Lumentum (NASDAQ:ON) announced the appointment of Thad Trent to its Board of Directors, effective December 15, 2025, expanding the board to nine members.

Trent currently serves as Executive Vice President and Chief Financial Officer of onsemi (NASDAQ:ON) since February 2021 and brings stated expertise in corporate finance, M&A, in-house manufacturing and process efficiency. Lumentum leadership said his experience will support execution of the company's long-term strategy and efforts to capture opportunities in AI and cloud infrastructure markets.

onsemi (Nasdaq: ON) and FORVIA HELLA extended their strategic collaboration with a new long-term agreement to adopt onsemi’s PowerTrench® T10 MOSFET technology across FORVIA HELLA’s advanced automotive platforms, announced Dec. 11, 2025.

The T10 MOSFETs, produced at onsemi’s East Fishkill, NY facility, are described as offering ultra-low conduction and switching losses, higher power density in a compact footprint, reduced output capacitance, and lower drain-to-source resistance and gate charge—aimed at improving efficiency, reliability, and system cost for electrified and software-defined vehicle architectures.

onsemi (NYSE:ON) signed a memorandum of understanding with Innoscience to evaluate scaling production of GaN power devices (40–200V) using Innoscience’s 200mm GaN-on-silicon process and onsemi’s systems, drivers and packaging expertise. The collaboration aims to accelerate worldwide, high-volume deployment, lower system cost, and broaden adoption across industrial, automotive, telecom infrastructure, consumer and AI data center markets.

The non-binding MoU targets a projected $2.9 billion GaN power market by 2030 and expects sampling to begin in H1 2026.

onsemi (Nasdaq: ON) announced a new $6 billion share repurchase authorization covering a three-year period that launches on January 1, 2026 and expires on December 31, 2028. The program follows a prior $3 billion authorization that expires December 31, 2025; under that prior authorization the company repurchased $2.1 billion of common stock over the last three years.

The release says onsemi spent approximately 100% of its free cash flow in 2025 on repurchases, and that repurchases may occur via open-market purchases, privately negotiated transactions or Rule 10b5-1 trading plans. The authorization may be suspended or discontinued and does not obligate the company to repurchase any specific amount.

Non-GAAP operating margin was 19.2%. Cash from operations was $418.7M and free cash flow was $372.4M (22% YoY, 24% of revenue). Year-to-date share repurchases totaled $925M, roughly 100% of free cash flow. Segment revenue: PSG $737.6M (+6% QoQ, -11% YoY), AMG $583.3M (+5% QoQ, -11% YoY), ISG $230.0M (+7% QoQ, -18% YoY).

The company provided Q4 2025 guidance: revenue $1,480–$1,580M; GAAP diluted EPS $0.56–$0.66; diluted shares ~405M.

onsemi (ON) on Oct. 30, 2025 introduced vertical gallium nitride (vGaN) power semiconductors built on proprietary GaN-on-GaN technology. The company says vGaN conducts current vertically to enable higher operating voltages, faster switching and higher power density for AI data centers, EVs, renewables and aerospace.

Key disclosed facts: sampling of 700V and 1,200V devices to early access customers, development and manufacturing at onsemi's Syracuse fab, and a portfolio of 130+ patents. The company reports losses can be reduced by almost 50% and vGaN devices are ~three times smaller than lateral GaN.

onsemi (NYSE:ON) announced on October 28, 2025 that Teledyne Technologies selected its Treo platform to develop next‑generation readout integrated circuit (ROIC) ASICs for infrared focal plane array systems.

Treo is built on an advanced 65nm node with a modular architecture and IP library, and its ROIC process adds precision analog, advanced digital, low‑voltage power, and dense on‑chip energy storage. Key technical features cited include higher gate density, lower power dissipation, die stitching for large sensors, wide temperature operation (cryogenic to automotive grades), and low resistivity substrates for radiation resilience.

The platform is manufactured at onsemi’s East Fishkill, NY facility, which holds Category 1A Trusted Supplier accreditation to support U.S. government domestic chip needs.

onsemi (Nasdaq: ON) completed the acquisition of rights to Vcore power technologies and associated IP licenses from Aura Semiconductor on Oct 27, 2025. The deal expands onsemi's power-management portfolio and roadmap to address the full grid-to-core power tree for AI data center applications. Integration of Vcore technologies plus onsemi's silicon and silicon carbide (SiC) expertise aims to accelerate scalable designs for solid state transformers, power supply units, 800 VDC distribution, and core power delivery. With these combined capabilities, onsemi says it will be among a small set of companies able to meet stringent power requirements of modern AI infrastructure.

onsemi (Nasdaq: ON) will announce third quarter financial results for the period ended October 3, 2025 before the market opens on Monday, November 3, 2025.
