LPKF Laser: After a 284% Surge, a 17% Plunge Brings the Hype Back Down to Earth

The stock market’s love affair with LPKF Laser turned sour on Tuesday as the shares suffered their worst single-day drop in years. The sell-off accelerated through the session, initially sliding nearly 12% to €24.80 before deepening to a 17.79% rout that left the stock at €23.10. Just a day earlier, the equity had touched a fresh five-year high of €28.10, capping a rally that had seen it soar 284% since the start of the year and 136.68% over the past 30 days alone.

What triggered the reversal was a collision of soaring expectations with stubbornly weak fundamentals. The company’s first-quarter results for its fiscal 2026 laid bare the gap between the narrative and the numbers. Revenue tumbled 32.4% year-on-year to €17.1 million, dragged down by continued investment caution in the solar segment. The bottom line remained deep in the red: reported EBIT came in at minus €6.9 million, compared with a loss of €3.9 million a year earlier. Even after stripping out restructuring costs, the adjusted operating loss stood at €5.7 million.

The previous year’s full-year net loss of €14.3 million already provided a sobering backdrop. Now, with the Q1 figures confirming no near-term inflection point, the market is beginning to price in a longer-than-anticipated turnaround.

Management’s response is the “North Star” restructuring programme, a sweeping cost-reduction and repositioning effort. The plan calls for the closure and consolidation of production capacity, notably at LPKF’s Fürth site, where the downsizing is proceeding on schedule. The ultimate target is a sustainable double-digit EBIT margin by 2028. For 2026, however, the road is bumpy: the company expects revenue of between €105 million and €120 million, and its adjusted EBIT margin to range from minus 3.0% to plus 4.5% — hardly a recipe for the valuation the stock had commanded.

Should investors sell immediately? Or is it worth buying LPKF Laser?

The recent rally owed much to an external catalyst: Nvidia’s decision to invest $500 million in Corning, a US specialist in glass-based optics that the chip giant plans to use as a substitute for copper cables in its AI systems. LPKF’s LIDE (Laser Induced Deep Etching) technology is seen as the enabling tool for structuring the glass substrates that such applications would require. The logic is plausible, but the timeline suggests it will be years before this translates into meaningful revenue. LPKF is in advanced discussions with multiple customers about a production ramp-up in advanced packaging, yet the first high-volume revenue is not expected before 2029, with volume orders unlikely before 2027.

For the current fiscal year, the board explicitly rules out any material contribution from semiconductor-related orders. The order inflow in Q1 did offer a bright spot — climbing to €24.1 million, delivering a book-to-bill ratio of 1.4, with particular strength in the development and electronics segments. But the short-term orders cannot mask the structural issues in the core business.

Analyst scepticism is mounting. Montega, a respected German research house, rates the stock a “Hold” with a price target of just €15.00, more than a third below Tuesday’s closing level. The firm warns that the current share price already discounts multiple positive scenarios that are far from guaranteed.

LPKF Laser at a turning point? This analysis reveals what investors need to know now.

Investors will have their next opportunity to press management for concrete answers on June 4, when LPKF hosts its annual general meeting in Hanover. No dividend is on the agenda. Two weeks later, CEO Klaus Fiedler is due to present the long-term strategy at an investor forum, where the likely hot topic will be the status of the LIDE qualification process with potential clients. Any sign that those talks have stalled could trigger another sharp leg lower.

For now, LPKF’s stock embodies a classic tension: it has run ahead of its own fundamentals, pricing in profits that may not materialise for another three years. Tuesday’s plunge was not a reality check — it was the start of one.
