Signify drops UV-C products aimed at surfaces

More than a year ago, Signify CEO Eric Rondolat described the company’s push into the ultraviolet C-band disinfection application as a “marathon,” not a sprint. The analogy now looks more apt than ever. Just like some runners drop out of 26-mile races, Signify has withdrawn some UV-C products in its germicidal UV quest.

The company has eliminated UV-C products aimed at eradicating the SARS-CoV-2 virus from surfaces, Rondolat told analysts on a call to discuss overall second-quarter financial results on Friday. The company continues to offer UV-C products centered on air disinfection, he said.

The “obsolescence” of surface-oriented products contributed to a “substantial” decline in gross margins for the quarter, Rondolat noted, pointing out that other factors were inflation including the rising cost of energy, ongoing supply chain difficulties, COVID-19 lockdowns in China, the strengthening of the Chinese renminbi*, and the discontinuation of conventional horticultural lighting products as efficient LEDs grow more popular due to soaring energy prices.

Signify adjusts EBITA guidance

For the quarter ended June 30, overall company revenue was €1.84 billion, marking a 5.1% increase in comparable sales over the second quarter of 2021. Some of the increase came from price increases amid global inflation.

While net income grew 203% to €248 million, Rondolat chose instead to focus analysts’ attention on “a gross margin decline of 290 basis points, which is quite substantial.” Adjusted EBITA margin tumbled to 9.5% from 10.9%, leading the company to revise its adjusted EBITA margin guidance for the year downward to between 11% and 11.4%, whereas it had been forecasting continued improvement. Adjusted EBITA itself slipped 0.5%, to €174 million from €175 million, while overall EBITA rose 150% to €340 million from €136 million.

Shifting away from surfaces

The discontinuation of surface-oriented UV-C products represents Signify’s most direct acknowledgment yet that its big bet on UV-C products has so far fallen short of a big payout.

In the early days of the COVID outbreak, Signify launched a portfolio of 12 UV-C product families aimed at deactivating the virus in air, on surfaces, and on objects. UV-C had been proven to deactivate SARS-CoV-2 at specific dosage.

But over the ensuing two years, LEDs Magazine suggested several times that sales did not seem to be living up to expectations. About eight months into the initiative, Rondolat characterized the market as “an education”. A few months later, nearly a year after the June 2020 launch, he conceded that the UV-C business is “less of a sprint, and more of a marathon.”

Last October, Signify revamped its approach to the market as it stopped supplying UV-C light sources to OEM manufacturers who would build them into their own goods. Instead, Signify focused solely on its own finished GUV products.

Then, last Friday, Rondolat revealed that the company is eliminating its surface-oriented UV-C products.

“When we started the UV-C business, we were targeting surface and air,” he said. “In hindsight, the business is more geared towards air disinfection. There’s 10,000 times more infection that comes from air than from surfaces. We had products that we developed for surface that were declared obsolete.” The “obsolescence on two very specific businesses” (the other being conventional horticultural lighting products) contributed to the 290-basis-point margin hit, Rondolat told one analyst.

In retrospect, it’s no coincidence that when signs of liveliness began picking up in the UV-C stable, they came from the air disinfection portfolio, such as when Signify sold into a Taiwanese restaurant chain and the Munich school system earlier this year.

Rondolat did not provide an update on overall UV-C sales or indicate whether the third category of GUV products — those aimed at objects — has been a viable one. LEDs has requested more information.

Meanwhile, Rondolat gave an upbeat account of how soaring energy prices are sparking renewed interest in energy-efficient LEDs and LED services. LEDs will report on this and other insights from the second-quarter call separately.
