Castellum was trading at SEK 125.55 on Nasdaq Stockholm at 10:00 a.m. CEST on September 29, 2026, up 0.16 percent on the session. The share remains 8.56 percent below its 52-week high of SEK 137.30, while the market capitalization stood at SEK 56.9 billion.
Buyback changes the share structure
The central corporate event is Castellum's completed repurchase program. According to Placera on September 16, 2026, Castellum had repurchased 22,596,587 shares for a combined SEK 3.0 billion.
The repurchased stock represented 9.9 percent of registered shares, and Castellum held 47,040,587 treasury shares after the program. The scale matters because the company plans to ask shareholders to approve cancellation of 46,541,184 repurchased shares at an extraordinary meeting.
Analyst target stays above price
Goldman Sachs cut its Castellum price target to SEK 135 from SEK 145 and kept a Neutral rating on September 7, 2026, according to MarketScreener. The target is 7.53 percent above the intraday price of SEK 125.55, leaving the analyst view positive on valuation but cautious on the outlook.
Castellum's Q2 2026 revenue was SEK 2.42 billion, compared with SEK 2.403 billion in Q2 2025, while operating profit reached SEK 1.664 billion versus SEK 1.564 billion a year earlier, according to Affarsvärlden. Net income was SEK 634 million, up from SEK 189 million in Q2 2025.
October vote sets next checkpoint
