This disclosure provides market participants with advance warning of potential future public float supply.

Significance of Form 144 Filings

Form 144 is a mandatory U.S. SEC disclosure document for insiders and affiliates intending to sell securities, designed to advance notice of potential share selling rather than confirm that a sale has already been completed. Filing this form does not require prior SEC approval, but it requires accurate disclosure of the seller’s identity, number of proposed shares, valuation, and proposed sale timeline, allowing markets to pre-assess potential selling pressure risks.

Relevant Market Context

Per publicly available institutional holding data, as of December 31, 2025, OSCR had 371 institutional holders, accounting for 65.0% of its public float, a net decrease of 12 holders from the prior quarter. Of these, 64 institutions established new positions, 185 increased their holdings, 115 reduced their positions, and 69 fully exited their holdings. For analyst ratings, as of June 1, 2026, the distribution was 3 Strong Buy, 8 Hold, 1 Sell, and 1 Strong Sell, with the rating structure largely unchanged from May 1, 2026, except for a one-position increase in Strong Buy ratings.

What This Signal Does Not Prove

First, this disclosure only outlines a proposed sale plan and does not confirm that the shares will ultimately be sold. Second, this signal does not constitute any investment advice, nor can it directly infer the specific motivation for the proposed sale, which may only reflect the seller’s asset diversification or personal liquidity needs. Third, this filing provides no additional information about recent changes to the company’s fundamentals, so it cannot be directly linked to adjustments in the company’s operational or financial performance.
