Five-year commercial agreement simplifies enterprise adoption and scaling of Outrider self-driving yard trucks for YMX customers

HENDERSON, Nev., and HENDERSON, Colo. — October 1, 2026 — YMX Logistics, a leading national provider of integrated yard logistics for enterprise shippers, and Outrider, the leader in autonomous yard vehicles for logistics hubs, today announced a strategic partnership to expand the deployment of self-driving, zero-emission yard trucks at YMX customer sites. Under the five-year commercial agreement, YMX will operate and support the Outrider System in large enterprise customers' yards to deliver safer, more productive supply chain operations.

The agreement represents Outrider's most comprehensive channel relationship to date and establishes YMX as a full-service option for enterprise shippers to adopt and scale autonomous yard operations. The non-exclusive partnership combines Outrider's self-driving technology with YMX's comprehensive service offerings, giving customers a turnkey path to automating trailer spotting with less deployment complexity and lower capital requirements.

"Outrider's self-driving yard trucks are a strategic addition to our Autonomous Yard Operating System, expanding how we use technology to execute yard operations and create value for our customers," said Matt Yearling, CEO of YMX Logistics. "We selected Outrider because of its industry-leading approach to system safety, use of advanced AI capabilities across diverse yard environments, and operational maturity."

YMX's Autonomous Yard Operating System (YMX OS) combines yard management technology, fleet operations, performance management, and data insights to improve throughput, service levels, and consistency across complex distribution networks. Outrider extends YMX OS with self-driving yard trucks that automate trailer and container movements. Initial deployments will target customers in food and beverage, retail, consumer packaged goods, and automotive starting this year.

Outrider has developed a purpose-built physical AI system for logistics yards that automates key aspects of the trailer spotting workflow. Its self-driving yard trucks navigate mixed-traffic yards, locate and move trailers, hitch and unhitch, precisely position trailers at dock doors and parking spots, and use a robotic system to connect and disconnect trailer brake lines. The technology also provides real-time trailer inventory tracking with no additional infrastructure, monitors EV charge status, and integrates with existing yard, warehouse, and transportation management systems.

This agreement extends the leadership of both companies in the electrification space. YMX offers capacity-based pricing rather than hourly rates, so customers can maximize the use of EV yard technology in their distribution and manufacturing hubs. Outrider designed its autonomous system from the outset for electric yard truck platforms, giving customers a simple path to achieve the benefits of both automation and electrification. This combined offering is increasingly valuable as diesel costs rise, with U.S. on-highway diesel averaging $6.38 per gallon the week of Sept. 28, 2026.

Under the agreement, YMX will lead customer implementations, finance and operate the self-driving fleets, and provide on-site support. Outrider will support deployments and provide ongoing remote monitoring and technical support. The companies will jointly support site planning, deployment execution, and operating processes to continuously improve throughput, safety, and sustainability while simplifying the operational and change management required to advance yard automation.

"Large shippers are focused on running complex operations and often lack the time and resources to evaluate, deploy, and support new technologies themselves. At the same time, supply chain executives and site personnel are eager for safer, more productive yards," said Andrew Smith, CEO of Outrider. "YMX has built an exceptional business around delivering turnkey, integrated technology and operating services to enterprise customers. The YMX and Outrider partnership gives enterprise shippers a simple path to deploy and scale physical AI across their yard operations."

System safety was a key factor in YMX's selection of Outrider. Outrider developed the industry's first safety system purpose-built for scalable driverless operations in mixed-traffic logistics yards, where self-driving yard trucks maneuver semi-trailers alongside personnel and manually driven vehicles. TÜV SÜD, a globally recognized independent testing and certification organization, determined that Outrider's functional safety approach aligns with its Autonomous Vehicle Conformity Framework requirements.

