An Overview of Financial Ratios

Introduction

You're sizing up a business and need a clear, fast read on health and value, so financial ratios exist to show profitability, liquidity, solvency, efficiency, and market valuation-each gives a different lens on performance and risk and helps you decide buy, hold, or fix operations; profitability (margins, ROE), liquidity (current ratio), solvency (debt/equity), efficiency (asset turnover), and valuation (P/E, EV/EBITDA) are the core groups. Data comes from the income statement, balance sheet, cash flow statement and live market data; use quarterly (10-Q) and annual (10-K) filings for trends, monthly or weekly cash reports for working-capital moves, and adjust for differing accounting policies so comparisons stay valid-here's quick math: current ratio = current assets ÷ current liabilities; if it's 1.5 the firm covers short-term obligations comfortably, if 0.8 you should probe liquidity further (defintely check cash flow timing).

Key Takeaways

• Use five ratio lenses-profitability, liquidity, solvency, efficiency, valuation-to answer different questions about performance, risk, and value.
• Source ratios from the income statement, balance sheet, cash flow statement and market data (10-Q/10-K preferred); adjust for accounting differences and seasonality for valid comparisons.
• Use benchmarks and covenant metrics (e.g., current ratio ≈1.5 comfortable, <0.8 a red flag; interest coverage and net debt/EBITDA for debt risk) to flag concerns.
• Always analyze trends and peer sets and adjust for one‑offs-never base decisions on a single ratio or period.
• Next step: run a 3‑year trend + peer comparison, then deep‑dive cash flows and any covenant‑relevant ratios flagged.

An Overview of Financial Ratios - Profitability

You're assessing a firm's profit engine to decide if the business makes, keeps, and converts profit into returns-here's the direct takeaway: focus first on margins to see pricing and cost structure, then on returns (ROA, ROE) to see how efficiently the firm uses capital. Keep adjustments for one-offs, tax and interest effects, and asset definitions.

Gross profit margin and operating margin

Gross profit margin (gross margin) measures how much revenue remains after direct costs (cost of goods sold, COGS) - it's a pricing and unit-cost signal. Formula: gross margin = (Revenue - COGS) / Revenue. Quick math example: if Revenue = $1,000,000 and COGS = $600,000, gross margin = 40%. What this hides: mix shifts (higher-margin SKUs), inventory accounting (FIFO/LIFO), and markdowns.

Steps to use gross margin

• Pull revenue and COGS from the income statement
• Calculate margin by period and plot trend over 3 years
• Adjust COGS for major inventory write-downs or one-off freight
• Compare to three peers and industry median

Operating margin connects product economics to the cost base above COGS; formula: operating margin = Operating Income / Revenue. Operating margin shows operating leverage (how fixed costs amplify swings). Example: Operating Income = $150,000 on same revenue → operating margin = 15%. If fixed costs are high, small revenue drops cut operating margin fast.

Best practices

• Decompose operating expenses: fixed vs variable
• Use EBITDA margin for capital-light firms or heavy non-cash charges
• Adjust for non-recurring restructuring or large stock comp
• Benchmark on same accounting (GAAP vs non‑GAAP)

One-liner: Gross margin shows unit economics; operating margin shows how well the company covers its running costs.

Net profit margin and return on assets (ROA)

Net profit margin measures the bottom-line after interest, taxes, and one-offs: net margin = Net Income / Revenue. Example: Net Income = $90,000 on Revenue = $1,000,000 → net margin = 9%. Watch for one-off gains, tax-rate swings, and extraordinary items that distort comparability.

Actionable steps for net margin

• Run GAAP net income and an adjusted net income (remove one-offs)
• Isolate tax rate effects; normalize to a sustainable tax rate
• Check interest expense trends-rising interest lowers net margin
• Compare trailing twelve months (TTM) to fiscal year to smooth seasonality

Return on assets (ROA) measures how efficiently assets generate profit: ROA = Net Income / Average Total Assets. Use average assets (begin+end)/2. Example: Net Income = $90,000, Average Assets = $2,000,000 → ROA = 4.5%. ROA is useful when comparing capital intensity across firms: low ROA in heavy industries is expected.

