Executive summary

LightWave Logic Q2 FY26 — Advancing Commercialization with Foundry Progress and New Stage 3 Customer

Lightwave Logic is progressing from technology development to commercialization, driven by strong AI demand for optical interconnects. The company is focused on advancing its electro-optic polymer technology through multiple foundry engagements and expanding its Stage 3 customer programs, with initial wafer deliveries and testing expected soon. Despite increasing operating expenses and net losses, a strong balance sheet provides financial flexibility to support future growth and a targeted production ramp in H2 2027.

Highlights

5
  • Expanded to five Stage 3 customers, including a new Fortune Global 500 customer, indicating strong interest and concrete engineering work.

  • Made good progress with multiple foundry engagements, with first wafers expected this month (August 2026) from two foundries, and a third in Q4.

  • Maintained a strong balance sheet with $95.9 million in cash, cash equivalents, and marketable securities at quarter-end.

  • Increased headcount by 25% sequentially, particularly in manufacturing scale-up, test engineering, and commercial development.

  • One material supply and licensing agreement is already in place, with active negotiations for a second.

Concerns

4
  • Net loss increased to $6.6 million in Q2 FY26 from $5 million in Q2 FY25.

  • Cash used in operating activities increased to $9.9 million in H1 FY26 from $7.3 million in H1 FY25.

  • Foundry ecosystem still faces pressures from strong demand, process development for novel materials, and capacity investment needs.

  • Revenue for the quarter was only $33,000, indicating a very early commercialization stage.

Deals & partnerships

Unnamed Material supply and licensing agreement

One such agreement is already in place.

Unnamed (customer furthest along to productization) Negotiation for a new material supply and licensing agreement

Actively negotiating a new agreement with another customer whose program is the most advanced on the path to productization.

Risks & headwinds

Foundry ecosystem pressures (capacity, process development, yield learning, packaging, test availability) Ongoing

Global Foundries communication infrastructure and data center business grew >60% YoY; Tower Semiconductor silicon photonics revenue grew >270% YoY.

Mitigation:Lightwave Logic is working with four foundry partners to reduce risk and build process knowledge, aiming for repeatable polymer integration. They are also working on outsourcing BEOL integration for high-volume production.

Programs take time due to foundry schedules, design changes, packaging, and system testing. Ongoing

Not quantified.

Mitigation:Focus on doing the work, meeting the next milestone, and earning the right to move each program forward.

What to watch in Q3 FY26

Wafer Delivery (First Two Foundries)

Q3 FY26 (August 2026)
Current Expected in August 2026
Target Successful delivery and start of back-end processing/testing

Why it matters

This is a critical milestone for advancing technology and supporting customer programs, leading to clearer technical pictures and next decisions with customers.

We expect to receive two sets of wafers from those programs during this month of August.

Q&A highlights

What are the biggest bottlenecks in the foundry ecosystem (capacity, process development, yield, packaging, test)?

Yves LeMet explained that foundries face pressure from increasing capacity, new production sites, 300mm wafer transition, and integrating new materials like electro-optic polymers. He also highlighted the "back end of line" (BEOL) integration of perkinamine on silicon photonics chips, which is currently in-house but being outsourced for high-volume production with a lead customer for a scalable production line.

“We are working with one of our lead customers to build a scalable back-end production line so we can scale the production across all aspects of the final product, the perkinamine production. front-end silicon photonics production and the back-end of line process.”

Detailed narrative

AI Bottlenecks and Optical Interconnects

The AI industry faces significant bottlenecks in compute, memory, interconnect bandwidth, power, and cooling. Lightwave Logic is focused on addressing the interconnect problem, where optical networking and silicon photonics are becoming critical for scaling AI infrastructure due to the limitations of copper. Industry leaders like Global Foundries and Tower Semiconductor are reporting substantial year-over-year growth in optical networking and silicon photonics revenue, underscoring the rapid mainstream adoption of these technologies in AI infrastructure.

Perkinamine Technology and Foundry Ecosystem

Lightwave Logic's perkinamine electro-optic polymers are designed to enhance silicon photonics with faster speeds, greater power efficiency, and smaller footprints, while integrating seamlessly into existing foundry and packaging infrastructure. The company currently has three dedicated foundry runs in progress, with wafers anticipated from two in August 2026 and from the third in Q4 2026. Additionally, a fourth foundry partner is being prepared for a tape-out later this year, establishing a robust, multi-foundry approach to ensure scalability and customer flexibility.

Progress with Stage 3 Customers

Lightwave Logic has successfully expanded its Stage 3 customer programs to five, including the addition of a new Fortune Global 500 customer. This new program is specifically focused on scale-across transceivers utilizing coherent modulation, a critical component for next-generation AI factories. Stage 3 involves concrete engineering work, prototype development, foundry runs, and device testing. The immediate objective is to achieve technical milestones necessary for qualification, with expected wafer deliveries and subsequent testing in Q4 2026.

Commercialization and Production Readiness

In parallel with technical advancements, Lightwave Logic is actively developing its commercial framework. One material supply and licensing agreement is already in effect, and negotiations are underway for a second agreement with the most advanced customer, with a goal of initiating volume production in H2 2027. The company is also enhancing its operational readiness for a potential production ramp in 2027, including expanding perkinamine production capabilities in Denver through new staff training and equipment commissioning.

Financial Position and Strategic Investments

Lightwave Logic concluded Q2 FY26 with a strong financial position, holding $95.9 million in cash, cash equivalents, and marketable securities, which provides substantial flexibility for strategic initiatives. The company continues to make targeted investments in research and development ($3.9 million, up from $2.6 million YoY) and general and administrative expenses ($3.4 million, up from $2.3 million YoY) to further technology, expand intellectual property, integrate the foundry ecosystem, and support commercialization efforts. Capital expenditures for H1 FY26 totaled $1.5 million, primarily directed towards production readiness and IT infrastructure.
