ASX Announcement

IMDEX TO ENHANCE LEADING TECHNOLOGY STATUS WITH ACQUISITION OF IOGLOBAL

Imdex Limited (ASX: IMD) is pleased to announce the acquisition of ioGlobal Pty Ltd, ioAnalytics Pty Ltd and ioGlobal Solutions Inc (together ioGlobal). ioGlobal provides innovative cloud-based data management solutions for the mining, mineral exploration and oil and gas industries. It is anticipated that completion of the transaction and settlement will be effective 1 November 2012 and will be immediately earnings accretive for Imdex.

The $8 million acquisition will provide a range of significant growth opportunities. It will enhance Imdex’s product offering to drilling contractors, mining service providers and companies exploring and operating in the mineral and oil and gas industries.

Key acquisition benefits for Imdex

• Enhances product offering and customer profile

• A strategic, bolt-on acquisition that will be easily integrated

• Is consistent with Imdex’s growth strategy of being a provider of market-leading technology and solutions in the mining and oil & gas industries

• Will immediately generate additional and diversified revenue streams with excellent prospects for further growth

• Provides differentiated products and technology that are ready to be deployed on a global scale

• Enhances Imdex’s research and product development capabilities

• Complements Imdex’s commitment to product innovation, leadership and unrivalled technology.

Commenting on the strategic rationale underlying the acquisition, Imdex’s Managing Director, Bernie Ridgeway said, “ioGlobal is an excellent strategic fit for Imdex . The company’s products complement Imdex’s existing product offering, allowing us to expand our customer base, and offer excellent growth prospects within the mining and oil and gas sectors. At the same time,

ioGlobal will benefit from our sales and marketing expertise and access to a wider range of customers around the world.”

Mr. Ridgeway added that the bolt-on acquisition would extend and complement the growth cycle of Imdex’s Reflex downhole instrumentation by enhancing its value proposition.

“Our Reflex business enables customers to obtain positional data in an accurate, efficient and user-friendly way. ioGlobal ’ s technology, in time, will enhance this value proposition by providing positional data together with geophysical and geochemical information in a timely and user-friendly format – directly from the rig to the office.

“The combination of the two businesses and the potential growth synergies are very exciting. Geologists, management and operational personnel will be able to review crucial decision making data in an actionable format at the rig or off-site. In the future, such data will also be available in real-time. This translates into increased drilling time, improved efficiency, reduced operating costs, better decision making and increased safety for our customers.

“Our long-term growth strategy for Reflex centres on building its existing recurring revenue streams by providing leading technology that enables customers to obtain additional data and convert that data into actionable information. ioGlobal ’ s unique and highly differentiated technology will further enable the key elements of this strategy, and is ready to be deployed on a global scale leveraging Imdex’s international network,” added Mr. Ridgeway.

Acquisition consideration

The consideration for the acquisition will be satisfied by payment of $4.8 million in cash and $3.2 million in Imdex shares at an issue price equal to the volume-weighted average price of Imdex’s shares for the 10 days prior to settlement.

The $8 million consideration represents a multiple of just over 4 times forecast FY13 EBIT.
