Insights
Empery and Ryan Lane hold a capped minority stake (4.99%) including warrant exposure.
Reporting shows shared voting and dispositive power over 2,298,892 shares, with the ownership percentage calculated using 44,648,737 shares outstanding as of November 28, 2025. The filing explicitly notes a contractual Blocker that prevents exercise above 4.99%.
Key dependencies include the 1,421,247 warrants referenced and the blocker mechanics; future changes in outstanding shares or exercised warrants would alter percentage ownership. Subsequent filings will show any exercise or disposition activity.

Warrantsfinancial
"Common Stock issuable upon exercise of the Warrants (as defined in Item 2(a))"
Warrants are special documents that give you the right to buy a company's stock at a set price before a certain date. They are often used as a way for companies to attract investors or raise money, and their value can increase if the company's stock price goes up.
Beneficial ownershipregulatory
"may be deemed to be the beneficial owner of all of the shares of Common Stock"
Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.
Schedule 13G/Aregulatory
"This statement is filed by the entities and persons listed below"
A Schedule 13G/A is an amended public filing with the U.S. securities regulator that updates a previous Schedule 13G, disclosing when an individual or group holds a substantial (typically over 5%) stake in a company and is claiming a passive, non‑controlling intent. Investors monitor these updates because rising or falling holdings can signal changing confidence, potential future moves, or shifts in voting power — like watching a public ledger where large shareholders quietly adjust their positions.

Item 4.
Ownership
(a)
Amount beneficially owned:
The information required by Item 4(a) is set forth in Row 9 of the cover page for each of the Reporting Persons and is incorporated herein by reference.
The percentage set forth in this Schedule 13G is calculated based upon an aggregate of 44,648,737 shares of Common Stock outstanding as of November 28, 2025, as reported in the Company's Prospectus Supplement filed with the Securities and Exchange Commission pursuant to Rule 424(b)(5) on December 1, 2025, and assumes exercise of the Warrants (subject to the Blocker (as defined below)).
Pursuant to the terms of the Warrants, the Reporting Persons cannot exercise the Warrants to the extent the Reporting Persons would beneficially own, after any such exercise, more than 4.99% of the outstanding shares of Common Stock (the "Blocker"), and the shares of Common Stock listed as beneficially owned in Rows 6, 8 and 9 of the cover page for each Reporting Person and the percentage set forth in Row 11 of the cover page for each Reporting Person give effect to the Blockers. Consequently, as of the date of the event which requires the filing of this statement, the Reporting Persons were not able to exercise all of the Warrants due to the Blocker.
The Investment Manager, which serves as the investment manager to the Empery Funds, may be deemed to be the beneficial owner of all of the shares of Common Stock held by, and the Common Stock issuable upon exercise of the Warrants (subject to the Blocker) held by, the Empery Funds. The Reporting Individual, as the managing member of a limited liability company that is the managing member of the General Partner of the Investment Manager with the power to exercise investment discretion, may be deemed to be the beneficial owner of all of the shares of Common Stock held by, and the Common Stock issuable upon exercise of the Warrants (subject to the Blocker) held by, the Empery Funds. The foregoing should not be construed in and of itself as an admission by any Reporting Person as to beneficial ownership of the shares of Common Stock owned by another Reporting Person. Each of the Empery Funds and the Reporting Individual hereby disclaims any beneficial ownership of any such Common Stock.

What stake does Empery Asset Management report in IMPP?
Empery reports beneficial ownership of 2,298,892 shares, equal to 4.99% on a fully-exercised-warrants basis. This percentage uses 44,648,737 shares outstanding as of November 28, 2025 and is subject to an exercise Blocker.
How many warrant-derived shares are included in Empery and Lane's count?
The filing states 1,421,247 shares are issuable upon exercise of the Warrants and are included in the beneficial ownership calculation. Exercise is limited by a contractual Blocker preventing ownership above 4.99%.
What is the meaning of the 4.99% "Blocker" in the filing?
The Blocker prevents the Reporting Persons from exercising Warrants to acquire shares that would raise beneficial ownership above 4.99%. The cover-page percentages explicitly reflect the Blocker when calculating ownership percentages.
Does Ryan M. Lane personally hold the reported shares?
Ryan M. Lane is reported both personally and as related to Empery Funds; the filing states he may be deemed to have beneficial ownership through his role but also includes disclaimers from the Empery Funds and the Reporting Persons.
What outstanding share count did the filing use to compute percentages?
The ownership percentage is calculated using 44,648,737 shares outstanding as of November 28, 2025, cited from the Company’s Prospectus Supplement filed December 1, 2025, and tied to the warrants exercise assumption.
