** It expects 2026 EBITDA between 250 million euros and 255 million euros ($295 million-$301 million), versus a LSEG-compiled consensus mean of 268 million euros
** "EBITDA guidance ... is slightly disappointing and we flag low absolute numbers", J.P. Morgan says
** Despite the co being "notoriously cautious in guiding", the broker still expects a 1-2% cut to 2026 EBITDA consensus estimates
** The broker adds that "operational leverage is not fully coming through the system just yet as the company plans to further invest"
** Auto1 shares are at the bottom of STOXX 600 .STOXX European index
