01:00 PM EDT, 08/25/2025 (MT Newswires) -- OraSure Technologies ( OSUR ) was warned by healthcare investor Ron Zwanziger that he might pursue a more "adversarial path" after the medical devices company rejected his all-cash acquisition offer, Reuters reported Monday, citing a letter it has seen.

"If the Board is not willing to entertain a collaborative discourse, we will be left with no choice but to consider all alternatives available," Reuters reported, citing the letter.

Zwanziger highlighted OraSure's ( OSUR ) declining cash reserves and share price, adding that the company's $40 million share buyback program has also "failed" to prop up the stock, according to the report.

OraSure Technologies ( OSUR ) did not immediately respond to a request for comment from MT Newswires.
