What is a SPAC?

Special purpose acquisition companies (SPACs) raise capital through an initial public offering (IPO) for the purpose of merging with or acquiring an operating company, referred to as the “target”. For the target company, merging with or being acquired by a SPAC is an alternative path that management teams can take to access the public markets and achieve liquidity for its shareholders in lieu of executing its own traditional IPO.

The SPAC merger pathway offers several distinct advantages over a traditional IPO. These advantages include providing valuation certainty and expected ownership dilution at the onset of the “going public” journey. By comparison, the traditional IPO pathway subjects companies to market volatility and pricing uncertainty until the road-show and book-building process at the end. The SPAC merger approach also provides management teams the ability to negotiate more customized deal terms, such as minimum cash requirements as closing conditions or deal structures that link valuation and ownership dilution to post close, or post de-SPAC, performance—features that are not available in a standard IPO.

There are several challenges experienced in a SPAC merger, notably having to potentially meet an accelerated public company reporting timeline as well as navigating different legal and financial reporting requirements. The target company’s management team will need to focus on being ready to operate as a public company within three to five months of signing a letter of intent.

SPAC formation and funding

A SPAC is generally formed by an experienced management team or a sponsor with nominal invested capital, though the shares held by the sponsor typically equate to a ~20% stake in the SPAC’s capitalization, known as the “founder shares”, “sponsor shares”, or the “promote”. The remaining ~80% stake is held by public shareholders through “units” offered in the SPAC’s IPO. Traditionally, each publicly traded unit consists of a share of common stock and a fractional warrant (e.g., ½ or ⅓ of a warrant). More recently, the IPO units offered in SPAC IPOs no longer include warrants. But the units do include automatic rights to receive additional shares of common stock (e.g., ⅒ of a share) upon closing of the deal with a target company, known as the “de-SPAC”. Sponsors typically also purchase warrants or share rights.

Founder shares and public shares generally have similar voting rights, with the exception that founder shares usually have sole right to elect the SPAC directors prior to the de-SPAC. Warrant and share right holders generally do not have voting rights, and only whole warrants are exercisable and only whole share rights are settled in shares.

Typical SPAC timeline

SPAC life cycle
SPAC life cycle

A SPAC’s IPO is typically based on an investment thesis focused on a sector and geography, such as the intent to acquire a technology company in North America, or a sponsor’s experience and background. Following the IPO, proceeds are placed into a trust account and the SPAC typically has 18-24 months to identify and complete a merger with a target company. If the SPAC does not complete a merger within that time frame, the SPAC may seek shareholder approval to extend the life of the SPAC or will be required to liquidate and return the IPO proceeds held in the trust account to the public shareholders.

Once a target company is identified and a merger is announced, the SPAC’s public shareholders will vote for or against the transaction and separately decide whether to redeem their shares or not. If the SPAC requires additional funds to complete a merger, the SPAC may issue debt or issue additional shares, such as a private investment in public equity (PIPE), as a backstop. The backstop financing is typically contemplated upfront in connection with the merger negotiations between the SPAC and the target’s management teams to ensure that a minimum amount of cash remains available post redemptions of the SPAC’s public shareholders, along with a base of committed investors who believe in the equity story of the target.

The SPAC merger

The SPAC will typically need to solicit shareholder approval for a merger and will prepare and file a proxy statement (or a joint registration and proxy statement on Form S-4 if it intends to register new securities as part of the merger). This document will contain various matters seeking shareholder approval, including a description of the proposed merger and governance matters. It will also include financial and non-financial disclosures of the target company, such as historical financial statements, management’s discussion and analysis (MD&A), pro forma financial information showing the effect of the merger, risk factors, and a description of the target’s business.

Once shareholders approve the SPAC merger and all regulatory matters have been cleared, the merger closes and the target company becomes a public entity. A Form 8-K, with information equivalent to what would be required in a Form 10 filing of the target company (commonly referred to as the Super 8-K), must be filed with the US Securities and Exchange Commission (SEC) within four business days of closing.

