Vicor Corporation Reports Results for the First Quarter Ended March 31, 2021

Andover, MA, April 22, 2021 (GLOBE NEWSWIRE) — Vicor Corporation (NASDAQ: VICR) today reported financial results for the first quarter ended March 31, 2021. These results will be discussed later today at 5:00 p.m. Eastern Time, during management’s quarterly investor conference call. The details for the call are presented below.

Revenues for the first quarter ended March 31, 2021 totaled $88.8 million, a 40.1% increase from $63.4 million for the corresponding period a year ago, and a 5.3% sequential increase from $84.3 million the fourth quarter of 2020.

Gross margin increased to $44.7 million for the first quarter of 2021, compared to $27.3 million for the corresponding period a year ago, and increased sequentially from $40.5 million for the fourth quarter of 2020. Gross margin, as a percentage of revenue, increased to 50.3% for the first quarter of 2021, compared to 43.1% for the corresponding period a year ago, and increased from 48.0% for the fourth quarter of 2020.

Net income for the first quarter was $15.1 million, or $0.34 per diluted share, compared to a net loss of ($1.7) million or ($0.04) per share, for the corresponding period a year ago and net income of $11.2 million, or $0.25 per diluted share, for the fourth quarter of 2020.

Cash flow from operations totaled $17.6 million for the first quarter, compared to cash used for operations of $0.9 million for the corresponding period a year ago, and cash flow from operations of $19.3 million in the fourth quarter of 2020. Capital expenditures for the first quarter totaled $9.3 million, compared to $3.0 million for the corresponding period a year ago and $11.8 million for the fourth quarter of 2020. The sum of cash, cash equivalents, and short-term investments sequentially rose 5.3% to approximately $223.1 million compared to the fourth quarter of 2020.

First quarter bookings increased 41.2% to $98.9 million, from $70.1 million for the corresponding period a year ago, and increased sequentially 8.1% from $91.5 million for the fourth quarter of 2020. Total backlog at the end of the first quarter of 2021 was $157.1 million, up 6.5 % from $147.6 million at the end of 2020.

Commenting on first quarter performance, Dr. Patrizio Vinciarelli, Chief Executive Officer, stated, “Q1 revenues and gross margins reflected strong demand and improved manufacturing efficiencies. Vertical integration of power packaging processes and increased capacity in expanded facilities will enable greater revenue and margin growth starting in 2022. For the balance of 2021, sequential quarterly increases in revenue are capacity constrained to 7% while bookings and backlog are expected to grow at a faster pace.”

Dr. Vinciarelli concluded, “While 48V adoption in data centers is accelerating, current requirements for lower voltage rails feeding AI processors are stepping up nearly 2X every 2 years. Vicor’s power system modules are uniquely fit to support this trajectory, prompting OEMs seeking to advance their AI solutions to gain preferential access to Vicor’s enabling technology.”
