Understanding SemiLEDs Corporation's SEC Filings

Form 4 — Insider Transactions

Executives, directors, and large shareholders must report any purchase or sale of LEDS shares within two business days. Consistent buying by multiple insiders is often read as a confidence signal; large sales may reflect diversification or liquidity needs rather than negative conviction.

Form 144 — Proposed Insider Sales

Filed when a company affiliate intends to sell restricted or control shares. A Form 144 is a notice of intent, not confirmation — the actual sale is later confirmed via Form 4. It gives investors advance visibility into planned insider selling activity.

8-K — Material Events

The 8-K is an event-driven filing that SemiLEDs Corporation must submit within four business days of a significant development — including earnings results, mergers, executive changes, credit facility updates, or regulatory actions. Each 8-K item code maps to a specific event type.

10-Q & 10-K — Periodic Reports

The 10-Q (quarterly) and 10-K (annual) are comprehensive reports covering SemiLEDs Corporation's financial results, risk factors, management discussion, and business operations. The 10-K includes audited financials and is the most complete public disclosure the company makes each year.

Frequently Asked Questions — LEDS SEC Filings

What SEC filings does SemiLEDs Corporation submit to the SEC?

SemiLEDs Corporation (LEDS) submits several types of SEC filings including Form 4 (insider transactions), Form 144 (proposed insider sales), 8-K reports (material events such as earnings releases, acquisitions, leadership changes), and periodic reports — the 10-Q (quarterly) and 10-K (annual). All filings are publicly available through SEC EDGAR.

What does a Form 4 filing tell me about LEDS?

A Form 4 for LEDS discloses a transaction by a company insider — typically a director, officer, or 10%+ shareholder. It shows the date, number of shares bought or sold, the price, and the insider's updated total ownership. Consistent insider buying across multiple executives is often interpreted as a bullish signal.

How do I interpret an 8-K filing from SemiLEDs Corporation?

An 8-K signals a material event requiring prompt disclosure. Common triggers include earnings pre-announcements, acquisitions, leadership appointments or departures, credit changes, or regulatory actions. Read the item codes inside the filing to understand exactly what was disclosed before drawing conclusions.

What is the difference between a 10-K and 10-Q for LEDS?

The 10-K is SemiLEDs Corporation's annual report with fully audited financial statements, comprehensive MD&A, and complete risk factor disclosures — filed 60–90 days after fiscal year-end. The 10-Q is a lighter quarterly report with unaudited financials filed for the first three quarters. Together they provide a continuous financial picture of the company.

Where can I see all LEDS SEC filings directly on EDGAR?

You can view all historical SemiLEDs Corporation filings on the SEC EDGAR company page for LEDS. Each filing card on this page links directly to the original SEC document.

How often does SemiLEDs Corporation file with the SEC?

SemiLEDs Corporation files one 10-K per year and up to three 10-Qs per year. Form 4 insider transactions must be reported within two business days of each trade, so the frequency depends on how often insiders are buying or selling LEDS shares. 8-K filings occur whenever a material event happens — which can be several times per quarter for an active company.
