Direct peers

• Pietro Fiorentini S.p.A. Italian manufacturer of gas pressure regulators, meters, and related equipment; Pietro Fiorentini's product portfolio (Aperval, Norval, Dival) is the technical backbone that Wohlgroth distributes in Switzerland under its Pietro Fiorentini AG Schweiz subsidiary, making them directly comparable in gas regulation technology.
• Hawle Armaturen AG: Swiss valve and fitting manufacturer for gas and water infrastructure; Wohlgroth is itself a subsidiary of Hawle, and the two operate as adjacent offerings in the same Swiss gas/water utility procurement channel, making Hawle a closely aligned peer on infrastructure components and DRM construction.
• RMG by Baker Hughes (Romet/Messtechnik): Manufacturer of gas meters, volume correctors, and flow computers used by gas utilities; product portfolio (turbine, rotary, ultrasonic meters) overlaps directly with Wohlgroth's gas measurement category and competes for the same utility customers across Europe.
• Schuck Group (Franz Schuck GmbH): German manufacturer of valves, fittings, and components for gas distribution — Wohlgroth resells Schuck's KKS/cathodic-corrosion-protection products; product portfolio and end-customers overlap meaningfully with Wohlgroth's pipeline-components business.

Broad incumbents

• Itron (Actaris / Gas measurement): Global leader in smart gas metering, AMI/AMR systems, and Cyble communication modules (which Wohlgroth resells); Itron is the upstream technology provider for much of Wohlgroth's smart-metering offering and a comparable broader incumbent in the same end-market.
• Honeywell Elster (Honeywell Process Solutions): Global gas metering and measurement solutions provider (formerly Elster Group) competing for utility AMI rollouts; directly comparable to Wohlgroth in commercial/industrial gas meters and volume correctors, but at much larger scale and global reach.
• Dresser Utility Solutions (天然气 / nat. gas): Supplier of gas meters, regulators, and pressure control equipment to gas distribution utilities; broadly comparable to Wohlgroth's combined pressure-regulation and metering offering, though at much larger global scale.
• Landis+Gyr: Global smart metering and grid infrastructure provider (electricity, gas, water); comparable as an AMI/AMI-rollout supplier to Swiss utilities and an adjacent competitor for gas and water smart-meter modernization programs.

Emerging players

• Ista Schweiz GmbH (heat/cost allocation metering): Provider of heat and water submetering solutions in Switzerland; overlaps with Wohlgroth's heat meter product line and addresses the same Swiss multi-utility building-services customer base from a service-led angle.

Regional players

• Stadtwerke-Komponenten / Seitz Vertrieb (regional Swiss gas infrastructure distributors): Smaller regional distributors and engineering firms serving Swiss gas utilities with comparable product/service bundles (pressure regulation, meters, station construction); Wohlgroth competes with these players for the same regional municipal and utility contracts.
