Unlocking the Secrets of Stock Dilution & Institutional Discounts 📈

When a company needs to raise funds for expansion, debt reduction, or other corporate purposes, issuing new shares to institutions is a common method. Unlike a public offering where shares are offered to retail investors, these placements are tailored for institutional investors. The price offered to them is typically lower than the Current Market Price (CMP) to make the large investment attractive and compensate for factors like potential lock-in periods and the extensive due diligence they conduct.

For instance, if a company’s CMP is ₹100, institutional investors might be offered shares at ₹85 or ₹90. This isn’t arbitrary; it’s governed by stringent SEBI regulations to ensure fairness and transparency.

Understanding SEBI Regulations on Discount and Dilution

The SEBI Pricing Formula: The 90% VWAP Rule 📏

For preferential allotments and QIPs, SEBI mandates a specific pricing formula to determine the minimum issue price. This formula ensures that the discount offered is within acceptable limits.

This “Volume Weighted Average Price” (VWAP) is a critical indicator. It represents the average price at which a stock has traded over a specified period, weighted by volume. This means that trades with higher volume have a greater impact on the average price. By taking the higher of the two periods (2 weeks or 6 months), SEBI ensures that companies cannot exploit short-term price fluctuations to offer an unfairly low price.

What VWAP Means in Simple Terms:

Imagine Reliance Industries wants to issue shares to institutions. SEBI will look at two VWAP values:

• **VWAP (Last 10 Trading Days):** The average price weighted by the volume traded over the last two weeks.
• **VWAP (Last 90 Trading Days):** The average price weighted by the volume traded over the last six months.

The company must then take the **higher** of these two VWAP figures. Let’s say the 6-month VWAP is ₹1500 and the 2-week VWAP is ₹1450. The higher is ₹1500. The minimum issue price for the preferential allotment will be 90% of ₹1500, which is ₹1350.

This means that even if the Current Market Price (CMP) is, for instance, ₹1400, the company cannot issue shares below ₹1350 if the calculated VWAP floor price is ₹1350. The maximum allowed discount in this scenario would be 10% (1500 – 1350 = 150; 150/1500 = 10%). Any discount greater than this usually requires special approvals, including shareholder consent through an Extraordinary General Meeting (EGM).

Can Companies Dilute More Than 15% or Even 50%?

There isn’t a hard limit set by SEBI on the maximum percentage of dilution. Instead, the focus is on transparency, shareholder approval, and the rationale behind such large issuances. Any major dilution requires:

• Board Approval: The company’s board of directors must approve the dilution.
• Shareholder Approval: A special resolution must be passed by shareholders, often requiring a 75% majority.
• SEBI Guidelines Adherence: Strict compliance with SEBI’s Issue of Capital and Disclosure Requirements (ICDR) Regulations, including proper pricing, disclosures, and lock-in periods for the newly issued shares.

Such massive dilution events (e.g., >50%) are rare and usually occur under specific circumstances, such as:

• The company is facing severe financial distress and urgently needs capital to survive.
• Strategic mergers or acquisitions where new shares are issued as consideration.
• Major business expansions requiring unprecedented capital infusion.

Impact on Promoter Shareholding Percentage: A Key Consequence of Dilution

Share dilution increases the total number of outstanding shares. If the existing shareholders, including promoters, do not participate in the new share issuance to maintain their proportionate stake, their percentage of ownership in the company will naturally decrease.

Promoter Dilution Table: From 5% to 50% Dilution

Let’s illustrate this with an example. Assume the following before dilution:

• Current Market Price (CMP) = ₹100
• Promoter holds = 48 crore shares
• Total shares before dilution = 100 crore shares
• New shares issued to institutions at ₹85 (a 15% discount to CMP)

The table below shows how the promoter’s percentage holding would change as dilution increases, assuming promoters do NOT participate in the new share issuance:

Note: Dilution % here refers to the percentage increase in the total number of shares outstanding relative to the original shares, not the price discount.

Real-Time Example: Reliance Industries and SEBI’s 90% VWAP Rule

Let’s apply SEBI’s pricing guidelines to a real-world scenario using Reliance Industries Limited (RIL) data. We’ll use approximate figures for illustrative purposes.

