*Emerson to Host Conference Call to Discuss Proposal Today at 8:30 a.m. Eastern Time*

 

**ST. LOUIS, Missouri – January 17, 2023 – Emerson (NYSE: EMR) today announced that it submitted a proposal to the Board of Directors of National Instruments ("NI") (NASDAQ: NATI) to acquire NI for $53 per share in cash at an implied enterprise value of $7.6 billion.**

The proposal, which is not subject to any financing conditions, was submitted to NI on November 3, 2022, and represents an improvement over an initial $48 per share proposal submitted on May 25, 2022. Emerson has made numerous attempts to engage constructively with NI in private since May 16, 2022, as outlined in the correspondence below. Full details, including Emerson's previous correspondence with NI, are available at <u>www.MaximizingValueAtNI.com</u>.

The proposal represents:

&nbsp;&nbsp;&nbsp;&nbsp;• Immediate and certain cash
value for all NI shareholders;

&nbsp;&nbsp;&nbsp;&nbsp;• A 32% premium to NI's
closing share price as of January 12, 2023, the day prior to NI's public announcement of a strategic review on January 13, 2023;

&nbsp;&nbsp;&nbsp;&nbsp;• A 45% premium to NI's
closing share price as of November 3, 2022, the day Emerson submitted its latest proposal to acquire NI;

&nbsp;&nbsp;&nbsp;&nbsp;• A 38% premium to the volume
weighted average price for the last 30 trading days ending January 12, 2023; and

&nbsp;&nbsp;&nbsp;&nbsp;• A 23% premium to NI's
52-week high intra-day share price of $43.12, as of January 12, 2023.

"Although Emerson would have preferred to reach an agreement privately, given NI's announcement that it is undertaking a strategic review, and after refusing to work with us toward a premium cash transaction over the past eight months, we are making our interest public for the benefit of all NI shareholders," said Lal Karsanbhai, President and Chief Executive Officer of Emerson. "Acquiring NI is another step forward in Emerson's journey to develop a cohesive, higher growth and higher margin portfolio and build on its global automation focus. As Emerson outlined at our recent Investor Conference, we are transforming our portfolio toward higher-growth automation markets aligned with secular macro trends, which will deliver significant growth and profitability for years to come."

Mr. Karsanbhai continued, "We have long admired NI and believe that combining its best-in-class electronic test and measurement product and software offerings with Emerson's industry-leading

automation technology and software would enhance our ability to bring comprehensive solutions to a diverse set of end markets, accelerating growth and positioning Emerson to create significant shareholder value. We stand ready to work immediately with NI's Board and management team to reach an agreement that would provide a compelling premium and certain cash value today for all NI shareholders."

**Combination Would Advance Emerson's Global Automation Focus**

The proposed transaction continues Emerson's transformation into a global automation company. Benefits of the transaction include:

&nbsp;&nbsp;&nbsp;&nbsp;· Aligned with Emerson's Portfolio Transformation Into a Cohesive, Higher Growth, and More Profitable Company: Emerson
is actively transforming its portfolio to create a higher value, cohesive industrial technology portfolio serving a diversified set of
end markets. With NI, Emerson would gain a strong, complementary portfolio of differentiated electronic test and measurement offerings,
and a technology stack of industry-leading intelligent devices, controls and software that complements Emerson's technology stack
in its core automation markets. As outlined at Emerson's November 29, 2022 Investor Conference, test and measurement is one of Emerson's
four priority segments.

&nbsp;&nbsp;&nbsp;&nbsp;· Further Diversification of End Markets: With favorable long-term trends and an estimated priority
target TAM of $35 billion, test and measurement is a fast-growing and complementary adjacency to Emerson's portfolio. This acquisition
would enable Emerson to further expand and diversify its customer base within highly attractive end markets with strong secular trends
including semiconductor, automotive and electric vehicles, and aerospace and defense.

