Jean-Luc Deltombe, ALT’s founder
Advanced Logic Technology S.A. (“ALT”), a high-tech geophysical instruments and software business in mining, geotechnical, water, and energy sectors, headquartered in Luxembourg and its U.S. subsidiary Mount Sopris Instruments Inc. (“MSI”) today announced that their shareholders have entered into a binding agreement to sell 100% of the shares of both companies to IMDEX Limited, an Australian listed group (ASX:IMD) and global leader in mining technology solutions.
Today’s announcement represents a major commitment to Luxembourg’s dynamic technology ecosystem, strengthening its role as a leading hub for innovation while acknowledging the nation’s legacy in iron ore and steel. IMDEX’s acquisition of ALT and MSI combines world-class borehole logging instruments and software with IMDEX’s integrated subsurface intelligence platform, creating the industry’s most advanced solution for exploration and development.
A strategic combination
The acquisition unites three market leaders with complementary strengths. ALT’s advanced borehole imaging instruments and industry-standard WellCAD software, MSI’s rugged geophysical logging systems, and IMDEX’s global platform will form a unified ecosystem delivering richer data insights and improved decision-making.
Together the collaboration accelerates innovation, expands global reach for Luxembourg-based ALT and U.S.-based MSI, and enhances value for clients across mining, geotechnical, water and energy sectors. IMDEX’s investment underscores Luxembourg’s role in advanced technology and innovation, reinforcing ALT’s legacy of pioneering solutions for over three decades.
Shareholder perspective
Jean-Luc Deltombe, ALT’s founder, commented: “For over 30 years, ALT has delivered precision, reliability, and innovation in borehole imaging and downhole measurement. IMDEX’s acquisition is a proud moment for me, my fellow shareholder Annick Henriette, our management, and all our staff. IMDEX’s global platform and technical depth provide ALT and MSI the scale to accelerate innovation and deliver even greater value across mining, geotechnical, water, and energy sectors.”
The transaction also marks the successful completion of a transition plan, including the appointment of new management and the phased exit of ALT’s founding shareholder. Jean-Luc stepped back from daily business activity in 2023 while co-shareholder Annick Henriette retired earlier this year. These changes ensure continuity and stability for the company, its employees, clients and business partners.
Looking ahead
IMDEX’s investment is a huge vote of confidence in ALT and MSI’s business and underpins a commitment to customers across the world. The same trusted teams will continue to operate from Luxembourg and Denver, now backed with the resources and capabilities of a global leader. The transaction is subject to foreign direct investment approval in Luxembourg and customary closing conditions, with completion envisaged in early 2026.
