Atlas Arteria (ASX: ALX)
Atlas Arteria is a global owner, operator, and developer of toll roads, with a portfolio of five toll roads in France, Germany, and the United States.
The defensive-style asset benefits from long-term, predictable, and recurring cash flow, enabling it to pay consistently high dividends to shareholders.
Atlas is due to pay its second-half FY25 dividend to investors next month. It will pay 20 cents per security, unfranked, which equates to a trailing 9.1% dividend yield using the $4.355 share price at the time of writing.
IPH Ltd (ASX: IPH)
IPH provides intellectual property (IP) services through a network of global brands. The group operates across ten jurisdictions in 25 countries, making it the largest IP services provider in the Asia-Pacific region. Its services cover everything from patent filing and trademarks to prosecution, portfolio management, and enforcement. A significant share of its revenue comes from the Asia-Pacific market.
The ASX dividend company consistently generates a strong cash flow from its operations. The company reported cash conversion of 101% in its first-half FY26 results.
It is this strong cash flow that has enabled the company to be an established, reliable dividend payer. It also gradually increases its dividend over time.
IPH paid an interim dividend of 10 cents per share yesterday, up 11.8% on the prior period. The company is expected to pay fully-franked dividends of 38 cents per share in FY26, translating to a dividend yield of 11.7% at IPH's $3.245 share price at the time of writing.
Nine Entertainment Co. Holdings Ltd (ASX: NEC)
Media giant Nine Entertainment underwent a strategic reshape of its business during the first half of FY26. The shift included a broad portfolio restructure involving acquisitions and asset sales, enhancing its digital and streaming revenue.
The ASX dividend company acquired QMS Media, sold Nine Radio, and restructured its NBN and Darwin TV operations. It also sold its controlling stake in property platform Domain.
The $1.4 billion Domain deal allowed Nine to reduce debt, boost its balance sheet, and return roughly $777 million (paying a special dividend at a rate of 49 cents per share) to investors in late 2025.
Nine is due to pay investors an unfranked interim dividend of 4.5 cents per share next month. The company is expected to pay 9 cents per share for the full year, which translates to a dividend yield of 9.88% at its current share price of 89.5 cents a piece.
