Mobix Labs (MOBX): Customer Relationships That Drive Both Growth and Concentration Risk

Mobix Labs monetizes by selling high-performance hardware components—notably electromagnetic interference (EMI) filtering products and custom filtered connectors—plus engineering services for wireless and RF systems to OEMs in aerospace, defense and healthcare. Revenue comes from product sales through direct OEM channels, regional manufacturers’ representatives and global distributors, supplemented by engineering services contracts; financing partnerships provide balance-sheet flexibility. For investors, the company’s customer mix offers strong strategic validation in defense and medical markets while simultaneously concentrating revenue risk with a small number of large buyers.

How to read Mobix’s customer book: concentrated, industry-focused, and operationally tight

Mobix runs a mixed hardware-and-services business: product sales to equipment manufacturers are the primary revenue engine, with engineering services as a meaningful adjunct. Contracts are largely short-term, but product lifecycles in military, aerospace and healthcare can extend for years, producing long tail revenue on a successful design. The company’s sales footprint is U.S.-heavy, and its revenue base is highly concentrated—company filings for the year ended September 30, 2025 show one customer (Leidos) accounted for roughly 50% of net revenues, while prior-year filings show a single customer representing ~40% of revenue, and accounts receivable concentrated across two customers in different periods. Those figures indicate high dependency on a few large buyers, increasing both cash-flow volatility and negotiation leverage for large customers. These characteristics—short formal contract terms, potential for long in-production lifecycles, and customer concentration—define Mobix’s operating constraints as much as its opportunities.

Relationship-by-relationship: who buys from Mobix and why it matters

Below are every customer- or partner-related relationship surfaced in public reports and news; each entry is followed by a concise source note.

PerkinElmer

Mobix began selling proprietary EMI filtering products to PerkinElmer for integration in pharmaceutical diagnostics and digital imaging solutions, positioning Mobix in the medical-imaging supply chain. According to the company’s second-quarter 2024 press release (Business Wire, May 14, 2024) https://markets.financialcontent.com/wss/article/bizwire-2024-5-14-mobix-labs-inc-announces-second-quarter-2024-financial-results.

GE HealthCare

Mobix expanded into GE HealthCare with proprietary electromagnetic filters intended for diagnostic and digital imaging applications, giving the company access to a large OEM in healthcare equipment. This relationship is described in the same Q2 2024 company release (Business Wire, May 14, 2024) https://markets.financialcontent.com/wss/article/bizwire-2024-5-14-mobix-labs-inc-announces-second-quarter-2024-financial-results.

Arrow Electronics

Mobix signed a global distribution agreement with Arrow Electronics to place EMI filtering products through Arrow’s channels, with an initial focus on defense and aerospace markets—an immediate scale play via an established electronics distributor. The agreement was announced in Mobix’s May 14, 2024 release (Business Wire) https://markets.financialcontent.com/wss/article/bizwire-2024-5-14-mobix-labs-inc-announces-second-quarter-2024-financial-results.

Gulfstream Aerospace Corp. (sole-source supplier)

Mobix is the sole-source supplier of custom filtered connectors used by Gulfstream Aerospace, a direct signal of product criticality to a complex OEM supply chain and a potential multi-year revenue stream tied to aircraft programs. This sole-source designation is described in the May 14, 2024 company release (Business Wire) https://markets.financialcontent.com/wss/article/bizwire-2024-5-14-mobix-labs-inc-announces-second-quarter-2024-financial-results.

Gulfstream (purchase orders supporting current production)

In a separate update, Mobix confirmed new Gulfstream purchase orders that support ongoing aircraft production, showing the commercial continuation of that OEM relationship into FY2026. The procurement update was reported by BDtonline in a FY2026 article summarizing recent purchase orders and production-linked demand https://www.bdtonline.com/news/nation_world/mobix-labs-receives-new-gulfstream-aircraft-component-orders-as-production-continues/article_559e00b6-4b72-5436-8d83-117f0df69a47.html.

BAE Systems

Mobix earned a Gold Tier supplier award from BAE Systems’ Electronic Systems sector for the second consecutive year—an operational validation that supports further defense contracting credibility and supplier performance signaling. The award and tier recognition were reported by Quiver Quant in a FY2025 note on supplier awards https://www.quiverquant.com/news/Mobix+Labs%2C+Inc.+Achieves+Gold+Tier+Supplier+Award+from+BAE+Systems+for+Second+Consecutive+Year.

MMS Technical Sales, Inc.

Mobix appointed MMS Technical Sales as a manufacturer representative for EMI filtering products across New England and Upstate New York, reflecting a deliberate regional go-to-market strategy to capture OEM and contract-manufacturer opportunities. This regional representation arrangement was announced in Mobix’s May 14, 2024 press release (Business Wire) https://markets.financialcontent.com/wss/article/bizwire-2024-5-14-mobix-labs-inc-announces-second-quarter-2024-financial-results.

B. Riley Principal Capital II, LLC

B. Riley committed to an equity purchase facility—up to $100 million of Class A common stock, subject to conditions—providing a liquidity and capital buffer that can fund production scale or working capital without near-term operating revenue changes. The committed equity facility was disclosed in a March 19, 2024 announcement (markets.financialcontent.com) https://markets.financialcontent.com/wss/article/bizwire-2024-3-19-mobix-labs-secures-100-million-committed-equity-facility.

What these relationships imply for investors

  • Concentration risk is real and measurable. Filings show one customer accounted for ~50% of revenue in FY2025; large receivable concentrations followed in prior years. That creates material revenue and cash-flow exposure if any of the major customers reduce orders.
  • Sole-source supplier status and multi-year production ties improve predictability for specific programs. Gulfstream sole-source and subsequent purchase orders indicate program-level revenue durability, offsetting some short-term contract exposure.
  • Channel agreements scale reach but dilute control. The Arrow global distribution deal opens defense and aerospace channels quickly, while regional reps (MMS) enable targeted OEM coverage—both expand go-to-market without heavy fixed-cost expansion.
  • Supplier recognition matters in defense procurement. BAE Systems’ Gold Tier award is a strategic credential that supports retention and expansion across defense OEM programs.
  • Capital support reduces near-term liquidity pressure but is dilutive. The B. Riley committed facility provides optionality for growth and working capital at the cost of potential share issuance.

For investors who evaluate supplier concentration, contract structure and program exposure, Mobix presents a classic high-conviction / high-concentration profile: strong technical validation and privileged OEM access, balanced by outsized dependency on a handful of customers. If you track supplier awards, distribution deals and sole-source acknowledgements, Mobix’s public disclosures show meaningful traction in defense, aerospace and healthcare channels.

Bottom line: balance technical wins against customer concentration

Mobix has established important commercial relationships—global distribution with Arrow, design wins with Gulfstream, PerkinElmer and GE HealthCare, and supplier recognition from BAE—that validate product-market fit in high-value segments. At the same time, filings demonstrate material revenue concentration and U.S.-centric sales that increase execution and counterparty risk. For portfolio managers and operators, the investment thesis rests on whether Mobix can convert distribution and supplier credentials into a broader, more diversified revenue base without excessive dilution.
