Prepared Remarks:

Operator

Good afternoon. My name is Rob and I will be your conference operator today. At this time, I would like to welcome everyone to the Maravai LifeSciences first-quarter 2023 earnings conference call. All lines have been placed on mute to prevent any background noise.

After the speakers' remarks, there will be a question-and-answer session. [Operator instructions] Thank you. Deb Hart, head of investor relations, you may begin your conference.

Deb Hart -- Head of Investor Relations

Thank you, Rob, and good afternoon, everyone. Thanks for joining us on our first-quarter 2023 earnings call. Our press release and the slides that accompanied today's call are posted on our website and are available at investors.maravai.com. As you can see on our agenda for today on Slide 2, Carl will first provide you with a business update and Kevin will review our financial results and guidance.

Trey Martin, president of our biologic safety testing; Drew Burch, executive vice president, nucleic acid products; and Becky Buzzeo, our chief commercial officer, will join the call for the question-and-answer session following the prepared remarks. We remind you, management will make forward-looking statements and refer to GAAP and non-GAAP financial measures during today's call. It's possible that actual results could differ from management's expectations. We refer you to Slide 3 for more detail on forward-looking statements and our use of non-GAAP financial measures.

Our just-issued press release provides reconciliations to the most directly comparable GAAP measures. Please also refer to Maravai's SEC filings for additional information on the risks and uncertainties that may impact our operating results, performance, and financial condition. Now I'll turn the call over to Carl.

Carl Hull -- Chief Executive Officere

Well, thank you, Deb, and good afternoon, everyone. We appreciate having you join us for a call today. Let me give a quick recap of the quarter that highlights our innovative new products that we are introducing and provide a few business updates before turning the call over to Kevin. Let's start with our first-quarter results on Slide 5.

Today, we reported $79 million in revenue for the quarter, $24 million in total adjusted EBITDA, and $0.03 in adjusted fully diluted EPS for the quarter. Revenue results were within the range of expectations for the first quarter that we shared with you during our fourth-quarter conference call. While our performance in the quarter was consistent with our expectations, like other players in the field, we do note that broader market factors will likely continue to impact the business into the second quarter. Kevin will go into more detail on the results and our revised guidance later in the call.

Our nucleic acid production business had revenue of $61 million in the first quarter. This includes an estimated $45 million of base nucleic acid production revenue. The biologic safety testing revenue was $18 million in the first quarter. On Slide 6, you'll see that our adjusted free cash flow in the quarter was $23 million.

Cash on hand at the end of the quarter was $628 million, down only 4 million from the year-end despite our having paid $70 million upfront in the quarter for the Alphazyme acquisition. Debt sits at $537 million, gross, thus we maintain a $91 million net cash position. This puts us in a great position to fund our long-term strategy of growth through organic investments in our own capabilities while we simultaneously pursue external M&A. We continue to see multiple strategic opportunities in our space where we will endeavor to responsibly deploy some of this cash.

As we close out the first quarter of the year, we remain focused on, first, expanding our product portfolio; second, advancing our market leadership in the mRNA space; and finally, accelerating the introduction of scientific innovations in ways that support our customers rapidly evolving needs while continuing to invest in operations, manufacturing, and people to support our base business growth. To the first point on product portfolio expansion and our focus on innovation, let's now turn to Slide 7. As many of you know, CleanCap is not a single product, but rather a portfolio of capping analogs. We have several versions of CleanCap that we have developed for both messenger RNA synthesis and for self-amplifying messenger RNA.

Yesterday, at the TIDES USA scientific meeting held here in San Diego, our chief innovation officer, Dr. Kate Broderick, introduced the newest addition to the CleanCap product portfolio, CleanCap M6, which we are extremely excited about. CleanCap M6 is our most robust catalog to date and represents a significant advancement in the field of messenger RNA capping. We believe this innovative capping analog to be the most efficient capping strategy now available in the market, and we believe that it will represent the next generation of novel mRNA caps.

Of particular note is the fact that it produces the highest in vivo protein expression we have seen for any CleanCap analogs so far. In our comparison studies, CleanCap M6 consistently produced 30%-plus higher protein expression than comparable enzymatic capping methods. Higher expression can result in greater potency or more effective dosing of messenger RNA drugs. Similar to our other CleanCap products, CleanCap M6 generates a naturally occurring cap one structure via co-transcriptional capping.

This provides our customers with the benefit of a simplified and higher-yield messenger RNA manufacturing process with a shorter manufacturing time, which leads to better economics in mRNA production. Slide 8 provides a quick recap of the favorable attributes of CleanCap M6. We know that CleanCap already is the most economically favorable capping process on the market. We recently commissioned a strategic consulting firm to study the manufacturing costs associated with the three methods of mRNA capping: enzymatic; ARCA, which stands for anti-reverse cap analog; and CleanCap.

The study considered the complete economic picture around mRNA capping, including actual customer experiences, costs, and future needs. Due to messenger RNA's inherent instability, in vitro synthesis of mRNA can be a challenging biochemical reaction and the need for high purity necessitates stringent purification and QC testing. As we saw in the recent study, depending on the technology, equipment, downstream purification processes, and user expertise, the expected overall yield of cap mRNA can vary greatly, ranging from 50% with enzymatic capping to 95% associated with the use of CleanCap technology. And I'm just back from visiting one of our customers who has been conducting pre-market evaluations of M6 and some of our even newer capping analogs.

