contextRef="OneI">The proposal is for forming a joint venture company (JVCo.) between Cochin Shipyard Limited (CSL) and Drydocks World Dubai – FZCO (DDW) with each party holding 50% in the equity share capital of the JVCo. The JVCo. is proposed to be formed for owning, operating and managing the International Ship Repair Facility (ISRF) of CSL at Willingdon Island, Kochi for undertaking dry-docking, maintenance, repair and overhaul of commercial and naval vessels below 130 meters of length and 6,000-tonne weight. Further, the joint venture also envisages capacity augmentation of the ISRF through the addition of ten workstations.

ISRF has been developed over an area of around 30 hectares, comprising both land and water areas, at Willingdon Island, Kochi, leased from the Cochin Port Authority for a period of 60 years. The facility can handle vessels of up to 130 metres in length and was constructed at a cost of Rs. 970 Crores. It has a 6,000-tonne capacity ship lift and transfer system, six workstations and around 1,400 metres of berthing space. The facility can undertake repair of up to six vessels simultaneously and has an annual throughput capacity of up to 82 ships. The facility was inaugurated by the Hon’ble Prime Minister, Shri Narendra Modi, on January 17, 2024 and the commercial operations commenced on August 12, 2024. The ISRF reported revenue of Rs. 207.33 Crores during the financial year 2025-26, which is about 4.81% of the total revenue from operations of CSL. The value of the ISRF arrived at based on third party independent valuations is Rs. 1,800 Crores, which is about 30.55% of CSL’s net worth of Rs. 5,892.83 Crores as on March 31, 2026.

DDW is a DP World company and a leading provider of marine and offshore services for the shipping, oil &amp; gas, and renewable energy sectors, with operations covering ship repair, vessel conversion and offshore energy projects. DDW has more than four decades of experience in the maritime and offshore sectors and undertakes over 300 projects annually. DDW’s facility in Dubai is the largest ship repair facility in the Middle East. Established by HH Sheikh Rashid bin Saeed Al Maktoum’s royal decree in 1983, DDW became a part of the DP World group in 2018. DDW's capabilities extend beyond conventional ship repair to include vessel conversions, FPSO refits, offshore fabrication and projects associated with the renewable energy sector. DDW have completed more than 9,000 ship repair, maintenance and upgrade projects since its inception and serves clients globally, including in the Middle East, Asia, Europe, Africa and the Americas.

The joint venture is proposed to leverage the complementary strengths, expertise and capabilities of CSL and DDW in the ship repair sector. It is expected to create synergies between the two entities and facilitate the adoption of global best practices, advanced technologies and efficient processes in the domestic ship repair ecosystem, thereby improving the quality, efficiency and turnaround time of ship repair services. It is also expected to augment ship repair capacity in the country, strengthen the domestic ship repair infrastructure and enhance India’s capability to undertake complex and high-value ship repair projects. The initiative is also aligned with the objectives of Maritime India Vision 2030 (MIV 2030) and Maritime Amrit Kaal Vision 2047 (MAKV 2047) and supports the Government of India’s vision of Aatmanirbhar Bharat by promoting self-reliance in the maritime sector.</in-capmkt:ObjectsAndImpactOfAcquisitionIncludingButNotLimitedToDisclosureOfReasonsForAcquisitionOfTargetEntityIfItsBusinessIsOutsideTheMainLineOfBusinessOfTheListedEntity><in-capmkt:WhetherAnyGovernmentalOrRegulatoryApprovalsRequiredForTheAcquisition contextRef="OneD">Yes</in-capmkt:WhetherAnyGovernmentalOrRegulatoryApprovalsRequiredForTheAcquisition><in-capmkt:ProvideBriefDetailsOfAnyGovernmentalOrRegulatoryApprovalsForTheAcquisition contextRef="OneI">The materialisation of the proposal would require the approval of the Cochin Port Authority, the Government of India (Ministry of Ports, Shipping and Waterways (Administrative Ministry) and Department of Investment and Public Asset Management, Ministry of Finance) and the Shareholders of the Company.

Further, the joint venture also envisages capacity augmentation of the ISRF through the addition of ten workstations. Both CSL and DDW will be equal partners in the JVCo. holding 50% each in the share capital of the JVCo. The JVCo. shall issue equity shares to CSL and DDW at face value or such value as may be determined by an Independent Valuer.

Significant terms of the joint venture agreement: All rights as are customary in similar transactions including transfer, restrictions, information rights etc. The Joint Venture Agreement is proposed to be signed on September 11, 2026 and the other agreements will be signed upon incorporation of the JVCo. and receipt of all requisite approvals. CSL and DDW are not related parties and hence, the transaction does not fall within the ambit of related party transactions. Further, the promoter/ promoter group/ group companies of CSL do not have any interest in DDW. However, since the transfer of ISRF will be to the JVCo., wherein CSL will hold a 50% shareholding, the business transfer transaction will qualify as a related party transaction and is being undertaken at arm’s length basis. CSL shall procure the shareholders’ approval as per the applicable requirements of the Companies Act, 2013 and the SEBI LODR Regulations. The transfer of ISRF undertaking to the JVCo. is outside the Scheme of Arrangement. Further, CSL shall procure the shareholders’ approval as per Regulation 37A of the SEBI LODR Regulations and Section 180 of the Companies Act, 2013, wherever applicable. No potential conflict of interest is envisaged to arise out of the proposed transaction.</in-capmkt:AnyOtherBriefSignificantInformationForTheAcquisition></xbrli:xbrl>
