Despite volatility, demand for AI infrastructure continues to outstrip supply. Cloud computing continues growing and supporting innovation. Microsoft Azure showed strong 39% year-over-year growth despite capacity constraints, with commercial bookings surging 111% and remaining performance obligations up 51%. Strong performance from specialty diagnostics and therapeutics companies. Natera showed strong earnings with higher test volumes and favorable reimbursement dynamics. Cidara Therapeutics was acquired by Merck for $9.2 billion based on its promising influenza prevention drug. |

| TICKER | COMMENTARY |
|---|---|
| CDTX | Cidara Therapeutics is a biotechnology company developing drug-Fc conjugate (DFC) therapeutics, with its lead program CD388, an investigational long-acting, strain-agnostic antiviral designed to prevent influenza infection in individuals at higher risk of complications. CD388 was supported by compelling Phase 2b NAVIGATE results and advanced into the Phase 3 ANCHOR study, positioning it as a potentially first-in-class, single-dose prophylactic option for influenza prevention. Share contributed positively after Merck announced an all-cash agreement to acquire Cidara for approximately $9.2 billion. |
| GOOGL | In the third quarter, Google, Kairos Power, and the Tennessee Valley Authority announced a major collaboration centered on a novel power purchase agreement. Google followed this announcement with another significant step forward. On October 27, Google and NextEra Energy announced plans to restart the Duane Arnold Energy Center. |
| META | On January 9, Meta Platforms unveiled a new agreement with Vistra—the largest generator of competitive electricity in the United States—as well as with TerraPower and Oklo. The announcement builds on Meta's agreement last year with Constellation Energy and positions the company to become one of the largest corporate purchasers of nuclear-generated electricity in the United States. |
| MRK | Top gainers in the Fund this quarter included Merck (+26%) |
| MSFT | MSFT was a detractor in 4Q25 following its fiscal first-quarter 2026 earnings report released on October 29. While results were better than expected operationally, investor reaction was driven by guidance and capital expenditure intensity rather than headline performance. Revenue grew 17% year-over-year, exceeding consensus expectations, and Azure revenue increased 39% year-over-year, also ahead of estimates. However, management guided to a sequential deceleration in Azure growth in fiscal Q2, signaling some moderation after a period of exceptional demand. |
| NBIS | Nebius continues to be viewed more like an AI infrastructure 'off-take' platform than an emerging AI-first cloud platform. The Microsoft agreement signed in September 2025 is a five-year commitment worth ~$17.4B (with options taking total value to ~$19.4B) for internal workloads and is anchored by dedicated capacity delivered from Nebius' new Vineland, New Jersey data center. |
| NTRA | Not owning Natera, Inc. (NTRA) detracted from performance. The stock rose after its earnings announcement, signaling a strong revenue beat. |
