Hexatronic's Record Quarter Lands in a Sold-Out Fiber Market — While the Tape Sells AI Data Centers

Hexatronic: a corner turned, just as the tape turns away

Hexatronic's Q3 2026 is, on the numbers, the cleanest quarter the company has printed in years. Net sales of SEK 2.5bn were an all-time high and carried 17% organic growth, spread across all three business areas rather than concentrated in one. Adjusted EBITDA of SEK 281m nearly doubled, the margin went from 7.7% to 11.3%, and net debt leverage fell from 1.7x to 1.3x in a single quarter. None of that is ambiguous.

But the framing management chose is more interesting than the beat itself. Rikard Fröberg opened not with the data center boom but with the process: “a quarter that demonstrates that the plan that we embarked on last year is working” — Rikard Fröberg, Group CEO · 2026-10-22. The Performance Improvement Program launched a year ago is now the load-bearing element of the equity story — three consecutive quarters of sequential EBITDA growth, cost savings fully activated in Fiber Solutions, and a business mix that has quietly rebalanced. Fiber Solutions is a little over half of revenue but only 45% of profit; data center is approaching 30% of sales and 40% of profit. That is a fundamentally different company than the one that entered 2025.

The Clinton reversal is the real tell

Among all the numbers, one decision matters most: Hexatronic cancelled its previously planned downsizing of the Clinton facility. This is not a guidance tweak. It is a capacity decision being un-made, and it came with a SEK 67m reversal of a previously recognised impairment — SEK 71m of non-recurring items in total. Companies do not reverse restructuring impairments because they feel optimistic; they do it because the lines filled faster than the model said they would.

The CEO was explicit about the mechanism, and notably named the U.S. subsidy programme:

we see the BEAD business growing faster than anticipated in The US, and have therefore decided to cancel the previously planned downsizing of 1 of our facilities there. We are simply filling up the lines faster than we expected.

The BEAD business is doing the work here, and it is spilling into adjacent demand: transport network investment tied to data center build-out lifted North American Fiber Solutions sales 51%, enough that North America is now Hexatronic's largest region for the first time. Asked point-blank about U.S. capacity utilisation, Fröberg declined — “it is improving, and it is improving a bit more than we had anticipated” — Rikard Fröberg, Group CEO · 2026-10-22 — which is as close to a capacity constraint confession as disclosure rules allow.

The divergence: a boom the market is fading

Here is where this report gets genuinely awkward. Hexatronic's data center area posted SEK 692m of sales, up 107% overall and 44% organically, with EBITDA up 108%. And yet the market's own pricing of the AI data center theme has rolled over hard: six advancers against forty-eight decliners over the trailing 30 and 90 days, a roughly 5.6% negative return. The adjacent plumbing themes have de-rated in sympathy — high bandwidth memory down nearly 7%, co-packaged optics down better than 5%, gigabit-per-second optics and PCIe Gen 6 each off some 7% in ninety days. The 360-day picture is still strongly positive, but the last quarter has been a systematic fade.

So the company is delivering its best data center quarter into a tape that has spent three months voting the other way. Management seems aware of the asymmetry and pre-emptively defused it: Q3 contained two larger hyperscaler projects plus the school-district seasonality of the recently acquired Superior business, and the CEO pointed analysts away from extrapolation — “Q3 was exceptional, so we cannot expect a full repeat of that quarter” — Rikard Fröberg, Group CEO · 2026-10-22. He also volunteered that customers should reference H1/Q2 as the guide to the go-forward run rate. That is unusually candid sandbagging, and it cuts both ways: it protects the stock from a Q4 air-pocket, but it also concedes the organic number is not the new baseline.

The customer mix argues for durability over momentum. The cloud segment — which includes AI customers but also ordinary hyperscalers and colocation storage buyers — is roughly a third of the area; enterprise is just under a third; and the remainder is smaller customers that the recent acquisition strategy has pushed into schools, airports and hospitals. All three grew organically. Hexatronic is a picks-and-shovels supplier to a boom, not a levered bet on one customer cohort.

The scarcity nobody priced

The most under-discussed item on this call was a supply constraint. Glass fiber is sold out. Prices have risen materially, lead times have lengthened, and Hexatronic is openly capacity-constrained on connectors and fiber alike:

Especially the fiber market is kind of sold out. If we had more glass fiber in this quarter, we could have sold more.

Management frames this as a limit on growth rather than a major risk, and the forward supply map supports the calm short term but not the calm medium term:

starting the first quarter of 2027, there is supply coming, new supply coming to the market to the tune of I think, 10% to 15% globally and then another 20% to 25% capacity increase in the second quarter globally.

New new capacity arriving from China in H1 2027, sold into a U.S. market that is increasingly accepting Chinese fiber because there are no alternatives, is a textbook setup for a margin rollover. Hexatronic is doing the right thing — expanding capacity in connectivity products and assemblies, investing behind Jovo in Germany — but the pricing tailwind inside Harsh Environment and Fiber Solutions has a shelf life, and the market has not yet had to price that.

The other drag is geopolitical. Harsh Environment grew 6% organically and delivered a record SEK 43m of EBITDA, but the split is ugly: defense and industrial connectivity demand is outstripping supply, while dynamic cables — the oil and gas book — stays muted because customers are holding CapEx on Middle East conflict uncertainty. That exact phrase was one of the most-spiked global keywords in the market two quarters ago; it is now showing up as a quiet revenue drag inside a Swedish cable maker. The same conflict that has been a headline theme elsewhere is a line-item headwind here.

The verdict

What changed at Hexatronic is not the narrative — it is the evidence. A restructuring impairment was reversed, a closure was called off, leverage fell four-tenths of a turn in ninety days, and the mix shifted toward a business that needs almost no capital (data center capex was 0.7% of sales). The AI customers debate is handled with a pie chart rather than a promise, which is the right instinct.

What did not change is the shape of the market. The theme carrying this quarter is the theme the tape is currently fading, the seasonality is unhelpful into Q4, European fiber-to-the-home remains subdued, and a wall of new glass fiber supply arrives in the first half of 2027. Even the lightest moment on the call — Antarctic neutrino cables that once earned a Nobel Prize in Physics — reads as a reminder that this is an engineering business with long lead times, not a momentum stock. The quarter is real. The multiple may take longer to agree.
