### Management Credibility

- **[CATALYST] European OEMs restructuring supply chains toward India** (NEUTRAL, IN_PROGRESS): The European opportunity remains active and has advanced in the sales pipeline. Management said European OEM and Tier-1 engagement had picked up meaningfully, approximately one-third of the increase in the business-development pipeline came from Europe, and many opportunities were at stages 3 or 4 with samples approved and commercial negotiations underway. No large European order was announced in Q3. (1 in progress across 1 tracked commitment)
  > Hopefully, in the next few quarters to come, we can win significant new orders from Europe, add them to our order book.
- **[METRIC] Capacity utilization and capex intensity** (NEUTRAL): Maintain high capital efficiency in the high-voltage motor and control-system businesses, with an expected revenue-to-capex ratio of at least 11–12x. — target: At least ₹11–12 of revenue for every ₹1 of capex (+4 more commitments)

- **[PRINCIPLE] OEM customer concentration risk and diversification** (NEUTRAL): Expand EV and hybrid customer and program coverage through new program wins and the DENSO partnership.
  > We have also added 2 new EV programs and 1 hybrid program, which takes our EV order book to 69 programs across 36 customers.
- **[TREND] Rising electronics and software content per vehicle** (NEUTRAL, IN_PROGRESS): The company reported that it is progressing toward industrializing its first in-cabin radar solution. Production launch was not yet confirmed. The relevant European safety-certification requirement was also deferred from 2026 to 2027. (5 in progress across 5 tracked commitments)
  > These nominations ... have an order value of, as you can see on the screen, about ₹8.2 billion in the lifetime, and they're expected both to start production in Q2 of FY 27.
- **[TREND] EV-specific component demand creating new market segments** (POSITIVE, EXCEEDED): The company reported 64 EV programs across 33 customers at the end of Q3 FY26, exceeding both the committed program count and customer count. (5 exceeded across 5 tracked commitments)
  > So, our end customer is working with other OEMs in Europe, and it is wide acceptability in the automotive sector. ... we are looking at a very high volume, as Vivek said, I mean, 3 to 4 times growth compared to last year.
- **[TREND] Indian component makers expanding global manufacturing** (POSITIVE, MET): The company executed strategic business additions during FY26, consistent with the stated acquisition and diversification strategy. (3 met, 1 in progress across 4 tracked commitments)

- **[TREND] Shift from component supplier to systems integrator** (NEUTRAL, IN_PROGRESS): The company moved from a stated future opportunity to concrete physical-AI commercial activity, including secured orders and an orderbook. (1 exceeded, 4 in progress across 5 tracked commitments)
  > Actually, 1 is this quarter, 1 is next quarter, 1 within 15 months.
- The presentation reports a revenue CAGR of 27.9% for FY17–9M FY26 annualized, exceeding the 24% commitment by 3.9 percentage points. (1 exceeded, 1 in progress across 2 tracked commitments) (POSITIVE, EXCEEDED)
  > 24% 5-year Revenue CAGR

### Business Model

- **[CATALYST] OEM production ramp across PV, CV, and 2W segments** (POSITIVE, Change: EXPANDING): Automotive remains the core business. In H1 FY26, automotive product revenue was approximately 91% of total revenue after including the disclosed non-automotive and railway mix, while the company reported total revenue growth of 10% year over year. The later baseline describes automotive products as 100% of revenue, indicating further concentration in automotive by Q1 FY27, although the baseline does not provide a directly comparable automotive revenue figure. (1 expanding)
  > Our overall revenue grew by 10% during the first half of the year
- **[METRIC] Capacity utilization and capex intensity** (NEUTRAL): The company has scale and financial strength from a diversified order book and a cash-rich balance sheet. Its Q1 FY27 net order book was Rs. 24,000 crore, 64% related to EVs, while net debt remained negative, meaning cash exceeded debt.
  > At the end of Q1 FY27, our net order book stands at 240 billion, with EVs accounting for 64%. ... Our net debt continues to be negative. Therefore, net debt to EBITDA ratio also continues in a negative territory.
