Ladies and gentlemen, thank you for standing by. Welcome to the Silicom Q1 2022 results conference call. All participants are at present in listen-only mode. Following management's formal presentation, instructions will be given for the question and answer session. As a reminder, this conference is being recorded. You should have all received by now the company's press release. If you have not received it, please contact Silicom's investor relations team at GK Investor & Public Relations at 1-212-378-8040, or view it in the news section of the company's website, www.silicom-usa.com. I would now like to hand over the call to Mr. Ehud Helft of GK Investor & Public Relations. Mr. Helft, would you like to begin, please?
Yeah, thank you, operator. I would like to welcome all of you to Silicom's Q1 2022 results conference call. Before we start, I'd like to draw your attention to the following safe harbor statement. This conference call contains projections or other forward-looking statements regarding future events or the future performance of the company. These statements are only predictions and may change as time passes. Silicom does not assume any obligation to update that information. Actual events or results may differ materially from those projected, including as a result of our increasing dependency for substantial revenue growth on a limited number of customers in the evolving cloud-based SD-WAN, NFV, and Edge markets.
The speed and the extent to which solutions are adopted by these markets, the likelihood that we will rely increasingly on customers which provide solutions in these evolving markets, resulting in increasing dependence on a small number of larger customers, difficulty in commercializing and marketing Silicom's products and services, maintaining and protecting brand recognition, protection of intellectual property, competition, disruption to our manufacturing and development, along with general disruption to the entire world economy relating to the spread of the novel coronavirus, and other factors identified in the document filed by the company with the SEC. In addition, following the company's disclosure of non-GAAP financial measures in today's earnings release, such non-GAAP financial measures will be discussed during this call. Such non-GAAP measures are used by management to make strategic decisions, focus future results, and evaluate the company's current performance.
Management believes that the presentation of these non-GAAP financial measures is useful to investor understanding and assessment of the company's ongoing core operation and prospect for the future. Unless otherwise stated, it should be assumed that financials discussed in this conference call will be on a non-GAAP basis. Non-GAAP financial measures discussed by management are provided as additional information to investors in order to provide them with an alternative method for assessing our financial conditions and operating results. These measures are not in accordance with GAAP or a substitute for GAAP. A full reconciliation of non-GAAP to GAAP financial measures is included in today's earnings release, which you can find on Silicom's website. With this now, let me introduce the people we have on the line today, Mr. Yeshayahu Orbach, the CEO, Mr. Liron Eizenman, COO, and Mr. Eran Gilad, CFO.
Yeshayahu Orbach will begin with an overview of the results, followed by Eran Gilad, who will provide the analysis of the financials. We will then turn over the call to the questions and answer session. With that, I would now like to hand over the call to Yeshayahu Orbach. Yeshayahu Orbach, please.
Thank you, Ehud. I would like to welcome all of you to our financial results conference call discussing our Q1 2022 results. I would first like to welcome Liron Eizenman to our call for the first time. As of July 1, he will transition to the position of President and CEO, replacing me, and I will become Executive Vice Chairman of the board. Over the past six years, as part of a carefully structured long-term transition plan, I have worked closely with Liron, and I have every confidence in his ability to capitalize on our strong market position and bring Silicom to the next level in its long-term development. Liron has served in key executive roles within our company, currently as COO and CEO of our North American subsidiary, Silicom Inc.
Liron was the visionary behind Silicom's Edge networking solutions strategy and was instrumental in driving the company to its leadership position in the SD-WAN/Edge platforms market. While I will continue to work very closely with Liron as part of my new role, I wish him much luck in the new position. Now to the results of the quarter. We are pleased with our start to 2022, with strong Q1 results demonstrating 11% revenue growth year-over-year to $32 million. This is at the center of our expected target range of between $31 million and $33 million. We reported our 69th quarter of continued profitability with net income of $3 million and earnings per share at $0.44.
