2019 First Quarter

Analyst/Investor Conference Call

May 8, 2019

Prepared Remarks of Dr. Stephen S. Tang and Roberto Cuca

Please see “Important Information” at the conclusion of the following prepared remarks

Introduction – Steve Tang

Thank you Jeanne. Good afternoon everyone and welcome to our call.

I’m pleased to report that our first quarter revenues and bottom line performance fell within the financial guidance we announced during our last earnings call and represent a good starting point for the second quarter and full-year 2019. Our innovation-driven growth strategy is working and delivered many positive developments, during the quarter, that we will detail later in the call.  We remain confident in our strategy and our ability to execute against our strategic priorities.

During our last call, we reported that a large consumer genetics customer had recently adopted a new promotional strategy and, as a result, reduced its purchase forecast for the year.  While that unfortunate development had a measurable effect on our Q1 results, it is important that we not let that event obscure the significant positive progress underlying our business. For example:

As you can see, we are enthusiastic about this quarter and our future. The foundations of our business are strong, and we are seeing growth in the areas in which we have targeted and invested. Importantly, we are on the right path with our innovation-growth strategy despite the negative effect on near-term revenue by the new market approach of a large customer.

Looking ahead, we expect the underlying strength of our infectious disease testing and molecular solutions segments will be more fully demonstrated as the year progresses.

Turning briefly to the quarter, the decline in our revenues compared to the first quarter of 2018 was primarily the result of the reduced purchases by that large customer I mentioned earlier and some unevenness in the timing of customer orders for our OraQuick ^® HIV Self-Test in international markets .    Nonetheless, we delivered Q1 results within our expectations.

Beyond the first quarter, we expect strong molecular growth outside of the one large consumer genetics customer. We expect sales to this customer will be consistent with its annual minimum contractual purchase obligation. This, combined with continued growth in our global infectious disease testing business, will drive solid financial results and gives us the confidence to issue full-year guidance. Our guidance for Q2 and the full year reflects the continued success we anticipate as we further execute our growth strategy.

With that, let me now turn things over to Roberto for his financial review.  I will then follow up with some additional insight into the trends and factors that help validate our strategy and that are expected to benefit our business for the remainder of 2019 and beyond.

First Quarter 2019 Financial Results – Roberto Cuca

Thanks Steve, and good afternoon everyone.

Our first quarter net revenues decreased 28% to $30.1 million from $41.9 million reported in the first quarter of 2018. Our net product revenues decreased 26% to $28.3 million compared to the prior-year period.  As Steve just described much of this decrease was driven by the changed market approach of a single large consumer genetics customer and the uneven distribution of the strong international HIV sales we expect over the course of the year due to ordering patterns.

Our molecular net revenues including other revenues decreased 40% to $11.9 million in the first quarter compared to $20.0 million in 2018.  Royalty income declined 32% to $1.1 million in the first quarter of 2019, from $1.6 million in the same period of 2018.  Molecular product revenues decreased 42% to $10.6 million in the first quarter of 2019 compared to $18.4 million in the first quarter of 2018. Sales of our genomic products declined 53% to $8.1 million largely due to the lower sales to a large consumer genetics customer as previously described.  Microbiome sales

3

increased 83% to $2.3 million from $1.3 million in the first quarter of last year due both to organic growth as well as the inclusion of lab service revenues generated by our newly-acquired subsidiary CoreBiome.

Domestic HIV sales decreased 14% to $4.3 million in the first quarter of 2019 compared to $5.0 million in the first quarter of 2018 largely due to decreased sales of our OraQuick ^® In-Home test and lower sales of our professional product as a result of continued product and price competition.

International HIV sales decreased 30% to $4.0 million from $5.7 million in the first quarter of 2018 due to customer ordering patterns partially offset by higher sales of our HIV Self-Test into Asia. Quarter-over-quarter variability in volume is expected as the programs utilizing our Self-Test continue to create awareness and assess on-going demand.

Domestic HCV sales increased 12% in the first quarter of 2019 to $1.8 million from $1.6 million in the prior-year period largely due to increased government funding that is allowing for the expansion of existing HCV testing and treatment programs and the addition of new programs.

International HCV sales in the first quarter of 2019 increased 119% to $1.5 million from $665,000 in the same period of 2018 primarily due to continued growth in Asia as well as customer ordering patterns.  

Other revenues were $1.8 million in the current quarter compared to $3.7 million in the prior year.  The decrease is largely due to lower royalty income and decreases in BARDA funding and cost reimbursement under our charitable support agreement with the Gates Foundation.  The reduced BARDA funding in an indication that we are wrapping up the work under this program and rotating R&D resources to projects that are aligned with our long-term growth strategy.

