STRATEGY

To drive the creation of long-term sustainable shareholder value, the Company employs a three-part value creation strategy: Build, Grow and Expand.

1

Build: To build on the Company’s foundation and drive performance improvements, management is focused on the advancement of the ATS Business Model (“ABM”), the pursuit and measurement of value drivers and key performance indicators, a rigorous strategic planning process, succession planning, talent management, employee engagement, and instilling autonomy with accountability into its businesses.

Grow: To drive organic growth, ATS develops and implements growth tools under the ABM, provides innovation and value to customers and works to grow reoccurring revenues.

Expand: To expand the Company’s reach, management is focused on the development of new markets and business platforms, the expansion of service offerings, investment in innovation and product development, and strategic and disciplined acquisitions that strengthen ATS.

The Company pursues all of its initiatives using a strategic capital allocation framework in order to drive the creation of long-term sustainable shareholder value.

ATS Business Model

The ABM is a business management system that ATS developed with the goal of enabling the Company to pursue its strategies, outpace the growth of its chosen markets, and drive continuous improvement year over year. The ABM emphasizes:

•People: developing, engaging and empowering ATS’ people to build the best team;

•Process: aligning ATS’ people to implement and continuously improve robust and disciplined business processes throughout the organization; and

•Performance: consistently measuring results in order to yield world-class performance for ATS' customers and shareholders.

The ABM is ATS’ playbook, serving as the framework to achieve business goals and objectives through disciplined, continuous improvement. The ABM is employed by ATS divisions globally and is supported with extensive training in the use of key problem-solving tools, and applied through various projects to drive continuous improvement. When ATS makes an acquisition, the ABM is quickly introduced to the new company as a means of supporting cultural and business integration.

1Non-IFRS Financial Measure - See “Non-IFRS and Other Financial Measures.”

2Certain Non-IFRS Financial Measures have been revised from previously disclosed values to exclude the impact on stock-based compensation expense of the revaluation of deferred stock units and restricted share units resulting specifically from the change in market price of the Company's common shares between periods. Management believes that this adjustment provides further insight into the Company's performance, as share price volatility drives variability in the Company's stock-based compensation expense.

EXECUTIVE SUMMARY: GROWTH IN STRATEGIC END MARKETS

•Growth in third quarter revenues of 16.2% year over year was driven by organic revenue growth of 9.1%, in addition to 2.5% from the positive impact of foreign exchange translation, and 4.6% from recently acquired companies. “Acquisitions” or “acquired companies” in this MD&A refer to companies that were not part of the consolidated group in the comparable prior-year periods. Organic revenue is a Non-IFRS Financial Measure and organic revenue growth is a Non-IFRS Ratio - see “Non-IFRS and Other Financial Measures”.

•Trailing twelve month book-to-bill ratio at December 31, 2023 was 0.95:1, with Order Bookings in the third quarter amounting to $668 million compared to $979 million a year earlier when ATS received Order Bookings of U.S. $221.3 million (approximately $300.2 million CAD) from an electric vehicle ("EV") customer. Organic Order Bookings were 36.2% lower than a year ago (which included these EV Order Bookings), partially offset by a 3.0% contribution from recent acquisitions and a positive impact of 1.4% from foreign exchange translation. Order Bookings, organic Order Bookings growth and book-to-bill ratio are Supplementary Financial Measures - see “Non-IFRS and Other Financial Measures”.

•Order Backlog of $1,907 million at quarter-end was 11.0% lower than the prior year, and is distributed across strategic global markets and regulated industries, and provides good revenue visibility. Order Backlog is a Supplementary Financial Measure - see “Non-IFRS and Other Financial Measures”.

•Non-cash working capital as a percentage of revenues was 17.8% and decreased in comparison to the prior quarter, primarily driven by customer project schedules, including timing of milestone billings and payments for large EV programs. Net debt to adjusted EBITDA ratio at December 31, 2023 of 2.3 times increased with the acquisition of Avidity (as defined herein) and

3

was within the Company's target range as it continues to fund short-term working capital requirements to support growth. Non-cash working capital as a percentage of revenues and net debt to adjusted EBITDA are Non-IFRS ratios — see “Non-IFRS and Other Financial Measures”.

•Adjusted earnings from operations for the third quarter increased 17.4% to $101.2 million (13.5% margin), compared to $86.2 million (13.3% margin) a year ago on higher revenues, partially offset by higher SG&A expenses. (Adjusted earnings from operations is a Non-IFRS Financial Measure and adjusted earnings from operations margin is a Non-IFRS Ratio — see “Non-IFRS and Other Financial Measures”.)

STRATEGIC BUSINESS ACQUISITIONS

On June 30, 2023, the Company acquired Yazzoom B.V. ("Yazzoom"), a Belgium-based provider of artificial intelligence and machine learning based tools for industrial production. Yazzoom joined ATS' Process Automation Solutions ("PA") business to broaden its process optimization and digitalization capabilities in key focus sectors. Yazzoom leverages integrated data to enable predictive analytics and insights that drive tangible improvements in production processes. The purchase price was $5.3 million (3.7 million Euros).

On July 3, 2023, the Company acquired Odyssey Validation Consultants Limited ("Odyssey"), an Ireland-based provider of digitalization solutions for the life sciences industry. Odyssey also joined ATS' PA business, and their expertise in delivering production process improvements through computer system validation as well as cloud-based software solutions are also expected to advance PA's digitalization capabilities. The purchase price was $5.6 million (3.9 million Euros).

On November 16, 2023, the Company acquired Avidity Science, LLC ("Avidity"), a growing designer and manufacturer of automated water purification solutions for biomedical and life science applications. The total purchase price paid in the third quarter of fiscal 2024, pending post-closing adjustments was $271.9 million (U.S. $198.6 million). Avidity serves a diverse global customer base of pharmaceutical, biopharma, healthcare, government, and academic research facilities. Avidity bolsters ATS' value proposition for both new and existing customers by providing researchers confidence in their data during key stages of drug discovery, development and testing.

On January 1, 2024, subsequent to the third quarter, the Company acquired IT.ACA. Engineering S.r.l., an Italian automation system integrator.

Order Bookings by Quarter

Third quarter fiscal 2024 Order Bookings were $668 million, a 31.8% year over year decrease, reflecting an organic Order Bookings decline of 36.2%, primarily related to the transportation market, partially offset by 3.0% growth from acquired companies, in addition to a 1.4% increase due to foreign exchange rate translation of Order Bookings from foreign-based ATS subsidiaries, primarily reflecting the strengthening of the Euro relative to the Canadian dollar. Order Bookings from acquired companies totalled $29.0 million. By market, Order Bookings in life sciences increased compared to the prior-year period primarily due to $18.1 million of contributions from acquired companies, organic growth and a positive foreign exchange rate translation of Order Bookings from foreign-based ATS subsidiaries. Order Bookings in transportation decreased compared to the prior-year period, as a result of variability on timing of large EV orders. Third quarter fiscal 2023 included Order Bookings of U.S. $221.3 million (approximately $300.2 million CAD) from a global automotive customer to move towards fully automated battery assembly systems for their North American manufacturing operations. Order Bookings in food & beverage increased compared to the prior-year period primarily due to foreign exchange rate translation of Order Bookings from foreign-based ATS subsidiaries. Order Bookings in

4

consumer products increased primarily due to the timing of customer projects and contributions from acquired companies. Order Bookings in energy decreased primarily due to timing of customer projects.

Trailing twelve month book-to-bill ratio at December 31, 2023 was 0.95:1. Book-to-bill ratio is a supplementary financial measure - see “Non-IFRS and Other Financial Measures.”

At December 31, 2023, Order Backlog was $1,907 million, 11.0% lower than at January 1, 2023 primarily on account of lower Order Backlog within the transportation market where several large, strategic Order Bookings were included a year ago.

The life sciences funnel remains strong, with a focus on strategic submarkets of pharmaceuticals, radiopharmaceuticals, and medical devices such as auto-fillers and auto-injectors. Management continues to see opportunities with both new and existing customers, including those customers using auto-injectors for diabetes and obesity treatments, and producers of contact lens and pre-filled syringes, as well as opportunities to provide life science solutions that leverage various integrated capabilities to serve broader customer needs. In transportation, the funnel largely includes strategic opportunities related to electric vehicles, as the global automotive industry continues to shift towards EV production. The strategic nature of EV programs can result in larger average order values, resulting in variability in Order Bookings. Management believes the Company's automated EV battery pack and assembly capabilities position ATS well within the industry. Management is working with one of its EV customers to support their revised timing on a portion of an existing program as the customer works to realign their production schedules. The near-term market for electric vehicles remains dynamic as automotive Original Equipment Manufacturers look to align capacity to end-market demand and lower platform costs, however the longer-term fundamentals remain intact and the transportation funnel is

5

strong and reflects diversified, long-term opportunities. Funnel activity in food & beverage remains strong, particularly for energy-efficient solutions. The Company continues to benefit from strong brand recognition within the global tomato processing industry, and there is ongoing interest in automated solutions with the food & beverage market. Funnel activity in consumer products is stable; inflationary pressures continue to have an effect on discretionary spending, which may impact timing of some customer investments. Funnel activity in energy remains strong and includes some longer-term opportunities in the nuclear industry. The Company is focused on clean energy applications including solutions for the refurbishment of nuclear power plants, early participation in the small modular reactor market, and grid battery storage. Across all markets, customers are exercising normal caution in their approach to investment and spending. Funnel growth in markets where environmental, social and governance ("ESG") requirements are an increasing focus for customers — including grid battery storage, EV and nuclear, as well as consumer goods packaging — provide ATS with opportunities to use its capabilities to respond to customer sustainability standards and goals, including global and regional requirements to reduce carbon emissions. Customers seeking to de-risk or enhance the resiliency of their supply chains, address a shortage of skilled workers or combat higher labour costs also provide future opportunities for ATS to pursue. Management believes that the underlying trends driving customer demand for ATS solutions including rising labour costs, labour shortages, production onshoring or reshoring and the need for scalable, high-quality, energy-efficient production remain favourable.

Order Backlog of $1,907 million is expected to help mitigate some of the impact of quarterly variability in Order Bookings on revenues in the short term. The Company’s Order Backlog includes several large enterprise programs that have longer periods of performance and therefore longer revenue recognition cycles. These programs have extended the average period over which the Company expects to convert its Order Backlog to revenues, providing ATS with longer visibility. In the fourth quarter of fiscal 2024, management expects the conversion of Order Backlog to revenues to be in the 36% to 39%range. This estimate is calculated each quarter based on management’s assessment of project schedules across all customer contracts, expectations for faster-turn product and services revenues, expected delivery timing of third-party equipment and operational capacity. The fourth-quarter conversion range accounts for the impact of approximately $200 million of Order Backlog with one of the Company's EV customers that has been delayed, as noted above. Management expects that the program will restart in the first quarter of fiscal 2025.

The timing of customer decisions on larger opportunities is expected to cause variability in Order Bookings from quarter to quarter. Revenues in a given period are dependent on a combination of the volume of outstanding projects the Company is contracted to, the size and duration of those projects, and the timing of project activities including design, assembly, testing, and installation. Given the specialized nature of the Company’s offerings, the size and scope of projects vary based on customer needs. The Company seeks to achieve revenue growth organically and by identifying strategic acquisition opportunities that provide access to attractive end-markets and new products and technologies and deliver hurdle-rate returns.

In the short term, ATS will continue to mitigate supply chain volatility, which has been contributing to longer lead times and cost increases in the supply base over the past several quarters. However, prolonged cost increases and price volatility have and may continue to disrupt the timing and progress of the Company’s margin expansion efforts and affect revenue recognition. In addition, with a portion of Order Backlog related to one of the Company's EV programs currently delayed, Management expects to see near-term margin pressure in its Transportation business. Over time, sustaining management's margin target assumes that the Company will successfully implement the initiatives noted below, and that such initiatives will result in improvements to its adjusted earnings from operations margin that

6

offset these shorter-term pressures (see “Forward-Looking Statements” for a description of the risks underlying the achievement of the margin target in future periods).

The Company regularly monitors customers for changes in credit risk and does not believe that any single industry or geographic region represents significant credit risk.