Considerations and checks

• Prefer operating ROA (Operating Income after-tax / average assets) for operating efficiency
• Adjust assets for operating leases and major intangibles
• Use asset turnover (Revenue / Average Assets) to decompose ROA into margin and turnover
• Watch acquisition effects-book assets jump, ROA temporarily falls

One-liner: Net margin tells you what's left per dollar sold; ROA tells you how well assets convert into that profit.

Return on equity (ROE) and leverage impact

ROE measures shareholder return: ROE = Net Income / Average Shareholders' Equity. Example: Net Income = $90,000, Average Equity = $500,000 → ROE = 18%. High ROE can be great, but it can be driven by financial leverage rather than operational strength.

DuPont decomposition (practical tool)

• ROE = Net margin × Asset turnover × Equity multiplier
• Net margin = Net Income / Revenue
• Asset turnover = Revenue / Average Assets
• Equity multiplier = Average Assets / Average Equity

Example DuPont walk: Net margin 9% × Asset turnover 0.5x × Equity multiplier 4x = ROE 18%. That shows whether ROE comes from margin, efficiency, or leverage.

Practical steps and red flags

• Compute ROE and run DuPont to find the driver
• Check trend in equity (share buybacks reduce equity and boost ROE)
• Watch rising equity multiplier-means more leverage and higher risk
• Cross-check ROE against ROA; wide gap indicates leverage impact

One-liner: ROE measures shareholder returns; use DuPont to see if it's real or just leverage-driven - defintely dig deeper if leverage is rising.

Liquidity ratios

You need to know whether the business can pay bills in the next 12 months - these ratios show short-term coverage, how quickly assets convert to cash, and whether cash flows back up the bookkeeping. Here's the quick takeaway: track the current, quick, and cash ratios monthly and stress-test with a 13-week cash forecast.

Current ratio - short-term coverage and typical benchmarks

The current ratio = current assets / current liabilities; it measures whether near-term assets cover near-term liabilities. A common benchmark is around 1.5-3.0 for stable, non-financial companies; lower in asset-light businesses, higher in highly seasonal or inventory-heavy firms.

Step-by-step calculation and checks:

• Pull current assets and current liabilities from the FY2025 balance sheet (use year-end and TTM averages).
• Compute: Current ratio = Current assets ÷ Current liabilities.
• Adjust for one-offs: subtract classified receivables that are disputed or include customer deposits in liabilities.

Example (FY2025): Current assets $450,000,000, current liabilities $300,000,000 → current ratio = 1.50. Here's the quick math: 450 ÷ 300 = 1.5. What this hides: year-end spikes in payables or inventory can distort the snapshot.

Best practices: trend the ratio quarterly for 3 years, compare to 3 peers, and test scenarios where receivables slow 30% - if the ratio falls below 1.0, flag liquidity risk. One-liner: aim for a ratio comfortably above 1 so short-term obligations aren't at risk.

Quick ratio (acid test) - excludes inventories for near-cash view

The quick ratio = (cash + short-term investments + accounts receivable) / current liabilities; it removes inventory to show near-cash coverage. Rule of thumb: target at least 1.0 in businesses with unpredictable inventory turns; lower is acceptable in fast-turn retail but verify.

Steps and adjustments:

• Use FY2025 TTM cash, ST investments, and net receivables (after allowances).
• Exclude slow-moving inventory and receivables older than 90 days unless contractually collectible.
• Recompute under stress: delay collections by 30-60 days, or write down 10-20% of AR for high credit-risk customers.

Example (FY2025): cash + ST investments + AR = $280,000,000; current liabilities = $300,000,000 → quick ratio = 0.93. Quick math: 280 ÷ 300 = 0.933. What to watch: receivables quality - a high quick ratio with concentrated AR is risky.

