Platform Acquisition Due Diligence: What Private Equity Sponsors Expect
A platform acquisition is the foundation of a private equity investment thesis. Unlike add-on acquisitions, where the buyer already has sector context and an operating business, a platform deal is the entry point. The stakes are higher, the diligence scope is broader, and the sponsor's expectations of the Transaction Services team reflect this.
The financial due diligence on a platform must validate not only current earnings quality but also the business's capacity to serve as the base for a buy-and-build strategy.
Earnings Quality with a Forward-Looking Lens
The Quality of Earnings analysis on a platform deal must go deeper than historical normalization. Sponsors are underwriting a 4-5 year hold period with a specific value creation thesis.
Run-rate EBITDA with conviction: The diligence team must clearly articulate the normalized EBITDA with a waterfall of adjustments that the sponsor can defend to their investment committee. Each adjustment needs supporting evidence, quantification methodology, and a confidence assessment.
Growth sustainability: Beyond run-rate, sponsors want to understand revenue momentum. Is recent growth organic or acquisition-driven? Is it coming from price, volume, or mix? What is the customer acquisition trend? Transaction Services teams increasingly provide revenue decomposition analysis alongside the traditional QoE.
Management adjustments scrutiny: Platform targets often present management-adjusted EBITDA with pro forma adjustments for planned initiatives (new hires, facility expansion, cost savings programs). The diligence team must independently assess whether these adjustments are credible, properly calculated, and likely to be achieved.
Scalability Assessment
A platform must be able to absorb future add-on acquisitions without operational breakdown. The financial due diligence should address scalability indicators.
ERP and financial systems: Assess whether the target's ERP (SAP, Oracle, NetSuite, Sage) can accommodate additional entities post-acquisition. A platform running a single-entity QuickBooks installation will require a system migration before any add-ons can be integrated. This is a material cost and risk that the sponsor needs to understand.
Chart of accounts structure: A well-designed chart of accounts facilitates consolidation of add-ons. A poorly structured COA creates mapping challenges with every subsequent acquisition. Evaluate the COA's granularity and logical structure as part of the financial infrastructure assessment.
Financial reporting capabilities: Can the target produce management reporting at the speed and granularity the sponsor requires? Private equity sponsors typically expect monthly reporting within 10-15 days of period end. If the target currently takes 30+ days, the gap needs to be quantified in terms of remediation cost.
Carve-Out Considerations
Many platform acquisitions involve a carve-out from a larger corporate parent. This adds significant complexity to the financial due diligence.
Standalone cost structure: The target's financials as a division or subsidiary may not reflect standalone operating costs. Shared services (finance, HR, IT, legal), corporate allocations, and intercompany transactions must be replaced with arm's-length standalone costs.
Transitional service agreements (TSAs): Identify which services the seller will provide post-close and for how long. Quantify the cost of each TSA and the eventual standalone replacement cost. TSA duration and exit costs directly impact the buyer's early-period cash flows.
Stranded costs: When a division is carved out, the parent may retain costs that were previously allocated to the target. Conversely, the target may need to build capabilities that were previously provided by the parent. Both sides of this equation must be quantified.
Working Capital and Cash Conversion
Working capital normalization: Platform deals require careful net working capital analysis because the target's working capital patterns will serve as the baseline for future add-on comparisons. Getting the normalized working capital wrong on the platform deal creates problems on every subsequent add-on.
Cash conversion assessment: Sponsors want to understand how efficiently earnings convert to cash. Analyze the relationship between EBITDA and free cash flow over the trailing 12-36 months. Identify any structural gaps (high capex intensity, long working capital cycles, significant non-cash charges) that affect cash available for debt service and add-on acquisitions.
Data Quality and Accessibility
The quality and accessibility of the target's financial data is itself a diligence finding. A platform with clean, well-organized financial data will be easier to manage, report on, and integrate add-ons into.
Assess data quality across dimensions: completeness (are all material accounts and entities represented?), accuracy (do sub-ledgers reconcile to the GL?), timeliness (how current is the available data?), and accessibility (can data be extracted efficiently from the ERP?).
What Sponsors Remember
The Transaction Services team's performance on the platform deal shapes the relationship for the entire hold period. A thorough, well-structured analysis that anticipates the sponsor's questions and provides clear, defensible conclusions positions the team for the add-on mandates that follow.
Sponsors value teams that deliver efficiently without cutting corners, provide commercially relevant insights beyond the numbers, and communicate findings clearly. The platform engagement is the audition for a multi-year advisory relationship.
