Sivers Semiconductors: A 60% Surge, a Board Makeover, and the Search for Real Revenue

Sivers stock surges 60% after GlobalFoundries silicon photonics partnership, but no order value or timeline disclosed. Analysts flag cash burn and declining revenue.

The excitement around Sivers Semiconductors’ tie-up with GlobalFoundries has been electric — but the numbers that matter most are still missing. Shares in the Swedish chipmaker rocketed 60% on Tuesday in Stockholm to 97.45 kronor, and the stock briefly became the most heavily traded equity on the exchange with turnover exceeding 1.3 billion kronor. On a one-month view, the gain stands at 67.86%. Yet beneath the euphoria, the company has disclosed no order value, no minimum volume commitment, and no timeline for when the partnership will translate into hard revenue.

The collaboration centers on integrating Sivers’ laser arrays into GlobalFoundries’ Silicon Photonics platform to develop reference designs for co-packaged optics, linear pluggable optics, and advanced interconnects — technologies seen as critical to slashing power consumption in AI data centers. GlobalFoundries itself added heft to the story this week by joining the US Department of Energy’s “Genesis Mission,” a program that gives it access to design resources and fabrication platforms for turning AI chip designs into silicon prototypes. Silicon photonics for data centers and quantum computing are explicit priorities, giving Sivers a path into high-volume manufacturing.

But the market is already pricing in delivery. The stock gave back some of its gains on Wednesday, trading at 8.44 euros in Germany — down 3.6% on the day — after seesawing between a 12.5% gain and an 8.4% loss in Stockholm. The relative strength index sits at 65.4, while annualized volatility is a staggering 245%. Analysts point to a broader shortage of optical laser components: researcher TrendForce expects production capacity for EML and CW-DFB laser diodes to double by 2026, driven solely by AI data centers.

Against this charged backdrop, Sivers is also reshaping its boardroom. The nomination committee has proposed Joakim Nideborn, an experienced CFO, as a new member and vice-chairman, alongside Helena Svancar, who brings more than 20 years of experience in strategy and M&A. Outgoing directors include Tomas Duffy, Erik Fallstrom, and Keith Halsey. The overhaul is clearly designed to sharpen the strategic focus on photonics for AI and millimeter-wave technology for satellite communications.

The quarterly numbers, however, remind investors that the company is still burning cash. In the most recent quarter, Sivers posted group revenue of 61.9 million kronor — down 22% year on year — with an adjusted EBITDA loss of 13.8 million kronor. The photonics segment was particularly weak: sales fell 32% to 17.8 million kronor, and segment EBITDA worsened to a loss of 7.7 million kronor, compared with a loss of just 0.6 million kronor a year earlier. The company blamed currency effects and delays in defense-related approvals.

Cash and financing are pressing concerns. At the end of March, Sivers had 26.6 million kronor in available funds, while operating cash flow consumed 49.2 million kronor during the quarter. Since then, the company completed a directed share issue of 8.62 million shares, raising about 125 million kronor before fees, and secured a secured credit facility worth $17 million — consisting of a $5 million term loan and a $12 million convertible note — used to refinance existing debt.

The path forward is clear but steep. Sivers must convert its placement on GlobalFoundries’ platform into purchase orders, deliveries, and ultimately photonics revenue growth. The addressable market for pluggable optics is projected to reach $25 billion by 2030, and every watt saved in AI data centers counts. But with no hard commitments disclosed, the stock’s next move depends on whether the board revamp and the GlobalFoundries deal can start closing the gap between euphoria and earnings. The next quarterly report will offer the first real test.