- **[METRIC] EBITDA margin by product complexity tier** (NEGATIVE, Change: CONTRACTING): Profitability remained strong and improved versus the earlier historical phases. Average EBITDA margin increased from 25.0% during FY12–FY16 to 26.7% during FY17–9M FY26 annualized, a 1.7 percentage-point improvement, or approximately 6.8% relative growth. The latest presentation does not provide a standalone quarterly EBITDA margin, so the comparison is based on the disclosed period averages. (1 expanding, 4 contracting)
  > FY12–FY16 Avg. EBITDA margin 25.0%; FY17–9M FY26 Annualized Avg. EBITDA margin 26.7%.
- **[METRIC] Export revenue growth and geographic mix** (POSITIVE, Change: EXPANDING): The company materially shifted its revenue base toward India and Eastern markets during FY26. India reached 55% of Q3 revenue, while Eastern markets rose to 58% from 33% in the prior year. This reduced dependence on North America, whose share had nearly halved over the preceding nine months. (3 expanding, 2 shifted)
  > The share of our India business has increased to 55% in Q3... Eastern markets today can account for 58% of total revenues. This was 33% last year.
- **[METRIC] R&D expenditure as percentage of revenue** (POSITIVE, Change: EXPANDING): The technology moat was established through a transition from manufacturing to in-house design and engineering. The latest presentation reports 470+ R&D employees, 100+ software engineers, five R&D centres and 141 patents granted or filed. These are current capability figures, but no earlier comparable R&D or patent figures are disclosed, so the direction versus the prior quarter cannot be measured. (1 expanding)
  > Electrification, & Intelligence ... 470+ R&D employees ... 100+ Software engineers ... 141 Patents (granted + filed)
- **[PRINCIPLE] EV transition impact on component content per vehicle** (NEUTRAL, Change: STABLE): EV revenue contracted in the latest reported period despite remaining a substantial part of automotive sales. H1 FY26 BEV revenue fell 21% year over year, and its share of automotive product revenue declined from 36% in FY25 to 30% in H1 FY26. The baseline later shows EV-related orders still supporting strong automotive growth, but provides no directly comparable EV revenue share. (2 contracting, 2 stable)
  > H1 FY26 BEV revenue 4,752 mn; -21% H1 FY26 BEV revenue YoY growth; 30% H1 FY26 BEV Share in Automotive Product Revenue
- **[PRINCIPLE] OEM customer concentration risk and diversification** (POSITIVE, Change: EXPANDING): Customer concentration improved substantially over the longer comparison period. The top five customers' share fell from 62% to 51%, and the top ten share fell from 80% to 72%. This is particularly important because the largest EV customer's contribution fell from 23% to 6%, yet the company still doubled its revenue run rate since FY22. (5 expanding)
  > In Q2, the top 5 customers contribute 51% of total revenue. This is down from 62%, 3.5 years ago in FY22. Additionally, the contribution from our top 10 customers has been reduced to 72% from 80%... our largest EV customer, their contribution to our revenue declining from 23% in FY22 to a mere 6% no
- **[TREND] Rising electronics and software content per vehicle** (POSITIVE, Change: EXPANDING): The technology moat broadened from mechanical components toward integrated electric motors, controllers, software and radar sensors. The company validated a rare-earth-free motor designed entirely in-house and reported a technology roadmap spanning components, subsystems and complete systems. By the later baseline period, the company reported 141 patents granted or filed and more than 100 software engineers, indicating further strengthening, although those metrics were not disclosed in this October 2025 presentation. (2 expanding, 1 shifted, 1 new)
  > We have successfully developed, tested and validated Rare Earth Free Motors ... 100% designed and developed at Sona Comstar
- **[TREND] EV-specific component demand creating new market segments** (POSITIVE, Change: EXPANDING): The EV order pipeline expanded during Q2 FY26 even though current BEV revenue was weak. Awarded EV programs increased from 60 at the end of Q1 FY26 to 62 at the end of Q2 FY26, across 32 customers. This creates longer-term EV revenue visibility, with 29 of the 62 programs not yet in production. (5 expanding)
  > EV Programs awarded across 32 customers as at the end of Q1 FY26 60 ... EV Programs awarded across 32 customers as at the end of Q2 FY26 62
- **[TREND] Indian component makers expanding global manufacturing** (POSITIVE, Change: EXPANDING): The revenue mix shifted materially away from passenger vehicles toward non-automotive and railway-related activities. Passenger vehicles declined from 71% of FY25 revenue to 53% in H1 FY26, while non-automotive increased from 9% to 28%. Railway became a new disclosed business contribution after acquisition and represented 6% of the H1 FY26 order book; the presentation states Q2 FY26 was the first full quarter of railway revenue. (2 shifted, 2 expanding, 1 new)
  > By Market segment FY25 PV 71% ... Non-Automotive 9%; H1 FY26 PV 53% ... Non-Automotive 28%
- **[TREND] Shift from component supplier to systems integrator** (POSITIVE, Change: SHIFTED): Automotive products remained the company's core business, but the business model broadened during the period through the acquisition of the Railway business and the addition of Sensors & Software capabilities. The presentation does not disclose quarterly automotive revenue or a separate automotive revenue share, so the change in automotive revenue cannot be quantified. The latest disclosed state in this document is 9M FY26 annualized revenue of ₹42,700 million, with 33% of auto-product revenue coming from battery-electric-vehicle products. The Railway business was acquired on 1 June 2025 and is therefore a new adjacent revenue stream rather than a discontinued automotive activity. (1 shifted, 1 new)
  > 4 Business Verticals: Driveline, Motor, Sensors & SW, Railway; 33% BEV revenue share in auto products; ₹42,700 mn 9MFY26 annualized revenue.
