FRANKFURT — LPKF Laser & Electronics SE (LPKF) shares continued their upward trajectory on Monday, jumping 14.92% to €28.50 in delayed Xetra trading, extending a five-day winning streak to approximately 31%. The rally came despite a challenging first-quarter performance that saw revenue fall sharply and operating losses deepen.
The surge was fueled by growing investor enthusiasm for LPKF's Laser Induced Deep Etching (LIDE) technology, which is used to process ultra-thin glass for advanced semiconductor packaging. The company has attributed recent share price momentum to social media discussions about its work in this area. CEO Dr. Klaus Fiedler has noted that LPKF is making "good progress" and is in active discussions with several customers regarding initial production equipment orders.
However, the optimism surrounding the glass technology narrative stands in stark contrast to the company's actual financial results. LPKF reported first-quarter revenue of €17.1 million, down 32% from €25.3 million in the same period last year. The company's EBIT loss widened to €6.9 million from a €3.9 million loss a year earlier. Order intake reached €24.1 million, resulting in a book-to-bill ratio of 1.4.
Analysts have cautioned that the stock's recent rally may be disconnected from underlying fundamentals. Malte Schaumann of Warburg Research noted that "the glass narrative is running ahead of the order book," while Bastian Brach of Montega described the rally as "sentiment-driven" and lacking real fundamental support. Schaumann has a Hold rating on LPKF with a price target of €12.30, while Brach also rates it Hold with a target of €9.00.
Adding to the mix, a regulatory filing revealed that CEO Klaus Fiedler purchased LPKF shares off-market on May 19 at €21 each, for a total investment of €42,000. This insider buying may have bolstered investor confidence, though the stock has since traded well above that level.
The broader market also provided a tailwind, with the DAX index rising approximately 1.7% in delayed Xetra action. Peer company SÜSS MicroTec, another German microelectronics equipment maker, gained 4.03% on Monday, though its advance was significantly more modest than LPKF's.
Looking ahead, LPKF's annual general meeting is scheduled for June 4 in Hanover. Shareholders have submitted counter-motions, including one that opposes approving management's actions for the past year and criticizes the company's "North Star" restructuring plan. LPKF has stated these motions reflect only the authors' views and do not have company endorsement.
LPKF's 2026 outlook calls for revenue between €105 million and €120 million, with an adjusted EBIT margin ranging from negative 3.0% to positive 4.5%. Management has indicated that high-volume advanced packaging orders are not included in this guidance, as their timing depends on downstream qualification processes beyond LPKF's control. The stock's recent gains appear to be pricing in a more rapid adoption of glass-based packaging technology than current orders would suggest, leaving the shares vulnerable to disappointment if the anticipated orders fail to materialize.
