Giantec's profit surge is one-off; core business weakens as HK listing refiled

  • Core profit falls nearly 50% despite headline gain First-half net profit jumped 156% to 525 million yuan, but that came almost entirely from a 432-471 million yuan paper gain on SJ Semiconductor shares. Strip that out and core profit fell 47.3% to 93.47 million yuan, showing the actual chip business is weakening.

    This is the key counterweight: the headline profit is not from operations, so investors should not read it as business strength.

  • Controlling shareholder camp cashed out over 1 billion yuan Entities tied to actual controller Chen Zuotao sold 4.12 million shares in late 2025 and April 2026, raising over 1 billion yuan. Chen was also publicly reprimanded twice by the Shenzhen exchange over related-party issues at another company, a governance red flag.

    Insider selling and governance concerns weigh on investor confidence and can pressure the stock.

  • Hong Kong IPO refiled after first prospectus lapsed The initial Hong Kong listing application lapsed in July, but the company quickly refiled on July 28. A successful H-share listing could bring fresh capital and liquidity, but the lapse and refiling also signal uncertainty and extra cost.

    The refiling is a new capital-markets event that could affect financing and sentiment, though the outcome is still uncertain.

  • Memory chip shipments grow in autos and industrial control The interim report showed rapid shipment growth for high-reliability memory chips used in automotive electronics and industrial control. This is the real operating bright spot, though it was not enough to stop core profit from falling.

    It shows where actual business demand is improving, giving a fair picture alongside the weak core profit.

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.
