Anson Funds Management filed a Schedule 13D disclosing a 5.7% position in SPS Commerce, the Minneapolis-based supply chain collaboration software provider with a $2.84 billion market capitalization. The filing arrived without advance notice on a Monday, and shares moved 4.2% intraday before settling at $158.33 by close. Anson, which runs $3.1 billion across long-short and credit strategies, typically engages boards directly within 30 days of disclosure.

SPS Commerce operates an EDI and supply chain visibility platform serving 120,000 retail and logistics customers, generating $561 million in trailing twelve-month revenue at 74% gross margins. The company has posted 31 consecutive quarters of revenue growth, but operating margins compressed 220 basis points year-over-year to 16.8% as integration costs from the OrderDynamics acquisition and elevated R&D spending outpaced revenue acceleration. The stock trades at 6.1x forward revenue, a 28% discount to vertical SaaS comparables like Descartes and E2open, despite holding $287 million in net cash and generating $142 million in free cash flow annually.

Anson's entry follows a pattern. The firm pursued strategic reviews at three other vertical software operators since 2021, twice pushing for sales processes that resulted in takeouts at premiums between 34% and 41%. SPS Commerce presents a clean balance sheet, recurring revenue concentration above 96%, and a customer retention rate of 98%, characteristics that attract financial sponsors and strategic acquirers. Private equity firms including Thoma Bravo and Vista Equity have acquired six supply chain software assets in the past eighteen months, paying median multiples of 8.2x forward revenue for platforms with comparable margin profiles. The discount here reflects concerns about customer concentration—the top 25 clients represent 18% of revenue—and elongated sales cycles in retail verticals adjusting to post-pandemic inventory normalization.

The operational lever is margin expansion. SPS Commerce runs a 1,247-person workforce with sales and marketing expense at 41% of revenue, above the 36% median for vertical SaaS peers with equivalent scale. The OrderDynamics integration, completed in Q2, added $18 million in annualized revenue but required re-platforming costs that management guided would normalize by Q4 2024. If Anson advocates for headcount rationalization in duplicated go-to-market functions and shifts R&D spend toward automation, the company could approach 22% operating margins within eight quarters without sacrificing growth, according to three sell-side models published in the past six weeks. That margin profile would justify a 7.8x to 8.4x revenue multiple, implying $195 to $210 per share before any takeout premium.

Allocators should watch for three developments. First, Anson will likely request board seats or file supplemental disclosures detailing operational recommendations within 21 days, based on the firm's prior campaign timelines. Second, SPS Commerce reports Q3 earnings on October 26, and management commentary on margin trajectory and M&A pipeline will indicate receptiveness to external pressure. Third, if Thoma Bravo or Vista initiate diligence, confidentiality agreements typically surface in amended 13D filings within 45 to 60 days of initial activist disclosure. The supply chain software consolidation cycle has another 18 months of momentum, and SPS Commerce sits in the valuation range where sponsors can model acceptable returns even at $210 entry prices.

Anson now holds 1.02 million shares across direct and derivative positions, with the firm's managing partners having participated in nine successful campaigns targeting vertical software operators since 2019. The EDI market remains fragmented, and SPS Commerce controls the largest share of SMB retail connectivity, a moat that persists regardless of activist involvement.
