IT Due Diligence Uncovers $1.2M in Hidden Risk for PE Acquisition

Challenge

The private equity firm had a signed letter of intent to acquire a healthcare technology company at a $45 million valuation. The target company operated a SaaS platform used by mid-sized healthcare providers for patient scheduling, billing integration, and clinical workflow management. On paper, the technology looked sound — the platform had steady revenue growth, low churn, and a loyal customer base.

But the PE firm’s operating partners had been burned before. A previous portfolio acquisition had revealed significant technical debt post-close, requiring $3 million in unplanned remediation that eroded the deal’s returns. This time, they wanted an independent, vendor-neutral assessment of the target’s technology stack, security posture, and operational readiness before committing capital.

The firm’s internal team had conducted a surface-level review of the technology but lacked the specialized expertise to evaluate infrastructure architecture, application security, HIPAA compliance depth, and the true cost of technical debt. With the deal timeline compressed to 45 days, they needed a partner who could deliver a rigorous IT assessment without delaying the close.

Solution

SBK assembled a focused diligence team and executed a comprehensive IT due diligence engagement in a tight three-week window. The scope covered five critical domains: infrastructure and architecture, application security, vendor and contract analysis, technical debt assessment, and integration cost modeling.

The infrastructure assessment revealed that the target company’s platform ran on a hybrid architecture — partially migrated to AWS, with legacy components still running on co-located servers. The partial migration meant the company was paying for both cloud and on-premises infrastructure simultaneously, with no clear timeline to complete the transition. SBK estimated that completing the cloud migration would require approximately 800 engineering hours and $180,000 in direct costs — a figure nowhere in the target’s financial projections.

The cybersecurity review was where the most significant findings emerged. SBK identified 23 critical security gaps, including unencrypted data at rest in two database environments, expired SSL certificates on internal APIs, inadequate access controls for production systems, and incomplete HIPAA audit trails. For a healthcare technology company handling protected health information, these weren’t theoretical risks — they represented potential regulatory exposure and breach liability.

SBK’s team also conducted a thorough vendor contract analysis, reviewing every third-party agreement for terms, pricing, and transferability. This uncovered $400,000 in annual vendor waste: duplicate analytics platforms purchased by different teams, an unused CDN contract that had auto-renewed for three consecutive years, and several SaaS tools where the company was paying for enterprise tiers while using only basic features.

The technical debt catalog documented code quality issues, outdated dependencies, and architectural decisions that would require remediation. SBK quantified each item with estimated hours and cost to remediate, providing the PE firm with a clear picture of post-acquisition investment requirements.

All findings were synthesized into an executive summary with a risk-adjusted valuation impact analysis. Each finding was categorized by severity, estimated remediation cost, and timeline. SBK provided specific recommendations for what should be addressed pre-close versus post-close, along with a 90-day integration technology roadmap.

Results

SBK delivered the complete IT due diligence report in three weeks, well within the deal timeline. The report ran 47 pages with an executive summary designed for the investment committee, plus detailed technical appendices for the operating team.

The identification of $400,000 in annual vendor waste provided an immediate post-acquisition savings opportunity. SBK provided a prioritized contract renegotiation schedule so the PE firm’s operating team could begin capturing these savings on day one after close.

The 23 critical security findings were the most consequential discovery. SBK’s team estimated that full remediation of the security gaps would require approximately $650,000 and 6 months of focused effort. Several findings, particularly those related to HIPAA compliance, carried potential regulatory penalty exposure that significantly impacted the risk profile of the deal.

Based on the totality of findings — security remediation costs, infrastructure migration expenses, technical debt, and vendor waste — the PE firm’s deal team renegotiated the acquisition terms, resulting in a $1.2 million price adjustment. The adjustment reflected both the direct remediation costs and a risk premium for the security and compliance gaps.

Beyond the price impact, SBK’s integration roadmap gave the PE firm a concrete plan for the first 90 days post-acquisition. The operating team knew exactly what to prioritize, what it would cost, and what resources they would need. There were no surprises after close.

The engagement underscored the value of independent, vendor-neutral IT due diligence in M&A transactions. By investing a fraction of the deal value in rigorous technology assessment, the PE firm protected its capital, negotiated from a position of knowledge, and entered the acquisition with a clear-eyed view of the technology they were buying.
