Insights

Financial Analyst

TL;DR: PIMCO discloses a sizable, non-controlling 9.9% stake via direct shares and warrant-derived holdings.

PIMCO reports beneficial ownership of 2,690,808 shares, equal to 9.9% of the outstanding common stock, giving it sole voting and dispositive authority over these shares. The position combines 1,393,184 direct shares with 1,297,624 warrant-derived shares currently treated as beneficially owned because of a contractual 9.9% exercise limit on 2,517,517 warrant shares. This filing is a material ownership disclosure but does not, on its face, indicate control actions or activist intent; it documents a significant passive economic exposure held in advisory accounts.

Corporate Governance Expert

TL;DR: Ownership is material but capped; PIMCO records sole authority over reported shares while disclaiming broader beneficial ownership.

The Schedule 13G shows PIMCO has sole voting and dispositive power over 2,690,808 shares (9.9% of the class). The disclosure notes warrant-related limits that cap exercise to avoid exceeding 9.9%, and PIMCO disclaims beneficial ownership beyond its pecuniary interest since the securities are held for client accounts. From a governance perspective, the filing signals a significant shareholder position with voting authority but also highlights structural constraints on increasing that position via warrant exercise.

Item 4.	Ownership
(a)	Amount beneficially owned: 2,690,808 Based on (i) 1,393,184 shares of Common Stock and (ii) subject to the 9.9% Limitation (as defined below), 2,517,517 shares of Common Stock underlying certain warrants. The applicable warrants are subject to terms that limit exercise, if, after such exercise, the holder and its affiliates and any member of a Section 13(d) group with such holder and its affiliates would beneficially own more than 9.9% of the number of shares of Common Stock outstanding immediately after exercise (the "9.9% Limitation"). As a result of the limitation in the previous sentence, only 1,297,624 shares of Common Stock that such stockholders may acquire upon exercise of such warrants are currently beneficially owned by the Reporting Person. The securities reported in this Schedule 13G are held by investment advisory clients or discretionary accounts of which PIMCO is the investment adviser. When an investment management contract (including a sub-advisory agreement) delegates to PIMCO investment discretion or voting power over the securities held in the investment advisory accounts that are subject to that agreement, PIMCO considers the agreement to grant it sole investment discretion or voting authority, as the case may be, unless the agreement specifies otherwise. Accordingly, PIMCO reports on Schedule 13G that it has sole investment discretion and voting authority over the securities covered by any such investment management agreement and may be deemed to beneficially own the securities held by its clients or accounts within the meaning of Rule 13d-3 under the Securities Exchange Act of 1934. In accordance with SEC Release No. 34-39538 (January 12, 1998), this Schedule 13G reports the securities beneficially owned or deemed to be beneficially owned by PIMCO. It does not include securities, if any, beneficially owned by PIMCO's affiliates, whose ownership of securities is disaggregated from that of PIMCO in accordance with that release. PIMCO also disclaims beneficial ownership of these securities except to the extent of its pecuniary interest therein.
(b)	Percent of class: 9.9% Based on 25,882,259 shares of Common Stock outstanding as of August 4, 2025, as reported in the Issuer's Quarterly Report on Form 10-Q for the quarter period ended June 30, 2025, filed with the Securities and Exchange Commission on August 11, 2025.
(c)	Number of shares as to which the person has:
	(i) Sole power to vote or to direct the vote: 2,690,808
