### Management Credibility

- **[CATALYST] Broker Industry Consolidation** (POSITIVE, MET): Management confirmed that the consolidation of the Fisdom acquisition occurred in October, and its financials are reflected in the Q3 FY26 results. (2 met across 2 tracked commitments)
  > Furthermore, Fisdom, which we recently acquired, at its existing run-rate would add 3 - 4% to Revenue from Operations.
- **[CATALYST] Leveraged Trading Product Expansion** (POSITIVE, IN_PROGRESS): The MTF book market share increased significantly from 0.7% in Q3 FY25 to 2.0% in Q3 FY26. The MTF book value grew from ₹5,424 Mn to ₹23,074 Mn YoY. (1 in progress across 1 tracked commitment)
  > We believe we are still in the nascent stages of this journey and will continue to grow, led by higher penetration, ultimately leading to a fair market share aligned with that of our Stocks Average Daily Turnover (ADTO).
- **[METRIC] CAC and LTV Economics** (NEUTRAL): Management intends to evaluate Customer Acquisition Cost (CAC) and marketing spends on an annual basis rather than quarterly.
  > We believe that the right lens to look at CAC and marketing spends is on an annual basis.
- **[METRIC] Derivatives Revenue Concentration** (POSITIVE, IN_PROGRESS): The company is successfully scaling non-derivative segments; Commodities now contribute 4% to the top line, and MTF contributes 6%, showing progress toward diversification. (2 in progress across 2 tracked commitments)
  > So I think it is beyond 50, definitely it can come below 50. But that is like output number in the way to look at where if everything else goes or grows faster, this definitely can come off.
- **[PRINCIPLE] CAC Leverage and Viral Growth** (NEUTRAL): The company plans to maintain Customer Acquisition Cost (CAC) within established annual guardrails through seasonal spending optimization. — target: Within annual guardrails
  > And that is always worked for us to reduce and keep the CAC within the guardrails at the annual basis.
- **[TREND] Beyond Brokerage Income Streams** (NEGATIVE, MISSED): The revenue contribution from Fisdom in Q3 FY26 was approximately INR 29 crores, which is lower than the previous run-rate of INR 40 crores per quarter, falling short of the expected 3-4% contribution target. (1 missed, 1 met across 2 tracked commitments)
  > We are excited that there are tens more they will need, and we will continue building over the coming years.
- **[TREND] Brokers Becoming Wealth Platforms** (NEUTRAL, IN_PROGRESS): Management provided high-level details on the product roadmap (Mutual Funds, PMS, AIF, Insurance) but noted it is still early stage for specific differentiators or P&L impact details. (1 in progress across 1 tracked commitment)
  > The wealth offering is still in early days and we will talk more about this in the coming quarters.
- One-off adjustments related to long-term incentives are expected to be normalized by Q4 FY26. — target: Normalization (+3 more commitments) (NEUTRAL)
  > We think it is better to look at Adjusted EBITDA to determine the operating health of the company due to the one-off adjustments which will be normalised Q4 FY26 onwards.

