In the upcoming week, three of Singapore's premier blue-chip companies are preparing to hand their shareholders larger dividend payments. Wilmar International (SGX: F34), ST Engineering (SGX: S63), and Sembcorp Industries (SGX: U96) are all increasing their payouts, with increments ranging from 12.5% to as much as 25%.

Although a fatter yield is always appreciated, a board's commitment to disburse more is only as reliable as the cash reserves supporting it. While headline profit figures are impressive, free cash flow remains the essential driver of any dependable dividend.

Interestingly, two of these three Straits Times Index (SGX: ^STI) heavyweights actually registered negative free cash flow in the first half of 2026 (1H2026), highlighting the need to look beyond the revenue surge and scrutinize their balance sheets closely.

ST Engineering: Is the Cash There to Cover the Payout?

ST Engineering stands out as the frontrunner in terms of pure cash coverage. The Temasek-backed defence and aerospace firm operates through three divisions: Commercial Aerospace, Defence & Public Security, and Urban Solutions & Satcom.

The company posted an exceptional first half, with revenue increasing by 11.1% to S$6.6 billion and net profit surging 27.1% to S$512.1 million. Notably, earnings growth outpaced revenue growth across all three business segments.

Critically, free cash flow climbed 22.1% to S$591.6 million, easily exceeding reported profits and offering a solid cushion for the declared S$0.05 interim dividend scheduled for payment on 4 September. The group previously distributed S$0.04 on 11 June 2026, bringing first-half dividends to S$0.09, up from S$0.08 a year earlier.

With a record order book valued at S$35.7 billion, ST Engineering is producing more than sufficient organic cash to support its 12.5% year-on-year (YoY) dividend increase.

Wilmar International: Can the Largest Increase Be Sustained?

Wilmar is implementing the most substantial percentage boost, raising its payout by 25% to S$0.05 per share, although its cash position warrants a closer examination. The group operates an integrated agribusiness with four segments spanning edible oils, sugar, flour, animal feeds, oleochemicals, biodiesel, plantations, and port services.

Revenue grew 17.2% YoY to US$38.6 billion in 1H2026, while profit before tax rose 12.8% to US$1.1 billion. Core net profit improved by 9.9% to US$641.5 million, but net profit attributable to shareholders saw only a marginal 2.3% increase to US$608.9 million, with a US$38.0 million non-operating loss and an effective tax rate of 38.2% accounting for the gap.

Despite robust revenue growth driven by the consolidation of AWL Agri Business, Wilmar experienced a sharp reversal in free cash flow, swinging from a positive US$1.2 billion to a negative US$157.0 million. This cash outflow was driven by higher inventory costs as palm oil and soybean prices climbed, combined with elevated capital expenditures that reached US$678.8 million.

The group maintained cash and bank deposits of US$8.1 billion against gross borrowings of US$32.2 billion, with net gearing at 0.93 times. Nevertheless, Wilmar declared an interim dividend of S$0.05, up from S$0.04 a year ago, with the payment scheduled for 2 September 2026, leading the trio with its 25% hike.

An inventory build-up is distinct from an earnings collapse, and working capital strains can ease as inventory is converted back into cash. While management anticipates that geopolitical developments will continue to create an uncertain operating environment, it still projects satisfactory full-year outcomes.

Sembcorp Industries: What Supports a 22% Increase?

Sembcorp Industries presents a comparable scenario following its aggressive expansion. Majority-owned by Temasek Holdings, the company supplies energy and develops renewable, urban, and water infrastructure across Asia, the Middle East, the UK, and Australia.

Revenue climbed 28% YoY to S$3.8 billion in 1H2026, driven by higher energy prices in Singapore's Gas and Related Services division. Sembcorp also finalised the Alinta acquisition on 1 June 2026, contributing one month of earnings.

The energy provider raised its interim dividend by 22% to S$0.11 per share, despite net profit dropping 72% to S$150 million, largely attributed to S$155 million in one-off transaction costs linked to the Alinta purchase. This significant acquisition also expanded borrowings to S$15.2 billion and pushed free cash flow into negative territory at minus S$39 million, while cash and cash equivalents stood at S$1.3 billion.

Management is counting on full-period contributions from Alinta and a new 600 MW hydrogen-ready plant to fuel a significantly stronger performance in the latter half of the year.