Gross profit percentage for the first quarter of 2019 was 60% compared to 58% reported for the first quarter of 2018.  Gross profit percentage for the current quarter benefited from improved product mix associated with an increase in higher gross profit percentage product sales and lower royalty expense partially offset by the decrease in other revenues which contribute 100% to the gross profit percentage.

4

Our operating expenses for the first quarter of 2019 were $21.9 million compared to $25.0 million in the comparable period of 2018.  Operating expense in the first quarter of 2019 included $1.3 million of non-cash acquisition-related contingent consideration costs, incremental operating expenses generated by CoreBiome and Novosanis, and $597,000 of acquisition-related transaction costs. There were no similar acquisition-related costs in the first quarter of 2018.  The first quarter of 2018 included $6.4 million of transition costs associated with executive management changes that occurred during that period.   There were no material transition costs in the first quarter of 2019.   

In the first quarter of 2019 we recorded an income tax benefit of $29,000 compared to income tax expense of $2.0 million in the same period last year.  The decline in tax expense reflects the lower pre-tax earnings generated by our Canadian subsidiary and the results generated by Novosanis.  

We reported a net loss of $3.3 million, or $0.05 per share, for the first quarter of 2019 compared to a net loss of $2.1 million, or $0.03 per share, for Q1 2018.

We continue to maintain a solid cash and liquidity position.  Our cash and investments balance at March 31, 2019 was $183.6 million compared to $201.3 million at December 31, 2018. During the first quarter of 2019 we used $13.3 million of cash to acquire CoreBiome and Novosanis.  Cash generated by operating activities during the first quarter of 2019 was $528,000 compared to $7.6 million in the same period of 2018.

Turning to guidance:  For the second quarter of 2019, we are projecting revenues of $40.0 to $42.0 million and net income of approximately $0.02 per share.  For the full year of 2019, we are projecting revenues of $170 to $175 million and net income of $0.22 to $0.24 per share. These projections do not account for the impact of changes in the fair value of acquisition-related contingent consideration or potential business development transaction costs since the full extent of those items cannot be determined at this time.

And with that I will now turn the call back over to Steve.

Business Update – Steve Tang

Thanks Roberto.   I’d now like to share with you some key market trends in our M olecular and I nfectious D isease business es that substantiate our strategy and support our guidance. Let me first discuss our M olecular business, which will continue to be a key driver of our overall business.

Molecular Solutions – Steve Tang

Human Genomics

The genetic testing market has been the largest component of our overall molecular business for some time, and continues to evolve.  Given the importance of the genetic testing market to our business, I would like to describe some of the trends we are seeing based on a combination of data analysis, customer feedback and market research we recently conducted.  Of most interest are the market dynamics affecting two areas within genetic testing.  They are ancestry and disease risk management.  

Ancestry testing consists primarily of genetic tests that provide consumers with genealogical information.  This is the largest and most developed component of the genetic testing market.  Historically, the growth in ancestry testing seems to have been strongly tied to advertising spend and promotional pricing offered by the leading direct-to-consumer companies.  It appears that the ancestry market in the United States is maturing. As such, we expect to see the growth rate of that subsector of the overall genetic testing market slowing, and likely leveling off in the next couple of years.  

Outside of the U.S., however, we are seeing, and expect to continue to see, significant growth in genetic testing.  As previously noted, the Asia-Pacific market is at a much earlier stage than the U.S. market.  Our market analysis suggests that it may be as much as five years behind the domestic market, so there is much room for us to grow.  In Q1, although the dollar amount is relatively low, we saw our sales increase 231% in Asia when compared to the first quarter of 2018.  This type of growth reflects increased product offerings, new market entrants and the expansion of existing customers, like WeGene, into new geographies in Asia.  Given the early stage of this market, we expect continued robust growth for the foreseeable future.

The other key submarket of genetic testing is disease risk management, which encompasses genetic tests that provide information about an individual’s genetic health risk.  Examples include an individual’s predisposition to diseases such as cancer and carrier status.  Pharmacogenomics

6

and companion diagnostics are also included in this submarket.   We are seeing a steady increase in the number of new customers in this area and consistent growth as companies are add ing to their test menus a nd increasing their test volumes .  We believe that uptake in this market will be highly dependent on practitioner awareness and consumer awareness of emerging patient-initiated testing models.   Given the increasing focus on personalized medicine, we see much potential for growth in disease risk management.  

