Red Flags & Price Levers

Customer concentration

"How has the mix of top-10 customers changed over the last three years?"

Property lease expiring 2027

"It would be helpful to understand the landlord relationship and renewal terms."

Key person dependency on owner

"How would the business run through a six-month transition?"

Price levers
  • • Working capital normalisation — the current model likely holds excess cash.
  • • Property lease renewal ahead of completion may unlock a rent reset.
  • • Owner add-backs — personal expenses and above-market director pay.

Michael Granton
Granton Storage Solutions Ltd

Dear Michael,

I hope this note finds you well. I'm writing personally rather than through an adviser because I wanted the first contact to come from me directly.

I've followed Granton Storage Solutions Ltd for some time. What has stood out — and what has prompted me to write — is the way the Aylesbury site has held its occupancy through the last two years while a nearby operator was consolidated in January. In a sub-segment where scale is often confused with quality, a business run with that kind of care is unusual and, in my view, undervalued by the trade press.

I'm not a broker. I represent a small group of committed investors who back founder-led businesses like yours through the transition that inevitably comes with 29-plus years of building something. We are not a consolidator. We are not looking to strip out costs, rebrand the sites, or move the head office. We are looking to be the right custodian for one more chapter.

I would welcome a private conversation, on your terms, at a location of your choosing. There is no expectation of a transaction from the meeting. If, after we have met, you decide it is not the right moment or the right partner, I will not press the matter, and I will not reappear through a third party.

If it would be easier, I am happy to meet with your accountant present. I would rather begin the relationship the right way than the fast way.

With warm regards,

Alex Chen

P.S. — I have enclosed a short note on how we handled the first hundred days at two comparable businesses. It is not a pitch. It is simply the shape of what we do.
