The accounting requirements for over-the-counter (OTC) companies turn on which OTC Markets tier the company trades on. OTCQX and OTCQB companies prepare audited financial statements under U.S. GAAP (or IFRS for international issuers), file annual and quarterly reports on fixed deadlines, and disclose material events within four business days. Pink Market companies operate under a much lighter framework where audits are optional and disclosure ranges from quarterly reporting to nothing at all.
The Three Tiers and What Each One Demands
OTC Markets Group runs three marketplaces, and the tier a company sits on dictates the accounting workload.
OTCQX Best Market
OTCQX is the top tier. U.S. issuers must follow U.S. GAAP, produce audited annual financial statements, and maintain ongoing disclosure comparable to a NYSE or NASDAQ listing.1OTC Markets Group. OTCQX Rules for U.S. Companies The audit must come from a PCAOB-registered firm and produce an opinion that is not adverse, disclaimed, or qualified. Many OTCQX companies are also SEC-reporting issuers and file 10-Ks and 10-Qs through EDGAR alongside the OTC Markets rules.
OTCQB Venture Market
OTCQB is aimed at earlier-stage companies. It also requires audited annual financials under U.S. GAAP (or IFRS for international companies), and U.S. issuers must use a PCAOB-registered auditor.2OTC Markets Group. OTCQB Rules Interim reports can be unaudited, but they must include a balance sheet, income statement, and statement of cash flows covering the current period and the comparable prior-year period. Companies must also complete an annual verification and management certification to keep their listing.3OTC Markets. OTCQB Venture Market
Pink Market
Pink is where the accounting requirements loosen. Companies fall into three disclosure categories: Current Information, Limited Information, and No Information. A Current Information company must publish quarterly reports within 45 days of quarter end and an annual report within 90 days of fiscal year end.4OTC Markets Group. Disclosure Guidelines for the Pink Market Those financial statements do not need a full PCAOB audit. Reviewed or even unaudited financials can satisfy the requirement, but a company that skips the PCAOB audit must submit an attorney letter from a qualified securities attorney verifying its disclosures, filed within 120 days of fiscal year end.5OTC Markets Group. OTC Pink Basic Disclosure Guidelines
Limited Information companies publish minimal disclosure, often because they are in financial distress or bankruptcy. No Information companies publish nothing, which means any accounting data available on them cannot be relied on.
How Financial Statements Must Be Prepared
U.S. issuers on OTCQX and OTCQB prepare their financials under U.S. GAAP. A complete set includes a balance sheet, an income statement, a statement of cash flows, and footnote disclosures covering revenue recognition policies, asset valuation methods, and material risks. International issuers can use IFRS or an IFRS equivalent, depending on what their home country regulator requires.2OTC Markets Group. OTCQB Rules
Pink Market companies reporting under the Alternative Reporting Standard follow more flexible guidelines. Their annual and quarterly reports must still contain basic financial statements, but the depth of disclosure falls well short of a full GAAP set.
One requirement catches companies off guard. All OTCQX and OTCQB companies must maintain a verified company profile through OTCIQ, and their transfer agents participate in the Transfer Agent Verified Shares Program, which requires daily submission of updated share data.6OTC Markets. Transfer Agent Verified Shares Program Accurate share counts flow directly into the financial statements through earnings-per-share calculations and dilution disclosures.
Audit Standards and Opinion Types
Audit assurance is where the tiers diverge most sharply.
OTCQX companies must have their annual financials audited by a PCAOB-registered firm, and the opinion must be clean.1OTC Markets Group. OTCQX Rules for U.S. Companies PCAOB registration means the auditor is subject to Board inspections and quality-control standards, which is the highest level of assurance available in the OTC space.7Public Company Accounting Oversight Board. About PCAOB Registration
OTCQB rules match for U.S. issuers: audited annual financials, PCAOB-registered auditor, clean opinion. International companies on OTCQB are exempt from the PCAOB requirement. Regulation A Tier 2 companies are also exempt at initial eligibility, but only for the first year — after that, they need a PCAOB audit like everyone else.2OTC Markets Group. OTCQB Rules
Pink Market companies get the lightest treatment. Reviewed or unaudited statements can qualify a company for Current Information status, provided the attorney letter substitutes for the missing PCAOB audit. The attorney letter is not a formality. It requires counsel to review the disclosures and confirm they contain no material misstatements.
Audit opinions themselves come in grades. An unqualified opinion says the financials are fairly presented under the applicable framework. A qualified opinion flags a specific, isolated issue while accepting the rest. An adverse opinion says the statements are not fairly presented, which typically triggers removal from the tier. A disclaimer of opinion means the auditor could not gather enough evidence to reach any conclusion.
