Sponsor Finance Counsel in 2026: On Just 6.0% of Sponsor Deals

A sponsor general counsel who asks for finance lawyers for private equity sponsors expects a deep, specialized bench. The deal record says the bench is thinner on sponsor work than on bank, power or real estate work. Sartori & Partners data show banking and finance lawyers on 6.0% of the 3,326 sponsor deals dated in the 12 months to October 2026. On bank deals the same practice appears on 15.8%, on power and renewables deals on 12.0%, and on real estate deals on 9.6%. Yet sponsors are not a side line for finance teams: they were on 6.6% of the practice's deals. This report sets those two readings side by side and draws the consequences for anyone choosing debt counsel on a buyout, a fund or a portfolio company.

Each figure is a share of one sector's dated deals that had a banking and finance lawyer on them. Many deals carry no practice label, and one deal can carry several, so the shares inside a sector overlap and are read one at a time. Read across sectors, the gap is plain. The finance share of bank deals is 2.6 times its share of sponsor deals, and its share of power and renewables deals sits 6.0 points above its sponsor share. Across all dated deals, Sartori & Partners figures put banking and finance lawyers on 6.3%, so a sponsor deal is no more likely to involve a finance lawyer than the average deal in the record.

The comparison carries a practical warning. Across the record, sponsor work that carries a finance label is modest in volume, whatever a firm's sponsor credentials. When a mandate turns on the debt package, ask the firm to show finance-led sponsor matters, not only the sponsor deals its corporate teams ran.

Turn the lens around and sponsors matter to finance teams. Of the 3,053 banking and finance deals in 12 months, 201 involved financial sponsors. That is the practice's fourth client sector by share, after banks at 17.8%, power and renewables at 7.8% and real estate at 6.8%. Sponsors are on 6.9% of all dated deals, so the finance practice works for them at close to the market rate, 0.3 points under it. Banks are different: they reach 17.8% of finance deals against 7.1% of the market.

For a sponsor this is a matter of weight at the table. A finance practice whose deals involve banks far more often than sponsors will staff and price sponsor mandates around that mix. Ask how many of the partners proposed for your financing acted for a sponsor in the last 12 months, and on which side of the loan.

In the Sartori & Partners deal record, private equity lawyers worked on 32.8% of sponsor deals, funds and investment management lawyers on 10.8% and corporate and M&A lawyers on 9.1%. The deal types follow: private equity deals are 26.6% of the sector's work, M&A 17.4% and fund formation 10.4%. Leveraged and acquisition finance appears on 5.6% of sponsor deals, 3.5 times its 1.6% share of all dated deals.

Inside the finance practice, across every client sector, banking and lending deals are 44.5% of the work and leveraged and acquisition finance 23.4%. The record has no type split for the practice's sponsor deals alone, so the two readings stay separate. The point for a buyer is staffing: on a sponsor deal the finance mandate can sit next to a private equity team that owns the client. Agree up front who leads the debt workstream and who signs off on it.

Banking and finance deals rose 12.1% on settled 12-month windows, from 2,710 to 3,039. Sponsor deals rose 8.9% over the same windows, from 3,056 to 3,329. The whole deal record rose 10.6%, from 43,590 to 48,216. These are separate readings of two groups of deals; the record holds no trend for sponsor deals with finance lawyers on them.

The lateral market for finance lawyers is busy too. Banking and finance lawyers changing firms rose 14.1%, 1,766 moves to 2,015, and partner moves rose 10.6%, 546 to 604. Among lawyers whose own focus is sponsors and who moved firm, 19.7% practice banking and finance, an index of 141 against the market. When the finance partner you rely on can be hired away, put a named second partner in the engagement letter.

Two firm lists answer two questions. The sponsor list ranks advisers on all sponsor deals, of every type and practice, and Kirkland & Ellis heads it in the 251-400 band of deals advised. The finance list ranks advisers on all banking and finance deals, for every client sector, and Latham & Watkins heads it in the 151-250 band. No list exists for finance work on sponsor deals alone.

The firms on both lists are Latham & Watkins, Jones Day and Simpson Thacher & Bartlett. They combine a large volume of sponsor work with a large volume of finance work, though the lists do not show how much the two overlap inside each firm. Use them as a first call for a combined acquisition and financing mandate, and ask each to name the finance partners who acted for sponsors.

43.2% of the sector's deals were handled with lawyers in New York, 29.5% with lawyers in London and 24.0% with lawyers in Washington. One deal counts in every city whose lawyers worked on it, so these shares are not added. The lateral flow of finance lawyers looks different. Banking and finance lawyers who changed firms joined New York at an index of 145 against the market, Chicago at 92 and Washington at only 50. A sponsor that wants its finance counsel in Washington will find relatively few movers there and may need to draw on a New York team for the debt work.

Treat finance capacity as a separate test of any sponsor panel. With banking and finance lawyers on 6.0% of sponsor deals, a firm's sponsor volume says little about the depth of its debt bench. Ask for the finance partners by name and for the matters they led, and check them against the finance list as well as the sponsor list.

Know where you sit in the finance team's book. Sponsors are 6.6% of banking and finance deals, against 17.8% for banks, so banks are often the larger relationship for the team you hire. Ask about conflicts with your lenders early. And lock in continuity: finance lawyers are changing firms at a faster pace, with 2,015 moves in the latest settled 12 months, so a named alternate partner protects a deal timetable.
