Codexis Reports Second Quarter 2020 Financial Results

Revenues increased 21% to $15 million; 72% rise in R&D revenue included a significant contribution from the Takeda biotherapeutics partnership

Conference call with slides begins at 4:30 p.m. Eastern time today

REDWOOD CITY, Calif. (August 6, 2020) - Codexis, Inc. (Nasdaq: CDXS), a leading protein engineering company, announces financial results for the three and six months ended June 30, 2020 and provides a business update. Management will hold a conference call today beginning at 4:30 p.m. Eastern time, with accompanying updated Pipeline Snapshot slides available here.

“We delivered better-than-expected revenues for the quarter of $15.0 million, up 21% over the prior year, led by strength in R&D revenues which grew 72%,” said Codexis President and CEO John Nicols. “Throughout the pandemic we have continued to forge key partnerships that build toward a strong future. Our partnership with Takeda, which we announced in late March as the pandemic surged, contributed significant revenues in the second quarter. We also executed new deals with Alphazyme and Molecular Assemblies that highlighted four new Performance Enzymes that we are working to commercialize into high growth life science applications, targeting improvements to the manufacture and diagnosis of both DNA and RNA.

“Our new partnerships build upon a strong foundation backed by our highly capable team and substantial financial resources. Our updated Pipeline Snapshot now showcases 65 pre-commercial and commercial programs, a growth of 25% versus the last year, including 13 self-funded programs. The number of commercial stage programs, which generate recurring revenues for us, delivered the largest annual jump since we started providing the pipeline snapshots four years ago. We look to work with our customers and partners to continue this growing commercialization trend especially given the continued progress in over 50 advanced stage pre-commercial programs, both internal and external, being managed by the Codexis team in parallel,” Mr. Nicols said.

“In response to COVID-19, following nearly two months of lab shutdown, we gradually ramped up our R&D operations beginning in early May, by staggering work schedules and adapting our facility to provide a safe environment for all on-site employees, so that at present we are utilizing the majority of our normal R&D capacity. We currently plan to return to full R&D capacity around the end of the summer, but note that a resurgence of COVID-19 and other factors could impact that timeframe.”

Second Quarter Financial Results
Codexis is reporting two business segments: the Performance Enzymes segment, which consists of its protein catalyst and enzyme product and service offerings with a focus on pharmaceutical, food, molecular diagnostics and other industrial markets; and the Novel Biotherapeutics discovery and development segment.

Total revenues for the second quarter of 2020 were $15.0 million, up 21% from $12.3 million for the second quarter of 2019. Product revenue was $4.5 million, compared with $6.2 million for the second quarter of 2019, with the decrease due to the timing of demand for various enzymes. Research and development (R&D) revenue for the second quarter of 2020 was $10.5 million, up 72% from $6.1 million for the prior-year period, primarily due to revenues under the Novartis CodeEvolver® licensing agreement and license fees from the Takeda collaboration, partially offset by lower revenue as a result of delays attributable to the COVID-19 pandemic. R&D revenue for the second quarter of 2020 included $3.0 million from the Performance Enzymes segment and $7.5 million from the Novel Biotherapeutics segment. R&D revenue for the second quarter of 2019 included $4.3 million from the Performance Enzymes segment and $1.7 million from the Novel Biotherapeutics segment.

Gross margin on product revenue for the second quarter of 2020 was 62%, up from 56% for the second quarter of 2019 due to product mix.

R&D expenses were $10.9 million for the second quarter of 2020, compared with $8.3 million for the second quarter of 2019, with the increase primarily due to higher regulatory expenses, higher headcount and higher allocable expenses, partially offset by lower lab supplies expenses and lower outside services. R&D expenses for the second quarter of 2020 included $5.0 million from the Performance Enzymes segment and $5.5 million from the Novel Biotherapeutics segment. R&D expenses for the second quarter of 2019 included $5.1 million from the Performance Enzymes segment and $2.9 million from the Novel Biotherapeutics segment.

Selling, general and administrative (SG&A) expenses for the second quarter of 2020 were $8.5 million, compared with $7.9 million for the second quarter of 2019, with the increase primarily due to costs associated with legal and accounting fees and outside services, and higher facilities and headcount, partially offset by lower allocable expenses. SG&A expenses for the second quarter of 2020 included $2.4 million from the Performance Enzymes segment, $0.6 million from the Novel Biotherapeutics segment and the remaining portion is included in $5.8 million in corporate overhead, depreciation, amortization and other expenses, net. SG&A expenses for the second quarter of 2019 included $2.4 million from the Performance Enzymes segment, $0.6 million from Novel Biotherapeutics and the remaining portion is included in $5.1 million in corporate overhead, depreciation, amortization and other expenses, net.

The net loss for the second quarter of 2020 was $6.3 million, or $0.11 per share, compared with a net loss for the second quarter of 2019 of $6.5 million, or $0.12 per share. Non-GAAP net loss for the second quarter of 2020 was $3.9 million, or $0.07 per share, compared with non-GAAP net loss for the second quarter of 2019 of $4.1 million, or $0.08 per share. A reconciliation of GAAP to non-GAAP measures is provided below.

Year-to-date Financial Results
Total revenues for the six months ended June 30, 2020 were $29.6 million, up 6% from $27.9 million for the six months ended June 30, 2019, and included $20.0 million in R&D revenue and $9.6 million in product revenue. R&D revenue for the first six months of 2020 included $8.8 million from the Performance Enzymes segment and $11.2 million from the Novel Biotherapeutics segment. R&D revenue for the first six months of 2019 included $6.4 million from the Performance Enzymes segment and $7.2 million from the Novel Biotherapeutics segment.