### Business Model

- **[CATALYST] Leveraged Trading Product Expansion** (POSITIVE, Change: EXPANDING): The MTF book has seen explosive growth, increasing from ₹3,890 Mn to ₹16,683 Mn YoY, with active users nearly quadrupling as the company scales this high-margin lending product. (4 expanding across 2 engines)
  > I mean, this quarter it has grown quite well and is already contributing 6% to total revenue... historically it has grown is roughly INR600 crores we are adding almost every quarter.
- **[METRIC] Monthly Active Clients Percentage** (POSITIVE, Change: EXPANDING): While total NSE active clients for the industry and Groww declined YoY, Groww's market share of active clients actually expanded to 26.3%, indicating relative strength against competitors. (2 expanding)
  > NSE Active Clients... 25.6% (Q2 FY25) to 26.3% (Q2 FY26).
- **[METRIC] CAC and LTV Economics** (POSITIVE, Change: EXPANDING): Customer Acquisition Cost (CAC) improved dramatically, falling 33% quarter-on-quarter to approximately ₹900. (1 expanding)
  > Consequently, our CAC improved by 33% QoQ in this quarter to ~₹900.
- **[METRIC] Derivatives Revenue Concentration** (NEGATIVE, Change: CONTRACTING): Revenue share from Equity Derivatives has significantly contracted from 68% to 57% YoY, driven by regulatory changes like the 'True-to-label' circular which reduced revenue per order. (3 contracting across 1 engine)
  > Equity Derivatives ... 53% ... whilst grew ... 7% YoY
- **[METRIC] Interest Income Contribution Ratio** (POSITIVE, Change: EXPANDING): Lending products are expanding, specifically with the introduction of Loan Against Securities (LAS) on the company's own book, contributing to a 58% QoQ growth in disbursements. (1 expanding)
  > Disbursements by your in-house NBFC, viz. Groww CreditServ Technology, grew 58% QoQ... 36% of this was on account of Loan Against Securities (“LAS”), which was introduced in this quarter on our own book.
- **[PRINCIPLE] Client Activity Rate Focus** (POSITIVE, Change: EXPANDING): The company is seeing an improvement in the quality of its scale, with the ratio of transacting users to active users increasing from 60% to nearly 68% due to high engagement in IPOs and commodities. (1 expanding)
  > So roughly this number was more closer to 60% earlier. Now it's close to like 67%, 68% now. And that is primarily because last quarter, we talked about like gold, silver was doing well... because of the IPOs and stuff as well.
- **[PRINCIPLE] CAC Leverage and Viral Growth** (POSITIVE, Change: EXPANDING): The company is maintaining its organic growth engine with 80% of new users coming through non-paid channels, though it notes a recent increase in CAC that management expects to normalize annually. (1 stable, 1 expanding)
  > So customer acquisition cost when it comes to Groww customers using these services becomes almost zero for us.
- **[PRINCIPLE] Float Income Contribution** (NEUTRAL): The company earns 'Float' income, which is interest earned on customer cash balances held by the platform. — Float (6% revenue share)
  > Float ... 6%
- **[PRINCIPLE] Technology-Led Market Share Capture** (POSITIVE, Change: EXPANDING): The technology moat is being leveraged to drive down the 'cost to serve' through optimizations, even as order volumes increase, improving operational efficiency. (1 expanding, 1 stable)
  > we have launched Groww Lite using which all our customers can... see your positions and you can square them off. So if markets are going not in your favor, you are free to take actions from there.
- **[TREND] Derivatives Volume Structural Reset** (POSITIVE, Change: SHIFTED): The segment is undergoing a structural shift where active user counts have decreased (from 2M to 1.47M) due to new regulations, but the remaining 'top cohort' is performing larger transactions, leading to higher premium ADTO per user. (1 shifted)
  > basically, if you look at it what happened during after the regulations, lot of the customers who were doing smaller transactions actually stopped doing those transactions... we already had like more than almost 2 million customers who were active on F&O side. Today we have 1.47.
- **[TREND] India's Largest Broker by Clients** (POSITIVE, Change: EXPANDING): The network effect is strengthening as the company successfully migrates users from 'anchor' products like Mutual Funds into Stocks, ETFs, and IPOs, with 4.5% of incremental revenue now coming from new users. (1 expanding)
  > Welcome to Billionbrains Garage Ventures Limited, popularly known as Groww, Q3 FY '26 Earnings Conference Call... best known to investors and users as Groww.
- **[TREND] Beyond Brokerage Income Streams** (POSITIVE, Change: EXPANDING): The Stocks segment is expanding its revenue contribution, growing from 15% to 19% of the total income mix, supported by a 66% increase in average order value. (2 expanding, 1 shifted across 2 engines)

- **[TREND] Brokers Becoming Wealth Platforms** (NEUTRAL): The Wealth Management segment, following the acquisition of Fisdom, contributed Rs. 29 crores in revenue for the quarter and is a key focus for future diversification into high-net-worth services. — Wealth Management (Fisdom) (+1 more finding)
  > it seems like it's only INR 29 crores for this quarter... October is when we consolidated the acquisition. So there's a lot of work going on the wealth side from a strategy point of view.
- Cash Stocks trading is the second-largest segment, maintaining a steady share of the total income mix. — Stocks (18% revenue share) (+1 more finding) (NEUTRAL)
  > Stocks ... 18% ... whilst grew 24% ... YoY