- Total revenue expanded strongly in the latest reported quarter, although the business mix shifted because railway revenue was consolidated for the first full quarter. Q2 FY26 revenue rose 24% year on year to ₹1,144 crore. First-half revenue rose 10% to ₹1,994 crore. The document does not disclose a directly comparable automotive-only revenue figure. (5 expanding across 1 engine) (POSITIVE, Change: EXPANDING)
  > Our revenue for the quarter grew to 12,310 crores, a growth of 54% over the first quarter of last year. BEV revenue grew by 107% to 436 crores over the same quarter last year. BEV revenue constituted 44% of our automotive product sales.

### Future Growth

- **[CATALYST] European OEMs restructuring supply chains toward India** (POSITIVE, Trend: NEW_TREND): The current call does not repeat the earlier ₹24,000-crore Indian market estimate or provide a new market-size data point. Instead, it reports four new driveline wins across Europe, North America and India, covering EV and hybrid applications. This supports expanding commercial traction, but it does not establish a multi-quarter quantitative trend in the addressable-market estimate. (1 new trend across 1 signal)
  > We won 4 new driveline orders... we've won 3 driveline orders from European OEMs in a single quarter... One of the four orders this quarter was for a hybrid platform.
- **[METRIC] Capacity utilization and capex intensity** (POSITIVE, Trend: NEW_TREND): The company reports a current footprint of 12 manufacturing plants, five R&D centres, one tool-and-die shop, eight warehouses and three engineering capability centres. No prior quarterly capacity figures or plant-addition plan are provided, so the signal is new rather than demonstrably expanding. (5 new trend across 5 signals, 1 leading indicator)
  > In high voltage systems, for ₹1 of capex, you can get 8 to 9 rupees of revenue easily... It will be at least 11-12... it is more about the technology thing... it is not a very capital intensive thing. It is more engineering intensive.
- **[METRIC] EBITDA margin by product complexity tier** (NEUTRAL): Profitability has remained strong, with average EBITDA margin of 25.6% from FY22 to annualised Q1 FY27 and 25.7% across FY99 to annualised Q1 FY27. The company’s move toward electric, intelligent, software-enabled, and new vertical products could support a higher-value mix, but no future margin target is provided. — Average EBITDA margin: 25.6% latest-period average versus 25.7% long-term average; no change quantified
  > FY22–Q1 FY27 Ann. Avg. EBITDA margin 25.6% Revenue CAGR 22.3% ... FY99 – Q1 FY27 annualized Avg EBITDA margin 25.7%
- **[METRIC] R&D expenditure as percentage of revenue** (POSITIVE, Trend: NEW_TREND): The current footprint comprises 12 manufacturing facilities, five R&D centres, and five engineering capability centres, supported by more than 470 R&D employees and 100 software engineers. The document does not provide an earlier comparable facility count or a stated plant-addition plan, so expansion momentum cannot be quantified. (1 new trend across 1 signal, 1 leading indicator)
  > 470+ R&D employees ... 100+ Software engineers ... 141 Patents (granted + filed) ... 5 R&D centers
- **[PRINCIPLE] EV transition impact on component content per vehicle** (NEGATIVE, Trend: REVERSING): The presentation reports BEV revenue of ₹12,235 million in FY25, falling to ₹4,752 million in H1 FY26, or approximately ₹9,504 million annualized. BEV revenue declined 21% year on year in H1 FY26, and its share fell from 36% in FY25 to 30%. This is a clear reversal after several years of expansion. (3 reversing across 3 signals)
  > BEV revenue and BEV revenue share over the years ... FY25 12,235 ... 36% ... H1 FY26 4,752 ... 30%; H1 FY26 BEV revenue declined by 21%
- **[PRINCIPLE] OEM customer concentration risk and diversification** (POSITIVE, Trend: ACCELERATING): The company expanded from 22 customers and two plants in an earlier phase to 47 customers and nine plants in the phase following the Comstar acquisition. This is a clear structural expansion in customer and manufacturing reach, but the presentation does not provide quarterly observations or a current order-book trend. (1 accelerating, 2 new trend, 2 steady across 5 signals)
  > Phase - 2 • 22 Customers • 2 Plants • 2 Products ... Phase - 3 • Acquisition of Comstar • 47 Customers (37+10) • 9 Plants (5+4) • 10 Products (5+5)
