Sivers Semiconductors: Insider Moves and a SEK 42.9 Million Accounting Quirk Set the Stage for Thursday's Report

Sivers Q2 faces non-cash tax charge from stock surge, insider buys and sells, and warrant exercise. Report due Thursday after market close.

The days leading up to Sivers Semiconductors' second-quarter report have been anything but quiet. Between insider transactions that tell conflicting stories, a warrant exercise that bolsters the balance sheet, and a non-cash charge stemming from the stock's own spectacular rally, investors have plenty to digest before the Swedish chipmaker releases its numbers on Thursday evening.

A Tax Bill Born From a Share Price Surge

The most unusual item on the upcoming income statement has nothing to do with operations. Sivers has already flagged a non-cash payroll tax charge of SEK 42.9 million for the second quarter, triggered by the revaluation of social security liabilities linked to employee share programs. The culprit: a share price that rocketed from SEK 10.71 to SEK 63.15 during the period — a move that, under Swedish accounting rules, inflates the value of outstanding employee options and therefore the associated tax obligations.

The charge will weigh on reported earnings but represents no cash outflow. Management's commentary on this item, and on whether any similar effects could spill into the second half, is likely to be a focal point of Thursday's webcast presentation.

Insider Activity Points in Opposite Directions

Adding to the narrative, the company's leadership has been active in the market. Following the expiration of lock-up agreements on July 16, chairman Bami Bastani sold 275,000 shares and donated another 60,000 to charitable causes. In a contrasting move, CEO Vickram Vathulya acquired 70,000 shares — a purchase that signals confidence from the top even as the chairman trims his position.

The insider picture was briefly muddied by an erroneous report claiming Vathulya had sold 1.2 million shares. The company issued a correction stating that no such transaction had taken place, a reminder of how closely — and sometimes hastily — the market is scrutinizing every filing around this volatile stock.

Warrants Exercised, Questions on Ownership Structure

On the capital side, investor Bootstrap Europe IV SCSp has exercised all of its outstanding warrants, subscribing to 1,659,015 new ordinary shares at SEK 4.53 each. The exercise generated approximately SEK 7.5 million in gross proceeds for the company and lifts the total share count to 356,740,332, up from 355,081,317.

The dilution is modest, but ownership data suggests Bootstrap may have reduced a significant portion of its stake in a prior debt-to-equity conversion — without any filing indicating it crossed the five-percent notification threshold. That ambiguity adds another layer of uncertainty for investors tracking the shareholder register.

A Shift to After-Hours Reporting

Sivers has also announced a structural change: quarterly reports will now be published after market close as a matter of policy. The company cites its growing international shareholder base, particularly institutional investors in the United States, who stand to benefit from the time zone shift. The move signals a deliberate pivot toward a global investor audience rather than a purely Scandinavian one.

Thursday's report is scheduled for 18:00 CET, followed by a management presentation via webcast at 19:00 CET.

Revenue Timing and the SemiNex Partnership

Beyond the accounting noise, there is an operational story. Sivers has guided that some revenue originally expected in the first half will slip into the second half, owing to customer project scheduling and delayed budget approvals from the U.S. government.

The company's strategic momentum, meanwhile, rests partly on a joint development program with U.S.-based SemiNex Corporation. The initiative, valued at around $3.4 million, targets next-generation indium phosphide light sources for AI data centers — including high-power external laser sources, DFB arrays, and SOA amplifier stages. It underscores Sivers' positioning in the photonics market, where demand is being driven by the compute buildout for artificial intelligence.

The Trading Picture

The stock closed Tuesday at EUR 3.19, up 8.7 percent on the day, and has gained 14 percent over the past month. Still, it trades well below its 50-day average of EUR 4.30, and the annualized 30-day volatility of 166 percent speaks to the nervousness surrounding the name. On Wednesday, the shares were indicated higher, adding around 2.3 percent to trade near EUR 3.26.

Short seller activity has also been in flux: Arrowstreet Capital recently appeared as a new short position holder, while D. E. Shaw closed out its disclosed position. Since those filings, the stock has shed 5.4 percent — a reminder that sentiment can shift quickly in a stock with this kind of momentum and scrutiny.

With the warrant proceeds strengthening the balance sheet, a clearer picture of the payroll tax impact on the horizon, and the SemiNex collaboration advancing, Thursday's report will give investors their first consolidated look at how all these moving parts fit together.