In the short term, the Company expects non-cash working capital to remain elevated as large enterprise programs progress through milestones. Over the long-term, the Company expects to continue investing in non-cash working capital to support growth, with fluctuations expected on a quarter-over-quarter basis. The Company’s long-term goal is to maintain its investment in non-cash working capital as a percentage of annualized revenues below 15%. However, given the size and timing of milestone payments for certain large EV programs in Order Backlog, the Company could see its working capital exceed 15% of annualized revenues in certain periods as it did in the first three quarters of fiscal 2024. The Company expects that continued cash flows from operations, together with cash and cash equivalents on hand and credit available under operating and long-term credit facilities will be sufficient to fund its requirements for investments in non-cash working capital and capital assets, and to fund strategic investment plans including some potential acquisitions. Acquisitions could result in additional debt or equity financing requirements for the Company. Non-cash working capital as a percentage of revenues is a Non-IFRS ratio - see “Non-IFRS and Other Financial Measures.”

Management is pursuing several initiatives to grow revenues and improve profitability with the goal of expanding its adjusted earnings from operations margin to 15% over time through a combination of operational initiatives and portfolio development. Operational initiatives include a focus on pursuing continuous improvement in all business activities through the ABM, including in acquired businesses, improving global supply chain management, increasing the use of standardized platforms and technologies, and growing revenues while leveraging the Company’s cost structure. Portfolio development initiatives include efforts to grow the Company's products and after-sales service revenues as a percentage of overall revenues. After-sales revenues and reoccurring revenues, which ATS defines as revenues from ancillary products and services associated with equipment sales, and revenues from customers who purchase non-customized ATS product at regular intervals, are expected to provide some balance to customers' capital expenditure cycles. Management estimates that reoccurring revenues are currently in the range of 25% to 35% of total revenues on a trailing twelve-month basis. Moreover, the Company's financial profile, which has included strong growth, margin expansion and disciplined working capital investment, has allowed it to generate free cash flows that are reinvested back into the business. Management also sees the development of the Company's digitalization capabilities as another key area of growth for the portfolio, including the collection and interpretation of data to drive meaningful change that optimizes performance for customers. In addition, management is focused on investing in innovation and employing a consistent, strategic approach to acquisitions. The Company continues to make progress in line with its plans to integrate acquired companies, and expects to realize cost and revenue synergies consistent with announced integration plans.

Reorganization Activity

The Company periodically undertakes reviews of its operations to ensure alignment with strategic market opportunities. As a part of this review, the Company has identified and previously announced an opportunity to improve the cost structure of the organization and reallocate investment to growth areas. In the third quarter of fiscal 2024, restructuring expenses of $16.2 million were recorded in relation to the reorganization. The majority of the remaining actions are expected to be completed during the fourth quarter of fiscal 2024. The total estimated cost of these activities is expected to be at the higher end of the previously disclosed range of $15 million to $20 million.

Fiscal 2024 third quarter revenues were 16.2% or $105.0 million higher than in the corresponding period a year ago. This performance reflected year-over-year organic revenue growth (growth excluding contributions from acquired companies and foreign exchange translation) of $59.2 million or 9.1%, and revenues earned by acquired companies of $29.7 million, most notably $13.8 million from Avidity, which was acquired in the third quarter of fiscal 2024. Foreign exchange translation positively impacted revenues by $16.1 million or 2.5%, primarily reflecting the strengthening of the Euro relative to the Canadian dollar. Revenues generated from construction contracts increased 14.9% or $63.0 million due to organic revenue growth combined with positive foreign exchange translation impact. Revenues from services increased 23.2% or $28.8 million due to revenues earned by acquired companies of $18.0 million in addition to organic revenue growth and the positive impact of foreign exchange translation. Revenues from the sale of goods increased 13.1% or $13.2 million primarily due to revenues earned by acquired companies of $11.2 million in addition to a positive foreign exchange translation impact.

By market, revenues generated in life sciences increased $12.7 million or 4.2% year over year. This was primarily due to contributions from acquisitions totalling $18.2 million and the positive impact of foreign exchange translation, partially offset by revenues earned a year ago on a large $120.0 million program. Revenues in transportation increased $78.8 million or 48.8%, due to timing of program execution and on higher Order Backlog entering the third quarter of fiscal 2024, driven primarily by EV Order Bookings, including previously announced EV Order Bookings of U.S. $578.2 million. Revenues generated in food & beverage increased $6.4 million or 7.2% due to revenues earned by acquired companies and the positive impact of foreign exchange translation. Revenues generated in consumer products decreased $0.9 million or 1.3%. Revenues in energy increased $8.0 million or 34.9% due to higher Order Backlog entering the period as compared to the prior year and $3.5 million of contributions from acquisitions.

Revenues for the nine months ended December 31, 2023 were 21.4% or $394.8 million higher than in the prior year and included $59.5 million of revenues earned by acquired companies, most notably $19.8 million from Zi-Argus Australia Pty Ltd. and Zi-Argus Ltd. ("ZIA"), $13.8 million from IPCOS, and $13.8 million from Avidity. Organic revenue growth, excluding contributions from acquired companies and the impact of foreign exchange fluctuations, was $249.9 million or 13.6% higher than the corresponding period in the prior year. Organic revenue growth was primarily related to activity in transportation, driven by EV work, as well as increases in food & beverage. Foreign exchange translation positively impacted revenues by $85.4 million or 4.6%, primarily reflecting the strengthening of the U.S. dollar and Euro relative to the Canadian dollar. Revenues generated from construction contracts increased 27.1% or $314.1 million due to organic revenue growth combined with positive foreign exchange translation impact. Revenues from services increased 25.2% or $89.5 million due to revenues earned by acquired companies of $47.2 million, most notably $19.8 million from ZIA and $13.8 million from IPCOS, in addition to organic revenue growth and the positive impact of foreign exchange translation. Revenues from the sale of goods decreased 2.7% or $8.8 million primarily due to lower Order Backlog entering the period compared to the prior year, partially offset by revenues earned by acquired companies of $11.2 million, most notably Avidity, and the positive impact of foreign exchange translation.

By market, for the nine months ended December 31, 2023, revenues from life sciences increased $7.9 million or 0.9% primarily revenues earned by acquired companies of $26.6 million and a positive impact of foreign exchange translation, partially offset by revenues earned a year ago on a large $120.0 million program. Revenues in transportation increased $332.1 million or 87.6% due primarily to revenues earned on previously announced large EV Order Bookings. Revenues generated in food & beverage increased $63.0 million or 23.1% due organic revenue growth and the positive impact of foreign

exchange translation. Revenues generated in consumer products decreased $5.7 million or 2.6%, due to lower Order Backlog entering the fiscal year, partially offset by contributions from acquired companies of $12.7 million. Revenues in energy decreased $2.5 million or 2.9% due to lower Order Backlog entering the fiscal year.

Cost of revenues. At $538.4 million, third quarter fiscal 2024 cost of revenues increased $75.1 million, or 16.2% compared to the corresponding period a year ago due primarily to higher revenues. Third quarter fiscal 2024 gross margin was 28.4%, compared to 28.4% in the corresponding period a year ago. Excluding acquisition-related inventory fair value charges of $0.8 million, gross margin in the third quarter of fiscal 2024 was 28.5%, 12 basis points higher than the prior year, primarily due to acquisitions partially offset by program mix. Year-to-date gross margin was 28.3% (28.4% excluding acquisition-related inventory fair value charges of $0.8 million) compared to 27.9% (or 28.4% excluding acquisition-related inventory fair value charges of $9.2 million) in the corresponding period a year ago. The year-to-date gross margin excluding acquisition-related inventory fair value charges remained flat, primarily due to acquisitions partially offset by program mix.

Selling, general and administrative (“SG&A”) expenses. SG&A expenses for the third quarter of fiscal 2024 were $114.2 million and included $17.1 million of costs related to the amortization of identifiable intangible assets on business acquisitions, $0.9 million of incremental costs related to the Company's acquisition activity, and an $11.7 million gain on sale of facilities. Excluding these items, SG&A expenses were $107.9 million in the third quarter of fiscal 2024. Comparably, SG&A expenses for the third quarter of fiscal 2023 were $93.2 million, which excluded $13.4 million of costs related to the amortization of identifiable intangible assets on business acquisitions, and $0.7 million of incremental costs related to the Company’s acquisition activity. Higher SG&A expenses in the third quarter of fiscal 2024 primarily reflected increased employee costs, the addition of SG&A expenses from acquired companies of $7.7 million and foreign exchange translation impact of $2.7 million.

For the nine months ended December 31, 2023, SG&A expenses were $359.8 million, which included $51.8 million of costs related to the amortization of identifiable intangible assets on business acquisitions, $2.1 million of incremental costs related to the Company’s acquisition activity, and an $11.7 million gain on sale of facilities. Excluding these costs, year-to-date SG&A expenses were $317.6 million. Comparably, SG&A expenses for the nine months ended January 1, 2023 were $269.6 million, which excluded $50.1 million of expenses related to the amortization of identifiable intangible assets on business acquisitions, and $1.6 million of incremental costs related to the Company’s acquisition activity. Excluding these costs, higher SG&A expenses for the nine months ended December 31, 2023 primarily reflected increased employee costs, $13.6 million of foreign exchange translation impact, and the addition of SG&A expenses from acquired companies of $17.4 million, most notably IPCOS and ZIA.

Stock-based compensation. Stock-based compensation expense was $4.7 million in the third quarter of fiscal 2024, which included $0.6 million recovery of revaluation expenses from deferred stock units and restricted share units resulting from the change in the market price of the Company's common shares between periods ("stock-based compensation revaluation expenses"). Comparably, stock-based compensation expense was $9.9 million in the corresponding period a year ago, which included $5.6 million of stock-based compensation revaluation expenses. For the nine months ended December 31, 2023, stock-based compensation expense was $18.1 million, which included $1.8 million of stock-based compensation revaluation expenses, compared to $11.3 million a year earlier, which included $1.7 million recovery of stock-based compensation expenses due to revaluation.

Fiscal 2024 third quarter earnings from operations were $78.5 million (10.4% operating margin) compared to $56.0 million (8.7% operating margin) in the third quarter a year ago. Fiscal 2024 third quarter earnings from operations included $0.8 million of acquisition-related fair value adjustments to acquired inventories recorded in cost of revenues, $17.1 million related to amortization of acquisition-related intangible assets, $0.9 million of incremental costs for the Company's acquisition activity, and an $11.7 million gain on sale of facilities recorded to SG&A expenses, $16.2 million of restructuring charges and a $0.6 million recovery of stock-based compensation expenses due to revaluation. Third quarter of fiscal 2023 earnings from operations included $13.4 million of amortization of acquisition-related intangible assets and $0.7 million of incremental costs for acquisition activity recorded in SG&A expenses, $10.5 million of restructuring charges, and $5.6 million of stock-based compensation revaluation expenses.

Excluding these items in both quarters, adjusted earnings from operations were $101.2 million (13.5% margin), compared to $86.2 million (13.3% margin) a year ago. Third quarter fiscal 2024 adjusted earnings from operations reflected higher revenues, partially offset by increased SG&A expenses.

For the nine months ended December 31, 2023, earnings from operations were $240.6 million (10.7% operating margin), compared to $170.6 million (9.2% operating margin) a year ago. Earnings from operations included $0.8 million of acquisition-related fair value adjustments to acquired inventories recorded in cost of revenues, $51.8 million related to amortization of acquisition-related intangible assets, $2.1 million of incremental costs related to the Company’s acquisition activity and a $11.7 million gain on sale of facilities recorded in SG&A expenses, $16.2 million of restructuring charges and $1.8 million of stock-based compensation revaluation expenses. For the nine months ended January 1, 2023, earnings from operations included $9.2 million of acquisition-related fair value adjustments to acquired inventories recorded in cost of revenues, $50.1 million related to amortization of acquisition-related intangible assets and $1.6 million of incremental costs related to the Company's acquisition activity recorded to SG&A, $11.7 million of restructuring charges and a $1.7 million recovery of stock-based compensation expenses due to revaluation.

Excluding those items in both years, adjusted earnings from operations were $301.6 million (13.5% margin), compared to $241.5 million (13.1% margin) in the corresponding period a year ago. Increased year-to-date adjusted earnings from operations reflected higher revenues, partially offset by increased SG&A expenses.

