The Financial Rating evaluates six fundamental factors — discounted cash flow (DCF) valuation, return on equity (ROE), return on assets (ROA), debt-to-equity leverage (D/E), and relative price-to-earnings (P/E) and price-to-book (P/B) multiples — each scored 1–5. 2428.TW receives an overall rating of B+. Strongest factors: ROE (4/5), ROA (4/5). Areas of concern: D/E (2/5).

The InsiderStreet Scorecard rates companies across eight dimensions: Profitability (margins, ROA, ROE), Balance Sheet (leverage, liquidity, coverage), Earnings Quality (accruals, cash conversion), Growth (revenue and earnings trajectory), Value (P/E, P/B, earnings yield, Graham criteria), Momentum (revenue and earnings acceleration), Safety (Altman Z-Score risk adjustment), and Cash Flow (operating cash flow quality, FCF conversion, cash coverage). The overall score blends 35% quality, 35% value, and 30% momentum, with a penalty for distress-zone Altman scores. 2428.TW scores highest in Safety (100/100) and lowest in Cash Flow (37/100). A grade of B indicates above-average fundamentals with room for improvement in select areas.

The Altman Z-Score (1968) combines five ratios — working capital, retained earnings, EBIT, market value of equity, and sales, all relative to total assets or liabilities — into a single bankruptcy predictor. 2428.TW scores 5.56, placing it in the Safe Zone (safe > 2.99, distress < 1.81). Bankruptcy is statistically unlikely within the next two years. The Piotroski F-Score (2000) is a 9-point binary checklist — four profitability tests (positive ROA, positive cash flow, improving ROA, cash flow exceeding net income), three leverage tests (declining debt ratio, improving current ratio, no share dilution), and two efficiency tests (improving gross margin, improving asset turnover). Each pass scores 1 point. 2428.TW scores 3/9, suggesting weak financial fundamentals — the company fails the majority of these accounting tests. The Beneish M-Score (1999) is an 8-variable model that detects earnings manipulation by comparing year-over-year changes in receivables, gross margins, asset quality, sales growth, depreciation, SG&A, leverage, and accruals. Scores above −1.78 statistically resemble past manipulators. 2428.TW's score of -2.07 falls below this threshold, suggesting earnings are unlikely to be manipulated. The Ohlson O-Score (1980) is a 9-variable logistic regression that estimates bankruptcy probability using firm size, leverage, working capital, current ratio, profitability (ROA), cash flow coverage, negative equity flag, consecutive losses flag, and earnings trajectory. The raw score is converted to a probability via logistic transformation. 2428.TW's implied 0.0% bankruptcy probability is well within safe territory. Our Credit Rating model scores companies on five weighted components — solvency (30%), earning power (25%), leverage (20%), liquidity (15%), and cash flow quality (10%) — then blends the absolute score with sector and industry peer rankings. For companies with large buyback programs, equity is adjusted by adding back cumulative 5-year repurchases (capped at 80% of FCF generated) to avoid penalizing shareholder-friendly capital allocation. 2428.TW receives an estimated rating of AAA (score: 99.0/100), with a improving trend. The Earnings Quality score measures how well reported earnings are backed by real cash. It evaluates the operating cash flow to net income ratio (OCF/NI ≥ 1.0 means every dollar of earnings is cash-backed) and the accruals ratio (the gap between earnings and cash flow relative to assets — lower is better). 2428.TW's score of 50/100 is moderate — some divergence between reported earnings and underlying cash flows.

Graham Number

$170.67

Equity-based multiples (P/E, P/B, P/FCF) compare the stock price to per-share fundamentals and are affected by capital structure. Enterprise value multiples (EV/EBITDA, EV/Revenue, EV/FCF) strip out debt and cash, making them more useful for cross-company comparisons regardless of how companies are financed. The Graham Number — √(22.5 × EPS × Book Value) — is Benjamin Graham's formula for the maximum price a defensive investor should pay. At 18.7x earnings, 2428.TW trades at a reasonable valuation. Graham's intrinsic value formula yields $170.67 per share, 54% below the current price.

DuPont Decomposition (5-Factor)

The 5-factor DuPont framework breaks Return on Equity into its component drivers — tax efficiency, interest burden, operating profitability, asset utilization, and financial leverage — to reveal what truly drives shareholder returns.

Tax Burden

0.716

NI / EBT

Interest Burden

1.188

EBIT Margin

0.240

EBIT / Rev

Asset Turnover

0.525

Rev / Assets

Equity Multiplier

1.569

Assets / Equity

ROE

16.8%

The 5-factor DuPont identity decomposes ROE as: Tax Burden × Interest Burden × EBIT Margin × Asset Turnover × Equity Multiplier = ROE. This reveals whether returns are driven by operating performance, financial leverage, or tax efficiency — three very different sources of profitability. 2428.TW's ROE of 16.8% is driven by Asset Turnover (0.525), indicating efficient use of assets to generate revenue.

Graham-Dodd Adjusted Valuation

Our adaptation of Graham's growth formula (Fair P/E = 8.5 + 2g) from The Intelligent Investor. The classic version relies on analyst growth projections, which can be unreliable. This adjusted model substitutes the company's realized 3-year EPS CAGR — a backward-looking, verifiable measure of actual earnings power — grounding the valuation in demonstrated performance rather than forecasts.

Two adjustments we make, and why. Growth is capped at 15%. Graham defined g as expected growth over the next seven to ten years, not last year's rate. Across US companies since 1994 the median realized 7-year EPS growth is 5–8% regardless of how fast a company grew beforehand, and of 4,457 company-quarters that grew faster than 200%, none sustained it. Uncapped, the formula assigned fair multiples in the hundreds to companies that had never held that rate — and scored worse than simply reading the P/E. Capped, it carries real information. The verdict has three states, not two. Tested over 377,249 stock-months, this ratio only separates outcomes at its extremes: below 0.25 beat the universe by 1.3 points a year, above 3.0 lagged by 2.7, and everything in between sat inside a one-point band. Rather than call two-thirds of the market "undervalued" on a threshold of 1.0, we say Neutral where the model cannot tell — which is most of the time.

Assessment

Neutral

Graham's classic formula uses analyst-projected growth to estimate a fair P/E (8.5 + 2g). Our adjusted version replaces that projection with 2428.TW's realized 15.0% 3-year EPS CAGR, capped at 15% — demonstrated performance rather than forecasts, held to a rate companies have historically sustained. 2428.TW actually compounded EPS at 15.2% over three years; the model uses 15%, the highest rate it will extrapolate — of 4,457 company-quarters that grew faster than 200%, none sustained it over the following seven years. 2428.TW trades at a -42% premium to its adjusted intrinsic value of $541.25, suggesting the market is pricing in future growth beyond what historical earnings support. The adjusted fair P/E of 38.5x compares to the current market P/E of 18.7x.
