The SEC has immediately suspended Nihat Cardak from appearing or practicing before the Commission following his federal securities-fraud conviction. Cardak served as Chief Financial Officer of GigaMedia Access Corporation from 2006 through 2019 and was later convicted in federal court of conspiracy to commit securities fraud. The September 22, 2026 SEC order does not relitigate the underlying criminal case. Instead, it applies Rule 102(e)(2), which provides for the suspension of individuals convicted of qualifying felonies or offenses involving moral turpitude. The proceeding shows how a criminal securities case can continue to produce professional consequences years after the original conduct, particularly for former finance executives whose work may involve SEC filings, accounting or regulatory submissions.

NEWS:
The SEC identifies Cardak as the former Chief Financial Officer of GigaMedia Access Corporation, a position he held from 2006 until 2019. According to the Commission's order, a judgment of conviction was entered against him on May 18, 2023 in the U.S. District Court for the Southern District of New York after he was found guilty of one count of conspiracy to commit securities fraud. The SEC subsequently initiated a Rule 102(e)(2) proceeding based on that criminal conviction rather than opening a new fraud case concerning separate 2026 conduct.
The timing is important. The SEC order states that the U.S. Court of Appeals for the Second Circuit acted on Cardak's criminal case on August 15, 2025. By September 2026, the Commission was therefore dealing with the professional-practice consequences of an already established criminal judgment. Rule 102(e) is particularly significant for accountants, attorneys, finance executives and other professionals whose work may involve financial statements or submissions presented to the SEC. A suspension under the rule can prevent an individual from appearing or practicing before the Commission even though the criminal prosecution itself occurred in a different federal forum.
The case also appears in the SEC's Accounting and Auditing Enforcement Release series as AAER No. 4601. That classification is useful for due-diligence purposes because it places Cardak's matter within the Commission's financial-reporting and professional-accountability record, rather than treating the suspension as a generic administrative notice. SEC records show that the agency continues to publish accounting and auditing enforcement actions involving executives, accountants and issuers whose conduct affects financial reporting or professional practice before the Commission.
WHY THIS CASE MATTERS:
The Cardak proceeding illustrates why an executive's regulatory history should not be reviewed only by searching for recent company-level SEC charges. Criminal convictions, appeals and later professional-practice orders can form separate layers of the same regulatory record. An individual may no longer work for the original issuer when the SEC imposes a professional suspension, but the later order can still be relevant when evaluating that person's ability to participate in future SEC-facing work.
For investors and compliance teams, the case also demonstrates the value of matching names across criminal court records, SEC administrative proceedings and Accounting and Auditing Enforcement Releases. A simple company-name search may miss later actions against former officers. Searching the executive's name together with the original issuer and AAER record provides a more complete picture of the regulatory timeline.