And they're very excited about the performance improvements being seen in their own hands. In fact, we've already begun to take initial orders for this new product. Slide 9 shows the direct reagent costs for the GMP manufacturing of one gram of messenger RNA using each of the three outlined mRNA capping methods. This figure demonstrates how enzymatic capping and ARCA require additional reagent costs for the same amount of product due to their reduced yields per reaction.

It is estimated that both enzymatic capping and ARCA technologies lead to higher total reagent cost per quantity of produced mRNA, an estimate of $248,000 for enzymatic, $221,000 for ARCA, and $215,000 for CleanCap technology. This data demonstrates how influential the recovery rate or yield is on the total reaction reagent costs. Beyond this, there are additional advantages to CleanCap, including the reduced purification cost, time savings, and producing products with a simpler manufacturing process, and labor savings. Slide 10 compares the total manufacturing cost of CleanCap versus ARCA and enzymatic capping.

As you can see, CleanCap is 30% less than enzymatic capping and 20% less than ARCA. As a result of this third-party analysis, we have developed robust selling tools for our business development and commercial teams to use to help drive share gain for the CleanCap portfolio, especially versus enzymatic capping methods. The CleanCap M6 analog adds to these economic benefits with the additional advancement of higher protein expression from the equivalent amount of mRNA. Together, we think that this is a game-changing analog for manufacturing more potent messenger RNA therapeutics and vaccines.

Sticking with this new product innovation theme, let's turn to Slide 11. Also, with the TIDES scientific meeting this week, Glen Research, our high-quality provider of fluorophores and quencher labels and modifiers for oligonucleotide synthesis, published Glen Report 35.1. The Glen Report has been in consistent or constant publication since 1987 and serves as a well-regarded resource for the many scientists engaged in DNA and RNA research and oligonucleotide synthesis. Four new products were announced in our latest issue.

As Glen continues to expand the breadth of its oligonucleotide synthesis products, one I'd like to highlight today is the expansion of our proprietary serinol product line with the launch of 3'-azido-modifier serinol CPG, or controlled pore glass, reports. Click chemistry is a really popular method of conjugation and bioconjugation, and its discoverers were awarded the 2022 Nobel Prize in chemistry. Most people will use one molecule labeled with an alkyne group and another labeled with an azide group. When mixed, the linkage formed between the two entities can feel as simple and easy as a click.

Glen Research has now expanded our set of products to facilitate the use of oligonucleotides in click chemistry. The 3'-azido-modifier serinol CPG is convenient to use for this application and produces excellent results. Due to its advantages over other approaches, it is possible that this new support may become the most popular method for preparing azide-labeled oligonucleotides. As you can see, we believe that investing in new product innovation is a key driver for creating value in this part of our business as well.

We are in an exceptional position to win customers early for both product and technology adoption. Turning to our commercial strategy. By winning early in the discovery process, especially with our CleanCap technology, we are able to cross-sell NTPs and other raw materials at earlier stages of the clinical pipeline. And that is exactly what our commercial team for NAP is tasked to do, win first with CleanCap at the earliest stages of the clinical pipeline, cross-sell NTPs and other raw materials, and then grow with our customers to support them with their later-stage developments.

This can include supporting them with both RUO and GMP materials depending on their needs and when they choose to move to higher-grade inputs. Let's turn now to Slide 12 and let me share some data with you on our progress with customer adoption. One year ago, in the first quarter of '22, we had 185 CleanCap reagent customers on a rolling 18-month basis. As we closed Q1 of this year, that number is now 312 customers, up 69%.

These are customers that order CleanCap as a stand-alone reagent product. We ship it to them or their preferred contract manufacturer and they then use our capping analogs in their own messenger RNA manufacturing processes. This could be for research and discovery activities, preclinical development, and with our GMP offering, clinical manufacturing of messenger RNA. We also track our CleanCap mRNA discovery customers.

These are customers at the very early stages of their programs who look to try to manufacture messenger RNA on their behalf using CleanCap as their capping method. Their activities are mostly for early research and discovery, including assay development, target identification, and in vitro cell models. This group of customers has grown from 585 last year to over 600 customers today, up roughly 3%. As these early customers continue through their discovery work, we expect many will mature into mRNA GMP services where they would take several of their top candidates and upgrade them to our GMP manufacturing process, which includes process development to a larger-scale, phase-appropriate methods validation, and collecting documentation that would support an IND filing.

Our GMP mRNA customers have grown from 55 to 61 over the last year, up 11%. And lastly, the number of our GMP mRNA customers who have advanced to the clinic is now 26 programs. So, let me now share a couple of examples of what this customer journey means over time to Maravai from a revenue standpoint. Slide 13 shows an example of a customer we started working with a few years ago in their early discovery phase.

They now have several programs underway for precision genetic medicine. In 2018, they were less than $1 million revenue contributor. By 2022, they were ready to move to phase 1 trial and ordered nearly $8 million products from us. This particular customer uses a CleanCap and our N-1 methylpseudouridine-triphosphate.

This customer is also currently evaluating using Alphazyme enzymes. Slide 14 is an example of a different customer that we have worked with on nucleic acid services. Their target is a personalized cancer vaccine. This customer represented $102,000 in revenue in 2018 and, in 2022, was over a $3 million customer.

This customer uses our GMP CleanCap mRNA manufacturing and began their product development journey with us during initial R&D construct screening. We worked closely with them to facilitate their construct selection and manufacturing of their various GMP batches. As these customers progress through our GMP services with their preclinical and early clinical phase work, we also want to support them through later-stage development, which is why we invested in our new Flanders facility. So, you can see we have a unique opportunity to drive CleanCap inclusion across our growing mRNA customer base while providing other critical GMP raw materials to improve in vitro transcription reactions and grow with our customers as they advance their own programs.

