Thank you, Caroline, and thank you, everyone, for joining us today. We're excited to share our fourth quarter results and significant progress we've made in 2023. We reported total revenue of $19 million in the fourth quarter, ahead of our guidance, driven by strong pull-through for an installed base of Cue readers and the continued adoption of our innovative Cue Integrated Care Platform. 2023 was a year of significant milestones for Cue. We attained two FDA authorizations, specifically a de novo approval for our at-home and point-of-care COVID-19 molecular test, the first molecular diagnostic and the first respiratory test ever to receive full FDA approval for home use, and authorization for our molecular Mpox test, our first sexual health test.
In 2023, we also submitted our RSV test and flu tests for de novo approval and were awarded a nearly $30 million contract from BARDA to develop all the way through full regulatory authorization, a combined test for flu, COVID-19, and RSV for home and professional use. In addition to our work on our flagship Cue Health Monitoring System menu, we also expanded our Cue Integrated Care Platform offerings significantly in 2023. We now offer 16 home collection test kits through our Cue Lab product line, including test kits for categories like heart health and sexual health. Through Cue Lab, we empower individuals to conveniently collect test samples at home, obtain their lab results digitally, and interact with clinicians for lab result interpretation and follow-up actions.
Rounding out our offering on the treatment side, we've extended our original electronic prescription and delivery capability for infectious diseases like COVID-19 and flu to provide treatments for many more common health needs. For example, our treatment offerings now include therapeutics for sexually transmitted infections, GLP-1s for weight management, and antivirals for cold sores. In short, we're proud of the great progress we made in 2023 in driving forth our vision of empowering people to live their healthiest lives. And we accomplished all this while streamlining our operations over the last year, reducing our cost structure by over $200 million on an annualized basis. These milestones have positioned us for an exciting 2024, and we are anticipating significant progress on our number one strategic priority, menu expansion on the Cue Health Monitoring System.
Looking ahead now, I'd like to provide some updates on test menu expansion for the Cue Health Monitoring System. First, the Cue RSV molecular test was submitted to the FDA for de novo approval last May, and we received and responded to FDA's feedback. We were asked to provide additional clinical data reflecting the addition of more infants and elderly into our clinical population. We successfully executed the clinical studies to collect the additional data, saw very good performance, and submitted the additional data to FDA. We anticipate that an approval for RSV could come in the third quarter of this year. Once we have approval, it's our intention to immediately launch the test to our customers for use with our installed base of over 250,000 Cue readers. Additionally, we believe that approvals of additional tests in our pipeline will help grow our installed reader base.
Our flu molecular test was also submitted to the FDA for de novo approval last year. During the review process, the FDA asked that we provide a greater number of clinical samples for flu B, which has had a low incidence over the last three years with almost no circulation in the northern hemisphere. We conducted additional clinical studies in the southern hemisphere and were able to collect a sufficient number of flu B samples to meet the FDA's requirement. We are still working on providing additional stability data for higher temperature storage as requested by the FDA, and thus we would expect a de novo decision for flu later this year in the third quarter. In January, we announced that the FDA had declined to issue an EUA for our flu COVID multiplex test.
You may recall that this was our first multiplex test submission and sought to enable use for both at-home and point-of-care use. This test performed very well in our clinical studies for both flu and COVID-19. However, the feedback that the FDA had was primarily for us to use a different comparator test for COVID-19 and to provide more real-time stability data. We are in active dialogue with the FDA to address these items. We hope to resubmit this application and achieve authorization in the second half of the year. To complete our respiratory pipeline update, we're making strides with our combined flu RSV and COVID all-in-one multiplex test supported by a $28 million BARDA contract.
We plan to start clinical trials this summer in the southern hemisphere and aim to have this test on market by the end of 2024 as an EUA, progressing to a full clearance in 2025. We have planned this two-stage approach to getting to market with this test, and the program is funded through the full clearance. Stage one is the EUA regulatory pathway, and in support of stage two, we will continue our clinical studies throughout the respiratory season in the northern hemisphere this winter and plan to submit for full clearance next year. Moving to our menu expansion efforts in the sexual health category, we are in late-stage development and plan to submit our herpes plus mpox multiplex test under an EUA. We've had constructive conversations with the FDA regarding our validation plan for our submission.
