A copy of the press release is posted in the investor relations section of Everspin's website at www.everspin.com. Now I'd like to turn the call over to Everspin CEO, Sanjeev Aggarwal. Sanjeev, please go ahead.
Thank you, operator, and thanks everyone for joining us on the call today. Everspin delivered quarterly revenue of $15.2 million, close to the high end of guidance. We were GAAP net income positive for the sixth quarter in a row, which continues to be a strong focus of the company. A few highlights for Q3 2022. Revenue was $15.2 million, up 3% year-over-year. Product sales were $14.6 million, up 21% year-over-year. Cash flow from operations was $0.9 million. GAAP gross margin was 58.8%, and GAAP net income was $1.9 million. On October eighteenth, 2022, we reported entering into a contract to develop strategic radiation-hardened FPGA technology using Everspin MRAM IP for future Department of Defense strategic and space system requirements.
On November 2nd 2022, we announced the commercial availability of our EMxxLX STT-MRAM devices in densities from 8 Mb to 64 Mb. For our business outlook, our product backlog for balance of 2022 as of September 30, 2022, continues to be high. However, there are customer inventory adjustments that will have an impact on our backlog in the coming quarters. We continue to alleviate some of our foundry supply chain constraints, which is helping address our unfulfilled toggle demand. Recently, we announced the commercial availability of our new xSPI family of STT-MRAM devices in densities from 8 megabit to 64 Mb. It is the only commercially available persistent memory with full read and write bandwidth of 400 MB/s via 8 input-output signals with a clock frequency of 200 MHz.
The low power family of devices delivers the highest endurance, performance and data retention available today. This family of products can be an alternative solution to other memories such as SRAM, battery-backed SRAM, Ferroelectric RAM, non-volatile SRAM, and NOR flash devices. Based on the strong interest from our customers in this new xSPI family of STT-MRAM devices, we are now considering an optimized solution that is based on our 64-Mb design for lower densities from 4 Mb to 16 Mb. This will allow us to better compete with alternate memory solutions in this density range. This new family will add to our product portfolio of xSPI products down to 4 Mb. Currently, we have SPI devices available between 128 Kb and 4 Mb only.
Our leadership in STT-MRAM technology has resulted in a collaborative engagement to develop strategic radiation-hardened field programmable gate array technology using Everspin MRAM IP for future Department of Defense strategic and space system requirements. This will be a transformational FPGA device that is utilizing unique STT-MRAM IP from Everspin Technologies. In addition, we will provide design and manufacturing services as part of this project. I will now turn it over to our CFO, Anuj Aggarwal, who will take you through our third quarter financials and fourth quarter 2022 guidance. Anuj.
Thank you, Sanjeev, and good afternoon, everyone. As part of the third quarter 2022 financial results, Everspin Technologies is pleased to announce its sixth consecutive quarter of positive net income. In addition, we generated positive cash flow from operations, resulting in a healthy cash balance of $23.4 million. We delivered solid quarterly results above the midpoint of guidance, with revenue of $15.2 million, compared to $14.7 million last quarter and $14.8 million in the third quarter of 2021. We also had a positive net income of $1.9 million and positive cash flow from operations of $0.9 million for the third quarter of 2022.
MRAM product sales in the third quarter, which included both Toggle and STT-MRAM revenue, was $14.6 million versus $13.2 million in the prior quarter and $12 million in Q3 2021. Licensing, royalties, patents, and other revenue in the third quarter was $0.7 million, compared to $1.5 million in the previous quarter and $2.8 million in the third quarter of 2021. Shipments to suppliers for our largest end customer who we serve in our high-density STT product for data center applications represented 19% of revenue in the quarter versus 15% of revenue in Q2 and 23% in Q3 2021.
Turning to gross margin, GAAP gross margin for the third quarter of 2022 was 58.8% versus 58.4% in the prior quarter and 57.1% in Q3 2021. GAAP operating expenses for the third quarter of 2022 were $7.1 million versus $6.9 million in the prior quarter and $7.4 million in the third quarter of 2021. The higher operating expenses in the quarter was primarily driven by increased costs to support the new STT industrial product expected to go into low volume production in Q4. We are pleased to report third quarter positive net income of $1.9 million or $0.09 per basic share based on 20.2 million basic weighted average shares outstanding.
This compares to a GAAP net income of $1.7 million or $0.08 per basic share in the second quarter of 2022, and net income of $0.9 million or $0.05 per basic share in the third quarter of 2021. Basic EPS of $0.09 was better than the top end of our guidance range, reflecting our strategic operational discipline and strong gross margins in the face of tightening supplies and macroeconomic uncertainties. Adjusted EBITDA continues to improve period-over-period. For Q3 2022, adjusted EBITDA improved to $3.4 million compared to $3.3 million in the prior quarter and $2.5 million in Q3 2021.