&nbsp;&nbsp;&nbsp;&nbsp;· Significant Financial Benefits: The transaction is expected to be accretive to Emerson's adjusted
EPS in the first year, meets Emerson's communicated returns threshold and will improve Emerson's overall growth. NI has an
attractive financial profile, with approximately 70% gross margins. NI's business has strong positions in attractive and growing
markets, creating sustainable top line growth potential. Emerson sees significant potential for profit and cash flow improvement across
the NI business by applying proven operational excellence and productivity levers through Emerson's Management System.

&nbsp;&nbsp;&nbsp;&nbsp;· Emerson's Strong Commitment to the Transaction: Emerson believes its premium proposal will
bring clear and realizable value to NI shareholders, who have faced years of share price underperformance across nearly any period. Underscoring
its commitment to consummating a transaction, Emerson has purchased 2.3 million shares of NI stock and has received approval under HSR <sup>1</sup> to increase its stake. Emerson believes that there is a path to a friendly transaction and urges NI shareholders to make their views known
to NI's management and Board. Furthermore, Emerson is prepared to nominate directors for election to NI's Board.

**Emerson's Public Proposal Follows Eight Months of Delay and Lack of Engagement**

Emerson's first outreach to NI regarding a potential all-cash acquisition was on May 16, 2022, and Emerson's initial $48 per share proposal was formalized in a letter on May 25, 2022. For eight months, NI delayed and refused to engage meaningfully with Emerson, as outlined in the correspondence below. In addition, after receiving the initial May 25, 2022 proposal from Emerson, NI not only refused to engage with Emerson – it repurchased more than 2 million shares at an average weighted price of $40.25, the

<sup>1</sup> Hart-Scott-Rodino Antitrust Improvements Act of 1976

largest quarterly repurchase in its history on a dollar basis, depriving its shareholders of the opportunity to realize immediate cash value through the transaction price, which is significantly above the repurchase price.

In a November 3, 2022 letter, Emerson outlined the terms of an improved all-cash proposal of $53 per share and highlighted its numerous attempts to engage with NI to that date. On November 15, 2022, NI responded to Emerson, indicating that it had created a working group of its Board to examine Emerson's proposal in greater detail, as well as evaluate options with the assistance of advisors.

In the more than two months since, NI continued to resist engaging meaningfully with Emerson to work toward an agreement. Eight months after Emerson's approach, NI agreed to a January 4, 2023 meeting with representatives from Emerson, which was followed by one additional conference call. During these discussions, NI shared very limited, high-level information about its business and continued to demonstrate its unwillingness to provide more detailed information, including refusing to respond to key diligence questions provided ahead of the meeting. NI then informed Emerson that this would be the extent of its engagement. In a letter dated January 11, 2023, Emerson reiterated its $53 per share proposal to acquire NI.

**NI Shareholders: Stop Your Board's Delay Tactics**

Emerson is disappointed that NI chose to announce a strategic review and put in place a poison pill on January 13, 2023, rather than engaging privately and constructively. NI did not respond to Emerson's latest letter sent on January 11 before its public announcement.

NI's strategic review announcement comes more than two months after the NI Board purportedly formed a working group to evaluate options with its advisors – with no results.

NI shareholders should understand that for eight months they have been deprived of the opportunity to realize certain cash value at a significant premium. Emerson urges NI shareholders to engage with their Board to ensure this public strategic review process is not merely another delay tactic.

Emerson has organized the resources to work expeditiously toward a transaction with NI, has shared a merger agreement with NI, and is prepared to transact promptly. Emerson has performed due diligence with publicly available information and would have only limited and specific confirmatory due diligence requirements. Additionally, Emerson does not anticipate any significant regulatory risks or delays given the complementary nature of the two businesses. Finally, the Emerson proposal is not subject to any financing conditions.

