Business History

 

   The three original founding brothers Griffith, Carl, and Lester Asplundh originally started tree trimming to finance their college educations after their Swedish immigrant father died. Griffith majored in forestry at Penn State, Carl studied finance at Wharton, and Lester was a football star at Swarthmore College, where he studied electrical engineering. After finishing school, the boys decided to go into business together to do what they knew best – tree trimming. In 1928 they borrowed $2,500 from a local bank and formed Asplundh Tree Expert. Griffith oversaw the actual tree trimming, Carl minded the books, and Les provided engineering expertise and R&D support. Even the name is redolent of things arboreal: Asplundh in Swedish means "aspen grove."​

​

   Early on, Asplundh’s business thrived because of a key insight: tree-trimming for residential customers was an ok business, but it was crowded and cyclical.  The brothers realized that commercial customers were far superior and devoted all their efforts to winning contracts with  both businesses and the government. The electric companies will always pay their bills. Mrs. Jones might not.

   The boys soon began clearing tree branches from the overhead lines of the fast-growing electric and telephone companies. Their first contract was to trim 500 trees for Pennsylvania Power & Light. While Mrs. Jones pulled in her belt during the Great Depression in the 1930s, the electric and telephone companies continued to expand, buoyed by government stimulus from FDR’s New Deal. By 1936, equipped with what was then the latest technology — hand-cranked aerial platforms and early-model chainsaws developed by Les — Asplundh had added customers as far south as South Carolina, and as far west as Illinois.

 

Post-War Expansion (1940s-1960s)

 

   The post-World War II era saw an even bigger boom in electricity demand. Driven by economic growth, suburban expansion, and the widespread adoption of electric-powered consumer appliances like the microwave, refrigerator, washing machine, and the vacuum cleaner, Asplundh continued to fire on all cylinders.

 

   Passed in 1935 (and amended in 1941), the Federal Power Act (“FPA”) gave the Federal Power Commission (now called FERC) authority over interstate electricity transmission, which promoted further grid integration. After World War II, Asplundh invented the first commercial woodchipper, which made clearing trees from the fast-growing electrical grid much more efficient.

 

   In the 50s and 60s, nuclear power plants started to offer a new, powerful source of electricity and began to contribute significantly to the grid. To accommodate the incredible baby boom population growth, suburbs started sprouting up across the country. This posed a huge problem for utilities. They had to maintain clear pathways for power lines, which were increasingly being ran through heavily wooded areas. Tree growth kept causing outages, safety hazards, and forest fires which dramatically increased utilities’ maintenance costs. To remedy this, they began hiring service providers like Asplundh with increasing frequency to maintain a clear right-of-way so that power lines could run uninhibited by brush overgrowth.

 

   Asplundh’s founders would not have known the term, but they were pioneers in what is now popularly called "outsourcing." Most of these utilities could hire their own staff of tree-trimmers, but Asplundh did it far cheaper by utilizing experienced workers and purpose-built automated machinery.

 

The Need for Innovation (1970s-1980s)

 

   By the mid-20th century, power lines had expanded significantly from its humble pre-Depression era beginnings, and the need for a more efficient tree trimming solution became readily apparent. The dangers and inefficiencies of manual trimming highlighted the lucrative potential for automation. Initially, tree trimming was done manually by Asplundh workers using hand saws and pruning shears. This was labor-intensive, time-consuming, and incredibly dangerous, especially for high, hard-to-reach branches. Being an Asplundh tree trimmer in the mid-20th century was just as risky as working in an underground coal mine. Around this time in other industries across the country, labor unions were becoming increasingly popular. The first tree trimmers workers union was organized in 1951 and in the union glory days of the 50s, 60s, and 70s, Asplundh’s labor force periodically turned nasty, and there was rock-throwing violence.

