Deswell Announces First Half 2027 Results

Company Announces First Half Cash Dividend of $0.10 Per Share -

FOR IMMEDIATE RELEASE

MACAO (November 12, 2026) - Deswell Industries, Inc. (Nasdaq: DSWL) today announced its unaudited financial results for the first six months of fiscal 2027, ended September 30, 2026.

Net sales for the six months ended September 30, 2026 were $33.0 million, a slightly decrease of 0.6% compared to net sales of $33.2 million for the six months ended September 30, 2025. Net sales increased by 17.7% to $5.9 million in the plastic segment and decreased by 3.9% to $27.2 million in the Company’s electronic segment. 

Total gross margin was 19.8% of net sales during the six months ended September 30, 2026, as compared to 23.4% for the corresponding period of last year.  Gross margin in the plastic segment decreased to 12.9% of net sales in the segment for the first half of fiscal 2027, compared to 18.3% 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 decreased due to the appreciation of the Renminbi, increased labor costs resulting from the raise in minimum wage and social insurance costs in the first six months of fiscal 2027. Gross profit margin in the electronic segment decreased to 21.3% compared to 24.3% of net sales in the segment for the first half of last fiscal year. This was mainly due to the appreciation of the Renminbi, increased labor costs resulting from the raise in minimum wage and social insurance costs for the first six months of fiscal 2027. Operating income in the first half of fiscal 2027 was $0.9 million, compared to operating income of $2.5 million for the same period of fiscal 2026.

The Company reported net income of $5.0 million for the six months ended September 30, 2026, compared to net income of $7.5 million for the six months ended September 30, 2025. This was primarily due to a decrease in total gross margin and non-operating income for the six months ended September 30, 2026, as compared to the same period of fiscal 2026. Deswell reported basic and diluted income per share of $0.31 for the first half of fiscal 2027 (based on 15,885,000 weighted average shares outstanding), as compared to basic and diluted income per share of $0.47 for the first half of fiscal 2026 (based on 15,935,000 weighted average shares outstanding).

The Company's financial position remained strong, with $22.4 million in cash and cash equivalents and working capital totaling $87.0 million as of September 30, 2026. Furthermore, the Company has no long-term or short-term borrowings as of September 30, 2026.

Mr. Edward So, Chief Executive Officer, commented, “Revenue largely held steady in the first half of fiscal 2027 despite cautious end-market spending and subdued customer demand, reflecting the strength of our long-standing customer relationships. Supply chain volatility pushed back the timing of new product introductions, as extended component lead times and limited parts availability affected launch schedules. At the same time, Renminbi appreciation raised our operating and locally sourced material costs, with mandated minimum wage increases adding to labor costs.

“Our focus is on what we can control. We’re prioritizing operational efficiency, renegotiating supplier terms, and making selective investments in automation to protect margins while positioning ourselves for growth when customer demand improves. With a strong balance sheet, a solid cash position and no debt, we believe Deswell is well positioned to navigate the current economic environment to further drive shareholder value.”

First Half Dividend

The Company also announced that its Board of Directors today declared a cash dividend of $0.10 per share for the first six months of fiscal 2027. The dividend will be payable on December 23, 2026 to shareholders of record as of December 2, 2026.

Forward-Looking Statements

Statements in this press release that are "forward-looking statements" are based on current expectations and assumptions that are subject to risks and uncertainties. For example, our statements regarding our expected growth in sales from the electronic division in the coming year and our efforts to reduce overhead costs in our plastic division are forward-looking statements.  Actual results could differ materially because of the following factors, among others, which may cause revenues and income to fall short of anticipated levels or our overhead expenses to increase: our dependence on a few major customers; vigorous competition forcing product price reductions or discounts; the timing and amount of significant orders from our relatively few significant customers; continuing increases in resin prices that cannot be passed on to customers; unexpected production delays; obsolete inventory or product returns; losses resulting from fraudulent activity of our customers or employees; labor shortages that increase labor and costs; changes in the mix of products we manufacture and sell; adverse currency fluctuations in the Renminbi and Hong Kong dollar when translated to US dollars; potential new accounting pronouncements; and the effects of travel restrictions and quarantines associated with major health problems, such as the Severe Acute Respiratory Syndrome, on general economic activity.

For further information regarding risks and uncertainties associated with the Company’s business, please refer to the “Risk Factors” section of Company’s Annual Report on Form 20-F, copies of which may be obtained from the Website maintained by the Securities and Exchange Commission at http://www.sec.gov.

All information in this release is made as of the date of this press release.  Deswell undertakes no duty to update any forward-looking statement to conform the statement to actual results or changes in Deswell’s expectations.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(U.S. dollars in thousands except per share data)

In the opinion of Management, the accompanying unaudited financial statements contain all adjustments (all of which are normal and recurring in nature) necessary to fairly present the financial position of Deswell Industries, Inc. (the Company) at September 30, 2026 and March 31, 2026, the results of operations for the six months ended September 30, 2026 and September 30, 2025, and the cash flows for the six months ended September 30, 2026 and September 30, 2025.  The notes in the Consolidated Financial Statements contained in the Form 20-F Annual Report filed on July 30, 2026 under the Securities Exchange Act of 1934 should be read in conjunction with these Consolidated Financial Statements.

Marketable securities and other securities investments include debt and equity securities of which the aggregate fair value, unrealized gain and cost are as follows:

Marketable Securities

The Company acquired equity securities mainly listed on the Hong Kong Stock Exchange and the New York Stock Exchange. These securities are recorded at fair value based on quoted market prices.

Unrealized gain from these marketable securities for the six months ended September 30, 2026 is included in the non-operating income of the consolidated statement of income.

During the first half of fiscal 2027, realized loss from the sale of marketable securities was $7.

The basic net income per share and diluted net income per share are computed in accordance with ASC No. 260, "Earnings Per Share" (formerly the SFAS No.128 “Earnings Per Share”).

The basic net income per share is computed by dividing income available to common holders by the weighted average number of common shares outstanding during the period.  Diluted net income per share gives effect to all potentially dilutive common shares outstanding during the period.  

The weighted average number of common shares outstanding is adjusted to include the number of additional common shares that would have been outstanding if the potentially dilutive common shares had been issued.  In computing the dilutive effect of potential common shares, the average stock price for the period is used in determining the number of treasury shares assumed to be purchased with the proceeds from the exercise of options.

The net income for the six months ended September 30, 2026 and 2025 were both from the Company’s continuing operations.
