🕒 1. Speed — shells are almost always faster
Step Buying a shell New IPO (LSE/AIM)
Legal vehicle Already exists and listed Must incorporate and then apply for listing
Regulatory review Treated as a Reverse Takeover (RTO) — LSE/AIM must vet the deal and issue a new admission document Full IPO process, including prospectus and FCA review
Time frame (realistic) 2–4 months (if clean shell, simple acquisition) 6–12 months for a full IPO (prospectus, accountants’ report, due diligence, marketing)
So yes, buying and repurposing a listed shell can be roughly twice as fast — if it’s clean and the RTO proposal is straightforward.
But: if the shell has legacy issues (e.g., liabilities, shareholder disputes, delisting risk), it can quickly take longer than a fresh IPO.
💷 2. Cost comparison
Cost component Shell purchase (RTO) New IPO
Listing/Admission RTO admission document (cheaper than a full prospectus if AIM; full prospectus if Main Market) Full prospectus, FCA fees, listing fees
Legal & DD fees £150 k–£400 k typical (AIM), can exceed £1 m on Main Market if complex £500 k–£2 m+ typical for full IPO process
Broker/Nomad Must appoint a Nomad (AIM) or Sponsor (Main Market) anyway Same
Shell acquisition cost Usually £500 k–£2 m, depending on the shell’s cash and value of listing £0 (you create your own company, but pay for IPO process)
🔸 Overall:
A clean AIM shell RTO may total £0.7 – 2 m and finish in 2–4 months.
A new AIM IPO often costs £1.5 – 3 m+ and takes 6–12 months.
On the Main Market (Standard or Premium), costs and timelines roughly double those figures.
⚖️ 3. Regulatory difference
A reverse takeover (buying a shell and injecting a business) effectively re-lists the shell as a new entity.
Requires shareholder approval.
The company’s shares are suspended during the process.
After completion, it’s re-admitted with new name, ticker, and usually new board.
A new listing involves an FCA-approved prospectus (for Main Market) or admission document (for AIM).
Longer due diligence, more marketing, more investor relations setup.