Emerson feels compelled to disclose the contents of all its correspondence with NI, beginning in May 2022, to make public its consistent and sustained track record of attempted engagement with NI, without any meaningful or constructive response. This correspondence is below and is also available at <u>www.MaximizingValueAtNI.com</u>.

**Investor Conference Call and Presentation**

Today, beginning at 7:30 a.m. Central Time / 8:30 a.m. Eastern Time, Emerson management will discuss the proposal during an investor conference call. Participants can access a live webcast available at www.Emerson.com/en-us/investors at the time of the call. A replay of the call will be available for 90 days on the company website and at www.MaximizingValueAtNI.com. Conference call slides will be posted in advance of the call on the company website and at www.MaximizingValueAtNI.com.

**Emerson's Correspondence with NI**

**May 25, 2022 – Emerson's First Offer Letter to NI**

Eric Starkloff

President and Chief Executive Officer

National Instruments Corporation

11500 N Mopac Expwy

Austin, TX 78759-3504

Dear Eric:

Further to my recent discussions with you, I am excited to present you with this proposal (the "Proposal") for the acquisition of all outstanding shares of National Instruments Corporation ("NI") by Emerson Electric Co. ("Emerson").

We are very excited about the combination of our two firms and the potential we can achieve together. Emerson has long admired NI as a technology leader in the electronic test and measurement industry, a complementary adjacency to our Automation Solutions business with a similar technology stack of intelligent devices, controls, and software. We have been particularly impressed with NI's portfolio including modular intelligent devices and the LabVIEW suite of offerings, as well as NI's industry stewardship over many decades in this space. Combining NI with Emerson would lead to significant opportunities for both of our teams and further develop our position as a premier global automation company.

In addition to the immediate value created for your shareholders as outlined in the Proposal, Emerson has demonstrated long term stewardship and investment in acquired businesses over many decades. Our industry leading Automation Solutions platform was built through a combination of sustained organic investments as well as strategic acquisitions of highly innovative businesses including Rosemount, Micro Motion, Fisher, and most recently our acquisition of majority control in AspenTech. All of these businesses have thrived under Emerson ownership and are leaders in their respective markets. With the potential acquisition of NI, we are looking to continue our long history of stewardship and commitment to growth, development, and engineering leadership.

With that backdrop, I am pleased to present you and your Board with this Proposal:

**<u>Valuation</u>**

Emerson proposes to purchase 100% of the outstanding common stock of NI for $48 in cash per common share, which implies an equity value of $6.49 billion and an enterprise value of $6.67 billion. We believe our Proposal provides significant value to your shareholders:

A 39% premium to NI's closing share price as of May 24, 2022;

A 36% premium to the volume weighted average price for the last 30 trading days ending May 24, 2022;

A 4% premium to the 52 week high trading price as of May 24, 2022

**<u>Financing</u>**

Our Proposal is not subject to any financing condition and would be financed from cash on hand, committed lines of credit and/or other available sources of financing.

**<u>Regulatory</u>**

While applicable regulatory approvals will be required, we do not expect there to be substantive impediments to closing. We note the complementary nature of our respective businesses.

**<u>Due Diligence</u>**

This Proposal is based on publicly available information under the assumption that it presents fairly and completely NI and its businesses and its outstanding debt and share count. It is subject to the completion of customary and confirmatory due diligence (e.g., tax, environmental, legal, etc.). We are prepared to move quickly to complete such due diligence when appropriate.

**<u>Timing</u>**

Emerson is prepared to proceed immediately to work with NI and its advisors to complete due diligence and to negotiate a mutually agreeable merger agreement (the "Definitive Agreement") in parallel. It is our expectation that the signing of the Definitive Agreement and announcement can be achieved in 4-6 weeks.

We have no current plan to disclose this letter and assume that you do not intend to either. Our strong preference is to work constructively and expeditiously with you and your board to announce a Definitive Agreement.

