Investment banking's role in buy-side transactions is multifaceted and often shrouded in a degree of complexity that the general public doesn't fully appreciate. Whether investment banks make direct solicitations to potential buyers for buy-side deals is not a simple yes-or-no answer; it's nuanced and depends heavily on the specific circumstances, the nature of the deal, the relationship between the bank and the potential buyers, and regulatory considerations.
To understand this fully, it's crucial to delineate between the different services investment banks offer in the context of mergers and acquisitions (M&A). When representing the seller (the sell-side), investment banks are clearly and aggressively involved in reaching out to potential buyers. Their mandate is to maximize the value received by the seller, which inherently requires identifying and engaging with a wide pool of qualified bidders. This process typically involves creating a confidential information memorandum (CIM), reaching out to a pre-selected list of potential acquirers, managing the due diligence process, and negotiating the final transaction terms. In this scenario, customer calls are not only commonplace but a fundamental aspect of the bank's responsibilities.
However, when acting on behalf of a buyer (the buy-side), the dynamic shifts significantly. The investment bank's primary objective is to find a suitable acquisition target for their client, the buyer. Whether they "make customer calls" in the same proactive way as in a sell-side engagement is less direct and more strategic.

One key aspect to consider is the confidentiality surrounding buy-side mandates. Unlike sell-side deals, which are eventually publicized, buy-side engagements often operate under a cloak of secrecy. A buyer might not want their competitors to know they're actively seeking acquisitions, as this could impact their stock price, raise the value of potential targets, or signal strategic intentions they prefer to keep private. Consequently, investment banks are generally more discreet in their approach. They're less likely to blast out information indiscriminately to a broad range of potential sellers.
Instead, buy-side investment banks typically leverage their existing network of contacts, industry knowledge, and proprietary databases to identify potential targets that align with their client's acquisition criteria. This often involves internal research, analyzing market trends, and leveraging relationships to gather intelligence on companies that might be a good fit. The initial outreach, if any, is often extremely targeted and indirect. It might involve attending industry conferences, engaging in general conversations with industry players, or utilizing intermediaries to gauge interest without explicitly revealing the identity of their client or the specific nature of the buy-side mandate.
Direct "customer calls" in the sense of actively soliciting companies to be acquired are less common for several reasons. First, it could be perceived as aggressive or disruptive, potentially damaging relationships with potential targets, especially if the target is not currently considering a sale. Second, it could inadvertently reveal the buyer's intentions, jeopardizing the confidentiality of the engagement. Third, it could lead to a flood of unsolicited offers, overwhelming the buyer and making it difficult to identify genuinely attractive opportunities.
That said, there are instances where a buy-side investment bank might make more direct contact. This could occur if the bank has a strong existing relationship with a particular company that aligns perfectly with the buyer's strategic objectives. In such cases, a carefully crafted and confidential approach might be warranted. Alternatively, if the buyer has a very specific and unique set of criteria for an acquisition target, the bank might engage in more proactive outreach to companies that meet those requirements. However, even in these situations, the approach is typically highly controlled and strategic, with a strong emphasis on maintaining confidentiality and protecting the buyer's interests.
Furthermore, regulatory considerations play a role. Investment banks are subject to strict regulations regarding insider information and conflicts of interest. If a bank has inside information about a company, it's restricted from using that information to benefit its clients in a buy-side engagement. This further limits the extent to which they can directly solicit companies for potential acquisition.
Another factor to consider is the size and nature of the deal. For smaller, less publicized deals, investment banks might be more willing to engage in proactive outreach to potential targets. In contrast, for larger, more high-profile transactions, the approach is likely to be more discreet and targeted.
In conclusion, while investment banks certainly play a critical role in identifying and engaging with potential acquisition targets in buy-side deals, they don't necessarily make "customer calls" in the same overt way they do on the sell-side. The approach is more nuanced, strategic, and heavily influenced by the need for confidentiality, regulatory considerations, and the specific circumstances of the deal. They leverage their network, industry knowledge, and research capabilities to identify potential targets and then carefully craft their outreach strategy to maximize the chances of success while protecting their client's interests. The focus is on finding the right target, not just any target, and maintaining the utmost discretion throughout the process. The subtle art of identifying and courting potential targets without raising red flags is a key differentiator between successful and unsuccessful buy-side advisors.