### Future Growth

- **[CATALYST] Leveraged Trading Product Expansion** (POSITIVE, Trend: ACCELERATING): The MTF book is showing explosive growth, increasing from ₹3,890 Mn to ₹16,683 Mn YoY, with active users nearly quadrupling in the same period. (2 accelerating, 2 steady across 4 signals)
  > So, the way I think historically it has grown is roughly INR600 crores we are adding almost every quarter. I think this momentum is continuing from last three quarters... it has grown quite well and is already contributing 6% to total revenue.
- **[METRIC] Monthly Active Clients Percentage** (NEUTRAL, Trend: DECELERATING): Total transacting users reached 19 Mn in Q2 FY26, maintaining a steady growth trajectory of 27% YoY and 5% QoQ. (1 steady, 1 decelerating across 2 signals)
  > Total Transacting Users 20.4 Mn... +25% YoY
- **[METRIC] Interest Income Contribution Ratio** (POSITIVE, Trend: STEADY): The MTF product (part of the cash segment) is growing as a 'second product' for existing stock users, with pricing at 14.95% yield. (1 steady across 1 signal)
  > Our pricing is simple. It is 14.95%. Other than that, the growth rate I think it's not very -- we don't see competition from an MTF perspective specifically because it is a second product typically that customer is using.
- **[PRINCIPLE] Client Activity Rate Focus** (POSITIVE, Trend: ACCELERATING): The ratio of active users who are actually transacting has accelerated from approximately 60% to nearly 68% in the most recent quarter, driven by IPO activity and commodity interest. (1 accelerating across 1 signal)
  > So roughly this number was more closer to 60% earlier. Now it's close to like 67%, 68% now. And that is primarily because last quarter, we talked about like gold, silver was doing well... some of the customers got activated, reactivated... because of the IPOs.
- **[PRINCIPLE] CAC Leverage and Viral Growth** (NEUTRAL): Profitability is being boosted by 'operating leverage'—the ability to grow revenue faster than costs. The Adjusted EBITDA margin improved to 63.7% as the company became more efficient at serving and acquiring customers. — Adj. EBITDA Margin: +230bps YoY
  > Adj. EBITDA... ₹7,565 Mn | 63.7%... Q3 FY25... 61.4%
- **[PRINCIPLE] Technology-Led Market Share Capture** (NEUTRAL): Groww is gaining market share in the commodities segment, estimating its share to be in the double digits shortly after launch. (+1 more signal)
  > So hence our market share, we are not able to actually ascertain, but on a notional basis, we will be still at a double digit number at least.
- **[TREND] Derivatives Volume Structural Reset** (NEUTRAL): New regulations have caused a drop in the total number of active Futures & Options (F&O) traders, though the remaining traders are performing larger, more valuable transactions. — Active F&O Customers: Down from ~2 million
  > Because some of the -- we already had like more than almost 2 million customers who were active on F&O side. Today we have 1.47... lot of the customers who were doing smaller transactions actually stopped doing those transactions because number of expiries reduced.
- **[TREND] India's Largest Broker by Clients** (POSITIVE, Trend: STEADY): The company is successfully cross-selling, with 36% of new users now starting with SIPs (up 7pp YoY) and a growing share of ETF and IPO-first users. (2 steady across 2 signals)
  > Stocks... Retail Cash ADTO Market Share... Q3 FY25 21.6%... Q3 FY26 28.8%
- **[TREND] Beyond Brokerage Income Streams** (POSITIVE, Trend: ACCELERATING): LAS is scaling rapidly as a key part of the in-house NBFC strategy, accounting for 36% of the ₹1,444 Mn disbursements in Q2 FY26. (3 accelerating, 2 new trend across 5 signals, 2 leading indicators)
  > In Loans Against Securities, the book more than doubled, in Q3. Now, 9.7% of our balance sheet loan book is Loans Against Securities... up from 4.6% in the last quarter.
- **[TREND] Brokers Becoming Wealth Platforms** (POSITIVE, Trend: NEW_TREND): The strategy is shifting toward becoming a full wealth platform, specifically targeting 'affluent' customers through the integration of the Fisdom acquisition. (2 steady, 1 new trend across 3 signals, 2 leading indicators)
  > On the wealth side, again, we just recently, October is when we consolidated the acquisition. So there's a lot of work going on the wealth side from a strategy point of view, how we build it, how we are building both for the existing Groww customers and for a lot of affluent customers.

