Sivers Semiconductors Balances Insider Divergence, a $4 Billion AI Optics Opportunity, and a Glasgow Capacity Bet

Sivers sees a $4B optical amplifier market for AI data centers and plans a $30M Glasgow expansion, as insider trades and a US listing plan unfold.

Sivers Semiconductors has rarely offered investors a clean narrative, and the past few weeks have been no exception. A fresh addressable market disclosure, a swelling order pipeline, a major manufacturing commitment, and a set of conflicting insider transactions have all landed within a short window — leaving shareholders to weigh genuine operational momentum against a share price that continues to swing sharply.

A $4 Billion Opening in AI Data Center Optics

Buried in the company's interim report roughly a week ago was a growth avenue that had drawn little attention until now. Sivers pegs the addressable market for semiconductor optical amplifiers used in optical switches for AI data centers at $4 billion. These components are designed to help manage the enormous data throughput of modern AI infrastructure more efficiently — territory where Sivers intends to leverage its photonics expertise from indium phosphide manufacturing.

The figure slots into a broader trend. Sivers' total opportunity pipeline stood at $1.2 billion in July, a 268 percent jump compared with the end of 2025. That expansion draws from several sources at once: the newly identified optical amplifier market, ongoing production ramps such as those at Tachyon Networks, and initial program orders from SemiNex. The company is moving through a phase in which development projects are meant to convert into volume-ready product revenue.

Second-quarter figures already hinted at that shift. Product revenue rose 18 percent year over year on a currency-adjusted basis, while total revenue reached SEK 53.8 million. Adjusted EBITDA came in at minus SEK 35.5 million, weighed down in part by a non-cash social security charge of SEK 42.9 million tied to the rising share price. Management attributed the earnings decline to a deliberate reallocation of resources away from development contracts toward upcoming production launches — a strategy that positions 2027 as the decisive year.

Glasgow Expansion Anchors the Industrial Build-Out

Announced about a week ago, a $30 million expansion of the Glasgow manufacturing site fits squarely into that plan. The facility is slated to support annual production of more than 100 million CW-DFB lasers, marking a transition from the previous fab-lite model toward a hybrid manufacturing strategy combining in-house capacity with external foundry partners. For investors, the message is that Sivers is building the industrial base to actually serve rising demand even as it opens commercial markets in optical components.

Insider Trades Cut Both Ways

Running alongside these operational developments, executive dealings have painted a mixed picture. CEO Vickram Vathulya added 70,000 shares in July, bringing his holding to 4,540,076 shares. Chairman Bami Bastani moved the other way: on July 16 he sold 275,000 shares, donated 60,000 to charitable organizations, and gifted a further 70,000 to family members.

Board member Todd Thomson, invested through his firm Headwaters Capital LLC, also trimmed his position. By July 22, Headwaters Capital had disposed of 950,000 shares and transferred an additional 50,000 to a charitable organization.

Such diverging insider activity is rarely clear-cut for investors. The CEO's purchase can be read as a vote of confidence in operational progress, while the sales by the chairman and board member may equally reflect personal liquidity planning or portfolio diversification — without necessarily saying anything about the business outlook.

Bootstrap Europe Exercises Its Options

Adding to the shareholder activity, investor Bootstrap Europe IV exercised all of its subscription options in August, subscribing for 1.66 million new ordinary shares at SEK 4.53 apiece. That funneled roughly SEK 7.5 million into the company. Full exercise by an existing investor is generally taken as a sign of confidence in the company's direction, even though the amount raised remains modest relative to Sivers' operational funding needs.

A Volatile Tape and an Unchanged US Ambition

The stock has been anything but calm. After a 4.7 percent pullback, the shares currently trade at EUR 2.62, having closed at EUR 2.75 on Wednesday. Over the past 30 days the decline totals 30 percent, underlining the high volatility of a name driven lately by news around capacity expansion, order pipeline, and half-year results.

Sentiment has brightened at times, too. The stock was quoted pre-market at EUR 2.80, roughly 16 percent above its level seven days earlier. Even so, it remains 73 percent below its 52-week high of EUR 10.23 — a reminder of how turbulent the revaluation of the growth story has been.

Meanwhile, Sivers continues preparations for a possible secondary listing in the US, targeted to be ready by early 2027. The conflicting insider transactions and the additional capital from Bootstrap Europe IV arrive as the company works on expanding its Glasgow manufacturing capacity and pursues that US listing in parallel.

What ultimately matters for shareholders is whether operational progress — including ongoing production orders for customers such as ALL.SPACE and SemiNex — translates into steadier revenue in coming quarters, after the latest half-year numbers were dampened by timing effects and an extraordinary, non-cash social security charge linked to the strong share price gain during the reporting period. Should the newly opened market for optical amplifiers in AI data centers actually generate orders, it would reinforce the investment case further — provided the company manages the leap from pipeline to dependable revenue.
