Over the year to December 31, 2020, Theradiag recorded revenue of €10.4 million, up 8% compared with the €9.6 million in 2019, in line with the strategic plan drawn up by the Company.

The Theranostics business disclosed further strong growth of 15.5% in 2020, and this business now accounts for 49% of Theradiag's total revenue. Despite an unprecedented public health situation and the extension of plans blancs emergency plans in hospitals since mid-March 2020, this performance illustrates the solidity of this segment's business model.

In the United States, Theradiag notably achieved excellent performances reflecting the resounding success of its partnership with HalioDX. Sales ofTRACKER® range tests grew by 53% in this region compared with 2019. In France, where activity is now well established, sales on this segment grew by 4%. The Company's export business maintained a robust level of activity, with sales increasing by 15%.

IVD (in vitro diagnostics) activityrecorded a slight increase of 1.7% in revenue in 2020, to €5.3 million. It should be noted that the first half of 2019 included considerable non-recurring sales of instrumentation concluded with former partner HOB.

However, this base effect was offset by an opportunistic activity, Covid tests. Theradiag quickly took the initiative to mobilise its internal energies and resources to contribute to efforts to fight the pandemic. Sales related to the fight against Covid amounted to around €900 K in 2020, 95% of which were sales of antigenic tests.

On the IVD segment, as well as its core activity in autoimmunity incorporating quality controls and its screening and serology activities for fighting Covid, Theradiag is intending to accentuate its niche specialization strategy in areas such as genetics and male fertility.

Cash position

At December 31, 2020, Theradiag had net cash of €3.5 million, including a PGE state-guaranteed loan of €1.9 million, compared with €2.9 million at December 31, 2019 and €1.7 million at June 30, 2020.

Theradiag CEO Bertrand de Castelnau said:'Exceeding the symbolic and historic €10 million annual revenue level represents a remarkable performance achieved despite the unprecedented 2020 public health and economic context. This milestone is the result of the execution of our strategic orientations. Firstly, the restructuring of our business mix to focus more on Theranostics, which now accounts for half of the Company's sales. Secondly, the internationalization of our Company's activities through our partnership with HalioDX that has enabled us to post sales growth of 34% in the United States. In 2021, we intend to maintain this momentum in order to gradually improve our performance indicators'.

'Theradiag's 2020 growth performances within this hostile context emphasize our Company's sturdiness. I would particularly like to congratulate the Theradiag teams for their devotion and unwavering commitment. They represent key factors in our success', addedPierre Morgon, Chairman of Theradiag's Board of Directors.
