Special Situations Digest #38

Jana Partners disclosed an activist stake in Casella Waste Systems (CWST) in October 2026 and presented its case at the 13D Monitor investor summit on October 20. Jana wants a roughly 27% EBITDA margin by 2029, outside performance consultants and pay tied to shareholder returns, after operating margins fell 5.2 points over five years; it also sees Casella as a possible M&A target given its valuation and northeastern U.S. footprint. The shares rose about 5% on the news.

Everrise Holdings LLC, Juno Cloud Technologies Limited, and Chunlin Chen now own 34.51% of ATA Creativity Global (AACG) and intend to influence the company's strategic direction, management, and operations (Schedule 13D). The group acquired 45.3 million shares for $21.1 million at $0.4667 per share in a transaction that closed on July 21, 2026. An Investor Rights Agreement provides registration demand rights exercisable six months after that closing date. The group currently has no plans for board or capitalization changes but may consider them in the future. This significant stake creates a control vector at a small-cap issuer with registration rights becoming exercisable.

Mattel, Inc. (MAT) entered into a cooperation agreement on October 21, 2026 with EdgePoint Investment Group Inc., which owns about 17.7% of the company: 50.5 million shares bought for $829.7 million, per its Schedule 13D (Form 8-K). Mattel appointed EdgePoint Partner Lee Matheson to the board effective October 21, expanding it to ten members, and will nominate him at the 2027 annual meeting. The agreement includes standstill and confidentiality provisions, and Mattel's obligations end if EdgePoint's ownership falls below 10%. It gives the largest holder a board seat without a proxy contest.

Winnebago Industries, Inc. (WGO) entered a cooperation agreement with Vision One on October 22, 2026, to resolve shareholder proposals and director nominations. The company will nominate Jay L. Johnson as an independent Class III director for the 2026 annual meeting and will submit charter and bylaw amendments to phase out the classified board over three years. Vision One irrevocably withdrew its September 15, 2026 notice of proposals and nominations and will cease all solicitation for the 2026 annual meeting. The agreement includes a standstill and terminates on the earlier of 30 days before the 2027 nomination deadline or 120 days before the one-year anniversary of the 2026 annual meeting. This settlement removes the threat of a contested slate at the 2026 annual meeting, leaving the shareholder vote on declassification amendments and the election of the agreed director as the primary actionable items.

Any change in payout or governance may affect how investors weigh the current valuation against forecast growth.

Reuters reported on October 20, 2026 that U.S. activist investor Ananym Capital had taken a stake in CTS Eventim (EVD.DE) and called the company significantly undervalued. Ananym pointed to clearer business disclosure, artificial intelligence applications and a possible share buyback as areas for value creation. The size of Ananym's stake has not been disclosed. CFO William Willms departed effective September 30, 2026, the third CFO departure since 2020. First-half 2026 revenue rose 17.0 percent to EUR 1.5 billion (~$1.7B); adjusted EBITDA rose 12.4 percent to EUR 225 million (~$252M), with margin down to 14.9 percent from 15.5 percent.

Two shareholders filed a provisional injunction application at Seoul Southern District Court to inspect and copy the accounting books and related documents of Copus Korea Co., Ltd. (322780.KQ). The applicants seek 20 business days of access at headquarters with a requested non-compliance payment of KRW 1.0 million per applicant per day (KRW 2.0 million per day in total). Copus Korea confirmed receipt of the court documents on 2026-10-23, and no court decision has been issued. This is an early legal escalation step by shareholders against the issuer, filed under a management-rights-dispute caption. The court's grant-or-deny decision is the next observable catalyst.

Meeka Metals Ltd (MEK.AX) disclosed Stephen Mayne’s self-nomination for its board in its October 23, 2026 AGM notice. Mayne cited concerns about inaccessible physical AGMs in Perth and institutional placements without a retail Share Purchase Plan. The board unanimously recommends voting against his election. Resolution 4 will put his nomination to shareholders at the November 24, 2026 AGM, creating an election contest focused on retail-shareholder treatment and governance.

The 11.82% stake and explicit proposal plan put the company in play for shareholder-driven change.

UGS Asset Management Co., Ltd. now owns 5.02% of Mitani Sangyo Co., Ltd. (8285.T) after acquiring 3.1 million shares for 1.9 billion yen (large shareholding report).

This filing signals activist intent through a stated goal of significant proposals and a plan to increase the stake.
