Industry Context

StockSavvy.ai notes that the use of an at-the-market (ATM) offering program is a common and flexible method for biotechnology and other growth-oriented companies to raise capital without the immediate need for a large, underwritten offering. This filing suggests Scholar Rock is maintaining this flexibility.

Stakeholder Impact

• Existing shareholders may experience dilution if shares are sold under the ATM program.
• Investors considering purchasing shares will be subject to the terms outlined in the prospectus supplement and base prospectus.

Next Steps

• The company may offer and sell shares of its common stock from time to time through Jefferies as sales agent.
• The offering will be made only by means of the Prospectus Supplement and the base prospectus.
