5. Segment Information

Stevanato Group business operations are organized into two reportable segments, based on their specific products and services:

In 2022, Stevanato Group generated 81% of total sales from the Biopharmaceutical and Diagnostic Solutions segment (82% in 2021), and 19% from the Engineering segment (18% in 2021).

The Biopharmaceutical and Diagnostic Solutions Segment deals mainly with the design and production of glass containers and packaging solutions, based on sophisticated technical and industrial processes. The production of Drug Containment Solutions (DCS) accounts for more than 50% of total sales and represents the Group's core business. The glass manufacturing process multiplies complex and requires sophisticated industrial processes, to form, treat, inspect and package drug containment and delivery products. The critical phases of Stevanato Group's business model are managed internally while only the production of glass tubes (which serve as the starting point of the internal production process) and the sterilization process for the final products are outsourced to a trusted network of third parties’ suppliers. Drug Containment Solutions includes ampoules, vials, ready-to-fill containers, cartridges and pre-fillable syringes.

Within the same segment there is also the production of In-Vitro Diagnostic (IVD) Solutions and Drug Delivery Systems (DDS). This sector is particularly complex as it requires constant cooperation with each customer for the development of the specific products they need. The production of plastic products requires development of specific molds based on each customer's requirements and specifications, which molds are then used for stamping of the final product. The product portfolio is highly diversified and includes different products for pharmaceutical, medical and diagnostic industries.

Additionally, the Group has recently entered the drug delivery system business offering pen injectors, dry powder inhalers, auto-injectors and wearable injectors.

Stevanato Group also provides analytical services and regulatory support exclusively to its customers, as ancillary services to the supply of DCS. Stevanato Group's analytical testing facilities in Piombino Dese, Italy, and Boston, Massachusetts, focus on investigating the physiochemical properties of primary packaging materials and components and studying the interactions between drug containment solutions and the drugs they will contain. The Analytical Services provided include chemical analysis, surface characterization, container performance and interaction, testing on drug delivery systems and customized testing based on the specific need of each client.

The Engineering Segment designs, develops and produces equipment and machinery for both in-house use and the sale to customers (which includes some of Stevanato Group's competitors). Stevanato Group is driving continuous technological advancements so that its equipment can consistently meet the client's stringent specification requirements. The Group assembles equipment and machinery and develops the software necessary for its functioning beyond working closely with the customers to install the machinery and equipment in their production sites, ensuring they are correctly calibrated and properly functioning. Engineering products include glass converting machinery, visual inspection machinery, assembly platforms, secondary packaging machinery. The after-sales services, mainly consists in the provision of spare parts for our machinery and equipment other than maintenance activity on the machines sold.

The Group also provides professional project management services, supporting its customers in designing their plant layout for the production of bulk and ready-to-use pharmaceutical primary packaging.

Inter-segment revenue and costs are eliminated upon consolidation and reflected in the “adjustments, elimination and unallocated items” column. The most relevant adjustment in revenue relates to the sales of the Engineering’s equipment to the Biopharmaceutical and Diagnostic Solutions.
