How Sponsors Choose Their Banks: Wallet Allocation

Introduction

Across 1,590 loans that financed sponsor-backed leveraged buyouts between 1993 and 2005, Ivashina and Kovner found that private equity firms with stronger bank relationships borrowed at lower spreads and with looser covenants, and that banks priced those loans partly to cross-sell other fee business. That is the bargain at the center of sponsor coverage, seen from the client's side. A bank prices its lending to win future mandates; the sponsor decides which banks receive those mandates and keeps track of who earned them. That wallet allocation is run by a sponsor's deal partners and its head of capital markets, who hand out lead roles, co-manager slots, advisory mandates and revolver commitments across many transactions at once. It explains why balance-sheet banks accept thin returns on relationship lending, why a commitment honored in a closed market is remembered for years, and why lending still does not guarantee the advisory mandate a bank most wants.

A sponsor rarely hires one bank for a transaction. It allocates a set of roles, and the decisions sit in two places. Deal partners choose advisers on acquisitions and exits. The head of capital markets, a whole team at the largest firms, chooses the banks on financings across the portfolio, from acquisition debt to refinancings, repricings and dividend recaps. Because both see each bank's contribution over many deals, the choice on any single transaction reflects the account as a whole: the sponsor's mirror image of the wallet share a coverage team measures from the bank's side.

The roles differ in prestige, in workload and in pay:

Titles Versus Economics

Two levers give the sponsor more room than the table suggests. The first is the gap between titles and economics: a bank can appear on a cover page as a joint bookrunner while receiving a small share of the fee, so a sponsor can recognize many lenders publicly while concentrating the pay among two or three. The second is sequencing. A bank passed over for the lead on one financing may be promised a senior role on the next, or on the same company's exit. Why the bank listed first on the left runs the deal is explained in the equity capital markets guide's article on bookrunner roles.

Bank Group

The banks that lend under a company's credit facilities, usually including its revolving credit facility, and that expect to be considered for the company's fee-paying mandates in return. For a sponsor-owned company, the bank group is often the starting list for later refinancing, initial public offering (IPO) and sale roles.

Membership of that group is largely set at entry. A bank that declines the revolver on a new buyout weakens its claim to those later roles for the life of the investment, which is why coverage bankers rarely refuse one lightly.

The trade is easy to assert and harder to measure, because sponsors do not publish their allocations. Two kinds of evidence are available: academic studies of lending relationships and the underwriting disclosures a portfolio company makes when it goes public.

What the Research Finds

A broader study of corporate borrowers, not sponsor clients specifically, puts numbers on both halves of the exchange. Bharath, Dahiya, Saunders and Srinivasan found that a relationship lender had a 42% probability of providing a borrower's next loan, against 3% for a bank without the relationship, and that relationship lenders were also more likely to be chosen for debt and equity underwriting, although that effect was economically small. Lending reliably wins repeat lending; it wins underwriting and advisory work only at the margin. For a coverage banker, the lesson is that a loan earns a seat, not the lead.

Lineage: When the Lenders Became the Bookrunners

Lineage, the temperature-controlled warehouse operator controlled by investment firm Bay Grove, shows the overlap in a public document. Its July 2024 IPO prospectus priced shares at $78 and listed 21 joint bookrunners and eight co-managers. The underwriting section disclosed that affiliates of 14 of those bookrunners, including Morgan Stanley, Goldman Sachs, BofA Securities, J.P. Morgan and Wells Fargo, were lenders under Lineage's revolving credit facility and term loan. Net proceeds were estimated at about $4.2 billion, nearly all of it earmarked to repay bank debt, with roughly $2.4 billion going to a delayed-draw term loan provided by those first five banks, which were also the first five names on the cover.

The cover page does not show how the gross spread was divided, only that the 21 titles took in every bank in the lending group. As the prospectus noted, those lenders earned financing fees on the loans as well as the underwriting discount.

The sponsor's ledger has two entries that tell it most about a bank: whether it holds the unglamorous facilities, and whether it delivered in a closed market.

The Revolver as Currency

Every portfolio company needs a revolving credit facility for working capital, and it has traditionally come from banks. An undrawn revolver earns little and still uses the bank's capital, which is why bankers call it a loss leader. The bank holds it for what comes with it.

Ancillary Business

The fee-paying services a bank expects to win from a borrower because it provides lending on thin terms, such as hedging, cash management, bond and equity underwriting, and advisory work. It is what justifies a revolver that earns little on its own.

The revolver matters more as direct lenders take the term debt. On KKR's 2025 agreement to buy Karo Healthcare from EQT, Citigroup, Jefferies, BNP Paribas, HSBC and KKR Capital Markets had arranged a €1.275 billion package, including €1.1 billion of term loans, but KKR replaced the term debt with a unitranche of about €1.1 billion from direct lenders led by Apollo, Private Equity Wire reported. When the term loan goes to a fund, the facilities that can still sit with banks, such as the revolver, become the main way for a lender to stay in the company's bank group, and with it in line for the refinancing, IPO and sale roles that follow.

Who Delivered When Markets Closed

The heaviest entries concern commitments under stress. In 2008 Clear Channel Communications and its buyers, Bain Capital and Thomas H. Lee Partners, sued Citigroup, Morgan Stanley, Credit Suisse, Royal Bank of Scotland, Wachovia and Deutsche Bank in Texas and New York, accusing them of trying to avoid funding the committed debt; Clear Channel's announcement of the Texas suit sought damages substantially exceeding the $26 billion merger price. The parties settled in May 2008, the price fell to $36 a share from $39.20, and the buyout completed that July. The 2022 cycle tested the opposite behavior, when banks funded buyouts whose debt they could sell only at a loss, a story told in hung deals and syndication risk.

The trade has firm limits. Sell-side advice is the role a sponsor is least willing to hand out as a reward, because it sets the price of the exit, so sponsors often weigh buyer access and sector reach, or pick an adviser with no lending role. A bank that lends to a seller while hoping to finance its bidders also invites the conflicts examined in why banks cover a client type. The largest sponsors arrange part of their own financing through in-house capital markets desks, and where direct lenders fund the term debt, a bank's balance sheet is no longer the scarce resource it once was.

Within those limits, the coverage banker's levers are practical:

The size of the prize is set out in the sponsor fee pool. Inside any single relationship, the revolver is the clearest window: it pays the bank almost nothing and rarely makes a press release, yet holding it is what keeps a bank in the room when the mandates that do pay are handed out.
