Emerson Electric Bids to Buy National Instruments for Nearly $7 Billion

Emerson Electric Co.

EMR -6.82%

has disclosed a nearly $7 billion offer to acquire

National Instruments Corp.

NATI 10.79%

, which it said it has been trying to buy for more than eight months.

Emerson, a St. Louis-based technology and engineering company, said it was offering $53 a share in cash for National Instruments, which it said represents an enterprise value of $7.6 billion. The offer represents a 32% premium over National Instruments’ closing price from last Thursday, the day before the Texas-based equipment and instrumentation company said its board was evaluating strategic alternatives and had already been approached by potential acquirers.

Emerson’s public proposal comes eight months after National Instruments rejected its offer for an acquisition at $48 a share, the company said. Emerson upped its bid to $53 a share in November, but now claims National Instruments has continued to spurn its advances.

National Instruments confirmed Tuesday that it had received Emerson’s offer but said it remains committed to the strategic review process it announced on Friday.

By making the offer public, Emerson is hoping to win over shareholders who until now “have been unaware of this opportunity to realize an immediate cash premium,” Chief Executive

Lal Karsanbhai

said Tuesday in a conference call.

“Emerson urges NI shareholders to engage with their board to ensure this public strategic review process is not merely another delay tactic,” he said.

National Instruments’ shares jumped more than 10% to $52.04 by the close of the Tuesday market. Emerson’s shares meanwhile fell almost 7% to a low of nearly $91 in one of their steepest drops since June 2020, according to Dow Jones Market Data.

Emerson said that picking up National Instruments’ portfolio of electronic test and measurement offerings would bolster its automation business while also adding to its adjusted earnings within the first year. The company isn’t putting any financing conditions on the deal, saying it can fund the transaction with cash on hand and existing lines of credit.

On a call with analysts, the company detailed eight months of snubs from the National Instruments board that started in May, when Emerson said it reached out for an in-person meeting about a potential deal and was instead offered a phone call with management. Emerson sent a formal letter soon after with its all-cash $48-per-share offer, but National Instruments turned it down, the company said.

National Instruments continued to rebuff offers to negotiate privately in the months that followed, Emerson said.

Emerson also noted that National Instruments purchased more than two million of its own shares at an average weighted price of $40.25 during that time. Mr. Karsanbhai criticized the company on Tuesday for launching one of its largest-ever buybacks for a per-share price that was well below Emerson’s offer.

Emerson reached out with its improved offer on Nov. 3 to buy National Instruments for $53 a share, which marked a 45% premium to the company’s share price at market close that day. The National Instruments board responded at the time that it had formed a working group to evaluate the proposal and weigh its strategic options, but otherwise refused to engage with Emerson, Emerson said.

National Instruments said Tuesday that it welcomes Emerson’s participation in its strategic review process but also thinks that negotiating exclusively with the company “would be detrimental to shareholders.”

“NI notes Emerson’s expressed disappointment in this effort to maximize NI shareholder value,” the company said.

One of Webb Space Telescope’s Primary Instruments Ready To See Cosmos in Over 2,000 Infrared Colors

“I’m so excited and thrilled to think that we’ve finally reached the end of this two-decade-long journey of Canada’s contribution to the mission. All four NIRISS modes are not only ready, but the instrument as a whole is performing significantly better than we predicted. I am pinching myself at the thought that we are just days away from the start of science operations, and in particular from NIRISS probing its first exoplanet atmospheres,” said René Doyon, principal investigator for NIRISS, as well as Webb’s Fine Guidance Sensor, at the University of Montreal.

With NIRISS postlaunch commissioning activities concluded, the Webb team will continue to focus on checking off the remaining five modes on its other instruments.

NASA’s work to align the James Webb Space Telescope is extending to more instruments

After James Webb Space Telescope officials released a stunning image of a single star, the team is ready to get other telescope parts in line with the observatory’s mirrors.

The $10 billion telescope successfully aligned with its near-infrared camera (NIRCam), as the star image showed. But the observatory still has four other instruments that it must be able to switch between with perfect alignment to obtain sharp images of distant objects.

