MU vs TER: which business are you actually underwriting?
Micron Technology (MU) is the larger business by reported revenue: $37.4B in its fiscal year ended Aug 2025, about 12× TER's $3.2B (fiscal year ended Dec 2025). MU's net margin was 22.8% and TER's 17.4%. The SEC classifies them differently (Semiconductors & Related Devices; Instruments For Meas & Testing of Electricity & Elec Signals); what connects them is shared exposure to the Artificial intelligence and Tariffs & trade research themes, not a common industry.

MU vs TER: audited financials
- Scale: MU's $37.4B of revenue is about 12× TER's $3.2B.
- Net margin: MU kept 22.8% of revenue as net income versus 17.4% at TER.
- Cash conversion: operating cash flow equalled MU 46.9% of revenue, or 2.05× net income; TER 21.1% of revenue, or 1.22× net income. A ratio well above 1× usually reflects non-cash charges or working-capital release; well below 1× can reflect working-capital build or non-cash gains.
- Periods: the fiscal years end about 4 months apart (2025-08-28 for MU, 2025-12-31 for TER), so each figure reflects somewhat different demand and cost conditions.

What moves each company
Company-specific drivers maintained by Yield Theory. Use them to decide which filing deserves deeper work; they are not predictions.
What moves MU
- DRAM pricing and bit supply, which account for most of Micron's revenue
- High-bandwidth memory (HBM) qualification and share at AI accelerator customers
- NAND pricing and data-center SSD demand
- Capital expenditure and the timing of new fab capacity
What moves TER
We have not yet published a company-specific driver list for TER. The primary source is Item 1 (Business) and Item 1A (Risk Factors) of its 10-K filed 2026-02-19.
The investment question
You now know MU reports about 12× TER's revenue, and MU keeps more of each dollar as net income. Those are the facts. The investment question is what each share price already assumes about their exposure to artificial intelligence and tariffs & trade, including “DRAM pricing and bit supply, which account for most of Micron's revenue” at MU, and which evidence in the next filings would prove that assumption wrong.

Start with primary filings because fiscal calendars and accounting presentation can make superficially similar quarters incomparable. MU's fiscal year ends September 3, while TER's ends December 31. Normalize the reporting periods before comparing growth, margins, capital intensity, or guidance.
The current verified House and Senate snapshot contains 31 matched transaction rows for MU and 9 matched transaction rows for TER. These delayed, range-based disclosures can identify a filing to inspect; they do not establish motive, conviction, or a real-time trading signal.

What this comparison cannot tell you
This page does not contain licensed live prices, a valuation model, earnings estimates, portfolio constraints, or a forecast of future returns. SEC classifications can be broad, company descriptions can lag strategic change, and the latest annual filing may predate a material acquisition or divestiture. Read subsequent quarterly and current reports before making a decision.
A stronger business is not automatically the better stock. Starting valuation, expectations, capital structure, cyclicality, dilution, and the probability of each thesis determine the investment outcome. Use this comparison to frame the work, then verify the numbers in the linked filings and current company disclosures.
MU vs TER FAQs
Are MU and TER direct competitors?
Not necessarily. Micron Technology files as Semiconductors & Related Devices and Teradyne as Instruments For Meas & Testing of Electricity & Elec Signals. The pair is compared because both map to the Artificial intelligence and Tariffs & trade research themes, not because the filings show head-to-head competition.
Is MU or TER the bigger company by revenue?
Micron Technology (MU) is the larger business by reported revenue: $37.4B in its fiscal year ended Aug 2025, about 12× TER's $3.2B (fiscal year ended Dec 2025). MU's net margin was 22.8% and TER's 17.4%. The SEC classifies them differently (Semiconductors & Related Devices; Instruments For Meas & Testing of Electricity & Elec Signals); what connects them is shared exposure to the Artificial intelligence and Tariffs & trade research themes, not a common industry. Each figure is the annual amount tagged in the company's own SEC XBRL filing; market value depends on live prices, which this page does not publish.
Which is better, MU or TER?
There is no context-free winner. Compare the operating exposures, filing evidence, valuation, balance sheet, and risks against the specific thesis you are testing. This page deliberately does not turn a static profile into a buy or sell recommendation.

No. Yield Theory does not republish unlicensed real-time market data. The financial figures on this page are the audited annual numbers Micron Technology, Inc. and Teradyne, Inc. tagged in their SEC XBRL filings.
