The Harbor Mid Cap Value Fund returned 4.76% in Q1 2026, outperforming the Russell Midcap Value Index's 3.68% return during a turbulent quarter marked by AI concerns, tariff uncertainty, and Middle East geopolitical shocks. The fund benefited from strong stock selection in Information Technology, Energy, and other sectors, with notable contributors including Sandisk (AI-driven storage demand), energy holdings like Matador Resources and APA Corp (oil price surge from Iran conflict), and CF Industries (fertilizer price spike). The quarter saw continued rotation from mega-cap technology toward smaller, value-oriented stocks, which favored the fund's positioning. Portfolio activity included trimming winners like Sandisk and Matador, initiating positions in top-ranked Smithfield Foods and Commercial Metals, and selling Flex due to valuation concerns. The fund trades at an attractive 10x forward earnings versus 16x for the benchmark, with management remaining committed to their disciplined quantitative value approach and excited about mid- and small-cap value opportunities.
Mid-cap value stocks remain attractive while largest companies are expensive, with the fund positioned to benefit from ongoing rotation toward smaller, value-oriented stocks through disciplined quantitative stock selection.
Manager remains committed to disciplined value investment approach and is excited about opportunities among mid- and small-cap value stocks. Fund is attractively priced relative to benchmark at 10x forward earnings versus 16x for value benchmark.

| QUARTER | THEMES | TAGS |

AIAI concerns disrupted technology shares in January as new capabilities threatened the Software-as-a-Service business model. The fund benefited from AI-driven demand for storage through holdings like Sandisk, while also noting potential AI disruption risks in sectors like online travel. |
Software Storage Disruption Technology SaaS |
OilEnergy sector surged 38% as crude oil prices soared above $100 per barrel following the US-Israeli military operation against Iran and closure of the Strait of Hormuz. Energy holdings including Matador Resources, APA Corp, and Halliburton were significant contributors to performance. |

Small CapsSmall- and mid-cap stocks fared better than large-cap during the turbulent quarter, with Russell 2000 gaining 0.9% while Russell 1000 declined 4.2%. Manager finds small-cap and mid-cap stocks remain relatively attractive while largest companies are expensive. |

| 2025 Q4 |
AIAI remains transformative but markets are shifting from hype to show-me phase. The industry has spent over $400 billion on capex while producing roughly $50 billion in revenues. Physical constraints like power shortages and build delays are challenging assumptions of frictionless scaling. |
Artificial Intelligence Technology Capex Infrastructure Valuations |
Private CreditPrivate markets are finally offering opportunity as supply and demand balance has shifted. Traditional institutions are over-allocated, distributions have dried up, and scarcity of capital gives patient liquidity providers leverage on price and terms. Firm is launching a private markets fund in Q1 2026. |
Private Markets Illiquid Strategies Secondaries Real Estate Credit | |
Commercial Real EstateReal estate is where price and replacement cost have meaningfully diverged. Valuations have fallen approximately 20% since 2022 while construction costs have risen 20-30%. This gap creates a powerful setup for patient capital to buy high-quality assets below replacement cost. |

| 2025 Q3 |
Trade PolicyTrade tensions dominated headlines with Liberation Day tariffs affecting imports from China, Europe, and Canada causing significant market volatility. Markets initially dropped 19% following tariff announcements before recovering as policy reversals and bilateral negotiations helped stabilize conditions. Long-term implications of trade policy changes remain uncertain for supply chains and corporate profitability. |
Tariffs China Supply Chain Inflation Retaliation |
AIInvestment in AI infrastructure remained a key driver of performance, bolstering demand for semiconductor, cloud, industrial, and technology equipment companies. Information Technology led all sectors with 21.99% gains in the quarter, driven by continued AI infrastructure investment themes. |
Infrastructure Semiconductors Cloud Technology Equipment | |
Commercial Real EstateCBRE Group, the world's largest commercial real estate services company, faced headwinds as tariff uncertainty caused customers to delay decisions on new leases, property purchases, and management opportunities. Despite challenges, the broader return to office trend is expected to continue supporting the sector. |
Office Leasing Property Management Return to Office Services | |
AerospaceWoodward demonstrated strong performance in aerospace with better-than-consensus earnings driven by strong demand for new defense equipment and higher commercial aftermarket activity. The company showed continued share gains and margin expansion through transformation from component to systems supplier in commercial aircraft engines. |

