Open on SEC ↗

Exhibit 99.1 TransDigm Group Reports Fiscal 2026 Fourth Quarter and Year-End Results Cleveland, Ohio, November 10, 2026/PRNewswire/ -- TransDigm Group Incorporated (NYSE: TDG), a leading global designer, producer and supplier of highly engineered aircraft components, today reported results for the fourth quarter ended September 30, 2026.

Net sales of $2,988 million, up 23% from $2,437 million in the prior year's quarter;

• EBITDA As Defined of $1,583 million, up 20% from $1,320 million in the prior year's quarter; and

• Adjusted earnings per share of $12.44, up 15% from $10.82 in the prior year's quarter.

Net sales for the quarter increased 23%, or $551 million, to $2,988 million from $2,437 million in the comparable quarter a year ago. Organic sales growth as a percentage of net sales was 14%.

Net income for the quarter was $586 million, a decrease of $23 million, or 4%, compared to $609 million in the comparable quarter a year ago. The decrease in net income primarily reflects higher interest expense as a result of the increase in TransDigm's year-over-year gross debt balance and higher tax expense. The decrease was offset by the increase in net sales as described above and the application of our operating strategy.

Adjusted net income for the quarter increased 12% to $706 million, or $12.44 per share, from $629 million, or $10.82 per share, in the comparable quarter a year ago.

EBITDA for the quarter increased 13% to $1,436 million from $1,269 million for the comparable quarter a year ago. EBITDA As Defined for the quarter increased 20% to $1,583 million compared with $1,320 million in the comparable quarter a year ago. EBITDA As Defined as a percentage of net sales for the quarter was 53.0%, which included approximately two percentage points of dilution from recent acquisitions, compared with 54.2% in the comparable quarter a year ago.

As previously announced on September 28, 2026, TransDigm completed the acquisition of Prince & Izant ("P&I") for approximately $1.07 billion in cash, including certain tax benefits. P&I is a global designer and manufacturer of highly engineered brazing alloys and specialty metal components used across a range of advanced performance and high cost-of-failure applications. P&I primarily supports the aerospace and defense, aeroderivative turbine, and transportation end markets. Additionally, but to a lesser degree, P&I serves the medical and general industrial end markets. 1

During the quarter, on September 28, 2026, TransDigm successfully completed a private offering of $3.0 billion of new 6.75% Senior Secured Notes maturing January 2035. TransDigm used the net proceeds of the offering of the 2035 Senior Secured Notes to repurchase approximately $1.8 billion of its $2.1 billion outstanding 6.75% Senior Secured Notes due 2028 pursuant to a concurrent tender offer, and for general corporate purposes.

During the fourth quarter of fiscal 2026, TransDigm returned $943 million to shareholders through share repurchases totaling 820 thousand shares of its common stock at an average price per share of $1,150. For the full 2026 fiscal year, TransDigm returned $2.8 billion to shareholders through share repurchases totaling 2.3 million shares of its common stock at an average price per share of $1,187.

Fiscal 2026 net sales increased 20%, or $1,726 million, to $10,557 million from $8,831 million in the comparable period a year ago. Organic sales growth as a percentage of net sales for fiscal 2026 was 11%, and 13% excluding non-aerospace sales.

Fiscal 2026 net income increased $34 million, or 2%, to $2,108 million from $2,074 million in the comparable period a year ago. The increase in net income primarily reflects the increase in net sales described above and the application of our value-driven operating strategy. The increase was offset by higher selling and administrative expenses and higher interest expense.

GAAP earnings per share were reduced in fiscal 2026 and 2025 by $1.03 per share and $3.58 per share, respectively, as a result of dividend equivalent payments made during each year. As a reminder, GAAP earnings per share are reduced when TransDigm makes dividend equivalent payments pursuant to its stock option plans. These dividend equivalent payments are made during TransDigm's first fiscal quarter each year and also upon payment of any special dividends.

Fiscal 2026 adjusted net income increased 10% to $2,383 million, or $41.35 per share, from $2,171 million, or $37.33 per share, in fiscal 2025.

Fiscal 2026 EBITDA increased 14% to $5,217 million from $4,568 million in fiscal 2025. EBITDA As Defined for fiscal 2026 increased 17% to $5,563 million compared with $4,760 million in fiscal 2025. EBITDA As Defined as a percentage of net sales for fiscal 2026 was 52.7% compared with 53.9% in fiscal 2025.