- **[TREND] Rising electronics and software content per vehicle** (POSITIVE, Trend: ACCELERATING): The EV programme pipeline is expanding: the company reports 69 programmes across 36 customers and added two new EV programmes plus one hybrid programme. BEV revenue represents 33% of auto-product revenue in 9M FY26, but the presentation does not disclose multiple quarterly BEV-revenue values. The combination of a broad programme base and new wins indicates an accelerating strategic growth signal, though revenue acceleration itself cannot be confirmed from the disclosed data. (1 accelerating, 1 new trend across 2 signals, 1 leading indicator)
  > Together, these three orders, they add ₹6 billion to our Robotics and Physical AI orderbook, which takes the total order book for this new vertical to ₹8 billion.
- **[TREND] EV-specific component demand creating new market segments** (POSITIVE, Trend: ACCELERATING): The opportunity is stated as above ₹24,000 crore in India by 2030 and approximately three times larger by 2035. This is a newly disclosed long-term opportunity-size signal, with an accelerating market outlook, but it is not yet supported by quarterly revenue or order data. (5 accelerating across 5 signals)
  > We delivered the highest ever BEV revenue and BEV mix during the quarter, and BEV revenue grew 107% despite EV demand in the US remaining weak. We have also added 2 new EV programs and 1 hybrid program, which takes our EV order book to 69 programs across 36 customers.
- **[TREND] Indian component makers expanding global manufacturing** (POSITIVE, Trend: ACCELERATING): Non-automotive revenue increased from 9% of FY25 revenue to 28% of H1 FY26 revenue, while railway was included for the first full quarter after acquisition. This is a newly visible diversification-led growth trend, although the document does not provide a longer quarterly history. (1 new trend, 1 discontinued, 1 accelerating, 1 steady across 4 signals, 2 leading indicators)
  > West + East ... We aspire to replicate the same 10x growth in the next decade focusing on the new strategy
- **[TREND] Shift from component supplier to systems integrator** (POSITIVE, Trend: NEW_TREND): Diversification beyond automotive is accelerating. Revenue from non-automotive sectors increased from 10% of H1 revenue to 29% in H1 FY26, led mainly by railway products. The railway acquisition also brings a Rs. 130 crore order book expected to be executed largely within 12 months. (2 accelerating, 3 new trend across 5 signals, 1 leading indicator)
  > We see 3 distinct revenue streams for ourselves. The first is advanced components and subsystems... The second is the perception stack and engineering services around perception... The third and perhaps the most ambitious is manufacturing of selected full robotic platforms. Initially our focus will 
- The company reported a strong near-term acceleration in consolidated revenue: Q3 FY26 revenue grew 39% year on year, versus 19% growth for 9M FY26. This is a quarterly operating result rather than evidence that the longer-term ambition to repeat 10x growth has been achieved. The strong latest-quarter result supports the ambition but does not establish a multi-quarter trajectory for the 10-year target. (2 accelerating, 1 decelerating, 2 new trend across 5 signals, 2 leading indicators) (POSITIVE, Trend: ACCELERATING)
  > We grew >10x in 10 years (FY15-FY25) by focusing on three key strategic decisions ... We aspire to replicate the same 10x growth in the next decade focusing on the new strategy ... Mobility Electric + Intelligent & Connected West + East New Product Verticals

### Risk Assessment

- **[CATALYST] European OEMs restructuring supply chains toward India** (POSITIVE): The competitive environment was changing sharply. Three direct European competitors entered insolvency proceedings, creating both a threat of supply-chain disruption and an opportunity for Sona Comstar to win replacement business. Customer inquiries increased, but the company had not yet converted them into confirmed major orders. Therefore, the immediate competitive pressure may have eased in Europe, but execution and pricing uncertainty remained high. The most appropriate classification is EASING because competitor failures reduced near-term competitive intensity. (2 easing)
  > In the past 6 months, 3 of our direct competitors in Europe have filed for insolvency proceedings. This has resulted in an unprecedented increase in inquiries from European customers to us.