Now turning to Slide 15 and our biologics safety testing business. Our products and services in this business support the cell and gene therapy, vaccine, and biologics drug manufacturing markets by providing process-related and purity analytics along with offering innovative viral clearance prediction solutions that help our customers ensure the safety of their biopharmaceutical products. We continue to innovate here to bring improved products to market to support our customers. Late last year, we announced the launch of the MockV RVLP Kit.

This kit enables bioprocess scientists to quantify the removal of retrovirus-like particles, or RVLPs, produced endogenously by Chinese hamster ovary, or CHO cells, during biopharmaceutical manufacturing. Today, we are happy to report strong market uptake of this kit and technology by several major biopharma companies and CDMOs. In addition, we are closely monitoring a recently published draft revision of the ICH, which is the International Conference on Harmonisation, guideline on viral safety evaluation of biotechnology products derived from cell lines of human or animal origin. This considers the use of CHO-derived endogenous viral particles, or RVLP, for viral clearance experiments.

If recommended in the final published guideline, this could be a very positive tailwind for the entire BST business. In March, our BST team launched the PG13 HCP ELISA Kit. Bioanalytic customers can use this kit during purification and process development, as well as in quality control and product release testing. The PG13 kit represents the 24th expansion platform -- excuse me, expression platform we provide analytics for and solidifies our commitment to supporting cell gene therapy.

As in NAP, we continue to innovate and scale our offerings in BST to ensure superior technical support, the highest-quality services and offerings, and the most comprehensive catalog of products to meet our customers' needs. Now moving on to Slide 16 and some organizational updates. First, we're happy to welcome Drew Burch to our leadership team. Drew joined us in April as executive vice president of nucleic acid products.

For those of you not familiar with Drew, he has over 30 years of strategic, operational, commercial, and financial experiences in the life sciences industry. I look forward to him playing an incredibly important role on our team as Maravai continues to scale and differentiate itself as a trusted supplier of nucleic acid and chemistry products for the life sciences industry. I'm confident he will build on the momentum of the NAP operating division and help us continue to provide best-in-class products that support the important work of our customers. Second, the integration of the Alphazyme acquisition is going very well.

We are actively qualifying their enzymes into our nucleic acid services workflow and building their commercial team. We've also decided to add to the Alphazyme facility footprint with the addition of an adjacent 4,000 square feet to provide an expanded R&D space. Alphazyme extends our capabilities in the manufacturing critical enzymes that support flexible, scalable production within a universally acceptable infrastructure, and we remain incredibly enthusiastic about our combined opportunities. We also remain active in pursuing other inorganic growth opportunities and look forward to being able to announce additional acquisitions in 2023.

We are committed to expanding our reach as a key specialized raw materials supplier. And we are actively working to increase our international footprint so that we may improve our ability to directly serve our global customer base. So, before I turn the call over to Kevin, I'd like to let you know that in late March, we published our second environmental, social, and governance report. This report covers the 2022 fiscal year and provides an expansive look into our rapidly evolving ESG program with tangible examples of how we are making a positive impact on stakeholders and positioning our business for sustainable growth.

I highlighted some key aspects of our progress during our fourth-quarter call, but I encourage you to review the report on the Investors section of our website. The comprehensive 41-page report is the culmination of our enterprisewide effort to deliver holistic value to our stakeholders while scaling operations and managing rapid growth in a socially and environmentally responsible manner. On Slide 17, you'll find some of the highlights from the report. We are very proud of the team's work to date and are committed to being a strong corporate citizen.

We look forward to keeping you apprised on our journey. I'll now ask Kevin to cover more details on our first-quarter performance and provide an update on our multiple facilities expansion projects. Kevin?

Kevin Herde -- Executive Vice President, Chief Financial Officer

Thank you, Carl. Good afternoon, everyone. I'm happy to review our financial results for the first quarter and to provide an update on the multiple facilities expansions we have underway. Starting on Slide 19.

As you've seen in our press release this afternoon, our Q1 2023 revenues were $79 million. As we stated in our Q4 2022 earnings call, we anticipated Q1 2023 revenues to be in the range of between 75 million to 80 million, and thus, our performance for the quarter was in the high end of our anticipated range and was consistent with our expectations. We present basic EPS, fully diluted EPS, and adjusted fully diluted EPS. Basic EPS is net income attributable to our class A shares divided by the weighted average Class A shares.

Our fully diluted EPS equals net income prior to noncontrolling interests, divided by the weighted average for both Class A and Class B, and other dilutive securities to the extent they are dilutive. And adjusted fully diluted EPS equals adjusted non -- net income, divided by the weighted average of both Class A and Class B shares and other dilutive securities. Both our basic and fully diluted EPS for the quarter were $0.00, while adjusted diluted EPS was $0.03 per share. This was also in line with our internal expectations for the quarter.

Our GAAP-based net loss before the amount attributable to noncontrolling interests was 1.3 million for the first quarter of 2023, reflecting the lower revenues and the impact of acquisition-related costs. Our adjusted EBITDA, a non-GAAP measure, was 24 million for Q1, resulting in an EBITDA margin of 30% in Q1 2023. Certainly, our EBITDA margin was lower than we have seen in a while as a result of the lower revenue base. However, even with our revenue base being the lowest we've seen in almost three years, our margin is still very strong when compared to most companies in our space, including much larger, more mature companies.

