Sivers Semiconductors: A Tax Quirk Born From a 490% Rally Clouds Thursday's Q2 Report

Sivers Q2 faces SEK 42.9M non-cash tax charge and revenue delays; watch underlying AI optics growth amid insider buys and sells.

When a stock rallies roughly 490 percent in a single quarter, the celebration usually shows up in the shareholder letter. For Sivers Semiconductors, it is showing up in the tax line instead — and that is the headline investors need to keep in mind when the Swedish chipmaker delivers its second-quarter numbers on Thursday at 6 pm CET, followed by a webcast an hour later.

The company has already flagged a non-cash social security charge of SEK 42.9 million tied to the revaluation of employee equity programs. The trigger was regulatory: because the shares climbed from SEK 10.71 to SEK 63.15 during the period, the payroll tax liability on those schemes had to be marked higher. It is a paper hit, not a cash drain, but it will distort the income statement all the same.

Nor is that the only distortion. Sivers has confirmed that some revenue originally expected in the first half will now be booked in the second, owing to rescheduled customer projects and delays in US budget approvals. Taken together, the two effects argue for reading Thursday's print through the lens of the underlying business rather than the headline numbers.

Insider Moves Tell Two Stories

The run-up to the report has featured conspicuously divergent behaviour from the top of the company. CEO Vickram Vathulya bought 70,000 shares — a purchase only made possible after lock-up agreements expired on 16 July. Chairman Bami Bastani, by contrast, sold 275,000 shares and donated a further 60,000 to charity. The pattern resists easy interpretation: one insider adding exposure while another trims a position days before a scheduled earnings release is hardly a unified signal, though it does suggest the two men are operating from different playbooks.

In a related shift, Sivers has decided that all future quarterly reports and webcasts will land after market close, a change the company attributes to its increasingly international, US-heavy shareholder base. Thursday's 6 pm CET slot is the first test of that new rhythm.

Capital Infusion and a Long-Range AI Optics Bet

On the financing side, lender Bootstrap Europe IV SCSp exercised all of its warrants, subscribing for 1,659,015 new ordinary shares at SEK 4.53 apiece. That injection of roughly SEK 7.5 million lifts the total share and vote count to 356,740,332 from 355,081,317 — modest in size, but a useful top-up for a company simultaneously funding growth programmes.

The strategic focus remains optical interconnects for data centres. A joint development programme with SemiNex Corporation, valued at $3.4 million, is targeting next-generation indium phosphide light sources for AI clusters, with customer samples and initial production runs pencilled in for the second half of 2027. The company has also been identified as a supplier to Ayar Labs, which counts Nvidia and AMD Ventures among its backers — a validation of the broader co-packaged optics trend that Sivers is riding.

A Stock That Moves Fast — Both Ways

The market's mood has swung sharply in recent sessions. Tuesday brought a bounce of 8.6 percent to EUR 3.16, recovering from Monday's 13 percent slide to EUR 2.93. Over seven trading days the stock is still down 4.2 percent, though it remains 13 percent higher on a monthly basis. The 50-day average sits at roughly EUR 4.30, leaving the shares about 26 percent below that mark, and the 30-day annualised volatility of around 166 percent tells its own story about the trading environment.

Unconfirmed reports in Swedish media have suggested a major shareholder may have disposed of stakes without proper disclosure, though no substantiating detail has emerged. For now, Thursday's report is the event that matters — the moment when investors can weigh the accounting noise, the capital moves and the AI optics pipeline against one another and decide what Sivers is actually worth.
