Which small holding companies have gone public, and what happened?

What happened in our best outcome?

This is our best outcome, not a typical one. A company went public with about $1.5M in revenue at a $3.5M starting valuation, after raising about $100,000. Over seven years, the founder:

• Made three acquisitions. One failed and was closed. One succeeded.
• Sold the original business.
• Moved the company to Nasdaq.
• Sold the company for $240M in cash.

What it shows:

• A company can list small. Revenue at listing was about $1.5M.
• Acquisitions did not all work. One of the three failed and was closed.
• The company changed shape. The founder sold the original business along the way.
• It took seven years. The listing was the start of the work.

What did Tiny do?

Tiny is a well-known small holding company that chose to list. It did so on the TSX Venture Exchange through a reverse takeover, in which a private company becomes public by combining with an existing listed company.

The lesson is about route and venue. A holding company does not have to use an IPO or list on a major exchange to become public. Reverse mergers and junior markets are real options with their own costs and risks. For what a reverse merger involves and costs, see PublicFinancial on reverse merger costs.

What does Castellum show?

Castellum is listed on NYSE American. It paid more than 80% of a roughly $6.6M acquisition in restricted stock. Between March 2024 and March 2026, its share count rose from about 53M to about 94.6M.

The arithmetic of that dilution:

1. Stock portion of the acquisition: more than 80% x $6.6M = more than about $5.3M paid in shares.
2. Share count growth: 94.6M / 53M = about 1.78 times as many shares in two years.
3. Effect on an existing holder: someone who owned 1% in March 2024 and bought no more would own about 53 / 94.6 = 0.56% in March 2026.

The lesson is issuance discipline. Each new share has to bring in more earnings than it spreads away. If not, owners lose ground even as the company grows.

What does Teamshares show?

Teamshares buys businesses with roughly $0.5 million to $5 million of EBITDA from retiring owners and helps employees earn company stock. It went public by merging with Live Oak Acquisition Corp. V, a special purpose acquisition company (SPAC). Its Form 8-K gives June 18, 2026 as the closing date. The closing press release followed on June 19. The deal came with a PIPE of 13,750,000 shares for about $126.5 million of gross proceeds. The stock has traded on Nasdaq as TMS since June 23, 2026.

The lesson is that a public company can be built on buying businesses in the size range many private buyers target. The route was institutional: a SPAC sponsor, a shareholder vote and PIPE investors. That route is rarely open to a holding company with two or three businesses. See what Teamshares' listing means for small-business holding companies.

What happened to MBH?

MBH Corporation plc was a UK "agglomeration" holding company of about 19 companies. It was listed on the Aquis Stock Exchange (AQSE). It delisted in January 2024 and entered administration in February 2024.

This article does not speculate on every cause. The lesson that holds without speculation is simple. Being listed did not keep a holding company of many small businesses solvent. A listing gives access to capital and a share price. It does not supply earnings, integration or cash.

What patterns do the examples share?

Read together with the academic evidence, five patterns stand out:

1. Listing is a tool, not a result. The $240M outcome took seven years of acquisitions, a failed deal and a sale of the original business.
2. Stock is a currency that can be overspent. A study of 6,000+ IPO registrations from 1990 to 2024 found that, among newly public firms, stock-paid deals underperform cash deals by 20–30 percentage points over 3–5 years and are about 50% more likely to end in delisting. Castellum's share count shows how fast issuance adds up.
3. Route and venue are choices. Tiny used a reverse takeover on a junior exchange. Teamshares used a SPAC merger and a PIPE. Our best outcome later moved to Nasdaq.
4. Some acquisitions fail. Plan for it. Close what does not work rather than fund it.
5. Many small businesses are not a platform by themselves. MBH held about 19 companies and still failed.

How should you judge a public holding company?

If you are studying listed holding companies as models, or considering taking stock from one as a seller, check:

• Share count over the last two to three years, and how much of the increase came from acquisitions.
• How acquisitions were paid: cash, debt, seller notes or stock, and in what proportions.
• Audited earnings, not adjusted figures alone.
• Whether the businesses it owns are integrated or simply collected.
• The trading venue, trading volume and any history of delisting notices.

My view is that going public fits only holding companies with real earnings or a clear path to them, books an auditor can work with and an acquisition program. These examples show both sides of that view.

Where these numbers come from: Castellum figures are from this case review. Teamshares' closing date, PIPE and ticker are from the Teamshares Form 8-K, and its business description and press release date are from the Teamshares closing press release. MBH delisting and administration dates are from TheBusinessDesk. Stock-paid deal performance is from the study reported on the CLS Blue Sky Blog. The $1.5M, $3.5M, $100,000 and $240M figures are from a Meraki Partners client and are our best outcome, not a typical one.

Related questions

Are there many small public holding companies?

Some exist, on junior markets and on larger exchanges. They vary widely in quality. Judge each on audited earnings, share issuance and how it pays for deals.

Was the $240M outcome typical?

No. It is our best outcome, not a typical one. Results vary widely, and some listed holding companies fail, as MBH did.

What would have protected MBH's shareholders?

The sources cited here do not set out every cause, so any answer would be guesswork. The general protections are audited earnings, integration of acquired businesses and restraint in issuing shares.
