This week, three dividend payments are scheduled to land in the bank accounts of Singaporean investors within a 72-hour window.

Singapore Telecommunications will make its payment on 19 August 2026, followed by iFAST Corporation a day later, with Keppel Ltd wrapping up the sequence on 21 August 2026.

While the calendar suggests these three payouts are similar, the financial foundations underpinning each one vary considerably.

Every dividend disbursement draws from cash that the respective business either generated through operations or raised through other means.

A portion of that money may be replenished and paid out again in the following year.

Some of it, however, originates from selling an asset, a transaction that cannot be repeated with the same property.

Free cash flow is the engine that keeps the dividend stream flowing.

The nature of the cash funding the payout is the deciding factor in whether the dividend can be sustained.

These three companies sit at different points along that spectrum of financial sustainability.

iFAST increased its shareholder payout, and the boost was fully backed by higher profits.

Singtel divides its dividend into two parts sourced from different streams, whereas Keppel held its payout steady even as its operating cash flow contracted by more than half.

Where to begin: Is iFAST's payout hike supported by earnings?

iFAST has announced a second interim dividend of S$0.03, marking a 50% increase over the S$0.02 distributed in the same period last year.

The increase was funded by growth in profitability.

Revenue surged 34.8% year on year (YoY) to S$162.0 million in the second quarter of 2026 (2Q2026).

For the first half of the year, revenue climbed 39.3% to reach S$316.5 million.

Net profit attributable to owners rose 40.7% YoY to S$57.9 million for the six-month period.

Assets under administration hit a record high of S$36.13 billion as of 30 June 2026, a 32.8% increase YoY.

Net inflows contributed S$2.56 billion during the half-year.

Recurring net revenue made up 90.2% of the company's non-banking net revenue.

Free cash flow dipped to S$140.9 million in 1H2026, down from S$435.8 million in the prior year.

These two figures are not directly comparable.

Customer deposit movements at iFAST Global Bank are recorded within operating cash flow, and the previous year's baseline included a more substantial increase in deposits.

The company held net cash of S$384.7 million at the end of June.

Management has raised its full-year dividend guidance to S$0.12 per share or higher.

Examining the sources: What is truly financing Singtel's dividend?

Singtel's payment on 19 August represents the final installment of its FY2026 dividend.

That fiscal year concluded on 31 March 2026 (FY2026).

The financial results supporting this payout cover a timeframe that differs from the June-end figures reported by iFAST and Keppel.

Management has declared a total ordinary dividend of S$0.185 per share for FY2026, up 9% from the previous year.

This is split into a core dividend of S$0.134, which is tied to underlying earnings, and a value realisation dividend of S$0.051, funded by capital recycling. Notably, Singtel sold a 0.8% stake in Airtel for S$1.5 billion during the year to support this component.

Underlying net profit increased 12% YoY to S$2.8 billion.

This figure serves as the anchor for the core dividend component.

Group revenue remained steady at S$14.3 billion, as a 2% depreciation in the Australian dollar masked underlying growth.

NCS saw its operating profit jump 34% to S$340 million and secured a record S$3.8 billion in new bookings.

Optus contributed a 23% increase, reaching A$550 million.

Conversely, Singtel Singapore experienced a decline.

Operating profit in that segment fell 4.6% to S$795 million, pressured by intense mobile competition and eSIM-related challenges impacting roaming revenue.

The company's net debt gearing stood at 23.3%.

Assessing sustainability: Can Keppel's cash flow sustain its steady dividend?

Keppel has declared an interim dividend of S$0.150 per share, holding it flat compared to the prior year.

Revenue for 1H2026 rose 24.6% YoY to S$3.8 billion.

The Infrastructure division drove this growth with a 27% increase to S$2.5 billion, following the commencement of commercial operations at the Keppel Sakra Cogen Plant.

Net profit attributable to shareholders dropped 59.0% to S$154.7 million, impacted by a S$375 million loss in the non-core portfolio.

Excluding that portfolio, net profit increased 25% to S$530 million.

Recurring income also grew by 13% to S$467 million.

The key to the dividend question lies in the cash flow statement.

Operating cash flow fell to S$96.8 million from S$219.4 million a year earlier, due to higher working capital requirements.

The company did report a free cash inflow of S$570 million, which includes investing activities and was largely driven by S$1.1 billion in divestment proceeds and dividends received.

To date, Keppel has announced approximately S$1.7 billion in asset monetisation, against a full-year target of S$2 billion to S$3 billion.

Cash on hand stood at S$2.2 billion as of 30 June 2026, compared with borrowings of S$11.3 billion, excluding lease liabilities.
