Unquoted shares are ownership stakes in companies that don’t trade on a public stock exchange like the NYSE or Nasdaq. Because there’s no ticker updating a price every second, the shares are valued through professional appraisal, sold under contractual restrictions, and generally available only to investors who meet specific financial thresholds. A formal appraisal can run from a few thousand dollars for an early-stage startup to $50,000 or more for a complex enterprise, and the resulting number matters for stock option pricing, estate filings, employee tax bills, and any eventual sale.
How Unquoted Shares Differ From Public Stock
The biggest practical difference is liquidity. Publicly traded shares sell in seconds during market hours at a price everyone can see. Selling unquoted shares means finding a buyer yourself, negotiating a price without a public benchmark, and clearing contractual restrictions that may limit who you can sell to. The process can take months.
Information availability is the second gap. Public companies file quarterly and annual reports with the SEC, giving any investor access to standardized financial data. Private companies face far lighter disclosure rules. You’ll usually see financial statements only if you’re already a shareholder, and those statements may not follow the same auditing standards. If you’re considering buying in, the burden falls on you to investigate the company’s finances before committing money.
The regulatory framework is also different. Public offerings must be registered with the SEC under the Securities Act of 1933, which imposes detailed disclosure and anti-fraud requirements.1Legal Information Institute. Securities Act of 1933 Private companies sidestep full registration by relying on exemptions, most commonly Regulation D, which allows them to raise unlimited capital without going through the public offering process.2U.S. Securities and Exchange Commission. Exempt Offerings The tradeoff is that these exemptions restrict who can invest and how shares can later be resold.
Who Can Buy Unquoted Shares
Most private placements under Rule 506 of Regulation D are limited to accredited investors.3U.S. Securities and Exchange Commission. Private Placements – Rule 506(b) The SEC sets specific financial thresholds you must meet to qualify:
- Income of more than $200,000 individually (or $300,000 jointly with a spouse or partner) in each of the prior two years, with a reasonable expectation of the same in the current year.
- Net worth exceeding $1 million, excluding the value of your primary residence, either individually or jointly.
- Certain securities licenses (Series 7, Series 65, or Series 82) held in good standing, which qualify you regardless of income or net worth.
These thresholds exist because unquoted shares carry risks that public market investors don’t face: limited information, no guaranteed exit, and the possibility that the company never reaches a liquidity event.4U.S. Securities and Exchange Commission. Accredited Investors Under Rule 506(b), a company can also sell to up to 35 non-accredited investors, but must provide them with more extensive disclosure documents.
How Unquoted Shares Are Valued
Without a stock exchange setting the price, someone has to figure out what the shares are worth. Qualified independent appraisers do this work, drawing on three recognized approaches and then weighing the results based on which method best fits the company.
The Market Approach
The market approach asks what similar companies have recently sold for. The appraiser identifies comparable private transactions or publicly traded companies in the same industry, then applies their valuation multiples to the subject company. When using public company comparables, the appraiser adjusts downward because a private company’s shares can’t be sold as easily. That adjustment, called the Discount for Lack of Marketability, typically runs 30% to 50% of what the shares would theoretically be worth on an exchange. Investors pay less for an asset they can’t quickly convert to cash.
The Income Approach
The income approach, usually run as a discounted cash flow analysis, projects the company’s expected future cash flows over a defined period and calculates what those future dollars are worth today. The discount rate is often the company’s weighted average cost of capital, which accounts for the risk of putting money into the business. Higher risk, lower present value.
This is where most valuation disputes happen. The model’s output is only as good as its assumptions about revenue growth, profit margins, and terminal value. Small changes in the growth rate or discount rate can swing the final number dramatically.
The Asset Approach
The asset approach calculates value by adding up the fair market value of everything the company owns, tangible and intangible, then subtracting all liabilities. It fits best when value lies in hard assets rather than earnings potential, and it’s the standard approach for a company winding down, because it answers what shareholders would receive if everything were sold and all debts paid.
Common Versus Preferred
Not all private shares are worth the same. Venture-backed companies typically issue preferred shares to investors and common shares to founders and employees. Preferred shares carry liquidation preferences, meaning those holders get paid first, often at a guaranteed multiple of their investment, before common shareholders see anything in a sale or liquidation. A 1x liquidation preference is standard, though 2x or 3x preferences appear in tougher fundraising environments. Common shares are worth less than preferred shares in the same company, and any credible valuation accounts for that gap.
409A Valuations and Employee Stock Options
Any private company that grants stock options to employees must set the exercise price at or above the stock’s fair market value on the grant date. Section 409A of the Internal Revenue Code governs this requirement, and the penalties for underpricing fall on the employee: a 20% additional tax on top of regular income tax, plus interest calculated from the year the options were granted.5Office of the Law Revision Counsel. 26 USC 409A – Inclusion in Gross Income of Deferred Compensation The employee bears the tax hit even though the company set the price.