Best practices: build an AR aging roll-forward, verify collectability with sales contracts, and use the quick ratio as a red flag, not a sole decision rule. One-liner: the acid test shows how near-term obligations fare without relying on inventory.

Cash ratio and operating cash flow coverage - conservative cash-only coverage

The cash ratio = (cash + short-term investments) / current liabilities; it is the most conservative liquidity view. Typical mid-market firms run cash ratios between 0.2-0.5; a 1.0 cash ratio means you could pay all current liabilities with cash on hand.

Operating cash flow coverage measures real cash ability to meet obligations: OCF coverage = operating cash flow (from the cash flow statement, TTM) ÷ current liabilities (or short-term debt). Use TTM cash from ops to smooth seasonality.

Steps, checks, and examples:

• From FY2025 cash flow: use TTM operating cash flow and year-end cash and ST investments.
• Compute cash ratio and OCF coverage; run monthly 13-week cash forecasts to validate.
• Stress-test: model AR collection lag +20 days and inventory build +15% for 3 months, then recompute ratios.

Example (FY2025): cash + ST investments = $90,000,000; current liabilities = $300,000,000 → cash ratio = 0.30. Operating cash flow (TTM FY2025) = $150,000,000 → OCF coverage = 0.50 (150 ÷ 300). Quick math: 90 ÷ 300 = 0.3; 150 ÷ 300 = 0.5. What this hides: OCF can be lumpy-capital cycle or one-time working capital releases can inflate the TTM number.

Best practices: reconcile cash ratio to bank balances, exclude restricted cash, and map OCF to scheduled debt maturities and covenants. If OCF coverage < 1.0, plan actions: tighten collections, extend payables, or secure a committed line. One-liner: cash is king - but cash flow pays the bills over time, so measure both.

Immediate next step: Finance - run a monthly liquidity pack using FY2025 TTM data and a 13-week cash forecast by Friday; include scenario where AR collections slow by 30% (owner: Finance Director).

Solvency and leverage ratios

You're checking whether a company can survive a downturn or take on more debt; here's the quick takeaway: focus on capital-structure ratios for long-term risk, interest cover for near-term cash stress, and net-debt/EBITDA for covenant and refinancing risk.

Debt-to-equity and debt-to-capital and debt-to-assets

If you want to know how a firm funds itself and how much financial risk shareholders carry, start here. Debt-to-equity = total debt / shareholders equity. Debt-to-capital = total debt / (total debt + equity). Debt-to-assets = total debt / total assets. Use the book values from the FY2025 balance sheet, but also check market equity where relevant.

Example (FY2025): total debt $1,200m, equity $800m, assets $3,000m → debt-to-equity = 1.5x, debt-to-capital = 60%, debt-to-assets = 40%.

Here's the quick math: higher ratios = more creditor risk and higher return volatility for equity holders. What this estimate hides: off-balance-sheet leases, pension deficits, or contingent liabilities can raise effective leverage.

Steps to use these ratios:

• Pull FY2025 total debt (short + long-term) and shareholders equity.
• Adjust debt for finance leases and pension deficits.
• Compare book-equity ratio to market-cap (market leverage) for takeover/refinancing risk.
• Benchmark against direct peers and industry medians (same fiscal year).

Best practices and considerations:

• Flag debt-to-capital > 50% as higher risk in many industries.
• Use net-debt versions when cash is material.
• Note cyclical industries tolerate higher leverage at peak earnings, not troughs.
• When in doubt, stress-test with a 20-40% drop in equity value.

One line: treat these ratios as a structural read-don't ignore off-balance items, they can quickly flip the picture.

Interest coverage ratio (EBIT / interest)

This ratio shows how many times operating profit (EBIT) covers interest expense - a direct read on the company's ability to service debt from core earnings. Use FY2025 EBIT and interest expense from the income statement or TTM (trailing 12 months) if FY numbers lag.