"We are pleased with our team's performance and the overall operating results for both the fourth quarter and the full fiscal year," stated Mike Lisman, TransDigm Group's Chief Executive Officer. "Our fourth quarter results exceeded the high end of our most recent guidance for both revenue and EBITDA As Defined. Our EBITDA As Defined margin for the year ended at 52.7% which includes approximately two percentage points of dilution related to recent acquisitions.

Fiscal 2026 was a very successful year for TransDigm with over $7 billion in capital deployed through a combination of M&A and share repurchases. We invested approximately $4.4 billion in acquisitions including Simmonds Precision Products, Jet Parts Engineering, Victor Sierra Aviation, Prince & Izant, and twelve bolt-on acquisitions at the Operating Unit level. Fiscal 2026 was also a record year for share repurchases totaling approximately $2.8 billion. 2 We enter fiscal 2027 with significant liquidity and the financial flexibility to pursue additional M&A and other capital deployment opportunities."

Please see the attached tables for a reconciliation of net income to EBITDA, EBITDA As Defined, and adjusted net income; a reconciliation of net cash provided by operating activities to EBITDA and EBITDA As Defined; and a reconciliation of earnings per share to adjusted earnings per share for the periods discussed in this press release.

Mr. Lisman stated, "We are issuing full year fiscal 2027 guidance today, which reflects our current expectations for the year. We are well-positioned for continued growth as we head into our fiscal 2027 across all three of our primary end markets."

Net sales are anticipated to be in the range of $11,950 million to $12,150 million compared with $10,557 million in fiscal 2026, an increase of 14% at the midpoint;

Net income is anticipated to be in the range of $2,442 million to $2,490 million compared with $2,108 million in fiscal 2026, an increase of 17% at the midpoint;

Earnings per share is expected to be in the range of $42.06 to $42.91 per share based upon weighted average shares outstanding of 56.7 million shares, compared with $35.51 per share in fiscal 2026, which is an increase of 20% at the midpoint;

EBITDA As Defined is anticipated to be in the range of $6,195 million to $6,345 million compared with $5,563 million in fiscal 2026, an increase of 13% at the midpoint (corresponding to an EBITDA As Defined margin guide of approximately 52.0% for fiscal 2027);

Adjusted earnings per share is expected to be in the range of $47.09 to $47.94 per share compared with $41.35 per share in fiscal 2026, an increase of 15% at the midpoint compared to prior year; and

◦ Commercial OEM revenue growth in the high single-digit to low double-digit percentage range;

◦ Commercial aftermarket revenue growth in the high single-digit percentage range; and

Please see the attached Table 6 for a reconciliation of EBITDA, EBITDA As Defined to net income and reported earnings per share to adjusted earnings per share guidance midpoint estimated for the fiscal year ending September 30, 2027. 3

EBITDA, EBITDA As Defined, EBITDA As Defined margin, adjusted net income and adjusted earnings per share are non-GAAP financial measures presented in this press release as supplemental disclosures to net income and reported results. TransDigm Group defines EBITDA as earnings before interest, taxes, depreciation and amortization and defines EBITDA As Defined as EBITDA plus certain non- operating items recorded as corporate expenses, including non-cash compensation charges incurred in connection with TransDigm Group's stock option or deferred compensation plans, foreign currency gains and losses, acquisition-integration costs, acquisition transaction-related expenses, and refinancing costs. Acquisition transaction and integration-related expenses represent costs incurred to integrate acquired businesses into our operations; facility relocation costs and other acquisition-related costs; transaction and valuation- related costs for acquisitions comprising deal fees, legal, financial and tax due diligence expenses; and amortization expense of inventory step-up recorded in connection with the purchase accounting of acquired businesses. TransDigm Group defines adjusted net income as net income plus purchase accounting backlog amortization expense, effects from the sale of businesses, non-cash compensation charges incurred in connection with TransDigm Group's stock option or deferred compensation plans, foreign currency gains and losses, acquisition-integration costs, acquisition transaction-related expenses, and refinancing costs. EBITDA As Defined margin represents EBITDA As Defined as a percentage of net sales. TransDigm Group defines adjusted diluted earnings per share as adjusted net income divided by the total outstanding shares for basic and diluted earnings per share. For more information regarding the computation of EBITDA, EBITDA As Defined, adjusted net income and adjusted earnings per share, please see the attached financial tables. 5 TransDigm Group presents these non-GAAP financial measures because it believes that they are useful indicators of its operating performance. TransDigm Group believes that EBITDA is useful to investors because it is frequently used by securities analysts, investors and other interested parties to measure operating performance among companies with different capital structures, effective tax rates and tax attributes, capitalized asset values and employee compensation structures, all of which can vary substantially from company to company. In addition, analysts, rating agencies and others use EBITDA to evaluate a company’s ability to incur and service debt. EBITDA As Defined is used to measure TransDigm Inc.’s compliance with the financial covenant contained in its credit facility. TransDigm Group’s management also uses EBITDA As Defined to review and assess its operating performance, to prepare its annual budget and financial projections and to review and evaluate its management team in connection with employee incentive programs. Moreover, TransDigm Group’s management uses EBITDA As Defined to evaluate acquisitions and as a liquidity measure. In addition, TransDigm Group’s management uses adjusted net income as a measure of comparable operating performance between time periods and among companies as it is reflective of changes in pricing decisions, cost controls and other factors that affect operating performance.

