Direct peers

• SkyGeek: Online-first aviation parts and consumables distributor serving airlines, MROs, and FBOs globally. Operates a similar direct e-commerce model with bulk discounts, multi-brand catalog, and global shipping, overlapping directly with Silmid's commercial and general aviation segments.
• Wicks Aircraft Supply: Aviation parts and supplies distributor focused on certified aircraft components, consumables, and hardware for the GA and experimental aircraft market. Overlaps with Silmid on general aviation chemical consumables and accessories, though smaller and more GA-weighted.
• Aircraft Spruce & Specialty Co. Major US-based aviation supplies distributor serving general aviation, homebuilders, and commercial operators with a broad catalog including chemicals, hardware, and composites. Comparable in breadth of SKUs, e-commerce-led distribution model, and multi-vendor curation, though more GA-focused than Silmid.
• GracoRoberts: US-based parent of Silmid and the largest specialty chemicals distributor for aerospace in North America. Directly comparable product portfolio (adhesives, sealants, coatings) and customer base (OEM, MRO, defense) make it the closest peer for benchmarking operations and economics.
• Pilot John International: US distributor of aviation parts, consumables, and chemicals serving commercial, corporate, and general aviation. Comparable e-commerce distribution of lubricants, cleaners, and specialty fluids with similar value-added services, making it a relevant peer for cross-regional benchmarking.
• Consolidated Aircraft Supply: US distributor of aircraft parts, supplies, and consumables to airlines, MROs, and FBOs. Comparable product mix of lubricants, sealants, and adhesives with multi-vendor sourcing and value-added services.

Broad incumbents

• Brenntag: Global market leader in chemical distribution with multi-billion revenue scale across industrial, pharma, and specialty chemicals. Not aerospace-specialized but a useful benchmark for chemical distribution unit economics and an indirect competitor for some Silmid customers in adjacent verticals.
• Wesco International: Global industrial distribution leader offering MRO, aerospace, and specialty chemicals among broad product lines. Comparable as a scaled distribution platform with aerospace vertical exposure and similar value-added supply chain services.
• Univar Solutions: Major global chemical distributor with breadth across industrial and specialty chemicals including aerospace-adjacent product lines. Comparable as a large-scale chemical wholesaler serving industrial customers, though not focused on aerospace MRO.

Regional players

• Apex Industrial Supply: Industrial and aerospace MRO chemical distributor serving Latin America and Caribbean markets. Comparable product portfolio (lubricants, adhesives, cleaners) but operating in a different geographic corridor than Silmid, useful for understanding cross-regional aerospace distribution economics.
