What Is Changing

On a TTM 2026Q1 basis, TBC has not accelerated revenue sharply, but profitability is improving visibly — earnings have been recovering gradually over multiple periods. Profit growth is driven mainly by better operations rather than scale expansion — a foundation that tends to be more durable.

Financial Highlights

Detailed analysis of each financial dimension

ROE = Profit Margin × Asset Turnover × Equity Multiplier

2025Q1 16.5% = 41.2% × 0.35 × 1.14
2026Q1 21.8% = 48.6% × 0.38 × 1.19

ROE rose from 16.5% to 21.8% — all three components improved, with net margin contributing the most.

Net margin: 48.6% +7.3pp Asset turnover: 0.38x +0.03x Leverage: 1.19x +0.04x

Is the profit sustainable?

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

What is driving the margin?

Net margin expanded to 48.58%, rising 7.3pp. The main driver is Gross margin rose 2.9pp and SG&A / Revenue fell 1.3pp, moving in line with the stronger net margin (with additional support from Other profit / Revenue rose 0.9pp).

The improvement comes from core operations — this is a high-quality margin expansion.

SG&A / Revenue 10.78% −1.3pp

Is capital being used efficiently?

Capital efficiency for utilities should be read alongside regulated tariffs and long-cycle depreciation — ROIC of 21.4% reflects a large fixed-asset base.

Is capital being deployed efficiently?

ROIC expanded to 21.41%, rising 4.6pp. That translates to 21.41 in after-tax operating profit for every 100 units of operating capital. The main driver is NOPAT margin rose 6.6pp, with capital turnover broadly stable; while invested capital rose by 70bn.

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 21.41% +4.6pp
NOPAT Margin 47.75% +6.6pp
Capital Turnover 0.45x +0.04x
Average Invested Capital 1,364.7bn +69.7bn

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 0.12x equity, net debt at 0.04x equity.

Over the last 12 months, working capital absorbed 86.9bn of cash, mainly because of higher receivables and lower payables. Part of that drag was offset by lower inventories.

Working Capital Drivers

TTM YoY · 2025Q1 -> 2026Q1

Receivables increased → lower CFO: −64.2bn
Inventories decreased → higher CFO: +3.0bn
Payables decreased → lower CFO: −25.7bn

Working Capital Efficiency

Working capital is being managed more efficiently, supporting overall capital efficiency. Cash conversion cycle improved by 23.8 days versus the same period last year. The main moves came from DIO fell 2.2 days, DSO fell 17.2 days, and DPO rose 4.4 days.

All 3 drivers (collection, inventory, payables) are improving — working capital turnover is strengthening across the board.

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.

Working Capital Efficiency

TTM YoY · 2025Q1 -> 2026Q1

Receivables 68.7 days −17.2 days
Inventory 10.6 days −2.2 days
Payables 28.7 days +4.4 days
Cash Conversion Cycle 50.6 days −23.8 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 0.04x and interest coverage at 87.88x.

At present, short-term debt accounts for 16.4% of total debt, cash equals 47.0% of debt, and total debt stands at 96.2bn.

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

Net Debt / Equity 0.04x +0.07x
Interest Coverage 87.88x +24.72x
Cash / Debt 47.0% −167.6pp

CFO / NI 1.21x −1.07x

Cash Flow

With safe leverage noted above, cash flow below shows the self-funding capacity. Operating cash flow reached 383.5bn in 2025, against investing cash flow of -252.9bn.

Post-investment cash flow was positive +130.5bn. Financing cash flow was negative +144.6bn.

CFO / net income was 1.21x.

After spending +185.3bn on fixed-asset investment, the business generated trailing free cash flow of +97.6bn.

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 283.0bn −98.9bn
Cash Capex 185.3bn +28.2bn
FCF TTM +97.6bn −127.1bn

Investment Takeaway

The business is heading the right way, but the current picture is still at partial confirmation — not yet a fully clean case. The positive points have clearly improved, showing the operating base is better than before. The brighter spot is operating efficiency, with net margin improving 7.3 pp. The next item to monitor is capital efficiency, with ROIC at 21.4%.

Improvement: operating efficiency is getting better, with trailing-12M net margin at 48.58% after expanding 7.3pp versus the same period last year.

Watchpoint: Capital efficiency needs cycle context.