**<u>Board Review</u>**

This Proposal has been reviewed with Emerson's board of directors who support the proposed transaction. The final approval of Emerson's board of directors would be required prior to entering into the Definitive Agreement.

**<u>Other</u>**

The Definitive Agreement would be negotiated and executed by Emerson and NI and closing would be conditioned upon required NI shareholder approval, required regulatory approvals and other customary conditions. Emerson shareholder approval will not be required.

To reiterate, our Proposal – all cash consideration with no financing contingency and no substantive regulatory impediments – provides both significant value and certainty to NI's shareholders. We are prepared to move very quickly to complete our due diligence and sign definitive agreements.

We are highly enthusiastic about the prospects of what we can achieve together. On behalf of Emerson, I thank you again for the dialogue thus far and for your consideration of this Proposal. We look forward to hearing from you.

Sincerely,

Lal Karsanbhai

President and Chief Executive Officer

Dear Eric and Michael:

I received your letter dated Thursday, June 16th, responding to our proposal from Wednesday, May 25th (the "Proposal") for the acquisition of all of the outstanding shares of National Instruments Corporation ("NI") by Emerson Electric Co. ("Emerson"). I am disappointed in your response and the lack of engagement from you and your Board to what is an extremely attractive Proposal for the shareholders of NI.

We have followed NI for many years and believe that the Proposal is a unique opportunity for NI shareholders to realize a certain cash value and to accelerate the execution of your vision to automate test across the product lifecycle. We are offering an immediate financial benefit to your shareholders, and a high-quality home for NI, benefiting your employees, customers, suppliers and communities.

Our Proposal to acquire all of NI's outstanding shares at $48 per share in cash offers significant value to your shareholders measured against both short and longer-term metrics, specifically a:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 51% premium to NI's closing share price as of June 21, 2022;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 41% premium to the volume weighted average price for the last 30 trading days ending June 21, 2022;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 39% premium to NI's closing share price as of May 24, 2022 (the day prior to when we made
the Proposal); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 4% premium to the 52 week high trading price as of June 21, 2022.

We are highly confident your shareholders would view our cash offer favorably and recent market data points reinforce this view, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The last time NI's share price closed above $48 was on December 6th, 2018. NI's share
price has underperformed both the broader market and its key peer, Keysight, since then, with the stock down 34% in a period where the
NASDAQ Index gained 54% and Keysight gained 125%;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Four of the six brokers who cover NI have reduced their 12 month forward price targets following
your Q1 earnings with the median price target being reduced from $50 to $43.50; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The top 10 active shareholders as of the end of Q1 2021 owned approximately 19% of the company with
an estimated weighted average cost basis of $35. Over the past year, 8 of those 10 shareholders have reduced their positions and sold
stock materially below the price we are offering.

We prefer to engage in collaborative, bilateral discussions with minimal distraction to your management team to reach an agreement privately. Your letter referenced "significant and steady

increases in bookings and revenue" as well as "strengthened operational performance and advances in technology". We look forward to learning more about your internal plan and are confident that with access to limited non-public information after signing an NDA, we could work with you to find additional value that would allow us to increase our Proposal.

We are prepared to engage immediately and have organized the resources to move towards a transaction expeditiously, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *Diligence:* We have performed extensive outside-in due diligence on NI over an extended period.
As a result, we have limited and specific confirmatory due diligence requirements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *Timing:* We are ready to begin our confirmatory due diligence exercise and we would work towards
signing and announcing a definitive agreement within four weeks.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *Regulatory:* We do not anticipate any significant regulatory risks or delays given the complementary
nature of our businesses.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *Financing:* Our Proposal is not subject to any financing condition and would be financed from
cash on hand, committed lines of credit and/or other available sources of financing. Emerson is an A2/A rated company with a strong balance
sheet. We have obtained a Highly Confident Letter from Goldman Sachs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *Advisors:* We have engaged Goldman Sachs & Co. LLC and Centerview Partners LLC as our
financial advisors and Davis Polk Wardwell LLC as our legal counsel.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *Certainty:* Our Board of Directors has reviewed and supports the proposed transaction. Emerson
shareholder approval will not be required.

