Hexatronic Q1 2026 slides: Data Center drives 49% stock surge

Hexatronic's Q1 2026 results were well received, with the stock surging 49% after Data Center became the largest profit contributor, generating SEK 434 million in sales and 46% of group adjusted EBITA. Although reported net sales fell 10% to SEK 1.7 billion due to FX and Fiber Solutions weakness, the company posted an 8.6% adjusted EBITA margin, SEK 110 million in annualized cost savings, and improved operating cash flow to SEK 29 million. Management also completed the JOWO acquisition and reiterated strength in Data Center and Harsh Environment, supporting a constructive outlook despite continued FX and fiber-related headwinds.

Analysis

The market is re-rating Hexatronic as an infrastructure-adjacent compounder rather than a cyclical fiber supplier. The key second-order effect is mix: Data Center and defense-oriented Harsh Environment now pull the earnings engine toward higher-multiple end markets, which should mechanically compress the volatility of group margins even if top-line growth remains choppy. That matters because peers stuck in legacy fiber buildouts will likely be punished harder on any near-term volume softness, while suppliers into hyperscale and defense should retain pricing power and better order visibility.

The biggest underappreciated catalyst is not the quarter itself but the next 2-3 quarters of operating leverage from the savings program plus FX normalization. If currency stops subtracting from reported growth, the company can show a much cleaner inflection in organic sales and EBITA conversion without needing heroic demand assumptions. The risk is that the current enthusiasm prices in a straight-line transition; if Fiber Solutions keeps shrinking faster than Data Center grows, investors may eventually question whether the new mix is enough to offset structural erosion in the legacy base.

JOWO is strategically logical, but the multiple paid leaves little room for execution slippage. The defense exposure is attractive, yet it also introduces lumpy procurement timing and government-budget sensitivity, so the real test is whether management can turn this into a repeatable platform instead of a one-off tuck-in. On balance, the move looks directionally right but potentially over-enthusiastic after a 49% gap; near-term upside likely requires a second leg of evidence on backlog conversion and margin expansion rather than more narrative.

Key Decisions for Investors

• Take profits into strength on the stock after the post-earnings gap; maintain only a tactical long if shares hold above the post-rally breakout level for 2-3 sessions, as follow-through should come from Q2 margin confirmation rather than headline beats.
• For portfolios able to access the name, pair long Hexatronic exposure with a short in a legacy fiber/cable supplier with more commoditized mix over the next 1-2 quarters; the spread should widen if Data Center and defense continue to outgrow traditional telecom buildout names.
• Buy a modest upside call spread rather than outright equity for the next 2-4 months; the setup is good but already partially repriced, so defined-risk convexity is preferable to chasing spot after a 49% move.
• Watch for an entry on any pullback tied to FX or working-capital noise in the next quarter; those are likely transitory and could provide a better risk/reward if the market overreacts to reported growth volatility.
• If management commentary in Q2 confirms margin expansion in Data Center and stable Harsh Environment order flow, add to the long; if Fiber Solutions deterioration accelerates without offsetting mix improvement, cut quickly because the bear case is a value trap in transition.
