Mobix Labs executed a 1-for-10 reverse stock split on April 6, 2026 to regain Nasdaq's minimum bid compliance (S-1/A). Its Risk Factors state there is "substantial doubt about our ability to continue as a going concern" (S-1/A). In the fiscal year ended September 30, 2025, sales to Leidos Holdings, Inc. accounted for approximately 50% of the Company's net revenues (S-1/A).

Mobix Labs, Inc. is an Irvine, California semiconductor company that designs mmWave 5G, RF, EMI-filter, and active optical cable components for consumer, industrial, medical, aerospace, and defense markets (S-1/A Summary). It already trades on Nasdaq under the symbol MOBX. On July 8, 2026, the last reported close was $2.06 per share (S-1/A cover). On July 9, 2026, it filed an S-1/A to register 3,744,161 Class A common shares for resale by selling stockholders; the Company itself will receive no proceeds from the resale and up to $6.0 million if the associated Preferred Warrant is cash-exercised (S-1/A cover).

The origin story

The current Mobix Labs entity is the surviving corporation of the December 21, 2023 business combination between Chavant Capital Acquisition Corp. and Legacy Mobix Labs (S-1/A Summary). At the closing, Chavant renamed itself Mobix Labs, Inc.; the operating business it acquired was renamed Mobix Labs Operations, Inc. (S-1/A). Class A Common Stock and Public Warrants began trading on Nasdaq under MOBX and MOBXW on December 22, 2023 (S-1/A).

In 2021, Legacy Mobix acquired substantially all assets and IP of Cosemi, an Irvine-based active optical cable supplier that became the foundation of the current connectivity business (S-1/A Summary). Post-merger, Mobix acquired RaGE Systems, Inc.; its earnout structure produced 464,952 of the shares now being registered for resale (S-1/A The Offering).

Stockholders approved a reverse stock split at a special meeting held March 23, 2026; the board selected a 1-for-10 ratio and the split took effect after market close on April 6, 2026 (S-1/A Recent Developments). Compliance with Nasdaq's $1 minimum bid requirement was regained on April 21, 2026 (S-1/A Risk Factors).

What could break

The Risk Factors state directly: "we may not achieve or maintain profitability and there is substantial doubt about our ability to continue as a going concern" (S-1/A Risk Factors).

Customer concentration is severe. In the fiscal year ended September 30, 2025, sales to Leidos Holdings, Inc. accounted for approximately 50% of net revenues; no other customer accounted for 10% or more (S-1/A Risk Factors). The filing states: "The loss of this customer would have a material adverse impact on our results of operations and financial condition" (S-1/A Risk Factors).

Nasdaq re-delisting risk is specifically disclosed. Nasdaq rules provide that a listed company that fails to meet the Minimum Bid Price Requirement "and has effected a reverse stock split over the prior one-year period... will not be eligible for an automatic 180-day grace compliance period and the Staff is obligated to immediately issue a delisting determination" (S-1/A Risk Factors).

The filing also discloses material weaknesses in internal control over financial reporting, including that the Company "did not design and maintain effective IT general controls" (S-1/A Risk Factors).

The offering

This is a resale registration, not a primary offering. The S-1/A registers up to 3,744,161 Class A shares for selling stockholders: 2,000,000 issuable on conversion of the Series A 10% Convertible Preferred Stock and its Preferred Warrant, 1,207,942 issued to settle debt owed to lenders, 71,267 issued to settle litigation, and 464,952 as RaGE Systems earnout (S-1/A The Offering). The Company receives no resale proceeds and up to $6.0 million if the Preferred Warrant is cash-exercised, for working capital and general corporate purposes (S-1/A Use of Proceeds). No underwriter is listed; selling stockholders bear their own commissions (S-1/A).

What to watch

  • Vision Aerial acquisition: the Risk Factors disclose a non-binding letter of intent to acquire Vision Aerial, Inc., and note that any such acquisition "is subject to significant uncertainty and may require additional dilutive financing" (S-1/A Risk Factors).
  • Nasdaq compliance status: with the 1-for-10 reverse split executed April 6, 2026, any subsequent failure to meet the minimum bid requirement is not eligible for the automatic 180-day grace period per Nasdaq rules (S-1/A Risk Factors).
  • Leviston convertible note: on March 31, 2026 the Company entered into a securities purchase agreement with Leviston for a senior secured convertible promissory note with a principal amount of $3 million; a first amendment was executed May 13, 2026 (S-1/A Recent Developments).
  • Preferred Warrant exercise: full cash exercise brings up to $6.0 million to the Company (S-1/A The Offering).
  • Earnout share issuance: 350,000 Class A shares remain issuable to certain Legacy Mobix stockholders and option holders based on trading-price targets during a seven-year earnout period (S-1/A The Offering).
