Yandong Micro: insider buying vs. widening first-half loss

  • Controlling shareholder's ally to buy 150–300 million yuan of stock A party acting with the controlling shareholder plans to buy 150–300 million yuan of shares over 12 months, and on August 4 made a first purchase of 170,000 shares (8.59 million yuan). Insider buying signals the owners see long-term value, which supports the share price.

    This is the main positive force behind the stock this period.

  • First-half loss widened to 435 million yuan The 2026 interim report showed revenue up 48.5% to 979 million yuan, but the net loss widened to 435 million yuan from a profit last year, with operating cash flow negative 224 million yuan. A bigger loss and cash burn weigh on the stock.

    This is the main negative force and the key counterweight to the insider buying.

  • Revenue growth and 12-inch/silicon photonics progress, but weak margins Revenue rose for a second straight year and the company says its 12-inch chip line and silicon photonics business are advancing. But gross margin was only 6.54%, so the growth is not yet translating into profit — a mixed signal for the stock.

    It explains the business progress that could eventually justify the valuation, while showing why profits lag.
