What Is Changing

On a TTM 2026Q1 basis, SII posted a very sharp profit drop versus the same period, showing that pressure has clearly fed through to the bottom line. More notably, most of the profit comes from non-core sources — this needs careful evaluation before concluding on growth quality.

Financial Highlights

Detailed analysis of each financial dimension

ROE = Profit Margin × Asset Turnover × Equity Multiplier

2025Q1 52.6% = 229.1% × 0.11 × 2.10
2026Q1 3.9% = 19.6% × 0.10 × 1.95

ROE fell from 52.6% to 3.9% — all three components weakened, with net margin being the main drag.

Net margin: 19.6% -209.6pp Asset turnover: 0.10x -0.01x Leverage: 1.95x -0.15x

Is the profit sustainable?

Margins are under pressure while earnings still rely significantly on non-core sources.

very positive positive stable watch under pressure

What is driving the margin?

Net margin fell to 19.56%, losing 209.6pp. The main pressure is Gross margin fell 0.5pp, outweighing the improvement in SG&A / Revenue fell 0.5pp (in addition, Other profit / Revenue rose 0.7pp added support while Net financial result / Revenue fell 206.1pp remained a drag).

The pressure comes from non-core items while core operations hold their rhythm — margin has a basis to recover once this factor passes.

TTM YoY · 2025Q1 -> 2026Q1

Watchpoints

Financial result share remains high

Even though contribution decreased by 205.5pp, financial result still accounts for 160.8% of PBT — earnings durability should be monitored in coming periods.

Is capital being used efficiently?

Capital efficiency for utilities should be read alongside regulated tariffs and long-cycle depreciation — ROIC of 2.6% reflects a large fixed-asset base.

Is capital being deployed efficiently?

ROIC fell to 2.63%, losing 31.2pp. That translates to 2.63 in after-tax operating profit for every 100 units of operating capital. The main pressure came from NOPAT margin narrowed 210.0pp, outweighing the movement in capital turnover; while invested capital rose by 200bn.

For utilities, ROIC reflects returns on a large fixed-asset base — this is a reference signal and should be read alongside regulated tariffs.

CAPITAL EFFICIENCY TREND

TTM YoY · 2025Q1 -> 2026Q1

ROIC 2.63% −31.2pp
NOPAT Margin 18.35% −210.0pp
Capital Turnover 0.14x −0.00x
Average Invested Capital 2,029.3bn +199.7bn

Balance Sheet

ROIC for utilities reflects a large fixed-asset base and regulated tariffs — the balance sheet below adds perspective. Capital structure is conservative with low leverage — liabilities at 0.98x equity, net debt at 0.45x equity.

Over the last 12 months, working capital released 72.3bn of cash, mainly thanks to lower receivables and higher payables. Pressure from higher inventories only partly offset that benefit.

Working Capital Drivers

TTM YoY · 2025Q1 -> 2026Q1

Receivables decreased → higher CFO: +27.7bn
Inventories increased → lower CFO: −7.3bn
Payables increased → higher CFO: +51.9bn

Working Capital Efficiency

Cash conversion cycle lengthened by 194.1 days versus the same period last year. The main moves came from DIO fell 2.6 days, DSO fell 29.5 days, and DPO fell 226.2 days.

Working capital cycle lengthened mainly due to shorter payment timing — may reflect pressure from suppliers.

For utilities, working capital cycle reflects regulated pricing mechanics and long-term settlement contracts — DSO/DIO/DPO should be treated as contextual signals rather than pure efficiency indicators.

Watchpoints

Cash conversion cycle is lengthening

CCC is up by +194.1 days, indicating weaker working-capital turnover versus the prior year.

Working Capital Efficiency

TTM YoY · 2025Q1 -> 2026Q1

Receivables 23.7 days −29.5 days
Inventory 21.2 days −2.6 days
Payables 40.0 days −226.2 days
Cash Conversion Cycle 5.0 days +194.1 days

Is financial risk significant?

Financial risk is low — leverage is safe, both CFO and FCF are positive.

Leverage & Liquidity

Leverage warrants monitoring, with net debt / equity at 0.45x and interest coverage only at 1.17x.

At present, short-term debt accounts for 44.2% of total debt, cash equals 3.3% of debt, and total debt stands at 686.2bn.

Leverage for utilities reflects long-term capital needs for fixed assets and recovery through regulated pricing — elevated leverage is structural to the industry.

Watchpoints

Interest coverage is thin

Interest coverage is 1.17x, leaving limited room to absorb financing costs.

Cash buffer is thin relative to debt

Cash / debt stands at 3.3%, leaving limited liquidity buffer to monitor.

Leverage and liquidity trend

Net Debt / Equity 0.45x +0.11x
Interest Coverage 1.17x −4.43x
Cash / Debt 3.3% −31.1pp
Short-term Debt / Total Debt 44.2% +4.8pp
CFO / NI 1.94x +0.58x

TTM YoY · 2025Q1 -> 2026Q1

Cash Flow

With safe leverage noted above, cash flow below shows the self-funding capacity. Operating cash flow reached 167.2bn in 2025, against investing cash flow of -368.6bn.

Post-investment cash flow was negative +201.4bn. Financing cash flow was negative +62.4bn.

CFO / net income was 1.94x.

After spending +60.5bn on fixed-asset investment, the business generated trailing free cash flow of +36.4bn.

For utilities, high capex and long investment cycles are structural — short-term FCF volatility does not reflect long-term cash generation through regulated pricing.

Cash Conversion

TTM Cash Conversion · 2025Q1 -> 2026Q1

CFO TTM 96.9bn −742.0bn
Cash Capex 60.5bn +33.8bn
FCF TTM +36.4bn −775.9bn

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. Even so, earnings quality still needs closer monitoring because net financial result remains elevated. The main risk still sits in core profitability, with net margin down 209.6 pp.

Watchpoint: cash flow is currently keeping pace with accounting earnings, with CFO / net income at 1.94x. Even so, net financial result still accounts for 154.6% of PBT, so the earnings mix still needs monitoring.

Key risk: profitability remains under pressure, with trailing-12M net margin at 19.56% after a 209.6pp decline versus the same period last year.
