Cash Flow in Financial Due Diligence

Cash Flow in Financial Due Diligence

Cash flow is the lifeline of any business, especially during acquisitions. It reveals how money moves in and out of a company, helping buyers assess financial health, avoid overpaying, and spot risks. For small and medium businesses (SMBs), where financial reporting can be inconsistent, analyzing cash flow ensures smarter decisions.

Key takeaways:

  • Cash flow analysis focuses on liquidity, operational expenses, and growth potential.
  • Metrics like Operating Cash Flow (OCF), Free Cash Flow (FCF), and Net Working Capital (NWC) provide insights into a business's ability to sustain itself.
  • Tools like Quality of Earnings (QoE) and scenario-based testing help uncover risks like declining cash flow, non-recurring items, or revenue recognition issues.
  • Modern platforms like Kumo streamline deal sourcing and cash flow analysis using AI, making the process faster and more precise.

Bottom line: Understanding cash flow is essential for verifying numbers, identifying risks, and ensuring post-acquisition success. Without it, 82% of businesses fail due to cash flow problems.

Key Cash Flow Metrics and What They Mean

Understanding key cash flow metrics is essential for evaluating a company's financial health during due diligence. These metrics provide valuable insights into how a business generates, manages, and utilizes cash. Here are some of the most important ones every SMB buyer should know.

Operating Cash Flow and Free Cash Flow

Operating Cash Flow (OCF) represents the cash generated through a company's regular business operations. It starts with net income, adds back non-cash expenses like depreciation and amortization, and adjusts for changes in working capital. This metric helps determine if the business can sustain its day-to-day operations without needing external funding.

Free Cash Flow (FCF), on the other hand, reflects the cash available for investments, debt repayment, or distributions after accounting for capital expenditures. You calculate FCF by subtracting capital expenses from operating cash flow, providing a clear picture of the cash left for growth or other financial commitments.

EBITDA and Adjusted EBITDA

EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) is a popular measure used to gauge a company's operating performance and profitability. By excluding factors like financing costs and tax variations, it offers a standardized look at the business's core operations. However, it doesn't account for capital expenditures or changes in working capital, which can limit its usefulness in some cases.

Adjusted EBITDA refines standard EBITDA by removing one-time expenses, non-recurring items, and owner-specific costs unlikely to continue under new ownership. For example, this could involve excluding above-market owner salaries or one-time legal fees. For SMB buyers, it's often helpful to consider multiple metrics - like Seller’s Discretionary Earnings (SDE), adjusted EBITDA, and free cash flow - to get a more complete financial picture.

Net Working Capital

Net Working Capital (NWC) measures a company's short-term financial health by subtracting current liabilities from current assets. It serves as an indicator of liquidity and the ability to meet short-term obligations. In mergers and acquisitions, NWC calculations often exclude items like cash and short-term debt to focus on operational liquidity.

Current Assets Included Excluded
Accounts receivable, Inventory, Petty cash, Prepaid expenses Cash and cash equivalents, Marketable securities
Current Liabilities Included Excluded
Accounts payable, Accrued expenses, Customer deposits, Deferred revenue Related-party items, Short-term debt, Lines of credit, Taxes payable

NWC can directly impact the purchase price in a transaction. For instance, if Company A agrees to acquire Company B for $100 million with a target NWC of $10 million, but the actual NWC at closing is $12 million, the purchase price may rise by $2 million.

Buyers use NWC analysis to assess whether the business can sustain its operations without requiring unexpected cash injections. A working capital ratio above 1 indicates the company can cover its current liabilities, while a ratio between 1.5 and 2.5 is often considered healthy. Monitoring NWC on the cash flow statement is equally important - an increase in NWC ties up cash, while a decrease releases cash for other needs. Properly calculated post-close adjustments ensure fairness for both buyer and seller.

Grasping these metrics is a critical step in evaluating the cash flow and financial health of a potential acquisition. They provide a strong foundation for deeper analysis, setting the stage for more detailed financial evaluations in the next section.

Methods for Analyzing Cash Flow

Using analytical methods can uncover risks and opportunities that might not be visible in basic financial reports.

Quality of Earnings (QoE) Analysis

A Quality of Earnings (QoE) analysis builds upon standard cash flow metrics to provide a deeper understanding of a company's financial health. This third-party review goes beyond surface numbers to ensure that reported earnings accurately represent the company’s operational performance.

