Its total revenue for 2021 was approximately $4.3 million, up 2% from $4.2 million in 2020. “We are pleased with our fourth quarter and full-year 2021 financial picture as we look forward to our 2022 commercialization initiatives,” said Oliver Schacht, President & CEO of OpGen. “The Company’s positive 2022 outlook is based on OpGen’s improved cash position, existing network of partnerships, and recent collaborations.” “We are continuing to execute on our key development milestones, as recently seen with the successful completion of final verification and validation, as well as lifetime testing of the Unyvero A30 RQ platform,” Mr. Schacht continued. “I am pleased with our accomplishments and continue to believe we are putting our Company in a position to succeed.” Fourth Quarter and Full-Year 2021 Financial Results of OpGen, Inc. Total revenue for the fourth quarter of 2021 was approximately $1.43 million, compared with $1.35 million in the fourth quarter of 2020. Total revenue for the twelve months ended December 31, 2021 was approximately $4.3 million, compared to $4.2 million for the twelve months ended December 31, 2020.Operating expenses for the fourth quarter of 2021 were approximately $7.3 million, compared with $7.4 million in the fourth quarter of 2020. Total operating expenses for the twelve months ended December 31, 2021 were approximately $27.6 million, compared to $26.9 million for the twelve months ended December 31, 2020.The net loss available to common stockholders for the fourth quarter of 2021 was approximately $14.1 million, or $0.35 per share, compared with $7.1 million, or $0.34 per share, in the fourth quarter of 2020. The net loss available to common stockholders for the twelve months ended December 31, 2021, was approximately $42.0 million, or $1.14 per share, compared to $26.2 million, or $1.66 per share, for the twelve months ended December 31, 2020. The net loss available to common stockholders for the twelve months ended December 31, 2021, included non-cash charges of approximately $7.8 million and $7.2 million related to the Company’s 2021 warrant inducement and 2021 preferred stock offering, respectively. Cash and cash equivalents were approximately $36.1 million as of December 31, 2021, compared with $13.4 million as of December 31, 2020. In reporting OpGen’s Q4 2021 and full-year financials, Albert Weber, OpGen’s Chief Financial Officer (CFO), said, “As we have entered 2022, we see ourselves in a much better position than a year ago.” Mr. Weber joined OpGen in January 2022. “With existing products picking up sales and with the upcoming product commercialization pipeline, OpGen anticipates revenue growth to be significantly stronger in 2022 than the previous year and expects a steady improvement in gross margins over time. We expect our R&D, G&A and sales and marketing spend will be mostly on par with last year. We have a solid cash position to execute on our business plan.” “OpGen’s revenue growth is primarily attributed to the strong uptake in Unyvero sales in the U.S. and globally,” said Mr. Weber. “OpGen’s top line was further supported by significant increases in laboratory services, mainly due to COVID testing services performed by OpGen’s subsidiaries Curetis and Ares Genetics’ NGS-based services. Collaboration revenue declined mainly due to conclusion of a non-recurring R&D collaboration project at Ares Genetics and the New York State Department of Health project; however, it was more than offset by higher lab service revenue.” Mr. Weber reported that OpGen continues to explore restructuring options for the repayment of amounts due under its loan with the European Investment Bank, including through the payment of cash, possible amortization over time, issuance of equity over a period of up to 24 months or a combination of both. The Company is in discussion with the EIB as well as several other parties relating to such repayment options. The first tranche under the loan of approximately $15 million matures and is due in late April 2022 followed by maturity dates in June 2023 and June 2024 of approximately $4.4 million and $7.4 million, respectively. Such options would allow the Company to preserve cash and help avoid conversion of the debt to equity at this time when there are unfavorable market conditions. The Company believes that such changes will also provide greater flexibility and potentially help minimize dilution. The Company announced reaching the following key milestones, as well as recent developments in the fourth quarter and into 2022 to date: OpGen made two strategic hires as of January 1, 2022: Albert Weber joined OpGen as CFO and Managing Director of OpGen’s subsidiary Curetis GmbH, and Theo deVos joined as Senior Vice President of Corporate Development and Operations for Ares Genetics in the U.S.OpGen received FDA clearance for Acuitas AMR Gene Panel. Several commercial multi-year contracts have been submitted to hospitals and labs across the U.S. These remain subject to final negotiation. OpGen expects its first commercial sales of the Acuitas AMR Gene Panel in the upcoming quarter(s) of 2022.Enrollment for the Unyvero Urinary Tract Infection (UTI) Panel trial is progressing and the Company expects completing an interim data analysis and anticipates to communicate a relevant update early in the second quarter.OpGen closed a $15 million registered direct preferred stock offering with a single, U.S.-based, healthcare-focused institutional investor in October 2021. The investor subsequently converted all of its 150,000 shares of preferred stock into 7.5 million shares of common stock in December 2021, which resulted in total shares outstanding, as of December 31, 2021, of approximately 46.5 million shares of common stock with no preferred stock remaining outstanding.OpGen held a Special Meeting of Stockholders in December 2021, where both of its proposals were approved. The first proposal was to reduce the stockholder approval requirement to changes in the Charter to a majority of the outstanding shares entitled to vote. The second proposal was an amendment to the Charter to increase the authorized number of shares of common stock from 50 million to 100 million.The Ares database access deal in the fourth quarter 2021 contributed significantly to product revenue for the non-exclusive access to 1.1% of the ARESdb content to a leading global microbiology and In Vitro Diagnostics (IVD) corporation. Ares Genetics successfully completed the first part of a collaboration with a leading U.S. clinical research organization (CRO) and reference lab and has entered the next phase. During this next phase, Ares Genetics will gain access to up to 1,000 carefully selected proprietary genome and antibiotic susceptibility testing (AST) datasets. Ares Genetics aims to further increase the value of ARESdb and grow its contents in the future through strategic collaborations and clinical trials conducted by OpGen.OpGen completed successful verification and validation (V&V) testing, as well as lifetime testing, of its Unyvero A30RQ instruments. In outlining OpGen’s 2022 initiatives, Mr. Schacht said, “We look forward to achieving upcoming key milestones in the development and commercialization of our innovative diagnostic test portfolio.” “OpGen’s recent 510(k) approval for its Acuitas AMR Gene Panel, the commercial launch of the AREScloud web application, and Ares Genetics’ strategic non-exclusive database access transaction, have already set the tone for 2022,” Mr. Schacht said. “OpGen is expecting to report results of its Chinese clinical study once completed and pending clearance decision by the China’s National Medical Products Administration (NMPA), its Unyvero UTI clinical trial and anticipated FDA submission, the Unyvero A30 platform development and partnering activities, and Ares Genetics’ commercial expansion in Europe and the U.S.” In terms of guidance for 2022, OpGen expects to: grow its U.S. direct product sales of Unyvero and Acuitas by 50% or greater;continue to grow its European and international distribution business for Unyvero products albeit at more moderate growth rates;gain significant traction and acceleration in Ares Genetics related services and software solutions business;achieve overall revenue growth from the products and services business for 2022 in a range of approximately around 25% to 50% year over year; andhave significant upside potential from revenue recognition under any potential future strategic partnering or licensing deal for the Unyvero A30 platform or the Ares database assets.