Cash and cash equivalents increased to $23.4 million at the end of the third quarter, compared to $23.1 million at the end of the prior quarter and $14.6 million in Q3 2021. Cash flow from operations was $0.9 million for the current quarter, increasing year-to-date cash flow from operations to $4.3 million. Turning to our fourth quarter 2022 guidance, Everspin is confident in its growth opportunities and ability to navigate the semiconductor macroeconomic challenges. Demand for our Toggle products remains strong. Everspin expects total revenue in a range of $14.1 million-$15.1 million, with some industry supply constraints to limit supply.
Everspin expects GAAP net income per basic share to be between breakeven and $0.05, primarily influenced by expenses related to our next generation 20-nanometer STT-MRAM product development and price increases from our suppliers. I'll now turn it back over to Sanjeev for some brief additional commentary before we open it up for questions.
Thanks, Anuj. In summary, despite a challenging macroeconomic environment, we continue to build towards a profitable, sustainable growth thanks to the hard work and dedication of Everspin employees. We are excited to see the interest from our customers in our new xSPI family of STT-MRAM products and its potential impact on our revenue trajectory in the coming quarters. As planned, Darin Billerbeck, the Executive Chairman of the Board of Directors of Everspin Technologies, has transitioned back to the Chairman of the Board. Anuj and I are appreciative of the support we received from Darin as the Executive Chairman during the last year and look forward to working with him as the Chairman of the Board. Thank you everyone for joining us today. Operator, you may now open the line for questions.
At this time, we will conduct a question and answer session. To ask a question, you will need to press star one one on your telephone and wait for your name to be announced. Please stand by while we compile the Q&A roster. As a reminder, if you would like to ask a question, just press star one one on your telephone to enter the queue. We do have a question coming. Stand by. The first question comes from Nicholas Doyle at Needham. Your line is open.
Hey, this is Nick Doyle, a question for Anuj Aggarwal . Thanks for taking my questions. That first one would be just on margins. The strength continued, sequentially, last quarter year. Kind of talking about really strong yields benefiting. Is that 400 basis point or 40 basis point increase kind of the same function, or is that coming from better pricing? Any color there?
Yeah. Hi, Nick. This is Anuj. W e don't really give guidance on gross margin, but I'll say, yeah, a lot of those things have continued this quarter. We've seen great operational excellence, where we've been able to drive higher yields, and we're seeing the benefits there. We've also been able to take advantage of optimizing for a better product mix and higher loadings. I will say eventually the yields have to level off and the product mix will kind of get back to normal trends, right? That'll kind of get us back to the internal model that we've shared with everyone.
Right. Yeah, makes sense. Thanks for that color. Also last quarter, you guys were talking about the 128 product ramping volume in the second half. Could you talk about how adoption's been kind of compared to the smaller density products? I mean, you did mention that you were looking into adding to the family at the 4 MB level. Any color there?
Yeah, sure, Nick. This is Sanjeev. I think the 128 Mb product that you're referring to, that is in sampling right now. That is not the one that we have announced for commercial availability as yet. It's only from 8 Mb to 64 Mb. We are sampling the 128 megabit and, as you have said in the past, any design wins, it takes a pretty long time in the industrial sector. I think most of our design wins would probably come towards the end of 2023, and I think that's when you'll start seeing a significant or material revenue from this new product that we brought to market.
Okay. One more, if I could just squeeze in there. You talked about kind of customers, maybe pushing out orders or at least, inventory adjustments. Can you speak to kind of what end markets that you're seeing that? Is that data center and industrial? Thanks.
Yeah. First, maybe let me add some color. The Q3 for us was a record product revenue quarter, right? In terms of filling the backlog, we produced record numbers from a product standpoint. I think operations has done a great job filling some of those orders and meeting the pent-up demand. To your point there have been some cancellations and push-outs of orders and that there's been a little bit of softness, I think, in the data center space. We still have plenty of backlog that needs to get filled and we continue to see orders in 2023 as well as 2024. The backlog is still very strong.
Again, if you'd like to ask a question, please press star one one on your telephone now. One moment. No further questions remain. At this time, I'd like to turn it back over to your CFO, Anuj Aggarwal for closing remarks.
Okay. With that, we conclude today's call. Thank you all for joining us, and we look forward to reporting our progress and results on next quarter's call. Operator, you may now disconnect the call.
Thank you all for your participation in today's conference. This does conclude the program. You may now disconnect.