11

Net finance costs. Net finance costs were $17.5 million in the third quarter of fiscal 2024, compared to $19.7 million a year ago. The decrease was due to greater usage of the Company's credit facility to finance acquisitions a year ago. For the nine months ended December 31, 2023, finance costs were $49.9 million compared to $43.9 million a year ago. The increase was due to higher interest rates compared to a year ago.

Income tax provision. For the three- and nine-months ended December 31, 2023, the Company’s effective income tax rates of 22.6% and 23.6%, respectively, differed from the combined Canadian basic federal and provincial income tax rate of 26.5% due to income earned in certain jurisdictions with different statutory tax rates.

Net Income. Net income for the third quarter of fiscal 2024 was $47.2 million (48 cents per share basic), compared to $29.2 million (32 cents per share basic) for the third quarter of fiscal 2023. The increase primarily reflected higher revenues, partially offset by higher cost of revenues, SG&A, and restructuring charges. Adjusted basic earnings per share were 65 cents compared to 56 cents in the third quarter of fiscal 2023 (see “Reconciliation of Non-IFRS Measures to IFRS Measures”).

Net income for the nine months ended December 31, 2023 was $145.7 million ($1.49 per share basic), an increase of $47.6 million (and $0.42 per share basic) compared to a year ago. This was primarily the result of higher revenues, partially offset by higher cost of revenues, SG&A expenses, restructuring charges, income tax expense, stock-based compensation, and finance costs. Adjusted basic earnings per share were $1.96 for the nine months ended December 31, 2023 compared to $1.64 in the corresponding period a year ago (see “Reconciliation of Non-IFRS Measures to IFRS Measures”).

2The composition of these Non-IFRS Measures has been revised from what was previously disclosed. See "Non-IFRS and Other Financial Measures."

Depreciation and amortization expense was $35.2 million in the third quarter of fiscal 2024, compared to $27.9 million a year ago; the increase was primarily related to incremental depreciation and amortization expense from recently acquired companies.

EBITDA was $113.7 million (15.1% EBITDA margin) in the third quarter of fiscal 2024 compared to $83.9 million (13.0% EBITDA margin) in the third quarter of fiscal 2023. EBITDA for the third quarter of fiscal 2024 included $16.2 million of restructuring charges, $0.9 million of incremental costs related to acquisition activity, $0.8 million of acquisition-related fair value adjustments to acquired inventories, a $0.6 million recovery of stock-based compensation expenses due to revaluation, and an $11.7 million

12

gain on sale of facilities. EBITDA for the corresponding period in the prior year included $0.7 million of incremental costs related to acquisition activity, $10.5 million of restructuring charges, and $5.6 million of stock-based compensation revaluation expenses. Excluding these costs, adjusted EBITDA was $119.3 million (15.9% adjusted EBITDA margin), compared to $100.7 million (15.6% adjusted EBITDA margin) for the corresponding period in the prior year. Higher adjusted EBITDA reflected higher revenues partially offset by increased SG&A expenses. EBITDA is a non-IFRS measure - see “Non-IFRS and Other Financial Measures.”

Depreciation and amortization expense was $104.8 million for the first nine months of fiscal 2024, compared to $91.6 million a year ago; the increase was primarily related to incremental depreciation and amortization expense from recently acquired companies.

EBITDA was $345.4 million (15.4% EBITDA margin) in the first nine months of fiscal 2024 compared to $262.2 million (14.2% EBITDA margin) a year ago. EBITDA for the first nine months of fiscal 2024 included $16.2 million of restructuring charges, $2.1 million of incremental costs related to the Company’s acquisition activity, $0.8 million acquisition-related fair value adjustments to acquired inventories, $1.8 million of stock-based compensation revaluation expenses, and a $11.7 million gain on sale of facilities.

Excluding these costs in both years, adjusted EBITDA was $354.6 million (15.8% adjusted EBITDA margin), compared to $283.0 million (15.3% adjusted EBITDA margin) a year ago. Higher adjusted EBITDA reflected higher revenues partially offset by increased SG&A expenses.

SHARE DATA

During the first nine months of fiscal 2024, 89,773 stock options were exercised. At February 6, 2024 the total number of common shares outstanding was 98,929,461. There were also 865,386 stock options outstanding to acquire common shares of the Company and 629,558 RSUs outstanding that may be settled in ATS common shares purchased on the open market where deemed advisable by the Company, as an alternative to cash payments.

In fiscal 2023, a trust was created for the purpose of purchasing common shares of the Company on the stock market. The common shares are being held in trust and will be used to settle some or all of the fiscal 2023 and 2024 RSU grants when such RSU grants are fully vested. During the three months ended December 31, 2023, nil common shares were purchased, during the nine months ended December 31, 2023 the Company acquired 387,794 common shares for $23.8 million. The trust is included in the Company's interim condensed consolidated financial statements with the value of the acquired common shares presented as a reduction of share capital.

NORMAL COURSE ISSUER BID

On December 13, 2023, the Company announced that the TSX had accepted a notice filed by the Company of its intention to make a normal course issuer bid (“NCIB”). Under the NCIB, ATS may purchase for cancellation up to a maximum of 8,044,818 common shares during the 12-month period ending December 14, 2024.

For the nine months ended December 31, 2023, the Company purchased nil common shares under the recently announced and previous NCIB programs.

13

Some purchases under the NCIB may be made pursuant to an automatic share purchase plan between ATS and its broker. This plan enables the purchase of common shares when ATS would not ordinarily be active in the market due to internal trading blackout periods, insider trading rules, or otherwise. ATS security holders may obtain a copy of the notice, without charge, upon request from the Secretary of the Company. The NCIB program is viewed by the Company as one component of an overall capital structure strategy and complementary to its acquisition growth plans.

In the third quarter of fiscal 2024, cash flows provided by operating activities were $110.5 million compared to $116.1 million provided by operating activities in the corresponding period a year ago. The decrease primarily related to the timing of investments in non-cash working capital in certain customer programs.

In the nine months ended December 31, 2023, cash flows provided by operating activities were $11.2 million compared to $46.4 million provided by operating activities a year ago. The year-over-year decrease related primarily to the timing of investments in non-cash working capital in certain customer programs, primarily related to EV programs.

In the third quarter of fiscal 2024, the Company’s investment in non-cash working capital decreased $35.7 million from October 1, 2023. On a year-to-date basis, investment in non-cash working capital increased $236.0 million. Accounts receivable increased by 39.5%, or $157.7 million, while net contracts in progress increased 1.3%, or $3.0 million, compared to March 31, 2023, primarily due to the timing of billings in certain customer contracts and $18.0 million of accounts receivable from recent acquisitions. The Company actively manages its accounts receivable, contract asset and contract liability balances through billing terms on long-term contracts and collection efforts. Inventories increased 21.8%, or $55.9 million, to enable fulfillment of Order Backlog, in addition to $23.0 million of inventory from acquired entities. Deposits and prepaid assets increased 21.2% or $19.8 million compared to March 31, 2023 due to $3.2 million of contributions from acquired companies, higher investment tax credits, and an increase in the fair value of forward contacts. Accounts payable and accrued liabilities decreased 4.6% or $29.7 million compared to March 31, 2023 due to timing of supplier billings and payments partially offset by contributions from acquisitions of $27.2 million.

14

Provisions increased 19.6% or $6.0 million compared to March 31, 2023 due to costs accrued relating to the fiscal 2024 reorganization.

The free cash flow of the Company for the nine months ended December 31, 2023 was an outflow of $51.3 million, compared to an outflow of $0.4 million a year ago primarily due to increased investments in non-cash working capital and higher investments in property, plant and equipment. The Company has a multi-year free cash flow target of 100% of net income. Free cash flow is a non-IFRS financial measure - see “Non-IFRS and Other Financial Measures.”

Non-cash working capital as a percentage of revenue was 17.8% at December 31, 2023 compared to 10.1% at March 31, 2023.

Cash investments in property, plant and equipment totalled $46.5 million in the first nine months of fiscal 2024, primarily related to the expansion and improvement of certain manufacturing facilities. Intangible asset expenditures were $16.0 million in the first nine months of fiscal 2024, primarily related to computer software and various internal development projects.Capital expenditures for fiscal 2024 for tangible assets and intangible assets are expected to be in the lower end of the $80 million to $100 million range and reflect the plan to add capacity to support growth while continuing to invest in innovation. This spend is based on the needs of the business and timing of projects, and management continues to build flexibility into plans for the balance of the year.

At December 31, 2023, the Company had $383.5 million of unutilized multipurpose credit, including letters of credit, available under existing credit facilities and an additional $287.7 million available under letter of credit facilities.

On October 5, 2023, the Company amended its senior secured credit facility (the "Credit Facility") to extend the term loan maturity to match the maturity of the revolving line of credit. The Credit Facility consists of (i) a $750.0 million secured committed revolving line of credit and (ii) a fully drawn $300.0 million non-amortized secured term credit facility; both maturing on November 4, 2026. The Credit Facility is secured by the Company’s assets, including a pledge of shares of certain of the Company’s subsidiaries. Certain of the Company’s subsidiaries also provide guarantees under the Credit Facility. At December 31, 2023, the Company had utilized $763.0 million under the Credit Facility, of which $763.0 million was classified as long-term debt (March 31, 2023 - $691.9 million) and $0.0 million by way of letters of credit (March 31, 2023 - $0.0 million). During the nine months ended December 31, 2023, the Company drew $580.8 million and repaid $542.0 million on its Credit Facility, which included proceeds from the U.S. initial public offering.

The Credit Facility is available in Canadian dollars by way of prime rate advances and/or bankers’ acceptances, in U.S. dollars by way of base rate advances and/or Term SOFR, in Euros by way of EURIBOR advances, in British pounds sterling by way of Daily Simple SONIA advances, and by way of letters of credit for certain purposes. The interest rates applicable to the Credit Facility are determined based on a net debt-to-EBITDA ratio as defined in the Credit Facility. For prime rate advances and base rate advances, the interest rate is equal to the bank’s prime rate or the bank’s U.S. dollar base rate in Canada, respectively, plus a margin ranging from 0.45% to 2.00%. For bankers’ acceptances, Term SOFR, EURIBOR advances and Daily Simple SONIA advances, the interest rate is equal to the bankers’ acceptance fee, Term SOFR rate, EURIBOR rate or Daily Simple SONIA rate, respectively, plus a margin that varies from 1.45% to 3.00%. The Company pays a fee for usage of financial letters of credit that ranges from 1.45% to 3.00%, and a fee for usage of non-financial letters of credit that ranges from 0.97% to 2.00%. The Company pays a standby fee on the unadvanced portions of the amounts available for advance or drawdown under the Credit Facility at rates ranging from 0.29% to 0.60%. The Company's Credit Facility is subject to changes in market interest rates. Changes in economic

15

conditions outside of the Company's control could result in higher interest rates, thereby increasing its interest expense. The Company uses a variable for fixed interest rate swap to hedge a portion of its Credit Facility (see Risk Management).

The Credit Facility is subject to financial covenants including a net debt-to-EBITDA test and an interest coverage test. Under the terms of the Credit Facility, the Company is restricted from encumbering any assets with certain permitted exceptions. At December 31, 2023, all of the covenants were met.

The Company has additional credit facilities available of $104.2 million (40.8 million Euros, U.S.$24.0 million, 45.0 million Thai Baht, 5.0 million CNY, 5.0 million GBP, $0.2 million AUD and $1.5 million CAD). The total amount outstanding on these facilities as at December 31, 2023 was $7.6 million, of which $5.2 million was classified as bank indebtedness (March 31, 2023 - $5.8 million), $1.8 million was classified as long-term debt (March 31, 2023 - $0.2 million) and $0.6 million by way of letters of credit (March 31, 2023 - $0.2 million). The interest rates applicable to the credit facilities range from 0.03% to 8.45% per annum. A portion of the long-term debt is secured by certain assets of the Company.

