Get StartedIPO Services to Take Your Business Public Successfully
Conducting a business IPO is a transformative experience that can provide access to powerful levels of growth-fueling capital. The trade-off is increased public and regulatory scrutiny that can require reshaping how your business operates.
In some industries, options to go public are available but require focused guidance from an experienced team of CPAs. The most popular path is an RTO on the CSE or TSX exchange in Canada. GreenGrowth CPAs has the experience and industry expertise to guide you through every step of the process. For companies that have already listed, see our public company audit services.

IPO Services FAQs
What audit is required for a US IPO?
Companies preparing for a US IPO under SEC registration require a PCAOB-registered auditor to perform audits of their financial statements. This is different from a standard GAAS audit, since PCAOB standards involve stricter independence, quality control, and documentation requirements. GreenGrowth CPAs is PCAOB registered and experienced with SEC registration requirements.
What is an RTO and how does it differ from a traditional IPO?
An RTO (Reverse Takeover) is an alternative path to going public, typically on the CSE or TSX in Canada, where a private company merges with an existing public shell company. RTOs can be faster and less expensive than a traditional IPO, but still require audited financial statements, regulatory compliance, and financial disclosure. GreenGrowth CPAs has experience with both paths.
What is SOX compliance and why does it matter for an IPO?
Sarbanes-Oxley (SOX) requires public companies to maintain and document internal controls over financial reporting. Implementing SOX controls before going public, rather than after, significantly reduces the risk of material weaknesses and deficiencies being identified post-listing. GreenGrowth CPAs helps companies build SOX-ready control frameworks as part of the pre-IPO process.
How early should we engage GreenGrowth CPAs before an IPO?
Ideally 12 to 18 months before a planned listing. Early engagement allows time for financial statement restatements if needed, SOX readiness implementation, SEC registration support, and the audit of the required historical periods. Companies that engage too late often face delays and additional costs during the process.
What is the difference between an S-1 and an F-1 registration statement?
An S-1 is the SEC registration statement used by US-based companies going public on a US exchange. An F-1 is the equivalent registration statement used by foreign private issuers listing in the US. Both require audited financial statements (typically three years), MD&A, risk factors, and detailed financial disclosures. The choice depends on the issuer's jurisdiction and reporting obligations.
How does going public on the CSE differ from listing on the TSX or NYSE?
The Canadian Securities Exchange (CSE), Toronto Stock Exchange (TSX), and US exchanges like NYSE and Nasdaq each have different listing standards, minimum financial requirements, and ongoing compliance obligations. CSE has lower listing thresholds and is popular for cannabis and earlier-stage companies. TSX has higher requirements suited to more established issuers. US exchanges require the most rigorous reporting, including PCAOB audits and SEC compliance. GreenGrowth CPAs supports listings on each.
