Marathon Nextgen to take full economic control of Monte South in Byculla
The deal would end a shared-risk arrangement on a large South Mumbai mill-land project and move the listed developer to 100% economic interest.

Key points
- On 31 October 2026, Marathon Nextgen Realty's board approved buying the outgoing partner's additional 60% in Swayam Realtors and Traders LLP for up to ₹335 crore.
- The consideration is up to ₹135 crore in cash plus a ₹200 crore bank guarantee.
- After completion, the company would hold 100% economic interest in the Monte South project in Byculla, up from 40%.
- Completion is expected within two months of the necessary approvals, and shareholder approval for related-party financing is still pending.
On 31 October 2026, the board of Marathon Nextgen Realty approved the purchase of an additional 60% economic interest in Swayam Realtors and Traders LLP (SRTL), the joint venture that holds the Monte South project in Byculla, Mumbai. The total consideration is up to ₹335 crore. The listed developer described the transaction, in its stock exchange filing, as an acquisition of full economic interest in Monte South.
Payment structure and what changes
The company's disclosure splits the ₹335 crore into up to ₹135 crore in cash and a ₹200 crore bank guarantee. Before the deal, Marathon Nextgen held 40% economic interest in SRTL. On completion, it would hold 100% economic interest in Monte South. Because SRTL is a limited liability partnership, the stake is an economic interest and not a transfer of listed shares.
The filing describes the seller only as the outgoing partner. It does not set out a payment timetable, a valuation method or the conditions attached to the bank guarantee, and it does not name the bank that would issue it. Buyers of Monte South flats are not affected by the filing in any stated way. The company's disclosure points to a change in who owns the project's economics, not in sales terms.
The company has also sought shareholder approval for related-party transactions that support the LLP. These cover direct investments, loan provisions, and guarantees or security for loans taken by the LLP. The shareholder vote has no date in the material available, and the deal is expected to complete within two months of receiving the necessary approvals.
The project and its location
Monte South is being built on the Khatau Mills land in Byculla, one of the larger former mill plots in South Mumbai. The residential campus comprises four towers rising over 64 storeys, with a total residential sale carpet area of over 1.6 million sq ft. A separate office and retail component, Monte South Commercial, is being developed in a joint venture with Adani Realty, announced on 20 October 2025.
In its quarterly release dated 22 October 2026, the company said construction at Monte South is progressing as planned. Pre-sales at the project grew 16% in the quarter ended September 2026. The company has not published a launch date, price band or possession date for the project in the material available, and this article does not state them.
Byculla Railway Station on the Central Line is the nearest main rail link. Mahalaxmi Metro Station on Line 3 is about 1 km away. The Eastern Freeway and Dr Babasaheb Ambedkar Road give road access, and Nariman Point and Lower Parel can be reached in about 20 minutes. A skywalk linking the rail station, Metro Line 3 and the monorail at Mahalaxmi is nearing completion, though no completion date has been fixed. Metro Line 11 is planned to serve Byculla, but it has no confirmed opening date. One estimate puts operation around 2030.
What it means for investors and the company's pipeline
An analyst view on the deal argues that the company would capture 100% of future revenue and profit from Monte South, rather than sharing 60% with its joint-venture partners. The same analysis says the move shifts the company from a shared-risk model toward direct control of a core Mumbai asset. It also notes that the bank guarantees would be a contingent liability on the consolidated balance sheet. These are analytical views, not company statements.
The company's release for the quarter ended September 2026 reported residential pre-sales up about 70% quarter on quarter, and its affordable and mid-income portfolio up 155%. Chairman and Managing Director Chetan Shah said the company is adding projects selectively in well-connected locations, with no net debt. The company has also reported two Mumbai redevelopments through its subsidiary Sunset Spaces: a Versova project on about 1.5 acres with an estimated gross development value above ₹450 crore, subject to approvals, and a Sewri cluster redevelopment with an estimated gross development value of about ₹450 crore. The company's release puts their combined value at about ₹900 crore.
What to watch next
- The shareholder vote on related-party financing for SRTL, for which no date has been given.
- Completion of the SRTL stake purchase, expected within two months of the necessary approvals.
- Whether the ₹200 crore bank guarantee is called or released after completion.
