Best-Efforts Offering

A best-efforts offering is an underwriting structure in which the bank acts as a broker or agent rather than as a principal guarantor. The bank commits to “best efforts” to sell the shares at the stated price but does not guarantee that any shares will be sold or that any minimum amount of capital will be raised. If demand is soft, the offering can close with less capital than the company had hoped—or, in some jurisdictions, can be cancelled entirely if subscriptions fall below a stated minimum.

Firm commitment versus best efforts

The standard underwriting arrangement in a large secondary offering is a firm commitment: the bank buys all the shares from the company at a fixed price (minus commission), then resells them to institutional and retail investors. If demand evaporates and the bank ends up holding shares, tough luck for the bank—the company got its money anyway. The company bears no capital risk.

In a best-efforts offering, the bank does not buy the shares upfront. Instead, it acts as agent: it finds buyers for the company’s shares, takes a commission on each sale, and remits proceeds to the company. If the bank can only find buyers for 60% of the offering, the company gets 60% of the capital it wanted. The bank’s risk is minimal (it makes a commission on what sells), but the company’s risk is substantial.

This structure is common in smaller IPOs, SPAC related offerings, and offerings in emerging markets where demand is uncertain. It is rare in large-cap secondary offerings because institutional investors and underwriters both prefer the certainty of firm commitment.

The mechanics and minimum-subscription clauses

A best-efforts offering typically specifies a minimum subscription threshold—e.g., “the offering will not close unless at least $10 million of shares are subscribed.” If the bank can only secure $8 million in demand, the offering is cancelled, all subscription funds are returned to investors, and the company gets nothing.

This protection is critical for investors. Without a minimum, a company could launch an offering for $50 million, actually only raise $5 million, and then proceed with whatever capital it scraped together—leaving investors who committed early uncertain about whether their money would be deployed as intended.

The subscription period is typically longer in a best-efforts offering than in a firm-commitment offering. Where a firm commitment might close within 10 days, a best-efforts offering might remain open for 2–4 weeks, giving the bank time to canvass a wider investor base and build demand slowly.

Once subscriptions close and the minimum is met, the offering closes and settlement occurs 1–2 business days later. The company receives its funds minus the bank’s commission, which is often 5–7% of the capital raised (higher than the 2–4% in a firm-commitment offering, since the bank is taking more risk in terms of reputational damage if the offering fails).

Why companies use best efforts

The primary reason is cost and expediency for smaller or riskier companies. An IPO or secondary offering by a large company involves extensive due diligence, registration with the Securities and Exchange Commission, and a formal prospectus. A best-efforts offering can, in some cases, proceed under a lighter regulatory framework (e.g., Regulation A in the US or AIM admission in the UK), avoiding the cost and delay of a full registration.

A second reason is market conditions. If a company’s fundamentals are weak or its sector is out of favour, a traditional firm-commitment underwriter might demand a steep discount or refuse to participate. A best-efforts bank, by contrast, is not bearing the risk of holding unsold shares, so it may be willing to try to raise capital at a less attractive price point. The company keeps its pricing power.

A third reason is flexibility. A company might launch a best-efforts offering with an ambitious target (e.g., $100 million) but with a lower minimum (e.g., $20 million). If demand is strong, it can expand the offering; if weak, it can close at the minimum and use the smaller capital base to fund a scaled-back plan.

Investor protection and timing risk

Investors in a best-efforts offering face two risks that don’t exist in a firm-commitment offering.

First, capital risk: if subscriptions are weak, the offering may close with less capital than expected, and the company’s business plan may be impaired. An investor who committed to buy shares at $15 in a hoped-for $100 million raise might end up in a company that only raised $25 million—materially different risk profile.

Second, timing risk: the subscription period is longer, meaning the company (and early subscribers) don’t know for weeks whether the offering will succeed. Stock prices can move dramatically in that window. An investor who subscribed at $15 might face a resale market at $12 if sentiment shifts, or conversely might be unable to sell if the shares are in escrow pending final closing.

To mitigate the capital-risk problem, best-efforts offerings almost always include a minimum-subscription condition (as noted above). To mitigate timing risk, some offerings include an “all-or-nothing” clause: if the minimum is not met by a certain date, the offering is automatically cancelled and funds are returned.

Best efforts versus rights issues and accelerated bookbuilds

A rights issue is typically firm-committed (the underwriter guarantees full take-up) and is pro-rata to existing shareholders. A best-efforts offering is non-pro-rata (open to new investors) and does not guarantee capital. An accelerated bookbuild is always firm-committed and always guarantees capital; it trades capital certainty for speed and excludes retail investors.

A best-efforts offering sits lower on the certainty spectrum: it is cheaper than a firm-commitment secondary (the company avoids registration costs), but it also cannot assure the company of its capital target. It is most suitable for smaller, higher-risk companies that cannot command a firm-commitment underwriter and are willing to accept the risk of a shortfall in exchange for lower upfront costs.

Regulatory context

In the US, best-efforts offerings are typically conducted under Regulation A, which allows issuers to raise up to several million dollars without full SEC registration. The prospectus is simpler and the timeline is shorter than a full Reg S or Reg A+ offering.

In the UK, best-efforts offerings are less common but sometimes used for small AIM admissions. In Canada and Australia, they are used for small venture-capital raises and for SPAC related offerings.

The downside for the issuer is that best-efforts offerings attract a different investor base: smaller, often more retail-focused, and with less institutional commitment than a firm-commitment offering. This can result in a less liquid, more volatile market for the shares post-listing.