This test will allow us to build on our Mpox authorization last year to serve the very large, underserved point-of-care Herpes testing market. With the addition of Herpes, this test has strong potential to be a go-to test for anyone experiencing a lesion in the sexual health context. We still plan to submit for an EUA in Q2 2024 and would expect to receive authorization by year-end. Moving to our Chlamydia and gonorrhea test, this test is development complete and ready to enter into clinical studies. We have sites contracted, and the IRB process is complete. However, we strategically decided to delay the start of our clinical studies for our Chlamydia and gonorrhea test to preserve cash in the near term. This action is similar to what we decided with the Strep throat program.
We remain committed to our full pipeline of respiratory and sexual health tests while being mindful of the need to balance near-term cost and long-term opportunity and feel we have a very strong near-term pipeline in both categories. As soon as we receive FDA authorizations, we'll be ready to launch into our existing sales channels and then continue progressing menu expansion such as the chlamydia and gonorrhea and strep throat tests through clinical studies. As a reminder, all of the Cue Health Monitoring System tests share the same cartridge backbone and manufacturing process, including our combined flu COVID RSV test. Our new testing products will be made on our automated production lines without significant additional capital investment. We've demonstrated reliable production at scale, having produced and sold over 17 million molecular tests to date.
As I mentioned earlier, we've made significant progress on the Cue Integrated Care Platform, our solution that seamlessly extends the capability of our foundational Cue Health Monitoring System. In its current form, the platform enables an end-to-end customer journey from obtaining an accurate diagnosis to consultation with a healthcare provider through our apps to receiving treatment via delivery or local pharmacy pickup. We have integrated many of these building blocks over the last 18 months. In 2022, we launched Cue Care, allowing for video consultation with clinicians and prescription delivery. Since then, we've seen traction with our installed base, and today we offer tests and treatments across the care spectrum, including not just antivirals, but therapeutics ranging from GLP-1s to treatments for STIs.
In summary, 2023 was a year of significant accomplishment by the team at Cue, and we're well positioned for an exciting 2024 with a much lower cost structure as we continue to expand our test menu, drive adoption of our integrated care platform, and empower people to live their healthiest lives. We look forward to updating you on the progress in the coming quarters. With that, I'll turn the call over to Aasim.
Thank you, Ayub, and good afternoon. Now, let's walk through our fourth quarter financial results and first quarter guidance. Cue's fourth quarter total revenue was $18.8 million compared with $17.5 million in the third quarter of 2023. In the quarter, our private sector contributed 91% or $17 million of sales. Public sector revenues were $1.8 million for the fourth quarter. Total test cartridge sales were $15.5 million. Q4 product gross profit was a loss of $18.4 million. Adjusted for one-time inventory charges, product gross profit was a loss of $2.7 million. Gross profit is impacted by lower manufacturing volumes and includes non-cash items. Excluding depreciation, amortization, and stock-based compensation, our adjusted product gross profit would be positive. Total operating expenses in the quarter were $48.3 million, excluding cost of revenue and the non-cash impairment of long-lived assets.
Q4 operating expenses were down 49% from the year-ago quarter due to our cost reduction efforts. Sales and marketing expenses were $6.2 million in the fourth quarter, a decrease of 68% from Q4 2022 driven by a decrease in payroll, digital, and marketing costs. R&D expenses were $32.2 million for Q4, a decrease of 43% from $56.1 million of spend in Q4 2022. We continue to remain focused on the development of our near-term menu. G&A expenses were $9.9 million during the quarter, a decline of 48% from Q4 2022 spend of $19.2 million. In the quarter, we recognized a non-cash impairment charge of $83.6 million for some of our manufacturing lines due to low current volumes. Having said that, these lines are usable once volume picks up. As a result, GAAP net loss in the fourth quarter was $148.4 million or $0.96 per share.
Adjusted for one-time inventory and non-cash impairment charges, net loss was $49.1 million or $0.32 per share. Adjusted EBITDA was a loss of $24.4 million. Moving on to full year 2023, Cue's total revenue was $70.9 million. Private sector revenue accounted for 89% or $63 million, and public sector revenue accounted for 11% or $7.9 million. Test cartridge sales were $58.5 million in 2023. Adjusted product gross profit for 2023 was a loss of $35.2 million and excludes a disputed vendor payment and one-time inventory charges. Adjusted operating expenses for 2023 were $240.6 million, excluding cost of revenue. Sales and marketing expense was $32.6 million, R&D expense was $150.6 million, and G&A expense was $57.4 million. Adjusted operating expenses exclude the previously mentioned impairment charge of long-lived assets and restructuring expenses.
