Technology Debt and EBITDA: What PE Sponsors Are Getting Wrong

Private equity firms are sophisticated buyers. They model working capital cycles, dissect customer concentration, and pressure-test management assumptions with precision. But the same firms that scrutinize every line of the income statement often accept IT due diligence that amounts to little more than a conversation with the CTO and a quick look at the major vendor contracts. The result is a systematic blind spot — and it's costing sponsors real money.

Technology debt accrues the same way financial debt does: through deferred decisions. An infrastructure refresh pushed to next fiscal year. A CRM customization that made sense in 2019 but now prevents the integrations the business needs to scale. An ERP that runs critical operations but requires five FTEs to maintain because it was never properly implemented. These aren't line items on the balance sheet, but they generate costs that flow directly through EBITDA — in elevated support burdens, vendor lock-in premiums, and the opportunity cost of capabilities the business can't access.

In our experience assessing technology environments for portfolio companies, the average mid-market business acquired without detailed IT diligence carries between $800K and $2.5M in unmodeled technology-related costs over the first three years post-close. That's before accounting for the integration costs required to merge IT environments in platform transactions, or the deferred modernization spend required to unlock the operational improvements underpinning the investment thesis.

The most common miss is what I call the "maintained vs. invested" distinction. Sponsors ask whether technology is maintained — is it functional, is it supported, are there active vendor contracts? What they rarely ask is whether technology has been invested in — has it kept pace with the business, does it enable the operating model, and could it support the growth trajectory embedded in the model? A business that has maintained its technology at the expense of investing in it looks fine in diligence and breaks under growth.

The fix is straightforward but requires changing the scope of what gets diligenced. Technology assessment needs to move beyond infrastructure inventory and vendor contract review into three additional domains: architecture adequacy relative to the investment thesis, total cost of ownership modeling for the next 36 months including deferred spend, and integration risk analysis for any platform roll-up strategy.

The best PE-backed technology transformations I've seen treat the first 100 days post-close as an opportunity to build the IT roadmap that will support the value creation plan — not to minimize IT spend. Technology isn't just a cost center on the journey to exit. It's either an accelerant or a drag. The difference is determined well before the transaction closes.