In fact, when we look at the selection of six companies that have reported here already in Q1 2023 and had adjusted EBITDA, including, in alphabetical order, Avantor, BioTechniques, Danaher, Repligen, Sartorius, and Thermo Fisher, our EBITDA margin of 30% compares well to the average of that group of six companies of 2 %, This is true even in a low revenue quarter and with substantial ongoing investments in our overall infrastructure to support our future growth. We continue to invest and stay laser-focused on our long-term strategic objectives which require the continued investment in our overall capabilities. Let's move to Slide 20. As Carl mentioned, we continue to have a strong balance sheet and cash flows.

Our cash and cash equivalents, which are GAAP metrics, totaled 628 million at March 31st, 2023, and we generated $85 million in cash flow from operations in the first quarter, mostly based on the AR collections from a strong Q4 2022. This strong operating cash flow allowed us to fund both the Alphazyme acquisition in the quarter as well as our capital expenditures in the quarter. Our adjusted free cash flow for the quarter was $23 million. Adjusted free cash flow, a non-GAAP measure, we define as adjusted EBITDA less capital expenditures.

We ended Q1 with 537 million in long-term debt and 628 million in cash. This cash and debt structure allows us maximum flexibility as we continue to actively evaluate additional M&A opportunities. As we look at our Treasury operations, we've been tightly managing our cash. With the interest cap contract we have in place, our gross interest expense is effectively capped at 6.5%.

And with our excess cash sweep activities and nice yields on liquid overnight investments, our overall net interest expense sits below 4%. Now turning to Slide 21. I'll provide some more insights into our business segment financial performance for the quarter. As Carl mentioned earlier, our nucleic acid production business represents $61 million in revenues for the first quarter.

Nucleic acid production represented 78% of the company's total revenue in the quarter and generated 28 million in adjusted EBITDA in the quarter for a segment margin of 45%. CleanCap revenues from our COVID-19 vaccine customers were approximately 16 million in the first quarter of 2023, in line with our expectations for the quarter. Now we see this going down to about 10 million here in the second quarter of 2023 and maintain our guidance of 100 million in total contributions to our 2023 revenues. We did see additional orders for COVID-related CleanCap demand and have brought the total percentage of our full-year total shipped or committed up to about 65% of our full-year estimate.

Our biologic safety testing business contributed 22% of the company's revenue in the first quarter. Our biologic safety testing business delivered nearly 18 million in revenues in the quarter and 14 million of adjusted EBITDA in the quarter, a margin of 78%. Our biologic safety testing business hit the highest revenue levels since Q1 2022 and was up 14% from the last quarter of Q4 of 2022. We believe we are seeing the leveling out of the impact of China shutdowns, and we believe we will see a return to normal business in the China region in the mid to late second quarter here of 2023.

Corporate expenses that are not included in the segment-adjusted EBITDA totals above were 18 million in the quarter, increasing from both the prior year first quarter and slightly from our most recently completed fourth quarter of 2022. These expense increases are associated with the continued build-out of our shared services functions. Now moving to Slide 22 and an update on our facility expansion project. We have completed building construction of Flanders 1 and taken occupancy, and we expect the same for Flanders 2 in the second quarter.

We also began working out of our new building for our biologic safety testing business. Our teams remain extremely enthusiastic about the unique capabilities we can offer our customers from our expanding facility footprint. Turning to slide 23 and our guidance. Our first-quarter results came in as anticipated, yet we acknowledge that the broader biotech market is sluggish and will likely impact our original growth projections for the year.

Thus, we are updating our 2023 full-year revenue guidance down $20 million at the midpoint to a range of $400 million to $440 million. This puts our base business revenues in the range of $300 million to $340 million. With regards to gating of overall revenues, we see Q2 had a total of around $70 million or so, which includes the previously mentioned approximately $10 million contribution from COVID CleanCap demand. We then anticipate more normal growth in the second half of the year with the remaining COVID CleanCap contribution most likely occurring in Q4.

We estimate our adjusted fully diluted EPS in the range of $0.27 to $0.33 and adjusted EBITDA of between 155 million and 175 million. Our guidance is also based on the following expectations as listed out on Slide 24. Interest expense, net of interest income, between 18 million and 22 million; depreciation and amortization between 38 million and 42 million; stock-based compensation, which we show as a reconciling item from GAAP to non-GAAP EBITDA, to be 34 million to 38 million. This also includes an as-if fully converted share count of 252 million shares and an adjusted effective tax rate of 24%.

Thank you for your time today and for your support of Maravai. Now I'll turn the call back to Carl for some final remarks.

Carl Hull -- Chief Executive Officere

Thanks, Kevin. So, to wrap up on Slide 26. We are playing in the right target markets with strong leadership positions and exceptional opportunities for base business growth, as we continue to innovate in messenger RNA and build our product portfolio and other adjacent high-value areas. We are putting our strong cash flow to work with organic investments in our facilities, human capital, and product innovation.

We will also continue to look for opportunities for inorganic investment to bolster our market position and provide our customers with additional solutions. We are committed to building a strong foundation for long-term, sustainable growth of our base business and will continue to focus on people, innovation, and operational excellence as our three strategic pillars. I would now like to turn the call back over to Rob to open the line for your questions. Rob?

Questions & Answers:

Operator

[Operator instructions] Your first question comes from the line of Conor McNamara from RBC Capital Markets. Your line is open.

Conor McNamara -- RBC Capital Markets -- Analyst

Oh, hey, guys, thanks for taking the question. I appreciate it. And -- and thanks for all the color on CleanCap costs.

