On March 19, 2026, the SEC staff issued a new Compliance and Disclosure Interpretation (Question 116.26) addressing how Form S-3 eligibility may impact an existing at-the-market (ATM) offering. The interpretation considers a situation where a company establishes an ATM offering while it qualifies under General Instruction I.B.1, which allows companies with at least $75 million in public float to use Form S-3 without a cap on how much they can sell, but the company’s public float subsequently falls below that threshold when the required refresh of the registration statement occurs.
The staff determined that the company is not required to reduce the size of the ATM offering to comply with General Instruction I.B.6, which imposes a one-third cap on primary offerings by smaller reporting companies. Instead, the company may continue to sell the full amount of securities covered by the prospectus supplement that was filed before the required disclosure update even though that amount would exceed the limits that would apply if the ATM offering were being newly established after the change in eligibility.
The new interpretation effectively locks in the size of an ATM program as of the time the prospectus supplement is filed provided the company was eligible under General Instruction I.B.1 at that time. A later decline in public float does not require the company to reduce or re-size the existing program. However, the staff’s position does not permit an increase in the size of the ATM offering without regard to current eligibility limits and companies must continue to satisfy their ongoing disclosure obligations when they file their required disclosure updates.