- **[CATALYST] OEM production ramp across PV, CV, and 2W segments** (NEGATIVE): The company reported a large ₹236 billion net order book, equal to 6.8 times FY25 revenue, with EV programmes accounting for ₹165 billion or 70%. However, ₹36 billion of orders were consumed in Q2 FY26 from mature and ramp-up programmes, while only ₹10 billion of new orders were added. The order book therefore declined from ₹262 billion at Q1 FY26 to ₹236 billion at Q2 FY26. Management also states that the order-book calculation includes discounts for possible delays or launch changes, confirming that conversion is uncertain. The falling order book and high EV exposure make this risk high. (2 intensifying, 1 stable)
  > 262 bn Orderbook at the end of Q1 FY26; 36 bn Orders consumed ... during Q2 FY26; 10 bn Orders added ... in Q2 FY26; 236 bn Orderbook at the end of Q2 FY26; EV: ₹165 billion (70%)
- **[CATALYST] Mandatory domestic content requirements for EVs** (NEUTRAL): There is insufficient new evidence to determine whether this risk improved or worsened. Management discussed broader supply-chain disruption, rare-earth restrictions and supplier restructuring, but did not quantify customer stoppages or Sona Comstar sales lost because of another supplier’s shortage. (1 insufficient_data)
  > China's restrictions on the supply of heavy rare earth magnets to India continues. In response, we have shifted to alternative motor designs that do not use heavy rare earth magnets.
- **[METRIC] Capacity utilization and capex intensity** (NEGATIVE, Risk: MODERATE): The presentation provides concrete evidence of conversion and utilisation pressure. Fixed-asset turnover declined from 3.4 times in March 2025 to 3.0 times in September 2025, while working-capital turnover fell from 5.0 to 4.2 times. These measures suggest that the larger asset base and order pipeline were not yet generating revenue at the earlier rate. The fact that 43 of 62 EV programmes were still in ramp-up or not yet in production further supports a risk of delayed customer production. (1 intensifying, 1 stable)
  > 12 Manufacturing facilities ... 5 Engg. Capability Centers
- **[METRIC] Revenue content per vehicle by OEM platform** (NEUTRAL, Risk: MODERATE): The high-voltage and hybrid business has a long automotive development cycle. Even after winning an order, commercial production may take about three years, delaying cash generation and increasing the risk that customer programmes change before launch. [EXECUTION]
  > Even if you get a PO today, it'll take 3 years to SOP, right? I mean, that's how automotive works. 32 months is the cycle.