Example (FY2025): EBIT $300m, interest expense $50m → interest coverage = 6.0x. Generally, coverage < 3x raises questions; <1x signals likely distress.

Steps and checks:

• Decide metric: EBIT (earnings before interest & taxes) for operating read; EBITDA sometimes used by lenders.
• Use TTM if interim results available; compare FY2025 and TTM to spot seasonality.
• Adjust EBIT for recurring non-cash items and add-backs lenders accept (e.g., normalized restructuring).
• Recalculate with forward estimates for covenant testing before refinancing.

Best practices:

• Confirm whether covenants use EBIT or EBITDA and whether they allow add-backs.
• Watch short-term rises in interest (rate resets) - a +200 bps move can halve coverage quickly.
• If coverage nears 2-3x, model a downside case: 20% EBIT drop or 25% higher interest cost.

One line: interest coverage is your early-warning gauge - when it drifts below 3x, tighten monitoring and run liquidity scenarios.

Net debt / EBITDA

Net debt/EBITDA measures leverage using cash-adjusted debt and operating cash proxy (EBITDA). Lenders and rating agencies use it for covenants and credit grades. Net debt = total debt - cash & cash equivalents (FY2025 values). EBITDA should be consistent (TTM or FY2025); be clear which you use.

Example (FY2025): total debt $1,200m, cash $200m → net debt $1,000m. EBITDA $350m → net debt/EBITDA = 2.86x. Common covenant buckets: <3.0x (investment grade/comfortable), 3-4.5x (levered but typical for buyouts), > 4.5x (higher risk / refinancing watch).

Steps to apply:

• Compute net debt with FY2025 cash; include lease liabilities if covenants specify (IFRS 16 impact).
• Use consistent EBITDA (TTM vs FY) and remove one-offs if the covenant allows.
• Map to covenant definitions: some use pro forma or adjusted EBITDA (add-backs for synergies, cost saves).
• Run sensitivity: 10-30% EBITDA decline and 10% cash draw to see covenant breach risk.

Best practices and covenant hygiene:

• Confirm whether the covenant uses net leverage or gross leverage.
• Model both reported and covenant-adjusted EBITDA; lenders often accept add-backs that management wouldn't.
• Build covenant triggers into refinancing plans - if you're at 3.5x, plan a 12-18 month buffer.
• Flag maturing debt within 12-24 months; high net leverage plus upcoming maturities is a red alert.

One line: net debt/EBITDA is covenant-critical - if it's approaching lender caps, you must model covenant cures and a refinancing timeline or equity options.

Efficiency and activity ratios

You're trying to free cash from working capital and spot operational bottlenecks so you can fund growth or cut risk - this section shows the key ratios, exact formulas, quick math, and concrete next moves.

Inventory and stock

What it measures: how fast inventory converts to sales; higher turnover usually means lower working-capital needs but risks stockouts.

Formulas: Inventory turnover = COGS / Average inventory. Days inventory outstanding (DIO) = 365 / Inventory turnover.

Here's the quick math using a clear example: if COGS = $2,400,000 and average inventory = $400,000, then inventory turnover = 6 and DIO = 60.8 days. What this estimate hides: seasonality and obsolete slow-moving stock can inflate average inventory and understate turnover.

Practical steps

• Track SKU-level turnover weekly
• Segment inventory: high-turn, medium, slow
• Reduce safety stock for high-turn SKUs
• Use ABC or Pareto analysis quarterly
• Run a dead-stock clean-up every 6-12 months

Benchmarks and judgement

• Retail: 6-12 turns typical
• Manufacturing: 2-6 turns typical
• Perishables: much higher; heavy CAPEX industries lower

Actionable tactics

• Negotiate vendor-managed inventory
• Implement just-in-time for top 20% SKUs
• Slow-movers: discount or write-down within 90 days

One-liner: Push turns up, DIO down, but don't break service levels - monitor fill rate.

