The S&P/ASX 200 Index (ASX: XJO) is having a mildly positive session on Tuesday. In afternoon trade, the benchmark index is up slightly to 8,822.7 points.

Four ASX shares that are rising more than most today are listed below. Here’s why they are climbing:

A2 Milk Company Ltd (ASX: A2M)

The A2 Milk share price is up 3% to $6.97. Investors have been buying this infant formula company’s shares this week after it received approval from the State Administration for Market Regulation (SAMR) to transition two China label infant milk formula (IMF) product registrations. A2 Milk’s CEO, David Bortolussi, said: “SAMR approval marks a significant milestone in our China growth strategy and Supply Chain transformation. It supports long-term growth in our core IMF business through market access and innovation, accelerates the development of advanced nutritional manufacturing capability, and captures attractive financial returns through incremental brand contribution and vertical margin capture.”

Calix Ltd (ASX: CXL)

The Calix share price is up 9.5% to 40 cents. This morning, this industrial technology company announced a joint development agreement (JDA) with Ambuja Cements Limited (Ambuja Cements). It is a subsidiary of the Adani Group. The two parties will work together on a commercial scale project at the Sanghi cement plant in Gujarat, India. Ambuja Cements’ director, Karan Adani, said: “The cement industry’s transition to a lower-carbon future will require bold thinking, technological innovation and collaboration across the value chain. Our partnership with [Calix subsidiary] Leilac reflects our commitment to evaluating next-generation technologies that can reduce process emissions while improving energy efficiency and supporting long-term sustainable growth. This initiative aligns with our vision of building world-class manufacturing operations for the future.”

CSL Ltd (ASX: CSL)

The CSL share price is up 2.5% to $115.66. This is despite there being no news out of the biotechnology giant on Tuesday. However, it is worth noting that CSL’s shares have been rebounding from their multi-year low this month. So much so, CSL shares have risen by 22% since the start of the month.

Ioneer Ltd (ASX: INR)

The Ioneer share price is up 18% to 16.5 cents. This morning, the lithium developer announced strategic non-binding letters of intent (LOIs) with the Korea Overseas Infrastructure & Urban Development Corporation and Hyundai Engineering Co. These will see the parties work together to advance the development of the Rhyolite Ridge Lithium-Boron Project. Ioneer’s managing director, Bernard Rowe, said: “Rhyolite Ridge has been a decade in the making — through ongoing partnerships, permitting, and financing. Working with trusted Korean partners with a track record of on-time and on-budget delivery brings us closer to breaking ground and delivering urgently needed lithium and boron. We’re delighted to work with KIND and Hyundai Engineering and look forward to what we’ll accomplish together.”