QoE analysis validates EBITDA by thoroughly reviewing financial statements, while the proof of cash component ensures that actual cash flow matches recorded revenues and expenses. Adjustments are typically categorized into three groups: due diligence adjustments (normalizing expenses and revenue recognition), management-proposed adjustments (extraordinary items), and proforma adjustments (retrospective changes).

Additionally, this analysis examines revenue streams for concentration risks and evaluates whether accounting practices might inflate the company’s financial position. For small and medium-sized business (SMB) acquisitions, this process is especially important, as it helps differentiate between ongoing, sustainable cash-generating activities and one-time events that are unlikely to recur under new ownership.

Scenario-Based Cash Flow Testing

Scenario modeling provides insights into how cash flow might respond to different conditions, helping identify potential financial vulnerabilities. This approach typically involves creating best-case, worst-case, and most-likely scenarios.

The process starts by developing a baseline forecast using historical cash flow data. Key variables that significantly influence cash flow - such as sales volume, payment terms, operating costs, and market conditions - are then analyzed. For instance, a 13-week cash flow forecast might reveal that in a worst-case scenario, expenses could outpace inflows by week 8, leading to a cash shortfall. On the other hand, a best-case scenario might show surplus cash during weeks 6 to 10, which could be used for marketing or purchasing new equipment.

Scenario testing is particularly valuable for SMB acquisitions, as smaller businesses often lack the financial reserves to handle unexpected challenges. By identifying potential cash flow issues early, you can plan specific strategies to address them and ensure the business remains stable.

This type of modeling also ties back to historical reviews, helping to contextualize current cash flow trends.

Historical Trend Analysis

Examining historical cash flow trends offers critical context for assessing a company’s financial stability and future potential. Unlike single-period snapshots, this method reveals patterns that highlight long-term strengths or emerging challenges.

Historical trend analysis employs three main techniques. Horizontal analysis measures changes in line items over time, expressed as percentages or absolute shifts, which can help pinpoint cyclical peaks or identify whether margin compression results from internal inefficiencies or external pressures. Vertical analysis converts each line item into a percentage of a base figure, showing how different components contribute to overall cash flow. Ratio analysis evaluates relationships between financial statement items to track broader financial health trends.

This analysis helps uncover trends that affect cash flow sustainability. For example:

  • Upward trends may indicate growing demand and strong market positioning.
  • Downward trends could signal underlying issues that need addressing.
  • Seasonal trends highlight predictable fluctuations, which are especially relevant for businesses with cyclical cash flow patterns.

For SMB acquisitions, comparing the target company’s cash flow trends to industry averages can provide valuable insights into its relative performance. This comparison helps determine whether observed trends are specific to the company or reflect broader industry dynamics. Given that 30% of business failures are attributed to running out of cash, understanding these patterns is essential for predicting future cash flow stability.

Cash Flow Red Flags and Risk Factors

Spotting warning signs during a cash flow analysis can play a key role in determining the success of an acquisition. While these red flags don’t necessarily mean a deal is off the table, they do call for closer scrutiny. They might even lead to renegotiating the price or adjusting deal terms. Here’s a closer look at some common red flags that deserve attention and further investigation.

Inconsistent or Declining Operating Cash Flows

Erratic or steadily declining operating cash flows often signal deeper issues within a business. When cash flow patterns fluctuate significantly or show a consistent downward trend, it’s usually a sign of operational inefficiencies or other underlying problems. These issues can disrupt operations and increase financial risk.

The numbers highlight how critical sound cash flow management is: 82% of small businesses fail due to cash flow problems. A 2019 survey by Intuit QuickBooks revealed that 61% of small business owners faced cash flow challenges, and 44% of failed startups cited "running out of cash" as the main reason for closing.

"The moral of the story...review the numbers, respect the numbers, but don't use the numbers as an excuse to ignore the underlying business reality and conditions within which the numbers exist."
– John Tate, Cincinnati-based CFO

Acquirers with limited free cash flow often target lower-quality companies, which can lead to poor stock market performance post-acquisition. If inconsistent cash flows surface during due diligence, it’s crucial to determine whether they stem from predictable seasonal patterns or more serious operational challenges. Pinpointing these trends early can help refine acquisition strategies and valuations.

