Thank you and good morning. We issued our 2023 first quarter results yesterday afternoon.
As we mentioned on our call in early March, Q1 was a challenging period. Net sales were $3.1 million, down 28% compared to the same period in 2022. While that short-term result is certainly frustrating, it's not the best method to evaluate the business.
We address multibillion-dollar industrial end markets, replacing fossil-based chemistries that have been used for many decades. We have direct relationships with the right customers to deliver significant growth, customers like SWISS KRONO, Dow and our key strategic wood composites manufacturer that is backward integrated into a leading international retailer.
The prospects we have in front of us today have never been better. In addition to progress with important existing relationships, this opportunity set is fueled by both new products and new relationships. The pipeline improved during the quarter with important progress made. Admittedly, that's not yet showing in our sales volumes. But the opportunity in front of us has not changed. It is as large as ever, and I'm confident in our ability to execute on it.
Why am I so confident? Our goal of becoming a $100 million revenue business is achievable with the customers we have in hand today. If we didn't add any new accounts in the coming years, if we went nowhere else, the opportunity set is there for us to surpass the $100 million figure with our key large accounts that each have multiple mills in their supply chains.
The opportunities are right there for us to realize on that goal, and I believe we can do it. And in fact, we have a broadening pipeline, with renewed interest on the wood composites front and continued new interest in our Surflock strength aid products.
During the quarter, the backward integrated wood composites manufacturer published its 2022 Climate Report. In it, they identified wood-based glues as 5% of their total carbon footprint. The manufacturer and retailer has identified bio-based glues as one of the critical movements in material choices within their supply chain and a key enabler of achieving their overall climate goals. That is a significant step forward in how they've positioned that goal to their supply chain and more broadly through the mainstream press.
It benefits us in 2 ways. First, the manufacturer committed to a meaningful step in its implementation of DuraBind for particleboard production at the first mill where we are operational. This step is about further industrialization and implementation beyond earlier commitments as they gained experience with DuraBind in their operation. That is great news that is not showing up in the quarter-over-quarter volumes at this point. So while this manufacturer became a meaningful account to us in 2022, we expect their volumes to step up significantly in the second half of this year.
Second, and potentially of even greater significance, the climate report and the media reports that followed it, made it clear to the retailer's supply chain partners that bio-based glues were critical to achieving its climate goals. That was a strong statement to the supply chain that the ship is sailing. Fossil-based glues are on their way out at the retailer and bio-based blues are the critical movement.
And I think that caught some of the third-party manufacturers in the industry by surprise that this much progress had been made. This international retailer is a forward-thinking thought leader in the market. When they move, it causes their supply chain and the broader industry to move. And we're starting to see that on new inbound interest in DuraBind.
In the early days of our DuraBind program, we had several prospects that went quite far in the technical evaluation of DuraBind and its use in their production processes, with largely successful results. They stopped short of moving to commercialization because they didn't see the market catalyst to warrant significant industrial change. The demand for more sustainable, healthier alternatives wasn't as evident then. That has changed with the commitment from this international retailer. They have set the tone for the market. And in the meantime, we have made significant improvements in the DuraBind product family.
We have new trial programs on the go in the second quarter. We're in a position to be more discerning about who has the capabilities and the conviction to move ahead with DuraBind. We're working with a few key prospects that we think can significantly move the needle for both the industry and for our results as well.
Later this month, we'll be attending the LIGNA conference in Germany, which is a major industry trade show and conference that takes place every 3 years. We expect that the awareness from the international retailer's commitment will drive new attention and interest in DuraBind at the event.
We are poised for greater success in the wood composites end market, and it's supporting our diversification strategy with the "multiple shots on goal" approach. It's working. While sales have remained stable the past few years, the composition of the revenue mix has changed substantially. The graphic paper end market used to make up more than 90% of our revenue just a few short years ago and almost all of our gross profit. With the industrial change we've enabled in our newer end markets, we have a good start, where today, our revenue coming from end markets outside of graphic paper is approximately half, and the contribution to gross profit is more than half.
The deterioration in the legacy graphic paper market continues. North American coated freesheet paper production was down more than 28% in Q1 versus the same period in 2022. Destocking is happening throughout the supply chain. As a result, industry operating rates have also dropped significantly over the past 6 months from 97% in September to 76% in March.
SB latex, the petroleum-based binder our EcoSphere binder replaces, remains below its historical pricing levels. These pricing dynamics, together with the cost profile of our feedstock, has EcoSphere at a disadvantage.
We made decisions in 2022 to secure sufficient feedstock to keep our key accounts in supply. That feedstock was higher cost, and it's working its way through our results. More recently, we have seen positive news on both the availability of feedstock and improved pricing than what we were seeing as recently as January, which is great.
The accounts that are using EcoSphere see the value proposition in it. The higher-priced feedstock has impacted demand, but as we work our way through that expensive feedstock and return to more normalized pricing levels, we continue to believe EcoSphere is a valuable contributor to the business.
I'm sometimes asked, "Why not just exit the graphic paper market if it's so challenged?" That is not our strategy. First, it is a good base loading level for our operations. It makes a positive contribution, more so in a normal pricing environment, but even in the recent supply-constrained situation, it is still a net positive contributor.
Second, we've established strong relationships with some of the largest pulp and paper manufacturers in the market. They rely on us. They trust us, and they are important to us as we look to broaden our reach with Surflock, our wet end strength aid.
The rollout of Surflock is moving slower than we anticipated due to general softness in the macro market, but interest in the product and the broadening of the pipeline is definitely happening. We're going into new geographies and new accounts on a monthly basis.
We have a number of key prospects in the pipeline that we have discussed before, and those prospects remain in place and remain the most important and advanced in the pipeline. But we have significantly more irons in the fire, so to speak.
Our primary go-to-market approach has traditionally been direct to manufacturers, and it's still key to us, but we've opened up another front, engaging the chemistry service providers that implement and monitor wet end chemistries at the mill level. There are a number of regional players that we're actively engaged with that could prove to be important channel partners for us over time. Our goal with them is to ensure they understand and can optimize a chemistry package that involves Surflock.
These players have a track record of excellent service to the mills right in the local environment, whether that's Eastern Europe, Japan or the U.K. We believe this group can be an important part of the go-to-market strategy in the pulp, tissue and paperboard end markets to realize the full potential of Surflock.
On the personal care side, our development and marketing partner, Dow, continues to make progress on the hair fixative end market. The results have not come as quickly as they expected. They continue to believe they can make a material impact in the market with all-natural formulations. And they've also broadened the addressable market with new formulations of MaizeCare for skin care, which they introduced at a recent cosmetics conference. Based on their feedback to us, Dow is enthusiastic about the opportunity for MaizeCare across both the hair fixative and skin care end markets.
We have the products in front of the right partners and the right customers to deliver a $100 million business. It's taking more time than we anticipated, but the opportunity set is as strong as ever, and we're confident in our ability to execute.
Now Rob will address our financials.
