Dr. Rajan Mahtani is a noted businessman, philanthropist and charity worker in Zambia. For the past three decades, Dr. Rajan Mahtani has been successfully working for improving the social and economic infrastructure of Zambia. This has been achieved by several of his highly successful organisations, some of which are Mahtani Group of Companies, Finsbury Investments and Finance Bank Zambia. He is also known for his other ventures outside of Zambia, most popular of them being in the United Kingdom. For the past ten years, Dr. Rajan Mahtani has been fighting for the legal takeover of another of his company, Portland Cement Zambia. It is a noted cement-manufacturing factory in Zambia which was being contested by two major business parties in Zambia, one of them being Dr. Rajan Mahtani. The case was initially registered at the Lusaka High Court, where the case proceedings took for more than a decade. During these case proceedings, numerous evidences and testimonials were shared by Dr. Rajan Mahtani. However, the final decision given by the justice Nkonde was extremely controversial. According to this decision, Ventriglias are the only shareholders of the Zambezi Portland Cement.

To counter this misdirected judgement, the case was further taken to Court of Appeal. The judge at the Court of Appeal was justice Mwinde who gave the final judgement on 31st January 2019. This judgement was comparatively quicker as the final announcement came just nine months after the case was registered there. As per the final judgement, Dr. Rajan Mahtani owned Finsbury Investments is majority shareholder of the Zambezi Portland Cement with 58 percent shares. On the other hand, Ventriglias owned Ital Terazzo Limited holds just 42 percent shares and is the minority shareholder without any legal ownership over the factory. This decision also aligns with the original shareholders agreement established in the year 2007.

Based on this decision, it is clearly established that Dr. Rajan Mahtani is the owner of Portland Cement Zambia factory.