Receivables and payables

What they measure: collection effectiveness and supplier financing; they directly change operating cash flow.

Formulas: Receivables turnover = Net credit sales / Average receivables. DSO = 365 / Receivables turnover. Payables turnover = Purchases / Average payables. DPO = 365 / Payables turnover.

Example math: Revenue (net credit) = $5,000,000, average AR = $500,000 → AR turnover = 10, DSO = 36.5 days. Purchases = $3,000,000, average AP = $300,000 → AP turnover = 10, DPO = 36.5 days. Watch out: changes in credit policy or one-time sales cause big swings.

Practical steps to improve DSO

• Shorten terms for new accounts to net 30
• Automate invoicing and e-delivery
• Offer discounts for early pay (2/10 net 30) selectively
• Use collections scorecards and age-bucket aging
• Consider factoring for select receivables

Practical steps to optimize DPO

• Consolidate suppliers to get longer terms
• Use dynamic discounting if cash-rich
• Schedule payments to maximize float but avoid straining supplier relations
• Track supplier KPIs to avoid supply disruption

Benchmarks and caveats

• Healthy DSO often 30-60 days depending on industry
• Extending DPO improves cash but can damage supplier terms
• High DSO with rising sales signals collection deterioration

One-liner: Cut DSO faster than you cut DPO - suppliers notice and so does revenue continuity.

Asset efficiency and working-capital turnover

What they measure: Asset turnover = Revenue / Average total assets; working-capital turnover = Revenue / Average working capital. They show how much revenue each dollar of asset or working capital produces.

Example math: Revenue = $10,000,000, avg assets = $5,000,000 → Asset turnover = 2.0. Revenue = $10,000,000, avg working capital = $500,000 → WC turnover = 20. Higher is usually better, but capital-intensive industries will always look low.

Steps to analyze meaningfully

• Always compare to industry peers and company history
• Normalize assets for leases and one-off impairments
• Break down by business unit for multi-line firms
• Monitor CapEx vs. efficiency: new assets can temporarily lower turnover

Cash conversion cycle (CCC) implications

• CCC = DIO + DSO - DPO
• Shorten CCC to free cash
• Target projects with quick payback that improve turns

Concrete actions to raise turnover and shorten CCC

• Reengineer processes to reduce manual order-to-cash steps
• Use inventory forecasting tied to demand signals
• Lease vs buy: assess impact on asset base
• Implement rolling 13-week cash forecast

One-liner: Improve turnover by fixing the slowest link in CCC - that's where dollars unlock fastest.

Valuation and market ratios

You're trying to judge whether a market price is cheap, fair, or expensive versus what the books and cash flows show - the short answer: use P/E and EV/EBITDA as your primary market multiples, supplement with P/B and dividend metrics for asset-heavy or income-focused names, and always reconcile multiples to forward cash-flow and analyst estimates.

Here's the quick math approach you should use: get trailing and forward per-share earnings and EBITDA for fiscal year 2025, compute market-implied values, then stress-test for growth and margin scenarios. What this estimate hides: accounting quirks, one-offs, and capital-structure differences that can move the multiple a lot.

Price multiples and enterprise valuation

Price-to-earnings (P/E) and enterprise value / EBITDA (EV/EBITDA) are your go-to market multiples - P/E ties market price to per-share earnings and shows how much investors pay for current profitability; EV/EBITDA is capital-structure-neutral and better for cross-capitalization comparison.

Practical steps to compute and use them:

• Calculate trailing P/E = share price / trailing EPS (FY2025). Example: if price = $42.00 and EPS FY2025 = $3.50, trailing P/E = 12.0x.
• Compute forward P/E = price / consensus FY2026 EPS. Use sell-side median; adjust for one-offs.
• Build EV for FY2025: market cap + net debt. Example: shares outstanding = 100 million → market cap = $4.20 billion; net debt = $800 million; EV = $5.00 billion.
• Compute EV/EBITDA: EV / FY2025 EBITDA. Example: EBITDA = $650 million → EV/EBITDA = 7.7x.
• Adjust EBITDA for one-offs, operating leases (capitalize or add back), and non-cash pension items before comparing peers.

