The Role of Underwriters in Indian IPOs: How They Influence Pricing, Allocation, and Investor Returns

1. Definition and Core Responsibilities of Underwriters in the Indian Market

In an Indian Initial Public Offering (IPO), the underwriter (also called the lead manager or book‑runner) is a merchant‑banking institution appointed by the issuing company to:

• Structure the offering: Decide the issue size, type of securities, and timeline.
• Conduct due‑diligence: Verify the issuer’s financials, legal compliance, and disclosures.
• Set the price band and manage book‑building: Translate market sentiment into a price range that balances issuer proceeds with investor appetite.
• Allocate shares: Distribute the issue among institutional investors (IIs), qualified institutional buyers (QIBs), and retail investors (RIs) as per SEBI guidelines.
• Stabilise the market post‑listing: Exercise the overallotment (greenshoe) option, if any, to curb excessive volatility.

In India, underwriters are typically large investment banks—e.g., Kotak Mahindra Capital, JM Financial, Axis Capital, and international houses such as Goldman Sachs and Morgan Stanley—often forming a syndicate to share risk.

2. The Underwriting Process: Due Diligence, Price Band Setting, and Book Building

2.1 Due Diligence

Due diligence is the backbone of a credible IPO. Underwriters examine:

• Audited financial statements (last 3‑5 years).
• Tax compliance and pending litigation.
• Corporate governance practices and promoter background.
• Industry dynamics, competitive positioning, and growth projections.
• Regulatory clearances, especially for sectors like fintech, e‑commerce, and pharmaceuticals.

The findings are compiled in the “Red Herring Prospectus (RHP)” and the “Due Diligence Report” submitted to SEBI.

2.2 Price Band Setting

After due diligence, underwriters propose a tentative price band—usually a 10‑15% range around the estimated fair value. The band is influenced by:

• Comparable company multiples (EV/EBITDA, P/E).
• Growth outlook and cash‑flow generation.
• Recent IPO performance in the same sector.
• Investor sentiment measured through pre‑IPO roadshows.

For instance, Zomato’s IPO (2021) opened with a price band of INR 2,650‑2,950 per share, reflecting a 30‑35% premium over its FY‑2020 earnings.

2.3 Book Building

Book building is an auction‑like process where investors submit bids within the price band. The underwriter’s responsibilities include:

• Collecting and aggregating bids from QIBs, FIIs, and retail investors.
• Maintaining a “book‑run” that tracks demand at each price point.
• Ensuring confidentiality and fairness—no bidder gets preferential treatment.

The final issue price (cut‑off price) is set where demand meets supply, often after a “price discovery” meeting with the issuer.

3. How Underwriters Determine IPO Pricing and the Impact on Investor Returns

Pricing is a balancing act:

• Issuer’s objective: Maximise capital raised while preserving a reasonable post‑listing valuation.
• Investor’s objective: Secure a discount to the expected trading price for upside.

Underwriters use quantitative models (DCF, relative valuation) and qualitative inputs (brand strength, market narrative). The final price is typically set at the highest price where the total demand equals the issue size, known as the “price‑discovery point.”

3.1 Pricing Scenarios

Scenario	Underwriter Action	Typical Impact on Retail Investors
Undervaluation (price set too low)	Increase overallotment to capture excess demand.	Strong first‑day gains; high resale demand.
Overvaluation (price set too high)	Exercise greenshoe to stabilise; may lead to price drop.	Potential negative returns on listing day.
Balanced pricing	Minimal overallotment; stable post‑listing price.	Modest but sustainable returns.

3.2 Real‑World Impact

Paytm’s 2021 IPO was priced at INR 2,150‑2,350, a 30% premium over its FY‑2020 earnings. The stock fell 13% on listing day, illustrating how an aggressive price band can erode retail returns.

4. Allocation Mechanisms: Institutional vs Retail, and the Underwriter’s Influence on the Retail Allocation Ratio

SEBI mandates a minimum 35% allocation to retail investors for IPOs with a face value of INR 10 or more. However, the actual ratio is a product of underwriter discretion, demand dynamics, and the issuer’s preferences.

4.1 Institutional Allocation

• QIBs and FIIs receive the bulk of the issue (typically 55‑65%).
• Allocation is based on bid size, historical participation, and strategic relationships.

4.2 Retail Allocation

• Retail investors can bid for a maximum of 2 lakh shares (INR 2 lakh worth) per applicant.
• Underwriters use a “lot‑size” methodology—e.g., Zomato’s lot size was 2 lakh shares—to standardise allocations.
• When retail demand exceeds supply, a lottery system is employed, overseen by the registrar (e.g., Karvy, Link). The underwriter’s role is to submit the final retail quota to the registrar.

