Carmeuse announced this week that it has acquired a controlling stake in Chile-based Cbb. It said that the transaction strengthened its presence in South America, building on its existing operations in Colombia and Brazil. The move marks a diversification for the Belgium-based lime company. Cbb, formerly Cementos Bío Bío, is a vertically integrated heavy building materials producer with cement and concrete plants, in addition to limestone mines and plants.
The transaction sees Carmeuse take over a 97% share of Cbb for around US$490m. The deal was made public in early August 2025. A public tender offer, as part of the acquisition process, then completed on 11 September 2025. The settlement date, when the share ownership changes and the payment is made, will take place on 23 September 2025. The takeover was able to proceed once the main family-based shareholders of Cbb, who owned around 65%, agreed to the deal. Peru-based cement company Yura, which owned around another 20%, also consented. It sold its share for around US$100m.
The takeover of Cbb has been a while in the making and has involved different parties. It first became apparent to the public in late 2024 that Peru-based Grupo Gloria, the owner of Yura, had launched a bid to buy an additional 20% share. The board of Cbb rejected the offer, which appraised the full company at just under US$400m, as undervalued. Around the same time, Cbb revealed that US-based Mississippi Lime Company (MLC) had made its own takeover bid in May 2024 for around US$500m. However, MLC then withdrew its offer. Both Yura and MLC reportedly made their approaches in conjunction with some of the local family-based major shareholders. Also, note the interest by another lime company in Cbb.
Jump forward nine months and the deal appears done. Yet, as mentioned above, Carmeuse is buying more than just a lime producer. Cbb operates three integrated cement plants and one grinding plant in Chile. It also runs a grinding plant at Matarani, in the south of Peru. Global Cement Directory data suggests that the plants in Chile have a cement production capacity of over 3Mt/yr. This places the clinker capacity cost at around US$160/t. However, the capacity utilisation rate is likely to be low at present given that the company reported cement despatches of 1.2Mt in 2024. In addition, Cbb runs 27 ready-mixed concrete plants, two lime plants and three limestone mines in Chile. In Argentina it operates a lime plant and a lime mine. The company reported lime despatches of 0.83Mt in 2024.
Cbb recorded sales revenue of US$204m for cement and US$174m for lime. Pertinently, it noted a profit of US$2.26m for the cement division but one of US$35m for the lime one. Although, to be fair, sales revenue and profit grew year-on-year for both divisions. For the cement sector, the company said that the industry had experienced one of the “most severe crises in 2024 in the last 30 years.” It reported a decline in new construction projects due to rising material costs, higher credit requirements, low business confidence and a poor general economy. Ratings agency Humphreys noted, in a report on the cement sector in Chile in December 2024, that Cbb had improved its earnings margin in recent years due to the performance of its lime division.
Carmeuse’s acquisition of Cbb is a major change for the cement sector in Chile following declining cement despatches since 2021. From here one question is whether Carmeuse wants to run a cement and concrete business in Chile. The current state of the cement market in Chile, Carmeuse’s expertise in lime and the profitability of Cbb’s lime division, are three reasons why it might decide to divest this part of the business at a later date. On the other hand, Carmeuse’s expertise running rotary lime kilns could certainly feed into a new cement division if it chose to. MLC’s earlier interest in Cbb and a lack of many other cement companies being linked to the divestment also suggest that the focus has firmly been on the lime side of Cbb’s business. The one cement company that was interested, Yura, has links to lime too. Sister company Cal & Cemento Sur runs a lime plant in Puno Region in Peru, with US$100m plans for a new lime plant in Lima also in the works. The future of the cement division of Cbb is likely to be watched closely.