The Company’s U.S. $350.0 million aggregate principal amount of senior notes (“the Senior Notes”) were issued at par, bear interest at a rate of 4.125% per annum and mature on December 15, 2028. After December 15, 2023, the Company may redeem the Senior Notes, in whole at any time or in part from time to time, at specified redemption prices and subject to certain conditions required by the Senior Notes. If the Company experiences a change of control, the Company may be required to repurchase the Senior Notes, in whole or in part, at a purchase price equal to 101% of the aggregate principal amount of the Senior Notes, plus accrued and unpaid interest, if any, to, but not including, the redemption date. The Senior Notes contain customary covenants that restrict, subject to certain exceptions and thresholds, some of the activities of the Company and its subsidiaries, including the Company’s ability to dispose of assets, incur additional debt, pay dividends, create liens, make investments, and engage in specified transactions with affiliates. At December 31, 2023, all of the covenants were met. Subject to certain exceptions, the Senior Notes are guaranteed by each of the subsidiaries of the Company that is a borrower or has guaranteed obligations under the Credit Facility. Transaction fees of $8.1 million were deferred and are being amortized over the term of the Senior Notes. The Company uses a cross-currency interest rate swap instrument to hedge a portion of its U.S.-dollar-denominated Senior Notes (see Risk Management).

Contractual Obligations

(In millions of dollars)

The Company’s contractual obligations are as follows as at December 31, 2023:

1Long-term debt obligations and lease liability obligations include principal and interest.

The Company’s off-balance sheet arrangements consist of purchase obligations, primarily commitments for material purchases, which have been entered into in the normal course of business.

16

In accordance with industry practice, the Company is liable to customers for obligations relating to contract completion and timely delivery. In the normal conduct of its operations, the Company may provide letters of credit as security for advances received from customers pending delivery and contract performance. In addition, the Company provides letters of credit for post-retirement obligations and may provide letters of credit as security on equipment under lease and on order. As at December 31, 2023, the total value of outstanding letters of credit was approximately $176.7 million (March 31, 2023 - $192.5 million).

In the normal course of operations, the Company is party to a number of lawsuits, claims and contingencies. Although it is possible that liabilities may be incurred in instances for which no accruals have been made, the Company does not believe that the ultimate outcome of these matters will have a material impact on its interim condensed consolidated statement of financial position.

The Company is exposed to credit risk on derivative financial instruments arising from the potential for counterparties to default on their contractual obligations to the Company. The Company minimizes this risk by limiting counterparties to major financial institutions and monitoring their credit worthiness. The Company’s credit exposure to forward foreign exchange contracts is the current replacement value of contracts that are in a gain position. The Company is also exposed to credit risk from its customers. Substantially all of the Company’s trade accounts receivable are due from customers in a variety of industries and, as such, are subject to normal credit risks from their respective industries. The Company regularly monitors customers for changes in credit risk. The Company does not believe that any single market or geographic region represents significant credit risk. Credit risk concentration, with respect to trade receivables, is mitigated as the Company primarily serves large, multinational customers and obtains receivables insurance in certain instances.

FINANCIAL INSTRUMENTS

The Company has various financial instruments including cash and cash equivalents, trade accounts receivable, bank indebtedness, trade accounts payable and accrued liabilities and long-term debt which are used in the normal course of business to maintain operations. The Company uses derivative financial instruments to help manage and mitigate various risks that the business faces.

An interest rate risk exists with financial instruments held by the Company, which is the risk that the fair value of future cash flows of a financial instrument will fluctuate as a result of changes in market interest rates. The Company manages interest rate risk on a portfolio basis and seeks financing terms in individual arrangements that are most advantageous taking into account all relevant factors.

The Company uses a variable for fixed interest rate swap as a derivative financial instrument to hedge a portion of its interest rate risk. Effective November 4, 2022, the Company entered into a variable for fixed interest rate swap instrument to swap the variable interest rate on its $300.0 million non-amortized secured credit facility to a fixed 4.241% interest rate. The terms of the hedging instrument will end on November 4, 2024. Effective November 21, 2023, the Company entered into a variable for fixed interest rate swap instrument to swap the variable interest rate on its $300.0 million non-amortized secured credit facility to a fixed 4.044% interest rate for the period November 4, 2024 to November 4, 2026.

A credit risk exists with financial instruments held by the Company, which is the risk of financial loss if a counterparty to a financial instrument fails to meet its contractual obligations. The Company attempts to mitigate this risk by following policies and procedures surrounding accepting work with

17

new customers, and performing work for a large variety of multinational customers in diversified industries.

There is a liquidity risk, which is the risk that the Company may encounter difficulties in meeting obligations associated with some financial instruments. This is managed by ensuring, to the extent possible, that the Company will have sufficient liquidity to meet its liabilities when they become due.

FOREIGN EXCHANGE RISK

The Company is exposed to foreign exchange risk as a result of transactions in currencies other than its functional currency of the Canadian dollar, through borrowings in currencies other than its functional currency and through its investments in its foreign-based subsidiaries.

The Company’s Canadian operations generate significant revenues in major foreign currencies, primarily U.S. dollars, which exceed the natural hedge provided by purchases of goods and services in those currencies. In order to manage a portion of this foreign currency exposure, the Company has entered into forward foreign exchange contracts. The timing and amount of these forward foreign exchange contract requirements are estimated based on existing customer contracts on hand or anticipated, current conditions in the Company’s markets and the Company’s past experience. Certain of the Company’s foreign subsidiaries will also enter forward foreign exchange contracts to hedge identified balance sheet, revenue and purchase exposures. The Company’s forward foreign exchange contract hedging program is intended to mitigate movements in currency rates primarily over a four- to six-month period.

The Company uses cross-currency swaps as derivative financial instruments to hedge a portion of its foreign exchange risk related to its U.S. dollar-denominated Senior Notes. On April 20, 2022, the Company entered into a cross-currency interest rate swap instrument to swap U.S. $175.0 million into Canadian dollars to hedge a portion of its foreign exchange risk related to its U.S. dollar-denominated Senior Notes. The Company will receive interest of 4.125% U.S. per annum and pay interest of 4.169% Canadian. The terms of the hedging instrument will end on December 15, 2025.

The Company manages foreign exchange risk on its Euro-denominated net investments. The Company uses a cross-currency interest rate swap as derivative financial instruments to hedge a portion of the foreign exchange risk related to its Euro-denominated net investment. On April 20, 2022, the Company entered into a cross-currency interest rate swap instrument to swap 161.1 million Euros into Canadian dollars. The Company will receive interest of 4.169% Canadian per annum and pay interest of 2.351% Euros. The terms of the hedging relationship will end on December 15, 2025.

In addition, from time to time, the Company may hedge the foreign exchange risk arising from foreign currency debt, intercompany loans, net investments in foreign-based subsidiaries and committed acquisitions through the use of forward foreign exchange contracts or other non-derivative financial instruments. The Company uses hedging as a risk management tool, not to speculate.

Interim financial results are not necessarily indicative of annual or longer-term results because capital equipment markets served by the Company tend to be cyclical in nature. Operating performance quarter to quarter is also affected by the timing of revenue recognition on large programs in Order Backlog, which is impacted by such factors as customer delivery schedules, the timing of receipt of third-party components, and by the timing of acquisitions. General economic trends, product life cycles and product changes may impact revenues and operating performance. ATS typically experiences some seasonality with its Order Bookings, revenues and earnings from operations, due to employee vacations, seasonality of growing seasons within the food industry and summer plant shutdowns by its customers.

RELATED PARTY TRANSACTIONS

The Company has an agreement with a shareholder, Mason Capital Management, LLC (“Mason Capital”), pursuant to which Mason Capital has agreed to provide ATS with ongoing strategic and capital markets advisory services for an annual fee of U.S. $0.5 million. As part of the agreement, Michael Martino, a member of the Company’s Board of Directors who is associated with Mason Capital, has waived any fees to which he may have otherwise been entitled for serving as a member of the Board of Directors or as a member of any committee of the Board of Directors.

There were no other significant related party transactions in the first nine months of fiscal 2024.

CRITICAL ACCOUNTING ESTIMATES AND ASSUMPTIONS

The preparation of the Company’s interim condensed consolidated financial statements requires management to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the end of the reporting period. Uncertainty about these estimates, judgments and assumptions could result in outcomes that require a material adjustment to the carrying amount of the asset or liability affected in future periods.

The Company based its assumptions on information available when the interim condensed consolidated financial statements were prepared. Existing circumstances and assumptions about future developments may change due to market changes or circumstances arising beyond the control of the Company. Such changes are reflected in the estimates as they occur.

There have been no material changes to the critical accounting estimates described in the Company’s fiscal 2023 MD&A.

23

Macroeconomic environment

The Company continues to operate amidst an uncertain macroeconomic environment, including inflation, supply chain disruptions, interest rate changes, regional conflicts, and the impacts of any pandemic or epidemic outbreak or resurgence. Further increases in inflation and interest rates could affect the global and Canadian economies, which could adversely affect the Company’s business, operations and customers. ATS will continue to monitor these dynamic macroeconomic conditions to assess any potential impacts on the business, financial results, and conditions of the Company. Management will continue to monitor and assess the impact of these factors on its judgments, estimates, accounting policies, and amounts recognized in the Company's interim condensed consolidated financial statements.

CONTROLS AND PROCEDURES

The Chief Executive Officer (“CEO”) and the Chief Financial Officer (“CFO”) of the Company are responsible for establishing and maintaining disclosure controls and procedures and internal controls over financial reporting for the Company. The control framework used in the design of disclosure controls and procedures and internal control over financial reporting is the “Internal Control – Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”).

There were no significant changes or material weaknesses in the design of the Company’s internal controls over financial reporting during the third quarter of fiscal 2024 that have materially affected, or are reasonably likely to materially affect, internal control over financial reporting.

Management, including the CEO and CFO, do not expect that the Company’s disclosure controls or internal controls over financial reporting will prevent or detect all errors and all fraud or will be effective under all potential future conditions. A control system is subject to inherent limitations and, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met.

24

Limitation on Scope

Avidity was acquired on November 16, 2023. The Avidity earnings were consolidated from November 16, 2023. Management has not fully completed its review of internal controls over financial reporting for this newly acquired organization. Since the acquisition occurred within the 365 days of the reporting period, management has limited the scope of design and subsequent evaluation of disclosure controls and procedures and internal controls over financial reporting, as permitted pursuant to National Instrument 52-109 - Certification of Disclosure in Issuer’s Annual and Interim Filings. For the period covered by this MD&A, management has undertaken additional procedures to satisfy itself with respect to the accuracy and completeness of the acquired company's financial information. The following summary of financial information pertains to the acquisition that was included in ATS’ interim condensed consolidated financial statements for the quarter ended December 31, 2023.

(millions of dollars)
Revenue1	$13.8 million
Net income1,3	$0.5 million
Current assets2	$51.9 million
Non-current assets2	$271.2 million
Current liabilities2	$23.3 million
Non-current liabilities2	$36.7 million

1 Results from November 16, 2023 to December 31, 2023

2 Balance sheet as at December 31, 2023

3 Net income includes items excluded from management's internal analysis of results, such as amortization expense of acquisition-related intangible assets, acquisition-related fair value adjustments to acquired inventories, finance costs, and certain other adjustments.

FORWARD-LOOKING STATEMENTS

This MD&A contains certain statements that may constitute forward-looking information and forward-looking statements within the meaning of applicable Canadian and United States securities laws ("forward-looking statements"). All such statements are made pursuant to the “safe harbour” provisions of Canadian provincial and territorial securities laws and the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements include all statements that are not historical facts regarding possible events, conditions or results of operations that ATS believes, expects or anticipates will or may occur in the future, including, but not limited to: the value creation strategy; the Company’s strategy to expand organically and through acquisition, and the expected benefits to be derived; the ABM; disciplined acquisitions; various market opportunities for ATS; expanding in emerging markets; the Company’s Order Backlog partially mitigating the impact of variable Order Bookings; rate of Order Backlog conversion to revenue; the potential impact of timing of customer decisions on Order Bookings, performance period, and timing of revenue recognition; the announcement of new Order Bookings and the anticipated timeline for delivery; potential impacts on the time to convert opportunities into Order Bookings; expected benefits with respect to the Company’s efforts to grow its product portfolio and after-sale service revenues; Company’s goal of expanding its adjusted earnings from operations margin over the long term and potential impact of supply chain disruptions; the ability of after-sales revenues and reoccurring revenues to provide some balance to customers’ capital expenditure cycles; the range of reoccurring revenues as a percentage of total revenues; the impact of developing the Company’s digitalization capabilities, including the collection and interpretation of data, as a key area of growth, and to drive meaningful change to optimize performance for customers; expectation of synergies from integration of acquired companies; non-cash working capital levels as a percentage of revenues in the short-term and the long-term; reorganization activity, and its ability to improve the cost structure of the Company, and to be reallocated to growth areas, and the expected timing and cost of this reorganization activity; expectations in relation to meeting liquidity and funding requirements for investments; potential to use debt or equity financing to support strategic

NON-IFRS AND OTHER FINANCIAL MEASURES

Throughout this document, management uses certain non-IFRS financial measures, non-IFRS ratios and supplementary financial measures to evaluate the performance of the Company.

