ALT5 Sigma Corporation has notified the SEC that it will be late in filing its Form 10-K (Yearly Report) for the fiscal year ended December 27, 2025, via a Form 12b-25. The delayed filing concerns the company’s Annual Report on Form 10-K (Yearly Report), which covers its most recent full-year results.
The company cites the need for additional time to finalize its annual financial statements tied to accounting for an acquisition completed during the year. It also points to delays from a previously announced change in its PCAOB-registered public accounting firm, which has extended the audit process.
ALT5 Sigma says it expects to submit the Form 10-K (Yearly Report) on or before April 13, 2026, making use of the standard 15-calendar-day extension permitted under SEC Rule 12b-25. Investors should therefore anticipate the annual report within this grace period unless further issues arise.
The company has flagged that it expects a significant change in results, projecting a net loss between $340 million and $345 million for the 2025 fiscal year. These figures are preliminary and forward-looking, and the final audited results in the Form 10-K (Yearly Report) may differ once the accounting and audit work is fully completed.
ALT5 Sigma notes that it has filed all other required periodic reports over the past 12 months and is working to complete the current filing in compliance with SEC rules. The notification was signed on March 27, 2026, by Acting Chief Executive Officer Tony Isaac, underscoring management’s responsibility for the disclosure and ongoing reporting obligations.
The most recent analyst rating on (ALTS) stock is a Hold with a $2.00 price target. To see the full list of analyst forecasts on ALT5 Sigma Corporation stock, see the ALTS Stock Forecast page.
Spark’s Take on ALTS Stock
According to Spark, TipRanks’ AI Analyst, ALTS is a Neutral.
The score is held back primarily by weak core operating performance and negative TTM cash flow despite improved revenue, suggesting cash burn risk. Technicals are only mildly supportive in the near term but remain weak over longer timeframes. Valuation is constrained by a negative P/E and no dividend support, while corporate events are mixed with added governance/financing positives offset by filing delay and legal/data-breach risk.
