Form 144 is a filing under U.S. securities regulations that companies and/or affiliates use to report plans for the resale of restricted or control securities. The Investing.com listings indicate separate Form 144 filings for each company on the same date, reflecting compliance with disclosure requirements tied to potential future sales by insiders or affiliates. The provided source text does not include additional details such as the number of shares, the identities of the filing persons, brokers, or whether any sales occur immediately. Instead, it identifies the filings by company and the date, consistent with routine regulatory reporting. Based on the available information, both companies submit their respective Form 144 forms on 15 June, and the filings are treated as administrative disclosures related to potential resale activity rather than operational updates.