The terms “EBITDA”, "organic revenue", “adjusted net income”, “adjusted earnings from operations”, “adjusted EBITDA”, “adjusted basic earnings per share”, and “free cash flow”, are non-IFRS financial measures, “EBITDA margin”, “adjusted earnings from operations margin”, “adjusted EBITDA margin”, "organic revenue growth", “non-cash working capital as a percentage of revenues”, and “net debt to adjusted EBITDA” are non-IFRS ratios, and "operating margin", “Order Bookings”, "organic Order Bookings", "organic Order Bookings growth", “Order Backlog”, and “book-to-bill ratio” are supplementary financial measures, all of which do not have any standardized meaning prescribed within IFRS and therefore may not be comparable to similar measures presented by other companies. Such measures should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. In addition, management uses “earnings from operations”, which is an additional IFRS measure, to evaluate the performance of the Company. Earnings from operations is presented on

27

the Company’s consolidated statements of income as net income excluding income tax expense and net finance costs. Operating margin is an expression of the Company’s earnings from operations as a percentage of revenues. EBITDA is defined as earnings from operations excluding depreciation and amortization. EBITDA margin is an expression of the Company’s EBITDA as a percentage of revenues. Organic revenue is defined as revenues in the stated period excluding revenues from acquired companies for which the acquired company was not a part of the consolidated group in the comparable period. Organic revenue growth compares the stated period organic revenue with the reported revenue of the comparable prior period. Adjusted earnings from operations is defined as earnings from operations before items excluded from management’s internal analysis of operating results, such as amortization expense of acquisition-related intangible assets, acquisition-related transaction and integration costs, restructuring charges, the mark-to-market adjustment on stock-based compensation and certain other adjustments which would be non-recurring in nature (“adjustment items”). Adjusted earnings from operations margin is an expression of the Company’s adjusted earnings from operations as a percentage of revenues. Adjusted EBITDA is defined as adjusted earnings from operations excluding depreciation and amortization. Adjusted EBITDA margin is an expression of the entity’s adjusted EBITDA as a percentage of revenues. Adjusted basic earnings per share is defined as adjusted net income on a basic per share basis, where adjusted net income is defined as adjusted earnings from operations less net finance costs and income tax expense, plus tax effects of adjustment items and adjusted for other significant items of a non-recurring nature. Non-cash working capital as a percentage of revenues is defined as the sum of accounts receivable, contract assets, inventories, deposits, prepaids and other assets, less accounts payable, accrued liabilities, provisions and contract liabilities divided by the trailing two fiscal quarter revenues annualized. Free cash flow is defined as cash provided by operating activities less property, plant and equipment and intangible asset expenditures. Net debt to adjusted EBITDA is the ratio of the net debt of the Company (cash and cash equivalents less bank indebtedness, long-term debt, and lease liabilities) to adjusted EBITDA. Order Bookings represent new orders for the supply of automation systems, services and products that management believes are firm. Organic Order Bookings are defined as Order Bookings in the stated period excluding Order Bookings from acquired companies for which the acquired company was not a part of the consolidated group in the comparable period. Organic Order Bookings growth compares the stated period organic Order Bookings with the reported Order Bookings of the comparable prior period. Order Backlog is the estimated unearned portion of revenues on customer contracts that are in process and have not been completed at the specified date. Book to bill ratio is a measure of Order Bookings compared to revenue.

Following amendments to ATS’ Restricted Stock Unit ("RSU") Plan in 2022 to provide for settlement in shares purchased in the open market and the creation of the employee benefit trust to facilitate such settlement, ATS began to account for equity-settled RSUs using the equity method of accounting. However, prior RSU grants which will be cash-settled and deferred stock unit ("DSU") grants which will be cash-settled are accounted for as described in the Company's annual consolidated financial statements and have significant volatility period over period based on the fluctuating price of ATS’ common shares. As a result, certain Non-IFRS Financial Measures (EBITDA, adjusted EBITDA, net debt to adjusted EBITDA, adjusted earnings from operations and adjusted basic earnings per share) were revised from previously disclosed values to exclude the impact on stock-based compensation expense of the revaluation of DSUs and RSUs resulting specifically from the change in market price of the Company's common shares between periods. Management believes that this adjustment provides further insight into the Company's performance, as share price volatility drives variability in the Company's stock-based compensation expense.

Operating margin, adjusted earnings from operations, EBITDA, EBITDA margin, adjusted EBITDA, and adjusted EBITDA margin are used by the Company to evaluate the performance of its operations. Management believes that earnings from operations is an important indicator in measuring the

28

performance of the Company’s operations on a pre-tax basis and without consideration as to how the Company finances its operations. Management believes that organic revenue and organic revenue growth, when considered with IFRS measures, allow the Company to better measure the Company's performance and evaluate long-term performance trends. Organic revenue growth also facilitates easier comparisons of the Company's performance with prior and future periods and relative comparisons to its peers. Management believes that EBITDA and adjusted EBITDA are important indicators of the Company’s ability to generate operating cash flows to fund continued investment in its operations. Management believes that adjusted earnings from operations, adjusted earnings from operations margin, adjusted EBITDA, adjusted net income and adjusted basic earnings per share are important measures to increase comparability of performance between periods. The adjustment items used by management to arrive at these metrics are not considered to be indicative of the business’ ongoing operating performance. Management uses the measure “non-cash working capital as a percentage of revenues” to assess overall liquidity. Free cash flow is used by the Company to measure cash flow from operations after investment in property, plant and equipment and intangible assets. Management uses net debt to adjusted EBITDA as a measurement of leverage of the Company. Order Bookings provide an indication of the Company’s ability to secure new orders for work during a specified period, while Order Backlog provides a measure of the value of Order Bookings that have not been completed at a specified point in time. Both Order Bookings and Order Backlog are indicators of future revenues that the Company expects to generate based on contracts that management believes to be firm. Organic Order Bookings and organic Order Bookings growth allow the Company to better measure the Company's performance and evaluation long-term performance trends. Organic Order Bookings growth also facilities easier comparisons of the Company's performance with prior and future periods and relative comparisons to its peers. Book to bill ratio is used to measure the Company’s ability and timeliness to convert Order Bookings into revenues. Management believes that ATS shareholders and potential investors in ATS use these additional IFRS measures and non-IFRS financial measures in making investment decisions and measuring operational results.

A reconciliation of (i) adjusted EBITDA and EBITDA to net income, (ii) adjusted earnings from operations to earnings from operations, (iii) adjusted net income to net income, (iv) adjusted basic earnings per share to basic earnings per share (v) free cash flow to its IFRS measure components and (vi) organic revenue to revenue, in each case for the three- and nine-months ended December 31, 2023 and January 1, 2023, is contained in this MD&A (see “Reconciliation of Non-IFRS Measures to IFRS Measures”). This MD&A also contains a reconciliation of (i) non-cash working capital as a percentage of revenues and (ii) net debt to their IFRS measure components, in each case at both December 31, 2023 and March 31, 2023 (see “Reconciliation of Non-IFRS Measures to IFRS Measures”). A reconciliation of Order Bookings and Order Backlog to total Company revenues for the three- and nine-months ended December 31, 2023 and January 1, 2023 is also contained in this MD&A (see “Order Backlog Continuity”).

ATS Corporation and its subsidiaries (collectively, “ATS” or the “Company”) uses its extensive knowledge base and global capabilities in custom automation, repeat automation, automation products and value-added solutions, including pre-automation and after-sales services, to address the sophisticated manufacturing automation systems and service needs of multinational customers.

The Company is listed on the Toronto Stock Exchange and New York Stock Exchange under the ticker symbol “ATS” and is incorporated and domiciled in Ontario, Canada. The address of its registered office is 730 Fountain Street North, Cambridge, Ontario, Canada.

The interim condensed consolidated financial statements of the Company for the three and nine months ended December 31, 2023 were authorized for issue by the Board of Directors (the “Board”) on February 6, 2024.

2. BASIS OF PREPARATION

These interim condensed consolidated financial statements were prepared on a historical cost basis, except for derivative instruments that have been measured at fair value. The interim condensed consolidated financial statements are presented in Canadian dollars and all values are rounded to the nearest thousand, except where otherwise stated.

Statement of compliance

These interim condensed consolidated financial statements are prepared in accordance with International Accounting Standard (“IAS”) 34 - Interim Financial Reporting. Accordingly, certain information and disclosures normally included in annual financial statements prepared in accordance with International Financial Reporting Standards (“IFRS”), as issued by the International Accounting Standards Board (“IASB”), have been omitted or condensed. These interim condensed consolidated financial statements should be read in conjunction with the annual consolidated financial statements of the Company for the year ended March 31, 2023.

Standards adopted in fiscal 2024

The accounting policies adopted in the preparation of these interim condensed consolidated financial statements are consistent with those followed in the presentation of the Company's annual consolidated financial statements for the year ended March 31, 2023, except as noted below:

(i) Amendments to IAS 12 - Income taxes

Effective May 23, 2023, the IASB issued International Tax Reform - Pillar Two Model Rules (Amendments to IAS 12 - Income Taxes ("IAS 12")). The amendments provide a mandatory immediate temporary exception to accounting for deferred taxes arising from the Organization for Economic Co-operation and Development's (OECD) international tax reform and introduce additional disclosure requirements for annual financial statements. The Company has applied the mandatory temporary exception to recognizing and disclosing information about deferred tax assets and liabilities related to Pillar Two income taxes. The adoption did not have an impact on the Company's interim condensed consolidated financial statements.

3. CRITICAL ACCOUNTING ESTIMATES AND ASSUMPTIONS

The preparation of the Company’s interim condensed consolidated financial statements requires management to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the end of the reporting period. However, uncertainty about these estimates, judgments and assumptions could result in outcomes that require a material adjustment to the carrying amount of the asset or liability affected in future periods.

The key assumptions concerning the future and other key sources of estimation uncertainty at the reporting date, which have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next fiscal year, are consistent with those disclosed in the Company’s fiscal 2023 audited consolidated financial statements.

The Company based its estimates, judgments and assumptions on parameters available when the interim condensed consolidated financial statements were prepared. Existing circumstances and assumptions about future developments, however, may change due to market changes or circumstances arising beyond the control of the Company. Such changes are reflected in the estimates when they occur.

4. ACQUISITIONS

(a) Current year acquisitions

(i) On November 16, 2023, the Company acquired 100% of the shares of Avidity Science, LLC ("Avidity"), a growing designer and manufacturer of automated water purification solutions for biomedical and life science applications. The total purchase price paid in the third quarter of fiscal 2024, pending post-closing adjustments was $271,948 ($198,611 U.S.).

Cash used in investing activities was determined as follows:
Cash consideration	$	271,948
Less: cash acquired	(6,100)
	$	265,848
The preliminary allocation of the purchase price at fair value is as follows:
Purchase price allocation
Cash	$	6,100
Other current assets	44,877
Property, plant and equipment	10,370
Right-of-use assets	4,687
Intangible assets with a definite life
Technology	44,911
Customer relationships	60,932
Other	2,790
Intangible assets with an indefinite life
Brands	28,207
Current liabilities	(20,850)
Other long-term liabilities	(5,346)
Deferred tax liability	(33,264)
Net identifiable assets	$	143,414
Residual purchase price allocated to goodwill	128,534
Purchase consideration	$	271,948

Current assets include accounts receivable of $17,616, representing the fair value of accounts receivable expected to be collected.