First Quarter 2026 Operating Results

The following table provides a summary of the Fund's operating results for the first quarter of 2026:

The $0.9 million increase in total investment income in the first quarter of 2026 from the comparable period of the prior year was principally attributable to (i) a $2.0 million increase in interest income, primarily due to higher average levels of income producing investment portfolio debt investments, partially offset by a decrease in interest rates, primarily resulting from decreases in benchmark index rates on floating rate investment portfolio debt investments, and (ii) a $0.5 million increase in fee income, primarily due to an increase in fee income related to increased investment activity. These increases were partially offset by a $1.6 million decrease in dividend income, primarily due to a $1.5 million decrease in dividend income from the Fund's LMM portfolio companies. The $0.9 million increase in total investment income in the first quarter of 2026 is after the impact of a decrease of $0.2 million in certain income considered less consistent or non-recurring, primarily related to decreases of (i) $0.2 million in such dividend income and (ii) $0.2 million in such interest income from accelerated prepayment, repricing and other activity related to certain investment portfolio debt investments, partially offset by a $0.2 million increase in such fee income, in each case when compared to the same period in 2025.

Total expenses, net of waivers, increased by $0.4 million, or 2.5%, to $16.8 million in the first quarter of 2026 from $16.4 million for the same period in 2025. This increase was principally attributable to (i) a $0.7 million increase in interest expense, (ii) a $0.3 million increase in base management fees and (iii) a $0.1 million increase in incentive fee on income, net of waivers, partially offset by a $0.6 million decrease in the ending accrual for the accrued capital gains incentive fee(3) as of March 31, 2026. The increase in interest expense is primarily related to an increase in average borrowings outstanding used to fund a portion of the growth of the Fund's investment portfolio, partially offset by decreased weighted-average interest rates on the Credit Facilities due to decreases in benchmark floating index interest rates and a decrease in the applicable interest rate spread on the SPV Facility resulting from the amendment of the SPV Facility in March 2025 (with the Credit Facilities and the SPV Facility each defined in the Liquidity and Capital Resources section below). The increase in base management fees is primarily the result of the Fund's increased average total assets, partially offset by the benefit of the lower base management fee percentage for the full quarter in the first quarter of 2026 compared to the benefit for a partial quarter in the first quarter of 2025 as a result of the Fund's entry into an amended advisory agreement (the "Amended Advisory Agreement") with the Adviser (defined below), effective upon the listing of the Fund's common stock on the New York Stock Exchange on January 29, 2025 (the "MSC Income Listing"). The increase in incentive fee on income, net of waivers, is the result of (a) an increase in the gross calculated incentive fee on income of $1.1 million, partially offset by (b) a $1.0 million voluntary waiver of incentive fee on income by the Adviser. The increase in the gross calculated incentive fee on income is a result of the Amended Advisory Agreement. The reduction in the capital gains incentive fee accrual(3) is due to the net fair value depreciation of the Fund's investments in the first quarter of 2026.

The Fund's ratio of total non-interest operating expenses, excluding incentive fees, net of waivers, as a percentage of quarterly average total assets, or the Operating Expenses to Assets Ratio, decreased to 1.8% on an annualized basis for the first quarter of 2026, from 1.9% for the first quarter of 2025, primarily due to the benefit of the lower base management fee percentage in the first quarter of 2026 as discussed above.

The $0.5 million increase in NII in the first quarter of 2026 from the comparable period of the prior year was principally attributable to an increase in total investment income, partially offset by an increase in total expenses, net of waivers, each as discussed above. NII on a per share basis was $0.35 per share for the first quarter of 2026, consistent with the first quarter of 2025.

The $0.1 million, or $0.01 per share, decrease in ANII(1) in the first quarter of 2026 to $15.6 million, or $0.34 per share, from $15.7 million, or $0.35 per share, in the first quarter of 2025 was principally attributable to the same factors noted above for the change in NII, but excluding the impact of the $0.6 million decrease in the capital gains incentive fee accrual.

The per share changes in NII and ANII(1) in the first quarter of 2026 from the comparable period of the prior year include the impact of a 3.2% increase in the weighted-average shares outstanding, primarily due to shares issued in connection with the MSC Income Listing and shares issued through the dividend reinvestment plan, partially offset by shares repurchased by the Fund, in each case since the beginning of the comparable period of the prior year. NII and ANII(1) on a per share basis in the first quarter of 2026 each include a decrease of $0.01 per share resulting from a decrease in investment income considered less consistent or non-recurring in nature compared to the first quarter of 2025, as discussed above.