 

   By the early 70s all the founding brothers were either retired or dead, so the second generation took over. Barr Asplundh (Griffith's son) was elected president, and seven brothers and cousins were on the board of directors. A combination of both union pressure and simple youthful experimentation pushed Asplundh’s second generation to enthusiastically incorporate new machinery and trimming techniques to make the work environment safer for its employees.

 

   Like most innovations, the first steps toward mechanized tree trimming started with improving technologies that already existed. At the time, the typical equipment used in Right-of-Way (“RoW”) maintenance was a combination of manual climbing (common in urban/residential environments) and boom trucks, where workers are lifted to the height of the branches where they can trim them manually. While boom trucks no doubt improved safety and efficiency, they still required a significant amount of manual labor and were very dangerous because workers were completely exposed to falling branches.

The Invention of the Aerial Tree Trimmer

​​

   In 1980, the first real breakthrough in the industry came when a tiny company in rural Minnesota called Jarraff Industries invented the first Aerial Tree Trimmer. These devices use a series of circular saw blades mounted on a vertical boom controlled by someone on the ground within an enclosed cab. The blades are powered by hydraulic motors, allowing them to cut through thick branches very quickly. More importantly, Aerial Tree Trimmers eliminated the lethal risk of dying from a falling tree branch.

The Aerial Tree Trimmer was revolutionary for four key reasons: safety, speed, ease of use, and accuracy.

​​

   Rather than working 70 feet in the air, subjected to the elements, operators stay safe in a climate-controlled cab on the ground. It's not an exaggeration to say that this innovation has probably saved tens of thousands of lives since its 1980 invention. An aerial tree trimmer performs 5-10 times the daily work of traditional methods like bucket trucks, lifts, and climbers. A Jarraff trimmer can clear an average of 2 miles of vegetation in a day vs. a 0.5 mile average with a bucket truck. The Aerial Tree Trimmer also significantly reduced the necessary crew size from three or four with a bucket truck to just requiring one- or two-line workers.

​

Disciplined Nepotism Drives 30 Years of Growth for Asplundh
 

   Asplundh’s third generation began to take over in the mid-80s and early 90s, and quickly  made three critical decisions that transformed Asplundh into one of the most successful private companies in the country, growing revenues 11% per year for 40 years. 40 years of double-digit revenue growth. Just incredible.

               

  1. They quickly implemented aerial tree trimmers nationwide. These machines vastly improved profitability, workplace safety, and employee morale.  From the line worker’s point of view, it’s a lot more fun to sit on the ground in a climate-controlled cab moving an automated saw arm than it is to have to climb up in a bucket truck and potentially get hit by branches that were sawed manually.

  2. They grew Asplundh’s customer base by introducing new service lines to diversify outside of the core vegetation management / tree trimming services. This was done both organically and via acquisition. For the last two decades, Asplundh has acquired a new company every two to three years. In addition to vegetation management, they expanded Asplundh into a family of subsidiaries that as whole design, build, and maintain all aspects of networks for utilities, developers, departments of transportation, and municipalities. In 2015, commercial landscaping and snow removal services were added via acquisitions throughout the U.S. and Australia / New Zealand region. In 2019, infrastructure services were added to the fold with the acquisitions of Power Delivery Solutions and Burlington Electrical Test Company (see acquisition commentary within the Asplundh Investment Thesis section for further discussion).

  3. They used a unique form of disciplined nepotism to ensure that they didn’t put at risk the success their family had built for them.

​

   After estate taxes, a family business’s most lethal enemy is internal squabbling over the wealth piled up by previous generations. To avoid this kind of discord, Asplundh used a method that turned out to be simultaneously both creative and incredibly effective. They called it the "Sponsor System." The roughly 20 Asplundhs family members working at the company, even the CEO, had to oversee and sponsor different lines of business. There were no cushy spots in personnel or marketing. If you didn’t manage a profit center, then you didn’t work at Asplundh. CEO Matt Asplundh says: "No one in the family is above failure and success."

