From the preface

The ownership equation

Private equity connects financial analysis with the responsibilities of ownership. An investment thesis must survive the purchase price, the financing, the demands of operating a business, and the eventual need to realize value. Studying those elements together gives the reader a stronger foundation than studying a valuation model or a famous transaction in isolation.

This book develops that foundation in twenty-five chapters. It begins with the ownership model and fund relationship, follows an investment from sourcing to exit, and then examines specialist strategies, portfolio access, governance, performance, and the investment organization. Selected cases illustrate how business economics, capital structures, and owner decisions interact. Worked examples and practical tools support the narrative.

The intended audience includes students, analysts, entrepreneurs, and readers seeking a disciplined understanding of private markets. The chapters explain concepts before applying them. The emphasis is on clear reasoning, transparent assumptions, and the connection between analysis and decisions.

Private Equity Research Companion · Part I

22 industry studies

The companion opens with an in-depth study of each part of the industry, backed by 32 technical exhibits: worked examples, diligence checklists and case studies.

01Leveraged Buyouts (LBOs)The leveraged buyout is the core product of private equity. A sponsor buys control of a company with a small slice of equity and a large slice of borrowed money, and repays that debt from the company's own cash flow. Everything else in this industry (growth equity, secondaries, continuation vehicles, private credit) either grew out of the LBO or exists to serve it.+ 2 exhibits 02Growth EquityGrowth equity means buying a significant, usually minority, stake in a proven, growing, often founder-led company. Little or no leverage is used. Returns come from revenue and earnings growth, not financial engineering. It sits between venture capital (unproven models, high loss rates) and buyouts (control, leverage, mature cash flows), and borrows tools from both.+ 1 exhibit 03Venture Capital vs. Private Equity: The Boundary and Crossover FundsVenture capital and buyout private equity are both "private equity" in the broad sense: illiquid, closed-end funds, 2-and-20 economics, GPs and LPs. But they rest on opposite statistical foundations. Buyouts are built on avoiding losses. Venture is built on finding outliers. The space between them (late-stage venture, growth equity, crossover investing) is where the 2020–2022 cycle produced both the biggest fortunes and the biggest losses of the past two decades.+ 1 exhibit 04Distressed Investing and Special SituationsDistressed investing means buying the securities or assets of companies in or near financial distress, usually debt trading below ~70–80 cents on the dollar or yielding more than ~1,000bp over Treasuries, in order to profit from recovery, restructuring, or control. Special situations is the wider bucket of complex, event-driven, capital-structure-sensitive investments: rescue financings, DIP loans, liability-management transactions, orphaned assets, litigation-driven claims, and structured equity for stressed companies. These strategies are counter-cyclical, legally intensive, and, in the hands of experts, among the most consistently profitable in private markets.+ 2 exhibits 05Secondaries and GP-Led Continuation VehiclesIn one line: Secondaries is the market for buying and selling existing private-markets exposure. It turns a 10–12 year illiquid commitment into something that can be priced and sold. Over the last decade it has gone from a niche, distressed-seller business to the main source of liquidity for LPs and GPs.+ 2 exhibits 06InfrastructureIn one line: Infrastructure investing means owning long-lived, essential, usually monopoly-like physical assets. Examples are toll roads, airports, utilities, pipelines, towers, fibre, data centres and renewables. Their cash flows are tied to contracts, concessions or regulation. Done well, it is the private-markets asset class closest to an inflation-linked bond with equity upside. Done badly, it is a leveraged bet on traffic, regulators and refinancing markets.+ 2 exhibits 07Real Estate Private EquityIn one line: Real estate private equity (REPE) buys, improves, finances and sells income-producing property, or builds it. Returns are driven by four levers: income (NOI), NOI growth, leverage, and cap-rate movement. The last one is mostly outside the manager's control, and it has created and destroyed more wealth in the asset class than any other.+ 2 exhibits 08Private Credit and Direct LendingIn one line: Private credit is non-bank lending by funds, BDCs and insurance balance sheets, negotiated directly with borrowers and held to maturity rather than syndicated. It grew from a post-GFC niche into a ~$1.7–2tn+ asset class (~, reported industry estimates). It now competes head-on with the leveraged-loan and high-yield markets and is the main financing source for middle-market LBOs.