Alphatec Holdings (ATEC) concentration risks

The company's disclosed concentration profile combines a high-share supplier dependency and a medium-share product exposure, both of which are meaningful but distinct in character. On the supply side, the company relies in one case on a single source vendor, Invibio, to provide the raw materials used in the production of its products, a high-share dependency by disclosed size. The character here is clearly dependency: sole-source raw materials have no ready substitution path, meaning any disruption at Invibio — whether quality, capacity, contractual, or operational in nature — could interrupt production across the company's product lines. This is the most idiosyncratic element of the profile and the exposure most likely to cause an abrupt operational impact. On the product side, net sales of systems that include polyaxial pedicle screws represented approximately 38% of net sales for the year ended December 31, 2025, a medium-share structural exposure. Polyaxial pedicle screw systems are a meaningful component of the revenue base, though not a majority, and the structural character reflects the company's deliberate positioning in the spine surgery market rather than a narrow product line that could vanish from the portfolio without warning. Taken together, the supply-side Invibio dependency is the more urgent watch item — a sole-source disruption would affect the entire product line rather than just the polyaxial screw segment. The product concentration adds a demand-side overlay, making the company's results sensitive to trends in spine surgery volumes and competitive dynamics in the pedicle screw category.
