The following are excerpts of the transcript of Emerson Electric Co.’s (“Emerson”) earnings call that was made available by Emerson on its website on February 8, 2023:

Surendralal L. Karsanbhai

President, Chief Executive Officer & Director

“Before I turn the call over to Frank, I wanted to briefly discuss our proposal to acquire National Instruments for $53 per share in cash. As you know, we made our offer public on January 17 and our correspondence with NI since 2022 May is available on maximizingvalueatni.com. Emerson is committed to an acquisition of NI and is participating in the strategic review process. We believe our premium all-cash proposal with no financing conditions or anticipated regulatory concerns is compelling and in the best interest of Emerson and NI shareholders.

We look forward to continued engagement with NI and its advisors and moving swiftly towards an agreed transaction. That said, the focus of this call is our performance for the quarter and we're not going to be commenting further on our proposal for NI at this time. Be assured that we'll continue to execute financial diligence as we review this opportunity.”

Stephen Tusa – JPMorgan Securities LLC:

“Right. Yeah. Just it does influence your cash, so just curious if you guys as the owners have a view on that. When it comes to NATI, how coveted is this asset for you guys? I mean, it doesn't seem like they're going to take anything below $60. Are you guys really willing to kind of go to the wall for this?”

Surendralal L. Karsanbhai:

“I can be very clear with you then we're not going to be the purchaser of the asset.”

Caution Concerning Forward-Looking Statements

This communication contains “forward-looking” statements as that term is defined in Section 27A of the Securities Act and Section 21E of the Exchange Act, as amended by the Private Securities Litigation Reform Act of 1995. All statements, other than historical facts, are forward-looking statements, including: statements regarding the expected timing and structure of the Proposed Transaction; the ability of the parties to negotiate, enter into and complete the Proposed Transaction; the expected benefits of the Proposed Transaction, such as improved operations, enhanced revenues and cash flow, synergies, growth potential, market profile, business plans, expanded portfolio and financial strength; the competitive ability and position of Emerson following completion of the Proposed Transaction; legal, economic and regulatory conditions; and any assumptions underlying any of the foregoing. Forward-looking statements concern future circumstances and results and other statements that are not historical facts and are sometimes identified by the words “may,” “will,” “should,” “potential,” “intend,” “expect,” “endeavor,” “seek,” “anticipate,” “estimate,” “overestimate,” “underestimate,” “believe,” “plan,” “could,” “would,” “project,” “predict,” “continue,” “target” or other similar words or expressions or negatives of these words, but not all forward-looking statements include such identifying words. Forward-looking statements are based upon current plans, estimates and expectations that are subject to risks, uncertainties and assumptions. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those indicated or anticipated by such forward-looking statements. We can give no assurance that such plans, estimates or expectations will be achieved and therefore, actual results may differ materially from any plans, estimates or expectations in such forward-looking statements. Important factors that could cause actual results to differ materially from such plans, estimates or expectations include, among others: (1) the outcome of any discussions between Emerson and the Company with respect to the Proposed Transaction, including the possibility that the parties will not agree to pursue a business combination transaction or that the terms of any such transaction will be materially different from those described herein, (2) that one or more closing conditions to the Proposed Transaction, including certain regulatory approvals, may not be satisfied or waived, on a timely basis or otherwise, including that a governmental entity may prohibit, delay or refuse to grant approval for the consummation of the Proposed Transaction, may require conditions, limitations or restrictions in connection with such approvals or that any required approval by the stockholders of the Company may not be obtained; (3) the risk that the Proposed Transaction may not be completed in the time frame expected, or at all; (4) unexpected costs, charges or expenses resulting from the Proposed Transaction; (5) uncertainty of the expected financial performance of Emerson following completion of the Proposed Transaction; (6) failure to realize the anticipated benefits of the Proposed Transaction, including as a result of delay in completing the Proposed Transaction or integrating the business of the Company with the business of Emerson; (7) the ability of Emerson to implement its business strategy; (8) difficulties and delays in achieving revenue and cost synergies; (9) inability to retain and hire key personnel; (10) the occurrence of any event that could give rise to termination of the Proposed Transaction; (11) potential litigation in connection with the Proposed Transaction or other settlements or investigations that may affect the timing or occurrence of the contemplated transaction or result in significant costs of defense, indemnification and liability; (12) evolving legal, regulatory and tax regimes; (13) changes in economic, financial, political and regulatory conditions, in the United States and elsewhere, and other factors that contribute to uncertainty and volatility, natural and man-made disasters, civil unrest, pandemics (e.g., the coronavirus (COVID-19) pandemic (the “COVID-19 pandemic”)), geopolitical uncertainty, and conditions that may result from legislative, regulatory, trade and policy changes associated with the current or subsequent U.S. administration; (14) the ability of Emerson and the Company to successfully recover from a disaster or other business continuity problem due to a hurricane, flood, earthquake, terrorist attack, war, pandemic, security breach, cyber-attack, power loss, telecommunications failure or other natural or man-made event, including the ability to function remotely during longterm disruptions such as the COVID-19 pandemic; (15) the impact of public health crises, such as pandemics (including the COVID-19 pandemic) and epidemics and any related company or governmental policies and actions to protect the health and safety of individuals or governmental policies or actions to maintain the functioning of national or global economies and markets, including any quarantine, “shelter in place,” “stay at home,” workforce reduction, social distancing, shut down or similar actions and policies; (16) actions by third parties, including government agencies; (17) potential adverse reactions or changes to business relationships resulting from the announcement or completion of the transaction; (18) the risk that disruptions from the Proposed Transaction will harm Emerson’s and the Company’s business, including current plans and operations; (19) certain restrictions during the pendency of the acquisition that may impact Emerson’s or the Company’s ability to pursue certain business opportunities or strategic transactions; (20) the ability to meet expectations regarding the accounting and tax treatments of the Proposed Transaction; and (21) other risk factors as detailed from time to time in Emerson’s and the Company’s reports filed with the SEC, including Emerson’s and the Company’s annual report on Form 10-K, periodic quarterly reports on Form 10-Q, periodic current reports on Form 8-K and other documents filed with the SEC. These risks, as well as other risks associated with the Proposed Transaction, will be more fully discussed in any proxy statement(s) and other relevant materials related to the Proposed Transaction if and when they are filed with the SEC. While the list of factors presented here is, and the list of factors to be presented in any such proxy statement(s) or materials will be, considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. Any forward-looking statements speak only as of the date of this communication.
