Key Data Points
What this transaction means for investors
Lisanti Capital Growth focuses on small-cap growth stocks tied to major secular trends. Exiting Alphatec entirely during Q1 suggests the spine surgery technology company no longer aligned with their growth thesis.
Alphatec makes spinal surgery implants and an imaging system called EOS. The company just reported Q1 results that missed expectations. The stock is down more than 60% year to date and trades around $8, well below its $23 high from last year. Alphatec’s core surgical business is growing, with the number of cases and new surgeons up. But the EOS imaging division underperformed. Management cut full-year revenue guidance while maintaining profitability targets.
For investors in medical device growth stories, Lisanti's exit highlights a common tension: strong procedural adoption doesn't always translate to stock performance if one segment drags or if the market questions whether growth can sustain margins. Even solid surgeon adoption won't support valuations if capital-intensive product lines keep missing targets.