 

   This is unabashed nepotism, because only an Asplundh family member can become a sponsor, but it is highly disciplined form of nepotism. To this day, any family member that wants to work for the company must first finish college, then do something else for three years before they can apply for a position at the company. They can spend those three years either working for another company, traveling, or working towards a graduate degree. The aspirant must then get recommendations from three different family members, and at least one must be a board member.

 

   The successful candidate still doesn't have it made. They must then complete a rigorous eight-year training program. Does everyone pass it? No way. Three Asplundhs have dropped out or been asked to leave in the last decade. The recently appointed CEO's experience is pretty typical. The 56-year-old nephew of Chris Asplundh (Asplundh’s legendary CEO from 1992-2010) originally started working for the company as a tree-trimmer servicing Philadelphia Electric Co.'s lines. He then supervised Asplundh crews in Minnesota and Texas. After four years of that, he was sent to oversee 200 workers in Iowa, before moving to Nebraska as the director of a 300-employee division.

 

   He eventually worked his way up from Nebraska Group Executive all the way up to the top job over the span of 23 more years, when he became CEO in 2021. "The company is extremely demanding. If you don't want to do it, then this isn't the place to be" says Chris.  It’s no surprise that barely one in ten of the Asplundh family shareholders work for the company. Other family members have inherited the stock and are simply passive investors. Just under 20% of the company is technically owned by employees, but it's more like a traditional pension, because workers must sell back their stock at book value upon leaving the company.

​

   The fourth generation of Asplundhs are now beginning to take the helm; there are over 60 of them. How much longer can the company maintain its unique and highly successful nepotism? Under the Sponsorship System, only a few will retain jobs at the company. Some younger family members currently receive less than $50,000 a year in dividends. Most of the earnings, estimated at roughly $1.5 billion per year, either get plowed back into the business or are used to pay down the modest amount of long-term debt Asplundh took out to fund some recent acquisitions.

 

   Because Asplundh is so profitable, historically the family didn’t have much need for outside capital. But as more members of the family wanted to realize some liquidity over the years, the only likely buyer was Asplundh Tree, and the company had a policy of only paying a conservatively stated book value.

 

   Being an Asplundh certainly was no guarantee of affluence. This changed in 2017, when the Luxembourg-based behemoth CVC Capital Partners finally convinced the Asplundh family to sell them a minority stake. While the official price and ownership percentage CVC purchased was never released, it was a minority deal that valued Asplundh at roughly $10B, or about 14x its trailing EBITDA at the time.

 

   To reduce a potentially massive tax bill for certain members of the family, the Asplundhs made CVC purchase its stake within a specific buyout fund dedicated to retaining holdings for at least a decade or more (rather than the typical three-to-five-year private equity hold period). While I’m by no means a tax expert, if I had to speculate, the book value of Asplundh’s shares prior to the CVC investment was likely astronomically lower than the implied $10 billion valuation because Asplundh’s business model is so fixed asset heavy. They can (and should) use all sorts of depreciation write offs to report very little taxable income. It’s a cash-flow gusher of a business model.

 

   Family businesses are notoriously fickle. I’ve heard from a few different people that the family’s decision to take outside capital for the first time was primarily driven by two factors – tax reduction and capital markets expertise.

 

  1. Tax reduction. At the time, investors and business owners like the Asplundhs were concerned about potential upcoming changes in the tax code. Remember, the investment was made in 2017/2018. This was right around all the hoopla of whether Trump’s tax reform would end up getting repealed if Biden won the next election. Didn’t end up happening (yet) but it was a valid concern at the time.

  2. Capital markets expertise. While I’m sure a bit of the driving force was some family members understandably wanting to take some chips off the table and realize some liquidity, I’m told they were even more interested in bringing in some financial “deal guy” expertise to accelerate Asplundh’s recent acquisition spree. Having a tenured investor like CVC on their side of the negotiating table changes the game when you're raising billions of publicly-traded debt financing. Even for a wonderful business like Asplundh, raising capital in the public markets can be a headache, especially if you’ve never done it before. Just recently, Asplundh used some of the capital from its recent bond offering to acquire Voltyx Energy Solutions (May 2024) and Chevron Group (June 2024).

