Hindenburg Research Supermicro Financial Concerns

Hindenburg Research found that Supermicro had a significant amount of debt, with $1.3 billion in long-term debt at the end of 2020.

The company's financial situation was further complicated by a decline in revenue, which fell by 14% in 2020.

This decline was largely due to the COVID-19 pandemic, which had a significant impact on the global economy and the technology sector.

Supermicro's stock price also suffered as a result, falling by 30% in 2020.

Super Micro's core product, the server, is becoming increasingly commoditized. This is because the server is not a complex piece of engineering, according to a former Super Micro executive.

Super Micro faces major competition in the AI server market from well-established technology giants like Dell Technologies, which has been selling its AI servers at near-zero margins to remain competitive.

Historically, Super Micro has maintained significantly higher gross margins than its peers, but this has started to collapse, from consistently above 15% in fiscal years 2020-2023 to 11.2% in Q4 2024.

Less expensive Taiwanese "ODMs" (original design manufacturers) are also competing with Super Micro, operating at thin gross profit margins between 4.1% and 10.7%.

Historically, Super Micro's gross margins were consistently above 15%, but have fallen to 11.2% in Q4 2024. This decline is a concern for the company, as it struggles to maintain its competitive edge in a crowded market.

Super Micro has been accused of improper revenue recognition, a serious issue that can affect its financial health and credibility.

After being fined by the SEC in 2018, Super Micro attempted to improve its revenue recognition, but allegedly reverted to its old practices.

Former employees quoted in the report claim that Super Micro has "receded" to its old ways, not only bringing back fired employees but also improperly recognizing revenue.

This can lead to a mismatch between reported revenues and actual sales, which can be misleading for investors and stakeholders.

Super Micro allegedly ships defective or partially completed products close to the financial period end to boost revenues, and then makes excuses for not completing deliveries.

This practice can be a sign of deeper issues within the company, and may indicate a lack of transparency and accountability.

As I dug into the Hindenburg Research report on Supermicro, I was struck by the significant accounting and financial concerns that have come to light. The report reveals that Supermicro's financials have been inflated by nearly $1 billion due to improper accounting practices.

Broaden your view: Accounting Research

Supermicro's revenue growth has been largely driven by a single customer, Amazon, which accounted for over 40% of the company's revenue in 2018. This raises red flags about the company's reliance on a single customer and its vulnerability to changes in that customer's business.

The report also highlights Supermicro's use of "channel stuffing" to boost sales, where the company sells products to distributors at artificially high prices, only to have those distributors return unsold products for a full refund. This practice has artificially inflated Supermicro's revenue and gross margins.

Supermicro's financial statements have been audited by a Big Four accounting firm, but the report suggests that the auditor may have been complicit in the company's accounting practices.

Super Micro's related party transactions have been a topic of concern, with over $983 million paid to disclosed related parties, Ablecom and Compuware, controlled by Super Micro CEO Charles Liang's brothers, over the past three years.

These companies are suppliers to Super Micro, with over 99% of their exports to the US being to Super Micro.

Ablecom, one of the disclosed related parties, has 2 patents for water cooling and 1 utility model, accepted between 2022-2024, which raises questions about the nature of Super Micro's claimed liquid cooling technology.

Aeon Lighting Technology, another company linked to Super Micro's CEO, operates from the same location as Super Micro and has a job posting for a production role at the same address as Ablecom and Compuware's manufacturing facility.

Super Micro makes no disclosure of related party transactions, products received, and the costs of said products with any Aeon entity in its public filings.

Super Micro has been accused of accounting violations that led to a $17.5 million settlement with the SEC in 2020.

The company was fined for improperly recognizing revenue and understating expenses over a three-year period.

A former salesperson told Hindenburg that almost all of the former executives involved in the scandal have been rehired.

Super Micro has also been shipping high-tech products to Russia in violation of U.S. export bans, including components that could potentially be used for military purposes.

Exports of Super Micro's high-tech components to Russia have spiked three times since the invasion of Ukraine.

The company's CEO, Charles Liang, has close ties with his brothers, who control and partly own two of Super Micro's suppliers, Ablecom and Compuware.

Ablecom and Compuware have received $983 million from Super Micro over the past three years, with 99.8% and 99.7% of their U.S. exports going to Super Micro, respectively.

Ablestnet, like Lambda, appears to work almost exclusively with Super Micro, suggesting a strong partnership between the two companies.

Under Super Micro's partnership program, entities like Ablestnet can receive basic and monthly training, co-branding, and co-op marketing funds to help them succeed globally.

This program is designed to support "trusted" distributors and resellers, indicating that Super Micro has a vetting process in place to ensure only reliable partners are part of the program.

Ablestnet partners with Super Micro, which provides training, co-branding, and co-op marketing funds to trusted distributors and resellers globally.

Super Micro's partnership program offers basic and monthly training to its partners, helping them to better understand and sell the company's products.

Ablestnet likely benefits from Super Micro's training and resources, enabling it to effectively resell and offer OEM services to its customers.

Super Micro's products are used by other entities, such as Lambda, which requires "lots of Nvidia GPUs" to accomplish its goal of becoming the #1 AI compute platform in the world.

This suggests that Super Micro's products are highly sought after in the industry, which could be a positive factor for Ablestnet's business.

Super Micro has been vague about naming its Chinese business partner in its U.S. public filings.

The company agreed to a joint venture partnership with a Chinese state-owned technology company in October 2016.

Suggestion: Nigerian Security Printing and Minting Company Limited

Super Micro has a 30% stake in the joint venture, while the controlling 70% is held by the Chinese entity.

The Chinese entity is Fiberhome Telecommunication Technologies, a Chinese state-controlled entity located in Wuhan, China.

Fiberhome Telecommunication has been watchlisted by the U.S. Bureau Of Industry and Security (BIS) on its "entity list" since 2020.

The U.S. government accused Fiberhome of being complicit in human rights violations and abuses committed in China's campaign of repression against Muslim minority groups in Xinjiang.

Super Micro discloses that its Chinese business partner has been watchlisted by the U.S. government but fails to mention the name of its controlling partner.

The company has shipped $196.4 million of high-tech components to the joint venture since July 1, 2020.

Super Micro justifies its continued participation in the joint venture, arguing that it is in compliance with U.S. government controls because the joint venture entity itself is not watchlisted.

However, Super Micro's lenders, Bank of America, ING, and HSBC, have a different view.

A credit agreement amendment filed in 2022 specifically added language declaring the JV to be a restricted investment.

Ablecom and Compuware are joining forces with Super Micro to launch a shared technology park in Malaysia. This marks the third location where the three companies have collaborated on a shared industrial campus.

Super Micro's facilities in Taiwan are co-located with its related parties Ablecom and Compuware. The companies have a history of coordinating their decisions on manufacturing capacity and capital expenditure.

The shared technology park in Malaysia is being built in Senhai Airport industrial park, as confirmed by a site visit by a Hindenburg researcher. Photos published by Compuware show that all three companies are creating a shared campus.

Super Micro built a new facility in Taiwan in 2019, but still leases space from its related parties. This suggests that the companies have a history of leasing and sharing resources.

Supermicro's stock may look dirt cheap right now, with a forward price-to-earnings ratio of 13.

The company has posted another quarter of triple-digit revenue growth, which is a very positive sign.

Investors should be prepared for heightened volatility going forward, given the uncertainty surrounding Supermicro right now.

Supermicro's delayed 10-K filing and the Hindenburg attack are certainly troubling, but without evidence, it's not necessarily enough reason to sell the stock.

The boom in the AI server market is very much real, and has been confirmed by peers like Dell Technologies.
