What does it cost to take a holding company public and keep it public?

What are the one-time costs of listing?

These are paid once, before or at listing. The categories are similar across routes. The size of each depends on the route and on how ready the company is.

• Securities counsel. Drafting the registration statement or merger documents, and answering SEC comments.
• Audit. PCAOB-audited financials for the parent. A holding company that has made acquisitions may also need audited financials for businesses it bought, depending on their size.
• Accounting clean-up. Consolidating subsidiaries, closing the books on a schedule and fixing records an auditor will not accept.
• Reorganization. Moving operating companies under the listing parent, with legal and tax work and lender consents.
• Market and agent fees. OTC Markets charges an application fee and an annual fee; check its current fee schedule. A transfer agent maintains the share register.
• Route-specific costs. Underwriting in an IPO. Acquiring a shell and its diligence in a reverse merger. Market-maker and registration work in a direct listing.

For figures by route, see PublicFinancial on direct listing costs and reverse merger costs.

What does it cost to stay public?

These costs recur every year for as long as the company is listed. They are the ones that decide whether listing pays.

• SEC reporting. Quarterly and annual reports, plus current reports when material events occur.
• Annual audit and quarterly reviews. By a PCAOB-registered firm.
• Certifications and controls. As of October 2026, the OTCQB requires an annual CEO and CFO certification. Larger markets add more.
• Market fees. OTC Markets or exchange annual fees.
• Legal. Ongoing securities counsel for filings, insider trading policies and share issuances.
• Investor relations. Communicating with shareholders and the market.
• Insurance. Directors' and officers' cover.
• Finance staff. A CFO and controller able to close every subsidiary's books in time for the reporting calendar.

For current figures, see PublicFinancial on the ongoing costs of being public.

What costs do not show up on an invoice?

• Dilution. Shares issued to pay advisers, raise capital or pay sellers spread ownership. Castellum, on NYSE American, saw its share count rise from about 53M to about 94.6M between March 2024 and March 2026.
• Management time. Quarterly reporting, audits and investor calls take hours that would otherwise go to operations and deals.
• Disclosure. Competitors, employees and sellers can read your results.
• Market risk. A falling share price makes stock a more expensive currency. A study of 6,000+ IPO registrations found stock-paid deals underperform cash deals by 20–30 percentage points over 3–5 years.

Adviser fees often include equity as well as cash. Our Go Public engagement, for example, is a monthly retainer plus equity, set in a proposal, with third-party costs separate. Count any equity paid to advisers as a cost.

Worked example: what recurring costs do to value

Recurring costs are paid out of earnings, and earnings are valued at a multiple. So every recurring dollar costs more than a dollar of value. The $100,000 below is a unit for the arithmetic, not an estimate of your costs.

1. At the site's illustrative 10x platform multiple: $100,000 of annual cost x 10 = $1M less value.
2. At GF Data's 2024 median of 6.5x for $10–100M companies: $100,000 x 6.5 = $650,000 less value.
3. At 4.5x, the median for $1–10M companies: $100,000 x 4.5 = $450,000 less value.

Now the other side. On the site's illustrative math, $1M of profit bought at 4x ($4M) supports $10M of value inside a platform valued at 10x. If being public is what makes that 10x possible, through stock as currency and access to capital, the recurring cost can be worth paying. If the market values you at a low multiple, it rarely is.

Run this test with your real cost quotes and a low, middle and high trading multiple before you decide.

If you are deciding now

• Get audit-readiness right first. Unready books raise every cost on the list.
• Price the recurring costs before the one-time costs. They decide whether listing pays.
• Treat dilution as a cost and budget it.
• Compare the total with what you would pay to raise private capital and fund deals with debt and seller notes.

On timing, this site's working estimate is roughly 6 months by reverse merger or IPO and about 10 months by direct listing. See PublicFinancial on timing.

Where these numbers come from: OTCQB certification and fee guidance are from the OTCQB Rules, version 6.1. Multiples by deal size are GF Data 2024 medians reported by Carry and Conquer. Castellum figures are from this case review. Stock-paid deal performance is from the study reported on the CLS Blue Sky Blog. Cost figures by route are at PublicFinancial. The 10x multiple and the $100,000 unit are illustrative.

Which route is cheapest?

It depends on the company and the route's specific costs, so compare current figures at PublicFinancial. The recurring costs are similar whichever route you take, which is why they matter more.

Can I cut costs by listing on the OTC instead of Nasdaq?

The OTCQB has lower entry standards than Nasdaq. You still need PCAOB-audited financials, current SEC reporting and an annual CEO and CFO certification, so the core costs remain.

Should equity paid to advisers count as a cost?

Yes. Shares paid to advisers dilute every other holder. Value them at the price you expect after listing and add them to the cash costs.
