How Micron's $50 Billion Boise Buildout is Reshaping Its Hometown

Dave Petso, a wealth manager in Boise since the 1980s, has witnessed his business weather numerous economic downturns. For most of his 45-year career, Micron, the local maker of computer memory, was considered a stable but unexciting tech company and a poor investment. However, the current artificial intelligence boom has transformed Micron into one of the most sought-after stocks, significantly boosting the wealth of many of Petso's clients.

He now helps Micron employees manage their substantial stock gains, with portfolios that have grown from tens of thousands to hundreds of thousands or even millions of dollars. This rapid increase in wealth has led to significant diversification needs for these employees.

Across Boise, a city known for its outdoor recreation and Boise State University's distinctive blue turf, Micron's growth is evident. The company is building two new chip manufacturing facilities, projected to create over 17,000 jobs, including 3,500 directly at Micron, which already employs about 7,000 people in the area. This expansion is driving job growth, new construction, a vibrant dining scene, and an influx of new residents.

However, this rapid expansion also brings challenges. Residents report increased traffic, rising housing costs, and a shift in local culture due to an influx of people from California and other regions. Zillow data shows that average rental prices in Boise have risen 4.3% in the past year, contrasting with a national decline.

Jason Crawforth, a longtime Boise resident and tech entrepreneur, notes that the city's previously low cost of living was a key advantage. While his net worth has increased due to his Micron investment, he observes that a significant portion of the community does not directly benefit from this growth. CNBC spoke with various individuals in Boise to understand the impact of the current boom and Micron's ambitious $50 billion expansion plan. They describe Boise as an unexpected beneficiary of the global AI buildout, striving to maintain its identity while navigating the inherent volatility of the tech industry.

Despite the positive trajectory, Micron shares experienced a 29% drop in July, marking their worst monthly performance since 2002. Shareholders are hopeful this was a temporary correction rather than a harbinger of future declines, with the stock showing a 14% increase in August.

Boise and the Global Memory Race

Founded in Boise nearly 50 years ago, Micron established its first chip fabrication plant in 1981, specializing in DRAM (Dynamic Random-Access Memory). DRAM continues to be a significant revenue driver, accounting for 76% of Micron's revenue in its latest quarter. DRAM is crucial for high-bandwidth memory (HBM), a component essential for the powerful processors used in AI. The high demand for HBM has led to a global shortage and soaring memory costs, impacting the prices of consumer electronics like Apple's MacBooks and iPads.

The three main global suppliers of HBM – SK Hynix, Samsung, and Micron – are all investing heavily in new manufacturing facilities. SK Hynix and Samsung are building massive plants in South Korea. Despite a recent market pullback, these companies have seen substantial stock market gains, with Micron leading the pack, up nearly 670% in the past year.

Micron CEO Sanjay Mehrotra, who became a billionaire earlier this year, sees Boise as a strategic location for bolstering U.S. manufacturing. The first of Micron's two new Boise fabrication plants is slated for completion in 2027, marking the U.S.'s first front-end facility for cutting-edge memory manufacturing. Currently, most of Micron's advanced memory is produced internationally.

The expansion includes supporting infrastructure like utility and water-treatment buildings. Idaho Power has indicated that Micron's growth is not expected to increase electricity bills for other customers. Additional AI-driven development in the area includes Meta's $800 million data center in Kuna, Idaho, and new offices from Micron suppliers like Lam Research and cleanroom builder Exyte. Micron's long-term goal is to produce 40% of its DRAM in the U.S. by 2035, with an investment of $250 billion, supported by government incentives.

Micron is a cornerstone of Boise's economy, alongside other local enterprises like the Albertsons grocery chain and the J.R. Simplot potato empire. JT Belnap, founder of Treasure Valley Financial Planning, now primarily manages the wealth of Micron employees. He reports a surge in calls from Micron employees nearing retirement, many of whom are accelerating their retirement plans due to their stock gains. Some are donating stock to charities for tax benefits, while others are making significant purchases, such as an $80,000 truck.

Belnap emphasizes the importance of allowing individuals experiencing sudden wealth to enjoy their gains.

Selling Stock to Buy Jewelry and Homes

Lisa Zimowsky, owner of The Diamond Girls jewelry boutique, has seen a 60% increase in sales this year, attributing it in part to customers selling Micron stock. She notes that individuals who received quarterly bonuses when the stock was much lower are now making significant purchases. Zimowsky believes Micron's impact on Boise's economy is substantial.

The real estate market is also experiencing a boom. Sheila Smith, a local real estate agent, observes a high demand for homes and a shortage of listings near Micron's headquarters. She notes that some contractors involved in building the new fabs are purchasing homes, a departure from the typical behavior of temporary workers.

Mortgage broker Gerald Robinson reports consulting with multiple Micron clients looking to buy homes, with many exercising stock options to finance their purchases. Some clients have opted to sell stock and buy properties outright, bypassing mortgage financing.

Micron confirms that stock awards are a key strategy for talent recruitment and retention, with stock-based compensation increasing significantly. April Arnzen, Micron's chief people officer, highlights the company's aim to make employees owners and stakeholders in its success.

Long-time residents like Jason Crawforth, who invested in Micron early on, have seen substantial wealth growth. However, this has also led to personal dilemmas, such as an unintentional imbalance in stock gifts between family members.

A City's New Chapter

With increased wealth and housing demand, concerns are rising about Boise's affordability for those not directly benefiting from Micron's growth. Median home sale prices in Boise have increased more than the national average. Robinson points out that lower-income residents may be priced out as wages fail to keep pace with rising home prices.

Ada County has seen significant population growth, with many new residents moving from California, Washington, and Oregon, attracted by Boise's perceived lower cost of living and lifestyle amenities. Zimowsky notes a visible shift in demographics and consumer behavior, with a rise in designer goods and an increased awareness of luxury brands.

Boise's cultural and entertainment offerings have expanded significantly. Concerts at Boise State's stadium and a growing dining scene have transformed the city into a more vibrant destination. Chef Kris Komori, who relocated to Boise in 2013, has witnessed this transformation firsthand, with a burgeoning restaurant scene and increased development.

KIN Boise, a high-end restaurant, is a popular spot for Micron employees entertaining clients, showcasing the city's enhanced amenities. Komori observes a continuous influx of new restaurants, contributing to the city's evolving culinary landscape.

Scaling Challenges

Petso, who has lived in Boise for decades, appreciates the city's newfound vibrancy despite some challenges. He notes the packed restaurants as a sign of the city's economic health.

Micron acknowledges the pressures of its rapid expansion, particularly concerning transportation and housing. The company is actively collaborating with local and state authorities to address these issues. Micron has made commitments to housing initiatives and is exploring roadway investments. They have also established a childcare center and are investing significantly in workforce development, education, and community initiatives across Idaho.

The company supports educational institutions like Boise State University and the College of Western Idaho through various programs and sponsorships, aiming to cultivate future talent. Despite the visible construction and community efforts, concerns persist about the long-term sustainability of the memory boom.

Crawforth experienced the volatility of the market firsthand with the July stock drop, which significantly impacted his net worth, though he acknowledges overall gains. Petso draws parallels to the dot-com bubble of 1999, when a similar tech frenzy led to significant wealth for some but also painful losses for those who didn't diversify. He is currently advising his clients to trim their holdings to mitigate potential future risks, drawing on his extensive experience in navigating market cycles.
