Lightwave Logic Delays Volume Production to 2028 as Loss Widens

Lightwave Logic now expects volume production of its electro-optic polymer technology to begin in 2028, a delay from its previous goal of the second half of 2027. The company reported the revised timeline on its third-quarter earnings call for the period ended Sept. 30, alongside a net loss that widened to approximately $7.2 million, or 5 cents per share, from $5.1 million, or 4 cents per share, a year earlier.

President and CEO Yves LeMaitre attributed the pushback to longer silicon photonics wafer production schedules, extended process qualification cycles, and remaining customer development and product testing.

"The main challenge we have been facing in 2026 is a slower pace of Silicon Photonics Foundries, both in terms of production cycles and PDK process qualification," LeMaitre said, referring to the process design kits that support chip manufacturing.

What does the Foxconn demonstration show?

At Hon Hai Tech Day in Taipei in October, Foxconn — formally Hon Hai Technology Group — demonstrated an optical transceiver built around a silicon-organic hybrid optical engine enabled by Lightwave's polymer technology. The two companies began working together in the first half of 2025 and showed a first iteration of an optical engine capable of supporting 200 gigabits per second per lane.

LeMaitre described the Taipei demonstration as system-level evidence of how Lightwave's technology can be incorporated into a customer product. In plain terms: the polymer works inside a real device, not just a lab.

He cautioned that further chip design, integration, reliability testing, manufacturing preparation and customer-specific qualification remain before the program reaches volume production. Beyond Foxconn and Marvell, Lightwave has three other Fortune Global 500 customers in Stage 3 of its design-win process. The company defines Stage 4 as the point where technical and qualification requirements are met, commercial terms are agreed, and a customer's product is ready for volume manufacturing and shipment.

Where does the foundry pipeline stand?

Lightwave received wafers from two foundry partners during the third quarter. Chips from one partner powered the Foxconn transceiver demonstration, and additional wafers from that foundry should arrive by the end of 2026. A second partner hit process issues at one facility and delivered only a limited number of usable chips; it is expected to deliver two new sets of high-performance chips from different manufacturing locations in the first half of 2027.

The schedule beyond that is specific:

• Wafers from a third partner are expected in December 2026.
• A run with a fourth partner is tentatively scheduled for the first half of 2027.
• The active foundry ecosystem includes GlobalFoundries, Tower Semiconductor, SilTerra and an unnamed fourth partner.

LeMaitre said demand for silicon photonics production capacity is straining foundries and squeezing the resources and schedules available to qualify new materials and processes.

The company is also negotiating with a specialist in wafer-level optical manufacturing to scale back-end processing — depositing and preparing its polymer on silicon photonics chips. That work currently takes place in Denver, and Lightwave plans to outsource it as it pursues higher volumes and larger, 300-millimeter wafers. The shift from in-house to outsourced processing is the operational hinge for reaching scale.

What did the third-quarter numbers show?

Net sales rose to approximately $38,000 from $29,000 a year earlier, with roughly $100,000 in deferred revenue at quarter-end. CFO Fred Graffam said revenue remains limited and should be driven principally by technical and commercial milestones in existing development contracts.

Spending climbed across both major lines. Research and development expense increased to $4.3 million from $2.9 million, while general and administrative expense rose to $3.7 million from $2.3 million.

Cash, equivalents and marketable securities totaled approximately $87.8 million at Sept. 30, down from $95.9 million at June 30. Cash used in operating activities ran approximately $15 million for the first nine months of 2026, including $5.2 million in the third quarter. Graffam said the company believes it holds sufficient liquidity to fund its operating plan into 2028.

Does the delay change the strategy?

Graffam said the production delay does not fundamentally change the company's capital allocation approach. He also confirmed that negotiations over a second material supply and licensing agreement remain active, but declined to provide further details.

LeMaitre said development of both 200G-per-lane and 400G-per-lane solutions remains a priority, and the revised production timeline is not tied to any slowdown in next-generation research investment. The company views 200G as a stepping stone toward 400G, while applications beyond 400G may require different technology.

The takeaway for finance desks: a two-to-three-quarter production slip, a wider loss from stepped-up R&D, and a cash position management says stretches into 2028.
