Overview

OM Holdings Limited (OMH) is a vertically integrated manganese ore and ferroalloy company. According to its official website, the group is engaged in trading raw ores, smelting, and marketing of processed ferroalloys, and describes itself as having an established history of 30 years in the industry. It captures value across the entire process chain through operations in Australia, China, Japan, Malaysia, Singapore, and South Africa. OMH is listed on the Australian Securities Exchange (ASX) and was subsequently secondary listed on the Main Market of Bursa Malaysia on 22 June 2021, with all shares fully fungible between the two exchanges. Its latest major project is a greenfield smelter complex in Sarawak, Malaysia, which successfully commenced production in 2014. The company states that it is today one of the largest manganese and silicon smelters in Southeast Asia and seeks to be the main ferroalloy supply partner to major steel mills and other industries globally. Through its global trading network, it distributes products from an Asia-Pacific base to customers around the world. OMH's operations span three main areas: mining and exploration, smelting and sintering, and trading and marketing. It mines manganese ore from its wholly owned Bootu Creek mine in Australia and holds an effective 13% interest in the Tshipi Borwa mine in South Africa through a strategic partnership with a local partner. It also undertakes exploration projects to secure a long-term pipeline of material for its customers and smelters. Its smelters, located in Qinzhou (China) and Sarawak (Malaysia), produce manganese alloys including High Carbon Ferromanganese (HC FeMn) and Silicomanganese (SiMn), as well as silicon alloys such as Ferrosilicon (FeSi) and refined grades of FeSi. Manganese is described by the company as one of the most commonly used industrial metals in the world, with no known substitutes, and over 90% of ore mined is eventually consumed by the steel industry. Manganese alloys are essential for basic steelmaking, removing sulphur and oxygen from molten steel and improving properties such as hardness. Silicon alloys are used to deoxidize molten steel and have particular applications in electrical steels. OMH positions itself as a key supplier to the global steel industry and related sectors.

History

OM Holdings Limited describes itself as having an established history of 30 years in the manganese and ferroalloy industry. The company has grown into a vertically integrated group that spans mining and exploration, smelting and sintering, and trading and marketing of manganese ore and ferroalloys. A major development in the group's history was the construction of a greenfield smelter complex in Sarawak, Malaysia, which successfully commenced production in 2014. This facility became a cornerstone of OMH's smelting operations and helped establish the group as one of the largest manganese and silicon smelters in Southeast Asia. The group also operates a smelter in Qinzhou, China, producing manganese alloys. In mining, OMH owns the Bootu Creek manganese mine in Australia and holds an effective 13% interest in the Tshipi Borwa mine in South Africa through a strategic partnership with a local partner. These assets provide feedstock for its smelters and trading operations. On 22 June 2021, OM Holdings Limited was secondary listed on the Main Market of Bursa Malaysia, in addition to its existing listing on the Australian Securities Exchange (ASX). All shares are fully fungible between the ASX and Bursa Malaysia. The company maintains operations and a trading network across Australia, China, Japan, Malaysia, Singapore, and South Africa, distributing products from its Asia-Pacific base to customers worldwide.