Current Scenario for Reliance Industries (Approximate Data as of July 2025)

• Current Market Price (CMP): ₹1,670
• 6-Month VWAP: ₹1,357 (This is the volume-weighted average price over the last 6 months, as provided in the prompt. Note that this is significantly lower than CMP, implying the stock has risen sharply recently from its 6-month average.)
• Total Shares Outstanding: As per recent reports and financial data platforms like Stock Analysis, Reliance Industries has approximately 6.7663 Billion (676.63 Crore) shares outstanding. This figure is dynamic and can be checked on official exchange websites (NSE/BSE) or reputable financial data providers.

Calculating the Maximum Discount and Offer Price:

As per SEBI’s 90% VWAP rule, the minimum issue price for a preferential allotment or QIP will be based on the higher of the 2-week VWAP or 6-month VWAP.

Given the 6-month VWAP of ₹1,357, this is likely to be the higher of the two relevant VWAPs for a company like Reliance if its stock has seen recent upward momentum, causing the CMP to be significantly higher than its longer-term average.

• Higher VWAP (for calculation): ₹1,357
• SEBI Minimum Issue Price (90% of VWAP): $0.90 \times \text{₹1,357} = \text{₹1,221.30}$

Where to Find “Total Shares Outstanding” and VWAP Data?

While quarterly reports and investor presentations often provide a wealth of financial information, “Total Shares Outstanding” might not always be explicitly highlighted in every section. However, this information is consistently available from official and reliable sources:

• Stock Exchanges (NSE/BSE): Companies are legally mandated to file their shareholding patterns and capital structure details with the stock exchanges regularly. You can find this data by searching for the company on the NSE India or BSE India websites under their “Shareholding Pattern” or “Financials” sections. This is the most accurate and up-to-date source.
• Financial Data Portals: Reputable financial websites (e.g., Moneycontrol, Investing.com, Stock Analysis, Yahoo Finance, Screener.in) aggregate data directly from stock exchanges and company filings. They typically list “Shares Outstanding” under “Share Statistics” or “Capital Structure.”
• Annual Reports & Quarterly Results: While a specific “Capital Structure” section might not always be present, look for it in the “Notes to Accounts,” “Balance Sheet” (under Share Capital), or sections detailing “Earnings Per Share (EPS)” calculation.

For VWAP data, you’ll often find it on advanced charting platforms (like TradingView with a VWAP indicator), institutional terminals (Bloomberg, Reuters), or by performing manual calculations from historical daily price and volume data available on exchange websites.

Important Note: The “Quter-Data-Relaince.pdf” you mentioned might not have explicitly stated “Capital Structure” as a heading, but the total shares outstanding figure of 676.63 Crores aligns with public records for Reliance Industries, indicating that this data is derived from their official filings with the exchanges.

Python Script for VWAP and Offer Price Calculation

To help you quickly calculate the approximate 6-month VWAP and the maximum offer price based on a given CMP and percentage drop from VWAP, here’s a Python script.

def calculate_vwap_and_offer(cmp, drop_percent, discount_percent=10):

# For simplicity, let's assume 2-week VWAP is also around 1357 or lower
calculate_offer_price_direct(cmp=1670, vwap_6m=1357, vwap_2w=1300)

            

This script helps visualize the relationship between CMP, VWAP, and the SEBI-mandated offer price, providing clarity on how the discount mechanism works. The second example demonstrates a scenario where the CMP is actually *higher* than the 6-month VWAP, implying the stock has performed well recently. In such cases, the SEBI minimum issue price would still be calculated off the VWAP, leading to a significant discount from CMP, which is highly attractive for institutions.

Conclusion: Navigating the Complexities of Stock Dilution

SEBI’s regulations are designed to strike a balance: allowing companies to raise necessary capital efficiently from institutions while simultaneously protecting existing shareholders from unfair pricing and excessive, unapproved dilution. Promoters’ shareholding percentage will almost always decline unless they make a proportionate investment in the new issue, which is often not allowed or practical in QIPs.

As an investor, keeping an eye on a company’s shareholding pattern, the nature of its capital-raising activities, and adherence to SEBI norms can provide valuable insights into its financial health and management’s commitment to shareholder interests. Always check official company filings and reliable financial news sources for the most accurate and up-to-date information.