Emerson considers this Proposal to be of the highest strategic priority. We are very motivated to conclude a transaction that benefits both companies as well as our respective shareholders. Please confirm receipt of this letter. Given the upcoming July 4th holiday, we recognize you may not be able to get back to us until the week of July 11th. I look forward to hearing from you by then at the latest.

Sincerely,

Lal Karsanbhai

**November 3, 2022 – Emerson's Third Offer Letter to NI**

Eric Starkloff

President and Chief Executive Officer

Michael E. McGrath

Chairman of the Board

National Instruments Corporation

11500 N Mopac Expwy

Austin, TX 78759-3504

Dear Eric and Michael:

I am writing to follow up on your August 2nd response to our June 22nd letter which reiterated our proposal for the acquisition of all of the outstanding shares of National Instruments Corporation ("NI") by Emerson Electric Co. ("Emerson"). After receiving your terse response and continued refusal to engage with Emerson

for the benefit of NI's shareholders, we decided to wait to see if your revised guidance, investor day communication, and Q3 results might fundamentally alter investors' views of NI's value or signal an acceleration in NI's outlook that we could incorporate into our thinking before reaching out to you again.

**<u>Recap of Events of the Past Six Months</u>**

Over a period starting almost 6 months ago, we have consistently been prepared to provide your shareholders an all-cash offer at a meaningful premium, which your Board has repeatedly rebuffed and refused to provide even limited financial information. Given the time that has elapsed, we believe the context of our outreach, your Board's refusal to engage, and NI's investor communications since receiving our first offer are important to summarize:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *May 16th:* My initial outreach to you was premised on meeting in person to introduce myself
and shape a compelling all-cash offer for your shareholders. I was surprised that you would not meet with me and instead offered a phone
call.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *May 22nd:* In an extremely brief phone call, you reiterated you would not engage and suggested
we send a letter if Emerson should want to acquire NI.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *May 25th:* I sent you a letter describing our all-cash offer at a significant premium to NI's
current and historical trading levels. The offer was based on public information and outlined key terms related to deal certainty, including
no financing contingency.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *June 16th:* You sent a very short response letter refusing to engage, with limited elaboration
to your Board's reasons.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *June 22nd:* After your negative response on June 16th, I again attempted to engage with you
with a second letter describing our all-cash offer on June 22nd in which I requested access to limited additional information to help
find additional value to improve our proposal and asked for a response by July 11th.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *July 6th:* You responded that you could not get back to me by July 11th, and instead would
get back to me after your earnings call at the end of the month.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *July 28th Q2 Earnings Call*: Despite solid order momentum, NI's performance demonstrated
continued challenges to expanding margins, with gross margins down year-over-year by more than 400 bps and only a 2% incremental margin
on 14% sales growth. With the knowledge of our approach (that you did not disclose to your shareholders), and despite the headwinds and
weak financial performance, you substantially increased your outlook for 2023, guiding to a mid-teens topline growth rate and 300 basis
points of margin improvement, a margin improvement three times larger than your prior guidance only three months earlier when you released
1st quarter earnings, at a time when you were not aware of Emerson's interest in acquiring NI.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *August 2nd:* You sent a second, similarly curt response letter refusing to engage.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *August 11th:* You announced you would hold your annual investor day on September 15th.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *September 15th Investor Day:* You reaffirmed the same 2023 guidance as provided with Q2 earnings
and provided additional guidance to achieve a further 200 bps operating margin expansion by 2025. Despite your positive tone, your shares
fell 3.2% on the day, underperforming the market as investors and analysts continue to doubt NI's ability to execute and deliver
these results given its historical track-record and the current operating environment. In particular, the market remains unconvinced about
NI's ability to expand EBIT margins through software and system-level solutions as well as the sustainability of order trends and NI's
ability to capitalize on secular opportunities in ADAS/EVs/5G.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *October 27th Q3 Earnings:* Despite achieving record quarterly revenue, NI's share price
declined 3.0% the next day (a day in which the NASDAQ Index was up 2.9%) given decelerating order rates, as well as continued supply chain
challenges and the potential impact of a deteriorating macro. NI's Q4 guidance was below street expectations, despite reaffirming
the margin expansion guidance for 2023. Since your announcement, research has highlighted how NI continues to be a "wait and see"
company as evidence of margin expansion was pushed out once again. The market is particularly concerned about your ability to achieve
your expected growth in the face of a worsening economic outlook in many markets, particularly in your portfolio businesses. Factoring
in these uncertainties, almost all brokers revised their estimates for both Q4 and 2023 downwards as well as their target prices