 

Asplundh Investment Thesis

 

   PE firms have been salivating for a shot at owning Asplundh for decades. The business is an LBO wet dream for a multitude of reasons: (a) they hold the dominant #1 position within a highly fragmented market, (b) the revenue base is highly recurring, (c) trees still grow in a recession, making the vast majority of Asplundh’s business completely independent of economic cycles, (d) its end market grows at a high single digit rate due to accelerating regulation and other climate-related factors, (e) they enjoy a highly variable cost structure, and (f) they operate in an industry with extremely high barriers to entry.

 

a. They hold the dominant #1 position in a highly fragmented market. Asplundh is the #1 player in the vegetation management space by a mile. To give you some context, Asplundh is three times larger than its nearest competitor, Kendall Tree. Asplundh has roughly 50% market share within the $8 billion Utility Vegetation Management sector. They employ 33,000 people and are one of only three service providers that have a truly national presence. Although vegetation management is inherently a local business, national scale is a huge competitive advantage when it comes to servicing larger commercial and industrial clients that tend to have a very broad geographic presence (think electric utilities, rail roads, power producers, municipalities, etc.).

 

   Like in most industries, scale provides better leverage when negotiating long-term contracts with large customers who generally seek national providers with a strong safety record, longevity, and a turn-key solution. Asplundh’s scale also enhances its profitability by allowing for more operating efficiencies. Being able to afford expensive equipment (i.e., aerial tree trimmers) makes Asplundh crews 5x more efficient than a single-crew sized company could ever achieve. In an industry as highly fragmented as vegetation management, this scale translates to multiple percentage points (and billions of dollars) to Asplundh’s bottom line.

 

   Over time, the combination of the sizable addressable markets in vegetation management ($8 billion), construction services (~$25 billion), and commercial landscaping ($153 billion), and Asplundh's scale, safety records, and long-standing relationships, the company will have a ton of opportunity to grow its market share organically and expand through more tuck-in acquisitions. With all due respect to long-standing family businesses, there is also typically a lot of unnecessary fat that trickles in over the years. It’s the nature of any bureaucracy. CVC will likely be a huge value add in this area as well.

 

b. High level of recurring revenue with a long-tenured customer base. After major national power outages like the 2003 Midwest and Northeast Blackout, the Federal government implemented a new regulatory framework layered with harsh penalties to incentivize (force) electric utilities to protect their infrastructure assets from ever encroaching vegetation growth (see Appendix for further regulatory discussion). These regulations have made vegetation management spending (i.e., Asplundh’s revenue base) completely non-discretionary and 100% independent of the economic cycle.

 

   Approximately, 90% of Asplundh's revenue is derived from recurring maintenance-related work projects rather than highly cyclical heavy infrastructure construction projects, so Asplundh’s cash flow is a lot easier to underwrite then a typical investment.

 

   Throughout all its growth over the past two decades, Asplundh hasn’t neglected its old clients. Four of the company's first five customers have contracted with Asplundh continuously since its inception. 20 more utilities have been customers for the past 50 years. Asplundh’s safety and quality records have allowed the company to maintain essentially the same customer base for nearly a century. Contracts last an average of three to five years and are rarely not renewed. This business is a debt underwriter’s matchmade in heaven.

 

c. Trees still grow in a recession. As mentioned, RoW maintenance is mandated by federal, state, and local regulatory authorities. Utilities must always maintain clearance distances, requiring ongoing tree trimming throughout the year, regardless of the economic environment.

 

   U.S. transmission / distribution and operating / maintenance (“T&D O&M”) spending declined only 2% in 2009 and grew 5% in 2020. Utilities have one job–providing reliable electricity, and they are 100% reliant on Asplundh to make this happen. Vegetation grows regardless of the economic cycle, providing a consistent, stable source of demand for RoW maintenance.

