Indosat (ISAT) Partners with Lintasarta and Ainfrastruktur Indonesia Raya for Fibre Optic Cable Infrastructure
Infrastructure issuer PT Indosat Tbk (ISAT), together with PT Aplikanusa Lintasarta (Lintasarta) and investor PT Ainfrastruktur Indonesia Raya, has signed an amendment and restatement of the investment agreement (Amended & Restated Investment Agreement or A&R Investment Agreement), a conditional sale and purchase agreement (CSPA), and a shareholders agreement (SHA) on 6 May 2026.
According to the Indonesia Stock Exchange (BEI) disclosure page on Thursday (7/5/2026), these agreements outline the investment framework between the parties concerning the dark fibre infrastructure business and related systems operated and owned by ISAT and Lintasarta in Indonesia.
Indosat’s Director, Chief of Legal and Regulatory, and Corporate Secretary, Reski Damayanti, explained that initially, under the original investment agreement dated 23 December 2025, the company acquiring the target company was planned to be a publicly listed entity on the BEI.
However, the parties agreed to amend this provision, so the acquiring company for the target will no longer be a public company but a private one.
“The parties signed the A&R Investment Agreement to adjust the relevant provisions,” Reski stated from the BEI disclosure page in Jakarta today.
Reski continued that although the Conditional Sale and Purchase Agreement (CSPA) and Shareholders Agreement (SHA) have been signed, their effectiveness remains subject to the fulfilment of preconditions. Therefore, they will only become legally effective after all parties to the CSPA and SHA have met all preconditions.
“In particular, this A&R Investment Agreement serves as the initial document outlining the framework for the planned transaction,” Reski added. Its contents include general commitments from the parties, key stages of the planned transaction, and completion of the transaction, all subject to preconditions and other terms.
ISAT’s management believes that the signing of the A&R Investment Agreement, CSPA, and SHA will not have any significant or detrimental impact on the company’s operational activities, legal position, or business continuity.
ISAT and Lintasarta are respectively owners and managers of assets comprising a network of optic fibre cables. The investor, PT Ainfrastruktur Indonesia Raya, initially planned to acquire a company indirectly.
Subsequently, the parties intend to carry out a series of transactions to transfer assets to the target company and for the new company to acquire the target company through a combination of debt, non-cash capital contributions (inbreng), and cash injections by that company.
This planned transaction will make the parties direct shareholders in the new company, which will hold a majority stake in the target company.
Reski emphasised that, in addition to the A&R Investment Agreement, ISAT will regulate further provisions in separate definitive transaction documents.