We are all the more pleased to continue demonstrating growth despite a continued background of significant component shortages and tight supply chains, which are significant headwinds, and the impact is being strongly felt across our entire industry. It is clear that given the continued high market demand, which is well in excess of supply, analysts do not expect the shortage to abate during the current year. We continue to place significant effort into maximizing what we're able to manufacture and deliver, meeting as much of the high demand for our product as possible, and I will further address the efforts were taken later on in the call. Indeed, the exceptionally strong market demand for our product range. This includes our Server Adapters, SD-WAN/Edge platforms, as well as 5G/O-RAN products.
This has now led to the highest ever backlog in Silicom's history, and this underlies my optimism that we have a significant runway of expected growth ahead of us. Given such high market demand and record backlog levels on one hand, and the component shortages on the other to support expected product sales, we took the strategic decision to significantly increase our inventory levels. As you may notice, our inventory today stands at about $95 million, which is an increase of almost $20 million in one quarter. Using our strong cash position to build our inventory levels to support the current demand, while protecting us from shortages and non-commits by chip vendors, will continue to remain a strategic priority for us. Our ability to do this is a significant competitive advantage for us.
It allows us to serve our existing customer base, delivering products which are not easily available today, while attracting new customers and new business. I believe that in today's market, this strategy will provide the highest long-term return on our existing cash position. We continue to capitalize on the trends of disaggregation and decoupling, which are among the most significant transitions of IT architecture in recent history. The markets to which these trends play into are the fast-growing SD-WAN market and the developing 5G ORAN market. These are both key strategic markets in which we continue to demonstrate and build on our very strong capabilities and positioning. The SD-WAN market today contributes tens of millions of dollars to our revenues and is in a growth phase, while the 5G ORAN market is still in the early introduction phase.
Our ongoing success in SD-WAN makes us optimistic about our potential in the 5G O-RAN market, which have been endorsing the disaggregated and decoupling approach. Our existing wins, our highest ever backlog, combined with the potential opportunities in our pipeline, underlie our optimism that our achievements so far are just the tip of the iceberg. I would like to discuss some of the new recent wins we announced. In February, we added a new tier one European telco customer to our growing list of top-tier telco clients. This new customer selected a customized version of our Edge Networking Platform and placed a $1 million purchase order, forecasting a ramp up to an annual approximate run rate of $5 million per year. We won this design win through our partnership with a leading provider of SD-WAN software.
We chose our hardware as the highest performance complement to its next generation offerings. This follows our May 2021 design win with the global telco giant Telefónica and a few other design win with US tier one telcos and service providers. The win confirms our strong positioning in the SD-WAN ecosystem and demonstrates the competitive advantages of our Edge Networking Solutions. Strategically, it emphasizes the value of our strong cooperation and partnerships with many SD-WAN software vendors in the current era of hardware and software decoupling. Last month, we announced a major Edge networking design win from an existing customer, a leading US communication service provider, for customized High Runner Edge networking products. We delivered $3 million in equipment for the project's first phase and received second phase purchase orders totaling a further $3 million to be delivered this year.
The customer forecasts that the total value of the design win will reach approximately $15 million. This is another demonstration of the proven ability of our Edge products to increase network throughput and decrease latency, which are key differentiating advantages for us. I'd like to provide more color on how we've been addressing the component shortage. We have already been living under the issue for a year, and our achievements of continued revenue growth, stable growth margins, and continued profit growth under these conditions demonstrate that we are overcoming many of the problems successfully, which is why we remain optimistic. The steps we've taken and continue to take are as follows. One, as you've seen, we have leveraged our strong balance sheet to build up our inventory of raw materials.
These are backed by customers' existing POs and commitments, buying available stock of components, both from the vendors and in the free market, and expediting delivery if need be. We are working with customers to optimize product availability and providing them with alternative solutions. For example, replacing products of which the delivery is challenging with other products with better availability. Finally, we've been redesigning our products to use more available components to achieve optimized availability. Obviously, when designing new products, our current initial criteria is optimizing for component availability.
