Cluster: 2 buyers in 30 daysHeadquartered in France, France, Cellectis belongs to the Healthcare & Pharma sector and traces its origins to 1999. Filings by its managers are published through AMF. Over the twelve months to 18 October 2026, 19 filings were filed, from 10 insiders.
Open-market activity splits into 4 purchases totalling €212k and 8 sales totalling €2.1M; 3 insiders sit on the buying side and 4 insiders on the selling side. The totals do not cover 1 filing with an undisclosed amount. Unlike grants, an open-market purchase is paid for by the insider, at the market price. The buyers include 2 senior executives and 1 finance chief. Andre Choulika filed the largest sale, €1.3M, on 3 June 2026, which represents 0.40% of the company's market value.
For context, the typical company on the same exchange (median of 316 companies) published 6 filings over the same period, against 19 filings here. Our records for Cellectis go back to 2023, with 4 purchases and 8 sales on the open market in total.
Within a 30-day window, 1 purchase overlapped with buying by a second insider. Purchases made close together by different insiders form what is called a cluster. The last insider purchase was made public on 29 September 2026, 18 days ago. The median gap between a trade and its publication by AMF is 5 days. For comparison, MAR article 19 gives managers three business days to notify a trade. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning.
In the same sector, recent insider purchases at Cooper Companies, Inc. and Cytosorbents Corp also feature in our signals. This summary is built from AMF disclosures alone and does not predict where the share price will go.

Cellectis is a clinical-stage biotechnology company focused on gene editing and the development of innovative immunotherapies against cancer. Founded more than 25 years ago, the company built its scientific foundation around two proprietary technologies: TALEN®, its flagship gene-editing platform, and PulseAgile, its electroporation system. These technologies support the design of next-generation cell and gene therapies, with an emphasis on safety, efficacy, and manufacturing scalability.
At the core of Cellectis’ business is the development of off-the-shelf allogeneic product candidates, especially gene-edited CAR-T therapies designed to be ready to use for patients. The company is primarily targeting high unmet-need hematologic cancers, including B-cell acute lymphoblastic leukemia (B-ALL) and non-Hodgkin lymphoma. Its pipeline includes several UCART programs intended to offer a potentially more industrializable alternative to personalized autologous approaches.
From a market positioning perspective, Cellectis is one of the European pioneers in applying gene editing to oncology. Its long-standing expertise in TALEN® provides a differentiated capability in precise cell engineering, which is strategically valuable in a highly competitive sector dominated by major pharmaceutical and biotechnology players. The company develops programs both internally and through scientific and industrial partnerships, including collaborations with major healthcare groups, in order to accelerate research and share development risk.
Cellectis is headquartered in Paris and also maintains operations in New York and Raleigh, reflecting a transatlantic footprint that supports research, development, and investor relations. The company is listed on Euronext Growth under ALCLS and on Nasdaq under CLLS. Its latest public financial update in spring 2026 confirmed progress across multiple Phase 1 and Phase 2 clinical studies, as well as ongoing strategic collaborations, highlighting a long-term strategy centered on disruptive innovation and the value creation potential of its gene-editing platform.
