What Is Changing

On a TTM 2026Q1 basis, SED is losing revenue quickly, though margins have not been hit proportionally yet — margins have been compressing consistently over multiple periods. This only holds if margins can continue to resist — if revenue stays weak, margin pressure will build.

Financial Highlights

Detailed analysis of each financial dimension

ROE = Profit Margin × Asset Turnover × Equity Multiplier

2025Q1 18.5% = 4.5% × 2.33 × 1.77
2026Q1 10.5% = 3.4% × 1.94 × 1.61

ROE fell from 18.5% to 10.5% — all three components weakened, with asset turnover being the main drag.

Net margin: 3.4% -1.1pp Asset turnover: 1.94x -0.39x Leverage: 1.61x -0.16x

Is the profit sustainable?

Margins narrowed but earnings quality remains clean — pressure is mainly operational.

very positive positive stable watch under pressure

What is driving the margin?

Net margin narrowed to 3.36%, falling 1.1pp. The main pressure is SG&A / Revenue rose 3.1pp, outweighing the improvement in Gross margin rose 1.6pp (with lingering pressure from Net financial result / Revenue fell 0.2pp).

The pressure comes from core operations — this is a concerning type of decline, not a one-off movement.

Is capital being used efficiently?

Capital efficiency is declining — check whether the drag is from margins or turnover.

Is capital being deployed efficiently?

ROIC fell to 10.55%, losing 7.2pp. That translates to 10.55 in after-tax operating profit for every 100 units of operating capital. Both NOPAT margin narrowed 1.3pp and capital turnover fell 0.68x, with invested capital holding roughly steady — pressure came from both operational efficiency and asset efficiency.

Both margin and turnover weakened — this is a broad-based decline, and cyclical versus structural components need to be separated.

Capital Turnover 3.30x −0.68x
Average Invested Capital 326.8bn −4.0bn

Balance Sheet

ROIC declined — the balance sheet shows how capital is being deployed. Balance sheet is exceptionally sound — liabilities at 0.62x equity, with a net cash position equivalent to 0.07x equity.

Inventory ended the period at 189.9bn, roughly 33.4% of total assets.

Over the last 12 months, working capital released 0.0bn of cash.

Working Capital Efficiency

Cash conversion cycle lengthened by 30.1 days versus the same period last year. The main moves came from DIO rose 14.8 days, DSO rose 18.9 days, and DPO rose 3.6 days.

Working capital cycle lengthened mainly due to slower receivables collection — receivables quality needs monitoring.

Watchpoints

Cash conversion cycle remains stretched

CCC stands at 151.1 days, suggesting that working capital remains tied up for a relatively long operating cycle.

Receivables collection is slowing

DSO increased by +18.9 days, pointing to slower receivables turnover.

Is financial risk significant?

Financial risk is low — the company has net cash and CFO reached 64.1bn.

Leverage & Liquidity

Leverage looks fairly comfortable, with net debt / equity at -0.07x and interest coverage at 8.18x.

At present, short-term debt accounts for 100.0% of total debt, cash equals 137.4% of debt, and total debt stands at 61.5bn.

Watchpoints

Short-term refinancing pressure is meaningful

Short-term debt accounts for 100.0% of total debt, raising near-term refinancing needs.

Cash Flow

With safe leverage noted above, cash flow below shows the self-funding capacity. Operating cash flow reached 64.1bn in 2025, against investing cash flow of 3.0bn.

Post-investment cash flow was positive +67.1bn. Financing cash flow was negative +6.2bn.

CFO / net income was 0.70x.

Cash capex or FCF data is incomplete, so the cash-conversion view is only partial.

Investment Takeaway

The business is showing a few weaker signals, but the current magnitude is not yet clear enough to conclude that this is a broader weakening phase. The brighter spot is earnings conversion is confirmed, with CFO/NI at 0.70x. The next item to monitor is cash generation still needs confirmation. The main risk still sits in working capital is tied up too long in the operating cycle, with CCC extended to 151 days.

Improvement: earnings conversion looks more confirmed, with CFO / net income at 0.70x.

Watchpoint: Cash generation still needs confirmation.

Key risk: working capital remains tied up for too long, with cash cycle at 151.1 days.