Carl Hull -- Chief Executive Officere

Thank you, Conor.

Conor McNamara -- RBC Capital Markets -- Analyst

I think some of those slides were very helpful on the CleanCap cost and total production costs. So, thank you for that. I've got one financial question and one kind of business question. So, first, on the $20 million revenue hit, Kevin, can you maybe parse out where's that coming from? Because you did call out some inventory normalization in the press release and you talked about some biotech slowdown.

So, just which customers and kind of where that impact falls, I'll start there. 

Kevin Herde -- Executive Vice President, Chief Financial Officer

Yeah, thanks. Yeah, thanks. Conor. I would say, you know, we currently are seeing softness sort of in both the businesses.

I would say what we thought was going to be sort of contained more probably the first quarter has trickled in here to the second quarter. I think now we've seen our biologic safety testing business probably more in the mid-single-digits growth for the year and then the base business probably more in the mid-teens. So, I think you're seeing a few hundred basis points to up to 500 basis points kind of coming out of both of those full years and really just reflecting kind of what we're seeing here in the current quarter being Q2 as opposed to our original expectations and the ones we shared on our last call.

Conor McNamara -- RBC Capital Markets -- Analyst

Got it. Thanks for that. And then, just on the GMP customers, can you just help clarify? I think the last time you shared that was Q3 2022, and if I remember, the customers number was higher. So, I don't know if that's just programs falling out of the clinic.

Or can you just comment on how that -- how that number progresses and how we should think about that? Because you went from 55 to 61. I think the number was higher than that.

Carl Hull -- Chief Executive Officere

I honestly don't recall, Kevin, and I don't know if you have in front of you, or Deb, anything that would give us some color there.

Conor McNamara -- RBC Capital Markets -- Analyst

No, I'm just curious if that's like net customers because I'm assuming you have customers that go into the clinic and customers that come out as programs maybe don't reach the next endpoint. So, I was just curious if there's a way to think about kind of the progression of that and if it's seasonal or anything like that.

Carl Hull -- Chief Executive Officere

Kevin?

Conor McNamara -- RBC Capital Markets -- Analyst

Yeah, it's not -- no big deal. I was just --

Kevin Herde -- Executive Vice President, Chief Financial Officer

Yeah, look, I think the GMP mRNA CleanCap customers are 61. That is up from where we were a year ago. I think it was closer to 58 at that point in time. And then, in the clinic, we have 26 that we're currently tracking.

That's roughly the same number it's been for a few quarters now. And again, I don't -- just because you really haven't seen too many people move out of the preclinical phase into the clinical phase, at least in our pipeline, and then obviously, not too many people exit as we still just have really the one product on market. So, you know, there's not really a lot of churn in there right now. I'd say it's just sort of a slow progression of those two pipelines.

Conor McNamara -- RBC Capital Markets -- Analyst

OK. Can I sneak one more in? I'm sorry. Just on the M6.

Carl Hull -- Chief Executive Officere

Sure.

Conor McNamara -- RBC Capital Markets -- Analyst

Thanks, guys. On the M6, Is that -- does that expand the TAM? Does that give you more potential markets to go after? Does that just make you a lot more competitive in the market as you call on customers?

Carl Hull -- Chief Executive Officere

Well, I think, right now, we're focused on competitive share gains using M6, and we think that that will go directly against the enzymatic capping methods. And the bottom-line reason for that is that with an increase in yield and, effectively, protein production capability for equivalent amounts of mRNA, that will get everybody's attention even if they've been longtime users of enzymatic methods. And if enzymes and the original CleanCap were relatively close, then it was easy for them to stay with the enzymatic methods. I think with this substantially improved performance, it will make them take a much more serious look at CleanCap than they might have before.

Conor McNamara -- RBC Capital Markets -- Analyst

Got it. Thanks, you guys. Really appreciate the time.

Carl Hull -- Chief Executive Officere

You bet.

Operator

And your next question comes from a line of Catherine Schulte from Baird. Your line is open.

Catherine Schulte -- Robert W. Baird and Company -- Analyst

Hey, guys, thanks for the questions. I guess, first, you know, you highlighted a couple customer examples in terms of the ramp of sales over a four-year period, and that's clearly a meaningful driver for you as programs progress. But I was wondering, you know, for guidance for this year, if we look at your base NAP guidance, is there a way to think about how much of that is being driven by new program starts versus programs you're already involved in that are ramping up?

Carl Hull -- Chief Executive Officere

Well, Catherine, it's a good question. I think Kevin can comment on -- on his view and I'll fill in afterwards.

Kevin Herde -- Executive Vice President, Chief Financial Officer

Yeah, thanks, Catherine. I would say that, at this stage, most of what we're seeing is really the progression, I'd say, of the existing customer base. And that really goes, you know, to our -- to our strategy of really locking in the base technology as early as we can and then growing with these customers, both from a phase perspective as well as a shared wallet perspective, as well as the migration from RUO to GMP level products. And that's really our focus.

So, embedded in our guidance is really that existing customer base. It does not incorporate picking up really meaningful additional customers that haven't been part of our customer family thus far.

Carl Hull -- Chief Executive Officere

Yeah, and I would just simply add, Catherine, that given the size of orders from customers in their initial year or two as they go through the discovery process, those are relatively less significant to us than the growth of those programs as they progress down the road. And that you can see in both of those customer examples.

