Aktie im Fokus: LPKF – das Kursphänomen aus der dritten Reihe

LPKF Laser & Electronics (LPKF) has been one of the strongest performers on the German stock market this year, with a nearly 100% increase in share price since the beginning of the year. This rally, however, has since faded. The Swiss asset manager Bantleon, which also has a corporate office in Hannover, noticed an entry opportunity in LPKF and purchased a 29% stake in the company in 2016, joining the board and pushing for a broader business expansion.

LPKF now develops laser-based manufacturing solutions for the semiconductor, electronics, solar, and medical technology industries.

Bantleon sold its stake in LPKF in May 2020 at a profit. Currently, the largest individual shareholder is AOC Alpha, with a 10.6% capital share. LPKF's stock price has been on a rollercoaster since 2012, fluctuating between just under six euros and 30 euros. From March 31 to May 15, the stock price surged by 400% within a few weeks.

Peter Mümmler, the LPKF financial vice president since April 2025, bought 4,500 shares in March 2025 at 5.95 euros and another 6,000 shares at 7 euros in October 2025. However, the company's executives are already in debt from their recent stock purchases. Mümmler bought 1,500 shares at 14 euros on July 23, 2025, and LPKF CEO Klaus Fiedler bought 1,000 shares at 21 euros on May 19, 2025.

The recent spike in the LIDE (Laser Induced Deep Etching) technology's potential to revolutionize the semiconductor industry has fueled investor hopes. This technology allows for creating ultra-fine structures and through-holes in glass without causing micro-cracks or thermal damage. The LIDE technology could play a crucial role in the next generation of chips for advanced packaging.

However, weak second-quarter results have dampened investor hopes for a semiconductor rebound. Nvidia's recent comments indicate that copper cables in data centers will remain essential, casting doubt on the speed at which companies like LPKF can expand their manufacturing capacity. Additionally, the lack of traction in the solar business and the company's reliance on test environments for its LIDE technology have further eroded investor confidence.
