Welcome to our dedicated page for Aptevo Therapeutics SEC filings (Ticker: APVO), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
Aptevo Therapeutics Inc. filings document the regulatory record of a clinical-stage biotechnology company developing immune-oncology candidates based on ADAPTIR and ADAPTIR-FLEX platforms. Its 8-K reports record clinical updates for mipletamig in acute myeloid leukemia, annual financial results, material agreements, executive and board changes, and other public-company events.
The company’s proxy and registration filings disclose shareholder voting matters, proposed charter and administrative amendments, Nasdaq share-issuance approvals, common-stock financing arrangements, and capital-structure information related to its standby equity purchase agreement. These filings also provide formal context for governance, securities issuance mechanics, and the funding disclosures associated with Aptevo’s oncology pipeline.
Aptevo Therapeutics is registering up to 7,075,471 shares of common stock for resale by YA II PN, Ltd. under a standby equity purchase agreement. These shares will be issued to YA over time as Aptevo sells stock to it under a $60.0 million commitment, with purchase prices set at 96% of the lowest of three daily volume-weighted average prices in each pricing period. Aptevo will not receive proceeds from YA’s resale of the registered shares, but may raise capital from its direct sales to YA during a commitment period running to January 8, 2029, subject to ownership and exchange caps. As of September 30, 2025, Aptevo had 767,164 shares outstanding, so full issuance of all 7,075,471 shares reserved for this facility would represent a very large potential increase in its share count.
Aptevo Therapeutics is asking stockholders to approve three items at a virtual special meeting on February 18, 2026. The first would adopt an amended and restated certificate of incorporation that consolidates prior amendments, updates the company’s address, confirms perpetual duration, clarifies certain Delaware law voting provisions, and formally includes the designation of Series A Junior Participating Preferred Stock. The second seeks approval, under Nasdaq rules, for the potential issuance of 19.99% or more of the company’s common stock outstanding as of January 8, 2026 under a $60.0 million Standby Equity Purchase Agreement with Yorkville, which allows Aptevo to draw capital over 36 months at a discount to market VWAP. The third proposal would allow the meeting to be adjourned to solicit additional proxies if there are not enough votes for Proposals 1 or 2. There were 997,830 shares of common stock outstanding and entitled to vote as of January 9, 2026.
Aptevo Therapeutics Inc. has called a virtual special stockholder meeting on February 18, 2026 to vote on three proposals. The first would adopt an amended and restated certificate of incorporation that consolidates prior amendments, updates the company’s addresses, clarifies certain Delaware law voting mechanics, restates multiple past reverse stock splits, and formally includes the designation of Series A Junior Participating Preferred Stock, largely as technical and administrative changes.
The second proposal seeks approval under Nasdaq rules for the potential issuance of 19.99% or more of Aptevo’s common stock as of January 8, 2026 pursuant to a Standby Equity Purchase Agreement with Yorkville, which allows Aptevo to sell up to $60.0 million of common stock over 36 months, at 96% of the lowest volume-weighted average price over a three-day period for each draw. As of the January 9, 2026 record date, Aptevo had 997,830 shares of common stock outstanding, and a 19.99% cap currently limits issuances below a minimum price of $8.753 per share to 199,466 shares absent stockholder approval. The company states this facility is intended to provide flexible capital for working capital, operating expenses and business development, and warns that failure to approve the share issuance could impair funding and force it to seek potentially more dilutive alternatives.
The third proposal would allow adjournment of the meeting, if necessary, to solicit more proxies in favor of the charter amendment and SEPA share issuance. The board recommends that stockholders vote “FOR” all three proposals.
Aptevo Therapeutics Inc. entered into a $60.0 million Standby Equity Purchase Agreement with Yorkville, giving Aptevo the right, but not the obligation, to sell common stock to Yorkville over a 36‑month period through individual advances. Shares for each advance would be priced at 96% of the lowest daily VWAP over a three‑trading‑day period after Aptevo delivers an advance notice, and Aptevo may set a minimum acceptable price.
The agreement includes a 2.00% commitment fee on the $60.0 million, payable in five quarterly installments, and a $25,000 structuring fee to Yorkville. Under Nasdaq rules, issuance is capped at 199,466 shares, representing 19.99% of shares outstanding as of signing, unless shareholder approval is obtained or pricing conditions are met, and Yorkville’s beneficial ownership is limited to 9.99% of Aptevo’s outstanding common stock. Yorkville’s purchase obligation depends on an SEC registration statement for the advance shares being filed and declared effective.
Aptevo Therapeutics Inc. is registering up to 6,903,755 shares of common stock for resale by YA II PN, LTD. under a standby equity purchase agreement. These shares relate to an up to $25.0 million equity line Aptevo entered into with YA on June 16, 2025, under which YA buys shares from Aptevo at 96% of the lowest three-day VWAP during each pricing period. Aptevo will not receive any proceeds from YA’s resale of these shares.
As of September 30, 2025, Aptevo had 13,808,966 shares outstanding, and if all registered shares are issued, total shares outstanding would rise to 20,712,721. The company has already raised approximately $15.0 million under a prior registration and expects to use any additional proceeds from future sales to YA for pipeline development, new programs, business development, and general corporate purposes. The structure may lead to substantial dilution and stock price volatility, and the filing details Nasdaq listing and going-concern related risks.
