Codexis believes fully enzymatic nucleic acid synthesis will offer certain improvements over phosphoramidite chemistry, including with respect to required infrastructure investments, batch size limitations and waste disposal challenges. The company demonstrated gram-scale synthesis with the ECO Synthesis™ manufacturing platform in December 2023 and expects to begin pre-commercial customer testing in 2024, followed by early commercial licenses in 2025 and a full commercial launch in 2026.

Financials

Codexis has a history of net losses, reporting a net loss of $76.2 million for the year ended December 31, 2023. The company's annual revenue for 2023 was $70.1 million, and it generated negative operating cash flow of $52.6 million and negative free cash flow of $57.1 million during the same period.

In the first quarter of 2024, Codexis delivered strong financial results, with total revenues of $17.1 million, a 32% increase compared to the first quarter of 2023. Product revenue increased by 14% to $9.6 million, while research and development revenue grew by 63% to $7.5 million, primarily due to a $6.0 million license agreement with Roche. The company's product gross margin improved to 49% in the first quarter of 2024, compared to 46% in the same period of the prior year.

Codexis' research and development expenses for the first quarter of 2024 were $11.2 million, a decrease of 32% compared to the first quarter of 2023, while selling, general and administrative expenses declined by 16% to $12.9 million during the same period. The company's continued focus on expense management has resulted in a similar run rate across R&D and SG&A expenses compared to the fourth quarter of 2023.

Geographical and Revenue Breakdown

Codexis' revenues are primarily generated from three geographical regions: APAC, the Americas, and EMEA. In the first quarter of 2024, the company reported revenues of $7.3 million from APAC, $7.2 million from the Americas, and $2.6 million from EMEA.

The company's product revenue is diversified across several categories, including its three major commercial pharmaceutical manufacturing products, enzyme supply and other commercially approved products, generics, programs in clinical trials, and life sciences and other programs. In the first quarter of 2024, the three major commercial pharmaceutical manufacturing products accounted for 37% of product revenue, down significantly from 72% in the first quarter of 2023, reflecting Codexis' progress in diversifying its revenue base.

Guidance and Outlook

Codexis is confident in reiterating its 2024 revenue guidance range of $38 million to $42 million. The company expects product revenue to be lowest in the second quarter of 2024, at approximately 60-70% of the first quarter level, followed by a stronger second half of the year. This includes the recognition of a large customized double-stranded RNA ligase order from a pharmaceutical customer by the end of 2024.

Research and development revenue is expected to be weighted towards the second half of 2024, as new development programs get off the ground. Excluding revenue accounting related to tax credits, Codexis projects that its full-year 2024 revenue will be weighted approximately 40% for the first half of the year and 60% for the second half.

The company ended the first quarter of 2024 with $85 million in cash, cash equivalents, and investments, which it expects will fund its planned operations through positive cash flow, anticipated around the end of 2026.

Technological Advancements and Competitive Positioning

Codexis is making significant technical progress in its ECO Synthesis™ manufacturing platform, and the company is on track to demonstrate the enzymatic synthesis of a full-length RNA molecule at the upcoming TIDES USA meeting in May 2024. This milestone will enable Codexis to showcase the viability of its platform and the ability to synthesize the same oligonucleotides that its customers are actively developing for RNAi therapeutics.

Beyond the synthesis of full-length oligonucleotides, Codexis is also advancing its efforts to engineer innovative solutions for the enzymatic synthesis of input materials, such as nucleoside triphosphates (NTPs) and starter oligonucleotides, as well as the enzymatic incorporation of targeting moieties. These advancements have the potential to lead to better, cheaper products by reducing associated costs and improving product quality.

The company's double-stranded RNA ligase program is another key area of focus, as it allows Codexis to offer customized, high-performance enzymes that can be efficiently integrated into its customers' manufacturing processes. The company's ability to leverage its extensive database of ligase variants and corresponding activity data enables it to streamline the process of identifying and optimizing lead enzymes for its customers.

Codexis believes its versatile and modular approach to enzymatic oligonucleotide synthesis will provide fundamental value to players in the RNAi therapeutics market, where traditional chemical synthesis methods face resource and capacity constraints. The company's valuable intermediates developed for the oligonucleotide synthesis market could also be applied to other growing modalities in the RNA space.

Risks and Challenges

Codexis faces several risks and challenges, including its history of net losses, the highly regulated and expensive nature of biotherapeutic programs, its dependence on a limited number of customers and products, and the potential for the termination or expiration of patent protection for its customers' active pharmaceutical ingredients to materially and adversely affect its revenues.