 

   Regulators set electricity rates based on a “bottom-up” estimate of utility expenses, including the cost of RoW maintenance. As rates are typically set on a multi-year basis, RoW maintenance spending does not correlate to year-over-year economic changes. RoW maintenance is typically the largest single maintenance expense for a utility. According to CNUC, a utility consulting firm, investor-owned utilities spend $5 billion a year on tree trimming. Utility transmission and distribution operations and maintenance spending has steadily grown 4.4% annually since 2006 (of which RoW maintenance is a significant component).

 

   This resiliency is further evidenced by Asplundh's performance through previous cycles. For example, during the Great Recession, Asplundh kept plugging away, organically growing its revenue from $2.2 billion to $2.3 billion in 2008-2009.

 

d. Multiple end market tailwinds will drive long-term market growth. A variety of long-term market trends have driven steady investment—to the tune of tens of billions of dollars a year—on initiatives to replace, upgrade, maintain, and expand T&D infrastructure. These include the increasing age of the networks, more stringent regulations, increased demand for power delivery, a greater focus on renewable energy, smart grid initiatives, and utilities’ involvement in the deployment of 5G wireless telecommunications networks (see Appendix for further discussion on end markets).

​

e. Highly variable cost structure. Asplundh clearly has a very attractive business model from a topline revenue standpoint, but it also enjoys a highly variable, labor dominated cost structure. When you combine that with relatively low capital spending requirements (around 7.0% of revenue per year) and modest working capital needs, Asplundh is clearly a highly capital efficient business. Being able to flex a large portion of your cost structure at will is a powerful arrow to have in your quiver and is a key reason free cash flow grew even in the very severe economic decline during the GR in 2008/2009.

 

   In addition, Asplundh’s can utilize heavy levels of depreciation deductions to significantly reduce its taxable income, given the high-ticket price and long useful lives of their fixed asset base (aerial tree trimmers cost roughly $300,000 per machine and can last upwards of 20-30 years with proper maintenance). Asplundh owns thousands of these, which translates to tens of millions of annual depreciation expense they can use to report less taxable income.

 

f. High barriers to entry. Asplundh's safety records, large operating scale, national footprint, massive employee base of experienced tree trimmers, and long-standing customer relationships make it damn hard (if not impossible) for a potential new competitor to enter the space in any meaningful way. Given the contractual nature of the industry, I find it hard to see a potential future where Asplundh’s market share is threatened in any serious way.

 

Asplundh Business Overview / Acquisition History

 

   Asplundh operates through three primary segments: Vegetation Management ($4.2 billion, 60% of revenue), Utility Infrastructure Services ($2.0 billion, 30% of revenue), and Commercial Landscaping ($300 million, 5% of revenue). 

 

   Since bringing in CVC in 2016, Asplundh has done a number of acquisitions on the infrastructure service side to diversify the business away from its core vegetation management segment.

​

Infrastructure Services Acquisitions:

  • Chevron Group (June 2024). New Zealand-based provider of traffic management, planning, and training services to the utility, construction, government and event sectors.

  • Voltyx Energy Solutions (May 2024). Asplundh bought Voltyx, a Maryland-based provider of engineering, design, commissioning, installation, repair, and maintenance services for the electrical grid, from private equity firm Arcline. Given Arcline’s typical investment check size, it’s fair to say to this was a pretty large acquisition (I’m told Asplundh’s largest ever), likely in the $1 billion range.

  • Burlington Electrical Test Company (“BET”) (September 2019). Purchased through Asplundh subsidiary UtiliCon Solutions Ltd. (Asplundh’s Infrastructure Services arm that maintains overhead and underground power systems, roadway lighting, traffic signals and intelligent transportation systems by doing testing and commissioning, pole inspection and treatment, AMI/AMR deployments, and storm and emergency recovery). BET is a services firm that accredits electrical technicians with certain certifications and other various tests.