None of EBITDA, EBITDA As Defined, EBITDA As Defined margin, adjusted net income or adjusted earnings per share is a measurement of financial performance under U.S. GAAP and such financial measures should not be considered as an alternative to net income, operating income, earnings per share, cash flows from operating activities or other measures of performance determined in accordance with U.S. GAAP. In addition, TransDigm Group’s calculation of these non-GAAP financial measures may not be comparable to the calculation of similarly titled measures reported by other companies.

Although we use EBITDA and EBITDA As Defined as measures to assess the performance of our business and for the other purposes set forth above, the use of these non-GAAP financial measures as analytical tools has limitations, and you should not consider any of them in isolation, or as a substitute for analysis of our results of operations as reported in accordance with U.S. GAAP. Some of these limitations are:

neither EBITDA nor EBITDA As Defined reflects the significant interest • expense, or the cash requirements, necessary to service interest payments on our indebtedness;

although depreciation and amortization are non-cash charges, the assets • being depreciated and amortized will often have to be replaced in the future, and neither EBITDA nor EBITDA As Defined reflects any cash requirements for such replacements;

the omission of the substantial amortization expense associated with • our intangible assets further limits the usefulness of EBITDA and EBITDA As Defined;

• neither EBITDA nor EBITDA As Defined includes the payment of taxes, which is a necessary element of our operations; and

EBITDA As Defined excludes the cash expense we have incurred to • integrate acquired businesses into our operations, which is a necessary element of certain of our acquisitions.

(5) The EBITDA As Defined Margin represents the amount of EBITDA As Defined as a percentage of net sales.

For the thirteen week periods and fiscal years ended September 30, 2026 and September 30, 2025, the Tax adjustment represents the tax effect of the adjustments at the applicable effective tax rate, as well as the impact on the effective tax rate when excluding the (1) excess tax benefits on stock option exercises. Stock compensation expense is excluded from adjusted net income and therefore we have excluded the impact that the excess tax benefits on stock option exercises have on the effective tax rate for determining adjusted net income.

    TransDigm Group Reports Fiscal 2026 Fourth Quarter and Year-End Results     
Cleveland, Ohio, November 10, 2026/PRNewswire/ -- TransDigm Group Incorporated
(NYSE: TDG), a leading global designer, producer and supplier of highly
engineered aircraft components, today reported results for the fourth quarter
ended September 30, 2026.

Fourth quarter highlights include:

Net sales of $2,988 million, up 23% from $2,437 million in the prior year's
quarter;

• Earnings per share of $10.33, up 33% from $7.75 in the prior year's quarter;

• EBITDA As Defined of $1,583 million, up 20% from $1,320 million in the prior
year's quarter; and

• Adjusted earnings per share of $12.44, up 15% from $10.82 in the prior year's
quarter.

percentage of net sales was 14%.

Net income for the quarter was $586 million, a decrease of $23 million, or 4%,
compared to $609 million in the comparable quarter a year ago. The decrease in
net income primarily reflects higher interest expense as a result of the
increase in TransDigm's year-over-year gross debt balance and higher tax
expense. The decrease was offset by the increase in net sales as described above
and the application of our operating strategy.

