Samvardhana Motherson International Ltd. makes a corporate announcement

Verdict: The acquisitions temporarily increased Motherson’s consolidated leverage, but management did not disclose a separate debt impact or payback schedule for Yachiyo or SAS Autosystemtechnik. Its stated commitment was at the group level: reduce consolidated leverage to 1.0x or better within the next two to three quarters / by FY25-end. That benchmark was achieved, with leverage at 1.0x in Q2 FY25 and 0.9x by March 2025.

Leverage impact

Motherson’s reported leverage ratio is defined as effective net debt plus lease liabilities divided by LTM EBITDA. ^[1]

• In Q1 FY25, following the closure of several acquisitions including Yachiyo, management said net debt increased by approximately Rs 3,000 Crores. However, the increase was attributed to both M&A closures and higher working capital, partly related to the Red Sea disruption and volatile customer schedules; therefore, the acquisition-only contribution cannot be isolated. Consolidated leverage stood at 1.5x. ^[2]
• Management subsequently said debt should decline materially over the next two to three quarters, with the year-end objective being 1.0x or better, supported by working-capital normalization and operating cash flow. ^[3]
• The ratio reached 1.0x in Q2 FY25, aided by debt repayment, including approximately Rs 6,000 Crores of QIP proceeds used in November. ^[4]
• It stood at 0.9x as of March 2025, indicating that the group-level deleveraging target was met. ^[5]
• Leverage later moved to 1.1x in June and December 2025, before improving to a record 0.8x by March 2026. ^{[5] [6]}

What was—and was not—promised for Yachiyo and SAS

Yachiyo was among the acquisitions cited in the Q1 FY25 debt bridge. SAS Autosystemtechnik was an earlier 2023 acquisition, but management’s disclosed leverage commentary did not quantify its standalone contribution to net debt or EBITDA. ^{[7] [2]}

Accordingly, “return to pre-acquisition levels” was a consolidated objective, not an asset-specific one. Management did not provide a timetable such as “Yachiyo deleveraged in X quarters” or “SAS deleveraged by FYXX.” The separate management comment that integration and synergy realization could take up to one year or longer related to operational assimilation and margin improvement, not to a defined debt repayment schedule. ^[8]

Analytical implication: The acquisition program caused a temporary leverage step-up, but the group restored leverage below 1.0x within the stated timeframe. That demonstrates consolidated balance-sheet deleveraging, but it does not establish that Yachiyo or SAS individually returned to their pre-acquisition leverage or funding profile.

The mix explanation is only partly right. Motherson’s wiring harness business is large, but the latest disclosed segment data do not show it as lower-margin than Modules & Polymer. Wiring is therefore a contributor to the gap versus Sona BLW and Bosch only in the sense that its margin is below those peers’ company-wide margins—not because it is lower-margin than Motherson’s polymer business.

Current peer snapshot

For a TTM comparison through Q4 FY26, Motherson reported 11.9% ROCE and 9.7% EBITDA margin, versus 13.8% and 26.9% for Sona BLW, and 24.7% and 17.5% for Bosch. Bosch’s figures are standalone, while Motherson and Sona BLW are consolidated, so this is directional rather than fully like-for-like.^{[9][10][11][12][13][14]}

The latest Q1 FY27 EBITDA margins reinforce the ranking: Motherson was approximately 8.81%, derived from revenue of Rs 35,243.77 Crores and EBITDA of Rs 3,104.17 Crores; Sona BLW was 23.10%; and Bosch was approximately 13.48%, derived from EBITDA of Rs 818 Crores and revenue from operations of Rs 6,067.6 Crores.^{[15][16][17][18]}

Motherson’s actual segment bridge

Notes: † Derived from Motherson’s Q1 FY27 segment revenue and segment-result disclosures. The segment-result margin is a proxy, not a separately reported EBITDA margin; consolidated EBITDA also includes eliminations and equity-method adjustments.

On this disclosed basis:

• Wiring’s reported segment-result margin was 4.26 pp higher than Modules & Polymer.
• Because wiring represented 40.33% of the combined revenue of these two divisions, it lifted their combined segment-result margin by approximately 1.72 pp versus a scenario in which all of that revenue earned the Modules & Polymer margin. This is a mechanical mix calculation, not a peer-normalized estimate.
• Modules & Polymer was the larger business by revenue, but its reported segment-result margin was lower. Its larger asset base—Rs 43,720.56 Crores versus Rs 23,270.83 Crores for wiring—makes it more relevant to the ROCE discussion, although Motherson does not disclose segment ROCE on the same average-capital-employed basis as group ROCE.^[15][19]

What changed versus the prior year

Management said the Q1 FY27 consolidated margin improvement was primarily driven by Modules & Polymer restructuring and cost optimisation.^[20] The segment data support this as a year-on-year improvement driver, but not as evidence that Modules & Polymer is the higher-margin business in absolute terms: its implied segment-result margin improved from approximately 6.38% in Q1 FY26 to 6.85% in Q1 FY27, while wiring declined marginally from approximately 11.38% to 11.11%, derived from the reported segment figures.^[15]

Bottom line: wiring is high-revenue and its roughly 11% segment-result margin is still well below Sona BLW’s 23.1% company margin and above Bosch’s roughly 13.5% current-quarter margin only marginally. However, within Motherson, the reported data do not support the claim that wiring is the main low-margin drag versus Modules & Polymer. The more defensible conclusion is that Motherson’s consolidated margin gap reflects its broad global portfolio, segment and consolidation structure, and capital intensity; the precise portion attributable to wiring versus polymer cannot be isolated from reported disclosures.
