when is smci stock split date is a common investor query after Super Micro Computer’s rapid share price run and its corporate action in 2024. This article answers when is smci stock split date with official dates and explains the background, terms, mechanics, market effects, options adjustments, shareholder procedures, subsequent developments, and practical takeaways. Read on to quickly find the one-line factual summary and detailed context supported by company filings and major financial coverage.

Key factual summary (one-line answer)

The 10-for-1 SMCI stock split was announced in August 2024, became effective at 5:00 p.m. ET on September 30, 2024 (per the company’s SEC Form 8-K), and shares began trading on a split-adjusted basis at the market open on October 1, 2024.

Background

Super Micro Computer, Inc. (ticker: SMCI) is a U.S.-based supplier of server systems, high-performance computing solutions, and AI infrastructure components. As of reporting around the split, Super Micro’s business focus on server and AI hardware, combined with strong revenue and demand trends for AI accelerators, coincided with a substantial share price run-up in 2023–2024. That share price appreciation drove interest from retail and institutional investors and is the typical corporate backdrop that leads boards to consider a forward stock split to increase share affordability and broaden the investor base.

As of August 6, 2024, media coverage and investor commentary noted the rapid valuation change for SMCI shares following strong sales momentum tied to AI hardware demand. As of September 26, 2024, the company formalized split details in an SEC filing (Form 8-K) that set the effective time for the split; major outlets covered the announcement on August 6, 2024.

Announcement

The company publicly announced the stock split in early August 2024. As of August 6, 2024, CNBC reported the board’s approval of a 10-for-1 forward stock split and covered the company statement and investor reaction the same day. The formal legal disclosure and the final administrative details—such as the exact effective time and transfer agent instructions—were recorded in the company’s SEC Form 8-K filed later in September 2024.

Media coverage emphasized the size of the split (10-for-1) and the context of SMCI’s recent performance; however, press reports also noted that a stock split is a capital structure action that does not change underlying company fundamentals.

Terms of the stock split

Split ratio: 10-for-1 (forward split).
Type: forward stock split—each share outstanding before the split entitled its holder to receive nine additional shares so that every one pre-split share becomes ten post-split shares.
Ticker: remained SMCI (no ticker change reported).
CUSIP: a new CUSIP was disclosed in the SEC filing (new CUSIP 86800U302) identifying the post-split security for clearing and registration purposes.

The company executed the split by amending its certificate of incorporation (or other charter documentation) as required under corporate law and in line with board authorization. The SEC Form 8-K recorded these mechanics and the effective time for the amendment to take effect.

Key dates and timeline

Announcement date: August 6, 2024 — public announcement and press coverage reported the board’s decision to split the stock 10-for-1.
Effective time (legal record change): 5:00 p.m. ET on September 30, 2024 — per the company’s SEC Form 8-K filed September 26, 2024, the charter amendment effect time was scheduled for this timestamp.
Trading-adjusted date: October 1, 2024 (market open) — post-split shares began trading on a split-adjusted basis at the opening of trading following the effective time.
Certificate exchange / transfer agent deadlines: Computershare acted as the exchange agent; instructions for certificated holders and details for surrendered pre-split certificates were included in the company disclosures and transfer agent communications.

As of September 26, 2024, the SEC Form 8-K provided the definitive effective time and procedural instructions. Market participants typically note that the legal effective time is distinct from the moment exchanges show adjusted pricing; for SMCI the legal effective time (5:00 p.m. ET on Sept 30) meant the market open on October 1 reflected the 10-for-1 adjustment.

Mechanics and shareholder procedures

How a forward split is executed and how shareholders are served depends on whether shares are held in street name (brokerage account/book-entry) or in certificated form:

Amendment to charter: The split was effected by the board authorizing and filing the requisite amendment to the company’s certificate of incorporation. That amendment changes the total authorized shares and the par value mechanics (if applicable) for record-keeping.
Transfer agent role: The company engaged a transfer agent (Computershare acted as exchange agent for SMCI) to implement the exchange of pre-split shares and to process surrendered physical certificates. The transfer agent also provides information on timelines, required forms (e.g., a letter of transmittal for physical certificates), and mechanics for obtaining post-split certificates or book-entry credits.
Book-entry (street) holders: For most retail and institutional holders who hold shares in brokerage accounts, no action was typically required. Brokers receive instructions from the transfer agent and clearinghouses to update account balances so pre-split holdings are automatically updated to post-split quantities (ten times prior holdings) on the trading-adjusted date.
Certificated holders: Investors holding pre-split physical certificates must follow the transfer agent’s instructions, which commonly involve completing a transmittal form and surrendering their old certificates in exchange for new post-split certificates or book-entry credits. There is usually a timeframe and specific required documentation to complete this exchange. The company and transfer agent issue notice with explicit steps.
Fractional shares: When a split creates fractional share entitlements for some shareholders, companies typically instruct the transfer agent or brokers to either round up and issue cash-in-lieu payments or aggregate fractions and pay cash. The SEC Form 8-K and transfer agent notices detail how SMCI handled fractional entitlements in this split.