**<u>Improved Proposal</u>**

From our first outreach, we have preferred to engage with you privately and have been committed to improving our offer to reflect the outlook for your company incorporating the latest financial information. Although we question the motivations for your updated guidance, we do believe in the long-term potential of the NI business under Emerson's leadership and, in the spirit of achieving engagement, we are willing to incorporate your updated outlook to improve our offer. As such, we are increasing our Proposal, from $48 per share to $53 per share (our "Improved Proposal").

Under our Improved Proposal, Emerson proposes to purchase 100% of the outstanding common stock of NI for $53 in cash per common share which implies an equity value of $7.1 billion and an enterprise value of $7.6 billion. Our Improved Proposal delivers compelling all cash value and provides credit for significant future earnings, including your recently updated guidance. Rather than wait for you to achieve an uncertain 2023, our cash offer gives your shareholders immediate credit today. The offer provides substantial premiums to both current and historical metrics, specifically:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 45% premium to NI's closing share price as of November 3, 2022;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 37% premium to the volume weighted average price for the last 30 trading days ending November 3,
2022;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 53% premium to NI's closing share price as of May 24, 2022 (the day prior to when we made
the original Proposal).

For reference, the last time NI's share price closed above $53 was on March 12th, 2018. Since then, NI's share price has underperformed both the broader market and its key peer, Keysight, with the stock down 31% in a period where the NASDAQ Index gained 36% and NI's closest peer Keysight gained 206%.

**Emerson is Prepared to Move Quickly**

We believe this Improved Proposal presents the best and most certain path to maximize value for NI shareholders. We are prepared to engage with NI's Board and management team immediately and have organized the resources to work towards a transaction expeditiously.

To emphasize the level of work completed and ability to move with certainty and speed, we reiterate to you our proposed next steps consistent with our prior letters:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *Diligence:* We have performed extensive outside-in due diligence on NI over an extended period.
As a result, we have limited and specific confirmatory due diligence requirements only.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *Timing:* We are ready to begin our confirmatory due diligence exercise and we would work towards
signing and announcing a definitive agreement within four weeks.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *Regulatory:* We do not anticipate any significant regulatory risks or delays given the complementary
nature of our businesses.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *Financing:* Our Proposal is not subject to any financing condition and would be financed from
cash on hand, committed lines of credit and/or other available sources of financing. Emerson is an A2/A rated company with a strong balance
sheet. We have obtained a Highly Confident Letter from Goldman Sachs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *Advisors:* We have engaged Goldman Sachs & Co. LLC and Centerview Partners LLC as our
financial advisors and Davis Polk & Wardwell LLP as our legal counsel. We have also engaged Joele Frank on public relations and Innisfree
as our proxy solicitor.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· *Certainty:* Our Board of Directors has reviewed and supports the proposed transaction. Emerson
shareholder approval will not be required.