We currently count several pioneering companies in this space as customers.  One example of such a customer is Helix which recently announced an increased focus on enabling population-based health studies such as the Healthy Nevada project.  This study, which has enrolled over 35,000 participants since its launch two years ago, has just been expanded to the entire state of Nevada, with a goal of becoming a nationwide model.  We are proud of our relationship with Helix and believe we are uniquely qualified to serve this market thanks to our leadership position in DNA collection, our focus on high quality products, and our FDA and other global regulatory clearances.  

Moreover, with the addition of Novosanis’ Colli-Pee ^TM collection device, which is designed to collect first-void urine samples, we are now able to expand the types of specimen collection kits we offer to serve new markets including the sexually transmitted infection and cancer screening markets.  An increasing number of testing guidelines are including first-void urine as a recommended specimen type.  In particular, urinary Human Papilloma Virus (HPV) detection is an alternate sampling method to improve cervical cancer screening participation.

These trends are already positively impacting our genomics business.  For example:

7

Finally, there are other parts of the consumer genetic testing market that are expected to grow, but today are only small contributors to our business.  These include lifestyle testing, which uses genetic tests to provide lifestyle information around metabolism, fitness, health traits and entertainment, and companion animal genetic testing.  We believe these areas, as well as others that will undoubtedly emerge, could become meaningful contributors to our business.

Microbiome

If you have been following OraSure, you know that we have highlighted the similarities between trends in the microbiome research market and the early days of genetic testing. That similarity continues.

In the microbiome market we delivered another record performance with first quarter revenues up 83% when compared to 2018.  This reflects a 30% increase in sample collection kits shipped and a 56% increase in first-time purchasers of our kits when compared to the prior year quarter.  Both of these metrics support our view that the recent strong growth in this market is likely to continue for the foreseeable future.  As we have learned from our human genomics experience, new customers tend to start with small volumes of devices as they validate their study and lab protocols, and then expand their studies as new funding becomes available.

Diversification of our microbiome offerings remains a key focus.  We intend to continue expanding our collection kit offerings to include different specimen types, such as skin, in addition to stool, for microbiome analysis.  With the acquisition of CoreBiome, additional opportunities are also opening for microbiome analysis, including not just human microbiome tests but also environmental and agricultural testing.  Approximately 60% of CoreBiome’s customers are currently in the area of pharmaceutical discovery and clinical trials.  We expect that pharmaceutical customers will continue to be important, early adopters of advanced multiomic data analysis.  In fact, during the first quarter CoreBiome entered into a contract with a significant new customer to provide advanced machine learning for biomarker discovery.  This type of discovery is expected to help advance our understanding for optimal disease treatments.

8

We are also thrilled with the recent addition of Dr. Rob Knight to CoreBiome’s scientific advisory board.  Dr. Knight is Professor and Director for the Center for Microbiome Innovation at the University of California, San Diego, and one of the most widely cited scientists in the microbiome field.  He was a key contributor to the National Institutes of Health Human Microbiome Project, and is also a thought leader who developed many of the foundational tools underlying microbiome science.  His involvement as an advisor to our business exemplifies how we are working with field experts in our key growth areas, and further demonstrates our commitment to driving innovation in the microbiome community.

Multiomics

As previously noted, we continue to see nice synergies within our molecular business, as more of our existing human genomics customers start to move towards multiomics, by introducing a microbiome component to their studies and offerings.  In particular, we saw a 33% increase in customers who are using both genomics and microbiome kits during the first quarter of 2019, compared to the prior year quarter.  We see this trend continuing and will continue to evolve our multiomics strategy in order to maximize the potential for this emerging area in human health.

Infectious Disease Testing – Steve Tang

Turning now to infectious disease:

Our global HIV revenues were down in Q1 compared to 2018, primarily as a result of the timing of orders for our OraQuick ^® HIV Self-Test.  In particular, lower sales into Africa were only partially offset by growth in Asia.  As indicated in prior calls, the quarterly volume of self-test sales can be a bit choppy as individual countries determine their utilization of product.  This is part of the normal development cycle within this market that involves the start-up of new testing programs where awareness needs to be created and routine utilization is being determined.

However, we expect that our HIV global business will show solid double-digit growth for the full year, once again primarily driven by increased self-test revenues in subsequent quarters. We are continuing to see the HIV self-test market develop, as countries with existing programs reorder product, additional countries move from a pilot stage to full scale up for their programs, and the

9

number of country registrations for our product continue s to increase.  As previously noted, phase II of the STAR , or Self-Testing Africa, program has largely ended , and a majority of our volumes are now coming from non-STAR countries.   We expect that trend to continue.

