Birkenstock warns in IPO filing that knock-offs on Facebook are a top risk

Birkenstock, the iconic sandal maker founded in 1774, filed its paperwork for an initial public offering on Tuesday, and warned investors of the risks posed by counterfeit brands that use social media to promote their products.
The footwear company, which was started in Germany and is now based in London, plans to go public on the New York Stock Exchange, under ticker symbol “BIRK.”
Birkenstock has long struggled to protect its intellectual property, as copycats have taken advantage of the brand’s popularity and premium prices to try and undercut the company with cheaper alternatives. In its prospectus, Birkenstock says that some of the competition comes from “private label offerings” from retailers, but there are also “knock-off products” that are stealing its IP and trying to convince people on Facebook and elsewhere on the web that the items are authentic.
“In the past, third parties have established websites to target users on Facebook or other social media platforms with ‘look alike’ websites intended to trick users into believing that they were purchasing Birkenstock products at a steep discount,” the filing said. “Should counterfeit products be successfully sold on e-commerce platforms managed by third parties, our brands and reputation could be damaged.”
Birkenstock doesn’t name Amazon anywhere in the 206-page — plus footnotes — filing, but it does say that it has “refrained, and we may in the future refrain, from using certain third-party websites to distribute our products due to the selling of counterfeit products on such platforms.”
Seven years ago, Birkenstock publicly quit Amazon in the U.S. due to an eruption of counterfeit and unauthorized sales on the site. The company also said at the time that it would no longer allow authorized Birkenstock merchants to sell on Amazon.
“The Amazon marketplace, which operates as an ‘open market,’ creates an environment where we experience unacceptable business practices which we believe jeopardize our brand,” then-Birkenstock USA CEO David Kahan wrote in a memo on July 5, 2016, addressed to “our valued Birkenstock partners.”
Kahan, whose title is now President Americas, went on to say that “policing this activity internally and in partnership with Amazon.com has proven impossible.”
Prior to its departure from Amazon, legions of Chinese sellers had been promoting Birkenstock’s flagship Arizona sandal for $79.99, or $20 below the retail price, according to CNBC’s reporting at the time.
Since 2016, according to the prospectus, Birkenstock has “significantly expanded” its direct-to-consumer efforts in e-commerce in the U.S. For the fiscal year ending Sept. 30, 2022, that channel represented 38% of revenue, the company said, adding that “one of our strategies is to continue to increase the proportion of our revenues from e-commerce.”
Subsequent to the Amazon clash, Birkenstock sold a majority stake in the company to LVMH-backed private equity firm L Catterton in February 2021. After the IPO, L Catterton will continue to own a majority of Birkenstock, according to the filing.
“We see ourselves as the oldest start-up on earth,” the company said in the filing. “We are a brand backed by a family tradition of a quarter of a millennium with the resilience, timeless relevance, and credibility of a multigenerational business.”
Facebook parent Meta is well aware of the efforts taken by counterfeiters on its platform. In 2021, Facebook and luxury brand Gucci filed a joint lawsuit in California, alleging that a user of Facebook’s U.S. sites was using the platform to sell fake Gucci products.
The companies said in a statement that over a million “pieces of content were removed from Facebook and Instagram in the first half of 2020, based on thousands of reports of counterfeit content from brand owners, including Gucci.”
In the six months ending March 31, Birkenstock’s revenue climbed 19% to 644.2 million euros, or $693.2 million. Net income over that stretch dropped 45%, largely due to a foreign exchange loss.

Google on Friday made the latest a splash in the AI talent wars, announcing an agreement to bring in Varun Mohan, co-founder and CEO of artificial intelligence coding startup Windsurf.
As part of the deal, Google will also hire other senior Windsurf research and development employees. Google is not investing in Windsurf, but the search giant will take a nonexclusive license to certain Windsurf technology, according to a person familiar with the matter. Windsurf remains free to license its technology to others.
“We’re excited to welcome some top AI coding talent from Windsurf’s team to Google DeepMind to advance our work in agentic coding,” a Google spokesperson wrote in an email. “We’re excited to continue bringing the benefits of Gemini to software developers everywhere.”
The deal between Google and Windsurf comes after the AI coding startup had been in talks with OpenAI for a $3 billion acquisition deal, CNBC reported in April. OpenAI did not immediately respond to a request for comment.
The move ratchets up the talent war in AI particularly among prominent companies. Meta has made lucrative job offers to several employees at OpenAI in recent weeks. Most notably, the Facebook parent added Scale AI founder Alexandr Wang to lead its AI strategy as part of a $14.3 billion investment into his startup.
Douglas Chen, another Windsurf co-founder, will be among those joining Google in the deal, Jeff Wang, the startup’s new interim CEO and its head of business for the past two years, wrote in a post on X.
“Most of Windsurf’s world-class team will continue to build the Windsurf product with the goal of maximizing its impact in the enterprise,” Wang wrote.
Windsurf has become more popular this year as an option for so-called vibe coding, which is the process of using new age AI tools to write code. Developers and non-developers have embraced the concept, leading to more revenue for Windsurf and competitors, such as Cursor, which OpenAI also looked at buying. All the interest has led investors to assign higher valuations to the startups.
This isn’t the first time Google has hired select people out of a startup. It did the same with Character.AI last summer. Amazon and Microsoft have also absorbed AI talent in this fashion, with the Adept and Inflection deals, respectively.
Microsoft is pushing an agent mode in its Visual Studio Code editor for vibe coding. In April, Microsoft CEO Satya Nadella said AI is composing as much of 30% of his company’s code.
The Verge reported the Google-Windsurf deal earlier on Friday.

Nvidia’s Jensen Huang sells more than $36 million in stock, catches Warren Buffett in net worth

Nvidia CEO Jensen Huang unloaded roughly $36.4 million worth of stock in the leading artificial intelligence chipmaker, according to a U.S. Securities and Exchange Commission filing.
The sale, which totals 225,000 shares, comes as part of Huang’s previously adopted plan in March to unload up to 6 million shares of Nvidia through the end of the year. He sold his first batch of stock from the agreement in June, equaling about $15 million.
Last year, the tech executive sold about $700 million worth of shares as part of a prearranged plan. Nvidia stock climbed about 1% Friday.
Huang’s net worth has skyrocketed as investors bet on Nvidia’s AI dominance and graphics processing units powering large language models.
The 62-year-old’s wealth has grown by more than a quarter, or about $29 billion, since the start of 2025 alone, based on Bloomberg’s Billionaires Index. His net worth last stood at $143 billion in the index, putting him neck-and-neck with Berkshire Hathaway‘s Warren Buffett at $144 billion.
Shortly after the market opened Friday, Fortune‘s analysis of net worth had Huang ahead of Buffett, with the Nvidia CEO at $143.7 billion and the Oracle of Omaha at $142.1 billion.
The company has also achieved its own notable milestones this year, as it prospers off the AI boom.
On Wednesday, the Santa Clara, California-based chipmaker became the first company to top a $4 trillion market capitalization, beating out both Microsoft and Apple. The chipmaker closed above that milestone Thursday as CNBC reported that the technology titan met with President Donald Trump.
Brooke Seawell, venture partner at New Enterprise Associates, sold about $24 million worth of Nvidia shares, according to an SEC filing. Seawell has been on the company’s board since 1997, according to the company.
Huang still holds more than 858 million shares of Nvidia, both directly and indirectly, in different partnerships and trusts.