Catherine Schulte -- Robert W. Baird and Company -- Analyst

Yeah, OK, got it. And then, on EBITDA margins, you know, if you're expecting to reach about 39% for the full year at the midpoint of the guide, should we anticipate exiting the year more like in the mid-40s if we think about the back-half ramp? And is that a fair way to think about the starting point for '24?

Kevin Herde -- Executive Vice President, Chief Financial Officer

Yes, certainly, that is what the guidance would imply, we would be back up in that, you know, 40% to 50% level here and particular -- potentially at the higher end just given the assumption of the additional COVID revenues in the fourth quarter. You know, frankly, from where we're sitting, it's really a revenue contribution kind of over our assembled workforce and facility infrastructure. You'll see here, even in a low quarter, I think we had 30% margin, which is slightly above our pure average as I went into some detail. But the nice thing about what we have here is certainly we have a great control of our costs, really well-defined inputs, and, you know, facilities that will enable us to rapidly expand that margin as the revenue base increases.

So, you know, that's really going to be a function of what that revenue number is when we go into 2024. And, you know, as we model our business long term, certainly that margin expansion is a big part of that modeling exercise.

Catherine Schulte -- Robert W. Baird and Company -- Analyst

All right, Great. Thank you.

Carl Hull -- Chief Executive Officere

Thank you, Catherine.

Operator

And your next question comes from the line of Matt Sykes from Goldman Sachs. Your line is open.

Matt Sykes -- Goldman Sachs -- Analyst

Hey, good afternoon. Thanks for taking my questions. Maybe if I could just kind of dig into one of the previous questions, just about the softness that you're seeing into Q2. Just there's obviously a couple a number of headwinds, you know.

Whether it's emerging biotech spend or inventory overhangs, we just love to get a little bit of additional color if it's one or the other or both just so we can help kind of frame our modeling. Given that both of these probably have a finite end, we just want to make sure that we're understanding the dynamics of that softness and the sort of duration of it.

Carl Hull -- Chief Executive Officere

Matt, I really don't think we've got anything to add to the eight or ten guys that have already reported this quarter. I think our experience is the same. There are slight differences in different parts of the business. So, you might have had some -- or you definitely had some inventory build on the COVID side of the business, which everybody has reflected who's been involved in the COVID vaccine production.

And in other places, you might see more softness related to CDMO growth rates or, you know, the China recovery. So, all of those things are part of it. I can't call out one more than the other that's significant. Kevin, I don't know if you want to take a shot at that.

Kevin Herde -- Executive Vice President, Chief Financial Officer

I think that's -- that's spot on, Carl. I think, you know, we're seeing a multitude of factors, very hard to parse out the individual contributors each. But at this stage, I think we certainly see at least some of the China impact and the inventory burn-off is being temporal. And obviously, I'm rolling off here in the first half based on our guidance.

From then, it's going to come down to the -- certainly the underlying demand from the existing customers. And as we continue to look at the customer base and how that's growing, you know, the number of programs and how that's growing, as well as, you know, the additional products that we have and capabilities, I think we feel good about our ability to build once those -- once those headwinds kind of subside going into the second half and into '24.

Matt Sykes -- Goldman Sachs -- Analyst

Got it. Thank you. I appreciate it. And then, just my next question is just if you look at the Flanders build-out, you know, phase 1 complete and then completing the other one in the -- in the second quarter.

I know in the past that there's been some customers who have not been able to transition to GMP or have not -- you've not been able to transition with them. In terms of closing that gap and being able to solve for GMP production for what you're doing in RUO, do you feel that once we get through sort of the fully complete Flanders facility that you'll have alleviated a lot of those issues that you might have had in the past with some of those customers?

Carl Hull -- Chief Executive Officere

Well, why don't we ask Becky Buzzeo to comment on that from her dual roles, both on the services side of the business as well as the commercial side? Becky?

Becky Buzzeo -- Senior Vice President, Chief Commercial Officer

Hi. Thanks, Carl. Yeah, so in our facility today, you know, we do both the RUO and the phase 1 manufacturing of the mRNA. And we do believe, with the addition of our Flanders 2 facility, that we'll be able to meet customer needs who want to go beyond phase 1.

So, that is the intent of our Flanders 2 building is to go into late-stage manufacturing and have the ability to really tech transfer those clients over very easily. And it's only a couple miles up the road here and, you know, have a nice strong MSAT team to do that tech transfer and be able to follow the journey of that molecule into late-stage manufacturing.

Matt Sykes -- Goldman Sachs -- Analyst

Got it. Thank you very much. Appreciate it.

Carl Hull -- Chief Executive Officere

Thank you, Matt.

And your next question comes from the line of Dan Leonard from Credit Suisse. Your line is open.

Dan Leonard -- Credit Suisse -- Analyst

Hey, thank you. So, my first question. The decremental EBITDA margins on the $20 million reduction in your revenue forecast are pretty steep. It suggests that the change in sales forecast is fully dropping through.

Can you clarify whether that's accurate and that you're not taking any countermeasures in response to the change in sales forecast? Or are there other moving parts to consider?

Kevin Herde -- Executive Vice President, Chief Financial Officer

Yeah, thanks, Dan. I think, specifically, the midpoint of the revenue decline was about $20 million, I believe, at the midpoint of the adjusted EBITDA guidance, about 15. So, it's about 75% of that dropping through. And really that just goes to some of the things I mentioned previously.

We have a very high variable contribution margin. That's great when things go up, it's a little more painful as things go down. But that's just sort of the nature of what we have here. We don't have a lot of variable costs sort of below the -- the gross margin line.

