Aurora swings to loss but computing power grows; financing and compensation plan in focus

First-half loss as sapphire drags Aurora expects a net loss of 3.5–7 million yuan for H1 2026, versus a 61.39 million yuan profit a year earlier. Computing power revenue grew and was profitable, but sapphire revenue fell and overall gross profit did not cover expenses. The loss is a negative for the stock.
Directly explains the company's swing to a loss, a key negative price driver.
Related-party computing power deal questioned The Shanghai Stock Exchange asked about Aurora's 95.35 million yuan purchase of computing power from related party Kerong Cloud. Aurora says pricing is fair and it does not control Kerong, but the deal raises governance concerns. This is a mixed signal for the stock.
Highlights a governance risk that could weigh on sentiment, while the company defends it.
Plan to unlock shares tied to old compensation Aurora proposed linking the release of locked shares to payment of long-overdue performance compensation from its 2015 restructuring. The plan could recover some money but the final amount is highly uncertain and needs shareholder approval. This is a mixed factor for the stock.
Addresses a long-standing overhang but with uncertain outcome, affecting investor confidence.
868 million yuan raise for computing power and sapphire Aurora plans a private placement of up to 868 million yuan to fund an Inner Mongolia sapphire base, a western domestic server cluster, and working capital. It also sold 22 servers for 51.5 million yuan, booking a 20.6 million yuan gain. This supports growth but dilutes existing shareholders.
Shows concrete funding and sales progress in computing power, a positive driver despite dilution risk.
