

Full Range of AC Drive Hauling Solutions

• Leadership position in high efficiency AC drive trucks

• Higher up time

• Lower operating cost

• Higher payload

• Better operating performance compared to mechanical drive in

• starting torque

• travel speed

• braking

• 120 ton to industry leading 400 ton capacity AC electric drive trucks

Lower total cost of ownership and superior performance

12

Mobile Materials Processing

• Portable and manoeuvrable for smaller spaces and between job sites

• Minimizes need for transportation of aggregate

• Low cost solution for meeting re-use/recycling laws

• Attractive for larger operators in times of market uncertainty due to mobility between sites or ability to use for a limited period of time and then sell

Mobility and flexibility is highly desired by customers

13

Outlook

• Underlying drivers for global mining and aggregate demand are intact and are likely to continue

Developing markets driving increased global demand Demand driving increased investment and activityExpanding need for equipment

• Competition will intensify, but we are well positioned to capitalize on strong global markets

Strong product franchisesQuality of global distributionImproving aftermarket capabilities