+ 3 exhibits 0909. Fund of Funds and Co-InvestmentTwo opposite answers to the same problem: how does an LP get good private equity exposure at an acceptable cost? A fund of funds (FoF) adds an intermediary layer, and an extra layer of fees, in exchange for diversification, access and expertise. Co-investment removes a layer by investing directly alongside the GP in specific deals, usually with no fee and no carry. Most sophisticated LP programs now combine the two, and the biggest FoF managers have become multi-strategy "private markets solutions" platforms that do both.1010. Sector Specialist FundsFor most of PE history, the default firm was a generalist: one fund, one investment committee, any industry with cash flow. Since the late 1990s, and especially since the 2010s, a large share of the industry's best returns and largest funds have come from sector specialists. Examples include Thoma Bravo and Vista in software, Welsh Carson and Consonance in healthcare, L Catterton and Roark in consumer, AIP and Arcline in industrials, and Stone Point and J.C. Flowers in financial services. Generalist megafirms responded by building sector verticals inside their platforms. This section covers why specialization works, where it fails, and how the five big sector playbooks differ.1111. Fundraising and LP RelationsRaising a fund is selling a 10–12 year blind-pool promise to the most sophisticated buyers in finance. The Limited Partnership Agreement (LPA) is that promise written down. This section covers how fundraising works, the economics in the LPA (2-and-20, the hurdle, the waterfall, the GP commitment), the institutional LP base, and how the relationship is managed once the money is in.12Deal Sourcing and ProcessWhere deals come from, how they are run, and how a sponsor gets from a teaser to a signed SPA without overpaying, losing the asset, or getting trapped by the paper.13Due DiligenceDiligence isn't about collecting facts. It's about testing the three to five things that must be true for the investment to work, and pricing or structuring around everything else.14LBO Modeling and ValuationPurpose. How private equity actually prices companies: the valuation toolkit (trading comps, precedent transactions, DCF, LBO), the mechanics that turn a headline enterprise value into the cheque the seller receives, and the return math (IRR, MOIC, attribution) that investment committees argue about. Written for practitioners — deal teams, IC members, LPs underwriting GPs, and lenders reading sponsor models.+ 4 exhibits 15Debt Financing and Capital StructurePurpose. How buyouts are financed: the instruments (revolvers, term loan A and B, first and second lien, unitranche, high-yield bonds, HoldCo PIK, preferred equity), how they are priced and documented (covenant-lite, EBITDA add-backs, call protection, incurrence baskets), how sponsors use them after closing (repricings, add-ons, dividend recaps), and how documentation flexibility turned into the liability management exercises (LMEs) that have redefined creditor rights since 2016.+ 5 exhibits 16Value Creation and Portfolio OperationsIn the 1980s, private equity made money from leverage. In the 2000s, from leverage plus multiple expansion. With rates above zero again and multiples no longer a tailwind, the money increasingly has to come from making companies better.17Exit Strategies"You make your money when you buy, but you only *get* your money when you sell." LPs are paid in cash (DPI), not in marked-up NAV. The exit is where every assumption in the investment case is finally tested.18Legal, Tax and Fund StructuringScope. How private equity funds are legally built and taxed: the limited partnership chassis, the jurisdictions (Delaware, Cayman, Luxembourg, Guernsey/Jersey, Ireland, UK), parallel funds and feeders, alternative investment vehicles (AIVs), blocker corporations for tax-exempt and non-US investors, carried interest taxation, and management equity plans (MEPs) at the portfolio-company level.19ESG, Regulation and PolicyScope. The regulatory perimeter around private equity in the US, EU and UK: SEC adviser regulation (the vacated 2023 Private Fund Adviser Rules, Form PF, the Marketing Rule, exam priorities), AIFMD II and SFDR in Europe, antitrust scrutiny of sponsors (2023 Merger Guidelines, HSR form changes, serial roll-ups, interlocking directorates), retail/401(k) access, healthcare and political scrutiny, the carried-interest tax debate, and ESG integration and its backlash.20History of Private EquityScope. How the industry evolved from Georges Doriot's American Research and Development (1946) to a ~$13–15 trillion (reported, broad "private markets" definition) asset class spanning buyouts, credit, infrastructure, real estate, secondaries, insurance balance sheets and retail evergreen funds — and the lessons each era taught.21Careers and Firm OrganizationHow a private equity firm is actually built: who does what, how people are paid, how carried interest is cut up, how investment decisions get made, and how talent enters and leaves the system. Written from the perspective of someone who has sat on both sides of the table: as a deal partner allocating carry and chairing IC, and as an LP diligencing "team stability" before writing a nine-figure check.+ 4 exhibits 22Performance MeasurementHow private equity performance is measured, why every metric can mislead, and how experienced LPs and GPs actually read a track record. Private markets have no daily price; returns are built from irregular, manager-controlled cash flows plus a manager-estimated NAV. Every number in a PPM is therefore a choice — of metric, of benchmark, of date, of gross vs net, of whether a credit line was used. Understanding those choices is the job.+ 4 exhibits