The $13.2 million net increase in net assets resulting from operations in the first quarter of 2026 represents a $2.7 million decrease from the first quarter of 2025. This decrease was primarily the result of (i) a $2.5 million increase in net tax provision on the net fair value change of the portfolio investments resulting from a net tax provision of $0.1 million in the first quarter of 2026 compared to a net tax benefit of $2.4 million in the comparable period of the prior year and (ii) a $0.6 million decrease in the net fair value change of the Fund's portfolio investments resulting from the net impact of net realized gains/losses and net unrealized appreciation/depreciation, with the decrease resulting from a net fair value decrease of $2.9 million in the first quarter of 2026 compared to a net fair value decrease of $2.3 million in the comparable period of the prior year, partially offset by a $0.5 million increase in NII as discussed above. The $2.9 million net fair value decrease in the first quarter of 2026 was the result of a net realized loss of $0.

MSC Income Fund Announces Exit of Portfolio Investment

Generates $11.6 Million Realized Gain from Exit of Equity Investment in Centre Technologies Holdings, LLC

HOUSTON, June 24, 2026 /PRNewswire/ -- MSC Income Fund, Inc. (NYSE: MSIF) ("MSC Income" or the "Fund") is pleased to announce that it recently exited its debt investments and equity investment in Centre Technologies Holdings, LLC ("Centre" or the "Company") upon the completion of a majority recapitalization with a new financial sponsor. Founded in 2006 and headquartered in Houston, Texas, Centre is a provider of information technology (IT) services, including managed services, cloud solutions, cyber security, IT consulting and business intelligence (BI) services to lower and middle market businesses, often serving as a fully outsourced IT department.

The Fund partnered with Centre's existing owners and senior management team and Main Street Capital Corporation (NYSE: MAIN) ("Main Street") in January 2019 to facilitate a minority recapitalization of the Company and provide growth capital to help facilitate the Company's acquisition growth strategy. The Fund's initial investment consisted of a $0.6 million revolving line of credit, a $3.1 million first lien, senior secured term loan and a $1.5 million direct equity investment. After the Fund's initial investment, Centre completed seven follow-on acquisitions with MSC Income funding an additional cumulative $6.9 million under the first lien, senior secured term loan facility and $0.1 million in direct equity investments to support the Company's acquisition strategy and other corporate activities, resulting in the Fund's total debt investments and total equity investments growing to $10.6 million and $1.6 million, respectively.

The Fund realized a gain of $11.6 million on the exit of its equity investment in Centre, including a minority equity ownership position in Centre's acquirer that the Fund received as part of the sale proceeds, with this realized value representing an increase of $1.7 million above the Fund's fair market value for this equity investment as of March 31, 2026. The Fund also received total dividends of $0.5 million over the life of its equity investment in the Company. As a result, on a cumulative basis since the Fund's initial investment in January 2019 and taking the realized gain, dividends and fees into consideration, the Fund realized an annual internal rate of return ("IRR") of 40.1% and an 8.8 times money invested ("TMI") return on its equity investment in Centre. On a cumulative basis including both the Fund's debt and equity investments in the Company, the Fund realized an IRR of 23.2% and a 2.4 TMI return.

Based upon the quality of the Fund's existing investment portfolio, together with the favorable liquidity position and the current investment pipeline, we remain excited about our future expectations for the Fund."

Second Quarter 2026 Operating Results

The following table provides a summary of the Fund's operating results for the second quarter of 2026:

The $0.1 million increase in total investment income in the second quarter of 2026 from the comparable period of the prior year was principally attributable to (i) a $0.7 million increase in interest income, primarily due to higher average levels of income producing investment portfolio debt investments, partially offset by a decrease in interest rates, primarily resulting from decreases in benchmark index rates on floating rate investment portfolio debt investments, and the negative impact from investment portfolio debt investments on non-accrual status and (ii) a $0.5 million increase in fee income, primarily due to an increase in fee income from the refinancing and prepayment of investment portfolio debt investments. These increases were partially offset by a $1.1 million decrease in dividend income, primarily due to a $0.9 million decrease in dividend income from the Fund's LMM portfolio companies. The $0.1 million increase in total investment income in the second quarter of 2026 includes the impact of an increase of $1.4 million in certain income considered less consistent or non-recurring, primarily related to increases of (i) $0.7 million in such fee income and (ii) $0.5 million in such dividend income, in each case when compared to the same period in 2025.

