How to Choose the Right Underwriter for Your IDX Listing

Selecting an underwriter is one of the most consequential decisions a company makes in the IPO process. The underwriter shapes how the company is presented to investors, manages the bookbuilding, and determines the pricing range that sets the terms of the offering. Yet many Indonesian companies approach this selection without a clear framework for evaluation.

This article sets out what to look for, what to ask, and how to think about the relationship before signing a mandate letter.

What an underwriter actually does

An underwriter, or penjamin emisi efek, is an OJK-licensed securities firm that underwrites the offering. Its responsibilities include: preparing and co-signing the prospectus, managing the bookbuilding process, marketing the offering to institutional and retail investors, setting and stabilising the offering price, and taking on regulatory responsibility for the accuracy of the prospectus alongside the company.

The underwriter is compensated through an underwriting fee, typically expressed as a percentage of the gross proceeds. In the Indonesian market this generally ranges from 2% to 4% for mid-market offerings, though the range varies by deal size and complexity.

The distribution network is more important than the brand name

For a listing on Papan Pengembangan, the most relevant criterion is the underwriter's distribution reach into the investor base most likely to subscribe to your offering. This is not always the most prestigious firm name.

Large integrated securities houses have broad retail distribution networks, which matters for companies targeting retail investor participation and the free float requirements. Mid-tier boutique underwriters may have stronger relationships with specific institutional investor segments, family offices, or regional investor networks that are better suited to certain deal profiles.

Ask each underwriter to explain specifically: which investors they expect to approach for your offering, how many of those investors they have active relationships with, and what allocations those investors typically take in comparable deals. A confident, specific answer to these questions is a better indicator of distribution capability than a firm's general reputation.

Sector experience matters, but not as a credential

An underwriter that has taken multiple companies in your sector public will understand the standard investor objections, the appropriate valuation benchmarks, and the comparable transaction set that will frame your pricing. This is genuinely valuable.

However, sector experience should be evaluated as a capability, not accepted as a credential. Ask the underwriter to walk you through a recent comparable transaction: how was the company valued, what was the bookbuilding experience, how did the stock trade in the first six months after listing? The quality of that explanation tells you more than a list of deal names.

The research analyst relationship

After listing, the underwriter's research analyst will typically initiate coverage on your company. The quality and credibility of that research, and the analyst's standing among institutional investors who read it, affects secondary market liquidity and institutional interest over time.

Before signing a mandate, ask which analyst would cover your company post-listing. Request to meet that analyst as part of the due diligence process. Understand how they think about valuation in your sector and whether their view of your business is credible and well-informed.

Terms to negotiate

The mandate letter sets out the commercial terms of the underwriting engagement. Key terms to review carefully include:

• The underwriting fee and any incentive fee structure.
• The lock-up period for the underwriter's own position, if any.
• The greenshoe or overallotment option, which gives the underwriter flexibility to stabilise the price post-listing.
• The exclusivity period, which prevents the company from engaging other advisors or underwriters during preparation.
• The conditions under which the underwriter can withdraw from the mandate, and what obligations remain if they do.

All of these terms are negotiable. The company has more leverage in this negotiation before signing than it will have afterward. Engaging an independent advisor before finalising the mandate significantly improves the quality of that negotiation.

A practical note on timing

The underwriter selection typically happens six to twelve months before the intended listing date, after the company has already addressed the major readiness gaps. Selecting an underwriter too early, before the company's financial and governance house is in order, can create pressure to list before the company is genuinely ready. The underwriter has an incentive to complete a transaction. The company's interest is in completing the right transaction at the right time.