Best practices and checks:

• Prefer forward multiples for valuation decisions; trailing for performance checks.
• Compare to industry median and 25th/75th percentiles, not just a single peer.
• Run sensitivity: P/E or EV/EBITDA ±10% vs EPS/EBITDA growth ±200 bps.
• Watch EPS sensitivity: a 10% EPS miss raises trailing P/E by ~1.1x in the example above.

One-liner: Use P/E to read market expectations and EV/EBITDA to neutralize capital structure when comparing peers.

Balance-sheet signals and shareholder returns

Price-to-book (P/B), dividend yield, and payout ratio tell you whether the market values a firm above or below its net assets and whether current income is sustainable.

Practical steps with FY2025 numbers:

• Compute book value per share (BVPS) = shareholders equity / shares outstanding. Example: equity = $2.10 billion, shares = 100 million → BVPS = $21.00.
• P/B = price / BVPS. Example: price = $42.00 → P/B = 2.0x. P/B matters most for banks, insurers, and asset-heavy industrials.
• Dividend yield = annual dividend per share / price. Example: dividend per share = $1.68 → yield = 4.0%.
• Payout ratio = dividend per share / EPS. Example: $1.68 / $3.50 = 48%. Check free-cash-flow (FCF) coverage: if FCF FY2025 = $400 million, FCF yield = 9.5% and FCF coverage = FCF / total dividends = ~1.0x (compute dividend bill = $1.68 100m = $168 million).

Best practices and cautions:

• Adjust book value for intangible write-ups, deferred tax assets, and goodwill impairments before trusting P/B.
• Use FCF coverage, not only net income, to test dividend sustainability; defintely stress-test under capex and working-capital pulls.
• When payout > 70%, treat as return-of-capital unless FCF supports it.
• For buyback-heavy firms, convert buybacks to a synthetic dividend to measure total shareholder payout.

One-liner: Treat P/B as an asset sanity check and dividend metrics as evidence of payout sustainability - always cross-check with FCF.

Reconciling accounting ratios and market expectations

Accounting ratios lag; markets price forward expectations. Reconciliation means converting accounting flows into market-implied growth and testing whether that growth is realistic.

Concrete steps to reconcile FY2025 accounting to market multiples:

• Derive market-implied EPS growth from P/E using a simplified PEG logic: implied growth ≈ P/E / target PEG. Or invert: implied EPS = price / P/E. Example: price $42.00 and P/E 12.0x → market-implied EPS = $3.50 (same as reported). Change EPS by ±10% and reprice to see upside/downside.
• Convert consensus forward EPS and EBITDA into forward multiples and compare to current market multiples; if forward EV/EBITDA drops materially, the market expects margin expansion or multiple expansion.
• Adjust accounting metrics: remove one-offs, normalize tax rates, capitalize R&D or operating leases if peers do so; reconcile differences in share count (options, RSUs) to per-share metrics.
• Run three scenarios: downside (earnings -15%), base (consensus), upside (earnings +15%); compute resulting P/E and EV/EBITDA and show implied returns.

Practical reconciliation example (quick math):

If FY2025 EPS = $3.50 and you expect FY2027 EPS = $4.55 (growth CAGR ~12%), a current P/E of 12.0x implies a PEG ~1.0x - reasonable for steady-growth firms but expensive for cyclical ones. Always map implied growth back to realistic ROIC (return on invested capital) and reinvestment rates.

Final checks and sources to fetch now: pull FY2025 consensus EPS and EBITDA from your data vendor (Bloomberg/Refinitiv/FactSet), download FY2025 financials, and align definitions of EBITDA and net debt across peers before trusting multiples.