**<u>Next Steps</u>**

We have invested considerable time and resources and remain fully committed to pursuing this transaction. It is our sincere hope that your Board—having had multiple opportunities to communicate its strategy and outlook to the market with no material change in NI's share price—will view this Improved Proposal favorably and now engage with us in a constructive dialogue. While it is our preference to work with your Board privately and collaboratively towards a potential transaction, another refusal to engage will force us to ensure your shareholders can assess our Improved Proposal directly. In preparation for all options, we would note:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· We have accumulated 2.3 million NI shares in the open market and intend to file for HSR approval
to facilitate additional purchases; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Given your Board's repeated attempts to move NI's share price higher have been unsuccessful,
your remaining defense is neither your operational strategy nor shareholder support for management but rather NI's staggered board.
As such, we are prepared to run a slate of directors specifically targeting the two members up for re-election, your Chairman and former
CEO, which will provide NI's shareholders with an opportunity to express their views to your Board on its refusal to engage with
us.

I continue to be available to meet with you at your convenience and have also instructed our financial and legal advisors to make themselves available to meet with your advisors. Given you have now been in possession of a Proposal from Emerson since May, and now an Improved Proposal, I request that you respond promptly to this letter. I look forward to hearing a more constructive answer and stand ready to engage.

Sincerely,

Lal Karsanbhai

Please provide an update on your process and advise when the advisors can connect, as well as timing for the meeting with the working group and management.

Dear Mr. Dixon,

Attached please find Emerson's demand as a stockholder of National Instruments Corporation ("NI") for inspection of books and records of NI. Please note the statutorily mandated initial compliance date of Thursday, December 22, 2022 and continuing thereafter through NI's next annual general meeting of its stockholders. The attached demand provides the contact information for coordinating NI's response through Emerson's outside counsel, Davis Polk.

I also would like to follow-up on my letter dated Wednesday, December 7, 2022 to you requesting documentation mandated by NI's bylaws in connection with the nomination of directors and your letter earlier today. In your letter you advised that you will provide the documents "shortly" without more specificity. We are concerned that NI's delay in responding to this straightforward request will frustrate or impair Emerson's ability to nominate directors. We ask that NI respond fully to the request no later than Sunday, December 18, 2022. In that regard, we ask that you provide the supplemental information requested in my December 7 letter in addition to the two documents.

We look forward to prompt and complete responses on all of the above matters.

From: Eric Starkloff<br> Sent: Friday, December 16, 2022<br> To: Lal Karsanbhai<br> Subject: Re: Re: Re: Re: Follow up to NI letter dated August 2nd

Lal,

Following up on our call yesterday, just to confirm that your suggestion of getting together the first week of January in Austin works for us, and I'm looking forward to seeing you in person. Does Wednesday, January 4 work for you? If so, we can work to arrange the logistics. And based on your comments around the areas you are interested in learning more about our business, I think the meeting will be a mutually valuable one.

In preparation for that information sharing, I'll have our lawyers at Wachtell Lipton (Adam Emmerich, Sabastian Niles and Lina Tetelbaum) send along a proposed NDA. Please let me know who they should send it to from your advisor team. As we discussed yesterday, we are not seeking to prevent you from making board nominations for our next annual meeting, and expect we can get the NDA organized and agreed in short order.

Looking forward to seeing you in January. Best wishes for a happy holidays.

**January 11, 2023 – Emerson's Fourth Offer Letter to NI**

Eric Starkloff

President and Chief Executive Officer

Michael E. McGrath

Chairman of the Board

National Instruments Corporation

11500 N Mopac Expwy

Austin, TX 78759-3504

Dear Eric and Michael:

I am writing to follow up on our November 3rd letter which outlined our improved proposal for the acquisition of all of the outstanding shares of National Instruments Corporation ("NI") by Emerson Electric Co. ("Emerson").

We appreciate you and your team hosting us in Austin on January 4th and the one follow-up call between the teams on January 9th. As you have seen through our discussions, we have a deep understanding of the test and measurement sector and specifically NI. While it has been helpful to receive some additional information on your business and plans, the superficial information your team shared has not addressed the 30 focused questions that we provided ahead of time, and as such we are not yet able to change our view on the financial outlook for NI.

