FOR IMMEDIATE RELEASE

MACAO (November 13, 2025) - Deswell Industries, Inc. (Nasdaq: DSWL)
today announced its unaudited financial results for the first six months of fiscal 2026, ended September 30, 2025.

Net sales for the six months ended September 30, 2025 were $33.2 million,
a decrease of 5.5% compared to net sales of $35.2 million for the six months ended September 30, 2024. Net sales decreased by 13.8% to
$5.0 million in the plastic segment and by 3.9% to $28.2 million in the Company’s electronic segment.

Total gross margin was 23.4% of net sales during the six months ended
September 30, 2025, as compared to 19.5% for the corresponding period of last year. Gross margin in the plastic segment decreased
slightly to 18.3% of net sales in the segment for the first half of fiscal 2026, compared to 19.5% of net sales in the segment for the
corresponding period of last fiscal year. As a percentage of sales, gross margin in the plastic segment slightly decreased due to an increase
in labor costs resulting from the raise in minimum hourly wage, offset by continued control in the consumption of raw materials in the
first six months of fiscal 2026
