Editor’s note: This is an educational explainer about how rights issues generally work on the Nairobi Securities Exchange. It is general information, not investment advice, and does not describe any specific current event, company, or security.

A shareholder who does nothing during a rights issue window does not simply keep the status quo. Depending on how the entitlement is structured, inaction can mean an asset with real market value simply lapses, unclaimed, at the close of trading on a fixed date. Understanding why requires looking at the mechanics the Nairobi Securities Exchange (NSE) and Kenya’s Capital Markets Authority (CMA) put in place to move a rights issue from announcement to settlement, and at the little-known secondary market where the rights themselves, not just the underlying shares, change hands.

How a Rights Issue Moves Through the NSE

A rights issue begins when a listed company seeks CMA approval to raise additional capital by offering new shares to existing shareholders in proportion to their current holdings, commonly expressed as a ratio such as one new share for every five already held. Once approval is granted, the company fixes a “books closure” or record date: everyone registered as a shareholder at that point becomes entitled to subscribe. The NSE and the Central Depository and Settlement Corporation (CDSC) then credit each eligible shareholder’s account with provisional allotment letters or, in the dematerialised environment now standard at the NSE, electronic rights entries reflecting their entitlement.

From there, a defined subscription period opens, typically several weeks, during which shareholders can take up all or part of their entitlement by paying the subscription price, decline the offer entirely, or, where the rights are renounceable, sell the entitlement to someone else. The NSE publishes the timetable for these steps, including the last trading day for the rights and the closing date for acceptance, so that brokers and the depository can process instructions in sequence rather than in a rush at the deadline.

Why Renounceability Matters, and How Rights Get Traded

Not every rights issue is renounceable, but where a company structures it that way, the entitlement itself becomes a tradable instrument for a limited window on the exchange, separate from the parent company’s ordinary shares. This exists because a shareholder’s decision not to inject fresh capital should not have to mean forfeiting the underlying value of the entitlement outright. If the subscription price sits meaningfully below the market price of the existing shares, the right to buy at that discount carries value in its own right, and a shareholder who cannot or does not want to participate can instead sell that entitlement to another investor through their stockbroker.

The rights typically trade under a distinct code on the NSE’s board for a defined stretch of the subscription period, usually closing a few days before the full offer itself closes, to leave time for settlement and for the buyer to exercise the acquired rights before the final deadline. Pricing in this secondary rights market tends to track the gap between the subscription price and the ruling market price of the ordinary shares, adjusted for the time remaining and for how confident the market is that the issue will complete as planned. Brokers executing these trades follow the same order-matching and settlement infrastructure used for ordinary equity trading, just against a different, shorter-lived instrument.

What Happens at Expiry

Whether a shareholder subscribes directly or acquires rights on the secondary market, the final step is the same: payment must reach the receiving bank or registrar, and instructions must be lodged with the broker or registrar before the acceptance deadline, after which allotment of the new shares is finalised and they are credited to CDSC accounts ahead of listing. Any renounceable rights that were never sold and never exercised by that final cut-off simply lapse. They are not automatically converted to cash or returned to the shareholder in any other form; the value, if any existed, is forfeited.

This is precisely why the NSE and brokers publicise the timetable so heavily around a rights issue. The mechanism gives shareholders three distinct choices, subscribe, sell, or let it lapse, and only the first two preserve any value tied to the entitlement. The procedural scaffolding, from CMA approval through CDSC crediting to final allotment, exists to make sure each of those choices can actually be exercised within the stated window, not to compel any particular one.
