Sivers Semiconductors news
Sivers Semiconductors (SIVEF) posted a negative gross margin and never explained it
Sivers Semiconductors booked Q2 net sales of SEK 53.8 million against SEK 73.4 million of cost of goods sold, and the report never discusses the gap. Its two pipeline disclosures imply different starting points. The US line fell about 14% while Stockholm closed before the report landed.
Sivers Semiconductors (SIVEF) reports Q2 Thursday. The market is watching photonics, not the numbers.
Sivers reports Q2 2026 after the Stockholm close on August 27. For a company at this stage, the market is underwriting the photonics business and whether co-developments with GlobalFoundries and Jabil turn into volume, not the quarter's loss, which carries a SEK 42.9 million non-cash charge. A July raise near SEK 700 million cleared the near-term funding overhang.
