From Cover to Cash Flow: A Prospectus Checklist for UK New Issues

UK equity markets are hoping for a busier IPO window in 2026. That will bring a familiar ritual: a glossy announcement, a roadshow, a spread of banker language and a prospectus that few private investors will read from cover to cover. The temptation is to rely on the headline valuation and the name on the ticket. The better approach is to treat the prospectus as a set of answers to specific questions. If those answers are thin, the listing is not ready for your money.

1. Is the revenue repeatable, or merely recent?

Start with the quality of the top line. A prospectus will show growth, but growth can come from acquisitions, price rises, one-off contracts or a market that is temporarily hot. Look for organic growth separately from acquired growth. Check whether revenue is recurring, contracted or dependent on annual renewals. Read the segment disclosures and the customer case studies with a sceptical eye. A company that claims a large addressable market but cannot show sticky revenue is asking you to pay for a story.

2. How much depends on a handful of customers?

Customer concentration is one of the most useful disclosures in any new issue document. If the top five customers account for a large share of revenue, ask about contract length, renewal terms and what happens if one leaves. A long-term contract is not automatically safe if the customer has pricing power or can insource the work. Look for disclosure on customer churn and net revenue retention where it is available. A business that loses its largest customer in year two was never worth the listing multiple.

3. What exactly will the proceeds do?

The use of proceeds section separates growth capital from an exit for existing owners. Money used to repay debt, pay a dividend or buy out private equity shareholders is not the same as money used to build a factory, hire engineers or fund working capital. All three can be legitimate, but they carry different risks. Check how much of the proceeds goes to the company and how much goes to selling shareholders. If the main purpose is to let early investors cash out, the listing is partly a liquidity event, not a pure growth story.

4. Who is selling, and when can they sell again?

Lock-ups are meant to align insiders with new investors, but they vary in length and scope. Read who is subject to a lock-up, for how long, and whether there are exceptions. A short lock-up with a large overhang can weigh on the shares soon after listing. Watch for selling shareholders who retain a controlling stake and for any relationship agreements that give them influence after the IPO. The market can absorb a lot, but it dislikes surprises.

5. What is hiding inside adjusted profit?

Adjusted EBITDA is a useful measure, but it is not a statutory profit figure. Read the reconciliation to reported profit carefully. Large add-backs for share-based payments, restructuring, acquisition costs or exceptional items can flatter the picture. Ask whether those costs are genuinely one-off or simply part of running the business. Then look at cash conversion. A company that reports strong adjusted profit but weak operating cash flow is telling you something important about working capital, capital expenditure or the quality of its earnings.

6. Does the working capital story add up?

The prospectus should include a working capital statement. Read it alongside the cash flow forecast and the debt facilities. Does the company have enough headroom for the next twelve months? Are supplier terms stretching? Is inventory building faster than sales? A new issue can raise money and still be exposed if the cash is consumed by growth. In 2026, with financing costs still relevant for many UK firms, a thin working capital position deserves a discount, not a premium.

7. Who guards the till?

Governance is not a box-ticking exercise. Look at the board: independent directors, the chair, the audit committee and the senior management team. Check whether the company has a controlling shareholder and how related-party transactions are handled. Read the section on risk factors, but do not treat length as a substitute for clarity. A prospectus that is candid about weaknesses is more trustworthy than one that reads like a brochure. The best new issues tend to have boards that can say no to the founder.

A repeatable discipline

Before buying any new UK listing in 2026, write down your answers to these seven questions. If you cannot answer them from the prospectus, wait. The market will offer other opportunities. A listing is not a favour to the company, and a first-day pop is not evidence of quality. The prospectus is there to be used. Read the cash flow, test the claims and decide whether the business deserves your capital at the price being asked.
