JUPITER, Fla., Nov. 12, 2024 — Dyadic International, Inc. (“Dyadic”, “we”, “us”, “our”, or the “Company”) (NASDAQ: DYAI), a biotechnology company focused on the efficient large-scale manufacture of proteins for use in human and animal vaccines and therapeutics, as well as non- pharmaceutical applications including food, non-food and industrial applications, today announced its financial results for the third quarter of 2024 and highlighted recent Company progress.

“We believe our third quarter achievements underscore Dyadic’s commitment to leveraging our proprietary Dapibus™ and C1 microbial protein production platforms to drive immediate and sustained revenue through the commercialization of alternative proteins for high value applications, while positioning the company for substantial mid- and long-term growth in human and animal health markets,” said Mark Emalfarb, Dyadic’s Chief Executive Officer. “This dual-track strategy is driving near-term milestones and licensing revenue, while our biopharmaceutical pipeline is providing significant upside potential. As we work to advance our efforts across all segments, Dyadic remains committed to delivering sustained value for our investors and partners.”

Dyadic’s Chief Operating Officer, Joe Hazelton, added, “Our collaborations in alternative proteins and biopharmaceuticals highlight the flexibility of our platforms, allowing us to deliver consistent results across diverse applications-from recombinant human serum albumin and alpha-lactalbumin to animal and human health vaccines and therapeutics. These advancements provide immediate and sustained revenue, with a potential for substantial value creation and expansion in the future.”

Recent Company Progress

Alternative Proteins

Non-Food Applications

• On June 28, 2024, the Company announced that it entered into a development and commercialization partnership with Proliant Health and Biologicals (“PHB”), a leading supplier of purified proteins for the diagnostic, nutrition and cell culture markets. Dyadic received an initial payment of $500,000 in July 2024, and a second payment of $500,000 for completing the transfer of a Production Strain in September 2024, and we expect to receive a final payment of $500,000 upon meeting a defined productivity threshold. Dyadic will also receive a share of profits received by PHB from the sale of animal-free recombinant albumin products produced using Dyadic’s platforms. A portion of the third payment will be allocated to the technology transfer and commercialization effort. The initial focus of the partnership is the commercialization of recombinant human serum albumin products, with the anticipated launch of the first product in the first half of 2025.
• The Company has completed its development of DNASE-1, and a Certificate of Analysis has been issued for the product. Sampling efforts are ongoing. The Company is currently in discussions with various manufacturing organizations to produce a research grade DNASE-1 product with anticipation of taking pre-orders in the first quarter of 2025.
• The Company has initiated development efforts to produce research grade DNA/RNA Polymerases, DNA Ligase, and RNase Inhibitor products. Cell lines have been developed with optimization and analysis ongoing. These enzymes are essential tools in molecular biology with unique functions in DNA and RNA manipulation.
• The Company continues to develop recombinant transferrin for use in cell culture media for the alternative protein industry and a Certificate of Analysis has been issued for the product. Product sampling occurred in the third quarter, earlier than originally estimated.
• The Company has made progress with its research grade recombinant bovine alpha-lactalbumin. A Certificate of Analysis has been issued for the product, and sampling is expected to begin in the late fourth quarter.

Food Applications

• During the third quarter, the Company has received its first milestone of over $400,000 for achieving the target yield from the development and exclusive license agreement entered into in 2023 to commercialize certain non-animal derived dairy enzymes used in the production of food products using Dapibus™. This is in addition to the upfront payment of $600,000 received in October 2023. The development of a second enzyme is progressing.
• The Company is sampling recombinant lactoferrin for several interested parties. The results of application testing for recombinant bovine transferrin for use in cell culture media for the cultured meat industry are expected in the fourth quarter.

Bio Industrial Products

• Development of five enzymes is ongoing with potential for use in multiple industries, such as nutrition, biogas, biofuels and biorefining. Sampling has been initiated with interested parties.

Animal Health

• The Company further expanded its collaboration with Phibro/Abic targeting vaccines for use in livestock animal diseases.
• The Company’s C1-produced H5 A/2.3.3.4.b A/Astrakhan ferritin nanoparticle antigen is being evaluated in poultry and cattle trials by multiple partners.

Human Health

• Co-developed a highly productive C1-produced ferritin nanoparticle Mpox (monkeypox) antigen with ViroVax LLC, achieving 4.5 g/L in 7 days. ViroVax is scheduled to begin preclinical studies for the Mpox vaccine beginning in Q4 2024.
• The Company is advancing its human health collaborations with partnerships with two top ten pharmaceutical companies and a leading biotech, having successfully expressed antigens for HIV, HPV, RSV, and other respiratory viruses.
• Third party collaborator(s) reported data demonstrating all three infectious disease monoclonal antibodies expressed from C1-cells showed similar neutralizing and binding activity when compared to monoclonal antibodies produced by Chinese Hamster Ovary (CHO) cells.
• The Company submitted multiple applications for grant funding from a leading Non-Governmental Organization in collaboration with Fondazione Biotecnopolo di Siena and other partners for a variety of vaccine antigens and antibodies.
• C1-produced H5 Clade 2.3.3.4.b A/Astrakhan recombinant ferritin nanoparticle sample provided to a prospective partner for development of potential H5 avian influenza ‘Bird Flu’ diagnostic kit.

Financial Highlights

Cash Position: As of September 30, 2024, cash, cash equivalents, and the carrying value of investment-grade securities, including accrued interest, were approximately $10.0 million compared to $7.3 million as of December 31, 2023.

Revenue: Revenue for the three months ended September 30, 2024, increased to approximately $1,958,000 compared to $397,000 for the same period one year ago. The increase is driven by the license revenue of $1.0 million from Proliant and a success fee of $425,000 from Inzyme.

Cost of Revenue: Cost of research and development revenue for the three months ended September 30, 2024, increased to approximately $396,000 compared to $106,000 for the same period a year ago. The increase in cost of research and development revenue was due to the increasing number of collaborations in 2024.

R&D Expenses: Research and development expenses for the three months ended September 30, 2024, decreased to approximately $460,000 compared to $716,000 for the same period a year ago. The decrease reflected the winding down of activities related to the Company’s Phase 1 clinical trial of DYAI-100 COVID-19 vaccine candidate as patient dosing was completed in February 2023 and a decrease in the amount of ongoing internal research projects.

G&A Expenses: General and administrative expenses for the three months ended September 30, 2024, increased by 1.2% to $1,298,000 compared to $1,282,000 for the same period a year ago. The increase reflected increases in business development and investor relations expenses of $52,000, and other increases of $24,000, offset by decreases in management incentives of $38,000, and accounting and legal expenses of $22,000.

Loss from Operations: Loss from operations for the three months ended September 30, 2024, decreased to $203,000 compared to $1,720,000 for the same period a year ago. The decrease in loss from operations was largely due to the license revenue of $1.0 million from the Proliant agreement and a success fee of $425,000 from the Inzyme agreement received in the third quarter of 2024.

Net Loss: Net loss for the three months ended September 30, 2024, was $203,000 compared to $1,614,000 for the same period a year ago.
