On 3 August 2026, childcare operator Edge Early Learning failed to pay rent on 31 centres it leases from Arena REIT. Three weeks later Edge was in voluntary administration, and roughly 14 per cent of Arena's annual rental income was in question.

That episode is the clearest recent example of why tenant quality matters for landlords. Arena REIT (ASX:ARF) and Charter Hall Retail REIT (ASX:CQR), both S&P/ASX 200 property trusts, show two different answers to the same question: how much income depends on a few tenants, and how strong are those tenants?

The Edge default and what Arena assumed

Arena's FY26 results presentation, released on 21 August 2026 after the result was postponed, said Edge had paid rent in full to 31 July 2026. August rent went unpaid on 3 August and default notices followed on 4 August. The 31 properties, 17 in Queensland and 14 in South Australia, were valued at $219 million, and Arena held about $4 million in bank guarantees as security.

Edge entered voluntary administration on 25 August, with KordaMentha appointed, according to Business News Australia. Administrators said centres would keep operating. Arena reported that it had taken control of two newly developed Edge centres and signed term sheets for new 20-year leases with a national operator.

Arena's guidance for FY27 distributions of not less than 18.0 cents per security, down from 19.25 cents in FY26, assumes no Edge income from 1 August 2026 to 30 June 2027, net of the $4 million security.

Arena's model: long leases, few operators

Arena is an internally managed, stapled REIT that develops, owns and manages social infrastructure, mainly early learning centres (ELCs) plus healthcare properties. At 30 June 2026 it held 297 ELC properties, including 23 development sites, and 10 healthcare properties, with a portfolio value of about $2.0 billion.

Its leases are unusually long. Weighted average Lease expiry (WALE), the average time remaining on leases weighted by income, was 17.5 years, and occupancy was 100 per cent. About 82 per cent of rent reviews over FY27 to FY30 are fixed increases, and like-for-like rent grew 4.0 per cent in FY26.

The trade-off is concentration. Goodstart Early Learning provided 19 per cent of income, Green Leaves Early Learning 16 per cent and Edge 14 per cent, according to The Sector's summary of the results. Arena also tracks operator health: across its stabilised portfolio at 31 March 2026, tenants' Earnings before interest, tax, depreciation, Amortisation and rent covered rent 3.05 times, with average centre occupancy of 76.7 per cent.

FY26 itself was solid. Net operating profit rose 8.3 per cent to $79.1 million, operating earnings were 19.60 cents per security, statutory profit was $131.8 million and net asset value per security was $3.60. Gearing, meaning Debt as a share of total assets, was 24.5 per cent, with 100 per cent of debt hedged and a cost of debt of 4.2 per cent.

Charter Hall Retail's model: many national tenants

Charter Hall Retail REIT is externally managed by Charter Hall Group (ASX:CHC) through Responsible Entity Charter Hall Retail Management Limited, which earns fees calculated by reference to asset values. The trust owns convenience shopping centres and "net lease" retail Assets such as service stations and pubs, where the tenant typically pays most outgoings, in a portfolio valued at $5.2 billion.

Its FY26 results, released on 7 August 2026, reported operating earnings of $153.4 million, or 26.4 cents per unit, up 4.0 per cent. Distributions rose 3.3 per cent to 25.5 cents, statutory profit was $389.4 million and Net Tangible Assets (NTA) rose 8.4 per cent to $5.03 per unit.

Tenant quality here comes from breadth and covenant strength. Major tenants including Woolworths, Coles, bp, Wesfarmers, Aldi, Ampol and Endeavour provided 61 per cent of rental income. Net lease assets reached 49 per cent of income, completing what chief executive Ben Ellis described as the transition towards a 50 per cent target.

Occupancy was 99.1 per cent, WALE was 7.1 years (8.9 years for majors and 10.4 years for net lease assets), and specialty leasing spreads were 4.1 per cent. Supermarket sales grew 3.6 per cent, with 89 per cent of supermarket tenants paying turnover rent.

Measuring concentration side by side

By our calculation, Arena's three largest operators supplied 49 per cent of income (19 + 16 + 14), all in one industry funded partly by government childcare subsidies. Charter Hall Retail's major tenants supplied 61 per cent, but that figure spans ten groups across groceries, fuel, hardware and hospitality, most of them large listed companies.

A second calculation shows the size of Arena's assumption. Excluding Edge for 11 of 12 months implies setting aside about 12.8 per cent of annual rental income (14 × 11 ÷ 12) before the $4 million security. The distribution guidance, by contrast, falls 6.5 per cent (1.25 ÷ 19.25), which suggests other income growth absorbs part of the gap; Arena did not publish that bridge in the material reviewed.

Where the comparison stops working

Long leases protect income only while the tenant can pay. Arena's 17.5-year WALE did not stop the Edge default, while Charter Hall Retail's shorter WALE means more frequent re-leasing but less reliance on any single operator.

Debt settings differ too. Arena's gearing is lower, but its hedges have a weighted term of 2.2 years. Charter Hall Retail reported 30.9 per cent balance-sheet gearing, a 5.0 per cent weighted average cost of debt, and hedging of 67 per cent for FY27 falling to 46 per cent in FY28, so rate moves feed through more quickly.

Charter Hall Retail's fees also depend on asset values, while Arena's costs sit inside the business. Both use June year-ends, so periods align.

The indicators that will test each trust

For Arena, the milestones are the administrators' decisions on Edge, conversion of term sheets into signed leases, and regulator-imposed suspensions at two South Australian Edge centres.

For Charter Hall Retail, watch tenant covenants in the net lease book, re-leasing spreads and the effect of lower hedging on its FY27 guidance of at least 27.3 cents per unit. It has declared a September-quarter distribution of 6.6 cents per unit, payable on 27 November 2026.

Both remain in the S&P/ASX 200, according to iShares IOZ holdings dated 24 September 2026.
