McGrath RentCorp (MGRC) | The Buildout — AI Infrastructure
The Verdict
McGrath RentCorp owns fleets of physical assets and rents them by the month. Its modular buildings serve as temporary offices, classrooms, clinics and dormitories on construction and institutional sites. Its steel containers provide portable storage. Its TRS-RenTelco division rents electronic test equipment that technicians use to validate fiber, copper and wireless networks, and data-center commissioning work is a named driver of that demand. The company does not build AI chips or servers, and it does not engineer the projects it serves. Its link to the buildout runs through the temporary space and test gear that large construction sites consume.

What We Like
- TRS-RenTelco is accelerating across two consecutive quarters: rental revenue grew 13% in Q1 2026 and 17% in Q2 2026, with adjusted EBITDA up 29% to $25M and rental margin at 48%, up from 44%.
- Mobile Modular, the largest segment at $150M of Q2 2026 revenue, posted its first sequential utilization improvement since 2022 — average utilization of 70.1% and an exit rate of 70.6%, with bookings up 11% and units on rent up four months in a row.
- Management raised full-year gross rental equipment capex to $200M–$220M specifically to support TRS, while holding the revenue and adjusted EBITDA midpoints at $970M and $369M.
- The balance sheet has room: a $725M credit facility completed 2026-05-11 runs to 2031, leverage is 1.65x against a 2.75x covenant ceiling, and buybacks resumed this year at $27M year to date after management said the company had not repurchased shares since 2020.
- Cash conversion is strong: trailing-twelve-month free cash flow of $209.6M against $152.8M of net income is a 137% conversion rate.
What We’re Watching
- Second-half execution: Enviroplex must reach a mid-40s full year from an $8M first-half base, and the delayed Mobile Modular and Enviroplex sales projects — described by management as under contract — need to recognize by year-end.
- Portable Storage keeps eroding: adjusted EBITDA fell 23% in Q2, average utilization slipped to 58.3% from 61.1% and rental margin to 80% from 83%, and management does not expect a recovery this year.
- Leverage rose from 1.51x to 1.65x in one quarter with capex raised and buybacks running, and a $60M Series E note at 2.35% matured June 16, 2026 and is a refinancing item.
- The data-center share of revenue is not disclosed and not tracked as a category; management declined to size it, so the scale of the AI-linked business is unknown.
The thesis reads as intact but composition-shifted. The rental core is growing, TRS is accelerating, and the largest segment posted its first sequential utilization improvement since 2022, while the headline declined on equipment-sales timing. Management held its full-year revenue and adjusted EBITDA midpoints and put more capital behind the strongest division. The case now rests on two checkable deliverables inside two quarters: the second-half Enviroplex and Mobile Modular sales catch-up, and the durability of the modular utilization turn. The open question is whether the data-center-driven TRS cycle lasts long enough, and the second-half catch-up lands, so that the full-year guide does not depend on a single quarter.
Earnings Beat
Q2 2026 revenue was $221.1M, down 6% from a year earlier. Net income was $33.7M, or $1.37 per diluted share, against $36.0M, or $1.46, a year ago, and company-reported adjusted EBITDA fell 4% to $83M. Rental operations revenue rose 6%; the decline came from lower new equipment sales, with Mobile Modular sales revenue at $31.2M, down $9.3M, and Enviroplex revenue at $4.6M versus $19.9M as project completions shifted into the second half.
| Metric | Q2 FY2026 | Q1 FY2026 | Q2 FY2025 | YoY |
|---|---|---|---|---|
| Revenue | $221M | $198M | $236M | −6.2% |
| Gross margin | 48.8% | 46.2% | 44.9% | +390bps |
| EBITDA | $82M | $71M | $84M | −2.2% |

| Mobile Modular average utilization | 70.1% | 70.0% | 73.7% | −4.9% |
Data centers a main contributor to that growth. It feels like we are still in the early to mid-innings of that data center build out.— Phil Hawkins, Chief Executive Officer, 2026-07-29
Management tone: Management's tone shifted from steady on the first-quarter call to encouraged but deliberately hedged on the largest segment, and noticeably more constructive on TRS. Hawkins called the modular utilization move the first sequential improvement since 2022 and said management believes the trend turned, then added that it may not move up every quarter consistently; Pratt described the same signs as encouraging but as just the beginning of the turn. On TRS, management said demand remains strong across several end markets with no immediate sign of slowing, and backed that with capital rather than adjectives. On Portable Storage it removed any expectation of a 2026 recovery, and on education it said the vertical is not likely to be a near-term growth driver. A Middle East risk factor flagged on the first-quarter call was not mentioned on the second.
Management Guidance
For full-year 2026, as updated on the 2026-07-29 call, management guided total revenue of $955M–$985M, adjusted EBITDA of $360M–$378M and gross rental equipment capital expenditures of $200M–$220M. The revenue range was tightened around a midpoint unchanged from the prior guide, the adjusted EBITDA midpoint held at $369M, and capex was raised from $180M–$200M to support incremental investment in TRS. Management said it continues to expect strength in the Modular business, that stronger-than-expected TRS performance should offset weaker performance at Portable Storage, and that Enviroplex performance should be similar to 2024 — a mid-40s revenue year with a very strong second half and, in management's words, most likely both quarters showing healthy sales.
Trajectory
Quarterly revenue has moved unevenly — $256.4M in Q3 FY2025, $256.8M in Q4 FY2025, $198.5M in Q1 FY2026 and $221.1M in Q2 FY2026 — and the year-over-year comparison is decelerating. The rental core is the part growing: rental operations revenue rose 6% in Q2 while total revenue fell 6%, with new equipment sales at Mobile Modular down $9.3M and Enviroplex at $4.6M against $19.9M. Margins diverge by segment: TRS rental margin rose to 48% from 44%, Mobile Modular fell to 55% from 58% with inventory-center costs up $2.1M, and Portable Storage slipped to 80% from 83%. Management frames the Mobile Modular cost increase as preparation for expected stronger second-half shipment levels.
The Model
The model's locked projections put FY+1 revenue at 972M and EBITDA at 370M, a 38.1% margin, and FY+2 revenue at 1,045M and EBITDA at 408M, a 39.0% margin. FY+1 sits essentially at management's guided FY2026 revenue midpoint of $970M and just above its guided adjusted EBITDA midpoint of $369M. The FY+2 step carries revenue about 7.5% above the FY+1 level, and the source-named drivers behind the rental growth — data-center-driven TRS demand and modular geographic expansion across the Pacific Northwest, Midwest and Northeast — sit in the two segments doing the near-term work.