The work will begin with the guiding instrument (called the Fine Guidance Sensor or FGS) and then extend to the other three instruments, a NASA update stated Thursday (March 17). Webb engineers expect that this process, called “multi-instrument multi-field alignment,” will take six weeks to complete.

Webb should complete its commissioning period around June, six months after launching on Dec. 25 on an ambitious mission to observe the universe from deep space and gather data on objects ranging from exoplanets to galaxies.

Switching between cameras in space is complicated, but the telescope will eventually be able to use multiple instruments at the same time, according to the update, which was written by Jonathan Gardner, Webb deputy senior project scientist at NASA’s Goddard Space Flight Center in Maryland.

Ground-based telescopes have the advantage of having engineers available on site to potentially remove instruments not needed in between investigations. However, on Webb and other space telescopes, the procedure is different.

“All the cameras see the sky at the same time; to switch a target from one camera to another, we repoint the telescope to put the target into the field of view of the other instrument,” Gardner wrote.

The goal of the new alignment, Gardner said, is to “provide a good focus and sharp images in all the instruments” while knowing the relative positions of each instrument’s field of view.

Last weekend, Gardner continued, engineers learned the positions of three near-infrared instruments in relation to the FGS, and updated that information in the software used for telescope pointing.

FGS reached its own milestone recently, which was finishing “fine guide mode.” That occurs when the guider zeroes in on a guide star to the instrument’s highest possible precision. Additionally, engineers are taking “dark” images to see what happens when the instrument has no light reaching it, which allows personnel to more precisely calibrate the instrument.

The last instrument to be aligned will be the mid-infrared instrument (MIRI) as it is awaiting a cryogenic cooler’s ability to bring it to its operating temperature of minus 448 degrees Fahrenheit (minus 267 degrees Celsius.)

Gardner also explained how the instruments will work together to look at a target.

“With parallel science exposures, when we point one instrument at a target, we can read out another instrument at the same time,” he said. “The parallel observations don’t see the same point in the sky, so they provide what is essentially a random sample of the universe.” 

Parallel data, he concluded, allows scientists to “determine the statistical properties of the galaxies that are detected. In addition, for programs that want to map a large area, much of the parallel images will overlap, increasing the efficiency of the valuable Webb dataset.”

Power On! Webb Space Telescope Turns On Instruments

Now begins the process of aligning all 18 mirror segments so that they work together as one.

Since the arrival of

The James Webb Space Telescope has reached it’s parking spot in space and has successfully powered up all of it’s instruments.

Marcia Rieke, a University of Arizona Regents Professor of Astronomy, is principal investigator for NIRCam. Her husband, George Rieke, also a Regents Professor of Astronomy, is the science team lead for MIRI.

While MIRI and some components of the telescope’s other instruments were powered on in the weeks after Webb’s December 25 launch, the final three instruments – including NIRCam – turned on in the past few days.

After the powered-on instruments undergo initial checks, the mission operations team’s next major step is to turn off instrument heaters. The heaters keep critical optics warm to protect them from water and ice condensation. As the instruments meet predefined criteria for overall temperatures, the team will shut off the heaters to allow the instruments to cool to final temperatures that will allow the infrared detectors to see faint objects in the night sky.

When NIRCam reaches about minus 244 degrees

Since the 18 mirror segments are not working in tandem yet, the alignment process will first create an image of 18 random, blurry points of light as the telescope points at star HD84406.

For the first few weeks of mirror alignment, the team will keep NIRCam trained on the star while making microscopic adjustments to Webb’s mirror segments. Ultimately, that collection of 18 blurry dots will become a focused image of a single star.

Cooling of the telescope and instruments will continue over the next month, with NIRCam ultimately reaching nearly minus 400 degrees Fahrenheit.

NASA has allotted 13% of Webb’s total observing time to UArizona astronomers. This gives the university more viewing time than any other astronomy center in the world. The National Science Foundation has ranked the University of Arizona No. 1 in astronomy and astrophysics research expenditures each year since 1988.