Based on what you have shared to date, we reiterate our proposal for Emerson to purchase 100% of the outstanding common stock of NI for $53 in cash per common share. Our offer

provides shareholders with credit today for significant future earnings, including your recently updated guidance at attractive premiums:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 37% premium to NI's closing share price as of January 10, 2023; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 45% premium to NI's closing share price as of November 3, 2022 (when we increased our proposal
to $53 a share).

From our first outreach in May 2022, we have attempted to work with you privately to see if we could reach a deal and we are highly confident we could announce a deal within days and by no later than your Q4 results on January 31st. To that end, we would be willing to extend the standstill agreement by one week and may see the potential for a very modest increase in value, subject to the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Receiving the outstanding business diligence responses to our prioritized list of 30 questions that
we shared on January 6th, as outlined in Annex A;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Receiving details on all changes in compensation and benefits, equity awards (regular or special)
made and anticipated, beyond what has previously been disclosed in NI's SEC filings so we can determine if there are meaningful
new costs incurred that may impact our ability to modestly increase our offer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Davis Polk will share with Wachtell a draft merger agreement reflective of our proposal and we expect
meaningful engagement on negotiating the agreement and aligning on key deal terms;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Arranging discussions between bankers to agree and align on the process and timeline to announcing
a transaction by your Q4 results, and;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Receiving a full response from your outside counsel to the information requested pursuant to the
Section 220 Demand for Stockholder Information which we are entitled to as holders of 2.3 million shares of NI.

We believe our offer is compelling and that there is a path to working with your Board privately and collaboratively towards a potential transaction. We are in a position to move very quickly to finalize customary confirmatory diligence and negotiate the merger agreement, and subject to receiving the information requested, may see the potential for a very modest increase in value. However, if you are not willing to share the information requested, it will require us to reach out to your shareholders directly.

I look forward to hearing from you promptly.

Sincerely,

Lal Karsanbhai

President and Chief Executive Officer

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.

Immediate, Compelling And Certain Value For NI Shareholders January 17, 2023

![](image_173.jpg)

2 Dear NI Shareholder, Our proposed all - cash acquisition of NI is a clear and certain path to realizing increased value from your investment in NI. We are offering to acquire NI for $53 per share, a 32% premium to NI's closing share price as of January 12, 2023, the day pr ior to NI's announcement of a strategic review and a 38% premium to the 30 - day VWAP ending January 12, 2023. Emerson has long admired NI as a technology leader in electronic test and measurement and believes combining our two companie s w ould further develop our position as a premier global automation company. In this presentation, we provide an overview of why we firmly believe that our offer enables you to achieve an immediate, hig h - p remium return on your investment. • Compelling Premium and Value: $53 per share, all - cash • Transaction Certainty: No financing contingency, no expected regulatory concerns • Expedited Timeline: Ready to sign and announce quickly following substantive engagement by NI Emerson is committed to pursuing this transaction. Emerson has made numerous attempts to engage constructively with NI in pri vat e since May 2022 and for eight months, NI delayed and evaded our efforts. In November, NI noted that it had created a working group of it s B oard to examine Emerson's proposal in greater detail, as well as evaluate options with the assistance of advisors – and then last week, nearly two months later, NI announced publicly that it is initiating a review and evaluation of strategic options with its advisors and has ado pte d a poison pill. While we would have preferred to reach an agreement privately, we are making our interest public for the benefit of all NI sharehol der s. As a sign of our commitment, Emerson has purchased 2.3 million shares of NI and we have received HSR approval to increase our stake. We urge NI shareholders to engage with their Board to ensure this public strategic review process is not merely another delay ta ctic. Regards, Lal Karsanbhai President and Chief Executive Officer
