nib holding's (ASX:NHF) expected upcoming catalysts include the first half of fiscal year 2026 results and government decisions on private health insurance premiums after the company said it's expecting an impact of AU$17 million to its statutory operating profit, according to a Tuesday Jefferies note.

The company on Monday said it expects certain non-recurring one-off items in the fiscal first half of around AU$17 million, which will impact its statutory operating profit, but not its underlying operating profit.

Other catalysts include updates on the nib travel business and further news on insurance claiming rates in both Australia and New Zealand.

"Whilst Government scrutiny of premium rises is expected to continue, industry commentary suggests average premium rises will increase to match health inflation in 2026," the note added.

Jefferies maintained its hold rating on nib holdings and reduced its price target to AU$7.60 from AU$8.60.

The company's shares fell 1% in recent Wednesday trade.
