UBS Ups LPKF Laser Stake as Stock Retreats From Record High

Swiss bank raises holdings in LPKF as laser stock drops 12% from peak, driven by semiconductor glass-tech potential despite weak Q1 revenue and solar losses.

The UBS Group AG has added to its position in LPKF Laser & Electronics, increasing its holdings to 3.17% of voting rights as the stock pulls back from a 52-week peak reached just days earlier. The Swiss bank now controls 735,476 voting rights from shares and 40,641 from instruments, up from 3.12% previously, according to a filing dated June 18.

The stake increase comes during an extraordinary period for the German laser technology company. LPKF’s shares have surged roughly 344% since the start of the year, hitting an all-time high of €30.20 on June 22. That rally has since lost momentum — by June 24, the stock had slipped to €26.90, an 11% decline. The secondary article pegs the latest close at €26.70, nearly 12% off the peak. Heavy selling volume on the day of the pullback, reaching 194% of the daily average, points to deliberate profit-taking by some investors.

Behind the dramatic share price appreciation lies a fundamental disconnect. LPKF generated first-quarter 2026 revenue of €17.1 million, a steep 33% drop from €25.3 million a year earlier, driven largely by a weak solar business. The company posted an EBIT loss of €6.9 million. Yet the order picture offers a brighter note: incoming orders climbed to €24.1 million from €20.5 million, giving a book-to-bill ratio of 1.4. Management’s full-year forecast targets revenue between €105 million and €120 million, with an adjusted EBIT margin ranging from -3.0% to 4.5%.

The real catalyst for the stock’s ascent remains the semiconductor opportunity, particularly in advanced packaging. LPKF reports ongoing tests of its LIDE glass-processing technology with multiple chip customers and early discussions about production-scale tools. The company has also expanded its offering to include glass package singulation and laser-based bonding of multilayer glass stacks. Critically, LPKF has stated that any potential volume orders from advanced packaging are not factored into its current annual guidance, as the timeline depends on downstream qualification steps.

With the stock now trading more than 160% above its 200-day moving average of €10.26 and 30-day annualized volatility hovering around 132%–133%, the market is pricing in significant future upside. The upcoming half-year report on July 23 will provide a key reality check. Investors will be watching whether the first-quarter order intake translates into recognized revenue and whether the solar segment can stabilize the operational base. Until then, the gap between LPKF’s lofty valuation and its underlying earnings may keep the stock on a volatile path.
