Management Commentary

  • CEO on 5G inflection: “We are happy to report that we are now at the one yard line when it comes to the sampling of our 5G chipsets… we will finally be in the position to benefit from… the upcoming release and shipment of our 5G chipsets” .
  • Partnerships to drive adoption: Highlighted collaborations with Globalstar, European Tier 1, Aramco Digital, Samsung, and Kyocera to accelerate development and mass production .
  • CFO on capital and debt: “We managed to reduce our debt by close to 50% during 2024… we remain in advanced discussion with potential investors to fill some of our near term capital funding needs” .

Q&A Highlights

  • Product/platform mix clarification: Q4 had “no platform sales,” with $0.66M product revenue primarily from 4G LTE chips; this explains sequential margin and revenue pressure vs Q3 .
  • 2025 ramp cadence: Near-term 2025 contributions to come from FWA, mobile hotspot, and legacy 4G customers converting to 5G; Aramco Digital likely more of a 2026 contributor .
  • Cash burn trajectory: Q4 operating cash burn of ~$2.3M; expected similar in Q1 2025, with improvement as 5G samples ship and ramp through H2 2025 .
  • Breakeven framework: Adjusted EBITDA breakeven still modeled around ~$25M revenue given margin targets; unchanged from prior views .

Estimates Context

  • S&P Global consensus for Q4 2024: Revenue $2.031M (1 estimate) and EPS $(0.15) (1 estimate). Actuals: Revenue $1.785M and EPS $(0.11), yielding a revenue miss and EPS beat. Expect analysts to adjust near-term revenue/margin assumptions to reflect the absence of Q4 platform sales and a back-half-weighted 2025 ramp .

Key Takeaways for Investors

  • The Q4 print was soft on revenue/mix and margin given no platform sales, but the EPS beat vs consensus underscores disciplined cost control and sequential progress on losses .
  • The near-term stock narrative hinges on 5G sampling and initial customer uptake; management’s “Year of 5G” program and partner roster provide credible commercialization pathways .
  • Balance sheet actions (debt reduction, maturities rolled forward) and external financing plans reduce execution risk ahead of the H2 2025 ramp; monitor shelf/ATM usage .
  • 4G remains a steady contributor with the new 7243SL supporting industrial/satellite use cases, but the growth lever is 5G ASPs multiple times higher than 4G .
  • Model implications: Maintain ~$25M revenue as adjusted EBITDA breakeven threshold; expect estimates to shift toward H2 2025 with margin uplift tied to 5G mix .
  • Watch for additional customer disclosures (FWA/mobile hotspot) and timeline clarity; Aramco Digital appears to be a 2026 driver rather than 2025 .
  • Near-term catalysts: formal sampling commencement, follow-on partner wins, financing announcements, and any early shipment indicators, which can drive sentiment and re-rate the path to scale .
