The Internet allows unprecedented opportunity for communication between Christians from different theological traditions. The results have not been pretty. Comment threads are the Devil's playground and blogs his amusement park. And even if we exclude online media, theological bickering between Christians is and has been pervasive. Regrettably, Christians who hold to the Reformed confessions are often viewed by other Christians outside our tradition as some of the least winsome members of what we call the communion of the saints.
The command to love has been lost by us, if not lost on us. But how can the theologically astute love their equally theologically astute brothers and sisters across contentious theological and denominational lines? The solution is in the life, death, and love-commanding witness of Jesus.
Consider Jesus' silence for a moment. As a weekly synagogue attender and itinerant preacher, Jesus was bombarded with heterodoxy, moralistic deism, theological mush, progressive nationalism, and spiritual immaturity. And I'm only speaking of what came from devout Jews. Jesus was able and entitled to rebuke the slightest theological imprecision among the faithful at any moment. But when we consider how much theological correction He could have done, His silence speaks more than His teaching. Jesus did not draw attention to every theological imprecision that He heard. He loved sinners and was patient with their theological inaccuracy and spiritual immaturity.

Poland: CRH-subsidiary Cement Ożarów has appointed Mariusz Adamek as its chief operating officer. He was previously the company's Industrial Director. Prior to this he was the managing director of Geocycle in Poland. Earlier in his career he worked for Lafarge with placement in Poland and Egypt.
Holcim to delist from Euronext Paris
France/Switzerland: Holcim plans to delist all shares from the Euronext Paris exchange. Shares in the Switzerland-based group will continue to trade on the SIX Swiss Exchange. The cement producer explained its decision in terms of its need to simplify its trading structure. It expects thereby to further reduce its administrative costs and requirements.
Holcim pays the price
Doing deals with terrorists has a price: US$778m. The US Department of Justice (DOJ) revealed this week that it had fined Lafarge for its conduct in Syria between 2013 and 2014. In addition Lafarge and its subsidiary Lafarge Cement Syria (LCS) have pleaded guilty to one count of conspiring to provide material support to designated foreign terrorist organisations in Syria. It is uncertain how exactly the fine will be paid but it is worth noting that successor company Holcim reported net sales of nearly US$27bn in 2021. The fine represents nearly 2% of this.
A reasonable amount of new detail can be found on the DOJ website. LCS was essentially dealing with the Islamic State of Iraq and al-Sham (ISIS) and the al-Nusrah Front (ANF) as they would a local government in relation to the running of the Jalabiyeh cement plant. As a reminder, both of these groups were defined as terrorist organisations by the US government at the time. The relationship apparently started as monthly payments to local armed groups, including ISIS and ANF, to allow movement through checkpoints. This later progressed to a de-facto tax based on cement sales. However, it became worse when LCS started asking ISIS to block or tax imports of cement from Turkey-based competitors into northern Syria as part of a revenue-sharing agreement. Effectively LCS was fixing the price of cement in a war zone by collaborating with terrorists. In the end LCS, the intermediaries and the terrorist groups made around US$80m whilst they were working together.
Holcim's interpretation of the ruling was keen to point out that the conduct in Syria was recognised by the DOJ as not involving Holcim in any way. The DOJ did agree that Lafarge's executives didn't disclose their activities in Syria to its successor company Holcim either before or after the merger in 2015. However, it pointed out that Holcim had not carried out due diligence of LCS's operations in Syria. It added that, "Lafarge, LCS and the successor company also did not self-report the conduct or fully cooperate in the investigation."
Despite this, other information that Holcim also highlighted was that the US authorities were now happy that effective compliance and risk management controls were in place to prevent anything similar happening again. Crucially, it said that the DOJ didn't think that an independent compliance monitor was required. It pointed out that none of the conduct involved Lafarge's operations or employees in the US and that none of the Lafarge executives were working for Holcim or any associated company. Finally, the group wanted to report that the DOJ found that none of the former Lafarge executives involved shared any of the "methods, goals or ideologies" of the terrorist groups operating in area at the time.
The immediate reaction from all of this is what happens to the ongoing legal case in France, also about Lafarge's conduct in Syria? In mid-May 2022 the Court of Appeals confirmed a charge of complicity in crimes against humanity against Lafarge. The company then reportedly started the appeal process at the Supreme Court. Other charges, including financing terrorism, endangering life and violating an embargo, were lodged earlier in the legal process. The US is generally seen as being the leading prosecutor of international corporate crime but if the French legal system also issued a fine to Lafarge on the same scale things could become difficult for Holcim. The other complication for the French legal case is that the national intelligence services allegedly used Lafarge's links with the Syrian terror groups to acquire information but they did not warn the company that it was committing a crime.
Holcim is a different company from what it was when LafargeHolcim formed in 2015. It is being run by a new chief executive officer who came in from another company well after the merger and is diversifying away from the trio of cement, concrete and aggregates with the addition of a fourth business area of light building materials. Alongside this the group has been selling off businesses in the developing world and focusing on Europe and North America. Yet it is still being defined by the criminal actions of a company it absorbed seven years ago and the behaviour of staff long gone. Those actions have been investigated and punishment delivered. More may be coming.