- **[METRIC] EBITDA margin by product complexity tier** (NEGATIVE, Risk: HIGH): The margin risk clearly intensified during the reported period. In Q2 FY26, revenue grew 24% year on year to ₹11,435 million, but EBITDA margin declined from 27.6% to 25.3%, a fall of approximately 2.3 percentage points. For H1 FY26, revenue grew 10%, while EBITDA fell 3% and margin dropped from 27.8% to 24.6%, down about 3.2 percentage points. Management attributed the deterioration to adverse product mix and operating leverage. This is the strongest directly observed earnings risk in the document. (5 intensifying, 1 high-severity)
  > Inflation continues to be the biggest near-term challenge. Commodities and other input costs remain elevated. They have impacted margins during the quarter... costs pass through with automotive customers always lag inflation, so they come a little later. This, along with the arithmetic impact on bot
- **[METRIC] Export revenue growth and geographic mix** (NEGATIVE, Risk: MODERATE): The risk remains material. Global market share declined from 8.8% to 8.7% for differential gears and from 4.4% to 4.2% for starter motors between CY24 and CY25. The company also reports that global market share is not uniformly improving despite adding programmes and customers. This is concrete evidence of slight competitive pressure, although the company continues to hold strong Indian positions in differential gears. (1 intensifying)
  > Global Market Significance ... Win against global firms in the world
- **[METRIC] R&D expenditure as percentage of revenue** (NEUTRAL, Risk: MODERATE): This was an emerging execution risk in Oct 2025. Robotics was still at the collaboration and prototype-development stage, while management explicitly cautioned that new categories could take three to five years to generate meaningful revenue. The risk therefore remained high and had not eased during this document period. No directly comparable Sep 2026 metric is provided here. (1 emerging, 1 stable)
  > 470+ R&D employees ... 100+ Software engineers ... 141 Patents (granted + filed) ... 5 R&D centers
- **[PRINCIPLE] China-plus-one strategy driving export opportunities** (POSITIVE): Supply-chain risk emerged and was material in the older period. Heavy rare-earth magnet supply from China was disrupted from 8 April, affecting EV traction-motor production in Q1. A separate semiconductor issue involving Nexperia could affect customers' ability to build complete vehicles, while a Novelis plant fire reduced production of an important customer model. Management assessed the direct effect as limited or not major for this quarter, but noted that customer-level shortages can halt vehicle production even if Sona Comstar can supply its own parts. The risk was therefore EMERGING, with severity still HIGH because the company cannot control customer-side bottlenecks. (1 emerging, 1 easing)
  > China has stopped supplying heavy rare-earth magnets. This shortage has impacted the production of EV traction motors for us in Q1... the larger issue... is if our customers cannot resource; whatever we can do at our end does not really help because a 99% car has no value.
- **[PRINCIPLE] EV transition impact on component content per vehicle** (NEGATIVE, Risk: HIGH): The risk was already material in H1 FY26 because BEV revenue fell 21% year on year to ₹4,752 million, despite BEV products still representing 30% of automotive product revenue. This indicates that EV-related demand was weak in the latest reported period, although the company continued expanding its EV programme pipeline from 60 to 62 programmes. The combination of falling realised EV revenue and continued strategic investment means the risk was worsening operationally, not resolved. (1 intensifying, 4 easing, 3 high-severity)
  > We aspire to replicate the same 10x growth in the next decade focusing on the new strategy ... Electric + Intelligent & Connected
- **[PRINCIPLE] OEM customer concentration risk and diversification** (POSITIVE, Risk: MODERATE): The concentration risk appears to have eased structurally. On an annualised Q2 FY26 basis, the largest disclosed customer represented 20% of revenue, while the next largest represented 10%; the combined share of the top two was therefore 30%, compared with 36% for the top two customers in FY22. The share of 'Others' also increased from 19% to 28%. This indicates better customer diversification, although a 20% largest-customer exposure remains material. (2 easing)
  > Phase - 3 • Acquisition of Comstar • 47 Customers (37+10)
- **[PRINCIPLE] PLI-driven localization and import substitution** (NEUTRAL, Risk: MODERATE): Automotive emission and localisation rules can change the technology requirements and cost structure for suppliers. Stricter emission standards may accelerate the move away from some conventional components, while domestic-content or incentive rules may require additional local investment and compliance. Loss or delay of government incentives could reduce expected returns on new capacity. [REGULATORY] (+1 more risk)
  > ₹1.97 lakh Cr worth of incentives across 14 sectors; targeting 14 lakh jobs creation ... REPM Scheme ₹7,280 Cr outlay for 6,000 MTPA mfg. capacity for rare earth magnets
- **[TREND] Rising electronics and software content per vehicle** (NEGATIVE, Risk: MODERATE): The risk is emerging, although initial evidence is positive. Sona Comstar has secured three robotics-related orders worth ₹6 billion, taking the robotics order book to ₹8 billion, but management described the business as small and acknowledged that the market and product generations are still evolving. Most orders are expected to begin production within a quarter to 15 months, while the company has limited experience in forecasting product lifecycles and returns in this segment. (1 emerging, 1 high-severity)
  > Most of this will start production, let's say within 12 to 15 months max... there will be generations. I think unlike automotive, this generation changes will happen more frequently.
