This is a preliminary prospectus supplement with all pricing terms left as blanks (TBD). The actual offering terms—size, coupon, maturity, and spread—will be set at pricing. Monitor the final 424B5 or pricing announcement for concrete terms; the debt issuance adds incremental leverage to an already highly capitalized utility, but within normal course for a regulated utility issuer. No earnings or guidance is provided, so no stock-moving catalyst here.

Executive Summary
National Grid plc files a preliminary 424B5 prospectus supplement for a U.S. dollar-denominated senior unsecured note offering of an undisclosed amount, with proceeds for general corporate purposes. Filing is a preliminary shelf takedown with terms TBD; no pricing, size, interest rate, or maturity date have been set. Given the preliminary nature, absence of any financial figures, and the routine capital markets transaction, this is a low-impact filing.
