SCHLIEREN (ZURICH), SWITZERLAND / ACCESSWIRE / March 13, 2024 / Kuros Biosciences (“Kuros” or the “Company”), a leader in next-generation bone graft technologies, today announced financial results for full year 2023 along with continued significant growth.

Direct sales of MagnetOs rose 163% to CHF 31.7 million in 2023 from CHF 12.1 million in 2022. Total medical device sales accelerated from CHF 13.3 million in 2022 to CHF 33.6 million in 2023, which is a 153% increase. MagnetOs exceeded its commercial plan in 2023 by reaching the important milestone of 25,000 patients treated worldwide, resulting in a positive EBITDA of CHF 6.8 million in the Medical Devices product segment in 2023.

Chris Fair, Chief Executive Officer, stated: “Kuros Biosciences experienced a tremendous year in 2023 as we built a newly focused, scientifically led and clinically proven, pure play MedTech business. Last year’s record sales revenue, coupled with our global expansion efforts and a dedicated strategy, marked a successful period as we transitioned to becoming a global leader in bone grafting technologies. Our significant, 153% revenue growth of MagnetOs sales in 2023 compared to last year corresponds to the treatment of over 25,000 patients with MagnetOs.

Mr. Fair continued, “The marked growth in revenue for 2023 is a result of a well-executed plan of geographic and sales channel expansion led by our expert sales, marketing, and customer service teams. In addition, our continued investment in innovation, and operational excellence in manufacturing, quality, and logistics has ensured that we can meet and exceed our customers’ demands, ensuring that no patient will miss treatment. With our recent decision to focus our financial resources on the MagnetOs technology and associated portfolio of products, and not to proceed into Phase 3 with Fibrin-PTH, we have made significant progress toward reaching a cash flow break-even point more quickly. These strong financial results underline our commitment to increasing shareholder value by balancing high sales growth with targeted profitability.”

Group financial results

Revenue and cost of goods sold

In 2023, direct sales of MagnetOs rose by 163% from CHF 12.1 million to CHF 31.7 million in 2023. Total revenue from medical devices arrived at CHF 33.6 million (2022: CHF 13.3 million), showing an increase of 153% or 166% on a constant currency basis versus 2022. Cost of goods sold amounted to CHF 9.6 million (2022: CHF 7.2 million) of which CHF 1.8 million (2022: CHF 2.2 million) related to the amortization of capitalized R&D; and CHF 4.4 million and CHF 0.1 million related to impairment of goodwill and intangible assets respectively. (2022: impairment of goodwill of CHF 3.6 million).

Net operating costs

Operating costs amounted to CHF 37.1 million, compared to CHF 24.2 million in the previous year. The increase is primarily driven by sales and marketing costs resulting from growing commercial activities. Therefore, sales and marketing costs increased from CHF 12.8 million in 2022 to CHF 23.3 million in 2023, mainly due to the increase in sales force headcount and general sales and distribution costs. Research and development costs increased from CHF 5.2 million in 2022 to CHF 5.6 million in 2023. General and administrative costs increased from CHF 6.6 million in 2022 to CHF 8.4 million in 2023. Other income amounted to CHF 0.2 million (2022: CHF 0.4 million).

Net finance expense

Net finance expense amounted to CHF 0.2 million (2022: CHF 2.5 million), mainly comprised of a gain resulting from a revaluation on financial liability to XOMA because of the re-assessment of the probability assumption of future milestone payments, net of the result of foreign exchange.

Financial position and other assets

Cash and cash equivalents amounted to CHF 14.2 million and funds available (including trade and other receivables) totaled CHF 21.8 million as of December 31, 2023. This is a decrease of CHF 5.9 million from CHF 27.7 million as of December 31, 2022. The decrease is mainly driven by net operating cash outflows.

As of December 31, 2023, total intangible assets amounted to CHF 16.5 million (2022: CHF 19.4 million) and goodwill amounted to CHF 24.5 million (2022: CHF 29.3 million). The impairment of goodwill of CHF 4.4 million resulted from a reassessment of the assumptions underlying the expected milestones from Checkmate licensing.

About MagnetOs

MagnetOs is a bone graft like no other: thanks to its NeedleGripTM surface technology, it grows bone even in soft tissues. This surface technology provides traction for our body’s vitally important ‘pro-healing’ immune cells (M2 macrophages). This in turn, unlocks previously untapped potential to stimulate stem cells – and form new bone throughout the graft. The growing body of science behind NeedleGrip is called osteoimmunology. But for surgeons and their patients it means one thing: a more predictable fusion. 1-5*†‡
