What Is Changing

On a TTM 2026Q1 basis, ISH is improving on both growth and profitability, painting a notably more positive picture versus the same period — the growth momentum has held across consecutive periods. When both scale and efficiency improve together, this is typically a sign of quality growth.

Financial Highlights

Detailed analysis of each financial dimension

ROE = Profit Margin × Asset Turnover × Equity Multiplier

2025Q1 12.5% = 38.4% × 0.31 × 1.04
2026Q1 15.6% = 40.1% × 0.37 × 1.06

ROE rose from 12.5% to 15.6% — all three components improved, with asset turnover contributing the most.

Net margin: 40.1% +1.7pp Asset turnover: 0.37x +0.06x Leverage: 1.06x +0.02x

Is the profit sustainable?

Margins are improving and earnings quality is solid — a durable foundation for ROE.

very positive positive stable watch under pressure

What is driving the margin?

Net margin expanded to 40.07%, rising 1.7pp. The main driver is Gross margin rose 3.5pp and SG&A / Revenue fell 1.3pp, moving in line with the stronger net margin (in addition, Net financial result / Revenue rose 0.7pp added support while Other profit / Revenue fell 3.3pp remained a drag).

Margin improves from both core operations and non-core items — the core foundation is positive, but the sustainability of non-core contributions needs monitoring.

Profitability trend

Gross Margin 57.08% +3.5pp
SG&A / Revenue 5.17% −1.3pp

TTM YoY · 2025Q1 -> 2026Q1

Is capital being used efficiently?

Capital efficiency for utilities should be read alongside regulated tariffs and long-cycle depreciation — ROIC of 16.1% reflects a large fixed-asset base.

Is capital being deployed efficiently?

ROIC expanded to 16.07%, rising 3.6pp. That translates to 16.07 in after-tax operating profit for every 100 units of operating capital. Both NOPAT margin rose 4.3pp and capital turnover rose 0.05x, with invested capital holding roughly steady — capital-return quality improved from both sides.

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 16.07% +3.6pp
NOPAT Margin 42.38% +4.3pp
Capital Turnover 0.38x +0.05x
Average Invested Capital 592.1bn −10.4bn

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 0.10x equity, net debt at 0.05x equity.

Over the last 12 months, working capital absorbed 11.3bn of cash, mainly because of higher receivables and higher inventories. Part of that drag was offset by higher payables.

Working Capital Drivers

TTM YoY · 2025Q1 -> 2026Q1

Receivables increased → lower CFO: −12.5bn
Inventories increased → lower CFO: −1.9bn
Payables increased → higher CFO: +3.1bn

Working Capital Efficiency

Working capital is being managed more efficiently, supporting overall capital efficiency. Cash conversion cycle improved by 9.5 days versus the same period last year. The main moves came from DIO rose 1.0 days, DSO fell 6.8 days, and DPO rose 3.7 days.

Improvement comes mainly from faster receivables collection — reflects the quality of receivables management.

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

Inventory turnover is slowing

DIO increased by +1.0 days, suggesting more capital is being tied up in inventories.

Working Capital Efficiency

TTM YoY · 2025Q1 -> 2026Q1

Receivables 38.6 days −6.8 days
Inventory 32.1 days +1.0 days
Payables 4.8 days +3.7 days
Cash Conversion Cycle 65.9 days −9.5 days

Is financial risk significant?

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

Leverage & Liquidity

Leverage looks fairly comfortable, with net debt / equity at 0.05x and interest coverage at 112.69x.

At present, short-term debt accounts for 100.0% of total debt, cash equals 4.8% of debt, and total debt stands at 31.2bn.

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

Watchpoints

Short-term refinancing pressure is meaningful

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

Cash buffer is thin relative to debt

Cash / debt stands at 4.8%, leaving limited liquidity buffer to monitor.

Leverage and liquidity trend

Net Debt / Equity 0.05x +0.05x
Interest Coverage 112.69x −60.01x
Cash / Debt 4.8% −58.7pp
Short-term Debt / Total Debt 100.0% 0.0pp
CFO / NI 1.30x −0.36x

TTM YoY · 2025Q1 -> 2026Q1

Cash Flow

With safe leverage noted above, cash flow below shows the self-funding capacity. Operating cash flow reached 116.3bn in 2025, against investing cash flow of -38.9bn.

Post-investment cash flow was positive +77.4bn. Financing cash flow was negative +71.4bn.

CFO / net income was 1.30x.

After spending +1.9bn on fixed-asset investment, the business generated trailing free cash flow of +114.7bn.

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 116.6bn −9.2bn
Cash Capex 1.9bn +1.8bn
FCF TTM +114.7bn −11.0bn

Investment Takeaway

The business is showing brightening signals, but the improvement is still early and not yet thick enough to read as a confirmed trend. The brighter spot is operating efficiency, with net margin improving 1.7 pp. The next item to monitor is capital efficiency, with ROIC at 16.1%. The main risk still sits in leverage and liquidity, with interest coverage at 112.69x.

Improvement: operating efficiency is getting better, with trailing-12M net margin at 40.07% after expanding 1.7pp versus the same period last year.

Watchpoint: Capital efficiency needs cycle context.

Key risk: leverage and liquidity remain a pressure point, with net debt / equity at 0.05x and a thin cash buffer.
