Sivers Semiconductors Shifts to After-Hours Reporting as Investor Scrutiny Intensifies

Sivers moves earnings to post-market amid 15% drop, insider disclosure questions, and shifting short positions.

The Swedish chipmaker's decision to move its earnings releases to post-market hours is a quiet but telling adjustment — one that lands amid a stretch of turbulence that has left shareholders grappling with a 15% single-day drop, questions about insider disclosures, and a rotating cast of short sellers.

Sivers Semiconductors began publishing quarterly results after the close on August 20, with accompanying webcasts pushed back accordingly. Management frames the change as a bid to widen participation in investor presentations and court international shareholders, particularly those in the United States and Asia. For a European small-cap, the move is unusual — companies that adopt such timing typically do so to bridge time zones and let analysts across multiple regions dial in simultaneously.

It also arrives at a delicate moment. The stock closed Friday at EUR 2.44, then edged up 2.9% to EUR 2.51 on Monday — a modest rebound after a bruising stretch. Over the past seven sessions, the shares have shed 14%, and the monthly decline stands at 8.7%. A 50-day comparison is starker still: at current levels, the stock trades roughly 38% below its average of EUR 3.94.

A Disclosure Question Hangs Over the Register

Adding to the unease, the Swedish business daily Affärsvärlden reported on August 18 that a significant shareholder may have sold stock without proper disclosure. Such an omission, if confirmed, would carry particular weight for a company whose equity is already trading on nerves. The annualized 30-day volatility reading sits at 169% — a figure that underscores just how quickly sentiment can shift.

The short-selling landscape has been shifting in tandem. Arrowstreet Capital appeared as a newly disclosed short position on August 18, the same day D. E. Shaw dropped off the list. Two days later, Citadel Securities also exited the register of open short positions. The churn suggests institutional players are continually recalibrating their bearish bets rather than abandoning them outright.

The Tax Bill That Followed the Rally

Part of the current pressure traces back to a quirk of Sweden's payroll tax system. Following a sharp run-up in the share price, Sivers now faces a wage tax charge of SEK 42.9 million — an expense triggered by past gains that has landed squarely on the balance sheet.

The timing has been unkind. Roughly two weeks ago, the investor Bootstrap exercised all its warrants, subscribing to 1.6 million new common shares. Since that move, the stock has fallen about 36.3%. A separate milestone — the announcement of a development program with SemiNex for next-generation light sources aimed at AI data centers — has done little to steady the ship either; the shares are down 33.6% since that news broke just over three weeks ago.

A Waiting Game for the Fourth Quarter

For all the noise, the company's market capitalization still stands at roughly EUR 727 million, and management points to the fourth quarter of 2026 as the period when its growth strategy should begin to show tangible results. The technical picture offers little clarity: the relative strength index reads 37.2, which stops short of signaling extreme oversold conditions, yet the combination of unresolved ownership questions, shifting short positions, and a fragile news flow argues against any swift stabilization.

Whether the new reporting schedule genuinely broadens the investor base is a question that can only be answered at future earnings dates. For now, the market's focus remains on whether Sivers can translate its stated ambitions into operational delivery — and whether the transparency measures it is rolling out will be enough to rebuild confidence among institutional holders watching from the sidelines.
