Weekly Disclosures: AMR and CBLL Insider Buys

August 24, 2026 · Radar Report

Weekly Disclosures: Courtis’s 15,000-Share AMR Buy Reported Across Six Rows; CBLL CFO Buys $257K — Aug. 15–21, 2026

Notable trade disclosures for the week of August 15 through August 21, 2026, were concentrated in two tickers: AMR and CBLL. The supplied Form 4-derived dataset contains seven corporate insider purchases, including six AMR buys by director Kenneth S. Courtis and one CBLL buy by Chief Financial Officer Scott Blumberg. A data-retrieval date was not provided.

The standout is not six independent AMR signals but one director’s concentrated, same-day acquisition of 15,000 shares for about $2.90 million. Because all six AMR rows occurred on August 20, they are best treated as one same-day signal unless the underlying Form 4 shows otherwise.

This edition contains only corporate-insider filings; none of the notable transactions supplied for this period identifies a member of Congress.

Notable disclosed trades this week

Six AMR purchases by Kenneth S. Courtis

Together, the disclosed AMR transactions cover 15,000 shares and approximately $2,902,552 in listed purchase amounts. The individual purchases ranged from 333 shares at $189.84, for approximately $63,217, to 5,976 shares at $193.68, for approximately $1,157,432.

Across the six lots, Courtis paid a weighted average of approximately $193.50 per share.

CBLL purchase by Scott Blumberg

The week’s other notable entry was a CBLL purchase by Scott Blumberg, identified as the company’s Chief Financial Officer. Blumberg bought 27,333 shares at $9.41 on August 19, 2026. The listed amount was approximately $257,204.

The AMR transaction group was about 11.3 times the dollar value of the CBLL purchase. The AMR activity is the stronger dollar signal, but conviction cannot be assessed without post-transaction holdings and ownership type.

Methodology note

The supplied information does not include Form 4 links, accession numbers, filing timestamps, transaction codes, direct or indirect ownership status, reported post-transaction holdings, or a data-retrieval date, so those details and percentage increases in each insider’s stake cannot be provided without adding facts not present in the source material.

Disclosure timing matters

Weekly disclosure lists should be read with the timing distinction in mind. A trade date identifies when a transaction occurred, while the week refers to when it appeared among the notable disclosed trades being reviewed. Disclosures may become public after the underlying transaction, so they should not be treated as real-time records of trading activity.

For this week’s entries, the listed trade dates were August 19 and August 20, 2026. No filing dates or specific disclosure delays were provided, so the exact lag between each purchase and its public availability cannot be determined from the supplied information.

Congressional disclosures can lag trades by up to 45 days; Form 4 filings are generally due within two business days.