Adjusted net loss for the full year 2023 was $267.2 million or $1.75 per share, and adjusted EBITDA for the year was a loss of $163.8 million. Moving to the balance sheet, we ended the year with cash of $80.9 million. Now, I'd like to move to our guidance. We expect revenues of $9-$11 million for the first quarter. With that, I would like to thank you for your attention, and I'll now turn the call over to the operator for questions.
As a reminder, to ask a question, you will need to press star one one on your telephone and wait for your name to be announced. To withdraw your question, please press star one one again. Please stand by while we compile the Q&A roster. Our first question will come from a line of Tejas Savant with Morgan Stanley. Your line is now open. Tejas, your line is open. Our next question will come from a line of Matt Sykes with Goldman Sachs.
Hi, good afternoon. Thanks for taking my questions. Maybe just first, Ayub, for you, just on menu expansion strategy, just curious is how you're thinking about it now. I mean, I know you're submitting additional information for the flu and the RSV, but you've also got the BARDA contract for the multiplex test. Is there a rationale for continuing the work on the standalone tests and not just skipping to the multiplex given you've got the funding from BARDA? Are there commercial reasons people still want standalone tests, or are you too far along in the clinical trial portion to kind of give up on the standalone tests? I just would love to get kind of your thoughts on how you're thinking about that.
Yeah, thanks, Mike. Sorry, thanks, Matt, for the question. With RSV, we do have the de novo submitted. We already went and got the additional clinical data for infants and the elderly. We submitted it. We feel really good about the performance, and we're just awaiting it for a decision at this point. With flu, we have the de novo submitted. We went and got the additional flu B per the FDA request. Feel really good about that clinical performance, and now we're just generating some stability data at higher storage temperatures. Not only those, but we have the herpes and mpox. Herpes is super valuable. We see this as a transformative offering. There's really no additional point-of-care test. Then, as you pointed out, flu COVID RSV is a really great opportunity. Excited. It's fully funded by BARDA. It's in a really good place.
The way we look at combo tests versus single tests, they both have a place in the market. There is no approved test for RSV in the home at all, and it's a valuable test in the point-of-care as well. It's also a risk mitigation strategy. You have, of course, a lot of people will prefer the flu COVID RSV test over an RSV test, but at the same time, being able to bring that test to market soon and then follow up with something that has additional capability, that's our strategy. From a reimbursement perspective in the point-of-care, there's different billing codes, and so it could work really well to have both single target assays as well as combo tests.
Got it. Very helpful. Thank you. And then just any color you can provide on sort of the performance and/or sort of materiality of revenues in the Cue Lab business?
Yeah, from Cue Lab, Cue Pharmacy standpoint, we launched that last year, as you know. We're seeing some good trends there. We think it's a large market. So we think over time, this would be a meaningful part of our business. At this point, we're not breaking out those revenues.
Got it. Okay. Thank you very much.
Our next question will come from a line of Mark Massaro with BTIG.
Hi. Hey, guys. Can you hear me okay?
Yeah, we can hear you.
Okay, great. Cool. So could you remind me of the size of the herpes mpox market? Your decision to delay the CTNG clinical studies are a little bit surprising given that it's a well-understood market. It's a very large market. And so maybe could you just walk me through the rationale to delay the start of the CTNG clinical studies? And I understand the rationale to preserve cash, but can you just give us maybe a ballpark sense of what the clinical trial for CTNG would cost as you pursue it relative to some of the other studies like herpes and mpox?
Yeah, good question. So herpes is the most common STD. Chlamydia, gonorrhea are very common as well, but herpes is the most common. And the big difference here in terms of how we look at the sort of near-term opportunity and the cash needs is that there's an EUA pathway for the mpox-herpes combo. We already have the mpox test authorized, and we're just building on that to add the herpes detection there. So it's a very different sort of regulatory cost or clinical study-type cost comparison between herpes, mpox, and chlamydia, gonorrhea. So chlamydia, gonorrhea is a very attractive market as well, but herpes mpox has an opportunity to be a really good market but with a much different cost profile for getting it through authorization.
We see that as essentially much more near-term to revenue and with much less cash out to be able to get that validation done for authorization. That's really the key dynamic at play.
Okay. That makes sense. And then maybe a question on the update that you provided on January 4th, 2024, with respect to the FDA feedback that you received. I think you had indicated that the EUA request was not a priority, and so they decided they weren't going to advance review of the EUA COVID. Yet you are planning to pursue herpes and mpox as an EUA. Have you had conversations with the FDA about the EUA pathway? Just curious what your confidence is that that would be a priority for the agency.
