Down Rounds and Dilution: The Legal Mechanics Nobody Explains

Every founder knows the word dilution. Far fewer can say what actually happens — legally, step by step — when a company raises at a lower price than the last round and an investor's anti-dilution clause wakes up. The vocabulary of that moment is American: ratchets, weighted averages, conversion-price adjustments. The machinery available to perform it in Pakistan is not. A Pakistani private company operates under the Companies Act, 2017, where new shares travel through defined statutory steps and a "conversion price" is not a thing the share register knows about. This briefing, current as of July 2026, explains both layers — the contractual promise and the statutory performance — because a clause that cannot be performed is a dispute, not a protection.

Dilution is a legal event before it is arithmetic

Start with the baseline every scenario runs through. Under section 83 of the Companies Act, 2017, when a company increases its capital by issuing further shares, those shares are first offered to existing members in proportion to their holdings. Dilution in the economic sense therefore never simply happens to a shareholder of a Pakistani company; it happens after a legal fork at which they were entitled to subscribe and maintain their percentage, or the company obtained the authority required to place the shares elsewhere [MECHANISM UNDER THE COMPANIES (FURTHER ISSUE OF SHARES) REGULATIONS, 2020 FOR PRIVATE COMPANIES — TO BE VERIFIED BY REVIEWING LAWYER]. Two consequences follow. First, every funding round — up or down — requires the pre-emption position to be cleared: waivers gathered or the resolution passed, before allotment. Second, an existing investor's most basic anti-dilution protection is not a clause at all; it is the statute, plus a cheque. Everything contractual is built on top of that floor.

What the clauses promise

Anti-dilution provisions are contract terms, enforceable between their parties under the Contract Act, 1872, and they answer one question: if the company later sells shares cheaper than the investor paid, how is the investor compensated? Full ratchet gives the harshest answer — treat the investor as if they had invested at the new, lower price, however few shares were actually sold at it. Broad-based weighted average gives the mainstream answer — adjust the investor's effective price by a formula that weighs the old price against the new money's size, so a small cheap round produces a small adjustment. The difference between the two formulas is not technical. In a down round it is frequently the largest single transfer of value between founders and investors in the company's life, and it was decided in one line of a term sheet signed years earlier — usually alongside the other terms discussed in our fundraising and investment practice.

The scenario, in numbers

The table below is illustrative only. It assumes a company with 8,000,000 founder shares; a seed investor who paid Rs 200,000,000 for 2,000,000 shares at Rs 100 per share; and a later down round in which a new investor puts in Rs 100,000,000 at Rs 40 per share (2,500,000 new shares). For simplicity it prices the new investor's shares at Rs 40 in every scenario and ignores the ESOP pool. These are invented numbers chosen for clean arithmetic — not market data.

Scenario	Founders	Seed investor	New investor	Extra shares issued to seed investor
Before the down round	80.0%	20.0%	—	—
Down round, no anti-dilution	64.0%	16.0%	20.0%	0
Broad-based weighted average	62.6%	17.8%	19.6%	~272,700
Full ratchet	51.6%	32.3%	16.1%	3,000,000

Read the founder column. The down round itself costs the founders sixteen points. The weighted-average adjustment costs them roughly one and a half points more — real, but survivable. The full ratchet costs them a further eleven points beyond the unprotected case, taking founders from 80% to barely half the company, because it reprices the seed investor's entire Rs 200,000,000 at Rs 40. Note also the new investor's column: the anti-dilution shares dilute them too, which is why incoming investors in a down round routinely demand that existing investors waive or soften their protections as a condition of the new money.

How the promise is performed — and where it snags

Now the part the US templates skip. In Delaware, anti-dilution operates by adjusting the price at which preferred stock converts into common: no new shares are issued until conversion, so the adjustment is a formula in a charter. A Pakistani private company has no such native mechanism — the register of members under the Companies Act, 2017 records shares, not conversion formulas. The protection is therefore usually performed by issuing additional shares to the protected investor, and each route to doing so has statutory friction.

Issuing the make-whole shares for fresh consideration at face value works only if face value is low enough; the Companies Act, 2017 restricts issuing shares at a discount to face value, so a company whose shares carry a Rs 100 face value cannot simply issue at Rs 10 to hit the formula [DISCOUNT RESTRICTIONS AND CONDITIONS — TO BE VERIFIED BY REVIEWING LAWYER]. This is a strong argument, made at incorporation, for a nominal face value. Issuing them as a capitalisation of reserves runs into the opposite problem: a bonus issue ordinarily benefits all members proportionately, not one investor selectively [SELECTIVE CAPITALISATION — TO BE VERIFIED BY REVIEWING LAWYER]. And every route runs back through section 83: the anti-dilution issue is itself a further issue of shares, needing the same pre-emption clearance as the round that triggered it. Where the protected investor is foreign, add the exchange-control layer — shares issued to a non-resident for nominal or no fresh remittance sit awkwardly with the Foreign Exchange Regulation Act, 1947 reporting framework, and the route should be agreed with the authorised dealer in advance [TREATMENT OF ANTI-DILUTION ISSUES TO NON-RESIDENTS — TO BE VERIFIED BY REVIEWING LAWYER]. The drafting lesson: an anti-dilution clause for a Pakistani company must state its performance mechanics — who resolves what, at what price, within what period — or it is an economics term with no engineering.

The down round itself: process is the protection

A down round is also a governance event, and the legal exposure runs in all directions. Directors approving an issue of shares at a price that transfers value between shareholder groups are exercising Companies Act, 2017 powers subject to their duties to act in good faith in the company's interest, and a disgruntled diluted shareholder's challenge will be aimed at process: was the price tested, were alternatives explored, was the pre-emption offer genuine? The clean down round therefore documents its necessity — the fundraising efforts that failed, the runway arithmetic — offers existing shareholders the chance to participate on the same terms, obtains any class consents the articles require for varying preferential rights [VARIATION OF CLASS RIGHTS PROCEDURE — TO BE VERIFIED BY REVIEWING LAWYER], and puts the anti-dilution waivers or adjustments in writing before allotment, not after. Pay-to-play mechanisms — protection available only to investors who join the new round — are contractual and negotiable under the Contract Act, 1872, and are often the fairest bridge between old and new money.

What this means for you

At the first round, not the down round, is when this is decided: negotiate broad-based weighted average rather than full ratchet, set a nominal face value so future adjustments are performable, and insist the clause specifies its own mechanics under the Companies Act, 2017. If a down round is approaching, sequence it deliberately — pre-emption offers, class consents, anti-dilution calculations agreed in writing, then allotment — and document why the price is what it is. If you hold protection, understand that the incoming investor will likely ask you to soften it, and decide your answer before you are asked. And if your cap table already contains a full ratchet, treat it as a live liability to be renegotiated in calm weather. Dilution is arithmetic; a down round is law. The companies that come through cleanly are the ones that treated it that way.
