Material control weaknesses
What was disclosed. The S-1 says "We identified material weaknesses in our internal control over financial reporting" (S-1/A). Secondary readings of the full risk factor give these details (Rajgopal, Forbes):
| # | Weakness | Areas affected |
|---|---|---|
| 1 | Not enough accounting personnel or technical expertise. This led to untimely account reconciliations and weak GAAP application. | Revenue recognition, inventory, data-center asset accounting, equity administration |
| 2 | Ineffective IT general controls, including segregation of duties | Systems behind the financials |
- Both weaknesses were present in FY2024 and FY2025 and were not remediated at IPO. Remediation is "underway," but testing of operating effectiveness was not complete.
- The auditor changed from BDO to KPMG in November 2025, partway through the year under audit. No disagreements were reported, and both years received clean (unqualified) opinions.
- Rajgopal notes the filing describes no internal audit function.
Why these matter more than usual. Material weaknesses are common at IPO; KPMG found them in 40–58% of 2021–23 US IPOs (cited by Forbes). What sets Cerebras apart is where the weaknesses sit relative to how complex its accounting is:
- Revenue recognition is the hardest area here. Cerebras mixes hardware sales, cloud and inference services and data-center builds. It also has the OpenAI Master Relationship Agreement: a >$20B, 750 MW commitment, a warrant for ~33.4M shares at a nominal strike, and a $1B working-capital loan that becomes callable if the agreement is terminated (S-1/A, Forbes). Warrant-linked customer deals call for judgment on contra-revenue and timing, which is exactly the expertise weakness #1 says is lacking.
- Related-party concentration. G42 and MBZUAI are related parties to each other under ASC 850. Together they were 86% of 2025 revenue, and MBZUAI alone was 77.9% of year-end receivables (S-1/A). Arm's-length pricing is asserted but hard to verify from outside (Rajgopal).
- Large non-cash items. A $363.3M non-cash gain from extinguishing the G42 forward contract (after CFIUS review stalled G42's investment) turned a $75.7M non-GAAP loss into $237.8M of GAAP net income (Forbes).
- Tone at the top. CEO Andrew Feldman pled guilty in 2007 to one count of circumventing accounting controls at Riverstone Networks and settled a related SEC civil matter. He is also chairman. Class B shares carry 20 votes each, and the board is classified with supermajority protections (Rajgopal). Rajgopal stresses that the 2007 matter has limited predictive power. His concern is that the oversight design leaves outside holders little recourse.
Practical implications: there is a higher risk of restatements, late filings or adverse SOX 404 outcomes as reporting obligations phase in. Expect remediation costs (accounting hires, ERP and ITGC work). Things to watch: each 10-Q/10-K's remediation update, any new weakness, and a disclosed internal audit function.
