Greetings, and welcome to Innovative Solutions & Support, Inc. First Quarter 2023 Earnings Conference Call. At this time, all participants are in a listen-only mode. A brief question and answer session will follow the formal presentation. If anyone should require operator assistance during the conference, please press star zero on your telephone keypad. As a reminder, this conference is being recorded. It is now my pleasure to introduce your host, Michael Linacre. Thank you. Mr. Linacre, you may begin.
Thank you, operator, and good afternoon, everyone. I would remind our listeners that certain matters discussed in the conference call today, including information about new products and operational and financial results for future periods, are forward-looking statements that are subject to risks and uncertainties that could cause actual results to differ materially, either better or worse, from those discussed, including other risks and uncertainties reflected in our company's 10-K, which is on file with the SEC and other public filings. Now, I'll turn it over to our CEO, Shahram Askarpour.
Thank you, Mike, good afternoon, everyone. I will begin today with remarks on our performance in the fiscal first quarter of 2023, followed by comments on the upcoming year and our long-term growth strategy. I will turn the call over to Mike, who will take us through the details of the financials. We began the year on solid footing with revenues of $6.5 million, driven by stronger OEM volume and engineering development contracts. Underlying end markets remain strong, particularly with OEM customers. I'm pleased to announce that during the Q1 2023 period, we received our FAA Supplemental Type Certificate, or STC, for the King Air with the G1000 and NXi flight decks, and delivered our first aircraft. This STC opens an additional 700 potential aircraft for our King Air autothrottle, which builds on the existing growing aftermarket King Air platforms.
As we have stated in the past quarters, our winning formula starts with excellent products in attractive growing markets. This effort is supported by more than 500 cockpit upgrades in 757, 767, and 737 platforms, combined with a rapidly growing presence in general aviation. Gross profit in the first quarter was $3.7 million, compared to $4 million in the prior year, mainly due to product mix. As a percentage of sales, gross margin was 57.1% compared to 59.3% in the prior year. We believe these results reflect the success of our innovative products in the market and our dedication to excellence in delivering for our customers.
Turning to product development and beginning with autothrottle, we continue to invest in additional platforms that benefit from our ThrustSense products, as well as increased functionality that help generate additional revenue. Our B 757/767 Engine Indicating and Crew Alerting System upgrade development program is progressing well. We expect this additional offering on our successful 757/767 platforms to generate solid revenue for years to come. We also remain laser-focused on the short-term opportunity to meaningfully expand margins through better facility utilization and intend to accomplish this goal through a mix of organic growth and strategic bolt-on M&A. On the organic side, we continue to expect an expansion of our R&D program in fiscal 2023 to around 13% of sales from 10% in fiscal 2022.
The first quarter, our R&D ran below this level as we are in the process of ramping up our engineering resources. Cockpit automation remains a focus area for us, as demonstrated with the development of the autothrottle for King Air, PC-12 and Eclipse. Beyond autothrottle, on attractive product line type acquisitions that complement our existing portfolio. We expect to be able to fund bolt-on acquisitions through cash on the balance sheet and free cash flows from operations, which exceeded $6 million in fiscal 2022. Taken together, we believe we can grow our sales, increase our asset utilization, and drive incremental margin to overall business.
At full capacity, we believe our infrastructure can support a meaningful increase to our operating results and total free cash flow. To conclude, we're off to a good start for the year with a strong outlook as we deliver on our legacy products and new offerings. Thank you for your time and interest, and we look forward to updating you with further details in the upcoming quarters. Now I will turn the call over to Mike for a closer look at the numbers.
Thank you, Shahram, and thank you all for joining us today. I will review our financial results for the first quarter of fiscal 2023. Revenues declined slightly by 2.7% to $6.5 million in the first quarter versus $6.7 million in the first quarter of fiscal 2022. Decrease was largely due to lower commercial aftermarket revenue, which is partially offset by growth in our general aviation OEM business. The decrease in commercial sales was primarily a function of when the sales orders were received for our aftermarket retrofit business from commercial air transport customers. These orders may fluctuate from quarter to quarter, but we continue to anticipate that sales will support the short-term organic growth trajectories. Demand from our OEM business remained strong during the quarter.
Sales from engineering development contracts, or EDC, improved as a result of two research and development projects. Customer service revenue was consistent with prior year. New orders in the first quarter were approximately $3.3 million, and backlog was $8.5 million as of December 31st, 2022. Backlog is up from $6.2 million as of December 31st, 2021. We include only purchase orders in-hand from the Pilatus PC-24, Textron King Air, and the KC-46A long-term program in our total backlog. The current backlog includes a large contract with one of our general aviation OEMs that is locking in their supply chain beyond their normal advanced order. Given this increase, total backlog levels do not necessarily translate to increased future sales.
We anticipate that these programs will remain in production for about a decade and should continue to add to production sales already included in the backlog. First quarter gross margin was 57.1% versus 59.3% in the first quarter period from a year ago. Cost of sales increased due to the combination of higher, less profitable OEM business, lower product sales, and slightly higher direct material costs, which adversely impacted our operating leverage. Note that all our long-term OEM production contracts include escalation clauses that provide for the passing along of a portion of cost increases incurred as a result of inflationary pressures. As we've mentioned on previous calls, our optimized operating model is based on a fixed cost platform with relatively lower employee headcount. We expect our operating leverage and margin profile to improve as sales growth returns over the remainder of the year.
