Seiko Epson reported first‑quarter business profit of ¥22.1 billion, representing a 12% increase over the same period last year. This profit exceeded the consensus analyst estimate of ¥20.7 billion and also surpassed the company’s internal target of approximately ¥19 billion. The quarter did not include any tariff‑refund income, a line item that some industry peers have recorded. Revenue from crystal devices reached ¥16 billion, showing a modest rise from the previous quarter and a 30% increase year‑on‑year. Within this segment, crystal oscillators used in optical transceivers contributed roughly ¥3 billion. The company also issued updated full‑year guidance that was higher than market expectations, with the revised outlook disclosed in its presentation materials.