### Risk Assessment

- **[CATALYST] Leveraged Trading Product Expansion** (NEUTRAL, Risk: MODERATE): The risk is easing as MTF is becoming a core 'second product' for existing stock users, with management targeting a double-digit market share (up from current 3-4% of cash ADTO). (1 easing, 1 stable, 1 intensifying)
  > I mean, this quarter it has grown quite well and is already contributing 6% to total revenue... This depends a lot on volatility specific to some of the stocks which are there in MTF approved list.
- **[METRIC] Per-Client Revenue Generation** (POSITIVE, Risk: MODERATE): This risk has been resolved/reversed; revenue per broking order actually increased from ₹18.0 to ₹19.8 YoY due to higher order values and pricing changes. (1 resolved, 1 easing, 1 intensifying)
  > But if I look at 3Q numbers, that number has taken a dip to INR16 per order on the stock side.
- **[METRIC] CAC and LTV Economics** (POSITIVE, Risk: MODERATE): CAC (Customer Acquisition Cost) has intensified significantly, rising to ₹1,374 in H1 FY26 compared to ₹796 in H1 FY25, driven by aggressive branding spends during major events. (1 intensifying, 2 easing)
  > but when if you look at in last like 12 months to 18 months, market hasn't been that great. And hence the new acquisition in the industry level has actually slowed down.
- **[METRIC] Derivatives Revenue Concentration** (NEGATIVE, Risk: HIGH): The company's revenue is heavily dependent on two core products—Stocks and Equity Derivatives—which together account for 72% of total income, making earnings vulnerable to stock market volatility or specific regulatory changes in these segments. [CONCENTRATION]
  > Stocks & Equity Derivatives, our scaled products, whilst grew 24% and 7% YoY, respectively, their contribution to Total Income declined from 81% in Q3 last year to 72% in the current quarter
- **[METRIC] Interest Income Contribution Ratio** (NEGATIVE): Credit risk exposure is increasing as disbursements grew 58% QoQ, with a significant portion now coming from Loan Against Securities (LAS) on the company's own book. (3 intensifying)
  > Disbursements by your in-house NBFC... grew 58% QoQ... 36% of this was on account of Loan Against Securities (“LAS”), which was introduced in this quarter on our own book.
- **[PRINCIPLE] CAC Leverage and Viral Growth** (NEUTRAL, Risk: MODERATE): The risk is stable; while CAC can vary quarter-to-quarter based on market conditions, 80% of new users are still acquired organically, providing a significant buffer against rising marketing costs. (1 stable)
  > 14% of the growth in Total Customer Assets in Q3 was contributed by users acquired during the quarter.
- **[TREND] Derivatives Volume Structural Reset** (NEGATIVE, Risk: HIGH): The risk remains high as revenue from Derivatives saw a 10 percentage point drop in share YoY, and management explicitly cites 'true-to-label' and 'Equity Derivatives' regulations as the cause for a 9% YoY revenue decline. (1 intensifying, 2 stable, 1 high-severity)
  > Because some of the -- we already had like more than almost 2 million customers who were active on F&O side. Today we have 1.47.
- **[TREND] Beyond Brokerage Income Streams** (POSITIVE, Risk: LOW): Concentration risk is easing as the company successfully diversifies into interest-based income (MTF, LAS) and Mutual Funds. Derivatives share of income dropped from 68% to 57% YoY. (3 easing)
  > The book for our in-house NBFC (“GCS”) grew 7% QoQ to ~₹13,900 Mn.
- **[TREND] Brokers Becoming Wealth Platforms** (NEGATIVE, Risk: MODERATE): Execution risk is emerging as a key focus following the 100% acquisition of Fisdom in October 2025, which will impact the P&L starting Q3 FY26. (2 emerging, 1 intensifying, 1 stable)
  > I mean, there's some time with still a lot of integrations are happening. And we will, it's very small both ways as compared to the overall P&L of Groww.
- The risk remains high but is being managed through significant revenue growth that outpaces fixed cost increases. Management confirmed that 90% of costs are fixed, but these are only expected to grow by 10-20% annually, allowing for EBITDA margin expansion as revenue scales. (1 stable, 1 high-severity) (NEGATIVE, Risk: MODERATE)
  > And our variable cost is roughly like - 10% is roughly the variable cost. Rest all is more on the fixed nature.

### Scenario Analysis

- 4 positive impacts identified (POSITIVE)
  > So for which we have launched Groww Lite using which all our customers can, as the name suggests, it's a very lighter version of Groww. You can't do many other things, but you can see your positions and you can square them off. So if markets are going not in your favor, you are free to take actions 
- 5 positive impacts identified; 1 negative impact identified (POSITIVE)
  > but when if you look at in last 12 months to 18 months, market hasn't been that great. And hence the new acquisition in the industry level has actually slowed down. So this is not a good time to actually invest more. But this is a good time to actually probably do more optimizations and focus more o
