Silicom Reports Record Annual Results: $150.6M Revenues
with $3.12 Non-GAAP EPS

- 2022 Revenues Up 17% and Non-GAAP EPS Up 55% –

KFAR SAVA, Israel, January 30, 2023 - Silicom Ltd. (NASDAQ: SILC), a leading provider of high-performance networking and data infrastructure solutions, today reported its financial results for the fourth quarter and full year ended December 31, 2022.

Financial Results

Full Year: Silicom’s revenues for 2022 totalled $150.6 million, up 17% compared with $128.5 million for 2021.

On a GAAP basis, net income for the period totalled $18.3 million, or $2.69 per diluted share ($2.73 per basic share), up 74% compared with $10.5 million, or $1.51 per diluted share ($1.54 per basic share) for 2021.

On a non-GAAP basis (as described and reconciled below), net income for the period totalled $21.2 million, or $3.12 per diluted share ($3.17 per basic share), up 52% compared with $14.0 million, or $2.01 per diluted share ($2.05 per basic share) for 2021.

Fourth Quarter: Silicom’s revenues for the fourth quarter of 2022 totalled $45.2 million, up 24% compared with $36.3 million for the fourth quarter of 2021.

On a GAAP basis, net income for the quarter totalled $5.6 million, or $0.82 per diluted share ($0.84 per basic share), up 71% compared with $3.3 million, or $0.48 per diluted share ($0.49 per basic share), for the fourth quarter of 2021.

On a non-GAAP basis (as described and reconciled below), net income for the quarter totalled $6.6 million, or $0.98 per diluted share ($0.99 per basic share), up 48% compared with $4.5 million, or $0.65 per diluted share ($0.67 per basic share), for the fourth quarter of 2021.

Guidance

While we move into 2023 with an all-time-record year-start backlog, our visibility is limited due to a challenging mixed-signal environment that is impacted both by the global economic slowdown and the expected loosening of the supply chain after a long period of component shortages. We therefore project that our revenues for the first quarter of 2023 will range between $37 million and $38 million. The midpoint of this range represents 17% year-over-year revenue growth over the first quarter of 2022.

Comments of Management

Liron Eizenman, Silicom’s President and CEO, commented, “Given the year’s complex and challenging environment, we are particularly proud to report exceedingly strong results for 2022, with 17% growth in revenues, impressive operating and net margins, and 55% growth in our EPS. This confirms, yet again, the market’s clear need for our groundbreaking products, while also underscoring the benefit of our leveraged business model. The unique value proposition that we have built over the years, including high-performance products, reliable delivery, quick customization and unmatched support capabilities, continues to bring us a steady flow of new customers and orders.”

Mr. Eizenman continued, “In fact, we have entered 2023 with our highest-ever year-start backlog, driven by overwhelming demand for our new products, including especially our Edge Networking solutions. Customers ranging from telcos, services providers, OEMs and software vendors to appliance vendors, cloud players and Enterprises are coming to us for use cases ranging from SD-WAN and SASE to Enhanced-Internet and telco-dedicated routing. The Edge Networking design win we recently announced from a Fortune-500 SD-WAN vendor – a networking leader who serves customers across the Americas, APAC and EMEA - adds an important new logo to our Edge customer roster, demonstrating the quality of our pipeline of future design wins. Many of these design wins offer high potential in-and-of-themselves, and each success brings us new opportunities.”

Mr. Eizenman concluded, “Wins such as these have established Silicom as the industry’s ‘Edge Platform Provider of Choice,’ with the products, rapid customization capability, delivery capabilities and ongoing support that so many customers need. We therefore expect to continue benefiting strongly as the market transitions to the Edge Platform paradigm, driving multi-year growth for our company.”
