Sivers Semiconductors: A 67% Monthly Surge Masks the Stakes of an Insider Investigation and a Dilution Vote
04.06.2026 - 04:32:49 | boerse-global.de
The laser arrays are real. The partnership with GlobalFoundries is signed. And the stock has rewarded believers with a 67.86% monthly gain that saw it hit an intraday record of €10.23 before pulling back 18.38% to €8.44 on Wednesday. But behind the photonics euphoria lies a tangle of regulatory scrutiny, short seller accusations, and an extraordinary general meeting that could determine whether the rally has legs — or is simply the prelude to a sharp reversal.
Swedish prosecutors are examining whether confidential information about Sivers’ planned dual listing on Nasdaq New York leaked into the market. The share price jumped roughly 48 hours before the official announcement, a pattern that prosecutor Jonas Myrdal described as “striking” and reminiscent of earlier pump-and-dump cases. An anonymous X account with a large following had already disseminated precise details about the intended New York listing, raising questions about whether the move complies with the EU Market Abuse Regulation. The investigation adds a layer of legal uncertainty to a stock that already carries a one-month annualized volatility of 245.26%.
The short seller community has also taken aim. Ningi Research on June 1 published a report alleging aggressive revenue recognition practices, targeting at least 97 million Swedish kronor — roughly 31% of Sivers’ reported annual sales. According to Ningi, a portion of that revenue may involve products not yet manufactured, and some government research grants may have been booked as commercial sales. While these are allegations from a short seller rather than official findings, they have resonated with a market where nearly 17% of the free float was out on loan at the end of May, up from 1.6% at the start of March.
All of this sets the stage for a pivotal shareholder meeting on June 15 in Stockholm. The board has proposed authorizing the issuance of up to 53.8 million new shares, equivalent to a roughly 15% dilution of existing equity. Proceeds would fund organic growth, potential acquisitions, and the Nasdaq listing. A separate employee stock option program of up to 7 million new options would add another 2% on a fully diluted basis. No dividend is planned for 2025. Shareholders who wish to vote must be registered by June 5 and must confirm attendance by June 9, a tight window that may limit turnout.

The meeting also marks a changing of the guard. Board members Tomas Duffy, Erik Fallström, and Keith Halsey — part of the original Scandinavian founding team — are stepping down. Their replacements, Joakim Nideborn and Helena Svancar, bring financial and international management expertise respectively, aligning with the company’s stated push toward deeper capital markets engagement.
Financially, the picture remains strained. First-quarter revenue fell 22% year on year to 61.9 million SEK, and the adjusted EBITDA came in at minus 13.8 million SEK. The photonics segment, the heart of the GlobalFoundries story, generated only 17.8 million SEK in revenue, a 32% decline, while its segment EBITDA swung to a loss of 7.7 million SEK from a near-breakeven 0.6 million SEK a year earlier. Operating cash flow was negative 49.2 million SEK, and the company ended March with just 26.6 million SEK in cash on hand.
Sivers has been scrambling to shore up its balance sheet. After the quarter closed, it completed a directed share issue of 8.62 million shares, raising about 125 million SEK. It also secured a secured credit facility of $17 million, split between a $5 million term loan and a $12 million convertible note, which was used to repay existing debt. The capital injection provides some breathing room, but the burn rate suggests more financing will eventually be required — especially if the Nasdaq listing proceeds.
The GlobalFoundries deal itself is the cornerstone of the bullish thesis. Sivers’ laser arrays will be integrated into GlobalFoundries’ Silicon Photonics Co-packaged Advanced Light Engine platform, targeting co-packaged optics, linear pluggable optics, and new interconnect solutions for AI data centers. The addressable market for pluggable optics is projected to reach $25 billion by 2030. Yet the announcement contained no order value, no minimum purchase commitment, and no revenue timeline. The company’s pipeline has grown 77% since the end of 2025 to $799 million, and management continues to target 25% to 30% annual growth, though profitability is not expected before 2028.

Adding to the complexity is the position of the largest shareholder, Achilles Capital, which is tied to DDM Finance. DDM is in the midst of a restructuring involving around €225 million in bonds that matured in April 2026. It plans to refinance in the second half of the year, subject to court approval, and is considering selling credit portfolios as well as technology and life-science stakes worth between €30 million and €50 million. Whether the Sivers stake will be included in those sales remains unclear, but the overhang adds another layer of uncertainty.
On June 2, the stock surged more than 50% in a single session, becoming the most traded issue on the Stockholm exchange with turnover exceeding 1.3 billion Swedish kronor. The technical indicators look stretched: the relative strength index sits at 65.6, and the share price trades 127.73% above the 50-day moving average of €3.67. The rally has been breathtaking, but it has also concentrated risk into a handful of unresolved questions. The June 15 AGM will answer whether shareholders are willing to back the board’s expansion plans — or whether the probe and the short seller attacks will give them pause.