One-liner: Convert market prices into implied earnings and cash-flow paths, then stress-test against realistic ROIC and reinvestment assumptions.

Next step: Finance - run a 3-year FY2023-FY2025 trend and peer set for the target firm, produce trailing and forward P/E and EV/EBITDA comps, and deliver a 3-scenario valuation sheet by Friday, December 12, 2025.

Practical checklist, pitfalls, and next steps

Practical checklist: trend analysis, peer comparison, adjust for one-offs

You're wrapping up ratio work and need a tight checklist so ratios lead to decisions, not noise.

One line: Build a standard 3-year view (FY2023-FY2025) plus trailing twelve months (TTM) and compare to a matched peer set.

Steps to run now:

• Collect financials: income statement, balance sheet, cash flow for FY2023, FY2024, FY2025 and TTM.
• Calculate core ratios: margins, ROA, ROE, current/quick/cash ratios, debt ratios, interest coverage, net debt / EBITDA, inventory/receivable/payable turns, asset turnover, P/E, EV/EBITDA, P/B, dividend yield.
• Normalize results: remove one-offs (restructuring, asset sales), adjust tax/interest timing, and restate prior years where needed.
• Create benchmarks: use peers with ±50% revenue and same end-of-year fiscal month; capture median and quartiles.
• Flag material moves: margin change > 200 basis points, ROE swing > 5 percentage points, interest coverage drop below 3.0x, net debt/EBITDA above 3.5x.

Here's the quick math: if gross margin falls from 40% to 34%, that's a 600 basis point compression - immediate cause analysis required.

What this estimate hides: industry cycles and FX effects can mimic permanent deterioration; always separate operational vs. macro drivers.

Common pitfalls: mixing fiscal periods, ignoring seasonality, overrelying on one ratio can be defintely misleading

You're comparing numbers across firms or years and might be led astray by timing or accounting differences.

One line: Check fiscal year-ends, seasonality, accounting policies, and non-GAAP adjustments before comparing ratios.

Frequent mistakes and practical fixes:

• Mixing fiscal periods - align to common 12-month windows or use TTM.
• Ignoring seasonality - compare same-quarter patterns (retail Q4 vs Q1 matters).
• Overrelying on one ratio - use a small dashboard (liquidity, solvency, profitability, efficiency, valuation).
• Neglecting accounting changes - restate for lease accounting (ASC 842/IFRS 16), pension measurement shifts, or M&A accounting.
• Confusing operational vs one-off items - treat items > 5% of operating profit as potentially distortive and disclose adjustments.
• Using GAAP EBITDA vs adjusted EBITDA inconsistently - document add-backs and keep a reconciliation.

Concrete example: a supplier offers extended payment terms; DPO rises 20 days. That can improve cash flow short-term but hide supplier stress - call it out.

Next step: run a 3-year trend and peer set for target firm; flag ratios needing deeper cash-flow or covenant review

You want a clear deliverable that turns ratios into action items for finance and the business.

One line: Finance builds the 3-year+TTM model, identifies 3-5 risky ratios, and hands off issues for cash-flow or covenant deep-dive.

Immediate action plan (owner: Finance):

• Pull FY2023-FY2025 and TTM data from the ERP/EDGAR/CapIQ sources by December 12, 2025.
• Compute standard ratio set and peer medians; store in a single worksheet with formulas visible.
• Apply flags: interest coverage <3.0x, net debt/EBITDA > 3.5x, current ratio < 1.0, negative operating cash flow for two consecutive years, DSO > peer median + 30 days.
• For each flag, require a one-paragraph explanation and recommended next step (e.g., covenant talk, refinancing, working-capital program).
• Deliverables: ratio workbook, peer comparison chart, and a queue of up to 5 items needing deeper cash-flow or covenant review - due on the date above.

Owner: Finance - draft the 3-year ratios, highlight covenant risks, and schedule a 45-minute review with Treasury and Legal by the delivery date.
