Goldman units log Attovia (NASDAQ: ATTO) 500K-share buy and equity swap trades
Rhea-AI Filing Summary
Attovia Therapeutics, Inc. (ATTO) reported insider activity by multiple Goldman Sachs–affiliated entities, all listed as former 10% owners. On August 6, 2026, they reported the conversion of Series B and Series C Preferred Stock into common stock, eliminating 18,181,830 Series B and 4,445,275 Series C preferred shares and issuing 1,957,134 and 478,598 common shares, respectively. This corrects an administrative error in an earlier Form 3 and reflects automatic conversion upon the IPO after a 1‑for‑9.29 reverse stock split.
On the same date, an affiliated entity purchased 500,000 common shares at $17.00 per share. On August 5, 2026, Goldman Sachs & Co.

The reporting persons disclaim beneficial ownership except to the extent of any pecuniary interest, and any Section 16(b) profit from the market‑making trades will be remitted to Attovia.

market maker financial
"were effected by Goldman Sachs & Co. LLC ("GS&Co") acting as a market maker in the ordinary"
A market maker is a firm or individual that stands ready to buy and sell a particular stock or other security throughout the trading day, posting prices at which it will transact so buyers and sellers can trade quickly. Think of it as a shopkeeper who keeps inventory and posts prices to ensure someone can always buy or sell; this reduces delays, narrows price swings, and helps investors execute trades at fairer, more predictable prices.
equity swap financial
"and establishment of long equity swap positions with respect to a total of 105,807 shares"
An equity swap is a private financial contract where two parties agree to exchange the gains and losses from a stock or stock index for the cash returns from another investment (like a loan rate or different asset). It lets an investor get the economic benefits or risks of owning a stock without actually holding the shares, similar to trading the fruit harvest from one orchard for the profits of another. Investors use equity swaps to gain exposure, manage risk, take temporary positions, or achieve tax or regulatory goals without buying or selling the underlying stock.
reverse stock split financial
"on a 1-for-1 basis, adjusted for a 1-for-9.29 reverse stock split effected by the Issuer"
A reverse stock split reduces a company's number of outstanding shares while raising the price per share proportionally, so the total value of each investor's holding is unchanged; a 1-for-10 split turns 100 shares worth $1 each into 10 shares worth $10 each. Companies often do this to regain compliance with an exchange's minimum price rule or to attract investors who avoid very low-priced stocks.
redeemable convertible preferred stock financial
"All shares of the Issuer's redeemable convertible preferred stock automatically converted into"
A redeemable convertible preferred stock is a special class of company shares that combines three features: it pays priority dividends like a safer, higher-ranking share; it can be converted into regular common shares so holders can join in upside; and it can be redeemed, meaning the company can buy it back for cash. For investors this matters because it offers a mix of downside protection and potential upside, but can change ownership stakes (dilution) and cash obligations depending on whether it’s converted or redeemed.
initial public offering financial
"reverse stock split effected by the Issuer on July 29, 2026, upon the completion of the Issuer's initial public offering"
An initial public offering (IPO) is when a private company first sells its shares to the public and becomes a stock-listed company. It matters because it allows the company to raise money from a wide range of investors, helping it grow, while giving early shareholders a way to sell some of their ownership.
pecuniary interest financial
"disclaims beneficial ownership of the securities reported herein except to the extent of its pecuniary interest"