Total expenses, net of waivers, increased by $4.0 million, or 21.8%, to $22.3 million in the second quarter of 2026 from $18.3 million for the same period in 2025. This increase was principally attributable to (i) a $2.9 million increase in the ending accrual for the accrued capital gains incentive fee(3) as of June 30, 2026, (ii) a $1.2 million increase in interest expense and (iii) a $0.4 million increase in base management fees, partially offset by a $0.6 million decrease in incentive fee on income, net of waivers. The increase in the capital gains incentive fee accrual(3) was due to the net fair value appreciation of the Fund's investments in the second quarter of 2026. The increase in interest expense was primarily related to (i) an increase in average borrowings outstanding used to fund a portion of the growth of the Fund's investment portfolio and (ii) an increased weighted-average interest rate on the Fund's unsecured debt obligations, driven by the issuance of the May 2029 Notes in the first quarter of 2026, partially offset by a decreased weighted-average interest rate on the Credit Facilities due to decreases in benchmark floating index interest rates (with the May 2029 Notes and the Credit Facilities each defined in the Liquidity and Capital Resources section below). The increase in base management fees was primarily the result of the Fund's increased average total assets. The decrease in incentive fee on income, net of waivers, was the result of (a) a decrease in the gross calculated incentive fee on income of $0.3 million, primarily driven by a decrease in pre-incentive NII, and (b) a $0.3 million voluntary waiver of incentive fee on income by the Adviser (defined below).

The Fund's ratio of total non-interest operating expenses, excluding incentive fees, net of waivers, as a percentage of quarterly average total assets, or the Operating Expenses to Assets Ratio, was 1.9% on an annualized basis for the second quarter of 2026, consistent with the second quarter of 2025.

The $4.3 million decrease in NII in the second quarter of 2026 from the comparable period of the prior year was principally attributable to an increase in total expenses, net of waivers, partially offset by an increase in total investment income, each as discussed above. NII on a per share basis decreased by $0.09 per share for the second quarter of 2026 as compared to the second quarter of 2025, to $0.26 per share, reflecting the impact of the $0.07 per share capital gains incentive fee accrual(3) in the second quarter of 2026.

The $1.4 million, or $0.02 per share, decrease in ANII(1) in the second quarter of 2026 to $14.9 million, or $0.33 per share, from $16.3 million, or $0.35 per share, in the second quarter of 2025 was principally attributable to the same factors noted above for the change in NII, but excluding the impact of the $2.9 million increase in the capital gains incentive fee accrual.(3)

The per share changes in NII and ANII(1) in the second quarter of 2026 from the comparable period of the prior year include the impact of a 3.6% decrease in the weighted-average shares outstanding, primarily due to shares repurchased by the Fund, partially offset by shares issued through the dividend reinvestment plan, in each case since the beginning of the comparable period of the prior year. NII and ANII(1) on a per share basis in the second quarter of 2026 each include an increase of $0.03 per share resulting from an increase in investment income considered less consistent or non-recurring in nature compared to the second quarter of 2025, as discussed above.

The $29.3 million net increase in net assets resulting from operations in the second quarter of 2026 represents a $13.0 million increase from the second quarter of 2025. This increase was primarily the result of an $18.1 million increase in the net fair value change of the Fund's portfolio investments resulting from the net impact of net realized gains/losses and net unrealized appreciation/depreciation, with the increase resulting from a net fair value increase of $19.0 million in the second quarter of 2026 compared to a net fair value increase of $0.9 million in the comparable period of the prior year, partially offset by (i) a $4.3 million decrease in NII as discussed above and (ii) a $0.8 million increase in the net tax provision on the net fair value change of the portfolio investments, resulting from a net tax provision of $1.7 million in the second quarter of 2026 compared to a net tax provision of $0.9 million in the comparable period of the prior year. The $19.0 million net fair value increase in the second quarter of 2026 was the result of a net realized gain of $9.9 million and net unrealized appreciation (including the reversal of net fair value appreciation recognized in prior periods due to the net realized gain in the quarter) of $9.1 million. The $0.9 million net fair value increase in the second quarter of 2025 was the result of a net realized gain of $4.8 million, partially offset by net unrealized depreciation of $3.9 million. The $9.9 million net realized gain from investments for the second quarter of 2026 was primarily the result of an $11.6 million realized gain on the full exit of a LMM portfolio investment, partially offset by a $1.
