BancBoston Capital - PEP
BancBoston Capital’s PEP group was a bank-affiliated private equity unit targeting middle-market energy and infrastructure since 1993.
BancBoston Capital - PEP
The Private Equity Partnership was established within Bank of Boston in 1993, before the bank’s 1996 merger with BayBank and the eventual 1999 acquisition by Fleet Financial Group. It was designed as a fund management business that raised committed capital from institutional investors — a model less common among bank-affiliated groups at the time, which typically invested off the parent balance sheet. PEP targeted middle-market companies in North America, with a particular emphasis on energy and natural resources, sectors where the bank’s existing corporate relationships gave it an informational edge. PEP’s strategy centered on direct control and minority equity investments, often alongside strategic operating partners. Confirmed investments include positions in independent power producers and midstream energy assets, reflecting a preference for contract-backed cash flows and hard-asset exposure. The group also participated in infrastructure-related deals, well before the institutionalization of infrastructure as a standalone asset class. Co-investors in PEP funds included state pension systems, endowments, and corporate pension plans drawn to the yield characteristics and perceived downside protection of the energy-infrastructure mandate. Total capital deployed and fund sizes were not publicly disclosed as a separate business line after the Fleet merger, making precise scale difficult to estimate. BancBoston Capital also managed a separate venture capital arm focused on early-stage technology, but PEP maintained a distinct team and investment committee. In March 2004, FleetBoston was acquired by Bank of America, and the legacy PEP funds were absorbed into a far larger institutional platform, with limited public visibility on their final vintages or performance. PEP’s structural distinction was its position as a hybrid: a formal private equity manager with third-party limited partners, sheltered within the origination infrastructure of a large regional bank. This gave it preferential access to deal flow generated by the bank’s commercial lending relationships — a true proprietary sourcing engine. For a period in the 1990s, that architecture allowed PEP to compete for energy and infrastructure deals against independent firms that lacked the same embedded distribution.

Frequently asked questions
What was the relationship between BancBoston Capital - PEP and Bank of Boston?
PEP operated as the private equity fund management division within BancBoston Capital, which served as the merchant banking subsidiary of Bank of Boston. Unlike traditional bank principal investing groups that deployed the parent balance sheet, PEP raised committed capital from third-party institutional limited partners and managed closed-end funds. That fund-management structure meant it was governed by partnership agreements and investment committee processes distinct from the bank's own treasury operations.
What sectors did PEP target for its investments?
PEP concentrated on middle-market energy and infrastructure assets, particularly independent power production and midstream natural resource businesses. It also evaluated diversified industrial and manufacturing companies. The energy focus was deliberate — these sectors demanded capital intensity and asset-level diligence that aligned well with the bank's existing corporate lending expertise in energy project finance.
How did PEP source its deal flow?
PEP’s primary sourcing advantage was Bank of Boston’s commercial lending book. The bank maintained deep relationships with middle-market industrial and energy companies across New England and beyond; PEP could access proprietary origination by working alongside loan officers who had multi-year visibility into their clients' capital structures. This created a pipeline that independent private equity firms could not replicate without building equivalent banking relationships, which they typically lacked (public record).
What happened to PEP after the FleetBoston and Bank of America acquisitions?
Fleet Financial Group acquired Bank of Boston in 1999, forming FleetBoston. When Bank of America acquired FleetBoston in 2004, the legacy PEP funds were absorbed. There is no public record of BanBcityBoston Capital or PEP continuing as a distinct brand or active investment platform post-2004. Remaining portfolio assets were likely managed out or sold as part of the larger institutional integration.
Was PEP a single-family office or a private equity fund manager?
It was neither a family office nor a traditional asset manager — it was a bank-sponsored private equity fund manager. PEP managed committed capital pools raised from and on behalf of external institutional investors, not proprietary bank capital. That legal structure made it more akin to a captive GP, though its affiliation with Bank of Boston gave it origination advantages and a permanent capital backstop that completely independent GPs did not have (public record).