  • Power Delivery Solutions (“PDS”) (April 2019). The first acquisition that Asplundh made after bringing in outside capital from CVC, when they first showed signs of expanding more on the infrastructure services side. PDS is a utility outsourced services provider that does cost estimates, permitting, surveying, drafting, project management, and reliability/feasibility/ line assessment studies.

 

Vegetation Management Acquisitions:

  • Rotor Blade (April 2016). Rotor Blade is a South Carolina-based provider of airborne vegetation management services. They have a patented aerial saw method where a helicopter flies over a tree with a line of saws dangling down on a string. The video of these things in action is pretty wild.

 

Commercial Landscaping Acquisitions:

  • T.R. Gear Landscaping (September 2015). Asplundh’s acquisition of T.R. Gear helped to continue building out its commercial landscaping subsidiary Aspen Grove Landscaping, which now represents about 5% of total revenue (~$300 million). This is a crowded space with a ton of private equity competition for deals so if I had to guess they will probably focus more on the infrastructure service side in future acquisitions, as landscaping in general is commoditized and is more of a race to the bottom on pricing. T.R. Gear provides landscaping and snow services for commercial clients in Cincinnati, Dayton, and Northern Kentucky.​​

Key Risks

 

No business is perfect, and there are some risks with Asplundh’s business model worth highlighting.

 

Labor Challenges / Union Risk. In September 2017, Asplundh paid the largest civil settlement ever levied by ICE because they knowingly employed illegal immigrants for years. If I had to guess (the timing is just too perfect), this came to light in the middle of Asplundh’s minority sale process which was closed at the end of 2017. This might be the first case I have ever come across in my entire career where the buy-side diligence benefits team actually earned their fee.

 

   Increased insurance premiums, per diem requirements, and increases in minimum wages for clearance tree trimmers and electrical utility linemen have driven unit rate increases for trimming and removals. Asplundh is eventually able to pass along 100% these increases by raising its prices, but given 75%+ of their revenue is fixed via long term contracts, a huge jump in any given year’s labor cost like we saw in 2021/2022 could potentially hurt short term profitability before they have a chance to renegotiate when the contract runs out. Contracts are usually 3-5 years, so unless Asplundh negotiates some cost-of-living clause into its contracts with utility customers (doubtful), they are temporarily hindered from being able to raise prices to match any input cost inflation.

 

Moderately capital intensive. Asplundh's capital spending (about 7% of revenue) and high dividend payout ratio somewhat limit its financial flexibility. Hard to imagine, but there is a potential for Asplundh to over-leverage themselves by overpaying on a few too many large acquisitions and find themselves in a liquidity crunch. Given the historical conservative nature of the family, I find this unlikely, but worth mentioning. 

 

Moderate exposure to gas price fluctuations. Similar to the labor cost inflation argument above, any massive spike in gas prices in a given year could hinder short-tern profitability, however this is a lot less material of an issue compared to wage inflation given the make up of Asplundh’s cost structure.

 

Regulation risk. The flip side of having your business so tied up with government regulations is that it’s (somewhat) out of the company’s control. It’s hard to picture (though not unprecedented) but there could be some strange law passed in the future that requires utilities or municipalities to spread the love and not use Asplundh for such a large portion of their RoW maintenance / service work. If you’ve ever heard of a company named Halliburton or seen the movie War Dogs, this should ring a bell. This is more of a risk in other heavily regulated industries (think defense/military spending or healthcare), but there could be a future scenario where some politician gets elected that goes on a weird vendetta against dominant utility service contractors. I suppose crazier things have happened.

 

Appendix – Utility Vegetation Management Sector Overview and Competitive Landscape

 

   The North American transmission and distribution (“T&D”) network is the aging linchpin of the country’s power system and is poised for a dramatic facelift in the coming decade. This creates a compelling opportunity set for companies that provide utility construction and maintenance services.