Gross margin on product sales for the first six months of 2019 was 56%, up from 50% for the prior-year period due to product mix.

R&D expenses for the first six months of 2020 were $21.8 million, compared with $16.3 million for the first six months of 2019, with the increase primarily due to higher regulatory expenses, higher headcount and higher allocable expenses, partially offset by lower lab supplies and outside services. R&D expenses for the first half of 2020 included $10.7 million from the Performance Enzymes segment and $10.4 million from the Novel Biotherapeutics segment. R&D expenses for first half of 2019 included $9.6 million from the Performance Enzymes segment and $6.2 million from the Novel Biotherapeutics segment.

SG&A expenses for the first six months of 2020 were $17.5 million, compared with $16.3 million for the first six months of 2019, with the increase due to an increase in costs associated with legal and accounting fees, higher facilities and headcount and licensed technology, partially offset by lower allocable expenses and lower travel expenses. SG&A expenses for the first half of 2020 included $4.7 million from Performance Enzymes, $1.2 million from the Novel Biotherapeutics segment and the remaining portion is included in the $12.0 million in corporate overhead, depreciation and amortization expense, net. SG&A expenses for the first half of 2019 included $4.5 million from the Performance Enzymes segment, $1.1 million from the Novel Biotherapeutics segment and the remaining portion is included in the $11.1 million in corporate overhead and depreciation and amortization expense, net.

The net loss for the six months ended June 30, 2020 was $14.0 million, or $0.24 per share, compared with a net loss for the six months ended June 30, 2019 of $11.6 million, or $0.21 per share. Non-GAAP net loss for the first six

months of 2020 was $9.0 million or $0.15 per share, compared with a non-GAAP net loss for the first six months of 2019 of $6.9 million, or $0.13 per share.

Cash and cash equivalents as of June 30, 2020 were $75.6 million, compared with $90.5 million as of December 31, 2019.

Non-GAAP Financial Measures
Consolidated financial information has been presented in accordance with GAAP as well as on a non-GAAP basis. On a non-GAAP basis, financial measures exclude the non-cash items depreciation expense and stock-based compensation expense. Non-GAAP financial measures presented are non-GAAP net income or loss, non-GAAP net income or loss per share (basic and diluted), non-GAAP R&D expense and non-GAAP SG&A expense. Non-GAAP operating expenses exclude stock-based compensation expense and depreciation of fixed assets.

Codexis management uses these non-GAAP financial measures to monitor and evaluate the Company’s operating results and trends on an ongoing basis, and internally for operating, budgeting and financial planning purposes. Codexis management believes the non-GAAP information is useful for investors by offering them the ability to identify trends in what management considers to be Codexis’ core operating results and to better understand how management evaluates the business. These non-GAAP measures have limitations, however, because they do not include all expenses that affect Codexis. These non-GAAP financial measures are not prepared in accordance with, and should not be considered in isolation of, or as an alternative to, measurements required by GAAP, and therefore these non-GAAP results should only be used for evaluation in conjunction with the corresponding GAAP measures. A description of the non-GAAP calculations and reconciliation to comparable GAAP financial measures is provided in the accompanying table entitled “Reconciliation of GAAP to Non-GAAP Financial Measures.”

Impact of COVID-19 Pandemic
We continue to experience some business disruptions as a result of the COVID-19 pandemic. Our headquarters in Redwood City, California are subject to local and state ordinances relating to sheltering in place for all non-essential businesses and activities. During the period from mid-March 2020 through the end of April 2020, in response to governmental orders governing the operation of businesses during the pandemic, we temporarily closed our Redwood City, California facilities which resulted in a suspension of research and development and pilot plant operations. In May 2020, we initiated limited operations and gradually ramped up our R&D operations so that at present we are utilizing the majority of our normal R&D capacity. Additionally, we resumed small scale manufacturing at our Redwood City pilot plant in May 2020. Our larger volume manufacturing partners have remained operational to date, enabling continued production of critical materials for our customers, and our supply chain team has continued to ship products near or on schedule. We and our partners continue to strive to meet customers’ product supply needs, but our forward deliveries may be impacted as the global situation continues to develop. In addition, restrictions on the ability to travel and access to our customers, partners, suppliers or contract manufacturers, as well as temporary closures of our facilities or the facilities of our customers, partners, suppliers or contract manufacturers could negatively impact our sales and operating results. The impact of the COVID-19 outbreak on local economies and the global stock markets could also lead to delays in delivering our products and services to customers and collaboration partners and decreased demand for our products and services. The total impact of these disruptions could have a material impact on our financial results. Due to the uncertain scope and duration of the pandemic, and uncertain timing of global recovery and economic normalization, we cannot at this time estimate the future impact on our operations and financial results. As a result, we have withdrawn our full year 2020 financial guidance.

These non-GAAP financial measures exclude the following items:
(a) Depreciation expense: We provide non-GAAP information which excludes depreciation expense related to the depreciation of property and equipment. We believe that eliminating this expense from our non-GAAP measures is useful to investors, because the acquisition of property and equipment, and the corresponding depreciation expense, can be inconsistent in amount and can vary from period to period.
(b) Stock-based compensation expense: We provide non-GAAP information which excludes expenses for stock-based compensation. We believe the exclusion of this item allows for financial results that are more indicative of our operations. We also believe that the exclusion of stock-based compensation expense provides for a better comparison of Codexis' operating results to prior periods as the calculations of stock-based compensation vary from period to period and company to company due to different valuation methodologies, subjective assumptions and the variety of award types.