For full-year 2026, as updated on the 2026-07-29 call, management guided total revenue of $955M–$985M, adjusted EBITDA of $360M–$378M and gross rental equipment capital expenditures of $200M–$220M. The revenue range was tightened around a midpoint unchanged from the prior guide, the adjusted EBITDA midpoint held at $369M, and capex was raised from $180M–$200M to support incremental investment in TRS. Management said it continues to expect strength in the Modular business, that stronger-than-expected TRS performance should offset weaker performance at Portable Storage, and that Enviroplex performance should be similar to 2024 — a mid-40s revenue year with a very strong second half and, in management's words, most likely both quarters showing healthy sales.
What Could Go Right — and Wrong
- TRS rental growth holds near the second-quarter pace of 17% and the raised capex program converts into fleet and revenue on schedule.
- Mobile Modular utilization rises for a second consecutive quarter, turning the four-month shipments-exceed-returns streak into a durable trend rather than a single-quarter turn.
- The contracted Enviroplex and Mobile Modular sales projects convert in the second half, delivering the mid-40s Enviroplex full year and putting the timing claim beyond dispute.
- Portable Storage stabilizes near current utilization and margin levels instead of eroding further.
- An acquisition from the pipeline management describes as active adds regional density and Mobile Modular Plus cross-sell on the template the company outlined.
- The delayed sales slip a second time, leaving the second-half preparation costs and the raised capex without revenue to absorb them.
- TRS rental growth decelerates from 17% toward single digits while Portable Storage is still declining, removing the offset the full-year guide depends on.
- A large customer return could break the modular shipments-exceed-returns streak — education returns were already partially offsetting the utilization improvement.
- OEM supply constraints delay TRS fleet additions; Keysight, a documented manufacturer of the fleet, has said supply will remain the governor of near-term revenue.
- Leverage keeps climbing from 1.65x while earnings do not follow, narrowing room for buybacks and acquisitions against the 2.75x covenant ceiling.
Looking Ahead
Over the next twelve months the question is whether the second half delivers what the first half deferred. Management guides FY2026 revenue of $955M–$985M and adjusted EBITDA of $360M–$378M, with Enviroplex expected to produce a mid-40s full year from an $8M first-half base and the delayed Mobile Modular sales projects described as contracted and in the pipeline. TRS is expected to do the offsetting work against Portable Storage weakness, funded by the raised capex program, and management says demand there shows no immediate sign of slowing. Beyond the guide, management pointed to an active M&A pipeline and to a possible electronic-test-equipment maintenance and refresh revenue stream for which it says it still does not have a good feel.

The Company
McGrath RentCorp is a diversified business-to-business rental company. Its 10-K describes three rental divisions — relocatable modular buildings, portable storage containers and electronic test equipment — alongside a fourth reportable segment, Enviroplex, which manufactures and sells modular classrooms. The assets sit on other companies' projects: modular buildings serve as classrooms, temporary offices, sales offices, construction field offices, restroom buildings, health care clinics and child care facilities, while steel shipping containers offer what the filing calls a flexible, low cost alternative to warehousing. TRS-RenTelco rents the test equipment used to validate fiber, copper and wireless networks, and management names data centers as a main contributor to that segment's growth.
The company owns and operates its fleet rather than engineering projects or manufacturing the units it rents, with the exception of Enviroplex's classrooms. Period-end rental equipment at cost across segments was $1,988,993 thousand at March 31, 2026. Operations run through a national inventory-center network — Livermore, Mira Loma, Selma, Pasadena, Grand Prairie, Auburndale, Arcade, Fredericksburg and Concord — plus a 117,000 sq ft leased TRS-RenTelco facility in Grapevine, Texas, a sales office near Montreal and a 108,000 sq ft Enviroplex factory in Stockton, California. No new factory or inventory-center announcement appears in the source material, so the raised capex is fleet rather than facilities.
Business Segments
Competitive Landscape
Management describes the competitive picture differently by division. On large modular projects Hawkins said the company's deep team experience, operating infrastructure and the scale of its modular solutions offerings are shared with very few competitors — a management assertion, not a disclosed market-share measure. Portable Storage is described as highly competitive, with management citing lower industry utilization and lots of people trying to get units out on rent, plus pressure on rental-related-services margins in a competitive environment. TRS-RenTelco intermediates between the manufacturers that build test equipment and the customers that use it; the 10-K discloses no patents or proprietary technology behind that position.

Supply Chain
McGrath sits between equipment manufacturers and the contractors, operators and public institutions that rent its fleet. Its fleet is bought rather than built — modular units from third-party manufacturers and test equipment from named OEMs. No supplier names McGrath in the source material.
