National Instrs Stock Price, News & Analysis

NATI historically represented National Instruments Corporation, commonly known as NI, on the Nasdaq stock market. According to company and transaction announcements, NI was a publicly traded producer of software-connected automated test and measurement systems and related technologies. The company focused on helping engineers and enterprises address complex engineering and validation challenges through data, automation, and software-centric test systems. As disclosed in an acquisition announcement, NI’s common stock has ceased trading on Nasdaq following its acquisition by Emerson.

NI operated in the electromedical and electrotherapeutic apparatus manufacturing industry within the broader manufacturing sector. The company described itself as an industry leader in automated wireless test and measurement and as a provider of software-connected automated test and measurement systems. Its offerings combined hardware, software, and data analytics to support research, validation, and production test workflows across multiple end markets, including semiconductor, electronics, transportation, aerospace, defense, and energy-related applications, as reflected in various product and partnership announcements.

Business focus and solutions

Based on NI’s own descriptions, the company centered its business on software-connected test and measurement systems. It highlighted a portfolio that included:

• Automated wireless test and measurement systems used for RF and wireless product validation and production test.
• Semiconductor test analytics platforms, such as NI Global Operations (GO, formerly Optimal+), designed to provide analytics and control across semiconductor test operations.
• High-power test systems for battery testing and simulation, such as the NHR 4800 high-density battery cycler and emulator, positioned for electric vehicle, aerospace, and energy applications.
• PXI-based instruments, including the third generation PXI Vector Signal Transceiver (PXIe-5842), aimed at high-performance RF measurements for aerospace, defense, and wireless products.
• Software products such as LabVIEW, described as a long-standing product for data acquisition, instrument control, and automation.

NI emphasized a software-centric approach to test, where hardware platforms are tightly integrated with software and analytics to enable engineers to use test data and insights to influence both product and business performance. Announcements about LabVIEW upgrades and analytics platforms underscore NI’s focus on enabling users to work with test data, automate workflows, and implement real-time or near real-time analytics in demanding environments such as semiconductor test floors.

Industry role and applications

NI’s products and platforms were used in a range of technology-intensive industries. Press releases describe applications including:

• Semiconductor test operations, where the NI Global Operations platform and its real-time application enablement layer are used to run analytics models in-line with test execution on automated test equipment (ATE).
• Next-generation RF and wireless systems, where the PXIe-5842 Vector Signal Transceiver supports spectrum analysis, signal analysis, signal generation, and testing of technologies such as radar, SatCom, electronic warfare systems, and commercial wireless standards.
• Battery testing and simulation for electric vehicles, aerospace, and energy storage, where the NHR 4800 battery cycler and emulator supports research, validation, production, and second-life battery applications.
• Data acquisition, instrument control, and automation tasks across many engineering domains through LabVIEW and related software tools.

In addition, NI’s software defined radios and other equipment appear in research testbeds such as the ARA rural wireless testbed within the Platforms for Advanced Wireless Research (PAWR) program, where NI radios are deployed as part of mid-band connectivity in a multi-vendor research environment. This highlights NI’s presence in advanced wireless research and experimentation infrastructure.

Acquisition by Emerson and corporate status

A transaction announcement from Emerson states that Emerson completed its acquisition of NI at an equity value of $8.2 billion. Following the closing of this transaction, NI became a new reported segment within Emerson called Test & Measurement, consolidated into Emerson’s Software and Control group. The same announcement notes that, as a result of the transaction’s closing, NI’s common stock has ceased trading on the Nasdaq. This indicates that NATI, as a ticker symbol, now represents a former listing rather than an actively traded independent public company.

Within Emerson, the Test & Measurement business continues to be headquartered in Austin, Texas, according to the acquisition announcement. NI’s operations, customer relationships, and technology portfolio are described as contributing to Emerson’s broader automation strategy and expanding Emerson’s exposure to discrete and industrial software markets.

Historical operating profile

Prior to the acquisition, NI reported financial results as an independent public company. A second-quarter earnings release describes NI’s net sales as consisting of product revenue and software maintenance revenue, and refers to the company’s focus on high-growth subsegments and global execution. The same release notes that NI generated revenue across regions including the Americas, APAC, and EMEA, and that it managed a backlog and supply chain constraints as part of its operations. While specific figures in that release are time-bound, they illustrate NI’s role as a sizable participant in the test and measurement market with global operations.

Earlier descriptive material notes that NI has been active since 1976 and headquartered in Austin, Texas, and that it has served tens of thousands of customers across many industries. That historical description also refers to an integrated hardware and software platform and a broad customer base, reinforcing NI’s long-standing presence in engineering and scientific test and measurement.

Key technologies and platforms highlighted in recent materials

• NI Global Operations (GO): A semiconductor analytics platform (formerly Optimal+) that supports real-time analytics at the edge when integrated with ATE vendors. A real-time application enablement layer allows analytics models to run in-line with test execution on secure, low-latency tester servers.
• PXIe-5842 Vector Signal Transceiver: A third generation PXI VST that combines RF signal generation and analysis with extended frequency coverage and bandwidth, designed to support demanding RF test scenarios in aerospace, defense, and next-generation wireless applications.
• NHR 4800 battery cycler and emulator: A high-density, modular, and scalable battery test system capable of acting as a battery cycler, DC source, DC load, battery emulator, and amplifier for power-level hardware-in-the-loop testing, aimed at low to mid-range battery modules and packs, fuel cells, energy storage systems, and solar PV systems.
• LabVIEW: NI’s long-standing software product for data acquisition, instrument control, and automation, with recent updates focused on usability enhancements such as zoom for block diagrams, quick change for faster object creation, and improved build performance, as well as collaborations to improve package-related workflows.

How investors and researchers can use NATI information today

Because NI has been acquired by Emerson and NI’s common stock no longer trades on Nasdaq, NATI is best understood as a historical ticker. Information associated with NATI can still be useful for:

• Reviewing NI’s historical financial performance, business model, and product evolution prior to its integration into Emerson.
• Analyzing the rationale and impact of Emerson’s acquisition of NI within the automation and test and measurement markets.
• Understanding the legacy NI product and software platforms that now form Emerson’s Test & Measurement segment.

For current operational and financial information, users would refer to Emerson’s disclosures and segment reporting that include the Test & Measurement business built around NI’s former operations.
