About these balances
Latest available filing per company, not a reconstructed current portfolio. Matching sequences show the last reported balance with all source rows expandable; grouping alone does not establish account ownership. Do not add unresolved positions together. Filings may omit unchanged positions, and amendments may correct only part of an older disclosure. Jointly reported shares are not necessarily this owner's personal holdings.

The amount of securities beneficially owned by the Reporting Person was incorrectly reported as 11,124 shares of common stock, which mistakenly included 8,360 shares of common stock. F1 · price: On February 11, 2015, Dawson Operating Company, previously known as Dawson Geophysical Company (the "Predecessor"), merged into a subsidiary of Dawson Geophysical Company, previously known as TGC Industries, Inc. (the "Issuer") (the "Merger"). In connection with the Merger, each share of the Predecessor's common stock, par value $0.33 1/3 per share, was converted into the right to receive 1.760 shares of the Issuer's common stock, par value $0.01 per share, after giving effect to a 1-for-3 reverse stock split of the Issuer's common stock, which occurred immediately prior to the Merger. On the effective date of the Merger, the closing price of the Predecessor's common stock was $10.23, and the closing price of the Issuer's common stock was $1.95, before giving effect to the 1-for-3 reverse stock split of the Issuer's common stock.