Regulatory updates

In recent years the SEC issued updated guidance for SPACs and de-SPAC transactions designed to enhance transparency and investor protection. The rules:

  • Require new disclosures about the identity and compensation of SPAC sponsors, potential conflicts of interest, and shareholder dilution;
  • Deem the de-SPAC transaction to be a sale of securities and the target company a “co-registrant” in SEC filings for a de-SPAC transaction—holding management teams liable for the accuracy and completeness of disclosures;
  • Remove the availability of safe harbors for forward-looking statements and require additional disclosure on the use of projections and who prepared them to address concerns about their overall reliability;
  • More closely align financial statement requirements for the target company with traditional IPO requirements by no longer factoring in whether the SPAC has filed its first annual report when determining the number of years required;
  • Deem a financial advisor that facilitates the de-SPAC transaction to be a statutory underwriter subject to a due-diligence defense;
  • Require a disclosure from the SPAC about whether the SPAC merger is advisable and in the best interests of the SPAC and its shareholders and if any outside party prepared a fairness report;
  • Require a minimum period of time for proxy materials to be disseminated to shareholders prior to the proxy vote (generally 20 days);
  • Require a re-determination of smaller reporting company status upon closing of a de-SPAC transaction, similar to a traditional IPO.

Preparing to go public via a SPAC merger

Going public

The target company will need to consider numerous cross-functional impacts for going public and being public, such as:

Accounting and reporting considerations

A target company in a SPAC merger normally will need to prepare itself for being a public company within a few months. This timeline is typically shorter compared to a traditional IPO for substantially the same preparation, due diligence, prospectus-drafting and SEC engagement and oversight. Public company readiness for a target company should cover cross-functional topics such as: accounting and financial reporting, finance transformation, financial planning and analysis, tax matters, internal controls and internal audit, human resources (HR) and compensation, treasury, enterprise risk management, technology and cybersecurity.

Given the typical time frame under which the merger occurs, a robust, cross-functional project plan should be prepared and owned by a project management office and a project leader.

A SPAC merger normally requires multiple steps of legal/equity restructuring that impacts the tax status and considerations of the target company.

The target company may qualify for reporting accommodations provided to a smaller reporting company (SRC) or an emerging growth company (EGC) in certain circumstances. Such relief can meaningfully impact the time and effort required to consummate the transaction. Target companies should discuss these accommodations with their advisors early in the readiness preparations.

The target company’s financial statements must be in compliance with SEC reporting requirements. Financial statement disclosure areas with substantial uplift, including earnings per share, segments, adoption of new standards, as well as quarterization, among others, can increase the time and effort required to prepare compliant financial statements.

The target company’s annual and interim financial statements must be audited and reviewed based on PCAOB standards, which can add additional time and complexity to historical audits as compared to AICPA standards.

The accounting acquirer is the entity that has obtained control of the other entity (i.e., the acquiree) and may be different from the legal acquirer. If the target company is determined to be the accounting acquirer, the transaction will be treated similar to a capital raising event (i.e., a reverse recapitalization). If the SPAC is determined to be the accounting acquirer, purchase accounting will apply and the target company’s assets and liabilities will require a valuation to be stepped-up to fair value (i.e., a forward merger).

Pro forma financial information is typically required and will provide a comprehensive view of the SPAC merger. The basis of presentation for the pro forma information is dependent on the expected accounting treatment of the transaction and typically includes considerations for public shareholders’ redemptions, secondary transactions and impact from any tax status change from the SPAC merger. Early coordination amongst all parties will be critical.

The target company must prepare a MD&A disclosure for all periods presented in the financial statements so that investors understand the target company’s financial condition and results of operation. MD&A disclosures usually require extensive data analysis and generally contain sensitive financial and operating information.

The target company must prepare a comprehensive discussion of its business intended to help investors evaluate the company’s equity story. This disclosure typically covers the company’s business model and strategy, principal products and services, markets served, and prospective opportunities, among other disclosures about the nature and scope of its operations. The company must also disclose the material risks that could adversely affect its business to help investors understand the uncertainties and exposures inherent in the company’s operations and industry.

A Form 8-K with equivalent information that would be required in a Form 10 filing of the target company (commonly referred to as the “Super” 8-K) must be filed with the SEC within four business days of closing.

The bottom line

SPACs continue to be a path to liquidity for many companies. The SPAC merger process with a target company may be completed in as little as three to four months, which is substantially shorter than a typical traditional IPO timeline. Accordingly, a target company must accelerate public company readiness well in advance of any SPAC merger. Further, given the compressed timeline of a SPAC merger, project management is essential in order to reduce execution costs, increase project efficiencies, and provide working group participants with enhanced accountability and transparency.