ValueValue stocks were left behind in the market rally and continue to trade at significant discounts to their growth counterparts, enhancing the potential for outperformance if valuations between growth and value stocks revert to a more normal, historical average. The Fund trades at just over 10x forward earnings and 7x cash flow, which are significant discounts to the core and value benchmark. |

AINRG Energy continues to benefit from rising electricity demand needed to fuel the AI revolution. The rally was powered primarily by large-cap technology stocks, with the Information Technology sector gaining 24% and contributing more than half of the S&P 500's quarterly gains. |

| TICKER | COMMENTARY |
|---|---|
| WDC | The top-performing stock in the Information Technology sector once again was Sandisk, as the strong performance of stocks related to the AI-driven demand for storage continued. While we continue to hold Sandisk, we trimmed the position in the quarter given the run-up in the stock. |
| ARW | Arrow Electronics also did well in the Information Technology sector after reporting strong fourth quarter earnings with the recovery in the semiconductor market and strong demand for AI infrastructure and cloud services. |
| MTDR | Matador Resources and APA Corp., both E&P companies, were up significantly due to the Middle East conflict. We trimmed our exposure to Matador Resources. |
| APA | Matador Resources and APA Corp., both E&P companies, were up significantly due to the Middle East conflict. |
| HAL | Halliburton in the equipment and services group and refiner HF Sinclair also did well in the quarter. |
| DINO | Halliburton in the equipment and services group and refiner HF Sinclair also did well in the quarter. |
| CF | Other top contributors in the quarter included CF Industries in the Materials sector. Much like Energy stocks, CF Industries benefited from the turmoil in the Middle East, as fertilizer prices spiked in the quarter. |
| ALSN | Allison Transmission rose to new highs in the first quarter, helped by optimistic 2026 earnings and revenue expectations. |
| FOXA | Fox Corp. was down nearly 20% over concerns about falling net income and ongoing subscriber declines. |
| ANGI | Angi's stock came under pressure after reporting disappointing fourth quarter revenue and earnings. We did not make any trades in Expedia, Fox, or Upwork, but added to our position in Angi. |
| EXPE | While Expedia Group beat fourth quarter 2025 earnings estimates, weak travel demand to and from the U.S. and the potential for AI disruption in the online travel business weighed on the stock in the first quarter. We did not make any trades in Expedia, Fox, or Upwork, but added to our position in Angi. |
| UPWK | Upwork declined after reducing 2026 guidance. We did not make any trades in Expedia, Fox, or Upwork, but added to our position in Angi. |
| SFD | We initiated a position in Smithfield Foods, the largest pork producer in the U.S. in the packaged foods and meats industry. The company went public in a January 2025 IPO after being taken private in 2013. Smithfield Foods ranks high on multiple cash flow and forecast earnings measures, our two most important blocks of valuation measures. Overall, the stock ranks in the top 5% in our stock ranking universe, which led to the first quarter purchase. |
| CMC | We also initiated a position in Commercial Metals, a steel company in the Materials sector. The stock ranks high on multiple cash flow and forecast earnings measures, our two most important blocks of valuation measures. Overall, the stock ranks in the top 5% in our stock ranking universe, which led to the first quarter purchase. |
| FLEX | We sold our position in Flex in the Information Technology sector. Flex has done extremely well the past few years and was up over 100% in the trailing 12 months. While momentum kept the stock in our hold range for some time, earnings and cash flow did not keep pace with the stock's price, and it became less attractive from a valuation perspective. While the company was buying back shares, it did not pay a dividend. The overall rank fell out of the hold range in the first quarter, and the stock was sold. |
| JBL | We trimmed our position in Jabil, also in the Information Technology sector. Jabil has done well in recent years as the company has capitalized on the rapid growth of AI. While we continue to hold the stock, the ranking has deteriorated as earnings and cash flow have not kept up with the price increases. However, it remains in our hold range even though valuation scores have deteriorated. The strong momentum scores and the company's aggressive stock repurchases are both positives in our model. Given the run-up in the stock, we trimmed our position in the first quarter. |
