Nikola Corporation

Nikola’s 2025 10-K is the kind of document where, if you set out to engineer a forensic-accounting case study from scratch, you would probably end up with something less on-the-nose. The MD&A devotes seventeen pages to “going-concern considerations” before mentioning revenue, which the company forthrightly admits has a “limited” base — a useful adverb for $35M of trucks the auditors then discounted for “shipment-not-recognized” complications.

The Beneish M-Score (−1.42) and Altman Z″ (1.18) tell broadly the same story in different dialects: receivables are growing faster than sales, gross margins keep eroding, and working capital has gone negative for the third year running. None of these are individually fatal. Together they describe a company whose accounting choices have been bending in one direction for long enough that bending back would itself be news.

The Piotroski F-Score of 3/9 is, in fairness, a noisy signal for a business that hasn’t yet earned a positive operating margin in any quarter — but it is a signal. Three of the nine criteria measure leverage and liquidity trends, and all three flag negatively. The Fog Index of 19.4 is the editorial half of this: the average sentence in the risk factors section runs 31 words and contains 2.4 clauses, which is what people mean when they say a filing is hard to read on purpose.

None of this answers the question of whether NKLA the security is mispriced — that question requires a view on hydrogen infrastructure, federal credits, and the patience of the remaining lenders. It does answer the narrower question of whether the filing itself reads like the management team is trying to be understood. It does not. Read the 10-K. Decide for yourself. Then come back and tell us why we’re wrong.