4.3 Underwriter Influence

While SEBI caps the minimum retail share, underwriters can negotiate a higher retail quota with the issuer. A higher retail allocation often signals confidence in broad market participation and can improve the IPO’s perception among small investors.

Example: Nykaa’s IPO (2021) had a 50% retail allocation—well above the statutory minimum—thanks to a proactive stance by its lead manager, Axis Capital, which advocated for a broader investor base.

5. The Overallotment (Greenshoe) Option and Its Purpose

The overallotment option, commonly called the “greenshoe,” permits the underwriter to issue up to 15% additional shares beyond the base issue size.

• Stabilisation: If the share price falls below the issue price, the underwriter can buy back shares in the open market to support the price.
• Liquidity provision: The extra shares increase float, aiding price discovery.
• Risk management: Underwriters can exercise the option if demand exceeds the base issue, thereby earning additional underwriting fees.

In Zomato’s IPO, the greenshoe was fully exercised, adding 4.2 million shares (≈15% of the base issue) and helping the stock close 7% higher on the first trading day.

6. SEBI Regulations Governing Underwriting Activities, Recent Reforms, and Compliance Requirements

Key regulatory provisions:

• SEBI (Issue of Capital and Disclosure Requirements) Regulations, 2022 (ICDR): Defines underwriting standards, minimum capital adequacy for underwriters (INR 5 crore), and conflict‑of‑interest disclosures.
• Underwriter’s Liability: Underwriters must guarantee the issue size; failure to subscribe results in financial liability.
• Retail Allocation Mandate: Minimum 35% for face value ≥ INR 10; 75% for face value < INR 10.
• Overallotment Clause: Must be disclosed in the prospectus with a clear timeline (up to 30 days post‑listing).

6.1 Recent Reforms (2023‑2024)

• Enhanced Disclosure of Underwriter Fees: SEBI now requires a detailed breakdown of fixed and variable fees, promoting transparency.
• Limitation on Multiple Underwriting Mandates: An underwriter cannot act as lead manager for more than three IPOs in a six‑month window to avoid concentration risk.
• Digital Bidding Integration: Underwriters must support the e‑Bidding platform (NSDL/CMAT) and ensure real‑time bid validation.

6.2 Compliance Checklist for Underwriters

Requirement	Compliance Action
Capital Adequacy	Maintain minimum net worth of INR 5 crore; submit KYC to SEBI annually.
Conflict‑of‑Interest Disclosure	File Form‑A with details of any related‑party transactions.
Prospectus Accuracy	Legal team reviews RHP; underwriter signs off on risk factors.
Post‑Listing Stabilisation	Maintain a “stabilisation fund” (usually 5% of issue size) to support greenshoe exercises.

• Greenshoe: Not exercised; overallotment left unutilised.
• Outcome: Listing day close at INR 1,870 (‑13%); retail oversubscription ≈41×.
• Underwriter’s Role: Despite strong demand, the aggressive pricing and limited retail quota contributed to a negative first‑day performance, highlighting the risk of over‑optimistic valuation.

8. How Investors Can Assess the Reputation and Track Record of Underwriters Before Applying

Retail investors can use the following criteria to gauge an underwriter’s credibility:

• Historical IPO Success Rate: Look at the percentage of IPOs where the issue price closed higher on the first day.
• Retail Allocation Consistency: Underwriters with a track record of ≥45% retail allocation often favour small investors.
• Stabilisation Record: Review whether the underwriter exercised the greenshoe efficiently in past issues.
• Regulatory Standing: Check SEBI’s “list of disqualified entities” to ensure the underwriter is not under any sanction.
• Analyst Reports: Brokerage houses often publish “Underwriter Scorecards” that rank managers on pricing accuracy and allocation fairness.

For example, a quick scan of the 2021‑2022 IPO season shows that JM Financial had a 78% first‑day positive return rate, whereas some newer entrants had a 50% negative return rate.

9. Practical Tips for Retail Investors to Navigate Underwriter‑Driven Dynamics When Applying for IPOs

1. Know the Lead Manager(s): Identify the underwriters from the prospectus; prioritize IPOs where the lead manager has a strong retail‑allocation record.
2. Bid at the Upper End of the Price Band: If you are confident about the company’s fundamentals, placing a bid at the top of the band can improve chances of allocation, especially when the issue is oversubscribed.
3. Apply Through Multiple Platforms: Use both your demat broker and the e‑Bidding portal (NSDL/CMAT) to avoid technical glitches during peak bidding windows.
4. Limit the Number of Applications: SEBI caps the total number of IPO applications per PAN (currently 10). Prioritise high‑conviction IPOs to avoid “allocation dilution.”
5. Monitor Greenshoe Utilisation: If the underwriter exercises the greenshoe, the post‑listing price may stabilise, reducing the risk of a sharp dip.
6. Check the Retail Allocation Ratio: Prospectuses disclose the exact retail quota; a higher