Yeah, with flu COVID, we feel really good about the performance, the effectiveness, and the value of that test. In particular, we felt really good about the clinical performance. It's better than what we feel like we've seen in the market, and it's been authorized. We've been working with the FDA. There's an active dialogue to see how we can get that test through the process and address the feedback that they provided. As a reminder, we do have the flu COVID RSV test on the way. We're expecting to get that into clinical study this summer in the southern hemisphere, and that's going to have a two-stage approach. There's an EUA pathway for it for this year, but we're also following through all the way through the full submission, and that's all BARDA funded.
So with regards to the sort of wording there, they are still looking at EUAs, and it's really just about addressing the feedback more than I think it is about how they prioritize it. That's their language, but I think that at the end of the day, it's really about addressing feedback and getting the test through the regulatory process. So certainly, there are time-to-market advantages for the EUA process, and so we want to continue to leverage that where we can. But that's not in place of a de novo. It's really just a staged approach. So we wouldn't say that EUA is a sort of permanent objective. It's the sort of staged approach to getting to that full de novo. Like we did with COVID, we first got an EUA, then we got the de novo for it.
Okay, got it. And then maybe one for Aasim, just as we think about extending the cash runway. Obviously, you announced another workforce reduction in January. Just can you give us a sense for was that a $30 million use of cash in Q4? And maybe walk me through how you're thinking about cash utilization per quarter here in 2024.
Yeah, we've taken significant measures to reduce the cash utilization. In fact, despite a decline in COVID revenues across the industry in 2023, our cash utilization in 2023 was actually less than it was in 2022. So as you mentioned, we've taken $200 million out from a cost structure standpoint on an annualized basis. And look, going forward, we continue to remain very focused on our strategies highlighted in our prepared remarks, and we'll continue to remain very judicious with where we deploy our cash. So continue to remain focused on decreasing cash utilization and increasing runway.
Okay, but no targets to provide us with?
Yeah, as we think about cash and go forward, etc., as I said, we continue to decrease our cash utilization. One of the things I've mentioned in the past as well is we continue to evaluate opportunities and options to bolster our balance sheet.
Okay. Thanks, guys. Appreciate the time.
As a reminder, that is star one one to ask a question. Our next question will come from a line of Tejas Savant with Morgan Stanley.
Hello, this is Yuko on the call for Tejas. Apologize for earlier. We had some technical issues on our end. A couple of questions from me. Could you comment on your comfort with the pricing structure for both enterprise and consumer settings? And do you anticipate that current pricing for both the reader and the cartridges can still generate enough demand?
Yeah, the pricing that we've adopted, there's a lot of factors that go into that. We look at demand. We look at also reimbursement. And if you look at the reader in particular, you mentioned that. If you compare that to other laboratory analyzers in the point-of-care space, you're looking at a literal order of magnitude difference in the sort of cost to get the reader versus the laboratory analyzers that have similar capabilities. So we feel really good about the reader and the cost structure there. And there are various programs in both the consumer side and the point-of-care side that allow the customer to get the reader at no cost. And so really, our goal is to increase the install base because, as we've seen and as we mentioned for Q4, we see a lot of pull-through on each install in each reader that's in the field.
The dynamic with the reader is you want to get that out there, and then you want to allow the customer to get value from that and continue to purchase cartridges. That dynamic will be even better with more menu. That's really why menu expansion is our number one priority because we want that installed base to pull through and get value out of a lot of additional menu items.
Got it. Thank you for that color. Also, earlier in the year, you made some changes to your board of directors, and you also plan to add additional independent director to the board in the future as well. Since the changes to the board, should we anticipate any meaningful changes to your business strategy? What are some focus areas that are in discussion?
We announced a few weeks ago that we entered into the cooperation agreement with Tarsadia to add board member Rishi. This is really so we can move forward in harmony with our shareholders and really incorporate their point of view. We feel good that those conversations are now behind us and Cue can execute on our strategy. I think this shows our commitment to working with our shareholders. One of the main agenda items that we've been hearing was the cost structure needs to come down, and we had been actively working on that last year. As I mentioned in my prepared remarks, we have achieved over $200 million of cost reduction in the year. We think we're really executing on what our shareholders want to.
We're maximizing the shareholder value with our approach of lowering the cost, executing on menu expansion as our number one priority. So I think that what you've seen is that we've incorporated these strategies into our strategy as well.
Thank you.
Thank you. This concludes today's conference call. Thank you for participating. You may now disconnect.