Moving forward. While we predict that the shortages will persist for the coming year, despite it, given that our experience and success in dealing with the issue, combined with a very strong market demand for our connectivity solutions and our broad range and increasingly large design wins, all support our expectations for continued solid double-digit growth rates for 2022 and beyond. Which brings me to our guidance for the Q2 of 2022. For the Q2 of 2022, we expect revenues at between $33 million and $35 million, which at the midpoint represents growth of approximately 12% over that of the Q2 of 2021. I would like to note that these growth rates represent our estimates as to the level of our success in indeed mitigating the component situation. Had there been no such situation, our forecast would have been much higher.
In summary, we remain very pleased with our performance to date, and 2022 has started well. This is despite the supply chain difficulties and shortages. Even despite the shortages, we continue to stand by our expectations that given the current strong demand in the market, we expect to see double-digit compounded revenue growth for the coming few years, which will accelerate once the global supply chain issues are finally resolved. Our expectations are built on the base of our recent major design wins. The scales of each is well ahead of what we have traditionally experienced. Furthermore, our backlog is at the highest level it has historically been for Silicom, and all this provides us with strong revenue visibility over many quarters and years.
More broadly, our focus on some of the fastest-growing markets in the networking space, which are developing out of the trends which we have correctly predicted and positioned ourselves for, as well as our current long and deep pipeline, makes us further optimistic. With that, I will now hand over the call to Eran for a detailed review of the quarter's results. Eran, please go ahead.
Thank you, Shaike, and hello, everyone. Revenues for the Q1 of 2022 were $32.1 million, compared with revenues of $29 million as reported in the Q1 of last year. Our geographical revenue breakdown over the last twelve months were as follows, North America, 69%, Europe and Israel, 25%, Far East and rest of the world, 6%. During the last twelve months, our top three customers together accounted for about 30% of our revenues. I will be presenting the rest of the financial results on a non-GAAP basis, which excludes the non-cash compensation expenses in respect of options and RSUs granted to directors, officers and employees, acquisition-related adjustments, as well as lease liabilities financial income. For the full reconciliation from GAAP to non-GAAP numbers, please refer to the press release we issued earlier today.
Gross profit for the Q1 of 2022 was $11.1 million, representing a gross margin of 34.5% in the upper half of the range of our gross margin guidance of 32%-36%, and compared to a gross profit of $10.1 million, or gross margin of 34.7% in the Q1 of 2021. The variance in the gross margin is a function of the specific product mix sold in the quarter. Operating expenses in the Q1 of 2022 were $7.7 million, compared to $7.1 million reported in the Q1 of 2021. Operating income for the Q1 of 2022 was $3.4 million, an increase of 12% compared to operating income of $3 million as reported in the Q1 of 2021.
Net income for the Q1 was $3 million, at a similar level compared to $3 million in the Q1 of 2021. Earnings per diluted share in the quarter were $0.44, compared with EPS of $0.42 as reported in the Q1 of last year. Now, turning to the balance sheet. As of March 31, 2022, the company's cash equivalents and marketable securities totaled $43.1 million with no debt and $6.47 per outstanding share. During the quarter, we further executed on our third $15 million share buyback plan, which we started on May 4, 2021. During the Q1 , we purchased approximately 78,000 shares at a total cost of $3.3 million.
In summary, I would like to hand back over to the operator for question and answer session. Operator?
Thank you. Ladies and gentlemen, at this time we'll begin the question and answer session. If you have a question, please press star one. If you wish to cancel your request, please press star two. If you are using speaker equipment, kindly lift the handset before pressing the numbers. Your questions will be pulled in the order they are received. Please stand by while we pull for your questions. I repeat, if you have a question, please press star one. The first question is from Matt Desert of Needham & Company. Please go ahead.
Hey, guys. Matt on for Alex here. Thanks for taking our questions. Wondering if you could start off by talking about the latest on supply with growing macro concerns in China and other systems companies seeing worsening conditions for component availability. What are you guys seeing out there? If you could touch on that, please.
