Rights issues and dilution: understanding ownership on the NSE

Why this matters

Rights issues move the goalposts for your ownership and the value you hold in a stock. If you participate, you can maintain your stake; if you skip, your percentage ownership can fall even if the company does not perform poorly. Reading the offer terms carefully helps you decide whether to fund the new shares or to trade your rights instead.

The concept

A rights issue is a new share sale to existing shareholders at a price typically below the current market price. Each shareholder receives rights based on their current holding, and these rights can be used to buy new shares or sold on the market if the issuer allows it. Key terms you need to know:

• rights: the entitlement to buy a certain number of new shares at a discount
• subscription price: the price you pay per new share
• ex-rights date: the date the stock starts trading without the rights attached
• dilution: the reduction in a shareholder’s ownership percentage if they do not participate
• theoretical ex-rights price TERP: the price per share after the rights issue if all rights are exercised and cash is added to the company
• oversubscription: when demand from shareholders exceeds the number of new shares offered

How it works on the NSE

On the Nairobi Securities Exchange a rights issue is typically offered to existing shareholders of record. In many cases, the issuer may allow trading of the rights on the open market for a period, enabling investors to sell rights if they don’t plan to participate. After the offer closes and new shares are issued, the total number of shares increases and the market price often rebalances toward the TERP. Your ownership percentage shifts depending on whether you exercise, trade, or ignore the rights:

• exercise all rights: you keep your proportional stake, but you invest cash to buy the new shares
• trade the rights: you lock in value from the rights without putting up additional capital
• ignore the rights: your relative stake falls because the company issues new shares to others while you hold the same number of shares

Worked example

Assume a company with 100,000 shares outstanding and a market price of 20 per share before the rights issue. The rights offer is 1 new share for every 4 held, at a subscription price of 12 per new share. This means 25,000 new shares will be issued and total shares after the issue will be 125,000.

• Pre-issue value: 100,000 shares × 20 = 2,000,000
• New money raised: 25,000 × 12 = 300,000
• Post-issue value basis (TERP): (2,000,000 + 300,000) / 125,000 = 2,300,000 / 125,000 = 18.4 per share
• If you do nothing: you still own 100,000 shares, but at a post-issue price of 18.4, your holdings are worth 1,840,000. Your ownership stake falls to 100,000 / 125,000 = 80% of the company.
• If you participate fully: you subscribe for all 25,000 new shares at 12, paying 300,000. After the issue, you own 125,000 shares. The value of your stake is 125,000 × 18.4 = 2,300,000, which equals your total cash outlay (100,000 shares on day one valued at 18.4 each, plus 25,000 new shares bought at 12 discount but revalued to the same TERP). Your ownership percentage remains 100,000 / 125,000 = 80% if you consider ownership against the updated tally, but you actually hold all the shares now, so your effective market exposure mirrors the post-issue structure.
• If you participate partially: suppose you subscribe to 12,500 of the new shares. Your new total shares = 112,500. The TERP still roughly applies, and your ownership percentage becomes 112,500 / 125,000 if you hold all post-issue shares. The key takeaway is that partial participation helps preserve a larger fraction of your stake than skipping completely, but your exact economics depend on how many new shares you take and the subsequent price movements.
• The takeaway on dilution: the mere existence of new shares dilutes ownership for those who don’t participate. The more you participate, the closer your percentage stays to the pre-issue level; if you purely hold without adding capital, your stake shrinks because more shares exist in the company than before.

Common mistakes

• Assuming the rights are free money. Rights have real value only if you exercise or trade them; the discounted price is the kicker, not a windfall.
• Ignoring the ex-rights date. If you buy on or after this date, you miss the entitlement and cannot participate in the offer.
• Failing to compare the subscription price to the market price. If the rights price is not compelling versus the current price after the rights launch, you may not want to participate.
• Not calculating ownership after the issue. It’s easy to be confused about percentages when the total share count changes.
• Overlooking tax and transaction costs. These affect the net benefit of participating or trading the rights.

Your checklist

• Read the offer circular and identify the subscription ratio and the price per new share.
• Note the record date and ex-rights date so you don’t miss entitlement.
• Compute the TERP to gauge the post-issue price direction.
• Decide whether to exercise, trade, or ignore based on your current holdings and cash position.
• Check for oversubscription rules and allocation if you plan to participate more than your entitlement.
• Factor in fees and potential tax implications before acting.

FAQ

• What is dilution in this context? Dilution means your ownership percentage decreases because more shares are outstanding without a corresponding increase in your number of shares, unless you participate and buy the new shares.
• Should I always participate in a rights issue? Not always. If the subscription price is close to or above the market price after the rights, or you lack cash, selling the rights or skipping may be better. Your decision should hinge on your cash position and your view of the issuer’s prospects.
• Can rights be traded on the NSE? Yes, in many cases rights trade on the market for a limited window, giving you a way to monetize the entitlement if you don’t want to buy more shares.