Options and other market microstructure effects

Derivatives on SMCI stock required adjustment so that contract holders would preserve the same economic exposure post-split:

Options adjustments: The Options Clearing Corporation (OCC) and exchange operators typically issue official adjustments to listed options to reflect a stock split. For a 10-for-1 forward split, standard single-share option contracts are usually modified so that each contract represents a larger number of underlying post-split shares (e.g., a 10-to-1 multiplier adjustment), and strike prices are divided by the split ratio to preserve the contract’s economic value.
Practical implications for option holders and brokers: Option holders should be aware that the number of shares deliverable under each contract and the strike price change. Brokers normally communicate these adjustments and handle the bookkeeping, but options traders should confirm contract terms and exercise/delivery considerations with their brokers.
Other derivatives and institutional arrangements: Warrants, restricted stock units (RSUs), employee stock purchase plans (ESPPs), and other equity-linked instruments were similarly adjusted as prescribed by governing contracts and the company’s equity plan rules.

Rationale for the split

Companies pursue forward stock splits for several typical reasons, which are relevant to SMCI’s decision:

Affordability: A high share price can make a single share less accessible to retail investors. Splitting shares lowers the per-share price without changing investor ownership percentage, potentially attracting a broader retail base.
Liquidity: Increasing the number of outstanding shares can increase float and intra-day tradability, which companies sometimes cite as a rationale.
Psychological and marketing effects: Stock splits often generate media attention and investor interest. Boards sometimes use splits to signal confidence in future prospects, though splits do not alter fundamental financial metrics.

Company statements and press coverage in August 2024 framed the 10-for-1 split as a corporate action intended to improve liquidity and broaden access for investors amid a period of strong share price appreciation tied to the company’s AI and server demand.

Market reaction and immediate price impact

When a split is announced, markets react to both the announcement and the company’s broader news environment. As of the announcement in early August 2024, press coverage noted notable intraday moves as investors digested the news. It is important to remember that a split is neutral with respect to company fundamentals: the number of shares increases while per-share price decreases proportionally, leaving market capitalization unchanged immediately due to the split alone.

Short-term price moves around the announcement often reflect investor sentiment, updated expectations about demand, and any concurrent corporate news rather than the split itself. Trading on the first day after a split is often volatile as electronic records are updated, some retail interest re-enters the stock, and options/derivatives adjustments propagate through markets.

Subsequent developments and context (post-split)

As of late 2024, several corporate governance and regulatory items drew investor attention for SMCI that helped shape post-split investor perceptions. The company disclosed various developments in SEC filings and press coverage that investors monitored around and after the split timeframe:

SEC Form 8-K disclosures: The company’s Form 8-K filed on September 26, 2024, formalized the effective time and the CUSIP for the split. That filing is the authoritative document for the split details.
Auditor and filings: Around the split period, there were disclosures and media attention on audit- and filings-related items that can include auditor changes, restatements, or delayed filings in other corporate cases. For SMCI, investors monitored any such notices and regulatory correspondence that could affect confidence or short-term price dynamics.
Exchange and regulatory notices: Nasdaq or other regulators can issue notices if corporate governance or filing issues arise. Any such regulatory communications were included in public filings and covered by financial press.
Media and market commentary: Coverage by outlets like CNBC, Yahoo Finance, Forbes/Motley Fool, and market data providers summarized the split and tracked subsequent trading activity and any company-specific developments.

All of these items influenced investor focus post-split. As of respective reporting dates (e.g., SEC filing dated September 26, 2024, and media reporting on August 6, 2024), readers should consult those primary sources for the official disclosures and current status.

Tax and accounting considerations

U.S. federal tax treatment: A typical forward stock split is generally a non-taxable corporate action for U.S. federal income tax purposes. The cost basis per share is adjusted proportionally so that the aggregate cost basis remains the same immediately after the split. Shareholders should track their adjusted per-share basis for future capital gain/loss calculations.
Accounting: From an accounting perspective, a forward split does not change total shareholders’ equity; it changes the number of outstanding shares and the par value per share if relevant. Companies disclose the split and provide details in SEC filings and public notices.
Professional advice: Tax outcomes can vary by jurisdiction and personal circumstances. Consult a tax professional for individualized advice—this article is informational and not tax advice.

Historical significance and related corporate actions

First recorded split: The 2024 10-for-1 split is notable in SMCI’s corporate history as a prominent forward split reflecting years of share price appreciation. Where applicable, companies often list split history in investor relations materials and SEC filings for shareholder reference.
Peer practices: Large technology and infrastructure suppliers occasionally pursue stock splits after multi-year share price gains to improve accessibility. This action is common among companies experiencing rapid valuation growth tied to secular demand drivers like AI infrastructure.

Practical checklist for shareholders

If you held or plan to hold SMCI around the split, here are practical steps and checks:

Check your account: If you hold shares in a brokerage account, expect that your holdings will be updated automatically to reflect ten times the pre-split share count on the trading-adjusted date (October 1, 2024). No action typically required for street-name holdings.
Certificated shares: If you hold physical stock certificates, review the transfer agent (Computershare) instructions and prepare to submit the required documents for exchange. Follow any letter of transmittal instructions and confirm whether you prefer a new physical certificate or book-entry credit.
Confirm fractional treatment: If fractional shares result from the split, check the procedures (cash-in-lieu rules or rounding policies) described in the transfer agent notice and broker communications.
Options and derivatives: If you hold options, check with your broker about contract adjustments and confirm the new contract specifications and the effect on strike prices and position sizing.
Records and tax basis: Retain documentation of holdings pre- and post-split so you can calculate adjusted cost basis for future tax events.
