Analysguiden maintains a justified value of SEK 0.95 for the auction platform Vaxxa. Net sales increased 57 percent to SEK 29.5 million in the second quarter and EBITDA turned to SEK 0.6 million.The analysis firm raises its short-term sales assumptions but slightly lowers its long-term margin assumptions, as margin expansion was limited despite the strong sales growth.Analysguiden assesses that Vaxxa stands stronger after the second quarter, but wants to see a more sustainable margin improvement, stable cash generation and clearer financial communication before the justified value is raised.
