The stock’s staggering 266% year-to-date rally hit a wall last week, but the numbers behind the retreat tell a more complicated story than a simple profit-taking event. LPKF Laser shares slipped 6.78% on Friday to €22.00, capping a weekly decline of 16.03%, after the company posted a sharp drop in first-quarter revenue. Yet a deeper look at the order book provides a potential counterweight: new orders climbed to €24.1 million, pushing the book-to-bill ratio to 1.4 — meaning orders are coming in faster than revenue is being recognized.
The revenue figure itself was sobering. LPKF generated just €17.1 million in sales during the opening quarter of 2026, down from €25.3 million a year earlier. The slide was driven largely by weakness in the Chinese solar business. Adjusted EBIT came in at minus €5.7 million, underscoring the earnings pressure from lower volumes. The company’s “North Star” cost-reduction program helped cushion the blow, and management reaffirmed full-year guidance of €105 million to €120 million in revenue, alongside an adjusted EBIT margin ranging from negative 3% to positive 4.5%.
The core of the investment case remains LIDE, LPKF’s laser-based technology for processing glass substrates in advanced semiconductor packaging. CEO Klaus Fiedler has highlighted multiple global customers still in the qualification phase, and the company anticipates signing first production orders in the second quarter of 2026. Industrial mass production of glass substrates is targeted for 2027, with high-volume output not expected until 2029. That timeline explains why the stock, after touching a high of €28.00, has corrected more than 21% in short order: the market is pricing a future that has yet to be demonstrated operationally.
Broader industry trends lend some support to the thesis. Nvidia and Corning recently announced a multi-year collaboration to develop advanced optical connectivity solutions for AI infrastructure, with Nvidia committing $500 million to Corning. LPKF’s LIDE technology fits directly into the intersection of glass-based packages and optical interconnects — a space that is also drawing investment from TPK Holding and ASE Technology, both of which are advancing through-glass vias and pilot lines. These developments bolster the long-term narrative but do not replace the need for LPKF to convert its testing and development projects into firm series orders.
Should investors sell immediately? Or is it worth buying LPKF Laser?
While waiting for LIDE to deliver, LPKF has been strengthening its financial position. The company extended its syndicated loan agreement until the end of 2028, preserving flexibility for investments and efficiency measures. The North Star program targets a double-digit adjusted EBIT margin by 2028, a goal that will require both cost discipline and revenue growth. For the current fiscal year, management has consciously excluded potential large-volume semiconductor orders from its guidance, meaning any LIDE contract win would serve as an additional upside catalyst rather than a built-in expectation.
Shareholders will gather in Hannover on June 4 for the annual general meeting. Key items on the agenda include approval of the 2025 financial statements, the discharge of management and the supervisory board, and an amendment to the articles of association. The net retained profit of approximately €7.6 million will be carried forward; no dividend is proposed. A notable board change is also on the docket: Dr. Dirk Michael Rothweiler is stepping down after his term, and Dr. Arne Schneider, currently CEO of Elmos Semiconductor, has been nominated as his successor. Schneider’s experience in the semiconductor industry and his familiarity with accounting and audit requirements align well with LPKF’s strategic pivot.
The operational backdrop remains tough. LPKF reported a net loss of €14.3 million on revenue of €115 million for the full year 2025, and the first-quarter results offer no immediate relief on the bottom line. The stock’s 50-day moving average of €12.28 underscores how far the share price has come in a compressed period, and the current distance from that level signals elevated expectations. With volatility clocking in at 147.36%, the shares are prone to sharp swings in either direction.
All attention now turns to the coming weeks. The AGM on June 4 will be followed by a strategy forum on June 18, where CEO Klaus Fiedler is expected to detail the long-term roadmap. Until then, any signal of progress in customer negotiations could reignite the rally, while an absence of concrete orders may deepen the pullback. The 21.43% retreat from the €28.00 peak serves as a reminder that even a compelling technology story can only support so much valuation in the absence of turning that story into revenue. The LIDE narrative remains intact, but the proof will be written in the order book.
