MRX (Nasdaq: MRX) seller plans 37,142-share sale after June trade

Rhea-AI Filing Summary

MRX filed a notice of proposed sales of restricted or control securities. The filing lists a planned sale of 37,142 shares of common stock through J.P. Morgan Securities LLC, with the stock listed on Nasdaq. It also reports that 37,143 shares of common stock were sold during the past three months. The reporting person is identified as Ian Lowitt, based in London.

Filing Explained

The July 13 notice covers a proposed 37,142-share filer sale, but does not show completion, price, or resulting ownership.

The July 13, 2026 Form 144 discloses a proposed resale of 37,142 common shares by Ian Lowitt; the filing does not establish that this proposed sale was completed, so it does not show a completed change in public ownership or company capital.

The shares were acquired from the issuer as compensation on May 19, 2025; J.P. Morgan Securities LLC is identified as broker and Nasdaq as the market. The filing does not state a sale price, trading plan, or post-sale holdings, so it does not quantify proceeds or the filer's remaining ownership.

The filing separately records 37,143 common shares sold by Ian Lowitt on June 12, 2026, without stating whether that earlier sale relates to the July 13 proposed sale.
