Masimo Board of Directors Authorizes Management to Evaluate the Separation of Consumer Business

Masimo (NASDAQ: MASI), a global leader in non-invasive monitoring technologies and audio consumer products, announced late Friday that its Board of Directors has authorized management to evaluate a proposed separation of its consumer business. The consumer business includes audio brands such as Marantz, Bowers & Wilkins, Denon, Classe and Polk Audio that Masimo acquired in 2022 with the purchase of Sound United.

It was business as usual this weekend for Masimo consumer with one of the largest presence at the Montreal Audio Show that concluded Sunday.

With the announcement of Masimo’s purchase of Sound United, most on Wall Street couldn’t understand the synergy of a collection of highly respected audio brands integrating with Masimo’s massively profitable and core healthcare business. Masimo’s share price fell close to 40% when the company disclosed the Sound United Acquisition.

With Masimo’s shares in a freefall, activist investor Politan Capital Management disclose a 9% ownership stake in Masimo a few months after the Sound United acquisition and then sued the company for what Politan saw as mismanagement of Masimo.  Politan succeeded in securing two seats on the Masimo Board and really, anyone who has been following this story will not find Friday’s announcement that the audio brands will be separated from the core company, a surprise.

Masimo is the owner of some of the biggest names in consumer audio including Denon.

What is not clear is whether this is the first stage of an ultimate sale of the audio brands by Masimo, either as a group or individually, or if this is more like Google becoming Alphabet, with Google now a division inside the parent company. Whether Masimo keeps the audio division as a standalone company or ultimately sells the brands, Wall Street as responded favourably to the decision of the consumer audio division no longer part of the publicly traded Masimo Corporation. Shares of Masimo are up 9% in after hours trading.  Below is the release provided by Masimo:

The Board and management will evaluate the proposed structure of the separation. Masimo expects that the separation will include its consumer audio and consumer health products, including the Stork baby monitor and the Freedom smart watch and band. Masimo will retain its professional healthcare and telehealth products. Masimo expects that this will improve the profitability of the healthcare business. 

Joe Kiani is expected to remain Chairman and CEO of Masimo and to be named Chairman of the newly created company. Masimo will seek to complete the separation as soon as feasible, subject to completion of due diligence, completion of definitive agreements, submission and clearance of filings with the Securities and Exchange Commission and the receipt of other applicable regulatory approvals.

“I truly believe there is tremendous opportunity to increase not just the lifespan but the healthspan of people by taking healthcare into the home,” said Mr. Kiani. “We have unique and necessary technologies to make what I’ve been calling 22nd Century healthcare happen in the next few years. I proposed a separation of the consumer business in January and the Board has agreed to move forward. This approach is expected to maximize shareholder value as well as give both Masimo healthcare and the new consumer business the best path for success.”

Masimo is also reaffirming its financial guidance for the first quarter and fiscal year 2024.