The purchase cost was allocated to the underlying assets acquired and liabilities assumed based upon the estimated fair values at the date of acquisition. The fair value of the assets acquired and the liabilities assumed have been determined on a provisional basis based on information that is currently available to the Company. Final valuations of certain assets including working capital, property, plant and equipment and intangible assets are not yet complete due to timing of the acquisition and the inherent complexity associated with valuations. The allocation to intangible assets has preliminarily been determined using relative values from comparable transactions. Specifically, a third-party valuation has not been finalized. Therefore, the purchase price allocation is preliminary and is subject to adjustment upon completion of the valuation process and analysis of resulting tax effects.

The primary factors that contributed to a residual purchase price that resulted in the recognition of goodwill are: the acquired workforce, access to growth opportunities in new markets and with existing customers, and the combined strategic value to the Company’s growth plan. Of the amounts assigned to goodwill and intangible assets, approximately 17% of the aggregate are not expected to be deductible for tax purposes. This acquisition was accounted for as a business combination with the Company as the acquirer of Avidity. The purchase method of accounting was used with an acquisition date of November 16, 2023. Avidity contributed approximately $13,797 in revenue and $524 in net income from the acquisition date November 16, 2023 to December 31, 2023. If Avidity had been acquired at the beginning of ATS' fiscal year (April 1, 2023), the Company estimates that revenues and net income of the combined Avidity and ATS entity for the nine months ended December 31, 2023 would have been approximately $68,987 and $2,622 higher, respectively.

(ii) On July 3, 2023, the Company acquired 100% of the shares of Odyssey Validation Consultants Limited ("Odyssey"), an Ireland-based provider of digitalization solutions for the life sciences industry. The total purchase price was $5,636 (3,898 Euros), including $269 (187 Euros) paid in the third quarter of fiscal 2024.

On June 30, 2023, the Company acquired 100% of the shares of Yazzoom B.V. (“Yazzoom”), a Belgium-based provider of artificial intelligence and machine learning based tools for industrial production. The purchase price, paid in the first quarter of fiscal 2024, was $5,283 (3,655 Euros).

Cash used in investing activities for the two acquisitions was determined as follows:
Cash consideration	$	10,919
Less: cash acquired	(939)
	$	9,980
The allocation of the purchase price at fair value for the two acquisitions is as follows:
Purchase price allocation
Cash	$	939
Other current assets	2,193
Property, plant and equipment	990
Right-of-use assets	423
Intangible assets with a definite life
Technology	2,856
Brands	1,318
Customer relationships	659
Other	1,429
Current liabilities	(3,895)
Other long-term liabilities	(377)
Deferred tax liability	(623)
Net identifiable assets	$	5,912
Residual purchase price allocated to goodwill	5,007
Purchase consideration	$	10,919

Current assets include accounts receivable of $1,351, representing the fair value of accounts receivable expected to be collected.

The purchase cost was allocated to the underlying assets acquired and liabilities assumed based upon the estimated fair values at the date of acquisition. The fair value of the assets acquired and the liabilities assumed have been finalized for Odyssey and Yazzoom. The allocations to intangible assets were determined using relative values from comparable transactions.

The primary factors that contributed to a residual purchase price that resulted in the recognition of goodwill are: the acquired workforce, access to growth opportunities in new markets and with existing customers, and the combined strategic value to the Company’s growth plan. The amounts assigned to goodwill and intangible assets are not expected to be deductible for tax purposes. These acquisitions were accounted for as business combinations with the Company as the acquirer of Yazzoom and Odyssey. The purchase method of accounting was used with an acquisition date of June 30, 2023 for Yazzoom, and July 3, 2023 for Odyssey.

(iii) On January 1, 2024, subsequent to the third quarter, the Company acquired IT.ACA. Engineering S.r.l. ("ITACA"), an Italian automation system integrator.

(b) Prior year acquisitions

(i) On March 28, 2023, the Company completed its acquisition of 100% of the membership interest in Triad Unlimited LLC (“Triad”), a U.S.-based reliability engineering service provider to the North American and European markets. The total purchase price paid upon finalization of working capital adjustments was $20,623 ($15,166 U.S.). Included in the purchase price was contingent consideration of $7,953 ($5,849 U.S.), which is payable if certain performance targets are met within two years of the acquisition date.

(ii) On March 3, 2023, the Company acquired 100% of the shares of Zi-Argus Australia Pty Ltd. and Zi-Argus Ltd. (“ZIA”). ZIA is an automation systems integrator serving Southeast Asia and Australia with a focus on process control, factory floor automation, data center and Industry 4.0 digitization solutions. The total purchase price paid in the fourth quarter of fiscal 2023, pending post-closing adjustments, was $24,500 ($18,015 U.S.).

The fair value of the assets acquired and the liabilities assumed have been determined on a provisional basis for ZIA and was finalized for Triad, based on information currently available to the Company. Final valuations of certain assets including intangible assets and working capital of ZIA are not yet complete due to the inherent complexity associated with valuations. As well, the purchase price of the ZIA acquisition is subject to post-closing adjustments. During the nine months ended December 31, 2023, changes to the purchase price allocation for the two acquisitions resulted in increases to purchase price of $283, cash of $336, intangible assets of $559, long-term debt of $421, the deferred tax liability of $92, decreases in working capital of $936, property, plant and equipment of $98, other long-term liabilities of $171 and an increase to goodwill of $764.

11. FINANCIAL INSTRUMENTS AND RISK MANAGEMENT

During the three and nine months ended December 31, 2023 and the three and nine months ended January 1, 2023, there were no changes in the classification of financial assets as a result of a change in the purpose or use of those assets.

During the three and nine months ended December 31, 2023 and the three and nine months ended January 1, 2023, there were no transfers of financial instruments between Level 1 and Level 2 fair value measurements, and no transfers into or out of Level 3 fair value measurements.

Instruments not subject to hedge accounting

As part of the Company’s risk management strategy, forward contract derivative financial instruments are used to manage foreign currency exposure related to the translation of foreign currency net assets to the subsidiary’s functional currency. As these instruments have not been designated as hedges, the change in fair value is recorded in selling, general and administrative expenses in the interim condensed consolidated statements of income.

For the three and nine months ended December 31, 2023, the Company recorded risk management gains of $1,487 and $6,333, respectively (three and nine months ended January 1, 2023 - losses of $17,875 and $20,739, respectively), on foreign currency risk management forward contracts in the

Warranty provisions

Warranty provisions are related to sales of products and are based on experience reflecting statistical trends of warranty costs.

Restructuring

Restructuring charges are recognized in the period incurred and when the criteria for provisions are fulfilled. Termination benefits are recognized as a liability and an expense when the Company is demonstrably committed through a formal restructuring plan.

The Company periodically undertakes reviews of its operations to ensure alignment with strategic market opportunities. As part of this review, the Company has identified an opportunity to improve the cost structure of the organization and reallocate investment to growth areas. In the third quarter of fiscal 2024, restructuring expenses of $16,228 were recorded in relation to the reorganization. The majority of the remaining actions are expected to be completed during the fourth quarter of fiscal 2024.

In fiscal 2023, the Company completed a reorganization plan which primarily impacted certain management positions.

Other provisions

Other provisions are related to medical insurance expenses that have been incurred during the period but are not yet paid, and other miscellaneous provisions.

13. BANK INDEBTEDNESS AND LONG-TERM DEBT

On October 5, 2023, the Company amended its senior secured credit facility (the “Credit Facility”) to extend the term loan maturity to match the maturity of the revolving line of credit. The Credit Facility consists of (i) a $750,000 secured committed revolving line of credit and (ii) a fully drawn $300,000 non-amortized secured term credit facility; both maturing on November 4, 2026. The Credit Facility is secured by the Company’s assets, including a pledge of shares of certain of the Company’s subsidiaries. Certain of the Company’s subsidiaries also provide guarantees under the Credit Facility. At

ATS CORPORATION

Notes to Interim Condensed Consolidated Financial Statements

(in thousands of Canadian dollars, except per share amounts - unaudited)

December 31, 2023, the Company had utilized $763,021 under the Credit Facility, of which $763,009 was classified as long-term debt (March 31, 2023 - $691,906) and $12 by way of letters of credit (March 31, 2023 - $48). During the nine months ended December 31, 2023, the Company drew $580,823 and repaid $541,973 on its Credit Facility, which included proceeds from the public offering of the Company's common shares on the New York Stock Exchange.

The Credit Facility is available in Canadian dollars by way of prime rate advances and/or bankers’ acceptances, in U.S. dollars by way of base rate advances and/or Term SOFR, in Euros by way of EURIBOR advances, in British pounds sterling by way of Daily Simple SONIA advances, and by way of letters of credit for certain purposes. The interest rates applicable to the Credit Facility are determined based on a net debt-to-EBITDA ratio as defined in the Credit Facility. For prime rate advances and base rate advances, the interest rate is equal to the bank’s prime rate or the bank’s U.S. dollar base rate in Canada, respectively, plus a margin ranging from 0.45% to 2.00%. For bankers’ acceptances, Term SOFR, EURIBOR advances and Daily Simple SONIA advances, the interest rate is equal to the bankers’ acceptance fee, Term SOFR rate, EURIBOR rate or Daily Simple SONIA rate, respectively, plus a margin that varies from 1.45% to 3.00%. The Company pays a fee for usage of financial letters of credit that ranges from 1.45% to 3.00%, and a fee for usage of non-financial letters of credit that ranges from 0.97% to 2.00%. The Company pays a standby fee on the unadvanced portions of the amounts available for advance or drawdown under the Credit Facility at rates ranging from 0.29% to 0.60%. The Company's Credit Facility is subject to changes in market interest rates. Changes in economic conditions outside of the Company's control could result in higher interest rates, thereby increasing its interest expense. The Company uses a variable for fixed interest rate swap to hedge a portion of its Credit Facility (see note 8).

The Credit Facility is subject to financial covenants including a net debt-to-EBITDA test and an interest coverage test. Under the terms of the Credit Facility, the Company is restricted from encumbering any assets with certain permitted exceptions. At December 31, 2023, all of the covenants were met.

The Company has additional credit facilities available of $104,157 (40,776 Euros, $24,000 U.S., 45,000 Thai Baht, 5,000 GBP, 5,000 CNY, $150 AUD and $1,462 CAD). The total amount outstanding on these facilities as at December 31, 2023 was $7,611, of which $5,179 was classified as bank indebtedness (March 31, 2023 - $5,824), $1,838 was classified as long-term debt (March 31, 2023 - $202) and $594 by way of letters of credit (March 31, 2023 - $158). The interest rates applicable to the credit facilities range from 0.03% to 8.45% per annum. A portion of the long-term debt is secured by certain assets of the Company.

The Company’s U.S. $350,000 aggregate principal amount of senior notes (“the Senior Notes”) were issued at par, bear interest at a rate of 4.125% per annum and mature on December 15, 2028. After December 15, 2023, the Company may redeem the Senior Notes, in whole at any time or in part from time to time, at specified redemption prices and subject to certain conditions required by the Senior Notes. If the Company experiences a change of control, the Company may be required to repurchase the Senior Notes, in whole or in part, at a purchase price equal to 101% of the aggregate principal amount of the Senior Notes, plus accrued and unpaid interest, if any, to, but not including, the redemption date. The Senior Notes contain customary covenants that restrict, subject to certain exceptions and thresholds, some of the activities of the Company and its subsidiaries, including the Company’s ability to dispose of assets, incur additional debt, pay dividends, create liens, make investments, and engage in specified transactions with affiliates.

During the three and nine months ended December 31, 2023, the Company granted nil and 176,112 time vesting stock options (nil and 223,144 in the three and nine months ended January 1, 2023, respectively). The stock options granted vest over four years and expire on the seventh anniversary from the date of issue.

(i) For the nine months ended December 31, 2023, the weighted average share price at the date of exercise was $58.20 (January 1, 2023 - $40.69).

The fair values of the Company’s stock options issued during the periods presented were estimated at the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions. Expected stock price volatility was determined at the time of the grant by considering historical share price volatility. Expected stock option grant life was determined at the time of the grant by considering the average of the grant vesting period and the grant exercise period.