Total operating expenses were $2.9 million in the first quarter, compared to $2.5 million in the prior year first quarter. The uptick in general administrative expenses in the quarter was mainly on account of non-cash, long-term employee stock compensation and professional and legal fees. Higher G&A costs are expected to continue into the second quarter and moderate into the second half of the year. The growth in operating expenses was offset in part by higher interest income generated from the combination of a larger amount of balance sheet cash, higher interest rates, and the reallocation of funds into higher interest yielding investments compared to the same period in the prior year. R&D expenses were approximately 11% of revenue and in line with a year ago first quarter levels.
Our expectation of targeting 13% of revenue for R&D in 2023 is unchanged. We therefore expect R&D expenses to gradually rise over the coming quarters. Tax expense in the first quarter was $0.2 million, compared to $0.3 million in the prior year quarter. First quarter net income was $0.7 million or $0.04 per share, versus $1.1 million or $0.07 per share in the first quarter of fiscal 2022. IS&S maintains ample flexibility driven by a significant liquidity and a debt-free balance sheet, which enables us to be very well positioned to capitalize on organic and inorganic opportunities. We had $19.4 million of cash on hand as of December 31st, 2022, up from $17.3 million at the end of fiscal 2022.
The company generated cash flows of $1.8 million from operations and received net cash of $0.4 million from financing activities from the exercise of stock options during the quarter. Looking at the remainder of fiscal 2023, we expect to continue to generate strong cash flows with the maintenance of current gross margin levels and cost control. We anticipate increasing our capacity utilization and expanding operating leverage as we drive revenue growth by capitalizing on organic and inorganic opportunities through the remainder of the year. With that, operator, we are ready for any questions.

Our first question comes from David Campbell with Thompson Davis. Please go ahead.
Thank you for taking my question and congratulations on a solid quarter. I'm surprised the general administration expense $2.1 million, I believe it was, in the quarter. Does that reflect the creation of your team to look for additional opportunities or different products that you may acquire in this so, will you continue to generate that $2.1 million every quarter?
The actual operating expenses were $2.9 versus $2.5 last year. That's part of the increase is what, is what you mentioned, really a lot of this came up with that as a direct result of the passing of our founder. You know, going forward, we have a long-term compensation and a bonus plan in place that we have not had before that will put us more in line with our peers in the industry. A lot of this, you know, having said that, a lot of these expenses are in stock. There's not a cash impact. You can see that we generated $1.8 million in the quarter of free cash flows. Not affecting the company's ability to generate cash. You know, also some one-time legal fees in there, bringing the company in line with peers as far as corporate governance, and other, temporary, more costs are temporary in nature.
Well, it sounds like some of this was a temporary cost, related to the stock options and other expenses that you may not have in the rest of the year. Should we anticipate that trucking general and administrative expenses should go down from where they were in the first quarter?
I would say the run rate will be. There are some temporary costs in there, some one-time costs. They will be lower than we ran in the first quarter. I think generally, they will be up from historic run rates, just based on our new long-term compensation incentive as well as bonuses, as well as investing into the team, for future growth.
Yeah. You mentioned an impact from the founders dying a year ago. How was that an impact?
Well, our former founder did own 20% of our shares. You know, and we did from time to time issue special dividends that was effectively his long-term compensation plan. You know, to kind of replace that and offer our current executives and management team a long-term incentive plan, who don't own that percentage of shares, we needed to, you know, increase that G&A item.
Your interest income was a substantial amount. Is anything non-recurring about that? You know, I realize interest rates are higher, and that's why that happened, at least some of it. But, I'm surprised that it was this much up this much all of a sudden.
If you look at our cash, you know, from year- to- year, our cash more than doubled last year. We ended the year at over $17 million. We have over $19 million in the first quarter. We only had, you know, $9 million at the end of last fiscal 2021 year end. It's a combination of having more cash. Interest rates are also a lot higher now than they were a year ago. We also did reallocate some of the funds to higher yielding interest accounts as well.
Right. Have you had any impact from Airbus converting their cargo? More of their equipment is being converted from passenger to cargo use, which has benefited your company's Boeing contracts. Do you see any plan in Airbus developing the same relationship?
We currently don't have a cockpit upgrade system for the Airbus fleet being converted to cargo. We continue delivering on our 737, 757, 767 cockpits for cargo conversion, as well as other airline operators as they looking to upgrade their cockpits. We see that kind of a steady demand that we've had now continue in general. We've also putting together a replacement for the EICAS system in there, which is the Engine Indication and Crew Alerting. We should augment those cockpits as well as opportunity to go to a big chunk of those 500 airplanes that are out there and offer them, you know, an additional upgrade.
I've seen where UPS and FedEx are grounding, several of their aircraft, their older aircraft, which tells me that their demand for capacity is down. Have you seen any impact on your customers from that trend?
Not significantly. I mean, this has always been the aftermarket on the 757/ 767 has always been for us kind of cyclic. You know, we get a few years off and then it kind of goes down, and it varies between, I guess, $5 million-$7 million a year. I don't see it getting out of that range anytime soon. You know, it's gonna have some years, gonna be more, some years are gonna be less.
Right. Well, air freight rates jumped, you know, two years ago, but they're now down to normal levels. The airlines aren't experiencing the same demand factors as they had, but, I think.
The passengers are off significantly.
Yeah.
Again, our cockpit is not necessarily tied into cargo operations. It's applicable. I mean, Icelandair is one of our customers and, you know, we provide a cockpit for 757, 767, on their passenger airlines.
All right. Well, thank you very much. I appreciate your hard work. Keep up the good work.
Thank you, David.
Thank you, David.
Thank you.
