Gross margin, as a percentage of revenue, decreased to 47.2% for the first quarter of 2025, compared to 53.8% for the corresponding period a year ago, and decreased from 52.4% for the fourth quarter of 2024. Operating expenses decreased to $44.5 million for the first quarter of 2025, compared to $61.2 million for the corresponding period a year ago, and increased sequentially from $41.2 million for the fourth quarter of 2024.

Net income for the first quarter was $2.5 million, or $0.06 per diluted share, compared to a net loss of ($14.5) million or ($0.33) per diluted share, for the corresponding period a year ago and net income of $10.2 million, or $0.23 per diluted share, for the fourth quarter of 2024.

Capital expenditures for the first quarter totaled $4.6 million, compared to $7.3 million for the corresponding period a year ago and $1.7 million for the fourth quarter of 2024.

Commenting on first quarter performance, Chief Executive Officer Dr. Patrizio Vinciarelli stated: “Revenues and gross margins declined sequentially, with reduced income from a licensee transitioning to a new generation of unlicensed products. Margin improvements await higher utilization of our ChiP fab and increased income from existing and future licensees. Licensing has been gaining traction with OEMs and hyper-scalers wishing to avoid infringing hardware being excluded from importation into the US.”

“Our 2^nd generation VPD for leading AI applications is coming to fruition with the arrival of an ASIC raising the density and bandwidth of our current multipliers. Second generation VPD will enable AI processors setting new standards for performance. We are still focused on completing initial delivery of a very high density VPD system to a lead customer before providing demo systems to processor chip companies and hyper-scalers.”
