NATI stock reflects National Instruments’ delisting after Emerson takeover
Published on 09/20/2026 at 15:41 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
NATI stock (ISIN US63361B1026) represents the former listing of National Instruments on the New York Stock Exchange, but as of September 19, 2026 it is no longer traded independently following the company’s full integration into Emerson Electric after an acquisition.
National Instruments absorbed into Emerson Electric
According to Ad-hoc-news on September 19, 2026, National Instruments was fully acquired by Emerson Electric and the NATI stock has effectively been removed from regular trading, with the former National Instruments entity now operating within Emerson’s consolidated structure.
The same source states that National Instruments had been listed for many years as an independent test and measurement systems provider on the New York Stock Exchange before its acquisition, and that following the deal the NATI ticker ceased to trade separately while the assets and operations were folded into Emerson Electric’s larger industrial portfolio.
Implications for investors and key figures
As Ad-hoc-news explains, because NATI stock is no longer independently traded, today’s market assessment for former National Instruments shareholders largely depends on Emerson Electric’s consolidated performance metrics rather than a standalone NATI quote.
For investors, this means that historical NATI prices and trading ranges now serve mainly as background, while current investment decisions revolve around Emerson’s share price, earnings trends and cash flows, which collectively reflect the contribution of the National Instruments business alongside Emerson’s other segments.
NATI stock status after delisting
Per Ad-hoc-news, the NATI ticker historically referred to National Instruments shares traded on the NYSE, but after the acquisition the independent listing was discontinued and the security effectively functions only as a historical reference to the pre-merger company.
The same report notes that National Instruments historically operated in the test and measurement equipment sector and did not belong to major headline indices such as the S&P 500, with the present index context now determined by Emerson Electric’s listings and index memberships instead of the former NATI stock itself.
Stock price reference and investor perspective
Because NATI stock is no longer actively traded following the Emerson Electric takeover, there is no current, dated price, 52-week range or market capitalization specific to NATI as of September 20, 2026; investors instead rely on Emerson Electric’s quoted share price and market values, where the former National Instruments business is embedded in the broader industrial group.
