Sivers Semiconductors Faces a Pivotal Week as Insider Probe, Capital Raise, and US Listing Collide

Swedish photonics firm Sivers Semiconductors navigates insider trading investigation, dilutive share issue, and short seller pressure after a 255% stock surge.

A dizzying rally that sent Sivers Semiconductors’ stock soaring 255% in just 30 days has given way to a period of intense scrutiny. The Swedish photonics firm is now navigating a criminal investigation, a planned capital injection, and a delayed annual report — all while short sellers circle at levels rarely seen in European markets.

Shareholders gather for an extraordinary general meeting on Monday to vote on a targeted share issue worth approximately 125 million Swedish kronor. The company plans to issue 8.62 million new shares at 14.50 kronor each, a move that would dilute existing holders by roughly 2.5%. Institutional investors DNB and Storebrand have already pledged their participation. CEO Vickram Vathulya intends to channel the proceeds into product development and sales efforts.

The capital raise comes at a critical juncture. Sivers’ cash reserves have dwindled to around 44 million kronor, while its net loss ballooned to 186.5 million kronor last year. Revenue climbed nearly 33% to roughly 361 million kronor, but the company’s spending on next-generation optical transceivers for AI data centers has outpaced income growth.

On the operational front, there are bright spots. The company recently expanded its partnership with US-based Tachyon Networks through a $1.5 million deal targeting the fixed wireless access market, supplying combined transceiver solutions. Sivers is also developing a new optical transceiver jointly with Jabil, tapping into a fast-growing market for high-speed components. But competition is fierce — Nvidia recently poured $2 billion each into photonics specialists Lumentum and Coherent.

Criminal probe casts a long shadow

Away from the trading floor, Sweden’s Economic Crime Authority is investigating potential insider trading. A prosecutor is examining whether confidential details about Sivers’ planned secondary listing on the Nasdaq in New York were leaked ahead of time. If illegal information leaks are proven, the US listing ambitions could face serious delays.

The Nasdaq plans have already thrown the financial calendar into disarray. Sivers has postponed the release of its 2025 annual report to mid-May, as auditors need extra time to align the accounts with the stricter standards of the US Public Company Accounting Oversight Board. The company describes the adjustments as immaterial, but the delay has pushed the regular annual general meeting back to mid-June. The first-quarter results are due five days after the annual report, on May 20.

Short sellers pile in

The market’s reaction has been visceral. On Friday, the stock tumbled over 12% in Stockholm to 43.52 kronor, wiping out a chunk of the spectacular gains that had seen it massively outperform global equity indices over the past six months.

At 31 times sales, Sivers trades at a valuation far above the European photonics sector average of roughly four times revenue. That premium has attracted a swarm of short sellers. Voleon Capital Management recently disclosed a net short position exceeding 0.5%, and total short interest now stands at more than 6% of outstanding shares — a level that signals deep skepticism about the company’s ability to justify its market price.

Some academics have poured cold water on the technology story. Researchers including Richard Schatz and Peter Andrekson argue that Sivers’ optical technology does not represent a genuine competitive advantage, noting that similar approaches have existed for years.

The coming days will deliver hard data. Monday’s vote determines whether the company secures the liquidity needed to keep its AI-focused product development on track. If approved, attention shifts to the audited annual report on May 15, followed by the first-quarter numbers five days later. Each milestone will test whether Sivers can back up its lofty valuation with concrete financial performance — or whether the short sellers’ thesis proves correct.
