TMX GROUP LIMITED REPORTS RESULTS FOR THIRD QUARTER OF 2023

TMX Group Ltd. has released results for the third quarter ended Sept. 30, 2023.

Commenting on results for the first nine months of 2023, John McKenzie, chief executive officer of TMX Group, said:

"TMX's positive results for the first three quarters of 2023 stand as compelling evidence of the enduring efficacy of our long-term strategy to diversify, globalize and innovate across our business. Higher overall revenue was driven by double-digit, year-over-year growth from global solutions, insights and analytics, including Trayport and TMX Datalinx, and increased revenue from derivatives trading and clearing, excluding BOX. Partially offsetting these increases, revenue from capital raising activity, and equities and fixed income trading, was lower compared to the first nine months of 2022 due to persistent challenges in market conditions. Moving forward, TMX's priority focus is on serving clients around the world with excellence, while pushing the evolution of the organization to meet the needs of modern capital markets stakeholders long into the future."

Commenting on performance in the third quarter of 2023, David Arnold, chief financial officer of TMX Group, said:

"Our financial results for the third quarter once again reflect the intrinsic strength of our balanced business model, as we achieved positive revenue and earnings-per-share growth amidst challenging market conditions. TMX reported 8-per-cent growth in revenue and 7-per-cent growth in diluted earnings per share (3 per cent on an adjusted basis) year over year, reflecting increases across some of our key business areas. Higher overall revenue was driven by increases from recurring sources, a 19-per-cent increase in revenue from GSIA, including Trayport and TMX Datalinx, and higher revenue from derivatives trading and clearing (excluding BOX), and CDS. Increases were partially offset by the negative impacts of lower activity in capital raising and equities trading."

1 Adjusted diluted earnings per share is a non-GAAP ratio.

Quarter ended Sept. 30, 2023 (Q3 2023) compared with quarter ended Sept. 30, 2022 (Q3 2022) 5

Net income attributable to equity holders of TMX Group and earnings per share

Net income attributable to equity holders of TMX Group in Q3 2023 was $85.3-million, or 31 cents per common share on a basic and diluted basis, compared with a net income attributable to equity holders of TMX Group of $81.0-million, or 29 cents per common share on a basic and diluted basis for Q3 2022. The increase in net income attributable to equity holders of TMX Group reflects an increase in income from operations of $2.7-million from Q3 2022 to Q3 2023 driven by an increase in revenue of $20.5-million partially offset by an increase in operating expenses of $17.8-million. The increase in revenue from Q3 2022 to Q3 2023 reflects higher revenue from global solutions, insights and analytics, derivatives trading and clearing (excluding BOX), CDS, and TSX Trust, partially offset by lower listings, equity and fixed income trading, and BOX Options Market LLC (BOX) revenue. Q3 2023 revenue also included $1.8-million related to Wall Street Horizon Inc. (acquired Nov. 9, 2022). The higher expenses included $6.7-million related to BOX's estimate of increased expenses for services provided by BOX Exchange LLC (8), as well as approximately $2.1-million of expenses related to WSH, of which there was approximately $400,000 related to amortization of acquired WSH intangibles. There were also higher expenses reflecting higher head count and payroll costs, employee performance incentive plan costs, consulting and legal fees, and IT (information technology) operating costs. Somewhat offsetting these increases was $3.5-million in integration costs related to AST Canada incurred in Q3 2022.

5 TMX Group completed a five-for-one split of its common shares outstanding (the Stock Split) effective at the close of business on June 13, 2023. All common share numbers and per share amounts in this release, including comparative figures, have been adjusted to reflect the Stock Split.

6 Adjusted net income is a non-GAAP measure, see discussion under the heading "Non-GAAP Measures".

7 Adjusted earnings per share is a non-GAAP ratio, see discussion under the heading "Non-GAAP Measures".

8 BOX Exchange LLC is a national securities exchange registered with the Securities and Exchange Commission, and is responsible for regulating and monitoring activities of BOX Options Market LLC, to ensure compliance with BOX Exchange rules and U.S. federal securities laws. TMX has a 40 per cent equity and a 20 per cent voting interest in BOX Exchange LLC.

The increase in earnings per share was also partially attributable to decreased net finance costs, somewhat offset by an increase in the number of weighted average common shares outstanding from Q3 2022 to Q3 2023, and higher income tax expense.