Adjusted net income for the quarter increased 12% to $706 million, or $12.44 per
share, from $629 million, or $10.82 per share, in the comparable quarter a year
ago.

EBITDA for the quarter increased 13% to $1,436 million from $1,269 million for

recent acquisitions, compared with 54.2% in the comparable quarter a year ago.

During the fourth quarter of fiscal 2026, TransDigm returned $943 million to
shareholders through share repurchases totaling 820 thousand shares of its
common stock at an average price per share of $1,150. For the full 2026 fiscal
year, TransDigm returned $2.8 billion to shareholders through share repurchases
totaling 2.3 million shares of its common stock at an average price per share of
$1,187.
                                                                                
   Year-to-Date Results                                                         
                                                                                
Fiscal 2026 net sales increased 20%, or $1,726 million, to $10,557 million from
$8,831 million in the comparable period a year ago. Organic sales growth as a
percentage of net sales for fiscal 2026 was 11%, and 13% excluding non-aerospace
sales.

Fiscal 2026 net income increased $34 million, or 2%, to $2,108 million from
$2,074 million in the comparable period a year ago. The increase in net income
primarily reflects the increase in net sales described above and the application
of our value-driven operating strategy. The increase was offset by higher
selling and administrative expenses and higher interest expense.

GAAP earnings per share were reduced in fiscal 2026 and 2025 by $1.03 per share
and $3.58 per share, respectively, as a result of dividend equivalent payments
made during each year. As a reminder, GAAP earnings per share are reduced when
TransDigm makes dividend equivalent payments pursuant to its stock option plans.
These dividend equivalent payments are made during TransDigm's first fiscal
quarter each year and also upon payment of any special dividends.

Fiscal 2026 adjusted net income increased 10% to $2,383 million, or $41.35 per
share, from $2,171 million, or $37.33 per share, in fiscal 2025.

Fiscal 2026 EBITDA increased 14% to $5,217 million from $4,568 million in fiscal
2025. EBITDA As Defined for fiscal 2026 increased 17% to $5,563 million compared
with $4,760 million in fiscal 2025. EBITDA As Defined as a percentage of net
sales for fiscal 2026 was 52.7% compared with 53.9% in fiscal 2025.

"We are pleased with our team's performance and the overall operating results
for both the fourth quarter and the full fiscal year," stated Mike Lisman,
TransDigm Group's Chief Executive Officer. "Our fourth quarter results exceeded
the high end of our most recent guidance for both revenue and EBITDA As Defined.
Our EBITDA As Defined margin for the year ended at 52.7% which includes
approximately two percentage points of dilution related to recent acquisitions.

Fiscal 2026 was a very successful year for TransDigm with over $7 billion in
capital deployed through a combination of M&A and share repurchases. We invested
approximately $4.4 billion in acquisitions including Simmonds Precision
Products, Jet Parts Engineering, Victor Sierra Aviation, Prince & Izant, and
twelve bolt-on acquisitions at the Operating Unit level. Fiscal 2026 was also a
record year for share repurchases totaling approximately $2.8 billion.
                                       2                                        
We enter fiscal 2027 with significant liquidity and the financial flexibility to
pursue additional M&A and other capital deployment opportunities."

Mr. Lisman stated, "We are issuing full year fiscal 2027 guidance today, which

continued growth as we head into our fiscal 2027 across all three of our primary
end markets."

Earnings per share is expected to be in the range of $42.06 to $42.91 per share
based upon weighted average shares outstanding of 56.7 million shares, compared