Restricted Share Unit Plan:

During the three and nine months ended December 31, 2023, the Company granted 9,740 and 161,568 time-vesting restricted share units (“RSUs”) (4,921 and 203,300 in the three and nine months ended January 1, 2023), nil and 126,944 performance-based RSUs (nil and 152,690 in the three and nine months ended January 1, 2023). The Company measures these RSUs based on the fair value at the date of grant and a compensation expense is recognized over the vesting period in the interim condensed consolidated statements of income with a corresponding increase in contributed surplus. The performance-based RSUs vest upon successful achievement of certain operational and share price targets.

On May 18, 2022, the RSU plan was amended so that RSUs granted may be settled in ATS Common Shares, where deemed advisable by the Company, as an alternative to cash payments. It is the Company's intention to settle these RSUs with ATS Common Shares and therefore the Company measures these RSUs as equity awards based on fair value. At December 31, 2023, 725,290 shares are held in a trust and may be used to settle some or all of the RSU grants when they are fully vested. The trust is consolidated in the Company's interim condensed consolidated financial statements with the value of the acquired common shares presented as a reduction of share capital.

ATS CORPORATION

(in thousands of Canadian dollars, except per share amounts - unaudited)

The RSUs issued prior to May 18, 2022 give the employee the right to receive a cash payment based on the market value of a common share of the Company. The RSU liability is recognized quarterly based on the expired portion of the vesting period and the change in the Company’s stock price. The change in value of the RSU liability is included in the interim condensed consolidated statements of income in the period of the change. At December 31, 2023, the value of the outstanding liability related to the RSU plan was $17,129 (March 31, 2023 - $36,177). The RSU liability is included in accounts payable and accrued liabilities on the interim condensed consolidated statements of financial position.

The weighted average remaining vesting period for the time-vesting RSUs and performance-based RSUs to be settled in cash is 0.5 years.

Deferred Stock Unit Plan:

During the three and nine months ended December 31, 2023, the Company granted 3,103 and 32,498 units, respectively (three and nine months ended January 1, 2023 - nil and 33,998, respectively). The Deferred Stock Unit ("DSU") liability is revalued at each reporting date based on the change in the Company’s stock price. The change in value of the DSU liability is included in the interim condensed consolidated statements of income. As at December 31, 2023, the value of the outstanding liability related to the DSUs was $24,156 (March 31, 2023 - $22,565). The DSU liability is revalued at each reporting date based on the change in the Company’s stock price. The DSU liability is included in accounts payable and accrued liabilities on the interim condensed consolidated statements of financial position. The change in the value of the DSU liability is included in the interim condensed consolidated statements of income in the period of change.

The Company’s off-balance sheet arrangements consist of purchase obligations, primarily commitments for material purchases, which have been entered into in the normal course of business.

In accordance with industry practice, the Company is liable to customers for obligations relating to contract completion and timely delivery. In the normal conduct of its operations, the Company may provide letters of credit as security for advances received from customers pending delivery and contract performance. In addition, the Company provides letters of credit for post-retirement obligations and may provide letters of credit as security on equipment under lease and on order. As at December 31, 2023, the total value of outstanding letters of credit was approximately $176,730 (March 31, 2023 - $192,508).

In the normal course of operations, the Company is party to a number of lawsuits, claims and contingencies. Although it is possible that liabilities may be incurred in instances for which no accruals have been made, the Company does not believe that the ultimate outcome of these matters will have a material impact on its interim condensed consolidated statements of financial position.

1Non-IFRS Financial Measure - See “Non-IFRS and Other Financial Measures."

2Certain Non-IFRS Financial Measures have been revised from previously disclosed values to exclude the impact on stock-based compensation expense of the revaluation of deferred stock units and restricted share units resulting specifically from the change in market price of the Company's common shares between periods ("stock-based compensation revaluation expenses"). Management believes that this adjustment provides further insight into the Company's performance, as share price volatility drives variability in the Company's stock-based compensation expense.

Recent Acquisitions

On November 16, 2023, the Company acquired Avidity Science, LLC ("Avidity"), a growing designer and manufacturer of automated water purification solutions for biomedical and life science applications. The total purchase price paid in the third quarter of fiscal 2024, pending post-closing adjustments was $271.9 million (U.S. $198.6 million). Avidity serves a diverse global customer base of pharmaceutical, biopharma, healthcare, government, and academic research facilities. Avidity bolsters ATS' value proposition for both new and existing customers by providing researchers confidence in their data during key stages of drug discovery, development and testing.

On January 1, 2024, subsequent to the third quarter, the Company acquired IT.ACA. Engineering S.r.l., an Italian automation system integrator.

Third quarter summary

Fiscal 2024 third quarter revenues were 16.2% or $105.0 million higher than in the corresponding period a year ago. This performance reflected year-over-year organic revenue growth (growth excluding contributions from acquired companies and foreign exchange translation) of $59.2 million or 9.1%, and revenues earned by acquired companies of $29.7 million, most notably $13.8 million from Avidity

Science, LLC ("Avidity"), which was acquired in the third quarter of fiscal 2024. Foreign exchange translation positively impacted revenues by $16.1 million or 2.5%, primarily reflecting the strengthening of the Euro relative to the Canadian dollar. Revenues generated from construction contracts increased 14.9% or $63.0 million due to organic revenue growth combined with positive foreign exchange translation impact. Revenues from services increased 23.2% or $28.8 million due to revenues earned by acquired companies of $18.0 million in addition to organic revenue growth and the positive impact of foreign exchange translation. Revenues from the sale of goods increased 13.1% or $13.2 million primarily due to revenues earned by acquired companies of $11.2 million in addition to a positive foreign exchange translation impact.

By market, revenues generated in life sciences increased $12.7 million or 4.2% year over year. This was primarily due to contributions from acquisitions totalling $18.2 million and the positive impact of foreign exchange translation, partially offset by revenues earned a year ago on a large $120.0 million program. Revenues in transportation increased $78.8 million or 48.8%, due to timing of program execution and on higher Order Backlog entering the third quarter of fiscal 2024, driven primarily by EV Order Bookings, including previously announced EV Order Bookings of U.S. $578.2 million. Revenues generated in food & beverage increased $6.4 million or 7.2% due to revenues earned by acquired companies and the positive impact of foreign exchange translation. Revenues generated in consumer products decreased $0.9 million or 1.3%. Revenues in energy increased $8.0 million or 34.9% due to higher Order Backlog entering the period as compared to the prior year and $3.5 million of contributions from acquisitions.

Net income for the third quarter of fiscal 2024 was $47.2 million (48 cents per share basic), compared to $29.2 million (32 cents per share basic) for the third quarter of fiscal 2023. The increase primarily reflected higher revenues, partially offset by higher cost of revenues, selling, general and administrative ("SG&A") expenses, and restructuring charges. Adjusted basic earnings per share were 65 cents compared to 56 cents in the third quarter of fiscal 2023 (see “Reconciliation of Non-IFRS Measures to IFRS Measures”).

Depreciation and amortization expense was $35.2 million in the third quarter of fiscal 2024, compared to $27.9 million a year ago; the increase was primarily related to incremental depreciation and amortization expense from recently acquired companies.

EBITDA was $113.7 million (15.1% EBITDA margin) in the third quarter of fiscal 2024 compared to $83.9 million (13.0% EBITDA margin) in the third quarter of fiscal 2023. EBITDA for the third quarter of fiscal 2024 included $16.2 million of restructuring charges, $0.9 million of incremental costs related to acquisition activity, $0.8 million of acquisition-related fair value adjustments to acquired inventories, a $0.6 million recovery of stock-based compensation expenses due to revaluation, and an $11.7 million gain on sale of facilities. EBITDA for the corresponding period in the prior year included $0.7 million of incremental costs related to acquisition activity, $10.5 million of restructuring charges, and $5.6 million of stock-based compensation revaluation expenses. Excluding these costs, adjusted EBITDA was $119.3 million (15.9% adjusted EBITDA margin), compared to $100.7 million (15.6% adjusted EBITDA margin) for the corresponding period in the prior year. Higher adjusted EBITDA reflected higher revenues partially offset by increased SG&A expenses. EBITDA is a non-IFRS measure - see “Non-IFRS and Other Financial Measures.”

Order Bookings

Third quarter fiscal 2024 Order Bookings were $668 million, a 31.8% year over year decrease, reflecting an organic Order Bookings decline of 36.2%, primarily related to the transportation market, partially offset by 3.0% growth from acquired companies, in addition to a 1.4% increase due to foreign exchange rate translation of Order Bookings from foreign-based ATS subsidiaries, primarily reflecting the strengthening of the Euro relative to the Canadian dollar. Order Bookings from acquired companies totalled $29.0 million. By market, Order Bookings in life sciences increased compared to the prior-year period primarily due to $18.1 million of contributions from acquired companies, organic growth and a positive foreign exchange rate translation of Order Bookings from foreign-based ATS subsidiaries. Order Bookings in transportation decreased compared to the prior-year period, as a result of variability on timing of large EV orders. Third quarter fiscal 2023 included Order Bookings of U.S. $221.3 million (approximately $300.2 million CAD) from a global automotive customer to move towards fully automated battery assembly systems for their North American manufacturing operations. Order Bookings in food & beverage increased compared to the prior-year period primarily due to foreign exchange rate translation of Order Bookings from foreign-based ATS subsidiaries. Order Bookings in consumer products increased primarily due to the timing of customer projects and contributions from acquired companies. Order Bookings in energy decreased primarily due to timing of customer projects.

Trailing twelve month book-to-bill ratio at December 31, 2023 was 0.95:1. Book-to-bill ratio is a supplementary financial measure - see “Non-IFRS and Other Financial Measures.”

Backlog

At December 31, 2023, Order Backlog was $1,907 million, 11.0% lower than at January 1, 2023 primarily on account of lower Order Backlog within the transportation market where several large, strategic Order Bookings were included a year ago.

Outlook

The life sciences funnel remains strong, with a focus on strategic submarkets of pharmaceuticals, radiopharmaceuticals, and medical devices such as auto-fillers and auto-injectors. Management continues to see opportunities with both new and existing customers, including those customers using auto-injectors for diabetes and obesity treatments, and producers of contact lens and pre-filled syringes, as well as opportunities to provide life science solutions that leverage various integrated capabilities to serve broader customer needs. In transportation, the funnel largely includes strategic

opportunities related to electric vehicles, as the global automotive industry continues to shift towards EV production. The strategic nature of EV programs can result in larger average order values, resulting in variability in Order Bookings. Management believes the Company's automated EV battery pack and assembly capabilities position ATS well within the industry. Management is working with one of its EV customers to support their revised timing on a portion of an existing program as the customer works to realign their production schedules. The near-term market for electric vehicles remains dynamic as automotive Original Equipment Manufacturers look to align capacity to end-market demand and lower platform costs, however the longer-term fundamentals remain intact and the transportation funnel is strong and reflects diversified, long-term opportunities. Funnel activity in food & beverage remains strong, particularly for energy-efficient solutions. The Company continues to benefit from strong brand recognition within the global tomato processing industry, and there is ongoing interest in automated solutions with the food & beverage market. Funnel activity in consumer products is stable; inflationary pressures continue to have an effect on discretionary spending, which may impact timing of some customer investments. Funnel activity in energy remains strong and includes some longer-term opportunities in the nuclear industry. The Company is focused on clean energy applications including solutions for the refurbishment of nuclear power plants, early participation in the small modular reactor market, and grid battery storage. Across all markets, customers are exercising normal caution in their approach to investment and spending. Funnel growth in markets where environmental, social and governance ("ESG") requirements are an increasing focus for customers — including grid battery storage, EV and nuclear, as well as consumer goods packaging — provide ATS with opportunities to use its capabilities to respond to customer sustainability standards and goals, including global and regional requirements to reduce carbon emissions. Customers seeking to de-risk or enhance the resiliency of their supply chains, address a shortage of skilled workers or combat higher labour costs also provide future opportunities for ATS to pursue. Management believes that the underlying trends driving customer demand for ATS solutions including rising labour costs, labour shortages, production onshoring or reshoring and the need for scalable, high-quality, energy-efficient production remain favourable.