Well, obviously, we do not see any improvement for now in the component situation, which was very bad and is very bad. We may experience some more difficulties here and there, but overall the situation is really bad. However, as I've mentioned before, we have taken steps ahead of time, mostly in terms of creating inventory, which would help us with the deliveries with customers. Again, we would have challenges. It's not gonna be simple and, well, not only it's not gonna be simple, I'm pretty sure that we would not be able to deliver to our customers everything that they're after. However, I think that looking at overall industry situation, then we are relatively in a good place. Still challenging, but relatively in a good place.
That's great. Bringing it back to the inventory. Yeah, you talked about that large $20 million sequential increase. Can you just touch on your ability to continue to build that out and the opportunity and growth that presents for you guys?
Well, first of all, I would say that indeed this is our strategy, and we are planning to continue with that strategy as much as possible. Obviously, once we're doing that, we're careful looking at every other parameter within the company to be able to do that, but we are taking advantage of our strong positioning, I would say. The strategy remains like that, which means we would continue to take on the inventory, which by the way is committed, as I mentioned. I mean, we have the largest ever backlog position ever in the history of the company, so which helps us in moving forward with that strategy, and we plan to continue with that while being careful, making sure that all other company parameters are maintained at the required level.
Great. Has there been any slippage or disruption at all to the timeline and ramping of these contract wins that you guys have?
Disruptions to what? I didn't hear the last few words of your question.
To the contract and design wins that you guys have been growing.
Oh, no. I mean.
Has there been any?
We don't feel any disruptions at all to the contracts and to the design wins. The only disruptions and challenges that we're feeling is these days in the supply chain, which obviously creates challenges in deliveries. From a business perspective, getting new design wins, getting new POs, et cetera, we don't feel any disruptions at all.
Can you talk about the propensity to buy, particularly in EMEA and APAC, given the macro concerns that are going on over there? Have you seen any delta in demand from those theaters?
Well, first of all, as you could note, most, I believe approximately 70% of what we're selling is to the United States. Obviously there was no impact there. EMEA represents 20-something%. A significant part of that is in Israel. I wouldn't say that there was no impact at all, but it is not something which is impacting our business.
Great. Lastly, on the CEO transition. Seems like Liron's been instrumental to the SD-WAN strategy. Can you talk about the plans for that transition and any thoughts or changes from the strategy in that perspective going forward?
Well, I believe that, at least, I mean, talking to Liron, I believe that you are not going to see any change in strategy. It seems to me that Liron believes in the same strategy that I believe, that the board of director believed in. I don't see any change in strategy in that respect. I think that Liron would do a really excellent job, and I think that the timing is even perfect because with this huge backlog that we're having and a lot of things to execute, I think that these are areas that he could be much better than me, so it's better. Overall, I would say that this is a long process.
This has been a long process, six years process that we structured very carefully for him to learn every part of the company. His impact on the strategy is already within our current strategy. I would say more of the same strategically, probably better results.
That's great. I guess one more, if I may. Could you just touch on, obviously the shekel is, has been plummeting recently. Could you just refresh us on your strategy for hedging and talk about how that's impacting you throughout the duration of the year?
Yes, sure. First of all, I remind everybody that we do not hedge anything. In quarter one, indeed, we had a positive effect of exchange rate differences. Not significant amounts, but still, a minor positive effect compared to negative and sometimes quite significantly negative effect in previous quarters.
Great. I'll yield the floor. Thanks for taking my questions, guys.
If there are any additional questions, please press star one. If you wish to cancel your request, please press star two. Please stand by while we pull for more questions. There are no further questions at this time. Before I ask Mr. Orbach to go ahead with his closing statement, I would like to remind participants that a replay of this call will be available by tomorrow on Silicom's website, www.silicom-usa.com. Mr. Orbach, would you like to make your concluding statement?
Yes. Thank you, operator. Thank you everybody for joining the call. We wish you all health, and we look forward to hosting you on our next call in three months. Good day.
Thank you. This concludes Silicom's Q1 2022 results conference call. Thank you for your participation. You may go ahead and disconnect.