Adjusted net income attributable to equity holders of TMX Group (9) and adjusted earnings per share (10) reconciliation for Q3 2023 and Q3 2022 (11)

The financial results have been adjusted for the following:

• The amortization expenses of intangible assets in Q3 2022 and Q3 2023 related to the 2012 Maple transaction (TSX, TSXV, MX, CDS, Alpha, Shorcan), TSX Trust, Trayport (including VisoTech and Tradesignal), AST Canada, and BOX, and the amortization of intangibles related to WSH in Q3 2023. These costs are a component of Depreciation and amortization expenses.
• Fair value gain on contingent consideration, reflecting a reduction in the earn-out liability assumed as part of the WSH acquisition in Q4/22. The gain is included in Net Finance Costs.
• Integration costs related to integrating the AST Canada acquisition in Q3 2022. These costs are included in Depreciation and amortization,
• Compensation and benefits and Selling, general and administration.
• A decrease in deferred income tax liabilities which decreased income tax expenses in Q3 2022 relating to a decrease in the Pennsylvania and Nebraska future income tax rates.

9 Adjusted net income is a non-GAAP measure, see discussion under the heading "Non-GAAP Measures". 10 Adjusted earnings per share is a non-GAAP ratio, see discussion under the heading "Non-GAAP Measures". 11 TMX Group completed a five-for-one split of its common shares outstanding (the Stock Split) effective at the close of business on June 13, 2023. All common share numbers and per share amounts in this release, including comparative figures, have been adjusted to reflect the Stock Split. 12 Includes amortization expense of acquired intangibles including BOX, AST Canada, and Tradesignal in Q3 2022 and Q3 2023 and WSH in Q3 2023 13 Includes costs related to the integration of AST Canada (acquired August 12, 2021) in Q3 2022. 14 For additional information, see discussion under the heading "Additional Information - Net Finance Costs".

15 Future reductions in income tax rates in Pennsylvania and Nebraska.

16 Adjusted net income is a non-GAAP measure, see discussion under the heading "Non-GAAP Measures".

Adjusted net income attributable to equity holders of TMX Group increased by 3 per cent from $93.7-million in Q3 2022 to $96.8-million in Q3 2023 largely driven by higher revenue and lower net finance costs, partially offset by higher operating expenses and higher income tax expense.

Adjusted diluted earnings per share increased by 1 cent from 34 cents in Q3 2022 to 35 cents in Q3 2023, reflecting an increase in income from operations and lower net finance costs. The increase in adjusted earnings per share was somewhat offset by an increase in the number of weighted average common shares outstanding and higher income tax expense from Q3 2022 to Q3 2023.

17 Includes amortization expense of acquired intangibles including BOX, AST Canada, and Tradesignal in Q3 2022 and Q3 2023, and WSH in Q3 2023.

18 Includes costs related to the integration of AST Canada (acquired August 12, 2021) in Q3 2022.

19 Adjusted earnings per share is a non-GAAP ratio, see discussion under the heading "Non-GAAP Measures". Fair Value Gain on Contingent Consideration and Change in Deferred Income Tax Liabilities Relating to Changes in Future Tax Rates are not presented in the reconciliation due to the size of the adjustment being less than a penny.

Revenue

Revenue was $287.3-million in Q3 2023, up $20.5-million or 8 per cent from $266.8-million in Q3 2022, attributable to increases in revenue from global solutions, insights and analytics, derivatives trading and clearing (excluding BOX), and equities and fixed income trading, and clearing, partially offset by decreases in capital formation and a $1.9-million decrease in BOX revenue. The increase in revenue from Q3 2022 to Q3 2023 included $1.8-million of revenue for WSH (acquired Nov. 9, 2022). Excluding revenue from WSH, revenue was up 7 per cent in Q3 2023 compared with Q3 2022.

Operating expenses

Operating expenses in Q3 2023 were $162.0-million, up $17.8-million or 12 per cent, from $144.2-million in Q3 2022, primarily driven by $6.7-million related to BOX's estimate of increased expenses ($4.6-million in H1 2023 and the remaining $2.1-million in Q3 2023) for services provided by BOX Exchange LLC. The increase from Q3 2022 to Q3 2023 included approximately $2.1-million related to WSH (acquired Nov. 9, 2022), of which there was approximately $400,000 related to WSH's amortization of acquired intangibles. There were also higher expenses reflecting higher head count and payroll costs, employee performance incentive plan costs, consulting and legal fees, and increased IT operating costs.

