Mazagon Dock Shipbuilders Ltd Q4 FY2025 Concall Summary

Key Takeaways

• A provision-driven margin reset, not an operational collapse: EBITDA margin fell to 13.74% in Q4 from 35.1% in Q3, almost entirely because of a Rs. 532 crores provision for two loss-making contracts. The underlying shipbuilding engine, having just delivered all four 15 Bravo destroyers ahead of schedule, remains intact.
• The order book could triple, and soon: Management sees a path from the current Rs. 32,000 crores to over Rs. 1.25 lakh crores, contingent on signing the P-75 additional submarine and P-75(I) contracts. The P-75 AS deal is at the contract-signing stage and expected as early as next month.
• Medium-term margin guidance is a deliberate reset to 15% PBT: Management calls the recent 28%+ margins an anomaly from large project completions and guides to a prudent 15%, in line with global shipyard norms, while hinting it hopes to do better.
• Capacity is doubling for a reason: Two CAPEX programs worth ~Rs. 4,000 crores are underway, submarine capacity has already moved from 6 to 11, and a new Nhava yard is being built. The infrastructure bet is sized for the P-75(I) and export opportunity ThyssenKrupp has flagged.
• What to watch next quarter: Whether the P-75 additional submarine contract actually gets signed, any movement on P-75(I) commercial negotiations, and the first quarterly read on how the provision for the two stressed contracts is evolving.

The Q4 Margin Reset: Provision, Not Operations

• The Rs. 532 crores provision was taken on two contracts: Fast Patrol Vessels for the Coast Guard and the Denmark export order. Both were bid in 2022-23, and component prices have since risen sharply in a global shipbuilding boom. Not all equipment has been ordered yet, so the provision is an estimate under AS-37.
• Subcontracting costs spiked as a percentage of sales because MDL is building ~27 ships simultaneously. The yard cannot handle all fabrication internally, so blocks are being outsourced, adding transportation and third-party costs. For smaller projects like exports and Coast Guard vessels, the subcontract model is the preferred approach anyway.
• Other project expenses also rose year-on-year because 27 ships are in early construction stages where material procurement is front-loaded. Large orders like 17 Alpha also required procurement of base and depot spares at ~15% of project cost.
• The provision will be reviewed quarterly and charged to P&L, with reductions based on reassessment. Management has not quantified the timeline for resolution.
• FY25 full-year margins still improved: EBITDA margin rose to 28.24% from 26.93%, and PBT margin to 27.2% from 26%, driven by the completion of high-margin 15 Bravo destroyers.

Capt. Jagmohan: "So it is safe to have a guidance of approximately 15%. And there are other shipyards who are listed and you can look at their profit margins and you can gauge what is the general range. We have exceeded the general profit margin significantly."

The Order Book Inflection: Submarines Are the Lever

• P-75 Additional Submarine contract is at the contract-signing stage, with all commercial negotiations with the Ministry of Defence completed. Management expects it "as early as next month," i.e., by June/July 2025.
• P-75(I) submarine contract is expected to be signed in FY26. The technical offer has been accepted by the Navy and MOD, but commercial negotiations have not yet begun. The collaboration with ThyssenKrupp involves significant transfer of technology and indigenization.
• The order book math: signing both submarine contracts adds at least Rs. 1 lakh crore. Adding one major surface ship contract (17 Bravo frigates at ~Rs. 70,000 crores, or MCMV at ~Rs. 44,000 crores) could push the order book toward Rs. 2-2.5 lakh crores.
• Revenue visibility from the current book: Of the Rs. 32,000 crores order book, approximately Rs. 24,000 crores will be executed across the next two years. The bulk of 17 Alpha (Rs. 13,493 crores) books in FY26 and FY27; 15 Bravo (Rs. 3,716 crores) finishes by FY27-28.
• Export optionality: The Denmark contract includes an option for four more ships, contingent on delivering the current six on time and within contractual terms. ThyssenKrupp has also indicated it will look to build global orders for Asia and South America at MDL.

Capt. Jagmohan: "See, it's like this. It depends upon whether we are able to sign the 75 (AS) and the 75 (I) submarine contracts quickly. That adds up at least to 1 lakh crore. And if we win one of the shipbuilding contracts of, let's say, 17 Bravo and the MCMV contracts, we could at least theoretically reach those order book levels."

Revenue & Margin Guidance: A Deliberate Reset

• Revenue growth guided at 10-15% for the near term, depending on how fast orders come and progress on the drawing board. FY26 is expected to deliver at least 10% more revenue than FY25.
• PBT margin guided to ~15% over the medium term. Management explicitly frames the 28%+ margins of recent quarters as unsustainable for a shipyard, driven by the one-time completion of large 15 Bravo destroyers.
• The "under promise, over deliver" signal: Management repeated that 15% is a prudent floor and that it hopes to do better, but wants to keep guidance conservative.
• Project-level revenue timelines are laid out: P-75 Kalvari (Rs. 2,400 crores) mostly in FY26 and early FY27; MRLC submarine repairs complete by mid-FY27; ONGC projects mostly by end of FY27; Coast Guard and multipurpose vessels by FY29-30. The P-75 AS project will contribute at least 10% of contract value as revenue in FY28.

Capt. Jagmohan: "Yes, we hope so. We would like to under promise and over deliver. But we would like to keep the guidance at 15%, which is considered to be good for a shipyard. But we are hopeful that we will do better."

Capacity Build-Out: Betting on the Order Pipeline

• Two major CAPEX programs totaling approximately Rs. 4,000 crores are underway: one for newly acquired land and one for the Nhava yard. Once operational, capacity will increase at least 2x, with exact contours to be determined at the consultancy DPR stage.
• Submarine capacity already expanded from 6 to 11 submarines, with a new submarine section assembly workshop set up. This prepares the yard for both the P-75 additional submarines and the six P-75(I) boats.
• Ship repair is a material, growing vertical: Submarine repairs (MRLC and AIP plugs) have already contributed ~Rs. 4,000 crores of revenue. The current wet basin and dry dock handle smaller vessels; once CAPEX is operational, MDL will be able to repair larger ships.
• Master Ship Repair Agreement with US Navy: MDL remains a contender, but current infrastructure cannot accommodate large vessels, so the company could not participate in a couple of offers. Nothing is expected in the immediate future.
• Debt funding for CAPEX remains an open question: management said it does not expect debt but will evaluate based on economic performance, stopping short of a clear commitment.

The Pipeline Beyond Submarines

• 17 Bravo frigates: The Navy is likely to issue an RFP shortly for this ~Rs. 70,000 crore project.
• MCMV project: At the Acceptance of Necessity stage, valued at ~Rs. 44,000 crores, with an RFP likely in a few months.
• Next-generation corvettes: Bids were opened but the order went to GRSE and GSL, not MDL.
• Shipbuilding clusters: The Ministry of Shipping is planning four large clusters by 2030, operational by 2035. MDL is in very early stages of examining tie-ups with global shipyards. Management gave a general answer when asked about a specific Korean shipyard tie-up reported in the news, neither confirming nor denying.
• Nuclear submarines: Management deflected, stating this is a call for the Indian Navy and MOD, and that nuclear submarines are built through the shipbuilding center in Vizag, not MDL.