Order Backlog of $1,907 million is expected to help mitigate some of the impact of quarterly variability in Order Bookings on revenues in the short term. The Company’s Order Backlog includes several large enterprise programs that have longer periods of performance and therefore longer revenue recognition cycles. These programs have extended the average period over which the Company expects to convert its Order Backlog to revenues, providing ATS with longer visibility. In the fourth quarter of fiscal 2024, management expects the conversion of Order Backlog to revenues to be in the 36% to 39% range. This estimate is calculated each quarter based on management’s assessment of project schedules across all customer contracts, expectations for faster-turn product and services revenues, expected delivery timing of third-party equipment and operational capacity. The fourth-quarter conversion range accounts for the impact of approximately $200 million of Order Backlog with one of the Company's EV customers that has been delayed, as noted above. Management expects that the program will restart in the first quarter of fiscal 2025.

The timing of customer decisions on larger opportunities is expected to cause variability in Order Bookings from quarter to quarter. Revenues in a given period are dependent on a combination of the volume of outstanding projects the Company is contracted to, the size and duration of those projects, and the timing of project activities including design, assembly, testing, and installation. Given the specialized nature of the Company’s offerings, the size and scope of projects vary based on customer needs. The Company seeks to achieve revenue growth organically and by identifying strategic

acquisition opportunities that provide access to attractive end-markets and new products and technologies and deliver hurdle-rate returns.

In the short term, ATS will continue to mitigate supply chain volatility, which has been contributing to longer lead times and cost increases in the supply base over the past several quarters. However, prolonged cost increases and price volatility have and may continue to disrupt the timing and progress of the Company’s margin expansion efforts and affect revenue recognition. In addition, with a portion of Order Backlog related to one of the Company's EV programs currently delayed, Management expects to see near-term margin pressure in its Transportation business. Over time, sustaining management's margin target assumes that the Company will successfully implement the initiatives noted below, and that such initiatives will result in improvements to its adjusted earnings from operations margin that offset these shorter-term pressures (see “Forward-Looking Statements” for a description of the risks underlying the achievement of the margin target in future periods).

The Company regularly monitors customers for changes in credit risk and does not believe that any single industry or geographic region represents significant credit risk.

In the short term, the Company expects non-cash working capital to remain elevated as large enterprise programs progress through milestones. Over the long-term, the Company expects to continue investing in non-cash working capital to support growth, with fluctuations expected on a quarter-over-quarter basis. The Company’s long-term goal is to maintain its investment in non-cash working capital as a percentage of annualized revenues below 15%. However, given the size and timing of milestone payments for certain large EV programs in Order Backlog, the Company could see its working capital exceed 15% of annualized revenues in certain periods as it did in the first three quarters of fiscal 2024. The Company expects that continued cash flows from operations, together with cash and cash equivalents on hand and credit available under operating and long-term credit facilities will be sufficient to fund its requirements for investments in non-cash working capital and capital assets, and to fund strategic investment plans including some potential acquisitions. Acquisitions could result in additional debt or equity financing requirements for the Company. Non-cash working capital as a percentage of revenues is a Non-IFRS ratio - see “Non-IFRS and Other Financial Measures.”

Management is pursuing several initiatives to grow revenues and improve profitability with the goal of expanding its adjusted earnings from operations margin to 15% over time through a combination of operational initiatives and portfolio development. Operational initiatives include a focus on pursuing continuous improvement in all business activities through the ATS Business Model, including in acquired businesses, improving global supply chain management, increasing the use of standardized platforms and technologies, and growing revenues while leveraging the Company’s cost structure. Portfolio development initiatives include efforts to grow the Company's products and after-sales service revenues as a percentage of overall revenues. After-sales revenues and reoccurring revenues, which ATS defines as revenues from ancillary products and services associated with equipment sales, and revenues from customers who purchase non-customized ATS product at regular intervals, are expected to provide some balance to customers' capital expenditure cycles. Management estimates that reoccurring revenues are currently in the range of 25% to 35% of total revenues on a trailing twelve-month basis. Moreover, the Company's financial profile, which has included strong growth, margin expansion and disciplined working capital investment, has allowed it to generate free cash flows that are reinvested back into the business. Management also sees the development of the Company's digitalization capabilities as another key area of growth for the portfolio, including the collection and

interpretation of data to drive meaningful change that optimizes performance for customers. In addition, management is focused on investing in innovation and employing a consistent, strategic approach to acquisitions. The Company continues to make progress in line with its plans to integrate acquired companies, and expects to realize cost and revenue synergies consistent with announced integration plans.

Reorganization Activity

The Company periodically undertakes reviews of its operations to ensure alignment with strategic market opportunities. As a part of this review, the Company has identified and previously announced an opportunity to improve the cost structure of the organization and reallocate investment to growth areas. In the third quarter of fiscal 2024, restructuring expenses of $16.2 million were recorded in relation to the reorganization. The majority of the remaining actions are expected to be completed during the fourth quarter of fiscal 2024. The total estimated cost of these activities is expected to be at the higher end of the previously disclosed range of $15 million to $20 million.

Notice to Reader: Non-IFRS and Other Financial Measures

Throughout this document, management uses certain non-IFRS financial measures, non-IFRS ratios and supplementary financial measures to evaluate the performance of the Company.

The terms “EBITDA”, "organic revenue", “adjusted net income”, “adjusted earnings from operations”, “adjusted EBITDA”, “adjusted basic earnings per share”, and “free cash flow”, are non-IFRS financial measures, “EBITDA margin”, “adjusted earnings from operations margin”, “adjusted EBITDA margin”, "organic revenue growth", “non-cash working capital as a percentage of revenues”, and “net debt to adjusted EBITDA” are non-IFRS ratios, and "operating margin", “Order Bookings”, "organic Order Bookings", "organic Order Bookings growth", “Order Backlog”, and “book-to-bill ratio” are supplementary financial measures, all of which do not have any standardized meaning prescribed within IFRS and therefore may not be comparable to similar measures presented by other companies. Such measures should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. In addition, management uses “earnings from operations”, which is an additional IFRS measure, to evaluate the performance of the Company. Earnings from operations is presented on the Company’s consolidated statements of income as net income excluding income tax expense and net finance costs. Operating margin is an expression of the Company’s earnings from operations as a percentage of revenues. EBITDA is defined as earnings from operations excluding depreciation and amortization. EBITDA margin is an expression of the Company’s EBITDA as a percentage of revenues. Organic revenue is defined as revenues in the stated period excluding revenues from acquired companies for which the acquired company was not a part of the consolidated group in the comparable period. Organic revenue growth compares the stated period organic revenue with the reported revenue of the comparable prior period. Adjusted earnings from operations is defined as earnings from operations before items excluded from management’s internal analysis of operating results, such as amortization expense of acquisition-related intangible assets, acquisition-related transaction and integration costs, restructuring charges, the mark-to-market adjustment on stock-based compensation and certain other adjustments which would be non-recurring in nature (“adjustment items”). Adjusted earnings from operations margin is an expression of the Company’s adjusted earnings from operations as a percentage of revenues. Adjusted EBITDA is defined as adjusted earnings from operations excluding depreciation and amortization. Adjusted EBITDA margin is an expression of the entity’s adjusted EBITDA as a percentage of revenues. Adjusted basic earnings per share is defined as adjusted net income on a basic per share basis, where adjusted net income is defined as adjusted earnings from operations less net finance costs and income tax expense, plus tax effects of adjustment items and adjusted for other significant items of a non-recurring nature. Non-cash working capital as a percentage of revenues is defined as the sum of accounts receivable, contract assets, inventories, deposits, prepaids and other assets, less accounts payable, accrued liabilities, provisions and contract liabilities divided by the trailing two fiscal quarter revenues annualized. Free cash flow is defined as cash provided by operating activities less property, plant and equipment and intangible asset expenditures. Net debt to adjusted EBITDA is the ratio of the net debt of the Company (cash and cash equivalents less bank indebtedness, long-term debt, and lease liabilities) to adjusted EBITDA. Order Bookings represent new orders for the supply of automation systems, services and products that management believes are firm. Organic Order Bookings are defined as Order Bookings in the stated period excluding Order Bookings from acquired companies for which the acquired company was not a part of the consolidated group in the comparable period. Organic Order Bookings growth compares the stated period organic Order Bookings with the reported Order Bookings of the comparable prior period. Order Backlog is the estimated unearned portion of revenues on customer contracts that are in process and

have not been completed at the specified date. Book to bill ratio is a measure of Order Bookings compared to revenue.

Following amendments to ATS’ Restricted Stock Unit ("RSU") Plan in 2022 to provide for settlement in shares purchased in the open market and the creation of the employee benefit trust to facilitate such settlement, ATS began to account for equity-settled RSUs using the equity method of accounting. However, prior RSU grants which will be cash-settled and deferred stock unit ("DSU") grants which will be cash-settled are accounted for as described in the Company's annual consolidated financial statements and have significant volatility period over period based on the fluctuating price of ATS’ common shares. As a result, certain Non-IFRS Financial Measures (EBITDA, adjusted EBITDA, net debt to adjusted EBITDA, adjusted earnings from operations and adjusted basic earnings per share) were revised from previously disclosed values to exclude the impact on stock-based compensation expense of the revaluation of DSUs and RSUs resulting specifically from the change in market price of the Company's common shares between periods. Management believes that this adjustment provides further insight into the Company's performance, as share price volatility drives variability in the Company's stock-based compensation expense.

Operating margin, adjusted earnings from operations, EBITDA, EBITDA margin, adjusted EBITDA, and adjusted EBITDA margin are used by the Company to evaluate the performance of its operations. Management believes that earnings from operations is an important indicator in measuring the performance of the Company’s operations on a pre-tax basis and without consideration as to how the Company finances its operations. Management believes that organic revenue and organic revenue growth, when considered with IFRS measures, allow the Company to better measure the Company's performance and evaluate long-term performance trends. Organic revenue growth also facilitates easier comparisons of the Company's performance with prior and future periods and relative comparisons to its peers. Management believes that EBITDA and adjusted EBITDA are important indicators of the Company’s ability to generate operating cash flows to fund continued investment in its operations. Management believes that adjusted earnings from operations, adjusted earnings from operations margin, adjusted EBITDA, adjusted net income and adjusted basic earnings per share are important measures to increase comparability of performance between periods. The adjustment items used by management to arrive at these metrics are not considered to be indicative of the business’ ongoing operating performance. Management uses the measure “non-cash working capital as a percentage of revenues” to assess overall liquidity. Free cash flow is used by the Company to measure cash flow from operations after investment in property, plant and equipment and intangible assets. Management uses net debt to adjusted EBITDA as a measurement of leverage of the Company. Order Bookings provide an indication of the Company’s ability to secure new orders for work during a specified period, while Order Backlog provides a measure of the value of Order Bookings that have not been completed at a specified point in time. Both Order Bookings and Order Backlog are indicators of future revenues that the Company expects to generate based on contracts that management believes to be firm. Organic Order Bookings and organic Order Bookings growth allow the Company to better measure the Company's performance and evaluation long-term performance trends. Organic Order Bookings growth also facilities easier comparisons of the Company's performance with prior and future periods and relative comparisons to its peers. Book to bill ratio is used to measure the Company’s ability and timeliness to convert Order Bookings into revenues. Management believes that ATS shareholders and potential investors in ATS use these additional IFRS measures and non-IFRS financial measures in making investment decisions and measuring operational results.

A reconciliation of (i) adjusted EBITDA and EBITDA to net income, (ii) adjusted earnings from operations to earnings from operations, (iii) adjusted net income to net income, (iv) adjusted basic earnings per share to basic earnings per share (v) free cash flow to its IFRS measure components and (vi) organic revenue to revenue, in each case for the three- and nine-months ended December 31, 2023 and January 1, 2023 is contained in this document (see “Reconciliation of Non-IFRS Measures to IFRS Measures”). This document also contains a reconciliation of (i) non-cash working capital as a percentage of revenues and (ii) net debt to their IFRS measure components, in each case at both December 31, 2023 and March 31, 2023 (see “Reconciliation of Non-IFRS Measures to IFRS Measures”). A reconciliation of Order Bookings and Order Backlog to total Company revenues for the three- and nine-months ended December 31, 2023 and January 1, 2023 is also contained in this news release (see “Order Backlog Continuity”).