Somewhat offsetting these increases was $3.5-million in integration costs related to AST Canada incurred in Q3 2022.

Excluding the above-mentioned expenses for BOX, WSH and AST Canada, operating expenses increased 9 per cent in Q3 2023 compared with Q3 2022.

Additional Information

Share of (loss) income from equity-accounted investments

In Q3 2023, our share of loss from equity-accounted investments decreased by $0.3-million. For Q3 2023, our share of (loss) income from equity-accounted investments includes VettaFi20, Ventriks, and other equity accounted investments, compared with Q3 2022, which included SigmaLogic and Ventriks.

Net finance costs

The decrease in net finance costs from Q3 2022 to Q3 2023 reflected higher interest income on funds invested of $4.5-million as a result of higher interest rates, and a $0.1-million fair value gain on contingent consideration, reflecting a reduction in the earn-out liability assumed as part of the WSH acquisition, somewhat offset by higher interest expense on borrowings, and higher foreign exchange losses of $0.8-million.

Income tax expense and effective tax rate

Excluding adjustments, primarily related to the items noted below, the effective tax rate would have been approximately 27 per cent, excluding NCI, for Q3 2023, an increase of 1 per cent from Q3 2022 primarily due to an increase in the U.K. corporate income tax rate from 19 per cent to 25 per cent effective April 1, 2023. A blended tax rate of 23.5 per cent was applied through the tax year as required for corporations with a December 31st year-end.

In Q3 2023, there were non-taxable FX gains resulting from the unrealized translation of monetary assets and liabilities.

In Q3 2022, Pennsylvania and Nebraska announced future reductions in income tax rates, which decreased the deferred income tax liabilities, resulting in a corresponding decrease in income tax expense.

Net income attributable to non-controlling interests

The decrease in net income attributable to non-controlling interests (NCI) for Q3 2023 compared to Q3 2022 is primarily due to lower net income in BOX driven by lower revenue and higher operating expenses, including an increase in BOX's estimate of expenses for services provided by BOX Exchange LLC.

Net income attributable to equity holders of TMX Group in FNM/23 was $271.6-million, or $0.98 per common share on a basic and $0.97 on a diluted basis, compared with $440.5-million, or $1.58 per common share on a basic and $1.57 on a diluted basis, for FNM/22. The decrease in net income attributable to equity holders of TMX Group is largely due to a non-cash gain of $177.9-million being recognized in Q1/22 resulting from the revaluation of our interest in BOX upon acquisition of voting control, partially offset by an increase in income from operations of $9.9-million. The increase in income from operations from FNM/22 to FNM/23 was driven by an increase in revenue of $53.4-million, reflecting higher revenue from Global Solutions, Insights and Analytics, TSX Trust, Derivatives Trading and Clearing (excl. BOX), and CDS, partially offset by lower Listing, Equity and Fixed Income trading, and BOX revenue. The revenue increase also included $5.3-million related to WSH, and $0.2-million for SigmaLogic. There was also an increase in operating expenses of $43.5-million, which included $8.0-million of expenses related to SigmaLogic, WSH, and VettaFi, of which there was approximately $1.5-million related to amortization of acquired intangibles for WSH, as well as $0.8-million related to acquisition and related expenses for SigmaLogic, WSH and VettaFi.

Income tax expense and effective tax rate

Excluding adjustments, primarily related to the items listed below, the effective tax rate would have been approximately 27 per cent, excluding NCI, for FNM/23, an increase of 1 per cent from FNM/22 primarily due to an increase in the U.K. corporate income tax rate from 19 per cent to 25 per cent effective April 1, 2023.

In FNM/22, Pennsylvania and Nebraska announced future reductions in income tax rates, which decreased the deferred income tax liabilities, resulting in a corresponding decrease in income tax expense.

Net income attributable to non-controlling interests

The decrease in net income attributable to non-controlling interests (NCI) for FNM/23 compared to FNM/22 is primarily due to lower net income in BOX driven by lower revenue and higher operating expenses, including an increase in BOX's estimate of expenses for services provided by BOX Exchange LLC.