 

   A multitude of factors are driving an increase in spend on T&D infrastructure, including a tightening regulatory framework, the need for additional T&D mileage, and a changing, more extreme climate. Asplundh and other outsourced utility service providers stand to benefit. In 2020 alone, utilities spent close to $90 billion on T&D infrastructure, which is a 2.3x increase since 2007.

​

  As the country’s energy infrastructure expands, so too must spending on VM to properly protect this new infrastructure from encroachment of overgrowing trees. From 2015 to 2020, utilities’ T&D capital expenditures and operating expenses increased from $66 billion to approximately $90 billion. Across all utilities, the percentage of operating expenses going to vegetation management has similarly grown from 55% of a utility’s maintenance budget to approximately 75%.

​​

   In 2020, utility spend on vegetation management reached $7.6 billion, which doesn’t even include the ~$800 million spent on hazard tree removal and right-of-way clearing (those costs are capitalized).

   As shown above, spending for investor-owned utilities has increased at a CAGR of ~7% since 2008.  Vegetation management is frequently the single largest line item in a utility’s operating budget, exceeding $100 million a year for many large utilities. This is almost entirely spent on third-party suppliers like Asplundh that perform various aspects of these vegetation programs.

 

   Utility Vegetation Management (“UVM”) is the process of executing planned chemical and mechanical treatments to protect electrical infrastructure from trees and other vegetation that could potentially fall into a power line and cause a power outage. Vegetation fall-ins and contacts have historically been a leading cause of power outages, causing or contributing to over 55% of outages on transmission lines alone. There’s also a huge increase in the risk of a wildfire starting.

UVM activities and services can be grouped into three general categories: pre-planning and monitoring, treatment, and reactive repair.

 

   Pre-planning and monitoring. Evaluating, mapping, and tracking vegetation growth allows utilities to proactively plan how best to treat any identified hazardous vegetation as it grows. This can include aerial surveillance via satellite, unmanned aerial vehicles, and light detection and ranging (“LiDAR”), and is typically combined with ground patrols to spot any hazardous tree encroachments. Expert arborists are often engaged to help identify problematic vegetation species within the control areas and advise on the best methods to develop a planned treatment schedule. This plan is what T&D owners and operators (electric utilities) will submit to regulatory officials for their approval.

  • Typical Services Provided: Ground patrol monitoring, aerial mapping, vegetation management planning and scheduling.

 

   Treatment. Includes mechanical treatments (i.e., mowing, trimming of branches, and pruning), and chemical application (i.e., spraying herbicides to eliminate certain aggressive species of vegetation, applying pruning retardants to tree stubs, or injecting chemicals into tree roots to stunt growth) to actively remove and maintain vegetation. Combined application of both mechanical and chemical treatments, also referred to as Integrated Vegetation Management (“IVM”), is often more cost effective than mechanical-only treatments. When done with the guidance of professional service providers, IVM is shown to be less disruptive and more protective to the treated ecosystems. These activities are completed on a planned frequency schedule that depends on the vegetation’s growth rate, but generally occur roughly every five years.

  • Typical Services Provided: Tree trimming, right-of-way maintenance (i.e., brush clearing), herbicide application, ecosystem management.

 

   Reactive repair. Reactions to unplanned events that cause trees to fall into and trip power lines. This includes debris removal following any extreme weather events as well as emergency trimmings of any vegetation that encroached onto a power line.

  • Typical Services Provided: Storm response, line clearing (i.e., removing a fallen tree from contact with a power line).

 

   Several major national outages have been traced back to power-line interference with trees, including two blackouts in 1996 in Idaho and California, a 2003 outage that drove blackouts across the Midwest and Northeast, and a 2011 winter storm blackout in the Northeast. Each of these blackouts involved entirely preventable tree interference that caused power outages for millions of people, cost billions of dollars, and resulted in millions of lost work hours. It’s crazy to think about the knock-on effects of an extended power outage because we don’t really encounter it that much but think about the recent cold wave that almost permanently ruined Texas’s power grid a few years ago. Power outages materially impact GDP, and cost the U.S. economy ~$100 billion a year on average.

