LumiraDx Reports First Quarter 2022 Results

Strong Growth in Instruments Delivered to Customers and Continued Innovation on our Platform

London, UK (May 11, 2022), LumiraDx Limited (Nasdaq: LMDX), a next-generation point of care (POC) diagnostics company, today announced financial and operational results for the first quarter ended March 31, 2022.

“We had a strong start to the year with increased revenues, instrument shipments and validation of our Platform by health systems and global health partners for an expanding menu of tests,” said Chairman and CEO Ron Zwanziger. “We are driving continued momentum and growth potential from our R&D pipeline with recent and planned product launches such as HbA1c, SARS-CoV-2 Ultra and our SARS-CoV-2 & Flu A/B combo and additional claims and markets for CRP and D-Dimer.”

“We have continued to innovate on our Platform with the Ultra test strip design, for which we plan to submit for CE mark shortly and which will deliver high sensitivity diagnostic test results in 5 minutes,” Zwanziger added. “We believe that the time saved will multiply testing throughput for health providers and improve care. Ultra has the potential to move the entire respiratory market to fast, high sensitivity testing.”

2022 First Quarter Financial Highlights

For the three months ended March 31, 2022, LumiraDx delivered revenue of $126.4 million compared to $106.9 million for the first quarter of 2021. SARS-CoV-2 Ag test strips on the LumiraDx Platform contributed $77.5 million and Fast Lab Solutions delivered revenue of $38.3 million. Our manufacturing investments enabled us to fully meet testing demand during the January surge of the COVID-19 pandemic and these investments position LumiraDx for rapid growth in volumes for both our existing products and our R&D pipeline of assays for more than 30 common health conditions.

Total gross margins for the first three months of 2022 were 40% compared to 41% for the same period last year. During the quarter the company delivered more than 4,000 instruments, primarily to U.S. customers, bringing the total to approximately 25,000 Platforms.

Research and development costs were $41.3 million in the first quarter of 2022.Our non-IFRS adjusted research and development costs, excluding amortization and share-based payment expenses, were $39.8 million in the first quarter of 2022, an increase of 53% over same period last year. The increase reflects our investments to open our new R&D center in Glasgow and increased spending to support the imminent launch of several new tests.

First quarter 2022 sales, marketing and administrative expenses were $40.2 million. Adjusted non-IFRS sales, marketing and administrative expenses, excluding amortization and share-based payment expenses, were $33.6 million in the first quarter of 2022, compared to $17.2 million in the first quarter of 2021. Adjusted operating loss for the first quarter of 2022 was $22.9 million. This compares to adjusted operating gain of $0.1 million for the first quarter of 2021.

Our net loss for the first quarter of 2022 was $55.7 million. Our non-IFRS adjusted net loss for the first quarter of 2022 was $32.1 million or $0.13 per fully diluted share compared to an adjusted net loss of $12.2 million or $0.09 per fully diluted share for the same period last year. Adjustments for our non-IFRS net loss in the first quarter of 2022 included a $19.2 million foreign exchange loss related mainly to the accounting for intercompany loan balances with no consolidated cash impact to the enterprise.

Our cash balance on March 31, 2022 was $166.0 million. In April, we entered a new financing agreement to provide working capital to fund additional instrument placements and announced the first closing of $26.1 million with a maximum of $50.0 million in aggregate investment which we anticipate completing before the end of the second quarter of 2022.

Cautionary Note Regarding Forward-Looking Statements

This press release contains forward-looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995, including statements regarding the effectiveness of our strategy, the timing of expected product launches, regulatory approvals, the advancement of our pipeline of tests, the benefits and performance of our tests, and the timing and availability of additional investments under our financing agreement. These statements involve risks, uncertainties and other factors that may cause actual results, levels of activity, performance or achievements to be materially different from the information expressed or implied by these forward-looking statements, including, among others, general economic, political and business conditions; the effect of COVID-19 on LumiraDx's business and financial results; obtaining or maintaining regulatory approval, authorization or clearance for our tests; and those factors discussed under the header "Risk Factors" in our Annual Report on Form 20-F for the year ended December 31, 2021, which was filed with the Securities and Exchange Commission, or SEC, on April 13, 2022 and other filings that we make with the SEC. Although LumiraDx believes that it has a reasonable basis for each forward-looking statement contained in this press release, LumiraDx cautions you that these statements are based on a combination of facts and factors currently known by it and its projections of the future, about which it cannot be certain. LumiraDx undertakes no obligation to update or revise the information

contained in this press release, whether as a result of new information, future events or circumstances or otherwise.

The securities offered in connection with the financing agreement described above have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or the securities laws of any state or other jurisdiction in the U.S, and may not be offered, pledged, sold, delivered or otherwise transferred, directly or indirectly, in the U.S. except pursuant to registration under the Securities Act or an applicable exemption from the registration requirements of the Securities Act and, in each case, in compliance with applicable other securities laws.

Non-IFRS Financial Measures

We present non-IFRS financial measures because we believe that they and other similar measures are widely used by certain investors, securities analysts and other interested parties as supplemental measures of performance and liquidity. We also use these measures internally to establish forecasts, budgets and operational goals to manage and monitor our business, as well as evaluate our underlying historical performance, as we believe that these non-IFRS financial measures depict the true performance of the business by encompassing only relevant and controllable events, enabling us to evaluate and plan more effectively for the future. The non-IFRS financial measures may not be comparable to other similarly titled measures of other companies and have limitations as analytical tools and should not be considered in isolation or as a substitute for analysis of our operating results as reported under IFRS as issued by the IASB. Non-IFRS financial measures and margins are not measurements of our performance, financial condition or liquidity under IFRS as issued by the IASB and should not be considered as alternatives to operating loss, gross margin or net income (loss) or any other performance measures, derived in accordance with IFRS as issued by the IASB or any other generally accepted accounting principles.

We define non-IFRS operating loss and non-IFRS net income (loss) as operating loss and net income (loss), respectively, excluding amortization, share-based payments, IFRS 2 listing expense, change in fair value of financial instruments, foreign exchange (gain)/loss, dividends on preferred shares and non-cash interest. We define non-IFRS expenses as expenses, excluding amortization and share-based payments. We recommend that you review the reconciliation of the non-IFRS measure to the most directly comparable IFRS financial measure provided in the financial statement tables included below, and that you not rely on any single financial measure to evaluate our business.
