SMCI - Accounting & Capital Structure Concerns | Equity Insights

In our view, the cash conversion cycle of 146 days at 31 March 2026 is more representative of the underlying working capital model than the 54-day reading reported at 31 December 2025. The 54-day reading was supported by a USD 13.75bn accounts payable balance representing 104 days of cost of sales — consistent with end-of-period supplier financing facilities (reverse factoring) classified as trade payables rather than as financial debt. As that balance was paid down to USD 3.69bn (36 days, a standard commercial term) during the January–March quarter, the underlying capital intensity of the model emerged. Days inventory outstanding has now reached 108 days, accommodating the USD 39bn AI server backlog management cited in the 9 June 2026 capital announcement.

The financing of the working capital build in Q3 FY26 came from new borrowings, not operations. Funded debt increased by USD 3.9bn between 31 December 2025 and 31 March 2026: current lines of credit and term loans grew from USD 202m to USD 2.10bn, and non-current lines grew from USD 21m to USD 2.02bn. The Q3 FY26 10-Q discloses a USD 2.00bn JPMorgan revolving credit facility and a USD 1.77bn CTBC revolving credit facility put in place to support working capital. The previously disclosed USD 1.79bn Receivables Purchase Agreement remains in place but no receivables had been sold under it as of the filing date.

For peer context, Dell Technologies has historically operated with a negative cash conversion cycle (cash-positive working capital), Hewlett Packard Enterprise has operated at approximately 20–30 days, and Lenovo at 10–15 days. A 146-day CCC at the scale SMCI is now operating, in our view, places considerable pressure on the gross margin profile (Q3 FY26 GAAP gross margin: 9.94%; 9M FY26 GAAP gross margin: 8.18%) given the working capital intensity it implies.

The instrument mix is a step-change from FY25. The June 2025 convertible (USD 2.3bn, 2030 maturity, zero coupon, capped call hedged) was structured to minimise day-one dilution and was specifically described by management as “minimal dilution”. Twelve months later, the new package contains USD 3.25bn of pure common equity (USD 1.25bn underwritten + USD 2.0bn ATM) and USD 3.75bn of mandatory convertible preferred — an instrument that cannot be redeemed in cash and must convert into a variable number of common shares on 1 June 2029. There is no capped call protection on the mandatory preferred tranche. Stock fell approximately 10% in after-hours trading on the day of the announcement (9 June 2026).

The ATM programme is the most diagnostic element. An at-the-market equity programme is the lowest-quality form of equity capital because it implies the issuer cannot wait for a single marketed block at a negotiated discount, and instead sells stock continuously into the secondary market at prevailing prices. The programme is structured to begin no earlier than calendar Q3 2026, providing a window for market conditions to stabilise but committing the company to continuous dilution thereafter regardless of price action.

The mandatory convertible preferred tranche removes investor optionality on the dilution. Mandatory convertibles, unlike traditional convertible notes, do not give holders the right to redeem at par for cash — conversion into common stock is automatic at the scheduled settlement date. For the USD 3.75bn tranche this means approximately 92 million new common shares will be issued on or around 1 June 2029 regardless of the prevailing stock price or the company’s cash position. The accepted dilution is the cost of receiving cash in the current period.

The stated use of proceeds is component purchase for AI orders, but the arithmetic shows the raise covers only a fraction of the cited backlog. Management cited approximately USD 39bn in AI server orders received from 20+ customers in recent weeks. At the 9M FY26 GAAP gross margin of 8.2%, cost of goods sold for USD 39bn of revenue would total approximately USD 35.8bn. The USD 7.0bn equity raise therefore funds approximately 20% of the COGS required to deliver the cited backlog. The remainder must come from existing cash (USD 1.29bn at 31 Mar 2026, materially lower today), continued use of the USD 4.1bn drawn lines of credit, the USD 1.79bn Receivables Purchase Agreement (currently unused), and/or further capital raises.

Reading across the capital actions of the last twelve months tells a consistent story. In June 2025 management raised USD 2.3bn in zero-coupon convertibles with capped calls, framed as “minimal dilution”. In Q3 FY26 the company drew USD 4bn in new lines of credit. In June 2026 it has announced USD 7.0bn of equity-linked instruments dominated by straight common and mandatory preferred. The instrument mix has moved progressively along the dilution spectrum as the operating cash gap has widened.

We are not alleging that SMCI’s filings are fraudulent. BDO USA has issued clean opinions on the FY24 and FY25 financial statements. No prior financial statements have been restated. The Cooley LLP / Forensic Risk Alliance independent special committee found no evidence of fraud or misconduct in December 2024. The Department of Justice inquiry reported in September 2024 remains unresolved and unpublished as to outcome. This note expresses Lighthouse Canton’s concerns about accounting practices, cash conversion dynamics and capital structure; it does not assert that any law or accounting standard has been breached.

That said, the filings show what we view as a notably elevated cluster of accruals-based earnings quality indicators relative to US large-cap technology peers. A Sloan accrual ratio of approximately 46%, a cash conversion cycle that has tripled to 146 days once the supplier financing lever reversed, a 9M FY26 free cash flow gap of approximately USD 7.7bn against reported earnings of USD 1.05bn, three Beneish indicators at multiples of threshold, and a 9% gross margin against a 108-day inventory cycle define a profile the academic accounting literature associates with elevated earnings-quality risk.

The 9 June 2026 USD 7.0bn capital announcement, in our reading, is consistent with management’s own assessment of the operating funding gap. The mix shift — from capped-call-protected convertibles (FY25) to USD 3.25bn of straight common equity plus USD 3.75bn of mandatory convertible preferred plus a USD 2.0bn ATM (9 June 2026) — would not, in our view, be the chosen capital structure if the operating model could fund the working capital absorption required by the cited USD 39bn order backlog. The use of a mandatory convertible preferred specifically, with automatic conversion in June 2029 and without capped call protection, accepts a known and pre-committed dilution of approximately 13% on the current basic share count in exchange for current-period cash. The ATM tranche commits to continuous dilution from calendar Q3 2026 onward.

Taken together, the combination of (i) the 2020 SEC accounting violation finding under the same management team, (ii) the October 2024 resignation of a Big Four auditor, (iii) live material related-party contract manufacturing arrangements with family-controlled entities, (iv) a Sloan accrual reading in the historic top <1% percentile, (v) a 146-day cash conversion cycle, (vi) a 9% gross margin profile, and (vii) a USD 7.0bn equity-linked raise sized to fund only a fraction of the components for the stated backlog, forms the basis of Lighthouse Canton’s elevated concern around SMCI’s accounting practices and capital structure. We will continue to monitor disclosures and update our view as facts develop.