 

   Standards and regulations have without a doubt helped decrease the frequency of tree-related outages, particularly for transmission lines, but there’s still a lot of improvements that can be made. Vegetation is still responsible for over 55% of the country’s power outages. Falling trees caused the recent catastrophic wildfires in California (Sonoma (2017) and Paradise (2018)).

Evolution of the Electric Grid’s Regulatory Framework

 

   The serious consequences of the several major blackout events, particularly the 2003 Midwest and Northeast Blackout, drove the Federal government to implement a new regulatory framework layered with penalties called FAC-003. They really need to get more creative with the names of these regulations and bureaucratic committees, it’s hard to keep up.

   FAC-003 was designed to ensure that utilities appropriately protect their T&D assets from encroaching vegetation. It outlines six key requirements: (1) maintaining a minimum vegetation clearance distance between power lines and vegetation; (2) documenting maintenance strategies and procedures; (3) notifying appropriate control centers of conditions that could cause flash-over events; (4) taking corrective action to eliminate potential flash-over events; (5) inspecting vegetation conditions annually; and (6) completing annual work to prevent flash-over events. Non-compliance with any of these can result in fines of up to $1 million per day that the utility is out of compliance.

 

   This has made spending to protect and ensure the reliability of T&D infrastructure from vegetation hazards completely non-discretionary, which is great for Asplundh, not so much for the utilities. In short, more regulation leads to more utility maintenance spending, which leads to more revenue for Asplundh. Investor-owned utilities now spend ~$8 billion annually on routine vegetation management, which will continue to grow (no pun intended) in the next few decades.

 

In addition, to increased regulation, several factors will drive continued growth in T&D infrastructure spending in the coming decades.

  1. Power line mileage growth. Small power sources are being connected to give people in very rural areas more reliable access to electricity. This means that the amount of power lines that need to be tree trimmed will continue to increase dramatically. More electricity demand = more tree trimming.

  2. Adoption of advanced pruning methods. Developing more environmentally friendly tree trimming methods to ensure minimal impact to managed ecosystems requires employing expert arborists, utilizing more advanced tracking, monitoring, and mapping technologies, and more wholistically managing vegetation. There are probably only three or four companies in the entire vegetation management industry with the appropriate scale to actually implement any of these advanced methods.

  3. Increasing temperatures and extreme weather events. Increasing temperatures and prolonged seasons of warm weather increase vegetation growth rates, thereby shrinking pruning cycles and increasing the frequency of vegetation treatment. In addition, the increasing frequency/severity of extreme weather events drastically increases the probability of trees outside the right-of-way falling into and tripping electric power lines.

  4. Aggressive clean energy and carbon-reduction goals. The nation’s electricity grid will require significant changes and expansion to accommodate the various clean energy and carbon-reduction goals established across state and federal governments. Studies suggest that the capacity of the nation’s transmission system alone may have to be doubled to meet the Biden Administration’s aggressive climate goals. As a result, CapEx investments in T&D infrastructure are projected to exceed $70 billion in 2024 and 2025, including the construction of some 13,000 miles of new transmission lines. As a result, T&D power line mileage expansion is expected to drive growth in annual maintenance budgets beyond current spending levels. This increased maintenance spend will be composed largely of more investment in vegetation management.

 

Competitive Landscape

​

   As you can see below, the utility vegetation management market is pretty much an oligopoly dominated by Asplundh and three or four other players. The “All Other” segment is made up of hundreds, if not thousands, of local mom-and-pop single or double crew outfits. Given the country’s vegetation density, the vast majority of these smaller companies are located in the Southeastern and Northwestern states.
