Lead / Summary

Has Micron stock ever split? Yes. Micron Technology (MU) executed three stock splits during the 1990s and 2000: 19 April 1994 — 5-for-2, 23 May 1995 — 2-for-1, and 2 May 2000 — 2-for-1. The combined effect converted each pre‑1994 share into 10 shares after the last split.[1][2][3]

As of 2026-01-23, authoritative historical data providers (Macrotrends, CompaniesMarketCap) and Micron’s public filings corroborate these three split events.[2][1]

Stock split history (chronological)

Below are the official stock-split events recorded for Micron Technology in chronological order. Each item lists the split date, ratio, and the immediate mathematical effect on outstanding shares.

19 April 1994 — 5-for-2 (5:2)

On 19 April 1994 Micron declared and effected a 5-for-2 stock split. That ratio increased the number of outstanding shares by 2.5× (each 2 shares became 5).^1 The 5-for-2 split raised share counts immediately while dividing the per‑share price proportionally.[1]

23 May 1995 — 2-for-1 (2:1)

On 23 May 1995 Micron completed a 2-for-1 stock split. Under a 2-for-1 split every share held became two shares, doubling the outstanding share count and halving the per‑share price on the effective date.^2 This followed the 1994 split during a period of equity market appreciation and company growth.[2]

2 May 2000 — 2-for-1 (2:1)

On 2 May 2000 Micron executed another 2-for-1 split, the most recent split to date. Like prior 2-for-1 splits, this event doubled outstanding shares and halved the per‑share trading price on the effective date.[3]

Cumulative effect

Cumulatively, the 1994 (5:2), 1995 (2:1) and 2000 (2:1) splits mean a single Micron share held before 19 April 1994 would have become 10 shares by 2 May 2000 (1 × 2.5 × 2 × 2 = 10).[1][2][3]

Context and rationale for the splits

Stock splits are a corporate action used by many public companies for common business reasons: to make shares more affordable to retail investors, to increase liquidity and trading activity, and to broaden the shareholder base. Companies sometimes split their stock after strong price run-ups so that the per‑share price is more accessible to a wider set of investors.

Micron’s splits in the mid‑1990s and 2000 came during periods when semiconductor and tech stocks were experiencing strong investor interest and price appreciation. While companies do not change fundamental value via a split, management and boards commonly approve splits to support marketability of the shares and to align share price levels with comparable firms or investor expectations. Micron’s board and management likely weighed these standard considerations when authorizing the 1994–2000 splits.[1][2][3]

Effect on shareholders and on market values

Stock splits change the number of shares outstanding and the per‑share price but do not change the company’s total market capitalization (all else equal). A split is essentially a re-denomination of shares.

Example (simple math):

• If you held 1 share before 19 April 1994, after the three splits you would hold 10 shares. The per‑share price would be adjusted down by the same cumulative factor (10× fewer dollars per share) so the market value of your holding remains proportionally the same immediately after each split, ignoring market moves.[1][2][3]

Effects investors commonly see:

• No automatic change in proportional ownership. Percentage ownership of the company is preserved after a split because all outstanding shares increase by the same ratio.
• Cost basis and tax attributes are adjusted on a per‑share basis. The total cost basis for your holding does not change, but your cost per share is reduced proportionally to the split ratio for tax reporting purposes.
• Liquidity and share counts increase, often enabling more granular trading sizes (smaller lots) for retail investors. However, splits do not guarantee future price gains or losses.

All descriptive examples above are consistent with Micron’s three historical splits.[1][2][3]

Adjustments to historical prices, dividends and indices

Data providers and exchanges routinely adjust historical price series and dividend records to reflect stock splits. This ensures continuity when plotting historical charts or calculating historical returns. After a split, charts show split‑adjusted prices so that trend lines and percentage returns are comparable over time.

Common sources that provide split‑adjusted histories for Micron (MU) include large market data sites and historical databases. These services apply the 1994, 1995 and 2000 split ratios retroactively so pre‑1994 prices are shown on a per‑share, split‑adjusted basis relative to today’s share counts.[1][2][3]

When reviewing dividend histories, total return calculations and index weightings, always confirm whether the data are split‑adjusted. Indices that include Micron also use split‑adjusted share counts and prices when calculating market capitalization and index weights.

Authorization process and corporate disclosure

Stock splits are corporate actions typically authorized by the company’s board of directors—often after a recommendation from management. Material details (split ratio, record date, and effective/ex‑split date) are disclosed via corporate press releases and required filings with securities regulators and the exchange. For U.S. public companies like Micron, formal disclosure frequently appears in SEC filings (8‑K or proxy materials) and in press releases or exchange notices.[1][2][3]

Micron’s board authorized the splits that took effect in 1994, 1995 and 2000, and those events were publicly announced. As of the latest official records through 2026‑01‑23, Micron has not announced any further stock splits since the 2000 event.[1][2][3]

Comparison with industry peers

Semiconductor and broader technology firms have historically used stock splits with varying frequency. Some peers in technology split multiple times during long bull markets (notable examples in the tech sector have included companies that split repeatedly during periods of rapid growth), while others did not split at all or chose share‑buybacks or other capital management strategies instead.

Micron’s three splits through 2000 position it among those tech firms that used splits during 1990s market cycles to maintain accessible share prices, though other companies in the sector either split more often or adopted different capital actions. The decision to split depends on company strategy, share price level and board preferences rather than on industry rules.

Potential for future splits

Whether Micron will split its stock again depends on several practical factors: current and expected share price level, the preferences of management and the board, market conditions and investor relations goals. Companies typically consider splits when a high per‑share price might deter participation from certain retail investors or when they want to increase liquidity.

As of 2026‑01‑23 there has been no public announcement from Micron’s board about an upcoming split. Any future split would be announced by the company with details on ratio, record and effective dates through official filings and press releases.[1][2][3]

How to verify split history (primary sources)

To confirm Micron’s split history yourself, prioritize primary sources and official records:

• Company SEC filings: 8‑K reports, proxy statements, and annual reports often record corporate actions such as splits. For U.S.-listed firms, EDGAR filings are the authoritative archival record.[1]
• Micron corporate press releases and investor relations bulletins: the company’s own IR materials and press releases document split declarations and ex‑split dates.[1]
• Exchange notices: stock exchanges publish corporate action notices when splits affect trading and share counts.

• CompaniesMarketCap — Micron Technology stock split history (dates and ratios).[1]