And, you know, from our perspective, a lot of what we're investing in is really for the future, and we're going to continue to do so. So, if you look at our investments in innovation, a lot of which you saw some of the fruits of which we're here with them, six, additionally, the commercial build-out which is incredibly important to us as far as, you know, driving and seeking and realizing that long-term growth rate by making sure we get all the customers we can globally adopting CleanCap and using our products and services is a commitment and investment we're committed to. And then, lastly, the finish up of the facilities footprint, again, something we started a couple of years ago, we think, is -- is critical to our strategy as we move forward. So, you know, as you see the revenue line move, you're going to see a high proportion of that impact our adjusted EBITDA just because of the lack of below-the-line variable costs.

Dan Leonard -- Credit Suisse -- Analyst

I appreciate that. And then, my follow-up question, Kevin, is on the phasing of the year on both revenue and margins. Did I hear correctly that the COVID CleanCap expectation for Q4 is around $75 million? And if that's the case, what are the implications for margin phasing throughout the year?

Kevin Herde -- Executive Vice President, Chief Financial Officer

That is not what we said, I do not believe, no. What we said was we anticipate about another $10 million or so of COVID-related CleanCap contributions here in the second quarter. We also mentioned that between what is shipped and what is committed, we have about 65% of our $100 million guidance in the book. And then, the remainder, which would imply roughly $35 million would likely be in the fourth quarter.

Dan Leonard -- Credit Suisse -- Analyst

So, I was taking the 100 and minusing 15 in Q1 and the expectation of 10 million in Q2, so 75 million remainder, plugging that into Q4, that's not what you were seeing?

Carl Hull -- Chief Executive Officere

In the back half. It would be in the back half.

Kevin Herde -- Executive Vice President, Chief Financial Officer

Yeah, and then -- it would be in the back half. I would say that some of that committed 65% is shipping in the third quarter as well.

Dan Leonard -- Credit Suisse -- Analyst

OK.

Kevin Herde -- Executive Vice President, Chief Financial Officer

More referring to the delta between the 65 -- 65 million roughly in the 100 million, which we would be anticipating that would spike up in the fourth quarter part of the -- of the year.

Dan Leonard -- Credit Suisse -- Analyst

Got it. Thanks for clarifying.

Kevin Herde -- Executive Vice President, Chief Financial Officer

Sure.

Carl Hull -- Chief Executive Officere

You bet. Thank you.

Your next question comes from the line of Dan Arias from Stifel. Your line is open.

Dan Arias -- Stifel Financial Corp. -- Analyst

Afternoon, guys, thanks for the questions. Carl, appreciate the update on the number of customers that you now have in the mix here. Is there anything you can say about that increase if we just separate out the non-COVID accounts or maybe even the vaccine accounts entirely? Just trying to get a sense for the way in which things are tracking in some of these emerging areas that are -- that are obviously a big focus for people.

Carl Hull -- Chief Executive Officere

Well, the only thing I would say is that we're obviously not seeing new COVID accounts, that's for sure, but we are seeing continued activity from the existing players that we've been servicing at various stages along the way. So, obviously, the biggest is the Pfizer-BioNTech program, but there are a number of others beneath that. It's hard in many cases, though, for us to truly separate what is the therapeutic application versus the vaccine application. So, we've spent most -- and the reason for that is that the same company's doing both, right? All you have to do is to look at the pipelines of guys like BioNTech, CureVac, Pfizer, or others.

You'll see that they're trying to leverage that platform technology across multiple different shots on goal. So, it is hard for us to know with certainty there. We've spent a lot of time assessing those that are doing just COVID, and we think we've got a good feeling for that, but there's still some imprecision in those numbers.

Dan Arias -- Stifel Financial Corp. -- Analyst

OK, OK. And then, maybe on safety testing, biologic safety testing, Kevin, you mentioned expecting some normalization in China in the back half. Does that mean that we should think about sort of steady acceleration for BST across the quarters, or is it better to focus on back-end loading in order to get to that? I believe it's a mid-single-digit number that you talked to for the year.

Kevin Herde -- Executive Vice President, Chief Financial Officer

[Inaudible]

Carl Hull -- Chief Executive Officere

Yeah. Why don't we let Trey -- Kevin, why don't we have Trey to comment on the commercial side, and then you can back it up with the numbers?

Trey Martin -- President, Biologic Safety

Yeah, sure. Thanks, Carl. We -- we are, as so many others have been, seeing softness generally across the geos. We've reported the China softness that really started in the second half of '22.

But we are getting some encouraging signs from customers -- industry here that that will see a climb out of that. So, in our mind, it's definitely not a matter of if but when. And we're optimistic for recovery back to what we would consider to be the expected market growth rates in the second half, which averages out to the mid-single digits that Kevin called out.

Dan Arias -- Stifel Financial Corp. -- Analyst

OK. OK, guys. Thanks.

Carl Hull -- Chief Executive Officere

Kevin, anything to add there?

Kevin Herde -- Executive Vice President, Chief Financial Officer

No, I agree. I think Trey summed it up perfectly.

Carl Hull -- Chief Executive Officere

Yeah.

And your next question comes from the line of John Sourbeer from UBS. Your line is open.

John Sourbeer -- UBS -- Analyst

Good evening and thanks for the question. I guess it's -- on the base nucleic acid segment, I was wondering if you could break down even a little bit more there on what percentage of those customers are pre-revenue biotech. And, you know, is that really where you're seeing this slowness, or is it -- is it more broad-based within -- within that -- that for the updated guidance?