Lafarge Cement Syria fined US$778m for terror support
Syria/US: A US court has found Lafarge Cement Syria guilty of conspiring to provide material support to the terrorist organisations al-Nusrah Front (ANF) and ISIS in Northern Syria during 2013 and 2014. Lafarge Cement Syria and its parent company, France-based Lafarge, agreed in 2011 to pay the terrorists for Lafarge Cement Syria employees' 'protection' and the continuation of the Jalabiyeh cement plant's operations, as well as to gain an economic advantage over other Syrian competitors. During the duration of the agreement, Lafarge Cement Syria recorded US$70.3m in sales. Coalition forces fighting against ANF and ISIS damaged the plant in an airstrike 'to reduce the facility's military usefulness' on 16 October 2019.
The court ordered Lafarge Cement Syria to pay criminal fines and forfeiture totaling US$778m.

Court confirms Lafarge charge of complicity in crimes against humanity
France: The Court of Appeals has confirmed a charge of complicity in crimes against humanity against Lafarge, now part of Holcim. The company will now appeal the decision to the Supreme Court. The confirmation establishes the scope of the charges that Lafarge will face, if unsuccessful in its appeal.
Global Cement previously reported that Lafarge allegedly made indirect payments to terror organisation ISIS between 2011 and 2014 in order to keep its Jalabiya cement plant operational during the Syrian Civil War. French prosecutors opened an investigation into the company's activities in the country in June 2017, leading to its indictment for complicity in crimes against humanity on 28 June 2018.
Adani Group and other mega-deals in the cement industry
Holcim agreed to sell its Indian assets to Adani Group this week for US$6.37bn. These include Holcim's stakes in its local subsidiaries Ambuja Cement and ACC. The deal, if approved by the local competition body, should complete in the second half of 2022. This is one of the larger sales of cement company assets over the last decade. Adani Group, an Indian-based conglomerate with businesses across energy, transport and more, is now poised to become the second largest cement producer in India.
Global Cement Weekly previously covered a potential sale of Ambuja Cement and ACC in April 2022 when the story that Holcim was looking for a buyer first emerged in the Indian press. At the time local press speculated that the sale could generate as much as US$15bn for Holcim. So it is interesting to see that a figure of US$6.37bn has been agreed upon instead, less than half of the speculative figure. Roughly, as ever, this places a value of a little below US$100/t of cement production capacity. This seems like a relatively low pricing for these plants by international standards over the last decade. However, this doesn't take into account many factors such as, for example, the condition of the plants, Holcim's desire to change its business, the ease of selling up in India all in one go, other non-cement assets and so on. For Adani Group though, buying into heavy building materials production in a large market like India clearly seemed attractive. It is also worth noting that, similar to other cement sector acquisitions recently, here again is a buyer with a background in another carbon-heavy industry buying into another heavy emitter.

Table 1 above provides some historical context to Adani Group's agreed acquisition by comparing it to other large completed deals in the cement sector over the last decade. Don't forget that it is only looking at this from the cement sector. This list excludes changes in ownership in the Chinese cement companies in this period because, generally, there has been a government-driven consolidation in the industry through mergers rather than large-scale acquisitions. So, for example, the world's current biggest cement producer CNBM had a reported production capacity of 350Mt/yr in 2012 and this rose to 514Mt/yr in 2020 as it absorbed other state-owned companies. The big merger it underwent during this time was with China National Materials (Sinoma) in 2018, primarily an engineering company that also produced cement.
The most obvious trend in Table 1 is the journey of Lafarge and Holcim from their merger in 2015 and the gradual realignment of the business subsequently. During this time the company has sold up in large markets outside of its core regions in Europe and North America. Latterly, it has also started to diversify away from heavy into lightweight building materials. One notable 'nearly happened' was LafargeHolcim's attempt to sell its business in the Philippines to San Miguel Corporation for US$2.15bn in 2019. That deal collapsed when the Philippines Competition Authority failed to approve it within a year of its proposal. CRH enlarged itself from assets sold during the creation of LafargeHolcim and then picked up Ash Grove in the US in 2018. CRH's head Albert Manifold memorably said in 2018 that his company was focusing on markets in developed countries and CRH's large-scale acquisitions have largely followed this.
As for the others, HeidelbergCement's purchase of Italcementi in 2016 almost appeared as a riposte to the formation of LafargeHolcim, albeit on a slightly smaller scale. It confirmed HeidelbergCement's place as the world's second largest non-Chinese cement producer. It is also one of the minority of truly multinational acquisitions on this list. Unlike LafargeHolcim and now Holcim though, HeidelbergCement hasn't exhibited a desire to downsize or diversify at quite the same speed. UltraTech Cement's acquisition of Jaiprakash Associates in 2017 confirmed its place as the largest Indian producer. That deal was publicly one of the longer lasting one as it originally started out in at least 2014 on a smaller scale and was later slowed down by the Mines and Minerals (Development and Regulation) (MMDR) Amendment Act. Smikon's purchase of Eurocement in 2021 almost looks like part of the isolation of the Russian economy, especially with the benefit of hindsight given by the invasion of the Ukraine in early 2022.
Mega-deals have lots of moving parts but two of the most tangible to broader audiences are the price and the timing. Cemex infamously got both of these wrong with its acquisition of Rinker in 2007 as it paid high just as the US subprime mortgage crisis started a wider global financial one. This was despite Cemex's emergence over the previous 15 years as a multinational force to be reckoned with due in part to the so-called 'Cemex Way' approach to management, acquisitions and integration. Clear winners from the big acquisitions over the last decade are harder to spot but CRH and UltraTech Cement look strong so far. Adani Group has certainly picked a lively time to make a purchase on this scale following a global pandemic with ongoing global supply chain issues and disruptions to energy and food markets.