We have also had numerous discussions with major funders of testing programs.  Although these discussions do not guarantee additional purchases, these funding organizations have signaled their intention of beginning or increasing their investment into the self-testing market.  As you may recall, we previously mentioned that UNITAID would be funding another self-testing project involving the Ivory Coast and other nearby countries.  This funding has begun and initial shipments of our test for that program occurred in Q1.  Although this program will be much smaller than the STAR program, it is a concrete example of how and where additional funding is driving growth in HIV self-testing.

Our activities under the support agreement with the Gates Foundation also continue, as expected.  We now have product registrations in 15 countries, submissions pending in an additional 17 countries and other registration applications being prepared.  We are gradually expanding our access to the 50 countries covered by the Gates Agreement, and our strategy for regulatory submissions and approvals reflects how this market is developing and growing.

All of this continues to lend support to the robust projections previously announced in a report by UNITAID and the World Health Organization, or WHO, which we discussed on prior calls.  That report suggested self-test demand would increase from 1 million tests in 2017 to an average range of 16 million tests by the end of 2020, with the higher end of that range reaching just over 19 million tests.  Along these lines, in March of this year, the Journal of the International AIDS Society published a comprehensive review entitled, “Realizing the potential of HIV self-testing for Africa: lessons learned from the STAR project.”  This report concluded that HIV self-testing has substantially developed in recent years and is now considered a critical HIV response strategy in controlling the epidemic.  The report also concluded that a new testing paradigm based in part on HIV self-testing is a key part of HIV response over the next decade and will be critical to achieving 95% diagnosis in broad geographic markets during that period. As the first WHO-prequalified HIV self-test, we are leading the way in self-testing.

10

So with what we’re seeing in our own business, coupled with the market developments I have outlined, we are quite optimistic about the continuing growth potential for our global HIV franchise.

Turning briefly to our OraQuick ^® HCV business, global revenues grew 43%, with international sales increasing 119% compared to the first quarter of 2018.  We are seeing growth primarily in Asia and Eastern Europe with the expansion of existing programs and new customers and new testing and treatment programs emerging.  

Our domestic HCV business is growing as well, with revenues up 12% for the quarter.  This growth was generally derived from the initiation of new programs and the expansion of existing programs.  Funding for this growth is coming from a combination of the Centers for Disease Control and Prevention and state jurisdictions that are finding additional funds within their existing budgets.  

As you may know, the current Federal budget included an additional $5 million in funding to manage the impact of the opioid epidemic on infectious disease, with HCV being one of the diseases specifically mentioned.  In the proposed 2020 Federal budget, an additional $291 million is being requested in order to end the HIV epidemic, and another $58 million is being requested to address the infectious disease consequences of the opioid epidemic.  So we believe more funding is likely to continue for both HIV and HCV, and will help enable the HCV franchise to continue as a growth driver and help stabilize our HIV franchise.

Conclusion - Steve Tang

So, in closing, despite the head wind from that large consumer genetics customer, our overall business is performing as we would have expected -- and even better in certain areas. Our innovation-driven growth strategy is working and we expect to continue to benefit from the large and growing markets we serve.   It should be clear from our second quarter and full-year guidance, that we anticipate a strong second half of the year. Our business is well positioned to deliver strong growth in future periods, both through acquisition and strategic execution.  We are particularly excited about the prospects for the international genomics market, the growth of the disease risk management submarket of genetic testing, particularly around population studies, and

11

our microbiome product s and services , as well as our unique ability to support the emerging multiomics market .  

Our infectious disease segment is on track and we expect significant growth from our global HIV franchise.  In addition, we see our HCV product as an ongoing contributor.

Based on our extensive market research and discussions with customers, we are confident that our best days are ahead. We believe that we have the right products, leadership team, balance sheet and business strategy in place to capitalize on the opportunities before us. It’s exciting that many of the key markets we serve are very large for a company our size, and these opportunities are still mostly in their infancy. I would also emphasize that we are not only adding new customers, due to our expanded offerings, but we are also increasing the size of our existing relationships. Importantly, we do not have another customer close to the size of the one that changed its purchasing expectations. Therefore, it is safe to assume that another disruption to our top line coming from a single customer is unlikely going forward. Lastly, we are confident we can deliver on our full-year guidance and we are committed to using our balance sheet to enhance our already attractive long-term growth prospects.

And with that, we will now take your questions.  Operator, please proceed.
