The SEC has instituted an administrative proceeding against Gresham Worldwide, Inc., formerly known as Giga-tronics Incorporated, after the defense-electronics company stopped filing required periodic reports during a period of rapid corporate disruption. Gresham changed its name from Giga-tronics in March 2024, entered into a merger agreement with Ault Disruptive Technologies Corporation in June, and then filed for Chapter 11 bankruptcy protection in August 2024. The proposed merger was terminated almost immediately after the bankruptcy filing. According to the SEC, Gresham has filed no periodic report since its Form 10-Q for the quarter ended March 31, 2024, while unsolicited quotations for its common stock continue on OTC Link ATS under symbol GIGAQ. The September 2026 Section 12(j) proceeding therefore sits at the end of a broader sequence involving rebranding, financial distress, a failed transaction and bankruptcy.

NEWS:
The SEC's September 15, 2026 order identifies Gresham Worldwide as a California corporation located in Scottsdale, Arizona, with SEC CIK No. 719274. The company has a class of securities registered under Exchange Act Section 12(g), but the Commission alleges that it has not filed any periodic report since its Form 10-Q for the quarter ended March 31, 2024. Unsolicited quotations for Gresham common stock continue to be submitted on OTC Link ATS under symbol GIGAQ, creating a situation in which market visibility persists even though the company's formal periodic disclosure record has stopped.
The timing of the reporting gap is significant because Gresham underwent several major corporate changes almost simultaneously. On March 1, 2024, Giga-tronics Incorporated formally changed its corporate name to Gresham Worldwide, Inc. SEC filings show that the underlying business included purpose-built electronics, automated test systems, power electronics, radio and microwave products, with a focus on defense and healthcare markets. At the time of its March 2024 quarter, Gresham was also a majority-owned subsidiary of Ault Alliance and operated through multiple subsidiaries, including businesses in the United States, United Kingdom and Israel.
Only a few months after the name change, Gresham entered into a merger agreement with Ault Disruptive Technologies Corporation. The June 23, 2024 agreement contemplated Gresham becoming a wholly owned subsidiary of the acquirer following a merger with ADRT Merger Sub. That transaction did not reach completion. On August 14, Gresham filed a Chapter 11 reorganization petition, and the following day Ault Disruptive Technologies notified the company that it was terminating the merger agreement, citing the bankruptcy-related action as a terminating company breach under the agreement.
Financial warning signs were already visible in the company's final Form 10-Q. Gresham disclosed that its financial statements had been prepared on a going-concern basis while acknowledging recurring net losses and that operations had not generated sufficient cash flows. That disclosure is important when viewed against what happened next: within months the company entered Chapter 11, the merger collapsed, and normal periodic reporting stopped. The SEC's 2026 proceeding therefore concerns a filing failure that occurred against a documented backdrop of liquidity stress rather than in isolation.
The Commission has now instituted proceedings under Exchange Act Section 12(j), which can ultimately result in suspension or revocation of a registered class of securities when an issuer repeatedly fails to meet federal reporting requirements. The September 15 order begins that administrative process and is not itself a final revocation. Gresham remains listed on the SEC's delinquent-filings docket.
WHY THIS CASE MATTERS:
Gresham provides a useful example of why investors should reconstruct corporate events chronologically rather than treating an SEC delinquent-filing order as a standalone event. The company did not simply stop filing while operating normally. It changed names, disclosed going-concern concerns, agreed to a merger, entered Chapter 11 and lost that merger before its reporting record went stale. Each event materially changed what investors needed to know about the company.
The Giga-tronics-to-Gresham name change also creates a search and identity problem. Older filings, market references and historical business records may appear under Giga-tronics, while later bankruptcy and SEC records appear under Gresham Worldwide. Matching the common CIK No. 719274 and former-name disclosure is therefore essential for building the complete regulatory history rather than treating the names as separate companies.
The continued GIGAQ OTC quotations add another due-diligence issue. A ticker can remain visible after severe restructuring or bankruptcy, but the existence of that quotation does not mean investors have current audited financial information. In this case, the latest periodic financial statements predate the Chapter 11 filing and merger termination—two events that could materially alter assets, liabilities, ownership and going-concern assumptions.
