Sivers Semiconductors: A 490% Share Rally Creates an Unusual Accounting Headache Ahead of Q2 Numbers

Sivers Semiconductors faces SEK 42.9M non-cash payroll tax charge due to 490% share surge; revenue timing shifts and AI optics deal in focus.

The arithmetic of a soaring share price can sometimes work against a company's income statement. That is the paradox facing Sivers Semiconductors as it prepares to release its second-quarter results this afternoon, with a non-cash charge tied to the very strength of its own stock set to distort the cost line.

The Swedish chipmaker will publish its interim report at 18:00 CET, followed by an investor presentation an hour later. The post-market timing is deliberate, designed to accommodate the growing roster of US institutional investors that now help drive trading in the stock.

A Payroll Tax Quirk Born From a 490% Surge

The headline item in the upcoming report is a SEK 42.9 million non-cash expense for social security contributions, triggered by a revaluation of employee share-based compensation programs. The underlying cause: the company's shares rocketed from SEK 10.71 to SEK 63.15 during the quarter — a gain of roughly 490 percent that dramatically increased the value of the equity-linked awards.

For investors, the charge carries no operational weight and does not reflect any outflow of cash. But it will inflate the reported cost base, making the underlying performance harder to read at first glance.

Complicating the picture further, revenue that had been expected in the first half of 2026 has slipped into the second half, owing to customer scheduling decisions and delays in US budget approvals. That timing shift, combined with the accounting charge, means today's numbers will require careful interpretation. The market will be listening for whether management maintains its full-year revenue guidance despite the delayed recognition.

Capital Infusion and an AI Optics Program

Ahead of the report, the company has taken steps to bolster its balance sheet. Bootstrap Europe IV SCSp exercised all of its warrants, subscribing for 1,659,015 new ordinary shares at SEK 4.53 each, funneling roughly SEK 7.5 million into the company. The sum is modest but provides immediate liquidity as the quarter closes.

On the operational front, Sivers has unveiled a joint development program with SemiNex Corporation focused on next-generation indium phosphide light sources for AI data center connectivity. The initiative carries an initial value of approximately $3.4 million — a strategically meaningful step into a growth segment, even if the financial scale remains limited for now.

A Correction, a Short-Seller Subplot, and a Volatile Tape

The company also moved over the weekend to correct an erroneous report claiming CEO Vickram Vathulya had sold 1,233,761 shares on July 24. Official filings confirmed no such transaction ever occurred. The clarification carries particular weight given the recent scrutiny of insider activity and short-seller positioning in the stock.

Roughly three weeks ago, media reports flagged shifts in disclosed short positions: Arrowstreet Capital was said to have built a new position, while D. E. Shaw and later Citadel Securities reportedly exited theirs. The stock has moved about 3.0 percent since those reports surfaced, suggesting the matter has largely played out and will likely take a back seat to today's earnings.

The share price itself tells a story of intense volatility. In pre-market trading, the stock sat at EUR 3.35, nearly flat against yesterday's close, which itself marked a 3.3 percent gain to EUR 3.30. Over seven days, the shares are up 6.6 percent; over 30 days, the gain stretches to 29 percent. Yet the stock remains far below its 52-week high of EUR 10.23 set in early June, and trades roughly 21 percent under its 50-day average of EUR 4.19. The annualized 30-day volatility of 161 percent underscores just how jittery trading in this name remains.

For shareholders, the afternoon's report will need to demonstrate that the operational story — progress on programs like the SemiNex collaboration — can offset the distortion from the payroll tax charge, and clarify how management views the company's capital position following the warrant exercise.
