New Zealand‑based infant formula maker a2 Milk trimmed its 2024 revenue and earnings outlook on Thursday, citing shipment slowdowns to its biggest overseas market, China. The company said disruptions in its supply chain, partly linked to the ongoing Iran war, have hampered the flow of product into Chinese distribution channels, prompting the forecast revision. The firm did not disclose the exact size of the shortfall.

Analysts had expected the firm to benefit from strong demand for premium formula where parents increasingly favor protein‑profile products. By pulling back its guidance, a2 Milk signals that the logistical bottleneck could erode sales momentum through the second half of the year, a development that may pressure its share price and invite scrutiny from investors tracking emerging‑market exposure. The downgrade could affect the broader New Zealand dairy index.

The revision arrives as trade routes between Oceania and China face heightened scrutiny, and shipping firms report longer transit times for dairy cargoes. With China accounting for a substantial share of a2 Milk’s export revenue, any prolonged disruption threatens the company’s ability to meet its growth targets. Management plans to explore alternative logistics options to restore flow.