- **[TREND] EV-specific component demand creating new market segments** (NEGATIVE): EV demand execution weakened in the latest period: BEV revenue declined 17% year on year in Q2 FY26 and 21% in H1 FY26. The EV programme count increased from 60 to 62, but the majority of programmes were still not fully ramped: 43 of 62 programmes were in ramp-up or not yet in production. Therefore, the order pipeline did not yet translate into revenue, increasing the risk of delayed conversion and customer launch timing. (4 intensifying, 1 easing)
  > BEV Revenue declined by 17% and constituted 32% of total automotive product sales
- **[TREND] Indian component makers expanding global manufacturing** (NEGATIVE, Risk: HIGH): The risk was high and increasing in the older period because the company had recently acquired the railway business, was ramping a Mexico plant, and was adding robotics and suspension products. The railway business had only been fully owned for about four months and required capacity expansion, new product approvals and operational integration. Management also acknowledged that future order-book reductions could recur if visibility weakens. This supports an INTENSIFYING trajectory for the Oct 2025 period; there is insufficient comparable evidence in this document to reassess against Sep 2026. (4 intensifying, 1 stable, 1 high-severity)
  > We grew >10x in 10 years (FY15-FY25) ... We aspire to replicate the same 10x growth in the next decade focusing on the new strategy
- **[TREND] Lightweighting driving material substitution** (NEUTRAL, Risk: MODERATE): The risk is stable rather than resolved. Commodity prices rose sharply, but management stated that pass-through is incomplete for steel contracts. Although reported EBITDA margins remained close to 25%, the company acknowledged that commodity pass-through itself can lower the margin percentage because both revenue and costs increase. (1 stable)
  > We need to move from labour cost arbitrage to engineering cost arbitrage to climb this ladder ... Improvement can be achieved by 1. Automation of manufacturing processes 2. Moving upward in the value chain
- **[TREND] Shift from component supplier to systems integrator** (NEGATIVE, Risk: HIGH): The execution risk was elevated because Q2 FY26 was the first full quarter containing railway revenue after the acquisition. Management also reported that the operating margin fell because of product mix and operating leverage, while H1 returns declined to 15.8% ROCE and 12.8% ROE from 18.4% and 17.7% respectively in March 2025. These returns include capital deployed for the NOVELIC and Railway acquisitions and were normalised using annualised railway results, so the new businesses had not yet demonstrated mature returns. (1 intensifying, 1 easing, 1 emerging, 1 high-severity)
  > In this JV, Denso will hold the majority stake, contribute the relevant technology and intellectual property, and lead the business from a management perspective.
- Execution complexity is increasing. Management is expanding from automotive into mobility, robotics and physical AI, pursuing a look-east strategy, integrating the railway acquisition and launching two Denso JVs. The company states that acquired businesses already contribute around 40% of revenue, while the new strategy involves larger investments and decisions. Although management cites prior execution capability, the broader scope raises the execution burden rather than reducing it. (1 intensifying, 2 emerging, 1 stable, 1 insufficient_data, 4 high-severity) (NEGATIVE, Risk: HIGH)
  > Margins were heavily impacted by input cost inflation, labor cost increases as well as the timing gap in the customer recoveries or the pass-throughs.

### Scenario Analysis

- Sona BLW Precis. is an automotive components manufacturer focused on precision forgings and electric-vehicle drivetrain products, while the AI Revolution scenario primarily targets AI software, IT/BPO automation, data-center infrastructure, power systems, and related suppliers. The company may use AI internally or experience indirect effects through automakers' technology investment and changing vehicle demand, but the evidence does not show that it supplies AI infrastructure or that AI materially drives its core revenue, cost structure, regulation, or competitive position. (NEUTRAL)
- The direct energy shock does not hit Sona BLW through crude or LNG sales, but higher fuel, freight, packaging, energy and crude-linked material costs can compress margins before OEM customers compensate the company. Its global automotive footprint increases exposure to shipping delays, insurance costs, inventory requirements and customer production interruptions, while rupee depreciation may simultaneously raise imported-input costs and improve export competitiveness. If oil prices remain elevated, vehicle affordability and OEM budgets could weaken in the near term, potentially delaying programs despite Sona BLW's strong order book. Over time, expensive petrol and diesel could accelerate hybrid and EV adoption, supporting demand for its motors, differentials and powertrain systems, but this structural benefit is gradual and does not offset the immediate margin risk. (NEUTRAL)
  > Inflation continues to be the biggest near-term challenge. Commodities and other input costs remain elevated. They have impacted margins during the quarter. April was tough, May was even tougher, but June showed improvement. As material costs passed through and other cost reduction and mitigation me
