Activist investors disclosed stakes in five mid-cap operators during the March filing window, concentrating pressure on software infrastructure providers and a specialty chemicals operator trading below historical multiples. The coordinated timing suggests strategic positioning ahead of Q1 earnings season, when underperforming operators typically face the most board receptivity. Combined market capitalization of the five targets exceeds $8.1 billion, with activist stakes ranging from 4.9% to 9.2% of shares outstanding.
Ashland, the $4.2 billion specialty chemicals operator, drew the largest single position at $387 million. The activist filing cited persistent underperformance relative to peer multiples in adhesives and coatings, where margin compression has exceeded 220 basis points since 2023. GeneDX Holdings, the genetic testing provider trading at 0.8x trailing revenue, saw a 7.1% stake filed alongside language typical of board seat demands. Alkami Technology, Satellogic, and Dynatrace each received filings between 5.3% and 6.8% ownership, with specific critique of capital allocation in Dynatrace's observability platform division.
The pattern matters for three reasons. First, the filing cluster arrives as software multiples compress 18% year-over-year, creating the valuation dislocation activists prefer for operational activism rather than pure financial engineering. Second, all five operators share a specific vulnerability: underinvestment in sales infrastructure relative to product development spend, a metric activists have used successfully in prior campaigns at Splunk and New Relic. Third, the March timing positions activists to influence annual meeting agendas before proxy deadlines in April and May, when institutional voters finalize governance decisions.
The broader activist landscape shows 43 new 13D filings in March, up 31% from the prior-year period and the highest first-quarter total since 2021. Software and healthcare operators account for 62% of new filings, compared to 41% in 2024. This shift reflects activist recognition that post-pandemic cost structures remain bloated in companies that scaled headcount aggressively in 2021-2022 but failed to rightsizeoperating expense ratios when growth normalized. GeneDX, for instance, carries a sales-and-marketing expense ratio of 47% despite revenue growth decelerating to single digits.
Operators and allocators should monitor three developments. First, proxy filings for Ashland and Dynatrace are due by mid-April; language around board composition and capital return will signal management receptivity. Second, Alkami's earnings call on April 28 will address activist concerns about its customer acquisition cost trajectory, which has deteriorated 22% sequentially. Third, Satellogic's liquidity position becomes material in Q2, when the activist filing specifically referenced balance sheet optimization and potential asset monetization.
The five simultaneous filings represent $712 million in disclosed activist capital, but the real number likely exceeds $1.1 billion when accounting for derivatives and pre-filing accumulation not yet visible in public disclosures. That concentration in mid-cap software and specialty industrials, rather than megacap tech, suggests activists are rotating toward operators where $50-100 million positions can credibly influence board decisions without requiring coalition-building among passive institutional holders.
The takeaway
Five activist filings in March target software and chemicals operators with shared vulnerability: bloated cost structures from 2021 scaling that boards have not yet addressed.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