  Non-GAAP Supplemental Information                                             
                                                                                
EBITDA, EBITDA As Defined, EBITDA As Defined margin, adjusted net income and
adjusted earnings per share are non-GAAP financial measures presented in this
press release as supplemental disclosures to net income and reported results.
TransDigm Group defines EBITDA as earnings before interest, taxes, depreciation
and amortization and defines EBITDA As Defined as EBITDA plus certain non-
operating items recorded as corporate expenses, including non-cash compensation
charges incurred in connection with TransDigm Group's stock option or deferred
compensation plans, foreign currency gains and losses, acquisition-integration
costs, acquisition transaction-related expenses, and refinancing costs.
Acquisition transaction and integration-related expenses represent costs
incurred to integrate acquired businesses into our operations; facility
relocation costs and other acquisition-related costs; transaction and valuation-
related costs for acquisitions comprising deal fees, legal, financial and tax
due diligence expenses; and amortization expense of inventory step-up recorded
in connection with the purchase accounting of acquired businesses. TransDigm
Group defines adjusted net income as net income plus purchase accounting backlog
amortization expense, effects from the sale of businesses, non-cash compensation
charges incurred in connection with TransDigm Group's stock option or deferred
compensation plans, foreign currency gains and losses, acquisition-integration
costs, acquisition transaction-related expenses, and refinancing costs. EBITDA
As Defined margin represents EBITDA As Defined as a percentage of net sales.
TransDigm Group defines adjusted diluted earnings per share as adjusted net
income divided by the total outstanding shares for basic and diluted earnings
per share. For more information regarding the computation of EBITDA, EBITDA As
Defined, adjusted net income and adjusted earnings per share, please see the
attached financial tables.
                                       5                                        
TransDigm Group presents these non-GAAP financial measures because it believes
that they are useful indicators of its operating performance. TransDigm Group
believes that EBITDA is useful to investors because it is frequently used by
securities analysts, investors and other interested parties to measure operating
performance among companies with different capital structures, effective tax
rates and tax attributes, capitalized asset values and employee compensation
structures, all of which can vary substantially from company to company. In
addition, analysts, rating agencies and others use EBITDA to evaluate a
company’s ability to incur and service debt. EBITDA As Defined is used to
measure TransDigm Inc.’s compliance with the financial covenant contained in its
credit facility. TransDigm Group’s management also uses EBITDA As Defined to
review and assess its operating performance, to prepare its annual budget and
financial projections and to review and evaluate its management team in
connection with employee incentive programs. Moreover, TransDigm Group’s
management uses EBITDA As Defined to evaluate acquisitions and as a liquidity
measure. In addition, TransDigm Group’s management uses adjusted net income as a
measure of comparable operating performance between time periods and among
companies as it is reflective of changes in pricing decisions, cost controls and
other factors that affect operating performance.

None of EBITDA, EBITDA As Defined, EBITDA As Defined margin, adjusted net income
or adjusted earnings per share is a measurement of financial performance under
U.S. GAAP and such financial measures should not be considered as an alternative
to net income, operating income, earnings per share, cash flows from operating
activities or other measures of performance determined in accordance with U.S.
GAAP. In addition, TransDigm Group’s calculation of these non-GAAP financial
measures may not be comparable to the calculation of similarly titled measures
reported by other companies.

Although we use EBITDA and EBITDA As Defined as measures to assess the
performance of our business and for the other purposes set forth above, the use
of these non-GAAP financial measures as analytical tools has limitations, and
you should not consider any of them in isolation, or as a substitute for
analysis of our results of operations as reported in accordance with U.S. GAAP.
Some of these limitations are:
                                                                                
       neither EBITDA nor EBITDA As Defined reflects the significant interest   
  •    expense, or the cash requirements, necessary to service interest         
       payments on our indebtedness;                                            
                                                                                
                                                                                
       although depreciation and amortization are non-cash charges, the assets  
  •    being depreciated and amortized will often have to be replaced in the    
       future, and neither EBITDA nor EBITDA As Defined reflects any cash       
       requirements for such replacements;                                      
                                                                                
                                                                                
       the omission of the substantial amortization expense associated with     
  •    our intangible assets further limits the usefulness of EBITDA and        
       EBITDA As Defined;                                                       
                                                                                
                                                                                
  •    neither EBITDA nor EBITDA As Defined includes the payment of taxes,      
       which is a necessary element of our operations; and                      
                                                                                
                                                                                
       EBITDA As Defined excludes the cash expense we have incurred to          
  •    integrate acquired businesses into our operations, which is a necessary  
       element of certain of our acquisitions.

         For the thirteen week periods and fiscal years ended September 30,     
         2026 and September 30, 2025, the Tax adjustment represents the tax     
         effect of the adjustments at the applicable effective tax rate, as     
         well as the impact on the effective tax rate when excluding the        
  (1)    excess tax benefits on stock option exercises. Stock compensation      
         expense is excluded from adjusted net income and therefore we have     
         excluded the impact that the excess tax benefits on stock option       
         exercises have on the effective tax rate for determining adjusted net  
         income.
