Shares of Sivers Semiconductors slid another 2% to $69.05 on Monday, capping a brutal week that saw the stock plunge from $87.55 to as low as $63.35 — a peak-to-trough drop of roughly 28%. The Swedish chipmaker, whose laser and wireless technologies target AI data centers, satellite communications, and defense, is caught in a crossfire of governance turmoil, balance-sheet dilution, and legal risk that is testing whether its eye-popping rally — up more than 3,000% from its 2026 low — has any fundamental underpinning.

  • A Short Seller and Two Law Firms Are Questioning the Revenue Numbers. On June 1, short seller Ningi Research published a report alleging dubious revenue accounting and hollow customer contracts, disclosing a short position in the stock.

Ningi claims roughly 31% of Sivers' reported 2025 revenues are questionable, alleging management classified research grants as commercial sales.

Rosen Law Firm announced an investigation into potential securities claims, alleging Sivers may have issued materially misleading business information, and is preparing a class action. No lawsuits have been filed yet, but the reputational cloud adds a risk premium every day the company stays silent — management has yet to issue a public response to the allegations.

  • Dilution Is Stacking Up While Cash Burns Continue. In April, the board resolved a directed share issue of 8,620,000 new ordinary shares at SEK 14.5 apiece, raising approximately 125 million SEK.

Shareholders have been substantially diluted — a 32% increase in shares outstanding over the past year.

Q1 net sales fell 22% year-over-year to SEK 61.9 million, adjusted EBITDA was negative SEK 13.8 million, and operating cash flow was negative SEK 49.2 million. With less than a year of cash runway, further capital raises remain likely.

  • The Boardroom Reshuffle Signals Deeper Trouble. Three prominent board members — vice-chair Tomas Duffy and founders Erik Fallström and Keith Halsey — stepped down just before the AGM, with departures directly linked to a Swedish economic crime probe into suspected insider trading.

Meanwhile, the head of the wireless subsidiary sold roughly 1.39 million shares in late May for nearly SEK 100 million; no insider has bought stock in three months.

  • The Pipeline Is Huge, but Conversion Is Unproven. Order pipeline has grown 77% since January to $799 million, driven by photonics and radio technology demand.

A concrete $8.2 million production contract with satellite firm ALL.SPACE for deliveries through 2027 offers a tangible proof point. Yet the most valuable parts of Sivers' future are tied to production ramps that haven't started — lidar revenue of up to $138 million depends on a customer beginning mass production in late 2026. Until pipeline converts to cash, the stock is trading on faith — and faith is getting harder to sustain.
