SEC.gov | Request Rate Threshold Exceeded

U.S. Securities and Exchange Commission

You’ve Exceeded the SEC’s Traffic Limit

Your request rate has exceeded the SEC’s maximum allowable requests per second. Your access to SEC.gov will be limited for 10 minutes.

Current guidelines limit each user to a total of no more than 10 requests per second, regardless of the number of machines used to submit requests. To ensure that SEC.gov remains available to all users, we reserve the right to block IP addresses that submit excessive requests.

The block will be lifted automatically by waiting 10 minutes. Continuing to exceed the SEC’s maximum allowable request rate during the time-out period will extend the duration of the time-out period. To ensure fair access for all users, please reduce the rate of your requests and visit SEC.gov again after the 10 minute time-out period has passed.

Internet Security Policy

By using this site, you are agreeing to security monitoring and auditing. For security purposes, and to ensure that the public service remains available to users, this government computer system employs programs to monitor network traffic to identify unauthorized attempts to upload or change information or to otherwise cause damage, including attempts to deny service to users.

Unauthorized attempts to upload information and/or change information on any portion of this site are strictly prohibited and are subject to prosecution under the Computer Fraud and Abuse Act of 1986 and the National Information Infrastructure Protection Act of 1996 (see Title 18 U.S.C. §§ 1001 and 1030).

To ensure our website performs well for all users, the SEC monitors the frequency of requests for SEC.gov content to ensure automated searches do not impact the ability of others to access SEC.gov content. We reserve the right to block IP addresses that submit excessive requests. Current guidelines limit users to a total of no more than 10 requests per second, regardless of the number of machines used to submit requests.

If a user or application submits more than 10 requests per second, further requests from the IP address(es) may be limited for a brief period. Once the rate of requests has dropped below the threshold for 10 minutes, the user may resume accessing content on SEC.gov. This SEC practice is designed to limit excessive automated searches on SEC.gov and is not intended or expected to impact individuals browsing the SEC.gov website.

Note that this policy may change as the SEC manages SEC.gov to ensure that the website performs efficiently and remains available to all users.

Item 1.01. Entry into a Material Definitive Agreement Subscription Agreement On March 9, 2026, Korro Bio, Inc., or Korro, entered into a subscription agreement with a number of institutional accredited investors pursuant to which it agreed to sell and issue in a private placement pursuant to the exemption in Section 4(a)(2) of the Securities Act of 1933, as amended, or the 1933 Act: (i) an aggregate of 4,501,928 shares of its common stock, par value $0.001 per share at a purchase price of $11.11 per share and (ii) pre-funded warrants to acquire an aggregate of 3,148,836 shares of its common stock at a purchase price of $11.109 per pre-funded warrant. The private placement was led by Venrock Healthcare Capital Partners, with participation from new and existing investors, including ADAR1 Capital Management, Affinity Asset Advisors, Balyasny Asset Management, Driehaus Capital Management, Kalehua Capital, Lynx1 Capital Management, Nantahala Capital, and New Enterprise Associates. The pre-funded warrants have an exercise price of $0.001 per underlying share of common stock, are immediately exercisable and have no expiration date. The number of shares of Korro common stock issuable upon exercise of each pre-funded warrant is subject to adjustment upon certain corporate events, including certain stock dividends and splits, combinations, reclassifications, and certain other events. The pre-funded warrants include a beneficial ownership blocker that provides that the holder may not exercise (nor may Korro allow the exercise) if upon giving effect to such exercise, it would cause the aggregate number of shares of Korro common stock beneficially owned by the holder (together with affiliates and any other persons whose beneficial ownership of our common stock would be aggregated for the purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended) to exceed 9.99% of the total number of then issued and outstanding shares of Korro’s common stock as determined in accordance with the terms of the pre-funded warrant. This threshold may be increased or decreased upon 61 days’ prior notice at the discretion of the holder, but not in excess of 19.99%. Korro expects the private placement to close on March 10, 2026, subject to customary closing conditions, and receipt of gross proceeds of approximately $85.0 million in cash, before deducting placement agent commissions and other offering expenses. Korro expects that the net proceeds from the private placement along with its existing cash and equivalents of $85.2 million as of December 31, 2025, will provide runway into the second half of 2028 and advance its pipeline of potentially transformational therapies for genetic diseases being discovered by OPERA®, Korro’s novel RNA editing platform, with the remainder used for working capital and general corporate purposes. Citigroup along with Cantor, Oppenheimer & Co., and William Blair are acting as placement agents for the private placement. The subscription agreeme