Filing Deadlines and Management Certifications
Getting listed is one thing. Staying listed means filing on a fixed schedule.
OTCQX and OTCQB companies file annual reports within 90 days of fiscal year end and quarterly reports within 45 days of each quarter end.8OTC Markets Group. Ongoing Disclosure Obligations SEC-reporting companies satisfy the deadlines by keeping their EDGAR filings current. Non-SEC reporters file through OTCIQ, which feeds the OTC Disclosure & News Service.
Pink Current Information companies follow the same 90-day annual and 45-day quarterly cadence.4OTC Markets Group. Disclosure Guidelines for the Pink Market Miss a deadline and the company can lose its Current Information status, dropping to Limited Information or worse.
OTCQX and OTCQB companies carry an additional annual obligation: the CEO and CFO must sign a certification attesting to the accuracy of the company’s public disclosures and confirming compliance with the tier’s rules.9OTC Markets Group. OTCQB Application Guide for U.S. Companies This is a personal certification, not a compliance-department form letter.
Material Event Reporting
Beyond periodic filings, OTCQX and OTCQB companies must publicly disclose material events within four business days of occurrence, using a press release posted through OTCIQ.10OTC Markets Group. OTCQX U.S. and OTCQB Disclosure Guidelines A material event is anything a reasonable investor would weigh in a buy-or-sell decision.
OTC Markets identifies 15 specific triggering events. They fall into a few categories:
- Entering into or terminating a material contract, or completing an acquisition or sale of major assets.
- Creating a significant new debt obligation or triggering acceleration of existing debt.
- Changing auditors, discovering that previously issued financial statements can’t be relied on, or recording a material impairment.
- Changes in control, departure or appointment of directors and officers, or amendments to articles of incorporation or bylaws.
- Material modifications to shareholder rights, or sales of equity securities.
Sitting on material information beyond the four-day window can trigger compliance action from OTC Markets Group, up to a tier downgrade. Someone inside the company needs to own the job of spotting disclosable events in real time and getting them published.
Foreign Issuer Requirements
Foreign companies can trade on U.S. OTC markets without fully reconciling to U.S. GAAP, but they still have meaningful obligations. An international company on OTCQX must publish, in English through the OTC Disclosure & News Service, the annual reports, interim reports, and material disclosures that its home country regulator requires or that are called for by SEC Rule 12g3-2(b).11OTC Markets Group. OTCQX Rules for International Companies
The Rule 12g3-2(b) exemption under the Securities Exchange Act is the mechanism that lets a foreign private issuer avoid full SEC registration, provided it maintains a listing on one or more exchanges in its primary trading jurisdiction and is not otherwise required to file under Section 13(a) or 15(d).12eCFR. 17 CFR 240.12g3-2
If a foreign company on a Qualified Foreign Exchange misses a required home-country filing deadline, it must post a late filing notification through the OTC Disclosure & News Service within one business day.11OTC Markets Group. OTCQX Rules for International Companies International companies on OTCQB skip the PCAOB requirement but still need audited financials under IFRS or an equivalent standard.2OTC Markets Group. OTCQB Rules
What Happens When Reporting Lapses
The consequences of falling out of compliance reach past a status label. Companies that stop making current information publicly available can be moved to the Expert Market, where broker-dealers can only publish unsolicited quotes. The Expert Market does not restrict who can execute a trade, but it sharply limits price transparency and discoverability, and most retail investors will never see these stocks.13OTC Markets Group. Understanding the Expert Market
Part of the driver is SEC Rule 15c2-11, which requires broker-dealers to review current company information before publishing quotations for OTC securities.14U.S. Securities and Exchange Commission. SEC Proposes Amendments to Exchange Act Rule 15c2-11 Stop providing that information and broker-dealers cannot initiate quotes. The stock effectively becomes illiquid.
Separately, OTC Markets Group applies a Caveat Emptor designation, marked with a skull-and-crossbones symbol, when there is a public interest concern about a company. Triggers include spam campaigns, questionable stock promotions, known investigations of fraudulent activity involving the company or its insiders, regulatory suspensions, and disruptive corporate actions.15OTC Markets Group. Compliance Flags The flag can be applied to a company on any tier and signals that available accounting information may be unreliable.
Getting back into good standing is straightforward but slow: catch up on required filings, produce the attorney letter or PCAOB audit for the target tier, and reapply. The longer a company sits at a lower tier or on the Expert Market, the harder it becomes to attract market makers willing to quote the stock.