Carl Hull -- Chief Executive Officere

Yeah, John, I would say that, as we've commented I think a couple of times in the past, we don't see any of the pre-revenue biotech customers just completely shutting down programs and running away. They have, in some cases, reduced the number of programs that they're going after or reprioritize those to focus on -- to focus their resources on fewer numbers of programs to manage their burn rates. But it's not like we're seeing pre-revenue biotech companies just shut down and run away from mRNA if that's been their focus.

John Sourbeer -- UBS -- Analyst

And have you quantified, you know, what percentage of revenues that would be?

Carl Hull -- Chief Executive Officere

We have a couple of cuts at it. As you might imagine, we have to do not only our own work on our book but some primary research. I would say the numbers I have seen today are a little bit immature, and I actually wanted to hold off to get a little bit better and more comfortable insights until the next quarter. So, we think we'll have something for you by then.

John Sourbeer -- UBS -- Analyst

Great. And then, you know, just one last one here.

Carl Hull -- Chief Executive Officere

Sure.

John Sourbeer -- UBS -- Analyst

You mentioned a couple of times, I think, in the prepared remarks, looking to do something inorganic. You know, any just additional color on where you think there's opportunities to fill in, you know, should be something similar kind of to some of the tuck-in deals that you've done over the last year?

Carl Hull -- Chief Executive Officere

Yeah, look, I mean we're super happy with the Alphazyme team and delighted to have them as part of the organization. I think that fits the historical model of Maravai exceptionally well. I think we will continue to look for those gems when we can find them. And then, we're trying to be a little bit more creative when there may not be a number of assets currently on the market or at prices that we would consider to be reasonable to look at deals that might be slightly more complex but can involve the carve-out of businesses of other companies and/or, you know, unique structures that could fold some businesses into us.

So, I think you may see a little bit more creativeness in deals. Hopefully, they'll be a little bit larger in size in terms of immediate revenue contribution, but Alphazyme still remains an example of our sweet spot.

John Sourbeer -- UBS -- Analyst

Thanks for taking the questions.

Carl Hull -- Chief Executive Officere

You bet.

And your next question comes from the line of Tejas Savant from Morgan Stanley. Your line is open.

Tejas Savant -- Morgan Stanley -- Analyst

Hey, guys, good evening, and thanks for the time here. Carl, Kevin, I want to go back to an earlier question right at the top of the call, actually, you know, around those GMP customers with a NAP. So, I think the question is basically that, you know, in 3Q, you had about 68 of them, today you've shown 61. So, perhaps can you just bridge us to the number of customers you have today versus last fall? It's an important metric for a lot of investors in light of the loss of business you've highlighted here that you not having GMP ahead of Flanders.

So, just any context, color, or bridge you could provide would be helpful.

Carl Hull -- Chief Executive Officere

As I said, Tejas, I don't have the numbers in front of me, so I can't.

Tejas Savant -- Morgan Stanley -- Analyst

Got it. OK. Then perhaps on biologics safety testing, you highlighted this, you know, the International Conference in Harmonisation guideline change. Over what time frame do you expect that to be meaningful for your business if all goes to plan? And on the other side of that, I mean, as they think about sort of, you know, this guideline update, how disruptive could it be for customers who are, you know, already using sort of alternatives? Or is that sort of not really a consideration?

Carl Hull -- Chief Executive Officere

Well, look, I think that it can be very disruptive mainly because of the costs and risks associated with late-stage viral clearance testing the way it's currently practiced. So, you bet everything on your final test of that. And at the end of the day, if you fail that test, then you have to go back to development of your processes in such a way that it will mediate the problems that you saw in a go around. And that could add months, if not years, to a development program.

So, we think that the availability of -- of the product, coupled with the discussion about the guideline changes, comes really at a perfect time. And even if customers are not immediately incented to change their historical gold-standard final clearance testing, they should certainly be very interested in utilizing the kit along the way as a surrogate marker for whether they might have a product at the end of the road.

Tejas Savant -- Morgan Stanley -- Analyst

Got it. That's helpful. And then, last one for me. Carl, I know you mentioned you want to hold off until the next quarter on your SMID-Cap biotech exposure.

But just, you know, anecdotally, as you talk to your salespeople, any color you can share on for how many of these your existing customer base is raising money here in the next 12 months or so, you know, something that's -- that's you know, front and center on their radars? I know you've talked in the past that a lot of these customers raised a lot of money during the pandemic given the excitement around mRNA, but just any updates around those conversations would be helpful.

Carl Hull -- Chief Executive Officere

Yeah, no, we have certainly not seen new money come in, Tejas, if you're looking at it from that perspective because of the obvious factors that have been going on over the last 18 months. So, I think the demand that we're seeing here is from pre-established companies who raised a significant amount of capital during that period of time we talked about. Are they husbanding that capital a lot more than they were? Probably, yes. And are they less certain about their ability to get another round done? That would be certainly yes.

So, I think that it's a mix, but we were fortunate that there was a very wide-open window in that sort of, you know, 2020, 2021 time frame and that's still sustaining us. Others may have a little bit of a different exposure. And particularly, if you're thinking about biologics or small molecules, that trajectory appears to be different than the cell and gene therapy world.

Tejas Savant -- Morgan Stanley -- Analyst

Got it. Super helpful. I appreciate the time and all the color, Carl. Thank you.

Carl Hull -- Chief Executive Officere

You bet, Tejas. OK, Rob, I think that's about it in terms of our timing today. So, perhaps if you'd like to turn the call over to Deb.

Operator

Certainly. I will now turn the call over to Deb Hart for some final closing remarks.
