However, a final ruling is unlikely next week and the commission may hold more meetings, FSC officials said.

The regulatory probe centered on questions about Samsung BioLogics' sudden profits in 2015.

After years of losses, Samsung BioLogics posted a net profit of 1.9 trillion won ($1.76 billion) in 2015 after it changed the method used to calculate the value of its affiliate, Samsung Bioepis.

Samsung BioLogics has claimed that the change was in line with international accounting standards.

Before Samsung BioLogics went public in 2016, Samsung Electronics and Cheil Industries Inc. each owned 40 percent stakes in the biosimilar maker.

People's Solidarity for Participatory Democracy, an influential South Korean civic group, has argued that Samsung BioLogics may have inflated its profit to raise the value of the company for the benefit of Samsung Group's heir apparent Lee Jae-yong, who held a major stake in Cheil Industries at that time.

The civic group has said the suspected accounting breaches at Samsung BioLogics may have helped the controversial takeover of Samsung C&T Corp. by Cheil Industries Inc. in 2015.

The merger of two Samsung units was widely seen as a step to enhance Lee's control of Samsung Group, as his father Lee Kun-hee suffered a heart attack in 2014 and has been hospitalized since. (Yonhap)
