LPKF Laser’s June Gauntlet: SDAX Promotion, LIDE Orders and a 40% Rout Collide

LPKF stock slides 15% in seven days, now 40% below May peak. Upcoming CEO speech, SDAX inclusion, and Depaneling Day provide catalysts, but market awaits LIDE production orders to justify rally.

Three weeks. That’s how long LPKF Laser has to deliver the production orders that management promised for the second quarter — and the stock is already pricing in disappointment. After a near-vertical rally that more than tripled the shares from January, the correction has been brutal: the equity has lost roughly 15% in the past seven trading days and now sits almost 40% below its May 25 peak of €30.00.

The calendar compresses rapidly. On 18 June, CEO Klaus Fiedler is scheduled to speak at an SdK investor forum — the first public outing since the annual general meeting. Four days later, on 22 June, LPKF joins the SDAX index after ISS STOXX confirmed the promotion during its regular June review. Passive fund managers will have to adjust their portfolios, giving the stock mechanical demand. And on 24 June, the company hosts a “Depaneling Day” in Garbsen with live demonstrations of its laser technology.

But structure and communication do not replace orders. The market is waiting for concrete proof that the LIDE process — Laser Induced Deep Etching, which uses precision lasers to machine thin glass for semiconductor packaging — can convert pipeline interest into revenue. CEO Fiedler himself bought shares at €21.00 in May, a vote of confidence that has so far failed to stem the slide.

Technical Damage Beneath the Surface

Wednesday’s close of €18.10 leaves the stock just 0.89% above its 50-day moving average of €17.94. A decisive break below that level would open a vacuum all the way down to the 200-day line at €9.46 — a support void that highlights how extreme the recent move has been. The relative strength index at 42.9 shows the stock is weakening but not yet oversold, while annualised volatility of nearly 141% underscores the frayed nerves.

Despite the carnage, LPKF still trades more than 200% higher since January. That explains the gravity: early investors sitting on enormous paper profits are taking them off the table, and two prominent short sellers have piled in. Voleon Capital Management has increased its net short position to 2.13% of the free float, while Marshall Wace maintains a reportable short. When a stock has tripled in five months, the physics of profit-taking make the bear case almost effortless.

LIDE – The Binary Catalyst

Fundamentally, the business remains stretched. First-quarter 2026 revenue collapsed 32% to €17.1 million, hurt by the weak solar segment, and EBIT swung to a loss of €6.9 million. Yet the order intake of €24.1 million translated into a book-to-bill ratio of 1.4, suggesting demand exists even if it is not yet flowing into the top line.

The entire bull case hinges on LIDE. The process targets advanced semiconductor packaging, a market that is already attracting the attention of heavyweights: Nvidia is investing $500 million in Corning to develop glass-based co-packaged optics, a technology that plays directly to LPKF’s strengths. The management has promised first series production orders for LIDE by the end of June. If they materialise, the stock could reclaim its narrative. If they do not, the strongest anchor of the rally — pure speculation on future orders — drags it down.

The company’s official outlook for 2026 envisions revenue of €105–120 million and an adjusted EBIT margin of –3.0% to +4.5%, with large semiconductor-packaging orders explicitly excluded. Any LIDE win would therefore represent pure upside beyond the existing guidance.

Restructuring and the SDAX Wildcard

Internally, LPKF is executing the “North Star” restructuring programme. Production in Suhl has been consolidated, the Fürth site closed, and a consortium credit line extended to 2028. The goal is a sustainable double-digit EBIT margin by that year. These moves improve the cost base but do little to address the immediate revenue gap.

The SDAX inclusion on 22 June adds a mechanical tailwind — index-tracking funds must buy, and the promotion raises LPKF’s profile among institutional investors. Combined with the communication events around the same dates, the period between 18 and 24 June will test whether the stock can stabilise. The market’s true verdict, however, will only arrive with the half-year report on 23 July — unless a confirmed LIDE order lands before then and rewrites the script entirely.