To avoid that outcome, private companies obtain a 409A valuation from an independent appraiser. A qualified third-party appraisal creates a safe harbor presumption that the IRS can only challenge by showing the valuation was grossly unreasonable.6eCFR. 26 CFR 1.409A-1 – Definitions and Covered Plans The appraisal must be no more than 12 months old at the time options are granted, and any material event in between (a new funding round, a major acquisition, a dramatic shift in revenue) requires an immediate update regardless of timing.
Buying and Selling Unquoted Shares
Selling unquoted shares isn’t as simple as placing a market order. Shareholder agreements almost always impose procedural hurdles that must be cleared before any transfer.
Transfer Restrictions
The most common restriction is the right of first refusal. Before you sell to an outside buyer, you must offer your shares to the company or existing shareholders at the same price and on the same terms the outside buyer agreed to.7U.S. Securities and Exchange Commission. Right of First Refusal and Co-Sale Agreement – Provention Bio, Inc. Only after they decline can you proceed with the third-party sale.
Two other provisions show up regularly. Tag-along rights let minority shareholders sell on the same terms when a majority holder sells, so they aren’t left behind in a deal they didn’t choose. Drag-along rights work in the opposite direction, allowing a majority shareholder to force minority holders into a sale. Both prevent situations where a partial buyout leaves some shareholders trapped or a buyer walks away because they can’t acquire full ownership.
The Share Purchase Agreement
Once transfer restrictions are waived or satisfied, the sale is documented in a share purchase agreement. That contract specifies the price, the representations each party makes about the shares and the company, and any conditions that must be met before closing. After execution, the company updates its capitalization table to record the new ownership structure.
Rule 144 Holding Periods
Federal securities law adds its own timeline on top of contractual restrictions. Under SEC Rule 144, if the issuing company files regular reports with the SEC, you must hold restricted shares for at least six months before reselling them. If the company doesn’t file those reports, which is the case for most private companies, the holding period extends to one year.8eCFR. 17 CFR 230.144 – Persons Deemed Not to Be Engaged in a Distribution The clock doesn’t start until you’ve fully paid for the shares.9U.S. Securities and Exchange Commission. Rule 144 – Selling Restricted and Control Securities
Tax Rules That Apply Only to Private-Company Stock
Several tax provisions apply to unquoted shares and not to public stock. Used correctly, they can significantly reduce your tax bill. Missed or mishandled, they can cost you far more than you’d expect.
Qualified Small Business Stock (Section 1202)
If you hold shares in a qualifying C corporation with gross assets under the statutory threshold, Section 1202 of the Internal Revenue Code allows you to exclude a portion of your capital gains from federal tax when you sell.10Office of the Law Revision Counsel. 26 USC 1202 – Partial Exclusion for Gain from Certain Small Business Stock The rules changed in mid-2025 under the One Big Beautiful Bill Act, so the date your stock was issued matters.
For shares issued before July 5, 2025, holding for more than five years qualifies you for up to a 100% exclusion, capped at the greater of $10 million or ten times your adjusted basis in the stock. For shares issued after July 4, 2025, the exclusion phases in: 50% after three years, 75% after four, and 100% after five. The per-issuer cap for post-OBBBA stock rises to $15 million (indexed for inflation starting in 2027), and the company’s gross asset ceiling rises from $50 million to $75 million. Any unexcluded gain on shares held for only three or four years is taxed at 28% rather than the usual long-term capital gains rates.
The qualification rules are strict. The company must be a domestic C corporation, you must have acquired the stock at original issuance rather than on a secondary market, and the company must use at least 80% of its assets in an active trade or business. Finance, hospitality, and professional services industries are excluded.
Section 1244: Ordinary-Loss Treatment When It Doesn’t Work Out
Not every investment works out, and Section 1244 provides a cushion. If your shares qualify, you can treat losses on the sale as ordinary losses rather than capital losses. The difference is substantial. Ordinary losses offset regular income dollar for dollar, while capital losses are capped at $3,000 per year against ordinary income, with the rest carried forward. The annual limit on ordinary loss treatment is $50,000 for individual filers or $100,000 on a joint return. To qualify, the corporation must have received no more than $1 million in total capital contributions when the stock was issued.11Office of the Law Revision Counsel. 26 USC 1244 – Losses on Small Business Stock
The Section 83(b) Election
Founders and early employees often receive restricted stock that vests over time, typically on a four-year schedule. Without any election, you owe ordinary income tax on the shares as they vest, based on fair market value at each vesting date. If the company’s value climbs, so does the tax bill at every milestone.12Office of the Law Revision Counsel. 26 USC 83 – Property Transferred in Connection with Performance of Services
Filing a Section 83(b) election flips that. You pay ordinary income tax immediately on the value of the shares at grant, which for a brand-new startup is often close to zero. All future appreciation is then taxed at capital gains rates when you sell, rather than as ordinary income at each vesting date. The catch: you must file the election within 30 days of receiving the shares, with no extension and no do-over.13Internal Revenue Service. Instructions for Form 15620, Section 83(b) Election Miss that 30-day window and you’re locked into the default tax treatment for that grant.
The risk runs both ways. If you file the election and later forfeit the shares (because you leave the company before vesting, for example), you don’t get a refund on the tax you already paid. The election is a bet that the shares will be worth more later, and that you’ll stick around long enough to keep them.
