Corvex Management LP

The portfolio's two largest positions frame the transition. Illumina Inc ($472.0M, 18.8%, 3.83M shares, essentially flat) — a life-sciences-and-genomic-sequencing company and Corvex's largest position — declined in value from $502.3M in Q4 to $472.0M in Q1, but the share count was UNCHANGED. This is a pure mark-to-market decline: the manager held the position through Illumina's stock-price drop. Illumina is Corvex's most well-known activist campaign — the fund has publicly pushed for governance-and-strategic changes at Illumina and has accumulated a large-and-stable position over multiple quarters. The fact that the share count held flat through a 6% stock-price decline signals continued activist conviction; reducing would have undercut the public campaign. GeneDx Holdings ($207.3M, 8.2%, 3.23M shares, +170,520 shares, +5.5%) — a genetic-testing-and-rare-disease-diagnostics company — declined in value from $397.8M in Q4 to $207.3M in Q1 despite the manager ADDING 170,520 shares. This is the most striking trade in the filing: the manager ACTIVELY BOUGHT into a stock that declined by ~48% in value, roughly doubling the share-add rate while the price collapsed. GeneDx is another Corvex activist target — the fund has pushed for board representation and strategic-review at GeneDx. The 5.5% share increase into massive price weakness signals a conviction that GeneDx's long-term earnings power justifies the current entry price, OR that the activist campaign is approaching a catalyst event.

The third and fourth largest positions reflect the portfolio's consumer-and-utilities anchor. Southwest Gas Holdings ($375.2M, 14.9%, 4.32M shares, -$27.3M, -14.2% shares from a 5.03M-share base) — a regulated natural-gas utility — was actively reduced; both share count and value declined. Southwest Gas had been a stable top-five position in prior quarters and its reduction signals an active exit from the gas-utility thesis. This may reflect Corvex's view that regulated-gas utilities face structural headwinds from electrification and decarbonization policy, or it may be a tactical raise of dry powder for the activist campaigns. Walt Disney Co ($208.2M, 8.3%, 2.16M shares, -$70M, -11.6% shares) — media-and-entertainment — was reduced but maintained as a top-five position. Disney is a Corvex position with an activist-conviction overlay; the fund has expressed views on Disney's streaming-and-capital-allocation strategy. The 11.6% share reduction in Q1 may be a trim rather than an exit. MGM Resorts International ($197.9M, 7.9%, 5.35M shares, essentially flat) — hospitality-and-gaming — was held steady. Amazon.com ($183.8M, 7.3%, 882,732 shares, -$43M, -10.2% shares) — e-commerce-and-cloud — was reduced. Restaurant Brands International ($116.6M, 4.6%, 1.58M shares, -$48M, -34.5% shares) — quick-service-restaurants — was significantly reduced; the share count fell from 2.41M to 1.58M. The Restaurant Brands reduction and the Disney reduction together suggest Corvex is trimming its largest consumer-discretionary names at the margin, possibly to fund the healthcare-and-activist core.