Impact of Non-Recurring Items

Non-recurring items can temporarily inflate financial metrics, creating a misleading snapshot of a company’s performance. These one-time gains or losses don’t stem from regular operations and are unlikely to repeat after the acquisition, making them risky when evaluating financial health.

"Non-Recurring Items are gains and losses recognized on the income statement that must be adjusted, as they are neither part of ongoing core operations nor an accurate reflection of future performance."
Wall Street Prep

Common examples of non-recurring items include:

  • Restructuring Expenses: Costs like advisory fees or consultant charges that won’t persist after the deal closes.
  • Litigation Settlements: Legal costs or gains from lawsuits, which are not part of normal operations.
  • Asset Impairments: Write-downs of inventory or equipment that don’t reflect ongoing performance.
  • Asset Sales: Temporary cash boosts from selling non-core assets, not indicative of sustainable earnings.
  • Severance Packages: One-time costs tied to employee terminations during downsizing efforts.

Adjusting for these items - often referred to as "scrubbing" the financials - provides a clearer view of what cash flows might look like under normal conditions. Look for terms like "non-recurring", "infrequent", "unusual", or "extraordinary" in the income statement, MD&A, and footnotes when reviewing financials.

Beyond these adjustments, how a company recognizes revenue can also reveal hidden cash flow issues.

Revenue Recognition Issues

Improper revenue recognition can create a gap between reported revenues and actual cash collections, leading to inflated cash flow projections. This is a frequent issue in small and medium-sized business (SMB) acquisitions, where accounting standards may be inconsistently applied. Sellers might unintentionally - or intentionally - present a skewed financial picture.

For instance, aggressive revenue recognition practices, such as recording sales before they’re earned or collected, can make current performance look better than it actually is. This disconnect becomes especially concerning when companies prioritize revenue figures over actual cash collections.

To spot potential revenue recognition problems, examine the relationship between reported revenues and accounts receivable. Aging accounts receivable can suggest collection issues tied to premature revenue recognition. Similarly, unusual trends in accounts receivable compared to reported revenues warrant further investigation. A collaborative review involving finance, sales, and operations teams can also help ensure revenue recognition practices align with actual cash flows.

While revenue recognition issues may not necessarily derail a deal, they often justify valuation adjustments and the inclusion of contractual protections. Tools like earnout provisions, specific warranties, and escrow arrangements can safeguard against surprises after the deal closes. As Alex Silensky, Partner at OGS Capital, puts it:

"Ultimately, all red flags [are] just a question of proper communication with the seller."

Using Technology for Better Cash Flow Analysis

Modern platforms are transforming how cash flow analysis is approached, especially during financial due diligence. Automation is taking over much of the manual work, paving the way for AI tools to improve deal sourcing and forecasting.

According to McKinsey, by 2030, 70% of organizations are expected to adopt AI, potentially increasing free cash flow by an impressive 122%. On the flip side, companies without an AI strategy could face a 23% drop in free cash flow.

Conclusion and Key Takeaways

The Importance of Cash Flow in Financial Due Diligence

Cash flow analysis plays a central role in assessing the financial health of small and medium-sized businesses (SMBs) during acquisitions. It offers a real-time perspective on how a company generates and manages its cash, going beyond traditional metrics like credit scores, which often only reflect past performance. This dynamic view provides valuable insights into a business's liquidity, operational efficiency, and ability to handle post-acquisition demands.

Research consistently highlights cash flow issues as one of the primary reasons businesses fail. Understanding this makes cash flow analysis an essential tool for safeguarding investments. By examining liquidity, operational efficiency, and financial flexibility, cash flow analysis can reveal whether a business is equipped to meet debt obligations, fund capital expenditures, and maintain daily operations. It also helps identify potential red flags, such as overdue invoices - an issue affecting about 24% of revenue for the average U.S. business. These insights are crucial during valuation and post-acquisition planning.

Practical Tips for Financial Professionals

To get the most out of cash flow analysis during due diligence, consider these strategies:

  • Adopt a structured framework: Focus on key metrics like operating cash flow ratios, cash flow margins, and cash conversion cycles. These benchmarks help evaluate performance relative to industry standards and ensure the analysis remains relevant as business conditions evolve.
  • Leverage technology: Tools like Kumo simplify deal sourcing and enhance cash flow analysis by consolidating business listings and enabling deeper financial assessments.
